[0023] Figure 1 A schematic structural diagram of a parking control system provided in an embodiment of the utility model. DETAILED DESCRIPTION

[0024] The specific implementation methods of the present utility model will be further explained in detail below by describing the optimal embodiments with reference to the accompanying drawings.

[0025] Figure 1 This is a schematic diagram of the structure of a parking control system provided by an embodiment of the utility model. For the sake of convenience, only the parts related to the embodiment of the utility model are shown. The system includes:

[0026] The parking switch, EPB controller and electronic caliper are located on the IHU interface;

[0027] The parking switch is connected to the EPB controller in communication, and the EPB controller is connected to the electronic caliper in communication;

[0028] When the parking switch issues a parking command, the EPB controller sends the parking command to the electronic caliper, and the electronic caliper performs a clamping operation to perform a parking clamping operation; when the parking switch issues a brake release command, the EPB controller sends the brake release command to the electronic caliper, and the electronic caliper performs a release operation to perform a brake release operation.

[0029] The utility model adopts a parking switch to control the parking of the vehicle, which reduces the cost of the vehicle and makes the space of the central control instrument panel of the vehicle compact and beautiful.

[0030] In an embodiment of the utility model, the system further comprises:

[0031] The in-vehicle infotainment system communicates with the IHU interactive interface;

[0032] After the electronic caliper has performed the clamping operation, the in-vehicle infotainment system sets the state of the parking switch to highlighted white; after the electronic caliper has performed the releasing operation, the in-vehicle infotainment system sets the state of the parking switch to blue; the different states of the parking switch are used to more intuitively remind the driver and passengers of the current parking status.

[0033] In order to further attract the attention of the driver and passengers, when the state of the parking switch is set to highlighted white, the IHU interactive interface displays the text prompt "Caliper clamped". When the state of the parking switch is set to blue, the IHU interactive interface displays the text prompt "Caliper released".

[0034] In an embodiment of the utility model, the system further comprises:

[0035] Parking hard switch, communicating with the EPB controller;

[0036] When the parking hard switch issues a parking command, the EPB controller sends the parking command to the electronic caliper, which performs a clamping operation to perform the parking clamping operation; when the parking hard switch issues a brake release command, the EPB controller sends the brake release command to the electronic caliper, which performs a release operation to perform the brake release operation. By setting two parking switches, the two parking switches are redundant to each other. When one of the parking switches fails, the other parking switch can be used to park and release.

[0037] In an embodiment of the utility model, the system further comprises:

[0038] Transmission controller TCU, brake travel sensor and vehicle speed sensor on the brake pedal;

[0039] The transmission controller TCU, brake travel sensor and vehicle speed sensor are connected to the vehicle infotainment system;

[0040] The transmission controller TCU outputs the gear signal, the dynamic travel sensor outputs the braking travel of the brake pedal, and the speed sensor outputs the vehicle speed. When the vehicle is in the ignition state, the gear signal output by the transmission controller TCU is not the P gear, the brake pedal is in the braking state, and the vehicle speed is greater than the vehicle speed threshold, the in-vehicle infotainment system sets the parking switch to the activated state, otherwise the parking switch is set to the disabled state to avoid conflicts between the parking commands of the two parking switches. Only the parking switch in the activated state can perform the vehicle parking operation. In order to facilitate the driver and passengers to understand the state of the parking switch, when the parking switch is in the activated state, the state of the parking switch is set to dark gray, and when the parking switch is in the disabled state, the state of the parking switch is set to light gray.

[0041] An embodiment of the utility model further provides a vehicle, on which the above parking control system is integrated, and the parking operation of the vehicle is controlled by the above parking control system.

[0042] The utility model has been described exemplarily. Obviously, the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made by adopting the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
