Similarly, the phrase "if determined" or "if detected [the described condition or event]" can be interpreted as meaning "upon determining" or "in response to determining" or "upon detecting [the described condition or event]" or "in response to detecting [the described condition or event]" depending on the context.

[0030] In particular implementations, the terminals described in the embodiments of the present application include, but are not limited to, other portable devices such as mobile phones, laptop computers or tablet computers having a touch-sensitive surface (for example, a touchscreen display and / or a touchpad). It should also be understood that, in some embodiments, the device is not a portable communication device, but a desktop computer having a touch-sensitive surface (for example, a touchscreen display and / or a touchpad).

[0031] The parking control method, device, electronic device and vehicle provided by the embodiments of the present application can include a vehicular communication unit (VCU). The parking control method provided by the embodiments of the present application can acquire brake pedal depth information of a vehicle when it is detected that brake pedal assist of the vehicle is invalid, where the brake pedal assist is invalid refers to brake deceleration being less than a preset threshold. The VCU of the vehicle is used to determine a first deceleration corresponding to the brake pedal depth information according to a preset mapping relationship between depth and deceleration. The vehicle is decelerated and braked according to the determined first deceleration corresponding to the brake pedal depth information, so as to avoid a situation where the vehicle parking function is completely invalid due to a failure of a regional controller when it is detected that the brake pedal assist of the vehicle is invalid. This helps to improve the effectiveness of vehicle parking and the safety of the vehicle.

[0032] In one embodiment, the second deceleration corresponding to the parking brake information of the vehicle is acquired when it is detected that the parking brake information of the vehicle, which includes one or more of electronic parking brake system (EPB) switch information, hydraulic brake information and pedal basic brake information. The vehicle is decelerated and braked according to the first deceleration and the second deceleration.

[0033] The parking control method provided by the embodiments of the present application can be applied to a parking control device. The parking control device can be arranged in a parking control system. The parking control device can be arranged in a central computing unit of the parking control system. The parking control system can include an electronic hydraulic brake module, a central computing unit, a right domain controller, a wheel speed sensor, a brake depth sensor, an EPB switch, an execution motor and the like. The parking control system can be divided into a signal acquisition module, a control module and an execution module. The signal acquisition module mainly includes an EPB switch, a wheel speed sensor and a brake depth sensor. The EPB switch information (such as a pull-up signal), wheel speed and brake pedal depth information are acquired respectively. The information is transmitted to the central computing unit and the electronic hydraulic brake module. The central computing unit forwards the information to the right domain controller.

[0034] The principle is as shown in Figure 1 Figure 1 ​The structure schematic diagram of the parking control system provided by the embodiment of the application is shown in the figure. The central computing unit 101 is connected with the right domain controller 102 through the Ethernet 103. The electronic hydraulic brake module 104 adopts double-way controller area network (CAN) communication. One way is connected with the central computing unit 101 and the right domain controller 102 through the redundant brake sub-network 105. The other way is directly connected with the central computing unit 101 through the CAN flexible data rate (CANFD) 106. The related safety function modules (such as AEB, feedback, etc.) of the electronic hydraulic brake module 104 are integrated in the central computing unit 101 and the right domain controller 102 at the same time. When one or both of the controllers (the central computing unit and / or the right domain controller) fail, the vehicle can still be controlled to decelerate, which meets the redundant braking demand. In some embodiments, the central computing unit can also acquire the wheel speed signal through the wheel speed sensor 107 and acquire the brake pedal depth signal through the brake depth sensor 108.

[0035] The embodiment of the application acquires the wheel speed sensor signal, the EPB switch signal (i.e. EPB switch information) and the brake depth sensor signal (i.e. brake pedal depth information), and transmits them to the central computing unit 101 and the right domain controller 102. Further, the central computing unit 101 can control the corresponding first caliper motor 1011 to perform the parking action, and the right domain controller 102 can control the corresponding second caliper motor 1021 to perform the parking action.

[0036] Referring to Figure 2 , Figure 2 The flowchart of the parking control method provided by the embodiment of the application is shown in the figure. The parking control method in the embodiment can be applied to a parking control device. The parking control device includes a vehicle control unit (VCU). The method can at least include the following steps.

[0037] S201: In the case where it is detected that the brake pedal assist of the vehicle fails, acquiring the brake pedal depth information of the vehicle. The brake pedal assist failure means that the brake deceleration is less than a preset threshold.

[0038] In the embodiment of the application, the parking control device can acquire the brake pedal depth information of the vehicle in the case where it is detected that the brake pedal assist of the vehicle fails. The brake pedal assist failure means that the brake deceleration is less than a preset threshold.

[0039] In one example, when the driver steps on the brake pedal, if the brake pedal assist fails completely (completely fails to communicate, etc.) at this time, the central computing unit can provide the effective wheel speed signal and the brake pedal depth signal.

