The invention discloses a control method for the automatic parking torque of an electric automobile, which comprises the following steps of: determining the highest speed of automatic parking, and detecting and obtaining the target speed of automatic parking; obtaining the corresponding highest automatic parking driving torque according to the highest vehicle speed; obtaining basic driving torqueof the target vehicle speed according to the target vehicle speed, the highest vehicle speed and the highest automatic parking driving torque; carrying out automatic parking based on the basic drivingtorque. The problems that in the prior art, due to the fact that torque control is not accurate enough, the parking position of a vehicle is not well controlled in the automatic parking process, andeven the vehicle is scratched with other objects in the parking process can be solved.
本发明公开了一种电动汽车自动泊车扭矩的控制方法,包括以下步骤:确定自动泊车的最高车速,并检测获取自动泊车的目标车速;根据最高车速获得对应的最高自动泊车驱动扭矩;根据目标车速、最高车速以及最高自动泊车驱动扭矩获得目标车速的基础驱动扭矩,基于基础驱动扭矩来自动泊车可以避免现有技术中因为扭矩控制不够准确而导致车辆在自动泊车过程中泊车位置控制不佳,甚至会在泊车过程中出现与其他物体出现刮蹭的问题。
