Description

Technical Field

[0001] The present application relates to the field of vehicles, and more particularly, to a vehicle starting method, a vehicle starting device, and a vehicle in the field of vehicles. Background Art

[0002] Nowadays, with the popularity of motor vehicles, more and more people choose to drive motor vehicles for travel. When starting a motor vehicle, in order to facilitate the vehicle starting process, the motor vehicle is equipped with a one-button start function, which triggers the start button to find a legal key to start the motor vehicle.

[0003] In related technologies, when a motor vehicle is started through the one-button start function, the motor vehicle sends a low-frequency signal to search for a legitimate key, and completes the start-up based on the signal sent by the legitimate key in response to the low-frequency signal. If there is an interference signal around the motor vehicle, the motor vehicle may not be able to receive the signal returned by the legitimate key, resulting in a failure to start the motor vehicle and affecting the starting function of the motor vehicle. Summary of the Invention

[0004] The present application provides a vehicle starting method, device and vehicle. The method can prevent the battery from over-powering and causing unnecessary damage to the battery by limiting the power of the target motor, while avoiding affecting the operation of the remaining motors and affecting the user's driving experience, thereby improving the user's driving experience and the safety and stability of the vehicle.

[0005] In a first aspect, a vehicle starting method is provided, which is applied to a vehicle and includes:

[0006] In response to a start-up command for the vehicle, if the first radio frequency transceiver component of the vehicle does not receive a first feedback signal from a vehicle key within a first time period, controlling the second radio frequency transceiver component of the vehicle to output a second key request signal;

[0007] If the second RF transceiver component receives a second feedback signal from the vehicle key within a second time period, verifying the key information in the second feedback signal and controlling the vehicle to start after the verification passes;

[0008] The first feedback signal is a signal generated by the vehicle key in response to the first key request signal output by the first radio frequency transceiver component, and the second feedback signal is a signal generated by the vehicle key in response to the second key request signal. The first transmission frequency set used by the first feedback signal is different from the second transmission frequency set used by the second feedback signal.

[0009] Through the above technical solution, it is possible to receive feedback signals output by the vehicle key using different transmission frequency sets, determine that the vehicle key is near the vehicle based on the feedback signal, and control the vehicle start-up, thereby avoiding interference signals around the vehicle through different transmission frequency sets, thereby improving the reliability and stability of vehicle start-up.

[0010] In conjunction with the first aspect, in some possible implementations, controlling the second radio frequency transceiver component of the vehicle to output the second key request signal includes:

[0011] controlling a second radio frequency transceiver component of the vehicle to generate a second key request signal based on a second component identifier of the second radio frequency transceiver component, wherein the second key request signal includes a second frequency indication identifier and a second request identifier of the second key request signal;

[0012] Control the second radio frequency transceiver component to output the second key request signal.

[0013] Through the above technical solution, the second frequency indication identifier can be used to indicate the second sending frequency set used by the vehicle key to output the second feedback signal, thereby increasing the possibility of the second feedback signal avoiding interference and further improving the reliability of vehicle starting.

[0014] In combination with the first aspect and the above implementation manner, in some possible implementation manners, verifying the key information in the second feedback signal and controlling the vehicle to start after the verification passes includes:

[0015] controlling the second radio frequency transceiver component to parse the second feedback signal to obtain a second signal identifier;

[0016] If the second signal identifier matches the second request identifier, determining that the second feedback signal passes verification and controlling the vehicle to start;

[0017] If the second signal identifier does not match the second request identifier, it is determined that the second feedback signal fails the verification.

[0018] In combination with the first aspect and the above implementations, in some possible implementations, before controlling the second radio frequency transceiver component of the vehicle to output the second key request signal, the method further includes:

[0019] controlling the first radio frequency transceiver component to output a trigger signal to the second radio frequency transceiver component;

[0020] The second radio frequency transceiver component is controlled to output a second key request signal in response to the trigger signal.

[0021] Through the above technical solution, according to the different conditions of the first RF transceiver component and the second RF transceiver component, corresponding methods can be used to output the key request signal and receive and verify the feedback signal, thereby improving the versatility of vehicle starting when the RF components adopt different design methods.

[0022] In combination with the first aspect and the above implementations, in some possible implementations, controlling the vehicle to start after the verification is passed includes:

[0023] After the verification is passed, controlling the second radio frequency transceiver component to output a start signal to the first radio frequency transceiver component;

[0024] The first radio frequency transceiver component is controlled to start the vehicle in response to the start signal.

[0025] In combination with the first aspect and the above implementations, in certain possible implementations, if a first RF transceiver component of the vehicle receives a first feedback signal from the vehicle key within a first duration, the first RF transceiver component is controlled to parse the first feedback signal to obtain a first signal identifier, where a first transmission frequency set used by the first feedback signal is determined by the vehicle key based on a first frequency indication identifier in a first key request signal;

[0026] If the first signal identifier matches the first request identifier of the first key request signal, it is determined that the first feedback signal passes verification, and the vehicle is controlled to start. The first request identifier is generated by the first RF transceiver component based on the first component identifier of the first RF transceiver component.

[0027] In a second aspect, a vehicle starting method is provided, which is applied to a vehicle key, and the method includes:

[0028] In response to a first key request signal output by a first radio frequency transceiver component of the vehicle, outputting a first feedback signal using a first set of transmission frequencies;

[0030] outputting the second feedback signal using the second set of transmission frequencies, so that the vehicle verifies the second feedback signal, and controlling the vehicle to start after passing the verification;

[0031] The first transmission frequency set is different from the second transmission frequency set. The first key request signal is output by the first radio frequency transceiver component, and the second key request signal is output by the second radio frequency transceiver component of the vehicle.

[0032] Through the above technical solution, the vehicle key can output feedback signals multiple times using different transmission frequency sets, so that the vehicle can determine that the vehicle key is near the vehicle based on the feedback signal output by the received vehicle key, and control the vehicle start-up, thereby avoiding the interference signals around the vehicle through different transmission frequency sets, thereby improving the reliability and stability of vehicle start-up.

[0033] In conjunction with the second aspect, in some possible implementations, generating a second feedback signal in response to a second key request signal, and determining a second transmission frequency set based on the second key request signal, includes:

[0035] A second feedback signal is generated based on the second signal identifier, and a second transmission frequency set is determined based on the second frequency indication identifier. The second feedback signal includes multiple second feedback data packets, and the second feedback data packets include the second signal identifier corresponding to the second request identifier.

[0036] Through the above technical solution, a feedback signal can be generated according to the identifier in the key request signal, and the adopted transmission frequency set can be determined, thereby improving the accuracy and reliability of the feedback signal output by the vehicle key.

[0037] In combination with the second aspect and the foregoing implementation, in some possible implementations, determining the second transmission frequency set based on the second frequency indication identifier includes:

[0038] If the second frequency indication identifier is a micro-frequency hopping indication identifier, determining that the second sending frequency set includes a second center frequency and a second micro-hopping frequency, and the second center frequency and the second micro-hopping frequency are different frequencies in the same frequency band;

[0041] Using the second center frequency and the second microhop frequency, polling and outputting each second feedback data packet based on the first interval duration; or,

[0042] The second center frequency and the first center frequency are used to poll and output each of the second feedback data packets based on a first interval duration.

[0043] Through the above technical solution, the second feedback data packet in the second feedback signal can be outputted by adopting different sending frequencies, thereby avoiding the interference existing in the environment around the vehicle, and by providing different frequency set options, the probability of avoiding interference signals is increased, thereby improving the stability of successful vehicle startup.

[0044] In combination with the second aspect and the above implementations, in some possible implementations, the step of outputting a first feedback signal using a first transmission frequency set in response to a first key request signal output by a first radio frequency transceiver component of the vehicle includes:

[0046] generating a first feedback signal based on the first request identifier, where the first feedback signal includes a plurality of first feedback data packets, each of which includes a first signal identifier corresponding to the first request identifier;

[0077] The following will clearly and thoroughly describe the technical solutions in this application in conjunction with the accompanying drawings. In the description of the embodiments of this application, unless otherwise specified, " / " means or, for example, A / B can mean A or B: "and / or" in the text is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the description of the embodiments of this application, "multiple" means two or more than two.

[0078] In the following, the terms "first" and "second" are used for descriptive purposes only and should not be understood to imply or suggest relative importance or implicitly indicate the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0079] Figure 1 This is a system architecture diagram of a vehicle starting method provided by an embodiment of the present application. Figure 1 As shown, the vehicle starting method provided in the embodiment of the present application can be applied to a vehicle to realize the process of starting the vehicle. The system architecture provided in the embodiment of the present application mainly includes a vehicle 10 and a vehicle key 20. Among them, the vehicle 10 can be a motor vehicle, for example, a fuel vehicle, a hybrid vehicle or an electric vehicle; the vehicle 10 includes a first RF transceiver component 11, a second RF transceiver component 12 and a related controller. The first RF transceiver component 11 and the second RF transceiver component 12 can be components that output RF signals in the vehicle, and the related controller 13 can be a controller that controls various components in the vehicle, for example, an engine controller; the vehicle key 20 can be a key paired with the vehicle 10.