[0040] S202: Determine, by the VCU of the vehicle, a first deceleration corresponding to the brake pedal depth information according to a preset mapping relationship between depth and deceleration.

[0041] In one example, by the VCU of the vehicle, a first deceleration of -6 m / s 2 corresponding to the brake pedal depth information can be determined according to a preset mapping relationship between depth and deceleration.

[0042] S203: Decelerate and brake the vehicle according to the determined first deceleration corresponding to the brake pedal depth information.

[0043] In one embodiment, the parking control device, before obtaining the brake pedal depth information of the vehicle in the case of detecting that the brake pedal assist of the vehicle fails, can also obtain wheel speed information of the vehicle, and detect whether the wheel speed of the vehicle is greater than a wheel speed threshold according to the wheel speed information; in the case of detecting that the wheel speed of the vehicle is greater than the wheel speed threshold, the step of obtaining the brake pedal depth information of the vehicle in the case of detecting that the brake pedal assist of the vehicle fails is executed.

[0044] In one implementation, after obtaining the wheel speed and brake pedal depth information of the vehicle, the parking control device can determine, by the VCU of the vehicle, a first deceleration corresponding to the brake pedal depth information according to a preset mapping relationship between depth and deceleration; and decelerate and brake the vehicle according to the first deceleration and the wheel speed.

[0045] The embodiments of the present application utilize the wheel speed and the first deceleration corresponding to the brake pedal depth information to more accurately determine the deceleration for decelerating and braking the vehicle, so as to more effectively brake the vehicle.

[0046] Further, when decelerating and braking the vehicle according to the first deceleration and the wheel speed, the parking control device can determine a target deceleration according to the first deceleration and the wheel speed, and decelerate and brake the vehicle according to the target deceleration. When determining the target deceleration according to the first deceleration and the wheel speed, the parking control device can determine the target deceleration corresponding to the first deceleration and the wheel speed according to a preset rule. In some embodiments, the preset rule can be a preset corresponding relationship among the deceleration, the wheel speed and the target deceleration, and in other embodiments, the preset rule can be a preset calculation formula, etc.

[0047] In the embodiment of the present application, the parking control device can acquire the brake pedal depth information of the vehicle in the case of detecting that the brake pedal assist of the vehicle fails, determine the first deceleration corresponding to the brake pedal depth information according to the preset mapping relationship between the depth and the deceleration through the VCU of the vehicle, and decelerate and brake the vehicle according to the determined first deceleration corresponding to the brake pedal depth information. By using the VCU to determine the first deceleration according to the brake pedal depth information and decelerate and brake the vehicle according to the first deceleration in this way, the vehicle can be better braked, and the safety of the vehicle can be improved.

[0048] Please refer to Figure 3 , Figure 3 is a flowchart of another parking control method provided by the embodiment of the present application. As shown in the figure, the parking control method in the embodiment can be applied to a parking control device, the parking control device includes a VCU, and the method can at least include the following steps.

[0049] S301: In the case of detecting that the brake pedal assist of the vehicle fails, acquire the brake pedal depth information of the vehicle. The brake pedal assist failure refers to that the brake deceleration is less than a preset threshold.

[0050] S302: Determine the first deceleration corresponding to the brake pedal depth information according to the preset mapping relationship between the depth and the deceleration through the VCU of the vehicle.

[0051] S303: In the case of detecting the parking brake information of the vehicle, acquire the second deceleration corresponding to the parking brake information. The parking brake information includes one or more of the EPB switch information, the hydraulic brake information, and the pedal basic brake information.

[0052] In one embodiment, when the parking control device acquires the second deceleration corresponding to the parking brake information in the case of detecting the parking brake information of the vehicle, the parking control device can acquire the deceleration corresponding to the EPB switch information in the case of detecting the EPB switch information of the vehicle; and / or acquire the deceleration corresponding to the hydraulic brake information in the case of detecting the hydraulic brake information of the vehicle; and / or acquire the deceleration corresponding to the pedal basic brake information in the case of detecting the pedal basic brake information of the vehicle; and determine the second deceleration corresponding to the parking brake information according to one or more of the deceleration corresponding to the EPB switch information, the deceleration corresponding to the hydraulic brake information, and the deceleration corresponding to the pedal basic brake information.

[0053] In one example, when the parking control device acquires the EPB switch information, the parking control device can brake the caliper motor corresponding to the EPB switch to acquire the deceleration corresponding to the EPB switch information, and the highest deceleration can reach-3.4 m / s 2 .

[0054] In one embodiment, when the parking control device determines the second deceleration corresponding to the parking brake information according to one or more of the deceleration corresponding to the EPB switch information, the deceleration corresponding to the hydraulic brake information, and the deceleration corresponding to the pedal base brake information, the second deceleration can be determined according to the deceleration corresponding to the EPB switch information, the deceleration corresponding to the hydraulic brake information, and the deceleration corresponding to the pedal base brake information.

