Abstract:

The kinematic behavior of the car in the lowspeed backup process and the collision possibility between the car body and the obstacle in the parking space were analyzed, and the starting area for the backup under parallel parking condition was determined according to the backup path from the geometric constrains of the car body by the parking space. A steering strategy for the parallel parking was realized to trace the planned path to avoid collision. A kinematic model was built for a certain car in SIMULINK to simulate the car backup environment of parallel parking. The parallel parking process of the car was simulated by introducing the steering control strategy into the system built using SIMULINK. The simulated results verified the feasibility to realize the parallel parking by the proposed strategy.

Key words: vehicle engineering, parallel parking, pathplanning, collisions analysis, simulation