[0080] The first RF transceiver component 11 and the second RF transceiver component 12 can be the same component or different components. When the first RF transceiver component 11 and the second RF transceiver component 12 are different components, the first RF transceiver component 11 and the second RF transceiver component 12 are transmitted through wired communication.

[0081] When a user starts the vehicle 10, the first RF transceiver assembly 11 outputs a key request signal to detect whether the vehicle key 20 is present near the vehicle 10. Upon receiving the key request signal, the vehicle key 20 outputs a feedback signal. After receiving the feedback signal, the vehicle 10 controls various components of the vehicle 10 through the relevant controller 13 to start the vehicle 10. However, if there is signal interference around the vehicle 10, the vehicle 10 may not be able to receive the feedback signal, resulting in a vehicle startup failure.

[0082] However, through the embodiment of the present application, if the first RF transceiver component 12 does not receive the first feedback signal corresponding to the first key request signal output by the vehicle key 20 within the first time period, the second RF transceiver component 12 generates and outputs a second key request signal, and after receiving the second feedback signal generated by the vehicle key 20 in response to the second key request signal within the second time period, the first RF transceiver component 11 is controlled to start the various components of the vehicle 10 through the relevant controller 13 to complete the vehicle startup.

[0083] based on Figure 1 The system architecture shown below will be combined with Figure 2-Figure 8 , the vehicle starting method provided in the embodiment of the present application is introduced in detail.

[0084] See Figure 2 , provides a process sequence diagram of a vehicle starting method according to an embodiment of the present application. Figure 2 As shown, the method of the embodiment of the present application may include the following steps S101 to S106.

[0085] S101, in response to a start command for a vehicle, if a first radio frequency transceiver component of the vehicle does not receive a first feedback signal from a vehicle key within a first time period, controlling a second radio frequency transceiver component of the vehicle to output a second key request signal;

[0086] In one embodiment, the user starts the vehicle, and the vehicle computer generates a start instruction after receiving the start instruction, and transmits the start instruction to the first RF transceiver component of the vehicle. The first RF transceiver component outputs a first key request signal in response to the start instruction.

[0087] The starting operation can be the operation of starting the vehicle in the vehicle. With the development of technology, in order to provide convenience of operation, in addition to starting the vehicle by inserting the key into the keyhole, it also includes pressing the "one-button start" button to start the vehicle.

[0088] The start instruction may be an instruction for starting the vehicle generated after the vehicle receives a start operation.

[0089] The first radio frequency transceiver component may be a component in the vehicle for outputting a radio frequency signal so as to be paired with the vehicle key according to the radio frequency signal.

[0090] The first key request signal may be a signal generated by the first radio frequency transceiver component to match the vehicle key.

[0091] The vehicle key may be a device paired with the vehicle, including signal receiving and signal output functions.

[0092] S102, in response to a first key request signal output by a first radio frequency transceiver component of the vehicle, outputting a first feedback signal using a first transmission frequency set;

[0093] In one embodiment, after receiving a first key request signal output by a first radio frequency transceiver component of the vehicle, the vehicle key generates a first feedback signal in response to the first key request signal and outputs the first feedback signal using a first transmission frequency set.

[0094] The first feedback signal may be a signal generated by the vehicle key in response to the first key request signal output by the first radio frequency transceiver component.

[0095] The first transmission frequency set may be a set including multiple transmission frequencies, specifically including a first center frequency and a first micro-hop frequency, wherein the first center frequency and the first micro-hop frequency may be different frequencies in the same frequency band.

[0096] S103, if the first radio frequency transceiver component of the vehicle does not receive the first feedback signal from the vehicle key within the first time period, controlling the second radio frequency transceiver component of the vehicle to output a second key request signal;

[0097] In one embodiment, if the first RF transceiver assembly does not receive the first feedback signal from the vehicle key within the first time period, a second key request signal is generated, and the second RF transceiver assembly of the vehicle is controlled to output the second key request signal.

[0098] It is understandable that if the first feedback signal is not received within the first time period, in order to improve the efficiency of vehicle startup, a second key request signal is generated and output to perform a second key request to realize vehicle startup.

[0099] The first time length can be a time length pre-set by the vehicle for waiting to receive the first feedback signal. It is understandable that by setting the first time length to limit the waiting time for the first feedback signal, unnecessary signal waiting is avoided, thereby improving the efficiency of vehicle startup.

[0100] The second RF transceiver component may be a component in the vehicle for outputting a RF signal to pair with the vehicle key according to the RF signal. The first RF transceiver component and the second RF transceiver component may be the same component or different components.

[0101] The second key request signal may be a signal generated by the second radio frequency transceiver component to match the vehicle key.

[0102] S104 , if a second key request signal is received, generating a second feedback signal in response to the second key request signal, and determining a second transmission frequency set based on the second key request signal;

[0103] In one embodiment, if a second key request signal is received after the first feedback signal is output, it is considered that the first feedback signal is not received by the first RF transceiver component of the vehicle, so a second feedback signal is generated in response to the second key request signal, and a second transmission frequency set is determined based on the second key request signal.

[0104] The second feedback signal may be a signal generated by the vehicle key in response to the second key request signal. The second feedback signal includes a second signal identifier, so that the second RF transceiver component of the vehicle can verify the second feedback signal according to the second signal identifier.

[0105] The second transmission frequency set may be a frequency set determined by the vehicle key based on the second key request signal for outputting the second feedback signal, and the second transmission frequency set includes multiple different frequencies. The first transmission frequency set used by the first feedback signal is different from the second transmission frequency set used by the second feedback signal.

[0106] It can be understood that if the first feedback signal output using the first transmission frequency set is not received by the first RF transceiver component, it can be considered that there is interference in the environment in which the current vehicle and the vehicle key are located. Therefore, the second feedback signal is output using the second transmission frequency set to output the signal at a different frequency, thereby increasing the possibility that the second feedback signal can be received by the vehicle.

[0107] S105, outputting a second feedback signal using a second transmission frequency set;

[0108] In one embodiment, after the second feedback signal is generated and the second transmission frequency set is determined, each transmission frequency in the second transmission frequency set is used to poll and output the second feedback signal.

[0109] The second feedback signal includes multiple second feedback data packets, and the second transmission frequency set includes multiple transmission frequencies. Therefore, a feasible method for outputting the second feedback signal may be to use each frequency in the second transmission frequency set to poll and output each feedback data packet in the second feedback signal.

[0110] S106, if the second RF transceiver component receives a second feedback signal from the vehicle key within the second time period, verifying the key information in the second feedback signal and controlling the vehicle to start after the verification passes;

[0111] In one embodiment, when the second RF transceiver component receives a second feedback signal from the vehicle key within a second time period, the key information in the second feedback signal is verified according to the data in the second key request signal. After the second feedback signal is verified, instructions are transmitted to the relevant controllers of the vehicle to control the vehicle to complete startup.

[0112] The second time length can be a time length pre-set by the vehicle for waiting to receive the second feedback signal. It is understandable that by setting the second time length to limit the waiting time for the second feedback signal, unnecessary signal waiting is avoided, thereby improving the efficiency of vehicle startup.

[0113] After receiving the second feedback signal, the second RF transceiver component needs to verify the second feedback signal to determine that the second feedback signal is the feedback signal output by the vehicle key in response to the second key request signal. Exemplary methods for verifying the second feedback signal include parsing the second feedback signal to obtain key information, matching the key information with the information included in the second key request signal, and if the matching result indicates that the second feedback signal is the signal output by the vehicle key in response to the second key request signal, then determining that the second feedback signal has passed the verification. The key information can be

[0114] The relevant controller may be a controller of each component in the vehicle, and is used to control the components in the vehicle for performing functions such as starting and driving.

[0115] In an embodiment of the present application, the vehicle key outputs feedback signals multiple times using different transmission frequency sets. The vehicle determines that the vehicle key is near the vehicle based on the feedback signal output by the received vehicle key, and controls the vehicle start-up, thereby avoiding interference signals around the vehicle through different transmission frequency sets, thereby improving the reliability and stability of vehicle start-up.

[0116] Figure 3 The present invention provides a process sequence diagram of a vehicle starting method. Figure 3 As shown, the method of the embodiment of the present application may include the following steps S201-S214.

