[0043] In order to make the objectives, technical solutions and advantages of this application more clear, this application is further described in detail below in combination with specific embodiments and with reference to the accompanying drawings.

[0045] It should be understood herein that any number of elements in the drawings is for illustration only and not for limitation, and any naming is only for distinction and does not have any limiting meaning.
[0046] Based on the description of the above background technology, the following situations also exist in the related art:
[0047] Low-frequency (LF) chips (typically operating at 125kHz or 134.2kHz) are key components of vehicle electronic systems, particularly in the Passive Entry Passive Start (PEPS) system. PEPS is an intelligent vehicle system based on radio frequency identification (RFID) technology that allows users to unlock doors and start the engine without a key. The PEPS system achieves keyless start through a three-pronged approach: low-frequency wakeup, high-frequency authentication, and location detection. The specific process is as follows:
[0048] When the user pulls the door handle or presses the start button, the PEPS main controller transmits a low-frequency signal (e.g., a low-frequency electromagnetic wave) through an LF antenna (125kHz or 134kHz) located in the vehicle door or interior. Low-frequency signals have strong penetration but a short transmission range (≤2 meters), making them suitable for centimeter-level positioning. The remote key, bound to the vehicle, contains a three-dimensional LF antenna. This LF signal is received through electromagnetic induction, generating a microcurrent that activates a passive RFID chip, activating the remote key. Once activated, the remote key locates the key by measuring the signal strength of the received LF signal. Simultaneously, the remote key transmits encrypted identification information, including a unique ID and rolling code, via a high-frequency RF signal (433MHz or 434MHz). The vehicle's RF receiver (typically located in the headliner) transmits this signal to the PEPS controller, which verifies whether the ID and rolling code match pre-stored data. If a match is found, high-frequency authentication is successful. When the user enters the vehicle and applies the brakes, the low-frequency chip locates the remote key inside the vehicle, successfully detecting its location and starting the vehicle.
[0049] When the vehicle's low-frequency chip fails, the RF start system may fail due to the inability to complete positioning or two-way authentication, but emergency start can be achieved through the backup mechanism. The low-frequency chip is responsible for accurately locating the position of the remote control key through the 125kHz signal. If the low-frequency chip fails, the vehicle cannot confirm whether the key is in the cockpit, and the system will reject the RF start command, resulting in the inability to start the vehicle. The low-frequency chip failure will also cause the two-way authentication to be interrupted. The low-frequency signal is used to wake up the key and trigger the RF response. When the low-frequency chip fails, the key cannot be activated, resulting in the inability to transmit the RF encryption signal (433MHz) back, the authentication process is interrupted, and the wireless start process fails.
[0050] In the related art, an anti-theft antenna unit is built into the vehicle's cup holder or steering column, and the remote control key is powered by electromagnetic induction within 5 cm (even if the LF chip is damaged, the key RFID chip can still work), directly driving the key to send an RFID authentication code to start the vehicle. That is, the remote control key is placed close to the anti-theft antenna mark position, and the anti-theft antenna stimulates the remote control key, causing the remote control key to send authentication information. The authentication information is transmitted to the engine control module through the CAN bus to realize the ignition start of the transmitter or motor. If the vehicle supports digital key start, the mobile phone NFC touch door handle or Bluetooth connection can be used to bypass the LF / RF authentication of the physical key and start the vehicle directly. However, not all vehicles support digital keys. A mechanical key can also be inserted into the keyhole to achieve emergency start. The above technical solutions all require the user to perform additional control operations, resulting in a poor user experience.
