Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of vehicle control, in particular to a P-gear button recognition method, device, equipment and storage medium. BACKGROUND

[0002] With the development of the automobile industry, the degree of electrification of automobiles is getting higher and higher, and the traditional mechanical hand brake is replaced by an electronic hand brake. At present, the electronic hand brake can be integrated on the P-gear (i.e. parking gear) button, which can simulate the hand brake pull-up by pressing the P-gear button, and simulate the hand brake release by switching the R-gear (i.e. reverse gear), N-gear (i.e. neutral gear) and D-gear (i.e. forward gear). With the increasing integration, the requirement for functional safety is also increasing. At present, the voltage state of the double circuits of the P-gear button is collected to determine that both switches are closed, and then the state of the P-gear button is determined as pressed to control the emergency braking of the vehicle.

[0003] However, in the above method, when any one of the switches in the P-gear button fails, the state of the P-gear button cannot be accurately recognized according to the braking demand of the driver, especially when the vehicle is driving at high speed. If the state of the P-gear button is incorrectly recognized, it will cause danger. For example, when the vehicle is driving at high speed, if the driver does not press the P-gear button, but the electrical system fails to recognize that the P-gear button is pressed, it will cause the vehicle to brake urgently and cause danger. Or, when the vehicle is driving at high speed, if the driver has the demand to press the P-gear button for a long time to perform dynamic parking, but the electrical system cannot correctly recognize the demand for dynamic parking, which will also cause danger. Moreover, when using a double-circuit P-gear button, if the driver presses the edge of the P-gear button, the two switches cannot be pressed at the same time, which will cause the system to incorrectly recognize the state of the P-gear button, thereby reducing the accuracy of recognizing the P-gear button. SUMMARY

[0004] The purpose of the present application is to provide a P-gear button recognition method, device, equipment and storage medium to solve the technical problem that when any one of the switches in the P-gear button fails, the state of the P-gear button cannot be accurately recognized according to the braking demand of the driver.

The present application can be implemented or applied in other different specific embodiments, and the details in the description can be modified or changed based on different views and applications without departing from the spirit of the present application. It should be understood that the preferred embodiments are only for illustrating the present application, but not for limiting the protection scope of the present application.

[0044] It should be noted that the diagrams provided in the following embodiments only schematically illustrate the basic concept of the present application, and only the components related to the present application are shown in the diagrams, but not the number, shape and size of the components in actual implementation. The shape, number and ratio of the components in actual implementation can be arbitrarily changed, and the layout pattern of the components can be more complex.

[0045] For the convenience of understanding, the P range button recognition method provided by the present application is specifically introduced below in combination with the accompanying drawings.

[0046] The P range button recognition method provided by the embodiments of the present application can be applied to a P range button recognition system. Figure 1 is a structural schematic diagram of a P range button recognition system according to an exemplary embodiment. As shown in Figure 1 , the P range button recognition system 10 comprises a fault determination module 11, an information acquisition module 12 and a P range button state recognition module 13.

[0047] The fault determination module 11 is configured to detect a voltage signal of each of a plurality of acquisition loops of the P gear button of the target vehicle, and determine whether the P gear button has a first fault based on the voltage signal of each of the plurality of acquisition loops.

[0048] Figure 2 is a flowchart of a P gear button recognition method according to an example embodiment, as shown in Figure 2 The P gear button recognition method includes the following steps:

[0049] S201, detecting a voltage signal of each of a plurality of acquisition loops of the P gear button of the target vehicle, and determining whether the P gear button has a first fault based on the voltage signal of each of the plurality of acquisition loops.

[0050] The voltage signal of the acquisition loop is any one of a low-level signal and a high-level signal, and the first fault is used to indicate that the voltage signals of each of the plurality of acquisition loops of the P gear button are inconsistent.

[0051] Optionally, within a first preset time period after the vehicle control unit is woken up, the vehicle control unit (VCU) can be used to detect the voltage signal of each of the plurality of acquisition loops of the P gear button of the target vehicle.