[0117] S201, in response to a start command for a vehicle, if a first radio frequency transceiver component of the vehicle does not receive a first feedback signal from a vehicle key within a first time period, controlling a second radio frequency transceiver component of the vehicle to output a second key request signal;

[0118] In one embodiment, the vehicle generates a start instruction after receiving a start operation performed by the user, and transmits the start instruction to a first radio frequency transceiver component of the vehicle. The first radio frequency transceiver component outputs a first key request signal in response to the start instruction.

[0119] The specific definitions of the start operation and the start instruction can be referred to the relevant content in step S101 and will not be repeated here.

[0120] The first RF transceiver component may be a component in the vehicle for outputting a RF signal to be paired with a vehicle key according to the RF signal. The vehicle key may be a device paired with the vehicle, including signal receiving and signal output functions.

[0121] The first key request signal can be a signal generated by the first radio frequency transceiver component to match the vehicle key. The first key request signal includes a first frequency indication identifier and a first request identifier. The first key request signal is used to determine whether the vehicle key is within the starting distance range of the vehicle. It can be understood that if the vehicle key is within the starting distance range, the vehicle key responds after receiving the first key request signal; if the vehicle key is not within the starting distance range, the vehicle key cannot receive the first key request signal. Therefore, the first key request signal can be used to determine whether the vehicle key is within the starting distance range of the vehicle. The specific value of the starting distance range can be set according to the signal receiving capability of the vehicle key.

[0122] The first request identifier may be an identifier generated by the first RF transceiver component based on the first request identifier of the first RF transceiver component. The first request identifier is included in the first key request signal and is used to identify the first key request signal. Since the first request identifier is generated based on the first request identifier, the first request identifier can not only be used to identify the first key request signal, but also can be used to determine whether it was generated by the first RF transceiver component.

[0123] The first component identifier may be an identifier of the first radio frequency transceiver component.

[0124] The first frequency indication identifier may be an identifier in the first key request signal used to indicate the frequency set used by the vehicle key, instructing the vehicle key to use the first transmission frequency set to output a signal.

[0125] Furthermore, the frequency used by the first radio frequency transceiver component to output the first key request signal may be a low frequency, for example, 125 kHz.

[0126] S202, in response to a first key request signal output by a first radio frequency transceiver component of the vehicle, parsing the first key request signal to obtain a first request identifier and a first frequency indication identifier;

[0127] In one embodiment, after receiving the first key request signal output by the first radio frequency transceiver component of the vehicle, the vehicle key performs parsing in response to the first key request signal to obtain a first request identifier and a first frequency indication identifier.

[0128] S203, generating a first feedback signal based on the first request identifier;

[0129] In one embodiment, a plurality of first feedback data packets are generated based on the first request identifier, and a first feedback signal is generated based on each first feedback data packet.

[0130] The first feedback signal can be a signal generated by the vehicle key in response to the first key request signal output by the first RF transceiver component. The first feedback signal includes multiple first feedback data packets, each of which contains a first signal identifier corresponding to the first request identifier. It should be noted that, to ensure that the vehicle can start after receiving the first feedback signal, each generated first feedback data packet is identical.

[0131] The first signal identifier may be an identifier used to indicate a signal in each first feedback data packet of the first feedback signal. Based on the first signal identifier, it is determined that the first feedback signal is a signal generated and output by the vehicle key in response to the first key request signal.

[0132] S204, determining a first transmission frequency set based on the first frequency indication identifier, using a first center frequency and a first microhop frequency of the first transmission frequency set, and polling and outputting first feedback data packets based on a second interval duration;

[0133] In one embodiment, the first transmission frequency set to be adopted is determined based on the first frequency indication identifier in the first key request signal, the first center frequency and the second micro-hop frequency of the first transmission frequency set are adopted, and each first feedback data packet in each first feedback signal is polled and output based on the second interval duration.

[0134] The first feedback packet may be a packet used to indicate that the vehicle key is within the vehicle's starting distance range. The first feedback packet may include data such as a first signal identifier and the time the packet was generated, and may also include a vehicle start permission instruction. It is understood that since the vehicle outputs the first key request signal to determine if the vehicle key is within the starting distance range, the presence of the vehicle start permission instruction in the first feedback packet is not a required instruction. Therefore, whether to include this instruction may be determined based on actual circumstances.

[0135] The second interval duration may be the duration between each first feedback data packet output by the vehicle key, for example, may be 5 ms, etc., and may be specifically set according to actual conditions.

[0136] The first transmission frequency set may be a frequency set for outputting the second feedback signal, determined based on the second frequency indicator. The first transmission frequency set includes a set of multiple frequencies, specifically a first center frequency and a first micro-hop frequency. The first center frequency may be a preset frequency, and the first micro-hop frequency may be a frequency that is relatively close to the first center frequency, for example, a frequency that is 0.5 MHz different from the first center frequency.

[0137] The first center frequency and the first micro-hop frequency may be different frequencies in the same frequency band. For example, if the first center frequency is 433.92 MHz, the first micro-hop frequencies may be 433.42 MHz and 434.42 MHz; and if the first center frequency is 314.92 MHz, the first micro-hop frequencies may be 314.42 MHz and 315.42 MHz.

[0138] Exemplarily, the process of polling and outputting each first feedback data packet may be as follows: Figure 4 As shown in the figure, the first first feedback data packet "Data Packet 1" is output at a frequency of 433.42 MHz, the second first feedback data packet "Data Packet 2" is output at a frequency of 433.92 MHz; the third first feedback data packet "Data Packet 3" is output at a frequency of 434.42 MHz; the fourth first feedback data packet "Data Packet 4" is output at a frequency of 433.42 MHz, until all first feedback data packets in the first feedback signal are output, and the time interval for outputting each first feedback data packet is the second interval duration.

[0139] S205, controlling the second radio frequency transceiver component of the vehicle to generate a second key request signal based on the second component identifier of the second radio frequency transceiver component;

[0140] In one embodiment, if the first RF transceiver component of the vehicle does not receive the first feedback signal from the vehicle key within a first time period, the second RF transceiver component of the vehicle is controlled to generate a second key request signal based on the second component identifier of the second RF component.

[0141] The specific definitions of the first duration, the first feedback signal, and the second radio frequency transceiver component may refer to the relevant content in step S103 and will not be repeated here.

[0142] The second frequency indication identifier may be an identifier in the second key request signal for indicating the frequency set used by the vehicle key, instructing the vehicle key to output a signal using the second transmission frequency set.

[0143] The second component identifier may be an identifier of the second radio frequency transceiver component, and is used to determine that the second key request signal is generated by the second radio frequency transceiver component.

[0144] The second key request signal may be a signal generated by the second radio frequency transceiver component to match the vehicle key. The second key request signal includes a second frequency indication identifier and a second request identifier of the second key request signal.

[0145] The second request identifier may be an identifier in the second key request signal for indicating a manner in which the vehicle key outputs a feedback signal.

[0146] For example, if the second component identifier is "component identifier 2" and the second frequency indicator identifier is "second micro-hopping set," the second request identifier can be formed by concatenating the second component identifier and the second frequency identifier via a connector, i.e., "component identifier 2 - second micro-hopping set." It will be appreciated that the second request identifier includes, in addition to the second component identifier and the second frequency indicator identifier, also signal generation time, etc., and these other contents are not presented here.

[0147] Furthermore, in the case where the first RF transceiver component and the second RF transceiver component are different transceiver components in the vehicle, if the first RF transceiver component does not receive the first feedback signal from the vehicle key within the first time period, the first RF transceiver component is controlled to generate a trigger signal and transmit the trigger signal to the second RF transceiver component.

[0148] The first RF transceiver component and the second RF transceiver component can perform output transmission through a wired connection to ensure the stability of data transmission between the first RF transceiver component and the second RF transceiver component.

[0149] The trigger signal may be generated by the first radio frequency transceiver component to instruct the second radio frequency transceiver component to generate the second key request signal. The trigger signal may be a level signal or other signal type.

[0150] S206, controlling the second radio frequency transceiver component to output a second key request signal;

[0151] In one embodiment, after the second RF transceiver component generates the second key request signal, the second RF transceiver component is controlled to output the second key request signal at a low frequency.

[0152] Furthermore, the frequency used by the second RF transceiver component to output the second key request signal may be the same as or different from the frequency used by the first RF transceiver component to output the first key request signal. For example, the first key request signal and the second key request signal may both be 125 kHz or 25 kHz.

[0153] It should be noted that the method in which the first RF transceiver component outputs the first key request signal and the second RF transceiver component outputs the second key request signal may be to output the signals through an antenna.

[0154] S207, parsing the second key request signal to obtain a second request identifier and a second frequency indication identifier, and generating a second signal identifier based on the second request identifier;

[0155] In one embodiment, after the vehicle key obtains the second key request signal, the second key request signal is parsed to obtain a second request identifier and a second frequency indication identifier, and a second signal identifier for marking the second feedback signal is generated based on the second request identifier.

