[0033] See also Figure 2 , Figure 2 A flow chart of a vehicle control method proposed according to an embodiment of the present application is shown, which is used for a vehicle, and the method includes:

[0034] S110, obtaining the ignition status information of the vehicle and the usage mode detection result corresponding to the usage mode.

[0035] The vehicle in this embodiment can be an electric vehicle or a fuel vehicle, or a sedan, an SUV, a bus, a truck, etc.; the self-vehicle refers to the vehicle itself.

[0036] The use mode of the vehicle is used to indicate the working state of the vehicle, and the use mode may include standby mode, comfort mode and driving mode. The standby mode refers to the mode in which the vehicle is in standby state. In standby mode, the vehicle is powered on but not ignited, and each controller in the vehicle is in a dormant state; the comfort mode refers to the mode in which the vehicle is powered on but not ignited, and the vehicle provides a comfortable experience according to instructions, such as providing music playing services, seat massage services, air conditioning services, and video playing services; the driving mode refers to the state in which the vehicle is in driving state, which may be the vehicle driving along the road, reversing, overtaking, and changing lanes, etc.

[0037] The usage mode detection result is the result obtained by detecting the usage mode of the vehicle. The usage mode detection result is used to indicate a specific usage mode or whether a usage mode is detected. The usage mode detection result can be in the form of numbers, letters or text. For example, the usage mode detection result is 0, indicating that the usage mode is standby mode. The usage mode detection result is 1, indicating that the usage mode is comfort mode. The usage mode detection result is 3, indicating that the usage mode is driving mode. For example, the usage mode detection result is 4, indicating that no usage mode is detected (it may be that the signal indicating the usage mode is lost or the signal indicating the usage mode has data loss, etc.).

[0038] The ignition status information is used to indicate whether the vehicle is in the ignition state or the flameout state. The ignition status information can be in the form of numbers, letters or text. For example, the ignition status information is 1, indicating that the vehicle is in the ignition state, and the ignition status information is 0, indicating that the vehicle is in the flameout state.

[0039] In some embodiments, the ignition status information of the vehicle can be determined directly through the usage mode. For example, when the usage mode of the vehicle is standby mode or comfort mode, it is determined that the vehicle is in the off state, and the ignition status information indicates that the vehicle is in the off state. For another example, when the usage mode of the vehicle is driving mode, it is determined that the vehicle is in the ignition state, and the ignition status information indicates that the vehicle is in the ignition state.

[0040] In yet other implementations, the ignition status of the vehicle may be directly detected to determine the ignition status information.

[0041] S120: Acquire auxiliary detection information based on the ignition state information.

[0042] According to the specific ignition status information of the own vehicle, a supplementary basis for determining the ignition control signal of the own vehicle, namely, auxiliary detection information, is determined.

[0043] In the present application, when the ignition status information indicates that the vehicle is in the off state, the auxiliary detection information includes the brake pedal status information of the vehicle's brake pedal; when the ignition status information indicates that the vehicle is in the ignition state, the auxiliary detection information includes the port status information of the vehicle's signal output port.

[0044] That is to say, when the vehicle is off, the brake pedal status information of the vehicle's brake pedal is obtained as auxiliary detection information, wherein the brake pedal status information is used to indicate whether the brake pedal is pressed. The brake pedal status information can be in the form of numbers, letters or text. For example, the brake pedal status information is 1, indicating that the brake pedal is pressed. For another example, the brake pedal status information is 0, indicating that the brake pedal is not pressed.

[0045] When the vehicle is in the ignition state, the port status information of the signal output port of the vehicle is obtained as auxiliary detection information, wherein the port status information is used to indicate the working state of the signal output port, and the working state of the signal output port may include a normal state, a short-circuit state to ground, a short-circuit state to electricity, an open circuit state and an overload state, and the port status information may be in the form of numbers, letters or text; for example, the port status information is 0, indicating that the signal output port is in a normal state, the port status information is 1, indicating that the signal output port is in a short-circuit state to ground, the port status information is 2, indicating that the signal output port is in a short-circuit state to electricity, the port status information is 3, indicating that the signal output port is in an open circuit state, and the port status information is 4, indicating that the signal output port is in an overload state.

[0046] S130: Determine an ignition control signal of the vehicle according to the usage mode detection result and / or the auxiliary detection information.

