[0002] The accelerator pedal refers to the accelerator pedal on the vehicle, also known as the throttle. When the driver steps on the accelerator pedal, the accelerator pedal can output two independent detection signals for the vehicle controller to analyze the opening degree of the accelerator pedal to ensure functional safety. When the accelerator pedal fails, both detection signals are invalid, the vehicle controller cannot obtain the detection signals, and thus cannot analyze the opening degree of the accelerator pedal. At this time, the driver cannot control the vehicle acceleration through the accelerator pedal, and the vehicle enters a fault limping state, and the vehicle travels at a low fixed speed. Since the vehicle travels at a slow speed and cannot accelerate, and the vehicle cannot go to the maintenance center, it can only rely on a tow truck for rescue, especially when traveling slowly on an expressway or highway, which has a high safety risk.

[0003] Therefore, how to improve the safety of the driver and passengers when the accelerator pedal fails is a technical problem that needs to be solved by those skilled in the art. SUMMARY

[0037] In order for those skilled in the art to better understand the technical solutions of the present application, the present application will be further described in detail below in combination with the drawings and specific embodiments.

[0038] The embodiment of the present application provides a vehicle control method, a vehicle control device, a vehicle controller and a vehicle, wherein the vehicle comprises the above-mentioned vehicle controller 11, and further comprises an accelerator pedal 12, a shifter 13, a body controller 14, a brake controller 15 and a central control display screen 16 and the like components, wherein, as shown in the figure, Figure 1 The vehicle controller 11 is respectively connected in signal with the accelerator pedal 12, the shifter 13, the body controller 14, the brake controller 15, the central control display screen 16 and the like components, and specifically how to realize the signal connection is the prior art well known to those skilled in the art, and in order to save space, it will not be described here.

[0039] The vehicle controller 11 is a power controller of the vehicle, which has the functions of current gear calculation, accelerator pedal 12 opening degree calculation, brake pedal depression calculation, CAN communication analysis and diagnosis.

[0040] The accelerator pedal 12 mainly controls the output power of the vehicle, and the accelerator pedal 12 transmits the user's stepping action through two independent detection signals, and the vehicle controller 11 can analyze the depression amplitude of the accelerator pedal 12 through the two independent detection signals, and can also diagnose whether the accelerator pedal 12 has a fault.

[0041] The vehicle control method provided by the embodiment of the present application can realize the power control of the target vehicle where the accelerator pedal 12 (i.e. the throttle) is faulty, and ensure the safety of the driver and passengers.

[0042] Specifically, as shown in Figure 2 The vehicle control method comprises the following steps:

[0043] S100: enabling a power control function when the accelerator pedal 12 fails;

[0044] When the accelerator pedal 12 does not fail, the vehicle controller 11 can control the output power by the depression amplitude of the accelerator pedal 12 to meet the power demand of the target vehicle.

[0045] When the accelerator pedal 12 fails, the vehicle controller 11 cannot control the output power by analyzing the depression amplitude of the accelerator pedal 12, at this time, the target vehicle enables the power control function.

[0046] The vehicle controller 11 diagnoses whether the accelerator pedal 12 fails, and the specific diagnosis is usually to detect signal short circuit, open circuit, ground short circuit, signal out-of-range, and two signals out of proportion, etc. When both signals are abnormal, the accelerator pedal 12 is in a fault state. Specifically, the diagnosis principle of the accelerator pedal 12 failure is the prior art known to those skilled in the art, and to save space, it will not be repeated here.

[0047] S200: When it is detected that the specified component of the target vehicle to which the accelerator pedal 12 belongs is subjected to a specified operation, performing a power control operation corresponding to the power control function according to the specified operation.

[0048] After the target vehicle enables the power control function, the user can perform a specified operation on the specified component of the target vehicle, and the vehicle controller 11 can obtain the specified operation through the corresponding sensor, and then the vehicle controller 11 can perform a power control operation corresponding to the power control function according to the specified operation to control the output power of the target vehicle and meet the power demand of the target vehicle.

[0049] That is, the vehicle control method provided by the embodiment can execute a power control operation corresponding to the power control function according to the specified operation of the specified component of the target vehicle to which the accelerator pedal 12 belongs when the power control cannot be realized by using the accelerator pedal 12, so that the control of the output power of the target vehicle can be realized when the accelerator pedal 12 fails, the power demand of the target vehicle can be met, the target vehicle can be driven to a safe position or a service center, the rescue cost can be reduced, the vehicle abandonment rate can be reduced, the compatibility and ease of use of the power control can be improved, the safety of the user can be improved, the needs of the user can be met, and the user experience can be improved.

