Abstract:

The driver maneuver intention and its urgency level are characterized based on the angular speed of steering wheel and the low pass characteristic of vehicle.With the corrected method,the reference model of ESP has been corrected,which make the ESP intervene more properly.The ESP with the corrected method can not only improve the response behavior of vehicle,but also avoid the disturbance to driver caused by the ESP which would get involved at a bad time.The effect of the corrected method is validated with the field experiment results of a vehicle equipped with ESP.

Key words: vehicle engineering, vehicle response performance, steering urgency intention, ESP reference model correction, steer wheel angle gradient