[0047] The ignition control signal may include an ignition signal and an ignition off signal; after determining the usage mode and auxiliary detection information, the ignition control signal may be determined based on the usage mode detection result, or based on the auxiliary detection information, or may be determined based on both the usage mode detection result and the auxiliary detection information.

[0048] In some embodiments, if the ignition status information indicates that the vehicle is in an off state, S130 may include: if the brake pedal status information indicates that the brake pedal is pressed, and the usage mode detection result indicates that no usage mode is detected, based on the key authentication status information of the vehicle, the air download mode information and the port status information of the signal output port, determine the ignition control signal of the vehicle.

[0049] In the present application, the key authentication status information is used to indicate the authentication status of the key of the vehicle. The key authentication status information can be in the form of text, numbers or letters; for example, the key authentication status information is 0, indicating that the key authentication is undefined, the key authentication status information is 1, indicating that the key authentication has not passed, the key authentication status information is 2, indicating that the key authentication has passed, and the key authentication status information is 3, indicating that the key authentication is busy.

[0050] Over-the-Air Technology (OTA) mode information is used to indicate whether the vehicle is in OTA mode. The OTA mode information may be in the form of text, letters or numbers. For example, the OTA mode information is 0, indicating that the vehicle is not in OTA mode. The OTA mode information is 0, indicating that the vehicle is in OTA mode. When the vehicle is in OTA mode, the vehicle obtains data (including firmware upgrade packages, vehicle data and remote commands, etc.) based on OTA technology.

[0051] Specifically, when the brake pedal status information indicates that the brake pedal is depressed, and the use mode detection result indicates that no use mode is detected, if the key authentication status information satisfies the key authentication status change mode, the port status information indicates the preset port status, and the air download mode information indicates that the vehicle is in the non-air download mode, the ignition control signal is determined to be an ignition signal, otherwise, the ignition control signal is not generated, that is, the vehicle is kept in the off state. Among them, the key authentication status change mode includes any one of the following: from undefined key authentication to key authentication passed, from key authentication failed to key authentication passed, and from key authentication busy to key authentication passed; the preset port status includes normal state, circuit state, and open state.

[0052] When the numbers in the above examples are used to indicate different states, the above determination means are shown in Table 1, which is as follows:

[0053] Table 1

[0054]

[0055]

[0056] Among them, the ignition control signal is 1, indicating that the ignition control signal is an ignition signal, and the ignition control signal is 0, indicating that the ignition control signal is an off signal; the brake pedal status information 0-1 indicates that the brake pedal is pressed.

[0057] In some other embodiments, when the ignition status information indicates that the vehicle is in the off state, S130 may also include: when the usage mode indicates that the vehicle is in the comfort mode, the vehicle has not requested automatic parking, and the brake pedal status information indicates that the brake pedal is pressed, or when the usage mode indicates that the vehicle is in the standby mode and the brake pedal status information indicates that the brake pedal is pressed, determine the ignition control signal for the vehicle according to the vehicle's Bluetooth key learning status information, right zone controller learning status information, key authentication status information, vehicle body anti-theft status information, over-the-air download mode information, and port status information of the signal output port.

[0058] In the present application, it is possible to monitor whether an automatic parking signal or an automatic parking instruction is received to determine whether the vehicle requests automatic parking: if an automatic parking signal or an automatic parking instruction is received, the vehicle requests automatic parking; if an automatic parking signal or an automatic parking instruction is not received, the vehicle does not request automatic parking. Whether automatic parking is requested can be indicated by parking status information, for example, parking status information 0-1 indicates that automatic parking is requested, and parking status information 0 indicates that automatic parking is not requested.

[0059] The Bluetooth key learning status information is used to indicate the learning status of the Bluetooth key of the vehicle. The Bluetooth key learning status information can be in the form of numbers, letters or text; for example, the Bluetooth key learning status information is 0, indicating that the learning of the Bluetooth key is undefined, the Bluetooth key learning status information is 1, indicating that the Bluetooth key has not been learned, and the Bluetooth key learning status information is 2, indicating that the Bluetooth key has been learned.