[0156] The second signal identifier may be an identifier generated based on the second component identifier and the second frequency indication identifier in the second request identifier. Based on the second signal identifier, it can be determined that the second feedback signal is a signal generated by the vehicle key in response to the second key request information.

[0157] S208, generating a second feedback signal based on the second signal identifier;

[0158] In one embodiment, a plurality of second feedback data packets are generated based on the second signal identifier, and a second feedback signal is generated based on each second feedback data packet.

[0159] The second feedback packet may be a packet used to indicate that the vehicle key is within the vehicle's starting distance range. The second feedback packet may include data such as a second signal identifier and the time the packet was generated, and may also include a vehicle start permission instruction. It is understood that since the vehicle outputs the second key request signal to determine if the vehicle key is within the starting distance range, the presence of the vehicle start permission instruction in the second feedback packet is not a requirement. Therefore, whether to include this instruction may be determined based on actual circumstances.

[0160] The second feedback signal may be a signal generated by the vehicle key in response to the second key request signal output by the second RF transceiver component, wherein the second feedback signal includes a plurality of second feedback data packets, each of which includes a second signal identifier corresponding to the second request identifier.

[0161] It should be noted that, in order to enable the vehicle to start after receiving the second feedback signal, the generated second feedback data packets are identical.

[0162] S209, if the second frequency indication identifier is a micro-frequency hopping indication identifier, determine that the second transmission frequency set includes a second center frequency and a second micro-hopping frequency;

[0163] In one embodiment, the frequency set used to output the second feedback signal is determined based on the second frequency indication identifier in the second key request signal. If the second frequency indication identifier is a micro-frequency hopping indication identifier, it is determined that the second transmission frequency set includes the second center frequency and the second micro-frequency hopping frequency.

[0164] The micro frequency hopping identifier may be a frequency indication identifier in the second key request signal, used to indicate that a frequency set with a smaller frequency difference between frequencies is used as the second transmission frequency set.

[0165] The second center frequency may be a preset frequency, and the second micro-hop frequency may be a frequency close to the second center frequency, for example, 0.5 MHz apart, etc. The second frequency set may include one or more second micro-hop frequencies.

[0166] The second center frequency and the second micro-hop frequency are different frequencies in the same frequency band. For details, please refer to the relevant content of the first center frequency and the first micro-hop frequency in step S204. It should be noted that since the first feedback signal is not received by the vehicle when the first transmission frequency set is used to output the first feedback signal, it can be considered that there is signal interference in the environment where the vehicle is located when the first feedback signal is output. The second center frequency and the second micro-hop frequency are used to poll and output the second feedback signal, which can avoid the interference source that interferes with the first center frequency and the first micro-hop frequency from interfering with the output of the second feedback signal.

[0167] S210, if the second frequency indication identifier is a wide-band frequency hopping indication identifier, determining that the second transmission frequency set includes the second center frequency and the first center frequency in the first transmission frequency set;

[0168] In one embodiment, the second frequency indication identifier in the second key request signal may be a large-band frequency hopping indication identifier in addition to a micro-frequency hopping indication identifier. If the second frequency indication identifier is a large-band frequency indication identifier, it is determined that the second transmission frequency set includes the second center frequency and the first center frequency in the first transmission frequency set.

[0169] The second center frequency and the first center frequency are in different frequency bands. It should be noted that, because the vehicle's environment may contain interference sources that interfere with the first center frequency signal in addition to interference sources that interfere with the second center frequency, but the duration of the interference source is uncertain, the first and second center frequencies are used to poll and output the second feedback signal. This allows the second feedback signal to be smoothly output when the interference source stops interfering, thereby increasing the possibility of the vehicle starting.

[0170] S211: Use the second center frequency and the second microhop frequency to poll and output each second feedback data packet based on the first interval duration; or use the second center frequency and the first center frequency to poll and output each second feedback data packet based on the first interval duration;

[0171] In one embodiment, after determining the second transmission frequency set used by the second feedback signal according to the second frequency indication identifier in the second key request signal, each second feedback data packet in the second feedback signal is output using frequency polling in the second transmission frequency set.

[0172] Specifically, if the second sending frequency set includes a second center frequency and a second micro-hop frequency, the second center frequency and the second micro-hop frequency are used to poll and output each second feedback data packet based on the first interval duration; if the second sending frequency set includes a first center frequency and a second center frequency, the second center frequency and the first center frequency are used to poll and output each second feedback data packet based on the first interval duration.

[0173] The first interval duration may be the duration between each second feedback data packet output by the vehicle key, for example, 5 ms, etc. The first interval duration and the second interval duration may be the same or different, and may be set according to actual conditions.

[0174] The method of using the second transmission frequency set to poll and output each second feedback data packet can refer to the method of using the first transmission frequency set to poll and output each first feedback data packet in step S204, and will not be described in detail here.

[0175] It should be noted that when polling and outputting each first feedback data packet using the first transmission frequency set and polling and outputting each second feedback data packet using the second transmission frequency set, the frequencies used by each first feedback data packet and each second feedback data packet can be polled based on actual circumstances. For example, if the second transmission frequency set includes a second center frequency of 314.92 MHz and second microhop frequencies of 314.42 MHz and 315.42 MHz, the first second feedback data packet in the second feedback signal can be output using either a frequency of 314.42 MHz or the second center frequency.

[0176] S212, if the second RF transceiver component receives a second feedback signal from the vehicle key within the second time period, controlling the second RF transceiver component to analyze the second feedback signal to obtain a second signal identifier;

[0177] In one embodiment, if the second RF transceiver component of the vehicle receives the second feedback signal required by the vehicle within the second time period, the second RF transceiver component is controlled to parse the second feedback signal to obtain the second signal identifier in the second feedback signal.

[0178] The second time period may be a time period pre-set by the vehicle for waiting to receive the second feedback signal, for example, 2 seconds, etc. The specific values ​​of the first time period and the second time period may be the same value or different values, and may be set according to actual conditions.

[0179] The second feedback signal may be a feedback signal generated by the vehicle key in response to the second key request signal, and is used to indicate that the vehicle key has received the second key request signal and is within the starting distance range of the vehicle.

[0180] The second signal identifier may be an identifier for indicating a signal in the second feedback signal. The second signal identifier is matched with the second request identifier in the second key request signal to verify the second feedback signal.

[0181] S213, if the second signal identifier matches the second request identifier, determining that the second feedback signal passes verification, and controlling the vehicle to start;

[0182] In one embodiment, the second signal identifier in the second feedback signal and the second request identifier in the second key request signal are matched. If the second signal identifier matches the second request identifier, it is determined that the second feedback signal has passed the verification. After the second feedback signal passes the verification, instructions are transmitted to the relevant controllers of the vehicle to control the vehicle to complete the startup.

[0183] Exemplarily, the method for matching the second signal identifier and the second request identifier can be to compare the component identifier in the second signal identifier with the component identifier in the second request identifier, and to compare the frequency identifier in the second signal identifier with the frequency indication identifier in the second request identifier. If the comparison result is that the component identifier in the second signal identifier corresponds to the component identifier in the second request identifier, and the frequency identifier in the second signal identifier corresponds to the frequency indication identifier in the second request identifier, it can be determined that the second feedback signal has passed the verification.

[0184] For example, if the component identifier in the second signal identifier is "component identifier 2", which is the same as the component identifier "component identifier 2" in the second request identifier, and the frequency identifier in the second signal identifier is "micro-hopping 2", which corresponds to the "second micro-hopping set" in the frequency indication identifier in the second request identifier, then it is determined that the second feedback signal passes the verification.

[0185] The relevant controller may be a controller of each component in the vehicle, and is used to control the components in the vehicle for starting and driving functions, etc. For example, a command is transmitted to the controller of the engine or motor of the vehicle so that the controller enables the engine or motor to start working.

[0186] S214, if the second signal identifier does not match the second request identifier, determining that the second feedback signal fails verification;

[0187] In one embodiment, the second signal identifier in the second feedback signal is matched with the second request identifier in the second key request signal. If the second signal identifier does not match the second request identifier, it is determined that the second feedback signal has failed verification.

[0188] Exemplarily, if the second signal identifier and the second request identifier do not correspond, then the second signal identifier and the second request identifier are considered to be mismatched. For example, if the component identifier in the second signal identifier is "component identifier 2", which is the same as the component identifier "component identifier 2" in the second request identifier, and the frequency identifier in the second signal identifier is "large-band frequency hopping", which does not correspond to the "second micro-frequency hopping set" in the frequency indication identifier in the second request identifier, then it is determined that the second feedback signal has failed verification.

[0189] Furthermore, if the second feedback signal fails verification, a feasible method is for the second RF transceiver component to generate and output a new key request signal to perform multiple key requests. For key request signal output and feedback signal verification, refer to the output method of the first and second key request signals and the verification method of the second feedback signal.