[0052] For example, the first preset time period can be 8s, 10s, 12s, or any reasonable value, and the P gear button of the target vehicle can include three acquisition loops. Figure 3 is a schematic diagram of a three-way P gear button position acquisition circuit of a vehicle control unit according to an example embodiment, as shown in Figure 3As shown, the power supply voltages (volt current condenser, VCC) 1, VCC2, VCC3 of the circuit are three independent voltage sources, R3, R6, R9 are pull-up resistors, P10, P11, P12 are three P-gear key acquisition circuit digital acquisition interfaces connected with the vehicle controller. S1, S2, S3 are switches in the three P-gear key acquisition circuits, when the P-gear key is pressed down, S1, S2, S3 are in the closed state, when the P-gear key is released, S1, S2, S3 are in the open state.

[0053] R1, R2, R4, R5, R7, R8 are resistors in the three P-gear key acquisition circuits, taking the acquisition circuit corresponding to P10 as an example, when the P-gear key is pressed down, the voltage acquired by P10 on the vehicle controller is VCC1*R1 / (R1+R3), at this time, the key state signal of the acquisition circuit is low (i.e. the voltage signal of the acquisition circuit is a low level signal); when the P-gear key is not pressed down, the voltage acquired by P10 on the vehicle controller is VCC1*(R1+R2) / (R1+R2+R3), at this time, the key state signal of the acquisition circuit is high (i.e. the voltage signal of the acquisition circuit is a high level signal).

[0054] Figure 4 is a distribution diagram of three P-gear key switch positions according to an exemplary embodiment, as shown in Figure 4 As shown, the three acquisition positions of the three P-gear keys are in equilateral triangle distribution, so as to ensure accurate acquisition of the corresponding key state when the P-gear key is pressed down by the driver.

[0055] Optionally, based on the voltage signals of each acquisition circuit, it can be determined whether the voltage signal of at least one acquisition circuit in the plurality of acquisition circuits is consistent with the acquisition circuits other than the at least one acquisition circuit in the plurality of acquisition circuits, if the voltage signal of the at least one acquisition circuit in the plurality of acquisition circuits is consistent with the acquisition circuits other than the at least one acquisition circuit in the plurality of acquisition circuits, it is determined that the P-gear key does not have the first fault; if the voltage signal of the at least one acquisition circuit in the plurality of acquisition circuits is inconsistent with the acquisition circuits other than the at least one acquisition circuit in the plurality of acquisition circuits, and the duration of the inconsistency between the voltage signal of the at least one acquisition circuit in the plurality of acquisition circuits and the acquisition circuits other than the at least one acquisition circuit in the plurality of acquisition circuits is greater than a second preset duration, it is determined that the P-gear key has the first fault, and the fault code corresponding to the first fault, the voltage signal of each acquisition circuit and the pull-up power source corresponding to each acquisition circuit are recorded. Based on the fault code corresponding to the first fault, the fault maintenance information is sent to and displayed on the instrument panel of the target vehicle.

[0056] Exemplarily, the second preset time length can be 6s, 8s, 10s, or any reasonable numerical value. If the voltage signal of one of the three acquisition circuits included in the three-path P-gear button is inconsistent with the voltage signals of the other two acquisition circuits, and the duration of the inconsistency is greater than 8s, it is determined that the three-path P-gear button has the first fault. The fault maintenance information can be "P-gear button fault, please contact the maintenance station in time".

[0057] It should be noted that the voltage signal of each acquisition circuit and the pull-up power supply corresponding to each acquisition circuit are used to analyze and locate the cause of the first fault.

[0058] S202, acquire state information and environment information of the target vehicle.

[0059] The state information includes at least one of the following: brake signal, driving speed, acceleration, the brake signal is used to indicate whether the target vehicle is braking, and the environment information is used to indicate whether there is an obstacle in the target area corresponding to the current position of the target vehicle.

[0060] Optionally, the state information of the target vehicle can be collected by the chassis controller of the target vehicle, the environment information can be acquired by the intelligent driving controller, and the state information collected by the chassis controller and the environment information acquired by the intelligent driving controller can be acquired by the vehicle controller of the target vehicle.

[0061] Exemplarily, the obstacle can be a vehicle or a pedestrian.