[0060] The right area controller learning status information is used to indicate the learning status of the right area controller (zcur) of the vehicle. The right area controller learning status information can be in the form of text, letters or numbers; for example, the right area controller learning status information is 0, indicating that the learning of the right area controller is not defined, the right area controller learning status information is 1, indicating that the right area controller has not been learned, and the right area controller learning status information is 2, indicating that the right area controller has been learned.

[0061] The vehicle body anti-theft status information is used to indicate the anti-theft status of the vehicle body. The vehicle body anti-theft status information can be in the form of numbers, letters or text. For example, the vehicle body anti-theft status information is 0, indicating that the vehicle body anti-theft status is released, and the vehicle body anti-theft status information is 1, indicating that the vehicle body anti-theft status is not released.

[0062] Specifically, when the usage mode indicates that the vehicle is in comfort mode, the vehicle has not requested automatic parking, and the brake pedal status information indicates that the brake pedal is pressed, if it is determined that the Bluetooth key learning status information indicates that the Bluetooth key is not defined or the Bluetooth key is learning, the key authentication status information indicates that the key authentication is passed, the right area controller learning status information indicates that the right area controller has not been learned, the body anti-theft status information indicates that the body anti-theft status is released, the port status information indicates the preset port status, and the air download mode information indicates that the vehicle is in non-air download mode, it is determined that the ignition control signal is an ignition signal, otherwise, the ignition control signal is not generated, that is, the vehicle is kept in the off state.

[0063] Alternatively, when the usage mode indicates that the vehicle is in the comfort mode, the vehicle does not request automatic parking, and the brake pedal status information indicates that the brake pedal is depressed, it is determined that the Bluetooth key learning status information indicates that the Bluetooth key is not defined or the Bluetooth key is learning, the right zone controller learning status information indicates that the right zone controller has been learned or is not defined, the vehicle body anti-theft status information indicates that the vehicle body anti-theft status is released, the port status information indicates the preset port status, and the air download mode information indicates that the vehicle is in the non-air download mode, and the ignition control signal is determined to be the ignition signal. Otherwise, the ignition control signal is not generated, that is, the vehicle is kept in the off state. That is, when the right zone controller learning status information indicates that the right zone controller has been learned or is not defined, the key authentication status information may not be referenced.

[0064] In addition, it may be that when the usage mode indicates that the vehicle is in standby mode and the brake pedal status information indicates that the brake pedal is pressed, if it is determined that the Bluetooth key learning status information indicates that the Bluetooth key is not learned or the Bluetooth key is learning, the key authentication status information indicates that the key authentication is passed, the right area controller learning status information indicates that the right area controller has not been learned, the body anti-theft status information indicates that the body anti-theft status is released, the port status information indicates the preset port status, and the air download mode information indicates that the vehicle is in non-air download mode, it is determined that the ignition control signal is an ignition signal, otherwise, the ignition control signal is not generated, that is, the vehicle is kept in the off state.

[0065] Similarly, it may be that when the usage mode indicates that the vehicle is in standby mode and the brake pedal status information indicates that the brake pedal is pressed, it is determined that the Bluetooth key learning status information indicates that the Bluetooth key is not learned or the Bluetooth key is learning, the right area controller learning status information indicates that the right area controller has been learned or is undefined, the body anti-theft status information indicates that the body anti-theft status is released, the port status information indicates the preset port status, and the air download mode information indicates that the vehicle is in non-air download mode, it is determined that the ignition control signal is an ignition signal, otherwise, the ignition control signal is not generated, that is, the vehicle is kept in the off state.

[0066] When the numerical values ​​in the above examples are used to indicate different status information, the determination means are shown in Table 2, which is as follows:

[0067] Table 2

[0068]

[0069]

[0070] The parking status information is used to indicate whether automatic parking is requested. 0-1 indicates requesting automatic parking. A parking status information of "-" indicates not referring to the parking status information. A key authentication status information of "-" indicates not referring to the key authentication status information.

[0071] In yet another embodiment, if the ignition status information indicates that the vehicle is in an off state, S130 may further include: if the usage mode indicates that the vehicle is in a comfort mode and the vehicle requests automatic parking, or the usage mode indicates that the vehicle is in a driving mode, determining the ignition control signal of the vehicle according to the port status information of the signal output port of the vehicle.

