A fault-tolerant control method for actuator failure in an electric vehicle stability system includes the following steps: collecting vehicle driving state and actuator information; constructing a vehicle driving state feasible region using the tire force feasible region and the friction circle guidance range; calculating reference values ​​of state variables based on a vehicle reference model; using the reference values ​​and actual values ​​of the state variables as inputs to the upper-level vehicle motion controller; obtaining the resultant force and resultant torque of the current operating condition under the constraints of the vehicle driving state feasible region by model predictive control; allocating tire force under the constraints of the tire force feasible region; introducing tire force changes caused by actuator failure into the vehicle dynamic controller reconstruction; firstly obtaining the fault-tolerant feasible region of tire force and the fault-tolerant feasible region of the vehicle driving state after the failure; using the fault-tolerant feasible region as a new constraint for fault-tolerant control; finally, for situations where fault-tolerant control cannot control, reshaping the reference input to ensure the vehicle can drive safely to the maximum extent.

The application provides a vehicle carrying device with a buffer structure for a stereo garage and the stereo garage. The vehicle carrying device comprises a vehicle carrying plate, a front end and a rear end opposite to the front end; a guide slope pivotally connected to the front end and the rear end of the vehicle carrying plate respectively, each guide slope having an inclined top surface and a bottom opposite to the top surface; and a first buffer pad arranged at the bottom of the guide slope, the bottom of the first buffer pad protruding from the bottom of the guide slope, and the first buffer pad being capable of rotating. When a vehicle drives into / out of the vehicle carrying plate, the first buffer pad provided by the application can rotate adaptively with the change of the angle of the supporting surface, so that the first buffer pad always keeps in close contact with the supporting surface, thereby being capable of absorbing impact force from different directions and reducing noise and vibration generated by rigid collision.
