[0026] Figure 1 1 shows a flow chart of a first embodiment of a parking method provided by the present application. Figure 1 As shown, the method comprises the following steps:

[0027] Step S110: Responding to the parking switch failure signal, obtaining the current vehicle speed;

[0028] Among them, the parking switch failure signal means that after the user sends a parking signal, the parking hardware control switch in the parking system fails to respond, so the current vehicle speed is obtained to determine whether parking can be entered at the current speed. When the current vehicle speed is high, it means that the user is driving the vehicle at high speed and there is no need to enter the parking mode.

[0029] Step S120: If the current vehicle speed is less than a preset vehicle speed threshold, detecting a state parameter of a master cylinder pressure sensor;

[0030] Among them, if the current vehicle speed is less than the preset vehicle speed threshold, it means that the current vehicle is in an ultra-low speed driving state or the speed is 0, and the user is entering the parking state. For example, the preset vehicle speed threshold can be set to 3km / h. When the parking switch fails, the user may park the vehicle by stepping on the brake pedal. When stepping on the brake pedal, the master cylinder pressure sensor will detect the brake master cylinder pressure value, but the master cylinder pressure sensor may also fail. If the master cylinder pressure sensor fails, it will not be able to recognize that the user has issued a parking request through the brake pedal, and thus the vehicle will not be controlled to enter the parking state. Exemplarily, the wheel speed pulse signal collected by the wheel speed sensor can be sent to the brake controller module through the impact, and then the brake controller module calculates the current vehicle speed. The wheel speed sensors are distributed on the four wheels, and there are Hall type and magnetic induction type. The brake control module can be ABS (Anti-lock Braking System, anti-lock braking system), ESC (Electronic Stability Controller, electronic stability control system of the vehicle body), IBCU (wire control brake unit).

[0031] Step S130: If the state parameter of the master cylinder pressure sensor indicates an abnormal state, detecting the travel of the brake pedal;

[0032] If the state parameter of the master cylinder pressure sensor is not received, it is determined that the state parameter of the master cylinder pressure sensor is abnormal, indicating that the master cylinder pressure sensor has failed, and the travel of the brake pedal is detected to determine whether the user has a parking request.

[0033] Step S130: If the travel of the brake pedal is greater than a preset travel threshold, the caliper is controlled to be in a clamped state to enter a parking state.

[0034] If the travel of the brake pedal is greater than a preset travel threshold, it can be determined that the user has stepped on the brake pedal and there is a parking request, and the caliper is controlled to be in a clamped state, so that the current vehicle enters a parking state.

[0035] In this embodiment, by responding to the parking switch failure signal, the current vehicle speed is obtained to determine whether the vehicle can enter the parking state. If the current vehicle speed is less than the preset vehicle speed threshold, it can be determined that the vehicle has entered the parking state. The state parameters of the master cylinder pressure sensor are then detected to determine whether the master cylinder pressure sensor is in a normal state. If the master cylinder pressure sensor is in an abnormal state, it means that the master cylinder pressure sensor has failed and it is impossible to determine whether the vehicle has entered the parking state. The travel of the brake pedal is then detected. If the travel of the brake pedal is greater than the preset travel threshold, it can be determined that there is a parking request. The caliper is controlled to be in a clamped state to enter the parking state.

[0036] In another embodiment of the present application, if the travel of the brake pedal is greater than a preset travel threshold, the caliper is controlled to be in a clamped state to enter a parking state, further comprising:

[0037] If the travel of the brake pedal is greater than a preset travel threshold, the caliper is controlled to be in a clamped state after a preset delay period to enter a parking state.

[0038] In this embodiment, when the stroke of the brake pedal is greater than a preset stroke threshold, the caliper can be controlled to be in a clamped state after a preset delay period. After the preset delay period, the default parking switch will no longer respond to the parking signal sent by the user through the central control large screen soft switch, hard wire switch or electronic P gear; when the caliper is controlled to be in a clamped state after the preset delay period to avoid a delayed response to the parking switch failure signal, it conflicts with the control of the caliper to be in a clamped state when it is determined that the stroke of the brake pedal is greater than the preset stroke threshold.

[0039] Figure 2 FIG. 1 is a flow chart showing a second embodiment of a parking method provided by the present application. Figure 2 As shown, if the state parameter of the master cylinder pressure sensor is characterized as an abnormal state, detecting the travel of the brake pedal further includes the following steps:

[0040] Step S131: if the state parameter of the master cylinder pressure sensor indicates an abnormal state, detecting the travel and braking speed of the brake pedal;

[0041] Among them, if the state parameters of the master cylinder pressure sensor are characterized as an abnormal state, it means that the master cylinder pressure sensor has failed and it is impossible to determine whether the user has stepped on the brake pedal to brake. In this case, the brake pedal stroke and braking speed are detected to determine whether the caliper is controlled to clamp to enter the parking state.