[0072] That is, in both cases where the usage mode indicates that the vehicle is in the comfort mode and the vehicle requests automatic parking, or the usage mode indicates that the vehicle is in the driving mode, the ignition control signal of the vehicle can be determined by referring to the port status information.

[0073] It can be that, when the usage mode indicates that the vehicle is in the comfort mode and the vehicle requests automatic parking, or when the usage mode indicates that the vehicle is in the driving mode, if it is determined that the port fault status information indicates a preset port status, the ignition control signal is determined to be an ignition signal, otherwise, the ignition control signal is not generated, that is, the vehicle is kept in the off state.

[0074] When the numerical values ​​in the above examples are used to indicate different status information, the determination means here are shown in Table 3, which is as follows:

[0075] Table 3

[0076] Usage Mode Parking status information Port status information Brake pedal status information Ignition control signal 1 0-1 0 / 2 / 3 0 to 1 1 3 - 0 / 2 / 3 0 to 1 1

[0077] Among them, in the driving mode, the brake pedal is definitely pressed. Therefore, when the usage mode indicates that the vehicle is in the driving mode, the brake pedal state information is definitely that the brake pedal is pressed.

[0078] As mentioned above, for the case where the vehicle is in the off state, three means of determining the ignition control signal are provided. Based on the above three determination means and the representation of each state information, the process of obtaining the ignition control signal is as follows: Figure 3 As shown;

[0079] In the case where the brake pedal state is 0-1, it indicates that the brake pedal is pressed. If the use mode signal is not detected, it is determined that the use mode detection result indicates that no use mode is detected. If the key authentication state is 0 / 1 / 3to 2, the OTA mode is 0, and the port state of the signal output port is 0 / 2 / 3, it is determined that the ignition control signal is an ignition signal;

[0080] If it is detected that the usage mode is 0, the Bluetooth key learning status is 0 / 1, the ZCUR (right zone controller) learning status is 1, the key authentication status is 2, the vehicle anti-theft status is 0, the OTA mode is 0, and the port status of the signal output port is 0 / 2 / 3, then the ignition control signal is determined to be an ignition signal;

[0081] If it is detected that the usage mode is 0, the Bluetooth key learning state is 0 / 1, the ZCUR learning state is 0 or 2, the vehicle anti-theft state is 0, the OTA mode is 0, and the port state of the signal output port is 0 / 2 / 3, then the ignition control signal is determined to be an ignition signal;

[0082] If it is detected that the usage mode is 1, automatic parking is not requested, the Bluetooth key learning status is 0 / 1, the ZCUR learning status is 1, the key authentication status is 2, the vehicle body anti-theft status is 0, the OTA mode is 0, and the port status of the signal output port is 0 / 2 / 3, then the ignition control signal is determined to be an ignition signal;

[0083] If it is detected that the usage mode is 1, automatic parking is not requested, the Bluetooth key learning state is 0 / 1, the ZCUR learning state is 0 or 2, the vehicle body anti-theft state is 0, the OTA mode is 0, and the port state of the signal output port is 0 / 2 / 3, then the ignition control signal is determined to be an ignition signal;

[0084] If it is detected that the use mode is 1, automatic parking is requested, and the port status is 0 / 2 / 3, then the ignition control signal is determined to be an ignition signal;

[0085] If it is detected that the usage mode is 3 and the port status is 0 / 2 / 3, it is determined that the ignition control signal is an ignition signal.

[0086] In another embodiment, when the ignition status information indicates that the vehicle is in the ignition state, S130 may include: if the port status information indicates that the signal output port of the vehicle enters the target port state from the normal state, determining the ignition off signal as the ignition control signal of the vehicle; wherein the target port state is a short circuit state or an overload state.

[0087] That is to say, when the ignition status information indicates that the vehicle is in the ignition state, the ignition control signal is determined directly based on the port status information; if the port status information indicates that the signal output port enters the electrical short circuit state from the normal state, or enters the overload state from the normal state, the flameout signal is directly determined as the ignition control signal for the vehicle.