[0051] The vehicle startup control method, electronic device, and vehicle provided in the embodiments of the present application can determine the working state of the low-frequency chip based on the signal strength and operating temperature of the low-frequency chip; when the working state is an abnormal state, determine the emergency startup type based on the monitored startup control signal; if the emergency startup type is radio frequency signal startup, determine the signal monitoring result of the startup confirmation signal within a preset first time period, and determine the key detection result of the low-frequency chip for the remote control key, and perform vehicle startup control based on the key detection result and the signal monitoring result. A real-time preliminary evaluation of the state of the low-frequency chip is performed through signal strength and operating temperature. When the working state is an abnormal state, the low-frequency chip cannot operate normally, resulting in the vehicle being unable to start normally. At this time, it is necessary to determine the subsequent emergency startup strategy based on the emergency startup type. When the emergency startup type is radio frequency signal startup, it is determined through the key detection result that the user has a need to start the vehicle, and it is determined through the key detection result that the low-frequency chip has actually failed. At this time, the emergency startup of the vehicle is completed through the corresponding control strategy, avoiding the problem of the user being unable to start the vehicle and improving the user experience.
[0052] The vehicle startup control method provided by the embodiments of the present application is described in detail below with reference to the accompanying drawings.
[0053] In some embodiments, as Figure 1 As shown, a vehicle startup control method includes:
[0054] Step 101: Determine the working state of the low-frequency chip according to the signal strength and working temperature of the low-frequency chip.
[0055] In practice, low-frequency chip ablation refers to material melting or structural damage caused by overheating, overcurrent, or external energy injection, which has a multi-dimensional impact on chip performance, reliability, and system safety. Low-frequency chip ablation can cause abnormal electrical performance of the low-frequency chip, such as signal transmission interruption, drastic changes in noise characteristics, and abnormal power consumption.
[0056] After the low-frequency chip is ablated, the low-frequency signal emitted by the low-frequency chip will be interrupted. The ablation causes the metal wires of the low-frequency chip to melt or the solder joints to detach, and the signal path is interrupted, which manifests as a sudden drop in the signal strength of the low-frequency chip or returning to zero.
[0057] Ablation of a low-frequency chip can also dramatically alter the noise characteristics of the low-frequency signal emitted by the chip. This is because the ablated area can cause local arcing, generating high-frequency electromagnetic noise (>10kHz). This high-frequency electromagnetic noise can overwhelm the original low-frequency signal band, degrading the signal-to-noise ratio. Furthermore, the random conduction of the short-circuit point caused by ablation can introduce pulse glitches, interfering with normal data decoding and further degrading the signal-to-noise ratio.
[0058] Low-frequency chip ablation also leads to abnormal power consumption. After the metal layer melts, the resistance increases, the static current rises, and the power consumption of the low-frequency chip increases significantly (for example, the standby current rises from microamperes to milliamperes). Short-circuit points also cause a surge in leakage current, resulting in a significant increase in energy consumption.
[0059] Low-frequency chip ablation will also cause abnormal temperature of the low-frequency chip. During the low-frequency chip ablation process, the operating temperature of the low-frequency chip will experience four processes: slow rise → steep rise → explosion → slow fall. The slow rise process is the heat accumulation period. At this time, the operating temperature of the low-frequency chip is less than 300 degrees Celsius, and the local temperature difference is greater than 15 degrees Celsius. The metal in the low-frequency chip softens. At this time, the damage to the low-frequency chip is reversible, and ablation can be avoided by cooling.
[0060] The steep rise process corresponds to the critical period of heat. At this time, some materials in the low-frequency chip undergo phase change, and the temperature rises rapidly. The temperature rise rate is >5°C / ms. At this time, the temperature of the low-frequency chip rises rapidly, and the damage after the phase change is irreversible.
[0061] The explosion process corresponds to the heat explosion period. At this time, the metal material of the low-frequency chip is vaporized, the plasma arc discharges, and the temperature reaches the highest point, causing the silicon structure of the low-frequency chip to fail, the silicon lattice to collapse, the package to decompose, and the low-frequency signal to almost fail.
[0062] The slow-down process corresponds to the heat decay period. The heat slowly decreases, and the residual heat causes secondary aging of the low-frequency chip. At this time, the heat is still high.