[0050] In the embodiment, the specified component refers to a hardware in the vehicle, and the user can control the power by specifying the hardware. Compared with the power control realized by only the screen (i.e., the central display screen 16), the user can have a better experience and the reliability is better.

[0051] In the embodiment, the specified component of the target vehicle refers to the gear lever of the gear shifter 13 of the target vehicle. The specified operation on the specified component of the target vehicle to which the accelerator pedal 12 belongs includes the specified operation on the gear lever of the gear shifter of the target vehicle to which the accelerator pedal belongs, such as Figure 3 As shown in the above step S200, the power control operation corresponding to the power control function is executed according to the specified operation when the specified operation on the gear lever of the gear shifter of the target vehicle to which the accelerator pedal belongs is detected.

[0052] The user operates the gear lever, and the gear shifter 13 can recognize the gear shifting operation of the user according to the operation of the user on the gear lever, and output the gear related signal through the CAN signal. The corresponding gear shifting (shifting the driving direction) is executed by the vehicle controller 11. In the conventional state, the user operates the gear lever to make the vehicle engage in the required gear, such as P (parking gear), R (reverse gear), N (neutral gear), D (forward gear), etc.

[0053] The gear shifter 13 can output the specific position of the gear lever, and the gear shifter 13 is a reset type gear shifter 13. The user can operate the gear lever to be moved to the target position. When the user removes the force on the gear lever, the gear lever returns to the original position Z, and each gear is distributed on the front and back of the original position Z.

[0054] As shown in the above step S200, the power control operation corresponding to the power control function is executed according to the specified operation when the specified operation on the gear lever of the gear shifter of the target vehicle to which the accelerator pedal belongs is detected. Figure 5 As shown in the above step S200, the power control operation corresponding to the power control function is executed according to the specified operation when the specified operation on the gear lever of the gear shifter of the target vehicle to which the accelerator pedal belongs is detected.

[0055] When the power control mode is enabled, the user can change the position of the gear lever of the gear shifter 13 by the specified operation on the gear lever of the gear shifter 13. The vehicle controller 11 can obtain the position change of the gear lever through the gear shifter 13, and adjust the output power through the position change of the gear lever after the power control function is enabled. At this time, the gear shifter 13 temporarily plays a role in power adjustment, and the operation is more convenient.

[0056] Of course, in the embodiment, the specified component is not limited to the gear lever, and can also be a winker lever. When the power control function is enabled, the vehicle controller 11 can execute the power control operation corresponding to the power control function according to the position change of the winker lever when the user operates the winker lever to cause the winker lever to change position. When the power control operation corresponding to the power control function is executed by the position change of the gear lever of the gear lever 13, the user can operate conveniently, and the application of other functions of the vehicle is not affected.

[0057] Specifically, the step S200 includes:

[0058] When the gear lever of the gear lever 13 is moved from the original position to the first position, the output power is increased, when the gear lever of the gear lever 13 is moved from the original position to the second position, the output power is decreased, and when the gear lever of the gear lever 13 is not moved from the original position to the first position or the second position, the output power is kept unchanged. The original position is between the first position and the second position.

[0059] Preferably, the first position is D, and the second position is R, that is, when the user operates the gear lever from the original position Z to Y2, the output power is increased, and when the user operates the gear lever from the original position Z to X2, the output power is decreased. In this way, the user can understand and operate conveniently. The target vehicle must be in the driving gear position (D / R) to control the output power according to the position change of the gear lever.

[0060] The original position is between the first position and the second position, which can facilitate user operation, so that the user can perform specified operation according to demand without observation, ensuring accurate operation and improving safety.

[0061] Of course, in the embodiment, the gear lever can be moved from the original position to the first direction to increase the output power, and the gear lever can be moved from the original position to the second direction to decrease the output power. The first direction and the second direction are opposite, and the output power is adjusted only when the gear lever is moved from the original position to the first position or the second position. In this way, the output power can be controlled without being affected by the user's accidental touch on the gear lever, and the user experience is improved.

[0062] Preferably, the output power is gradually changed according to the position change of the gear lever of the gear lever 13 of the target vehicle. Specifically, when the gear lever of the gear lever 13 is moved from the original position to the first position, the output power is gradually increased according to the length of time that the gear lever stays in the first position, and the maximum output power does not exceed a preset power value. When the gear lever of the gear lever 13 is moved from the original position to the second position, the output power is gradually decreased according to the length of time that the gear lever stays in the second position.

[0063] That is, the control of the output power is gradually increased and gradually reduced, ensuring the stability of the target vehicle power change. Specifically, it can be adjusted at a certain preset speed, or it can be adjusted according to a certain gradient, which is not limited here.

