Parking mechanism is a critical safety device in automatic vehicle transmission. Its safety features give a good indication of safety performance of AT vehicle. This chapter takes the parking mechanism on 7-speed dual clutch transmission as an example, uses kinematics theory to analyze difference of travel times between parking pawl and parking gear. In order to verify the safety performance at high speed parking, a rigid-flexible coupling multi-body dynamic model is established with ADAMS software, based on which the non-linear analysis is conducted to key components of the parking mechanism with peak impact load at high speed parking as input. In addition, through combining mechanics theory and kinematics simulation, the critical friction coefficient is estimated from the aspect of self-locking performance, which serves as references for future design of parking mechanism.
