Abstract

The invention provides a method and apparatus for automatic parking torque control. The method includes the steps of acquiring a parking instruction, acquiring a vehicle speed at a current time of thevehicle; obtaining the target acceleration at the next time; calculating a target output torque of the vehicle at the next time matching the target acceleration at the next time according to the vehicle speed at the current time and the target acceleration at the next time; and calculating the actual output torque of the vehicle at the next time according to the target output torque at the next time. The automatic parking torque control method of the invention is simple and easy to operate, does not need a lot of debugging and calibration work, and has low input cost.

Description

technical field [0001] The invention relates to the technical field of new energy vehicle controllers, in particular to an automatic parking torque control method and device. Background technique [0002] At present, the automatic parking control of electric vehicles usually adopts a torque control method based on vehicle speed, adopts PID control, or adds some compensation methods or parameter optimization methods on the basis of PID control. [0003] However, when PID control technology is used to control vehicle speed, the parameter configuration of PID basically depends on a lot of manpower and time to debug. poor reusability. Contents of the invention [0004] In view of this, the present invention provides an automatic parking torque control method and device, so as to reduce the investment cost of the scheme of controlling the vehicle torque during the automatic parking process, and improve the reusability of the technology at the same time. [0005] To achieve th...