[0062] S203, based on the state information, the environment information, and the voltage signal of each acquisition circuit in the plurality of acquisition circuits, determine whether the P-gear button is pressed in the case that the P-gear button has the first fault.

[0063] Optionally, in the case that the P-gear button fault state obtained by the power-on diagnosis of the vehicle controller is that the P-gear button has the first fault, the P-gear button can be determined to be pressed based on the state information, the environment information, and the voltage signal of each acquisition circuit in the plurality of acquisition circuits.

[0064] S204, based on the state information, the environment information, and the voltage signal of each acquisition circuit in the plurality of acquisition circuits, determine whether the P-gear button is pressed in the case that the P-gear button does not have the first fault.

[0065] Optionally, in the case that the P-gear button fault state obtained by the power-on diagnosis of the vehicle controller is that the P-gear button does not have the first fault, the P-gear button can be determined to be pressed based on the state information, the environment information, and the voltage signal of each acquisition circuit in the plurality of acquisition circuits.

[0066] Figure 5 is a flowchart of yet another P-range button recognition method according to an exemplary embodiment, as Figure 5 shown, the method further includes the following steps:

[0067] S301, based on the voltage signals of each of the plurality of acquisition loops included in the P-range button of the target vehicle, determine whether the P-range button has a second fault.

[0068] wherein the second fault is indicative of the voltage signals of each of the plurality of acquisition loops included in the P-range button being low-level signals.

[0069] Optionally, within a first preset time duration after the vehicle controller is woken up, the voltage signals of each of the plurality of acquisition loops included in the P-range button of the target vehicle can be detected by the vehicle controller, and it is determined whether the voltage signals of each of the plurality of acquisition loops included in the P-range button of the target vehicle are all low-level signals. If the voltage signals of each of the plurality of acquisition loops included in the P-range button of the target vehicle are all low-level signals, it is determined that the P-range button has a second fault; if there is any one of the plurality of acquisition loops included in the P-range button of the target vehicle whose voltage signal is a high-level signal, it is determined that the P-range button does not have a second fault.

[0070] For example, if the voltage signals of each of the three acquisition loops included in the three-way P-range button are all low-level signals (i.e., all the three acquisition loops are in a pressed state), it is determined that the P-range button has a second fault; if there is any one of the three acquisition loops included in the three-way P-range button whose voltage signal is a high-level signal (i.e., one of the three acquisition loops is in an unpressed state), it is determined that the P-range button does not have a second fault.

[0071] S302, in the case where the P-range button has a second fault, determine that the P-range button cannot be reset, disable the P-range button, and display a maintenance prompt information.

[0072] Optionally, in the case where the P-range button has a second fault, it can be determined that the P-range button cannot be reset, and the P-range button is disabled in the current power-on period. The fault code corresponding to the second fault, the voltage signals of each acquisition loop, and the pull-up power source corresponding to each acquisition loop are recorded. Based on the fault code corresponding to the second fault, a maintenance prompt information is sent to and displayed on the instrument panel of the target vehicle.

[0073] For example, the maintenance prompt information can be "The P-range button cannot be reset and used. Please use the off-vehicle P-in function and contact the maintenance station in time before leaving the vehicle".

If the P-gear button is determined to be pressed, the vehicle controller can control the target vehicle to apply emergency braking.

If the P gear button does not have a first fault, the driving speed is greater than the second preset threshold, and the voltage signals of at least N acquisition circuits in the multiple acquisition circuits are all low level signals, then the P gear button is determined to be pressed.

[0103] Where N is a positive integer.

[0104] Optionally, if the P-gear button does not exhibit a first or second fault, the driving speed exceeds a second preset threshold, and the voltage signals of at least N of the multiple acquisition circuits are all low-level signals, then it can be determined that the P-gear button has been pressed. If the P-gear button is determined to be pressed, the vehicle controller can initiate emergency braking of the target vehicle.

[0105] For example, N acquisition circuits can be two or three acquisition circuits. If the P gear button does not have a first fault or a second fault, the driving speed is greater than the second preset threshold, and two of the three acquisition circuits included in the three P gear buttons are low-level signals, it can be determined that the P gear button is pressed.