[0088] At this time, when the numerical values ​​in the above example are used to indicate different state information, the determination means here are shown in Table 4, which is as follows:

[0089] Table 4

[0090] Port status information Ignition control signal 0to 1 / 4 0

[0091] In another embodiment, the ignition status information indicates that the vehicle is in the ignition state, and S130 may also include: if the port status information does not indicate that the signal output port of the vehicle enters the target port state from the normal state, and the use mode indicates that the vehicle satisfies the preset use mode conversion method, determining the ignition off signal as the ignition control signal of the vehicle; wherein the target port state is a short circuit state to the ground or an overload state; when at least one of the vehicle enters the standby mode from the driving mode, enters the comfort mode from the driving mode, and enters the standby mode from the comfort mode occurs, determining that the vehicle satisfies the preset use mode conversion method.

[0092] At this time, when the numerical values ​​in the above example are used to indicate different state information, the determination means here are shown in Table 5, which is as follows:

[0093] Table 5

[0094] Usage Mode Port status information Ignition control signal 3 to 0 / 1 Not satisfied with 0 to 1 / 4 0 1 to 0 Not satisfied with 0 to 1 / 4 0

[0095] In another embodiment, the ignition status information indicates that the vehicle is in the ignition state, and S130 may also include: if the port status information indicates that the signal output port of the vehicle has not entered the target port state from the normal state, and the use mode indicates that the vehicle does not satisfy the preset use mode conversion method, the ignition control signal of the vehicle is determined according to the door status information of the vehicle, the main driver's seat status information, the gear status information, the offline test mode status information, the vehicle speed information and the use mode indicated by the use mode; wherein the target port state is a short circuit state to the ground or an overload state; when at least one of the vehicle enters the standby mode from the driving mode, the comfort mode from the driving mode, and the standby mode from the comfort mode occurs, it is determined that the vehicle satisfies the preset use mode conversion method.

[0096] The door status information is used to indicate the door status of the vehicle, and may include the main driver's door status information, the front passenger's door status information, the left rear door status information and the right rear door status information. The door status information (any one of the main driver's door status information, the front passenger's door status information, the left rear door status information and the right rear door status information) may be represented by numbers, letters or text; for example, if the door status information (any one of the main driver's door status information, the front passenger's door status information, the left rear door status information and the right rear door status information) is 1, it indicates that the corresponding door is in an open state; if the door status information (any one of the main driver's door status information, the front passenger's door status information, the left rear door status information and the right rear door status information) is 0, it indicates that the corresponding door is in a closed state.

[0097] The main driver seat status information is used to indicate the status of the main driver seat. The main driver seat status information can be in the form of numbers, letters or text; for example, the main driver seat status information is 1, indicating that the main driver seat is unoccupied, the main driver seat status information is 2, indicating that the main driver seat is occupied, and the main driver seat status information is 3, indicating that the main driver seat is invalid.

[0098] The gear status information is used to indicate the gear position of the vehicle. The gear status information can be in the form of numbers, letters or text; for example, the gear status information is 1, indicating that the vehicle is in D gear (driving gear), the gear status information is 2, indicating that the vehicle is in N gear (neutral gear), the gear status information is 3, indicating that the vehicle is in R gear (reverse gear), and the gear status information is 4, indicating that the vehicle is in P gear (parking gear).

[0099] The offline test mode status information is used to indicate whether the vehicle is in the offline test mode. For example, the offline test mode status information is 0x55, indicating that the vehicle has disabled the offline test mode. The offline test mode status information is 1, indicating that the vehicle is in the offline test mode.

[0100] Specifically, when the port status information indicates that the signal output port of the vehicle has not entered the target port state from the normal state, and the usage mode indicates that the vehicle does not meet the preset usage mode change method, if it is determined according to the door status information that the main driving door is open or the driver is determined to have left the seat according to the main driver seat status information, and the gear status information continues to indicate that the vehicle is in the parking gear, the offline test mode status information indicates that the vehicle has disabled the offline test mode, the vehicle speed does not exceed the vehicle speed threshold (the vehicle speed threshold is, for example, 5km / h), and the usage mode indicated by the usage mode is the comfort mode, then it can be determined that the ignition control signal for the vehicle is the ignition off control signal, otherwise, no ignition control signal is generated, that is, the vehicle ignition state is maintained.

[0101] At this time, when the numerical values ​​in the above example are used to indicate different state information, the determination means here are shown in Table 6, which is as follows:

[0102] Table 6

[0103]

[0104] Among them, the main driver's seat status information changes from 2 to 1, indicating that the main driver's seat status information changes from occupied to unoccupied, which means that the driver has left the seat; the main driver's seat status information changes from 3 to 1, indicating that the main driver's seat status information changes from invalid to unoccupied, which also means that the driver has left the seat.

