Some approaches to emulating an expert drivers longitudinal and lateral integrated control using jerk information are studied in this paper. A trade off strategy between longitudinal traction versus cornering traction was extracted experimentally by using jerk information to observe voluntary braking and turning during driving. The strategy is realised by determining the longitudinal acceleration command during combination motion by vehicle lateral jerk. The vehicle dynamical rationally of the method is also evaluated by computer simulation in view of instantaneous handling characteristics. Applying the strategy we made a longitudinal driver model that works in coordination with any steering input. Adopting a programmed handling model and a pieview follower model for the steering input we carried out computer simulation. We also earned out cornering and braking lane-change experiments with an expert driver. The simulation results and experimental results agree well and we confirm that the model can emulate a certain part of the expert drivers control strategy for trading off longitudinal and lateral accelerations.