[0063] As can be seen, the operating temperature is high throughout the entire low-frequency chip ablation process, so operating temperature can be used as a parameter to determine the low-frequency chip's condition. For electrical performance anomalies during the ablation process, signal strength and signal noise, which are the most easily monitored, can be used to determine the low-frequency chip's condition. When using noise signals to determine the low-frequency chip's condition, the primary focus is on flicker noise and recombination noise in the low-frequency signal. Flicker noise is low-frequency noise whose power spectral density is inversely proportional to frequency. Recombination noise is carrier concentration fluctuation noise caused by the random generation or recombination of carriers (electrons / holes) in the semiconductor. Flicker noise is an indicator of surface defects in low-frequency chips, while recombination noise is an indicator of internal defects. Therefore, if the percentage of flicker noise in the low-frequency signal is greater than or equal to a preset first noise threshold, the low-frequency chip is determined to have an external defect; if the percentage of recombination noise in the low-frequency signal is greater than or equal to a preset second noise threshold, the low-frequency chip is determined to have an internal defect. Therefore, if either an internal or external defect is determined, the low-frequency chip is considered to meet the signal anomaly condition. That is, when the proportion of flicker noise in the low-frequency signal is greater than or equal to a preset first noise threshold and / or the proportion of composite noise generated in the low-frequency signal is greater than or equal to a preset second noise threshold, it is determined that the low-frequency chip meets the signal abnormality condition.
[0064] Compared with noise signals, the working intensity of low-frequency signals is easier to measure, so the status of the low-frequency chip can be evaluated based on its signal intensity and working temperature. The determination process is shown in the following embodiment.
[0065] In some embodiments, determining the operating state of the low-frequency chip according to the signal strength and operating temperature of the low-frequency chip includes:
[0066] Step 1011: In response to the signal strength being less than or equal to a preset strength threshold, determining that a signal abnormality condition is met.
[0067] In specific implementations, when using signal strength and operating temperature to determine the operating status, abnormal low-frequency chip conditions (such as ablation) manifest themselves in electrical performance as a sudden drop in signal strength or zero, and in temperature as a sudden increase and loss of control. In the electrical performance evaluation dimension, a preset strength threshold is used to determine whether an electrical defect exists. The strength threshold needs to be set specifically based on the brand and type of low-frequency chip used in the vehicle. Generally, the corresponding strength threshold is calibrated at the factory. When determining electrical defects in the low-frequency chip, the strength threshold stored in the memory can be directly called.
[0068] After monitoring the signal strength of the low-frequency chip during operation, the signal strength is compared with the strength threshold. If the signal strength is less than or equal to the preset strength threshold, it indicates that the low-frequency chip has an abnormality that has caused the signal strength to decrease. It is determined that the low-frequency chip has an electrical performance abnormality and the signal abnormality condition is met. If the signal strength is greater than the preset strength threshold, it indicates that the signal strength of the low-frequency chip is within the normal range. It is determined that the low-frequency chip has no electrical performance abnormality and the signal abnormality condition is not met.
[0069] Among them, in order to avoid repeated jumps in the judgment results of the signal strength dimension, a hysteresis strategy can also be added. For example, taking the strength threshold as a and the hysteresis value as 0.05a, if the signal strength is 1.1a, it is determined that the signal anomaly condition is not met. When the signal strength drops to 0.98a, the judgment result of not meeting the signal anomaly condition is still maintained. Only when the signal strength drops directly below 0.95a, the judgment result is switched from not meeting the signal anomaly condition to meeting the signal anomaly condition. Similarly, if the signal strength is 0.9a, it is determined that the signal anomaly condition is met. When the signal strength rises to 1.03a, the judgment result of meeting the signal anomaly condition is still maintained. Only when the signal strength rises to above 1.05a, the judgment result is switched from meeting the signal anomaly condition to not meeting the signal anomaly condition. That is, when the signal strength is less than 0.95a, the signal anomaly condition is determined to be met, and when the signal strength is greater than 1.05a, the signal anomaly condition is determined to be not met. When the signal strength is between 0.95a and 1.05a, the original judgment result remains unchanged. As for the signal strength detected for the first time after the low frequency is started, the strength threshold a can be directly used for judgment.
[0070] Step 1012: In response to the operating temperature being greater than or equal to a preset temperature threshold, determining that a temperature anomaly condition is satisfied.
