Integrated control apparatus for vehicle

摘要

In a vehicle of a four-wheel independent steering type, an electronic control unit calculates a target yaw rate in accordance with a vehicle speed and a steering angle, and calculates a vehicle-control target value on the basis of the target yaw rate and an actual yaw rate. The electronic control unit estimates the grip factors of the individual wheels to road surface, and sets a distribution ratio for distribution of the vehicle-control target value among actuators of a steering system, a brake system, and a drive system in accordance with the estimated grip factors. The electronic control unit controls the actuators of the three systems in accordance with control instruction values determined on the basis of the vehicle-control target value and the distribution ratio.