[0055] In one embodiment, when the parking control device detects that both the hydraulic brake and the EPB of the vehicle fail, the deceleration corresponding to the pedal base brake information can be determined as the second deceleration. In one example, the deceleration corresponding to the pedal base brake information can reach -4.88 m / s 2 .

[0056] S304: Decelerate the vehicle according to the first deceleration and the second deceleration.

[0057] In the embodiments of the present application, the parking control device can decelerate the vehicle according to the first deceleration and the second deceleration.

[0058] In one embodiment, the parking control device can decelerate the vehicle according to the first deceleration determined by the VCU and the second deceleration determined according to the deceleration corresponding to the EPB switch information, the deceleration corresponding to the hydraulic brake information, and the deceleration corresponding to the pedal base brake information.

[0059] In one embodiment, the parking control device can decelerate the vehicle according to the first deceleration determined by the VCU and the second deceleration determined according to the deceleration corresponding to the EPB switch information and the deceleration corresponding to the hydraulic brake information.

[0060] Specifically, the second deceleration can be determined according to the deceleration corresponding to the EPB switch information, the deceleration corresponding to the hydraulic brake information, and the deceleration corresponding to the pedal base brake information. Figure 4 For example, the second deceleration can be determined according to the deceleration corresponding to the EPB switch information and the deceleration corresponding to the hydraulic brake information. Figure 4 is a structural diagram of deceleration braking provided by the embodiments of the present application, as shown in Figure 4As shown, the deceleration braking includes VCU 401, EPB 402, hydraulic brake 403, wherein VCU 401 can send a brake request to hydraulic brake 403, and hydraulic brake 403 can send feedback information of participating braking to VCU 401 in response to the brake request sent by VCU 401; VCU 401 can also send a brake request to EPB 402, and EPB 402 can respond to the brake request sent by VCU 401 by sending a dynamic brake instruction to hydraulic brake 403, so that hydraulic brake 403 sends feedback information to VCU 401. The feedback information can include but is not limited to wheel speed, EPB switch information, hydraulic brake information, etc. The first deceleration, the deceleration corresponding to the EPB switch information, and the deceleration corresponding to the hydraulic brake information can be determined by the feedback information obtained by the VCU according to the embodiments of the present application, and the corresponding second deceleration can be determined according to the deceleration corresponding to the EPB switch information and the deceleration corresponding to the hydraulic brake information.

[0061] In one embodiment, the parking control device can calculate the sum of the first deceleration and the second deceleration when decelerating the vehicle according to the first deceleration and the second deceleration; and decelerate the vehicle according to the sum of the first deceleration and the second deceleration.

[0062] For example, it is assumed that the first deceleration determined by the VCU is -6 m / s 2 , the deceleration corresponding to the EPB switch information is -3.4 m / s 2 , and the deceleration corresponding to the hydraulic brake information is -5 m / s 2 , then the corresponding second deceleration can be determined as -8.4 m / s 2 according to the deceleration corresponding to the EPB switch information and the deceleration corresponding to the hydraulic brake information, and further the sum of the first deceleration -6 m / s 2 and the second deceleration -8.4 m / s 2 is -14.4 m / s 2 .

[0063] In one embodiment, the parking control device can also obtain the wheel speed of the vehicle, and decelerate the vehicle according to the wheel speed of the vehicle, the first deceleration and the second deceleration. Alternatively, the parking control device can determine the deceleration corresponding to the wheel speed of the vehicle, the first deceleration and the second deceleration according to a preset strategy, and decelerate the vehicle according to the determined deceleration corresponding to the wheel speed of the vehicle, the first deceleration and the second deceleration.

[0064] In the embodiment of the present application, the parking control device can acquire brake pedal depth information of the vehicle in the case that brake pedal assist failure of the vehicle is detected, determine a first deceleration corresponding to the brake pedal depth information according to a preset mapping relationship between depth and deceleration through the VCU of the vehicle, acquire a second deceleration corresponding to the parking brake information of the vehicle in the case that the parking brake information of the vehicle is detected, and decelerate and brake the vehicle according to the first deceleration and the second deceleration. In this way, the combination of multiple braking modes helps to better brake the vehicle and further improve the safety of the vehicle.

[0072] In one example, the parking control device obtains a deceleration -8.28 m / s 2 corresponding to the pedal basic braking information when it is detected that the brake pedal boost, VCU, hydraulic brake and EPB of the vehicle are all failed; and brakes the vehicle at a deceleration -4.88 m / s 2 corresponding to the pedal basic braking information.

[0073] In one embodiment, the parking control device can also obtain the wheel speed of the vehicle, and brake the vehicle at a deceleration according to the wheel speed of the vehicle and the deceleration corresponding to the pedal basic braking information.