[0190] Furthermore, if the second feedback signal fails verification, in addition to continuing the key request, a feasible method to reduce trial and error time is to confirm vehicle start and stop the key request. It is understandable that if the feedback signals of both key requests fail verification, it can be assumed that signal interference in the current vehicle environment caused the vehicle start failure. Therefore, stopping the key request can reduce unnecessary power consumption of the vehicle key.

[0191] Furthermore, in the case where the second RF transceiver component and the first RF transceiver component are different components, after the second feedback signal is verified, the second RF transceiver component is controlled to output a start signal to the first RF transceiver component, and the first RF transceiver component is controlled to transmit instructions to relevant controllers of the vehicle in response to the start signal to control the vehicle to complete startup.

[0192] The start signal can be a signal generated by the second RF transceiver component after the second feedback signal is verified to indicate that the vehicle key is detected. The start signal is transmitted to the first RF transceiver component through the wired connection between the first RF transceiver component and the second RF transceiver component.

[0193] Furthermore, if after the first RF transceiver component of the vehicle outputs the first key request signal, the first RF transceiver component receives a first feedback signal from the vehicle key within a first time period, the first RF transceiver component is controlled to parse the first feedback signal to obtain a first signal identifier, and the parsed first signal identifier is matched with the first request identifier in the first key request signal. If the first signal identifier and the first request identifier match, it is determined that the first feedback signal has passed the verification, and the vehicle is controlled to start.

[0194] The first signal identifier may be an identifier in the first feedback signal used to indicate a signal. Based on the first signal identifier, the first feedback signal is determined to be a signal generated and output by the vehicle key in response to the first key request signal. The first signal identifier is matched with the first request identifier in the first key request signal to verify the first feedback signal.

[0195] The first request identifier may be generated by the first radio frequency transceiver component based on the first component identifier of the first radio frequency transceiver component.

[0196] The matching method of the first signal identifier and the first request identifier and the method of controlling the vehicle startup can refer to the matching method of the second signal identifier and the second request identifier and the method of controlling the vehicle startup, which will not be repeated here.

[0197] It should be noted that the first frequency indication identifier and the second frequency indication identifier in the first key request signal and the second key request signal generated and output by the vehicle can be interchanged according to actual conditions, and thus the frequencies in the first transmitting frequency set and the second transmitting frequency set used by the vehicle key to output the first feedback signal and the second feedback signal can be switched according to actual conditions. For example, the second transmitting frequency set is used to output the first feedback signal, and the first transmitting frequency set is used to output the second feedback signal, etc., which can be specifically set according to actual conditions.

[0198] In an embodiment of the present application, the vehicle key outputs feedback signals multiple times using different transmission frequency sets. The vehicle determines that the vehicle key is in the vicinity of the vehicle based on the received feedback signals output by the vehicle key and controls vehicle startup. Interference signals around the vehicle are avoided by using different transmission frequency sets, thereby improving the reliability and stability of vehicle startup. Furthermore, a feedback signal is generated based on an identifier in the key request signal, and the transmission frequency set used is determined, thereby improving the accuracy and reliability of the feedback signal output by the vehicle key. Furthermore, based on the different conditions of the first RF transceiver component and the second RF transceiver component, corresponding methods are used to output the key request signal and receive and verify the feedback signal, thereby improving the versatility of vehicle startup when the RF components adopt different design methods.

[0199] Figure 5 The present invention provides a flow chart of a vehicle starting method. Figure 5 As shown, the method of the embodiment of the present application is applied to a vehicle, and the method may include the following steps S301-S302.

[0200] S301, in response to a start command for a vehicle, if a first radio frequency transceiver component of the vehicle does not receive a first feedback signal from a vehicle key within a first time period, controlling a second radio frequency transceiver component of the vehicle to output a second key request signal;

[0201] In one embodiment, the user starts the vehicle, and the vehicle's computer generates a start command after receiving the start operation, and transmits the start command to the vehicle's first RF transceiver component. The first RF transceiver component outputs a first key request signal in response to the start command. If the first RF transceiver component does not receive the first feedback signal from the vehicle key within a first time period, the second RF transceiver component of the vehicle is controlled to output a second key request signal.

[0202] The specific definitions of the start operation, the start instruction, the first radio frequency transceiver component and the first key request signal can be referred to the relevant content in step S101 and will not be repeated here.

[0203] The vehicle key may be a device paired with the vehicle, including signal receiving and signal output functions.

[0204] The first feedback signal may be a signal generated by the vehicle key in response to the first key request signal output by the first radio frequency transceiver component, and the frequency set used by the vehicle key to output the first feedback signal may be the first transmission frequency set.

[0205] The specific definitions of the first duration, the second radio frequency transceiver component, and the second key request signal may refer to the relevant content in step S103 and will not be repeated here.

[0206] S302, if the second RF transceiver component receives a second feedback signal from the vehicle key within the second time period, verifying the key information in the second feedback signal and controlling the vehicle to start after the verification passes;

[0207] In one embodiment, when the second RF transceiver component receives a second feedback signal from the vehicle key within a second time period, the key information in the second feedback signal is verified according to the data in the second key request signal. After the second feedback signal is verified, instructions are transmitted to the relevant controllers of the vehicle to control the vehicle to complete startup.

[0208] The second time period may be a time period preset by the vehicle for waiting to receive the second feedback signal.

[0209] The second feedback signal may be a signal generated by the vehicle key in response to the second key request signal. The frequency set used by the vehicle key to output the second feedback signal is a second transmission frequency set. The first transmission frequency set used by the first feedback signal and the second transmission frequency set used by the second feedback signal are different. The first transmission frequency set and the second transmission frequency set include multiple frequencies, each of which has frequencies in different frequency bands.

[0210] After receiving the second feedback signal, the second RF transceiver component needs to verify the second feedback signal to determine that the second feedback signal is the feedback signal output by the vehicle key in response to the second key request signal. Exemplary methods for verifying the second feedback signal include parsing the second feedback signal to obtain key information, matching the key information with the information included in the second key request signal, and if the matching result indicates that the second feedback signal is the signal output by the vehicle key in response to the second key request signal, then determining that the second feedback signal has passed the verification. The key information can be

[0211] The relevant controller may be a controller of each component in the vehicle, and is used to control the components in the vehicle for performing functions such as starting and driving.

[0212] In an embodiment of the present application, feedback signals output by the vehicle key multiple times using different transmission frequency sets are received, and the vehicle key is determined to be near the vehicle based on the feedback signal, and the vehicle start-up is controlled, thereby avoiding interference signals around the vehicle through different transmission frequency sets, thereby improving the reliability and stability of vehicle start-up.

[0213] The following will be combined Figure 6 A specific example of a vehicle starting method provided in an embodiment of the present application is described in detail, such as Figure 6 As shown, the method of the embodiment of the present application is applied to a vehicle, and the method may include the following steps S401-S412.

[0214] S401, in response to a start-up instruction for a vehicle, controlling a first radio frequency transceiver component of the vehicle to output a first key request signal;

[0215] In one embodiment, the vehicle generates a start instruction after receiving a start operation performed by the user, and transmits the start instruction to a first radio frequency transceiver component of the vehicle. The first radio frequency transceiver component outputs a first key request signal in response to the start instruction.

[0216] The specific definitions of the start operation and the start instruction can be referred to the relevant content in step S101 and will not be repeated here.

[0217] The first RF transceiver component may be a component in the vehicle for outputting a RF signal to be paired with a vehicle key according to the RF signal. The vehicle key may be a device paired with the vehicle, including signal receiving and signal output functions.

[0218] The first key request signal can be a signal generated by the first radio frequency transceiver component to match the vehicle key. The first key request signal includes a first frequency indication identifier and a first request identifier. The first key request signal is used to determine whether the vehicle key is within the starting distance range of the vehicle. It can be understood that if the vehicle key is within the starting distance range, the vehicle key responds after receiving the first key request signal; if the vehicle key is not within the starting distance range, the vehicle key cannot receive the first key request signal. Therefore, the first key request signal can be used to determine whether the vehicle key is within the starting distance range of the vehicle. The specific value of the starting distance range can be set according to the signal receiving capability of the vehicle key.

[0219] The first request identifier may be an identifier generated by the first RF transceiver component based on the first request identifier of the first RF transceiver component. The first request identifier is included in the first key request signal and is used to identify the first key request signal. Since the first request identifier is generated based on the first request identifier, the first request identifier can not only be used to identify the first key request signal, but also can be used to determine whether it was generated by the first RF transceiver component.

[0220] The first component identifier may be an identifier of the first RF transceiver component, used to mark the first RF transceiver component. Based on the first component identifier, it can be determined that the signal containing the first component identifier is generated or output by the first RF transceiver component.

