Abstract
An integrated vehicle control system including: contact possibility determining means for determining whether a possibility of contact with an obstacle is great, first brake control means for controlling operation of the vehicle brake in response to the possibility of contact, vehicle behavior detecting means for detecting parameters such as the vehicle yaw rate, vehicle behavior control means for calculating a value such as the error between the detected yaw rate and a reference yaw rate and calculating a manipulated variable (braking force difference) to make vehicle behavior stable, and second brake control means for controlling operation of the vehicle brake in response to the calculated manipulated variable. In the system, the vehicle behavior control means advances the timing of the calculation of the manipulated variable or increases the manipulated variable, when the possibility of contact is great, whereby effecting the vehicle behavior sufficient for avoiding an obstacle, while ensuring stable vehicle behavior.