[0071] In practice, abnormal low-frequency chip conditions (e.g., ablation) manifest as sudden temperature increases and runaway temperatures. In the operating temperature assessment dimension, a preset temperature threshold is used to determine whether ablation risk exists. The intensity threshold needs to be set specifically based on the brand and type of low-frequency chip used in the vehicle. The corresponding temperature threshold is generally calibrated at the factory. When determining the ablation risk of a low-frequency chip, the temperature threshold stored in memory can be directly called.
[0072] After monitoring the operating temperature of the low-frequency chip, the operating temperature is compared with the temperature threshold. If the operating temperature is greater than or equal to the preset temperature threshold, it indicates that the operating temperature of the low-frequency chip has increased due to an abnormality such as ablation. The low-frequency chip is determined to be at risk of ablation and the temperature anomaly condition is met. If the operating temperature is less than the preset intensity threshold, the operating temperature of the low-frequency chip is within the normal required range. The low-frequency chip is determined to be not at risk of ablation and the temperature anomaly condition is not met.
[0073] To avoid repeated jumps in the judgment results for the operating temperature dimension, a hysteresis strategy can also be added. For example, taking the temperature threshold as b and the hysteresis value as 0.1b, if the operating temperature is 0.8b, the temperature anomaly condition is determined to be not met. When the operating temperature rises to 1.05b, the judgment result of not meeting the temperature anomaly condition remains. Only when the operating temperature rises and drops above 1.1b, the judgment result changes from not meeting the temperature anomaly condition to meeting the temperature anomaly condition. Similarly, if the operating temperature is 1.2b, the temperature anomaly condition is determined to be met. When the operating temperature drops to 0.95b, the judgment result of meeting the temperature anomaly condition remains. Only when the operating temperature drops below 0.9b, the judgment result changes from meeting the temperature anomaly condition to not meeting the temperature anomaly condition. That is, when the operating temperature is less than 0.9b, the temperature anomaly condition is determined to be not met, and when the operating temperature is greater than 1.1b, the signal anomaly condition is determined to be met. When the operating temperature is between 0.9b and 1.1b, the original judgment result remains unchanged. For the first monitored operating temperature after low-frequency startup, the temperature threshold b can be directly used for judgment.
[0074] Step 1013: In response to the signal abnormality condition and the temperature abnormality condition being satisfied simultaneously, determining the abnormal state as a working state.
[0075] In specific implementation, if both the abnormal signal conditions and the abnormal temperature conditions are met at the same time, it means that the electrical performance of the low-frequency chip has abnormally decreased while the operating temperature of the low-frequency chip has abnormally increased. It can be preliminarily assessed that there is a risk of ablation of the low-frequency chip, and the abnormal state can be determined as a working state.
[0076] If only the signal abnormality condition is met but the temperature abnormality condition is not met, it means that only the signal strength of the low-frequency chip has decreased. This may be caused by interference from environmental factors or abnormal power supply. Determine that the working status is normal and continue to monitor the signal strength.
[0077] If only the temperature abnormality condition is met but not the signal abnormality condition, it may be due to the influence of ambient temperature, resulting in a temporary temperature rise. In this case, the working state is determined to be normal and the signal strength monitoring can be continued. If a single abnormality condition is met for a long time, an alarm can be selected to prompt the user to perform maintenance.
[0078] If the signal abnormality condition and the temperature abnormality condition are not met, it means that the low-frequency chip is working normally, and the working state is determined to be normal.
[0079] Step 102: In response to the operating state being an abnormal state, determining an emergency start type according to a monitored start control signal.
[0080] During specific implementation, if the working status is abnormal, it means that the low-frequency chip can no longer operate normally, and the vehicle cannot confirm whether the key is in the cockpit. The system will reject the RF start command, resulting in the inability to start the vehicle. This is because the low-frequency chip failure will cause the two-way authentication to be interrupted. The low-frequency signal is used to wake up the key and trigger the RF response. When the low-frequency chip fails, the key cannot be activated, resulting in the inability to transmit the RF encrypted signal (433MHz) back, the authentication process is interrupted, and the RF start process fails.
