Abstract

The improvement of drivability is a key factor to enhance the quality of a car. The gap is an inevitable factor in driveline which has influence on drivability. So it is necessary to study the influence of the gap on drivability. By setting up a low-frequency longitudinal vehicle dynamics model to simulate the tip-in drive condition which has bad drivability, the influence of gap on the car's drivability was studied. It included the impact of clearance gaps at different locations and different gap size on drivability. And it got some useful rules to control-oriented modeling. Further studies of the problem when the vehicle there is a big gap and using the methods of classical ‘torque slope control’ to improve drivability. In order to solve this problem, a closed-loop controller was designed and the car’s drivability was improved.

Key words