[0221] The first frequency indication identifier may be an identifier in the first key request signal used to indicate the frequency set used by the vehicle key, instructing the vehicle key to use the first transmission frequency set to output a signal.

[0222] Furthermore, the frequency used by the first radio frequency transceiver component to output the first key request signal is a low frequency, for example, 125 kHz.

[0223] S402, controlling a second radio frequency transceiver component of the vehicle to generate a second key request signal based on a second component identifier of the second radio frequency transceiver component;

[0224] In one embodiment, if the first RF transceiver component of the vehicle does not receive the first feedback signal from the vehicle key within a first time period, the second RF transceiver component of the vehicle is controlled to generate a second key request signal based on the second component identifier of the second RF component.

[0225] The specific definition of the first feedback signal can refer to the relevant content in step S102, the specific definition of the first duration and the second RF transceiver component can refer to the relevant content in step S103, and the specific definition of the second frequency indication identifier, the second component identifier, the second key request signal and the second request identifier can refer to the relevant content in step S205, which will not be repeated here.

[0226] S403, controlling the second radio frequency transceiver component to output a second key request signal;

[0227] In one embodiment, after the second RF transceiver component generates the second key request signal, the second RF transceiver component is controlled to output the second key request signal at a low frequency.

[0228] Furthermore, the frequency used by the second RF transceiver component to output the second key request signal may be the same as or different from the frequency used by the first RF transceiver component to output the first key request signal. For example, the first key request signal and the second key request signal may both be 125 kHz or 25 kHz.

[0229] It should be noted that the method in which the first RF transceiver component outputs the first key request signal and the second RF transceiver component outputs the second key request signal may be to output the signals through an antenna.

[0230] S404, controlling the first radio frequency transceiver component to output a trigger signal to the second radio frequency transceiver component;

[0231] In one embodiment, when the first RF transceiver component and the second RF transceiver component are different transceiver components in the vehicle, if the first RF transceiver component does not receive the first feedback signal from the vehicle key within a first time period, the first RF transceiver component is controlled to generate a trigger signal and transmit the trigger signal to the second RF transceiver component.

[0232] The first RF transceiver component and the second RF transceiver component can perform output transmission through a wired connection to ensure the stability of data transmission between the first RF transceiver component and the second RF transceiver component.

[0233] The trigger signal may be generated by the first radio frequency transceiver component to instruct the second radio frequency transceiver component to generate the second key request signal. The trigger signal may be a level signal or other signal type.

[0234] It should be noted that if the first RF transceiver component and the second RF transceiver component are the same component, vehicle costs can be reduced, but the program implementation process corresponding to various scenarios must be considered when programming the components. If the first RF transceiver component and the second RF transceiver component are different components, when the first RF transceiver component does not receive the first feedback signal within the first time period, a trigger signal can be generated and transmitted to the second RF transceiver component, simplifying the program design process. Specific settings can be made based on actual conditions.

[0235] S405, controlling the second RF transceiver component to output a second key request signal in response to the trigger signal;

[0236] In one embodiment, after receiving the trigger signal, the second RF transceiver component controls the second RF transceiver component to respond to the trigger signal and proceed to execute steps S402 and S403 to generate and output the second key request signal. The generation and output process of the second key request signal is not described here.

[0237] S406, if the second RF transceiver component receives a second feedback signal from the vehicle key within the second time period, controlling the second RF transceiver component to analyze the second feedback signal to obtain a second signal identifier;

[0238] In one embodiment, if the second RF transceiver component of the vehicle receives the second feedback signal required by the vehicle within the second time period, the second RF transceiver component is controlled to parse the second feedback signal to obtain the second signal identifier in the second feedback signal.

[0239] The specific definitions of the second duration, the second feedback signal and the second signal identifier may refer to the relevant content in step S212 and will not be elaborated here.

[0240] It can be understood that after obtaining the second feedback signal, in order to ensure that the second feedback signal is a signal generated and output by the vehicle key in response to the second key request signal, the second feedback signal needs to be verified. Therefore, the second feedback signal is parsed to obtain the second signal identifier for verification.

[0241] S407, if the second signal identifier matches the second request identifier, determining that the second feedback signal passes verification, and controlling the vehicle to start;

[0242] In one embodiment, the second signal identifier in the second feedback signal and the second request identifier in the second key request signal are matched. If the second signal identifier matches the second request identifier, it is determined that the second feedback signal has passed the verification. After the second feedback signal passes the verification, instructions are transmitted to the relevant controllers of the vehicle to control the vehicle to complete the startup.

[0243] The specific process of verifying the second signal identifier and controlling the vehicle to start after the verification is passed can refer to the relevant content in step S213, which will not be repeated here.

[0244] S408, if the second signal identifier does not match the second request identifier, determining that the second feedback signal fails verification;

[0245] In one embodiment, the second signal identifier in the second feedback signal is matched with the second request identifier in the second key request signal. If the second signal identifier does not match the second request identifier, it is determined that the second feedback signal has failed verification.

[0246] The specific process of verifying the second signal identifier and making multiple key requests or stopping key requests when the verification fails can refer to the relevant content in step S214 and will not be repeated here.

[0247] It should be noted that if the second signal identification fails, re-requesting the key or stopping the key request can be set according to the actual situation, or the user can be provided with a selection operation after the vehicle is initialized, and the method to be adopted can be determined based on the user's selection operation.

[0248] S409, after the verification is passed, controlling the second RF transceiver component to output a start signal to the first RF transceiver component;

[0249] In one embodiment, when the second RF transceiver component and the first RF transceiver component are different components, after the second feedback signal passes verification, the second RF transceiver component is controlled to output a start signal to the first RF transceiver component.

[0250] The start signal can be a signal generated by the second RF transceiver component after the second feedback signal is verified to indicate that the vehicle key is detected. The start signal is transmitted to the first RF transceiver component through the wired connection between the first RF transceiver component and the second RF transceiver component.

[0251] S410, controlling the first radio frequency transceiver component to control the vehicle to start in response to the start signal;

[0252] In one embodiment, after the second RF transceiver component transmits the start signal to the first RF transceiver component, the second RF transceiver component controls the first RF transceiver component to transmit instructions to relevant controllers of the vehicle in response to the start signal, so as to control the vehicle to complete startup.

[0253] Among them, the specific starting steps can refer to the relevant content in step S213, which will not be repeated here.

[0254] S411, if the first radio frequency transceiver component of the vehicle receives a first feedback signal from the vehicle key within a first time period, controlling the first radio frequency transceiver component to parse the first feedback signal to obtain a first signal identifier;

[0255] In one embodiment, if the first RF transceiver component of the vehicle outputs the first key request signal and then receives a first feedback signal from the vehicle key within a first time period, the first RF transceiver component is controlled to parse the first feedback signal to obtain a first signal identifier.

[0256] The first feedback signal may be a signal generated by the vehicle key in response to the first key request signal output by the first RF transceiver component. The first transmission frequency set used by the first feedback signal is determined by the vehicle key based on the first frequency indication identifier in the first key request signal.

[0257] The first signal identifier may be an identifier in the first feedback signal used to indicate a signal. Based on the first signal identifier, the first feedback signal is determined to be a signal generated and output by the vehicle key in response to the first key request signal. The first signal identifier is matched with the first request identifier in the first key request signal to verify the first feedback signal.

[0258] S412, if the first signal identifier matches the first request identifier of the first key request signal, determining that the first feedback signal passes verification, and controlling the vehicle to start;

[0259] In one embodiment, the first signal identifier obtained by parsing is matched with the first request identifier in the first key request signal. If the first signal identifier and the first request identifier match, it is determined that the first feedback signal passes verification, and the vehicle is controlled to start.

[0260] The first request identifier may be generated by the first radio frequency transceiver component based on the first component identifier of the first radio frequency transceiver component.

[0261] The matching method of the first signal identifier and the first request identifier and the method of controlling vehicle startup can refer to the matching method of the second signal identifier and the second request identifier and the method of controlling vehicle startup in step S213, which will not be repeated here.

[0262] In an embodiment of the present application, feedback signals output by a vehicle key using different transmission frequency sets are received, and based on the feedback signals, the presence of the vehicle key in the vicinity of the vehicle is determined, thereby controlling vehicle startup. Interference signals present around the vehicle are avoided through different transmission frequency sets, thereby improving the reliability and stability of vehicle startup. Furthermore, by using corresponding methods to output the key request signal and receive and verify the feedback signal based on the different conditions of the first and second RF transceiver components, the versatility of vehicle startup is improved when the RF components adopt different design methods.

[0263] See Figure 7 , is a flow chart of a vehicle starting method provided in an embodiment of the present application. Figure 7 As shown, the method of the embodiment of the present application is applied to a vehicle key, and the method may include the following steps S501-S503.

