Detailed Description
As shown in fig. 2, the parking control device comprises a vehicle communication data bus 7, a parking brake actuator 3, a first parking brake controller 1 and a second parking brake controller 6, wherein the vehicle communication data bus 7 is used for receiving vehicle related information and issuing parking state information to the whole vehicle; the parking brake actuator 3 is integrated with the brake caliper 4 and is used for executing parking brake on the wheel; the first parking brake controller 1 is connected with a vehicle communication data bus 7; a second parking brake controller 6, the input end 611 of which is connected to the first parking brake controller 1, and the output end 612 of which is connected to the parking brake actuator 3, i.e. the parking brake actuator 3 is connected to the first parking brake controller 1 via the second parking brake controller 6; the second parking brake controller 6 is connected to a vehicle communication data bus 7. The existing non-parking brake controller is expanded by adding the minimum number of required electronic components to serve as a second parking brake controller. When the first parking brake controller, which is the main control, malfunctions and it is detected that the driver intends to apply or release the parking brake, the second parking brake controller may operate the parking brake actuator.
The second parking brake controller 6 may be a brake booster or a gearbox controller or a vehicle controller. The second parking brake controller 6 may collect information via the vehicle communication data bus 7, determining driver intent via gear, engine speed and clutch.
As shown in fig. 3, in order to avoid interference with the output of the first parking brake actuator during operation of the parking brake actuator by the second parking brake controller, the second parking brake controller 6 includes a first switch circuit 65, a second switch circuit 67 and a processor 66, the second switch circuit 67 is provided between an input 611 and an output 612 of the second parking brake controller for cutting off control of the parking brake actuator 3 by the first parking brake controller 1 such that the first parking brake actuator 1 is disabled during operation of the parking brake actuator 3 by the second parking brake controller 6, the input 611 and the output 612 of the second parking brake controller are connected to the vehicle communication data bus 7 through the first switch circuit 65, the first switch circuit 65 is controlled by the processor 66, i.e. the second parking brake controller 6 supplies electric power to the parking brake actuator 3 through the closed first switch circuit 65 and the processor 66, thereby effecting release or application of the parking brake.
The first embodiment is as follows: as shown in fig. 4, the parking control apparatus further includes a parking brake switch 2, the parking brake switch 2 is connected to the first parking brake controller 1, the first parking brake controller 1 detects the state of the parking brake switch, and issues the state of the parking brake switch through a vehicle communication data bus 7. When the parking brake switch 2 or the first parking brake controller 1 fails, while the driver intends to apply or release the parking brake, the second parking brake controller 6 receives a signal issued from the vehicle communication data bus 7, and takes over the operation of the parking brake actuator 3.
