Collision avoiding system for vehicles
First Claim
1. A vehicular collision avoiding system, comprising:
- obstacle detecting means for detecting an obstacle located ahead of the vehicle;
a braking system for braking the vehicle;
brake control means for controlling the operation of the braking system on the basis of a relative distance and a relative speed between the obstacle detected by the obstacle detecting means and the vehicle; and
a steering system for steering the vehicle comprising steering controlling means coupled to the brake control means, said steering control means outputting a steering command signal to control the operation of the steering system on the basis of a braking command signal outputted by the brake control means, so as to suppress the influence of disturbances caused by the operation of the braking system.

Abstract
A collision avoiding system is provided to enhance a collision avoiding effect by stabilizing a vehicle behavior during automatic braking. Steering controlling apparatus includes not only an ordinary electric power steering control unit but also an active steering reaction calculating unit for driving a motor of a steering system to compensate for the influence of disturbances, if the vehicle is shocked by an unusual bounce from an uneven road or the like. When obstacle detecting apparatus such as a laser-radar detects an obstacle which requires operation of automatic braking, a control parameter changing unit receives the automatic braking activating signal to make a change in the control parameters for an active steering reaction control. As a result, the steering control apparatus controls steering to suppress the influence of the disturbances more substantially during automatic control of the vehicle than otherwise, so that the turbulence of the vehicle can be prevented to retain a sufficient braking force, thereby enhancing the collision avoiding effect.