[0081] If authentication fails, the vehicle may not emit a warning tone. If the user does not notice the lack of a warning tone, the user will not be aware that the low-frequency chip is no longer functioning and will continue with the RF startup process. If the user notices the lack of a warning tone, it indicates that the user has determined that there is a problem with the vehicle startup. In this case, the user may actively perform an emergency start operation to start the vehicle. Therefore, after the low-frequency chip fails, it is necessary to determine the emergency start type used by the user based on the monitored startup control signal. The determination process is shown in the following embodiment.
[0082] In some embodiments, determining the emergency start type according to the monitored start control signal includes:
[0083] Step 1021 : In response to the start control signal including a radio frequency signal for unlocking the vehicle door, determining the radio frequency signal start as an emergency start type.
[0084] In specific implementations, a malfunction of the low-frequency chip will not affect the ability to unlock the door by pressing the remote key's unlock button (RF remote control). The low-frequency chip's main function is positioning and waking up the remote key. The low-frequency chip drives the interior / exterior antenna to transmit a low-frequency signal (125kHz) to wake up the remote key and accurately locate the remote key. This signal is used to determine whether the remote key is inside or outside the vehicle. The vehicle can only be started when the remote key is inside. If the low-frequency chip is damaged, the vehicle will not be able to wake up the remote key or detect its location through the low-frequency signal, resulting in the failure of the keyless start function.
[0085] The remote key's unlock button is independently controlled. When the user presses the unlock button, the remote key's driver chip communicates directly with the vehicle's Central Electronic Module (CEM) by sending high-frequency radio frequency signals (433MHz or 434MHz), without relying on a low-frequency chip. This means that key unlocking is functionally independent. RF signal remote unlocking is a one-way communication from the remote key to the vehicle, separate from the two-way location authentication during the startup process. As long as the remote key's RF transmitter and the vehicle's RF receiver are functioning properly, pressing the unlock button will trigger the door unlocking.
[0086] If the user does not notice that the vehicle does not emit a two-way authentication prompt tone or the user knows about the automatic emergency start function in advance, as long as the user uses the unlock button of the remote control key to unlock the car door, the key will send a radio frequency signal to the vehicle for unlocking the door. After the vehicle's body domain controller receives the radio frequency signal, it can be confirmed that the user has the need to enter the vehicle and start the vehicle. At this time, the user does not need to perform additional control operations. The user only needs to perform the start control according to the conventional start control method to automatically complete the emergency start control. When the start control signal includes the radio frequency signal for unlocking the car door, the automatically activated radio frequency signal start is determined as the emergency start type.
[0087] The automatically activated RF signal start-up method will be restricted by conventional start-up actions when starting the vehicle. For example, if the user enters the car and steps on the brakes, if the user enters the car and does not perform the corresponding control action within a certain period of time, the automatically activated RF signal start-up will be automatically terminated. At this time, the user must actively use the remote control key again to transmit the RF signal to reactivate the emergency start-up strategy of RF signal activation. For example, by pressing the remote control combination button of the remote control key (such as the start button or the lock + car search button) to transmit a high-frequency RF signal. Each emergency start-up strategy activated by the RF signal is subject to the time and brake start-up action restrictions. By setting the time display, it is possible to avoid being in emergency start mode for a long time, reduce interference with other conventional control processes, avoid control conflicts, and ensure user experience.
[0088] Step 1022: In response to the start control signal being a manual control signal, determining the active control start as an emergency start type, wherein the manual control signal is issued when the user performs a preset active emergency start control operation.
[0089] In specific implementation, in order to provide users with a more proactive emergency start control strategy, users are allowed to implement emergency start in the event of a low-frequency chip failure through pre-set proactive emergency start control operations. For example, when the power mode is OFF, the user can trigger the start flag setting by long-pressing the remote key unlock button for 10 seconds, making the vehicle sensitive to the start operation within 11 seconds. At the same time, during the start process, the validity of the low-frequency chip fault flag is maintained within 11 seconds to ensure startup safety. When the user executes the pre-set proactive emergency start control operation, a manual control signal will be sent to the vehicle body domain controller. At this time, it can be determined that the user has adopted an proactive control method to achieve emergency start, and the proactive control start will be determined as the emergency start type. Among them, the pre-set proactive emergency start control operation can also be used by the user to insert a mechanical key into the keyhole for startup control.