[0105] Specifically, when the port status information indicates that the signal output port of the vehicle has not entered the target port state from the normal state, and the usage mode indicates that the vehicle does not satisfy the preset usage mode change method, if it is determined according to the door status information that any door has changed from open to closed and the other doors are closed, and the main driver's seat status information is continued to indicate that the driver has not left the seat, the gear status information indicates that the vehicle is in the parking gear, the offline test mode status information indicates that the vehicle has disabled the offline test mode, the vehicle speed does not exceed the vehicle speed threshold (the vehicle speed threshold is, for example, 5km / h), and the usage mode indicated by the usage mode is the comfort mode, then the ignition control signal for the vehicle is determined to be the ignition off control signal, otherwise, no ignition control signal is generated, that is, the vehicle ignition state is maintained.

[0106] At this time, when the numerical values ​​in the above example are used to indicate different information, the determination means here are shown in Table 7, which is as follows:

[0107] Table 7

[0108]

[0109] As mentioned above, for the case where the vehicle is in the ignition state, three means of determining the ignition control signal are provided. Based on the above three determination means and the representation methods of each state information, the process of obtaining the ignition control signal is as follows: Figure 4 As shown;

[0110] When the port status of the signal output port is 0 to 1 / 4, the ignition control signal is directly determined to be an ignition off signal;

[0111] When the port status of the signal output port does not satisfy 0 to 1 / 4, but satisfies the use mode 3 to 0 / 1 or satisfies the use mode 1 to 0, the ignition control signal is directly determined to be a flameout signal;

[0112] When the port status of the signal output port does not meet 0 to 1 / 4, does not meet the use mode 3 to 0 / 1 and does not meet the use mode 1 to 0, it is determined that the main driving door state is 0 to 1 (meaning the main driving door is open), the main driving seat state is 1, the use mode is 1, the gear state is 4, the non-offline test mode and the vehicle speed is less than 5 km / h, and the ignition control signal is determined to be a flameout signal; 5 km / h is the vehicle speed threshold, and other vehicle speed thresholds can be set based on demand;

[0113] When the port state of the signal output port does not satisfy 0to 1 / 4, does not satisfy the usage mode 3to 0 / 1 and does not satisfy the usage mode 1to 0, it is determined that the main driving door is not 0to 1 (meaning that the main driving door is not open), any door state is 1to 0 (meaning that the door changes from open to closed), the remaining door states are 0 (meaning that all doors except the aforementioned doors that change from open to closed are closed), the main driver's seat state is 1, usage mode 1, gear state 4, non-offline test mode and the vehicle speed is less than 5km / h, and the ignition control signal is determined to be an ignition off signal.

[0114] S140: Control the ignition state of the vehicle according to the ignition control signal.

[0115] After obtaining the corresponding ignition control signal, the ignition state of the vehicle can be controlled according to the ignition control signal, that is: the ignition control signal is an ignition signal, which controls the ignition of the vehicle to enter the ignition state; the ignition control signal is an off-fire signal, which controls the off-fire of the vehicle to enter the off-fire state.

[0116] In this embodiment, the usage mode of the vehicle is first determined, and then the corresponding auxiliary detection information is determined based on the usage mode. Then, based on the usage mode and / or the auxiliary detection information, the ignition control signal of the vehicle is determined. It is no longer limited to controlling the vehicle ignition state only by the ignition switch, but the ignition control signal is determined according to the actual usage mode of the vehicle and / or the auxiliary detection information corresponding to the usage mode, thereby achieving the purpose of adaptively determining the ignition control signal according to the actual state of the vehicle, thereby improving the accuracy of ignition control.

[0117] In addition, in the present embodiment, reference is made to the vehicle's door status information, driver's seat status information, gear status information, offline test mode status information, vehicle speed information, vehicle's Bluetooth key learning status information, right zone controller learning status information, key authentication status information, vehicle body anti-theft status information, air download mode information, and port status information of the signal output port to jointly determine the vehicle's ignition control signal, so that the determined ignition control signal is more closely matched with the vehicle's actual status, the ignition control signal has higher accuracy, and the ignition control accuracy is further improved.
