VEHICLE ATTITUDE CONTROL DEVICE

摘要

PROBLEM TO BE SOLVED: To stabilize the behavior of a vehicle by controlling the steering angle and the braking force in the vehicle in an understeer condition. SOLUTION: The steering correction behavior index is determined so that the difference between the target behavior index of the vehicle and the steering correction behavior index becomes small when the instability index correlated to the understeer degree is increased, and the steering correction behavior index is equal to the behavior index when the target behavior index is equal to the behavior index. The braking correction behavior index is determined so that the difference between the target behavior index and the braking correction behavior index is increased when the instability index is increased, and the braking correction behavior index is equal to the behavior index when the target behavior index is equal to the behavior index. In the understeer condition, a steering actuator M and the braking force are controlled so that the steering correction behavior index and the braking correction behavior index follow the target behavior index.
