摘　　要：车辆扭矩控制是指控制车辆前进、后退、转弯时提供适当且不造成过大或者过小的扭矩,包括制动系统控制扭矩、转向系统控制扭矩、离合变速系统控制扭矩以及车身电气供电转换扭矩。高级智能驾驶自动泊车功能在其运行过程中,涵盖了上述所有扭矩,在扭矩控制策略上匹配优化各模块间相关协调、解决策略冲突问题,满足自动泊车系统平稳、安全、鲁棒性高的控制要求。Vehicle torque control refers to the control of the vehicle forward,backward,turning to provide appropriate and not cause too much or too small torque,including braking system control torque,steering system control torque,clutch transmission system control torque and body electric power supply conversion torque.The automatic parking function of advanced intelligent driving covers all the torques above in its operation process.It matches and optimizes the relevant coordination between the modules in the torque control strategy,and solves the policy conflict,and meets the control requirements of the automatic parking system with stability,safety and high robustness.
