Title: Vehicle travel safety device

Abstract: The operational burden and uncomfortable feeling given to a driver by automatically restoring the disturbance in the vehicle attitude of a vehicle caused by a collision avoidance control, is reduced when avoiding a collision between the vehicle and an oncoming vehicle by automatic steering. When there is a possibility of a collision between the vehicle and an oncoming vehicle, the collision with the oncoming vehicle is avoided by supplying a lateral movement control current I.sub.1 having a sinusoidal shape to the actuator of the electric power steering device, to move the vehicle laterally. The yaw angle of the vehicle is detected by integrating the yaw rate simultaneously with the start of the lateral movement, and in order to return the vehicle attitude of the vehicle to its original state by converging the yaw angle to 0 in the final stage of the lateral movement, a yaw angle correction control current I.sub.2 is superimposed on the lateral movement control current I.sub.1 and supplied to the actuator. Thus, after avoiding a collision with the oncoming vehicle, the disturbance in the vehicle attitude can automatically be restored and the operational burden and uncomfortable feeling given to the driver can be reduced.