[0090] In the event of a low-frequency chip failure, the introduction of an RF signal startup type that automatically activates and triggers the system reduces the risk of startup failure due to faults and enhances system stability. The implementation of active control startup technology not only provides a new startup method but also improves the fault detection mechanism before and after startup, improving vehicle startup safety. This reduces user waiting time and improves startup efficiency during fault conditions.
[0091] Step 103: In response to the emergency start type being radio frequency signal start, determine the signal monitoring result of the start confirmation signal within a preset first time period, determine the key detection result of the low-frequency chip on the remote control key, and perform vehicle start control based on the key detection result and the signal monitoring result.
[0092] In specific implementation, if the emergency start type is automatically activated radio frequency signal start, the user's control habits will not be changed during the start process, so it is necessary to detect whether the user has executed the control action of the two-way authentication start process, that is, to determine the signal monitoring result of the start confirmation signal within the preset first time period, wherein the start confirmation signal is the signal generated by the user performing the corresponding action during the start process, such as the brake stepping signal. At the same time, before starting, further verify whether the low-frequency chip has really failed, and verify it by determining the key detection result of the low-frequency chip on the remote control key. If the key detection result sent by the low-frequency chip can still be received, it means that the low-frequency chip has no fault and can still operate. It only needs to issue a fault alarm to inform the user that there may be an abnormality in the low-frequency signal. If the key detection result sent by the low-frequency chip cannot be received, it means that the low-frequency chip has stopped working, and emergency start can only be performed based on the key detection result and signal monitoring result.
[0093] In summary, the vehicle startup control method provided in the present application can perform a real-time preliminary evaluation of the status of the low-frequency chip through signal strength and operating temperature. When the working state is abnormal, the low-frequency chip cannot operate normally, resulting in the vehicle being unable to start normally. At this time, it is necessary to determine the subsequent emergency startup strategy based on the emergency startup type. When the emergency startup type is radio frequency signal startup, the key detection result is used to determine whether the user has the need to start the vehicle. The key detection result is used to determine that the low-frequency chip has actually failed. At this time, the emergency startup of the vehicle is completed through the corresponding control strategy, avoiding the problem of the user being unable to start the vehicle and improving the user experience.
[0094] In some embodiments, as Figure 2 As shown, determining the signal monitoring result of the start confirmation signal within the preset first time period includes:
[0095] Step 201: In response to detecting a start confirmation signal within a first time period, determining the presence of a start requirement as a signal monitoring result.
[0096] During specific implementation, the preset first time period is an estimate of the time it takes for the user to unlock the car door and confirm the driving process. Since the emergency start control activated by the radio frequency signal will be automatically activated after the user sends the radio frequency signal, in order to ensure control safety, it cannot be guaranteed that the emergency start control will remain activated all the time. Because the radio frequency signal transmitted by the user itself has a certain control effect, it is not a complete emergency start. Therefore, in order to avoid conflicts between the emergency start control and other controls, the duration of the automatic emergency start activation state is limited by the preset first time period. For example, take the first time period of 30 seconds as an example. 30 seconds is approximately the total time it takes for the user to press the unlock button of the remote control key, unlock the car door, walk to the car door, open the door to enter the vehicle, and step on the brake to start the vehicle.
[0097] If a start confirmation signal is detected within the first time period, it indicates that the user has fully and promptly executed the brake-confirming start action. After the user completes the start confirmation action, the body domain controller detects the start confirmation signal, confirms that the user has a start request, and identifies the start request as a signal monitoring result. At this point, the two-way authentication process can be skipped, and the RF signal can be directly converted into a low-frequency analog signal based on the emergency start request. The vehicle start is then controlled based on the low-frequency analog signal, achieving automatic emergency start after the low-frequency chip is damaged.