[0064] Specifically, in step S200, as shown in the figure, first determine whether the shift lever is moved from the original position to the first position, and then determine whether the shift lever is moved from the original position to the second position, or first determine whether the shift lever is moved from the original position to the second position, and then determine whether the shift lever is moved from the original position to the first position. It can be. Figure 4

[0065] Further, as shown in the figure, between step S100 and step S200, the following steps are also included: Figure 3

[0066] S110: Determine whether the state of the target vehicle is the first state, the state of the target vehicle is the first state, including the state of the driving door of the target vehicle is closed and the state of the main driver seat is occupied.

[0067] S120: If the state of the target vehicle is not the first state, control the output power to be the minimum power.

[0068] In step S200, if the state of the target vehicle is the first state, when it is detected that the shift lever of the accelerator pedal belongs to the target vehicle is subjected to a specified operation, the power control operation corresponding to the power control function is executed according to the specified operation.

[0069] Wherein, the minimum power is the output power when the opening degree of the accelerator pedal 12 is zero under the condition that the accelerator pedal 12 does not malfunction.

[0070] That is, after the target vehicle enables the power control function, before the power control operation corresponding to the power control function is executed according to the specified operation, it is necessary to determine whether the state of the target vehicle is the first state, that is, the state of the target vehicle meets the state of the driving door is closed and the state of the main driver seat is occupied at the same time, which can be specifically collected by the body controller 14 The state of the driving door and the state of the main driver seat, when the state of the main driver seat is occupied, it means that the main driver seat has passengers.

[0071] If the state of the target vehicle is the first state, the output power can be adjusted through step S200, and if the state of the target vehicle is not the first state, the output power is controlled to be the minimum power, which can ensure safety.

[0072] ​​The first state can further include that the state of the safety belt of the driver seat is buckled, i.e., the target vehicle simultaneously satisfies that the state of the driver door is closed, the state of the driver seat is occupied, and the state of the safety belt of the driver seat is buckled, so as to further ensure safety. Specifically, the state of the safety belt of the driver seat can be acquired by the vehicle body controller 14.

[0073] Further, as shown in FIG. 1, after step S110 and before step S200, the method further includes the following steps. Figure 3

[0074] S130: determining whether the brake pedal of the target vehicle is in a depressed state.

[0075] S140: if the brake pedal of the target vehicle is in the depressed state, controlling the output power to be the minimum power.

[0076] In step S200, if the state of the target vehicle is the first state and the brake pedal of the target vehicle is not in the depressed state, when it is detected that the shift lever of the target vehicle to which the accelerator pedal belongs is subjected to a specified operation, a power control operation corresponding to the power control function is performed according to the specified operation.

[0077] That is to say, after the power control function is enabled, whenever any one of the following situations occurs, the output power is immediately controlled to decrease to the minimum power: it is detected that the state of the driver door is open, the state of the driver seat is empty, the state of the safety belt of the driver seat is open, and the brake pedal is depressed. In this way, safety can be further ensured.

[0078] Specifically, the vehicle controller 11 can identify whether the brake pedal is depressed through the brake controller 15, and the brake controller 15 refers to the brake control computer of the vehicle, can identify the action of the user depressing the brake pedal, measure the depression stroke of the brake pedal or the target brake force, and transmit the signal through the CAN signal. Such control has a higher functional safety level, and the signal quality is more reliable.

[0079] As shown in FIG. 1, the step S100 can be implemented through the following steps. Figure 3

[0080] S101: when the accelerator pedal 12 fails, sending a failure prompt information to the user;

[0081] S102: determining whether the indication information of enabling the power control function sent by the user according to the failure prompt information is received:

[0082] S103: if the indication information is received, enabling the power control function.

[0083] ​​When the accelerator pedal 12 fails, the user is sent a failure prompt information, informing the user that the accelerator pedal 12 fails, and the user can also interact with the vehicle controller 11 through the failure prompt information. Specifically, the user can send an indication information to the vehicle controller 11 to enable the power control function according to the failure prompt information. If the vehicle controller 11 receives the indication information, the power control function is enabled.

[0084] In step S100, after step S102, step S104 is further included: if the indication information is not received, the target vehicle is controlled to enter the limp mode.

[0085] That is, after the accelerator pedal 12 fails, the vehicle controller 11 sends a failure prompt information to the user, and the user has certain interaction. The user can send an indication information to the vehicle controller 11 to enable the power control function according to the failure prompt information. If the vehicle controller 11 receives the indication information, it means that the user agrees to enable the power control function. When the gear lever of the gear shifter of the target vehicle to which the accelerator pedal belongs is detected to be subjected to a specified operation, the power control operation corresponding to the power control function is performed according to the specified operation. If the vehicle controller 11 does not receive the indication information, it means that the user does not agree to enable the power control function, and the target vehicle is controlled to enter the limp mode. In this way, whether to enable the power control function can be determined according to the user's demand.

