Research on Longitudinal Control Mechanism of Fully Automatic Parking Based on Dual Clutch Transmission
Wang Shaozhang Ren Weidong Li Penglong
Abstract：Vehicle longitudinal control refers to the motion control of the vehicle in the forward/reverse direction， including torque control， clutch control， gear control， and brake control. The longitudinal control of the vehicle in the automatic parking process belongs to the category of low-speed control， and the control is more difficult. Especially for fully automatic parking systems that match dual-clutch transmissions， the associated controllers of the longitudinal control have problems such as conflicting control strategies and difficulty in system integration and matching. It is necessary to systematically study the relevant longitudinal control mechanism to optimize the system integration and matching scheme to meet the requirements of the automatic parking system for longitudinal control.