[0098] Step 202: In response to not detecting a start confirmation signal within a first time period, determining that no start requirement exists as a signal monitoring result.
[0099] During specific implementation, if the start confirmation signal is not detected within the first time period, it means that the user did not perform the confirmation start action of stepping on the brake in time, and the body domain controller will not be able to detect the start confirmation signal, and it is determined that the user does not have the need to start the vehicle temporarily, and the start demand is determined as the signal monitoring result. The emergency start control state is automatically turned off after the activation state lasts for 30 seconds. When the emergency start control state is turned off, if the user does not activate the emergency start state again, the emergency start cannot be achieved. The emergency start state is limited in time dimension by the first time period to avoid conflicts between the long-lasting emergency start state and other control processes, thereby ensuring control safety.
[0100] In some embodiments, as Figure 3 As shown, the key detection result of the low-frequency chip on the remote control key is determined, including:
[0101] Step 301 : In response to not detecting a key position signal within a preset second time period, determining a detection failure as a key detection result.
[0102] In specific implementations, when determining a user's start request, further verification of the low-frequency chip's status is required. If the low-frequency chip is not faulty, the start process includes the user entering the vehicle, pressing the brake, pressing the start button, the low-frequency antenna scanning the remote key, unlocking the steering column and fuel supply circuit after authentication, and then igniting the engine. A low-frequency chip failure can interrupt the low-frequency antenna scanning process. The low-frequency antenna transmits low-frequency electromagnetic waves to accurately locate the key, which takes a certain amount of time. During the positioning process, multiple low-frequency antennas are deployed on the vehicle side, distributed in locations such as the doors, interior, and trunk, forming magnetic fields covering different areas. When the user triggers the start operation, the antennas in the corresponding areas transmit 125kHz low-frequency signals, waking up the three-dimensional receiving coils (X / Y / Z axes) in the key, ensuring that the low-frequency signal can be received at any angle. The distance between the remote key and each low-frequency antenna is calculated based on the attenuation of the magnetic field strength (RSSI value). The body domain controller compares the signal strengths of multiple antennas and accurately locates the remote key through triangulation or a polling switching strategy. The vehicle starts when the remote key is inside the vehicle.
[0103] It takes a certain amount of time to determine the key position through the low-frequency signal, and the preset second time period is the theoretical maximum time for the low-frequency signal to determine the key position, for example 2.5s. If the key position signal is not detected within the preset second time period, it means that the low-frequency chip has indeed failed, causing the low-frequency antenna to fail and unable to complete the key positioning, indicating that the working status has passed the verification, and the detection failure is determined as the key detection result.
[0104] Step 302 : In response to detecting the key position signal within a preset second time period, determining a successful detection as a key detection result.
[0105] During specific implementation, if the key position signal is monitored within the preset second time period, it means that the low-frequency chip has not failed and can still drive the low-frequency antenna to work and complete key positioning, which means that the working status has not passed the verification and the successful detection is determined as the key detection result.
[0106] The true status of the low-frequency signal is verified through the key detection result to avoid unnecessary emergency start control caused by misjudgment.
[0107] In some embodiments, as Figure 4 As shown, vehicle startup control is performed based on the key detection result and signal monitoring result, including:
[0108] Step 401: In response to the signal monitoring result indicating that a start request exists and the key detection result indicating a detection failure, converting the radio frequency signal into a low-frequency analog signal, and controlling vehicle start according to the low-frequency analog signal;
[0109] In specific implementations, if the signal monitoring result indicates a start request, the user needs to start the vehicle. Meanwhile, if the key detection result indicates a failure, it indicates a fault with the low-frequency chip, requiring emergency start to start the vehicle. At this point, the RF signal is converted to a low-frequency analog signal, and a high-frequency communication link is used to replace the failed low-frequency positioning function. This is combined with the vehicle's backup authentication mechanism to complete the start control.
