Vehicle motion control device
First Claim
1. A vehicle motion control device including:
- obstacle recognition means for recognizing an obstacle of the vehicle by detecting information of the obstacle;
vehicle running condition detecting means for detecting running condition of the vehicle;
vehicle behavior control means for controlling a vehicle behavior by varying a turning-round performance of the vehicle;
avoidance control means for controlling the vehicle behavior control means so as to set the vehicle behavior into an obstacle avoidance traveling mode;
avoidance operation detecting means for detecting an avoidance operation of the vehicle against the obstacle;
steering operation detecting means for detecting whether a steering operating mount is equal to or greater than a predetermined value or not; and
vehicle behavior detecting means for detecting the vehicle'"'"'s understeer state and oversteer state based on the running condition;
wherein the avoidance control means controls the vehicle behavior control means so as to vary the turning-round performance in the obstacle avoidance mode according to vehicle'"'"'s understeer state and oversteer state when the steering operating mount is equal to or greater than the predetermined value and the avoidance operation is performed.

Abstract
A vehicle motion control device is provided which can pre-determine an obstacle ahead of the vehicle and adequately reflect the vehicle operator'"'"'s maneuver and intention in consideration of various travel information throughout an avoidance travel, thereby allowing each vehicle behavior controller to naturally provide adequate control for the vehicle to avoid the obstacle. During the avoidance travel mode, the device allows a vehicle behavior control section to provide necessary control in response to a change in steering operation and vehicle behavior. The avoidance travel mode is released when the steering operation by the vehicle operator causes the end of the avoidance travel to be detected or when the stability of the vehicle behavior is detected after the obstacle has been avoided.
