Abstract

Focus on the hill-start auto control technology of the medium and heavy duty vehicles, structure of the spring brake cylinder and principle of the pneumatic auto parking brake system were analyzed. The force analysis of the vehicles which is on the hill was researched. The relationships between the driving force, the braking force and the grade resistance in the process of hill start were analyzed. The release time of the driving force was the key of hill-start control, and it influenced the process of hill start. The ideal control curve of the hill-start auto control was raised, and the release time of the parking brake was the time that the braking force could overcome the grade resistance. The control strategies of the pneumatic auto parking brake system were designed for the hill start, and the control software was written. The test vehicle was refitted, and the control strategy and software were written. The feasibility of the control strategy and software was proved on the test vehicle.