[0110] For example, the user presses the unlock button of the remote control key, and the remote control key sends a high-frequency RF signal. The body domain controller mixes the RF signal with LO through the internal high-frequency to low-frequency signal conversion device (such as a mixer) to generate a 125kHz initial low-frequency signal. The initial low-frequency signal is filtered and amplified to obtain a low-frequency analog signal. The low-frequency analog signal is used to drive the multiplexed antenna, and the multiplexed antenna transmits an analog low-frequency signal to activate the low-frequency receiver in the remote control key. After the remote control key is activated, it transmits a radio frequency authentication signal. After the vehicle verifies the radio frequency authentication signal, it unlocks and ignites, completing the emergency start.
[0111] Step 402: In response to the signal monitoring result indicating that there is no start-up demand, the process returns to the step of determining the emergency start-up type according to the monitored start-up control signal.
[0112] During specific implementation, if the signal monitoring result shows that there is no start-up requirement, it means that the user has not performed the corresponding start-up control operation. After the first time period ends, the emergency start-up control state ends, and it can only return to the step of determining the emergency start-up type based on the monitored start-up control signal, and re-monitor the emergency start-up control to avoid the vehicle failing to respond when the user uses the emergency start-up control.
[0113] Step 403 : In response to the signal monitoring result indicating that there is a start requirement and the key detection result indicating that the key is detected successfully, the vehicle is started according to the low-frequency start signal.
[0114] In specific implementation, if the signal monitoring result shows that there is a start demand and the key detection result is a successful detection, it means that the working status of the low-frequency signal is a misjudgment, and there is no need for emergency start control. The key can be located directly according to the low-frequency signal. When the key is inside the vehicle, the vehicle can be started.
[0115] In some embodiments, as Figure 5 As shown, the vehicle startup control method further includes:
[0116] Step 501: In response to the emergency start type being active control start, the abnormal state is locked according to a preset first duration, and the duration of the active control operation is determined.
[0117] In specific implementation, if the emergency start type is active control start, the abnormal state is locked according to the preset first duration to ensure that the emergency start process will not be terminated due to a sudden change in the evaluation of the low-frequency chip status. For example, when the power mode is OFF, the user triggers the active control start by pressing and holding the remote key unlock button for 10 seconds, making the vehicle sensitive to the start operation within 11 seconds. The abnormal state is locked for 11 seconds, and the validity of the low-frequency chip fault flag is maintained within 11 seconds to ensure startup safety. The first duration corresponds to 10 seconds, which is greater than the second duration corresponding to 11 seconds. When the user executes the pre-set active emergency start control operation, a manual control signal will be sent to the vehicle body domain controller. At this time, it can be determined that the user uses active control to achieve emergency start, and the active control start is determined as the emergency start type. The preset active emergency start control operation can also be a start control for the user by inserting a mechanical key into the keyhole.
[0118] Step 502: In response to the duration being greater than or equal to a preset second duration, converting the start control signal into a low-frequency analog signal and controlling the vehicle to start according to the low-frequency analog signal, wherein the first duration is greater than the second duration.
[0119] In specific implementation, if the duration is greater than or equal to the preset second duration, it means that the user really wants to activate the emergency start function, the start control signal is converted into a low-frequency analog signal, and the vehicle start is controlled according to the low-frequency analog signal.
[0120] In the event of a low-frequency chip failure, the introduction of an RF signal startup type that automatically activates and triggers the system reduces the risk of startup failure due to faults and enhances system stability. The implementation of active control startup technology not only provides a new startup method but also improves the fault detection mechanism before and after startup, improving vehicle startup safety. This reduces user waiting time and improves startup efficiency during fault conditions.
[0121] In some embodiments, the vehicle startup control method further includes:
[0122] In response to not detecting the start confirmation signal within the first time period, the method returns to the step of determining the emergency start type according to the detected start control signal.
[0123] During specific implementation, if the start confirmation signal is not detected within 30 seconds, it means that the user does not have the need to start the vehicle when activating the emergency control state this time. Return to the step of determining the emergency start type based on the monitored start control signal, and re-monitor to ensure timely response to the emergency start control.