[0042] If the travel of the brake pedal is greater than a preset travel threshold, the caliper is controlled to be in a clamped state to enter a parking state, further comprising the following steps:

[0043] Step S141: If the travel of the brake pedal is greater than a preset travel threshold, and the braking speed is greater than a preset braking speed threshold, the caliper is immediately controlled to be in a clamped state to enter a parking state.

[0044] Among them, if the stroke of the brake pedal is greater than the preset stroke threshold, it can be judged that the user has stepped on the brake pedal and has the intention to enter the parking state. By detecting the braking speed of the brake pedal, it is determined whether the user is eager to enter the parking state. If the braking speed of the brake pedal is greater than the preset braking speed, it can be determined that the user is eager to enter the parking state. After determining that the stroke of the brake pedal is greater than the preset stroke threshold and the braking speed is greater than the preset braking speed threshold, the caliper is immediately controlled to be clamped to enter the parking state, thereby reducing the user's waiting time and bringing a better experience to the user.

[0045] Step S142: If the travel of the brake pedal is greater than a preset travel threshold, and the braking speed is less than or equal to a preset braking speed threshold, the caliper is controlled to be in a clamped state after a preset delay period to enter a parking state.

[0046] Among them, if the braking speed is less than or equal to the preset braking speed threshold, it can be determined that the user is not in a hurry to enter the parking state. After determining that the brake pedal is greater than the preset travel threshold and the braking speed is less than the preset braking speed threshold, the caliper is controlled to be in a clamping state after a preset delay period to enter the parking state.

[0047] Figure 3 FIG. 1 is a flow chart showing a third embodiment of a parking method provided by the present application. Figure 3 As shown, if the current vehicle speed is less than the preset vehicle speed threshold, after detecting the state parameter of the master cylinder pressure sensor, the method further includes:

[0048] Step S210: If the state parameter of the master cylinder pressure sensor indicates a normal state, then detecting the travel of the brake pedal;

[0049] Step S220: If the master cylinder pressure value is less than the preset pressure value, and the brake pedal stroke is greater than the preset stroke threshold, the caliper is controlled to be in a clamping state to enter a parking state; wherein the state parameters of the master cylinder pressure sensor include the master cylinder pressure value.

[0050] In this embodiment, if the parameters of the master cylinder pressure sensor can be received, it indicates that the master cylinder pressure sensor is in a normal state, but there is still a situation where the state parameters issued by the master cylinder pressure sensor do not match the actual parameters. The larger the pressure value detected by the master cylinder pressure sensor, the longer the stroke of the brake pedal can be determined. By detecting the stroke of the stroke pedal, it is determined whether the master cylinder pressure value detected by the master cylinder pressure sensor is accurate. If the master cylinder pressure value is less than the preset pressure value and the stroke of the brake pedal is greater than the preset stroke threshold, it means that the pressure value detected by the master cylinder pressure sensor does not match the stroke of the brake pedal, and the master cylinder pressure sensor is still determined to be in a failed state and cannot enter the braking state. However, the user has a parking demand at this time. Therefore, when it is detected that the master cylinder pressure value is less than the preset pressure value and the stroke of the brake pedal is greater than the preset stroke threshold, the caliper is controlled to be clamped to ensure that the vehicle enters the parking state.

[0051] In another embodiment of the present application, the method of responding to a parking switch failure signal and obtaining the current vehicle speed further includes: detecting a current state of the parking switch; wherein the parking switch is used to control the clamping of the caliper; if the current state of the parking switch indicates that it is in an open state within a preset closed period, a parking switch failure signal is generated.

[0052] In this embodiment, the current state of the parking switch is detected to determine whether the parking switch is invalid, thereby determining whether a parking switch failure signal is generated. The parking switch is a hardware switch in the parking system, which is used to respond to the parking signal sent by the hard-wire switch in the cockpit, the P gear parking switch or the central control large screen soft switch. When the parking switch cannot respond to the parking signal, a parking switch failure signal is generated. Specifically, the current state of the parking switch can be detected to determine whether the parking switch responds to the parking signal. If the parking switch does not close after receiving the parking signal, or the parking switch pops open due to a fault after receiving the parking signal, the parking switch will be detected to be in the open state within the preset closing period, that is, a parking switch failure signal is generated.

[0053] In another embodiment of the present application, if the current vehicle speed is less than a preset vehicle speed threshold, then after detecting the state parameters of the master cylinder pressure sensor, it further includes: if the state parameters of the master cylinder pressure sensor represent a normal state, and the master cylinder pressure value is greater than or equal to the preset pressure value, then the caliper is controlled to be in a clamping state to enter a parking state; wherein, the state parameters of the master cylinder pressure sensor include the master cylinder pressure value.

[0054] In this embodiment, if the master cylinder pressure value is greater than or equal to the preset pressure value, it means that the master cylinder pressure sensor is in a normal state and can recognize the user's stepping on the brake pedal and requesting to enter the parking state. Therefore, when it is recognized that the master cylinder pressure value is greater than or equal to the preset pressure value, the caliper is directly controlled to be in a clamping state to put the vehicle into a parking state.
