The present invention provides a braking system and a braking method. The system includes a master controller, a slave controller, a first actuator corresponding to the master controller, and a second actuator corresponding to the slave controller. The master controller can monitor the working status of the power system controller, steering system controller, parking system controller and slave controller, and control any one or more of the power system controller, steering system controller, and parking system controller. When the slave controller is in an error state and the slave controller is in a normal state, a first braking command is sent to the slave controller. The slave controller can monitor the working state of the master controller, and control the second actuator to perform a braking operation based on the first braking command when the master controller is in a normal state. Based on the redundant controller design of the present invention, the monitoring of key electronic devices of the vehicle and the mutual monitoring of the master-slave controllers can be realized, so as to deal with the safety risks caused by electronic and electrical faults that may occur in unmanned parking.
Description
technical field [0001] The invention relates to the technical field of automobiles, more specifically, to a braking system and a braking method. Background technique [0002] The braking system of modern vehicles has been electronically electrified. The control unit of the braking system collects the driver's intention and necessary sensor information, and then controls the execution unit in the system accordingly to generate the required braking force to ensure that the vehicle decelerates and stops safely according to the driver's intention. [0003] However, when applied to unmanned parking, since the vehicle needs to complete actions such as searching for a parking space, parking and parking without a driver, once the key electronic device of the vehicle, such as the central controller of the parking system, fails, existing The design of the brake system control unit will not be able to cope with possible safety risks. Contents of the invention [0004] In view of th...