[0264] S501, in response to a first key request signal output by a first radio frequency transceiver component of a vehicle, outputting a first feedback signal using a first transmission frequency set;

[0265] In one embodiment, after receiving a first key request signal output by a first radio frequency transceiver component of the vehicle, the vehicle key generates a first feedback signal in response to the first key request signal and outputs the first feedback signal using a first transmission frequency set.

[0266] The first key request signal is output by the first radio frequency transceiver component. The specific definitions of the first key request signal and the first radio frequency transceiver component can be referred to the relevant content in step S101 and will not be repeated here.

[0267] The first feedback signal may be a signal generated by the vehicle key in response to the first key request signal output by the first radio frequency transceiver component.

[0268] The specific definition of the first transmission frequency set may refer to the relevant content in step S204, which will not be described in detail here.

[0269] S502 , if a second key request signal is received, generating a second feedback signal in response to the second key request signal, and determining a second transmission frequency set based on the second key request signal;

[0270] In one embodiment, if a second key request signal is received after the first feedback signal is output, it is considered that the first feedback signal is not received by the first RF transceiver component of the vehicle, so a second feedback signal is output in response to the second key request signal, and a second transmission frequency set is determined based on the second key request signal.

[0271] The second feedback signal may be a signal generated by the vehicle key in response to the second key request signal. The second feedback signal includes a second signal identifier, so that the second RF transceiver component of the vehicle can verify the second feedback signal according to the second signal identifier.

[0272] The first feedback signal uses a first transmission frequency set that is different from the second transmission frequency set used by the second feedback signal. It is understood that if the first feedback signal is not received by the first RF transceiver assembly after being output using the first transmission frequency set, it can be assumed that interference exists in the environment surrounding the vehicle and the vehicle key. Therefore, the second feedback signal is output using the second transmission frequency set to increase the likelihood that the second feedback signal will be received by the vehicle.

[0273] S503, outputting a second feedback signal using a second transmission frequency set;

[0274] In one embodiment, after the second feedback signal is generated and the second transmission frequency set is determined, each transmission frequency in the second transmission frequency set is used to poll and output the second feedback signal.

[0275] The first transmission frequency set is different from the second transmission frequency set, the first key request signal is output by the first radio frequency transceiver component, and the second key request signal is output by the second radio frequency transceiver component of the vehicle.

[0276] Furthermore, the vehicle key outputs a second feedback signal, causing the vehicle to verify the second feedback signal and, if the verification is successful, start the vehicle. The specific process of the vehicle verifying the second feedback signal and starting the vehicle if the verification is successful can be found in step S106 and is not further described here.

[0277] In an embodiment of the present application, the vehicle key uses different transmission frequency sets to output feedback signals multiple times, so that the vehicle can determine that the vehicle key is near the vehicle based on the feedback signal output by the received vehicle key, and control the vehicle start-up, thereby avoiding the interference signals around the vehicle through different transmission frequency sets, thereby improving the reliability and stability of vehicle start-up.

[0278] The following will be combined Figure 8 A specific example of a vehicle starting method provided in an embodiment of the present application is described in detail, such as Figure 8 As shown, the method of the embodiment of the present application is applied to a vehicle key, and the method may include the following steps S601-S609.

[0279] S601, in response to a first key request signal output by a first radio frequency transceiver component of a vehicle, parsing the first key request signal to obtain a first request identifier and a first frequency indication identifier;

[0280] In one embodiment, after receiving the first key request signal output by the first radio frequency transceiver component of the vehicle, the vehicle key performs parsing in response to the first key request signal to obtain a first request identifier and a first frequency indication identifier.

[0281] The specific definitions of the first radio frequency transceiver component, the first key request signal, the first request identifier and the first frequency indication identifier can refer to the relevant content in step S201 and are not repeated here.

[0282] S602, generating a first feedback signal based on the first request identifier;

[0283] In one embodiment, a plurality of first feedback data packets are generated based on the first request identifier, and a first feedback signal is generated based on each first feedback data packet.

[0284] The first feedback signal can be a signal generated by the vehicle key in response to the first key request signal output by the first RF transceiver component. The first feedback signal includes multiple first feedback data packets, each of which contains a first signal identifier corresponding to the first request identifier. It should be noted that, to ensure that the vehicle can start after receiving the first feedback signal, each generated first feedback data packet is identical.

[0285] The first signal identifier may be an identifier used to indicate a signal in each first feedback data packet of the first feedback signal. Based on the first signal identifier, it is determined that the first feedback signal is a signal generated and output by the vehicle key in response to the first key request signal.

[0286] It should be noted that since there may be multiple vehicles in the environment where the vehicle is located that output key request signals at the same time, the first key request signal output by the vehicle that has a binding relationship with the vehicle key is determined by the first component identifier in the first request identifier, thereby avoiding responding to the key request signals output by other vehicles, wasting the power of the vehicle key, and possibly resulting in reduced response efficiency to the first key request signal.

[0287] S603: Determine a first transmission frequency set based on the first frequency indication identifier, use a first center frequency and a first microhop frequency of the first transmission frequency set, and poll and output first feedback data packets based on a second interval duration;

[0288] In one embodiment, the first transmission frequency set to be adopted is determined based on the first frequency indication identifier in the first key request signal, the first center frequency and the second micro-hop frequency of the first transmission frequency set are adopted, and each first feedback data packet in each first feedback signal is polled and output based on the second interval duration.

[0289] Among them, the specific determination of the first feedback data packet, the first sending frequency set and the second interval duration can refer to the relevant content in step S204, and the process of using the first sending frequency set to output each first feedback data packet in the first feedback signal can refer to the relevant content in step S204, which will not be repeated here.

[0290] S604, if a second key request signal is received, parsing the second key request signal to obtain a second request identifier and a second frequency indication identifier, and generating a second signal identifier based on the second request identifier;

[0291] In one embodiment, if the vehicle key receives a second key request signal after outputting a first feedback signal, it is considered that the first feedback signal has not been received by the vehicle, the second key request signal is parsed to obtain a second request identifier and a second frequency indication identifier, and a second signal identifier for marking the second feedback signal is generated based on the second request identifier.

[0292] The second signal identifier may be an identifier generated based on the second component identifier and the second frequency indication identifier in the second request identifier. Based on the second signal identifier, it can be determined that the second feedback signal is a signal generated by the vehicle key in response to the second key request information.

[0293] Exemplarily, if the second component identifier is "component identifier 2", the generated second signal identifier may include "component identifier 2" to indicate that the second signal identifier is an identifier generated in response to the second component identifier, and further indicate that the second feedback signal including the second signal identifier is a signal generated in response to the second component identifier.

[0294] Furthermore, after the vehicle outputs the second key request signal, it may also output other key request signals through the second RF transceiver component. However, labeling with the second component identifier alone cannot distinguish which key request signal the generated feedback signal is generated in response to. Therefore, the second signal identifier in each second feedback data packet may include, in addition to the second component identifier, a second frequency indicator identifier, thereby facilitating verification of the feedback signal by the second RF transceiver component. Furthermore, if the component identifier and frequency indicator identifier included in consecutively received key request signals are identical, a sequence number is added to the component identifier and frequency indicator identifier when generating the second signal identifier of the second feedback data packet, thereby distinguishing between identical component identifiers and frequency indicator identifiers.

[0295] For example, for key request signal 1 and key request signal 2 with the same component identifier and frequency indication identifier, the second signal identifier corresponding to "key request signal 1" can be "component identifier 2-second micro-frequency hopping set-request 1", and the second signal identifier corresponding to "key request signal 2" can be "component identifier 2-second micro-frequency hopping set-request 2".

[0296] Furthermore, a warning light may be provided on the vehicle key for flashing when the first key request signal and the second key request signal are received, thereby prompting the user that the vehicle key has received the first key request signal or the second key request signal.

[0297] S605: Generate a second feedback signal based on the second signal identifier, and determine a second transmission frequency set based on the second frequency indication identifier;

[0298] In one embodiment, multiple second feedback data packets are generated based on the second signal identifier, a second feedback signal is generated based on each second feedback data packet, and a second transmission frequency set used to output the second feedback signal is determined based on the second frequency indication identifier in the second key request signal.

[0299] The second feedback packet may be a packet used to indicate that the vehicle key is within the vehicle's starting distance range. The second feedback packet may include data such as a second signal identifier and the time the packet was generated, and may also include a vehicle start permission instruction. It is understood that since the vehicle outputs the second key request signal to determine if the vehicle key is within the starting distance range, the presence of the vehicle start permission instruction in the second feedback packet is not a requirement. Therefore, whether to include this instruction may be determined based on actual circumstances.

