Abstract
A collaborative control scheme between engine and automatic transmission (AT) gearbox is proposed to realize a smoother gear shifting for improving riding comfort. A systematic procedure is developed to obtain a desired engine torque profile and a desired hydraulics actuation profile for the AT gearbox which will minimize shocks due to gear shifting. Tracking controls must be applied to both the engine and the AT gearbox to follow these profiles. For the model-based approach, an AT gearbox model is devised using hybrid systems techniques to represent the discrete-event nature of automatic transmissions. Numerical evaluations have shown the effectiveness of the proposed scheme.