[0086] Of course, in the embodiment, the vehicle controller 11 can directly control the vehicle to enable the power control function after the accelerator pedal 12 fails, without needing to enable the power control function according to the indication information of the user. After the user agrees to enable the power control function through the interaction, the output power is controlled through the power control function, which can further improve the user experience.

[0087] Specifically, in the embodiment, how to send the failure prompt information to the user is not limited, as long as the failure prompt information that the accelerator pedal 12 fails can be sent to the user, and the user can interact with the vehicle control system through the failure prompt information.

[0088] The central control display screen 16 of the vehicle can receive the CAN signal and parse the information to display on the screen. Some central control display screens 16 have touch function, and some central control display screens 16 do not have touch function. The vehicle controller 11 can send the failure prompt information to the user through the central control display screen 16, and when the central control display screen 16 has touch function, the vehicle controller 11 can also interact with the user through the central control display screen 16.

[0089] Specifically, when the central control display screen 16 has a touch function, the vehicle controller 11 can send fault prompt information to the user through the central control display screen 16, such as displaying the text "Accelerator pedal malfunction, power control can be performed through the power control function, please confirm whether you agree to enable the power control function" on the screen. The user can send the instruction information by clicking "agree".

[0090] When the central control display screen 16 does not have a touch function, the vehicle controller 11 can send fault prompt information to the user through the central control display screen 16, such as the text "Accelerator pedal malfunction, power control can be performed through the power control function. Please confirm whether you agree to enable the power control function. If you agree to enable the power control function, please press the 'Designated button'". The user can send instruction information by pressing the 'Designated button'.

[0091] The vehicle controller 11 can also send voice prompts to the user through the speaker, such as "Accelerator pedal malfunction, power control can be performed through the power control function. Please confirm whether you agree to enable the power control function. If you agree to enable the power control function, please press the 'Designated button'." The user can send instruction information by pressing the 'Designated button'.

[0092] The vehicle controller 11 can also send prompts to the user through specific indicator lights, and the user can send prompts by pressing the "designated button".

[0093] The term "specified button" can be explicitly stated as any button, without any specific restrictions.

[0094] Of course, the vehicle controller 11 can also send fault prompts to the user and interact with the user according to at least two combinations of the above four methods, such as sending fault prompts to the user simultaneously through the central control display screen 16 and the speaker.

[0095] When the accelerator pedal 12 malfunctions, the power control function can be activated directly without relying on user commands after sending a fault message to the user via at least one of the central control display screen 16, speakers, or indicator lights.

[0096] Furthermore, after the power control function is enabled, a prompt message indicating that the power control function has been enabled can be sent to the user through at least one of the central control display screen 16, speakers, and indicator lights, such as "Power control function has been enabled". In addition, the central control display screen 16 can also prompt the user on how to control the output power through the specified operation of the specified component.

[0097] like Figure 3 As shown, after step S200 above, the following steps are also included:

[0098] S300: when the failure of the accelerator pedal 12 is removed, and the opening degree of the accelerator pedal 12 is not greater than the preset value, the power control function is closed;

[0099] The vehicle controller 11 diagnoses the failure of the accelerator pedal 12 in real time, controls the output power by enabling the power control function after the failure of the accelerator pedal 12, and closes the power control function when the failure of the accelerator pedal 12 is removed and the opening degree of the accelerator pedal 12 is not greater than the preset value, thereby ensuring safety.

[0100] Specifically, in the embodiment, the specific value of the preset value is not limited, and the preset value is preferably set to 0, that is, when the failure of the accelerator pedal 12 is removed and the opening degree of the accelerator pedal 12 is 0, the power control function is closed, and the output power is controlled by the opening degree of the accelerator pedal 12. At this time, the specified components of the target vehicle play their original roles, such as the user's gear lever operation of the gear selector 13 to realize gear shifting.

[0101] In addition, in the process of enabling the power control function, the highest speed and the power size need to be limited when adjusting the output power, in order to improve safety.

[0102] S400: controlling the output power according to the opening degree of the accelerator pedal 12.

[0103] The accelerator pedal 12 works normally, and the output power is controlled by the opening degree of the accelerator pedal 12.

[0104] The embodiment of the application also provides a vehicle control device, as shown in the figure, the vehicle control device comprises: Figure 6

[0105] The enabling module 21 is used for enabling the power control function when the accelerator pedal 12 fails;

[0106] The execution module 22 is used for executing the power control operation corresponding to the power control function according to the specified operation when it is detected that the specified components of the target vehicle to which the accelerator pedal 12 belongs are subjected to the specified operation.
