Xiaomi applied for a patent for "vehicle drift control method, device, vehicle, storage medium and chip"

The patent of "vehicle drift control method, device, vehicle, storage medium and chip" applied by Xiaomi Automobile Technology Co., Ltd. was recently published.

The abstract shows that the method includes: when the vehicle is in the drift mode open state, obtain the slip rate level and steering information of the vehicle and the current vehicle speed of the vehicle, determine the target drift parameters, and the target drift parameters include the target yaw rate; according to the current vehicle speed The actual yaw rate and the target yaw rate determine the amount of steering compensation; according to the amount of steering compensation and steering information, determine the front axle torque, rear axle torque and rear wheel braking torque of the vehicle, so as to control the drifting of the vehicle. During the process, the steering compensation is performed by controlling the power steering motor according to the steering compensation amount and vehicle speed.

The disclosure reduces the dependence of vehicle drift on the driver, and determines different drift parameters according to different steering and vehicle speeds of the vehicle, so as to realize drift in different states.