[0300] The second feedback signal can be a signal generated by the vehicle key in response to the second key request signal output by the second RF transceiver component. The second feedback signal includes multiple second feedback data packets, each of which contains a second signal identifier corresponding to the second request identifier. It should be noted that, to ensure that the vehicle can start after receiving the second feedback signal, each generated second feedback data packet is identical.

[0301] The second transmission frequency set may be a frequency set for outputting the second feedback signal, determined based on the second frequency indicator. The second transmission frequency set includes multiple transmission frequencies, each of which is different. Specifically, the second transmission frequency set may include the second center frequency and the second microhop frequency, or may include the second center frequency and the first center frequency of the second transmission frequency set.

[0302] S606: If the second frequency indication identifier is a micro-frequency hopping indication identifier, determine that the second transmission frequency set includes a second center frequency and a second micro-hopping frequency;

[0303] In one embodiment, if the second frequency indication identifier is a micro-frequency hopping indication identifier, the second transmission frequency set is determined to be a frequency set including the second center frequency and the second micro-frequency hopping frequency.

[0304] The specific definitions of the second center frequency and the second micro-hop frequency can be referred to step S209 and will not be described in detail here.

[0305] S607: Use the second center frequency and the second microhop frequency to poll and output each second feedback data packet based on the first interval duration;

[0306] In one embodiment, after determining that the second sending frequency set is a frequency set of a second center frequency and a second micro-hop frequency, the second center frequency and the second micro-hop frequency are used to poll and output each second feedback data packet in the second feedback signal based on the first interval duration.

[0307] Specifically, the method for the vehicle key to use the second center frequency and the second micro-hop frequency to poll and output each second feedback data packet based on the second interval duration can be to use the second center frequency or the second micro-hop frequency to output the second feedback data packet every first interval duration.

[0308] For example, the first second feedback data packet in the second feedback signal is outputted using the second center frequency, and after the first interval, the second second feedback data packet is outputted using the second micro-hop frequency until all the second feedback data packets in the second feedback signal are outputted. Figure 4 A method for outputting a first feedback signal.

[0309] The first interval duration may be the duration between each second feedback data packet output by the vehicle key, for example, 5 ms, etc. The first interval duration and the second interval duration may be the same or different, and may be set according to actual conditions.

[0310] It should be noted that when polling and outputting each first feedback data packet using the first transmission frequency set and polling and outputting each second feedback data packet using the second transmission frequency set, the frequencies used by each first feedback data packet and each second feedback data packet can be polled based on actual circumstances. For example, if the second transmission frequency set includes a second center frequency of 314.92 MHz and second microhop frequencies of 314.42 MHz and 315.42 MHz, the first second feedback data packet in the second feedback signal can be output using either a frequency of 314.42 MHz or the second center frequency.

[0311] S608: If the second frequency indication identifier is a wide-band frequency hopping indication identifier, determine that the second transmission frequency set includes the second center frequency and the first center frequency in the first transmission frequency set;

[0312] In one embodiment, if the second frequency indication identifier is a large-segment frequency indication identifier, it is determined that the second transmission frequency set includes the second center frequency and the first center frequency in the first transmission frequency set.

[0313] The second center frequency and the first center frequency are in different frequency bands. It should be noted that, because the vehicle's environment may contain interference sources that interfere with the first center frequency signal in addition to interference sources that interfere with the second center frequency, but the duration of the interference source is uncertain, the first and second center frequencies are used to poll and output the second feedback signal. This allows the second feedback signal to be smoothly output when the interference source stops interfering, thereby increasing the possibility of the vehicle starting.

[0314] S609: Use the second center frequency and the first center frequency to poll and output each second feedback data packet based on the first interval duration;

[0315] In one embodiment, after determining that the second sending frequency set is a frequency set of the second center frequency and the first center frequency, the second center frequency and the first center frequency are used to poll and output each second feedback data packet in the second feedback signal based on the first interval duration.

[0316] Specifically, the method of outputting each second feedback data packet using the first center frequency and the second center frequency may refer to the method of outputting each second feedback data packet in step S607, which will not be described in detail here.

[0317] It should be noted that the first transmission frequency set and the second transmission frequency set used by the vehicle key to output the first feedback signal and the second feedback signal can be set according to actual conditions, for example, the first feedback signal can be output using the second transmission frequency set.

[0318] Furthermore, if the vehicle key needs to output a third feedback signal after outputting the second feedback signal, the adopted transmission frequency set may be the first transmission frequency set or the second transmission frequency set, which may be specifically set according to actual conditions.

[0319] In an embodiment of the present application, the vehicle key repeatedly outputs feedback signals using different transmission frequency sets. This allows the vehicle to determine the key's proximity based on the received feedback signals and control vehicle startup. This avoids interference signals around the vehicle using different transmission frequency sets, thereby improving the reliability and stability of vehicle startup. Furthermore, the feedback signal is generated based on an identifier in the key request signal, and the transmission frequency set used is determined, further improving the accuracy and reliability of the feedback signal output by the vehicle key.

[0320] based on Figure 1 The system architecture will be combined with Figure 9 , the vehicle starting device provided by the embodiment of the present application is introduced in detail. It should be noted that, Figure 9 The vehicle starting device in the present application is used to execute Figure 2-Figure 6 For the convenience of explanation, only the part related to the embodiment of the present application is shown.

[0339] If the first signal identifier matches the first request identifier of the first key request signal, it is determined that the first feedback signal passes verification, and the vehicle is controlled to start. The first request identifier is generated by the first RF transceiver component based on the first component identifier of the first RF transceiver component.

[0340] In an embodiment of the present application, feedback signals output by the vehicle key using different transmission frequency sets are received, and based on the feedback signals, the presence of the vehicle key in the vicinity of the vehicle is determined, thereby controlling vehicle startup. Interference signals present around the vehicle are avoided through different transmission frequency sets, thereby improving the reliability and stability of vehicle startup. Furthermore, depending on the different conditions of the first and second RF transceiver components, corresponding methods are used to output the key request signal and receive and verify the feedback signal, thereby improving the versatility of vehicle startup under different RF component designs.

[0341] based on Figure 1 The system architecture will be combined with Figure 10 , the vehicle starting device provided by the embodiment of the present application is introduced in detail.

[0360] See Figure 11 , provides a structural diagram of a vehicle according to an embodiment of the present application. Figure 11 As shown, the vehicle 400 includes a processor 401 and a memory 402. The processor 401 is electrically connected to the memory 402.

[0361] Processor 401 is the control center of vehicle 400 and may include one or more processing cores. Processor 401 utilizes various interfaces and circuits to connect various components of vehicle 400. By running or invoking computer programs stored in memory 402 and accessing data stored in memory 402, it executes various functions of vehicle 400 and processes data, thereby providing overall control over vehicle 400. Optionally, processor 401 may be implemented using at least one of the following hardware forms: a digital signal processing (DSP), a field programmable gate array (FPGA), or a programmable logic array (PLA). Processor 401 may integrate one or a combination of a CPU, a graphics processing unit (GPU), and a modem. The CPU primarily processes the operating system, user interfaces, and applications; the GPU is responsible for rendering and drawing display content; and the modem handles wireless communications. It is understood that the modem may not be integrated into processor 401 and may instead be implemented via a separate communications chip.

[0362] Memory 402 can be used to store software programs and modules. Processor 401 executes various functional applications and data processing by running the computer programs and modules stored in memory 402. Memory 402 may primarily include a program storage area and a data storage area. The program storage area may store an operating system, computer programs required for at least one function, and the data storage area may store data generated based on the use of vehicle 400.

[0363] In addition, the memory 402 may include a high-speed random access memory and a non-volatile memory, such as at least one disk storage device, a flash memory device, or other volatile solid-state storage device. Accordingly, the memory 402 may also include a memory controller to provide the processor 401 with access to the memory 402.

[0364] In this embodiment, the processor 401 in the vehicle 400 loads instructions corresponding to one or more computer program processes into the memory 402 according to the following steps, and the processor 401 runs the computer program stored in the memory 402 to implement various functions as follows:

[0365] In response to a start-up command for the vehicle, if the first radio frequency transceiver component of the vehicle does not receive a first feedback signal from a vehicle key within a first time period, controlling the second radio frequency transceiver component of the vehicle to output a second key request signal;

[0366] If the second RF transceiver component receives a second feedback signal from the vehicle key within a second time period, verifying the key information in the second feedback signal and controlling the vehicle to start after the verification passes;

[0367] The first feedback signal is a signal generated by the vehicle key in response to the first key request signal output by the first radio frequency transceiver component, and the second feedback signal is a signal generated by the vehicle key in response to the second key request signal. The first transmission frequency set used by the first feedback signal is different from the second transmission frequency set used by the second feedback signal.

[0368] Optionally, when controlling the second radio frequency transceiver component of the vehicle to output the second key request signal, the processor 401 specifically performs:
