Research for Cornering Gearshift Strategy of Automatic Transmission Vehicles Based on Fuzzy Inference

Abstract:

Undesired gearshift often occurred when the vehicle was under the curve driving condition. To resolve this problem, this paper proposed a fuzzy correction gearshift strategy under cornering which put the lateral acceleration and lateral acceleration variation rate, the external load and the real-time vehicle speed as parameters. Road test results showed that the undesired gear shift frequency was largely reduced and this method improved driving comfort and security under cornering condition.
