VEHICULAR INTEGRATED CONTROL DEVICE

Japanese Patent JP2005112007

A

To provide a vehicular integrated control device capable of enhancing the vehicular stability by integrally controlling each actuator of a steering system, a control system and a drive system at an optimum distribution according to the vehicular behavior condition and a road surface condition without using any road surface friction coefficient.

An electronic control device 11 operates the target yaw rate according to the vehicle speed V and the steering angle, and operates the yaw rate deviation based on the target yaw rate and the actual yaw rate. The electronic control device 11 estimates the grip degree of front wheels to the road surface, and sets the distribution ratio of the target vehicular control value to the actuators of a steering system, a braking system and a driving system according to the grip degree. In addition, the electronic control device 11 controls the actuators of the three systems according to the control command values distributed according to the distribution ratio.
