ABSTRACT:
In a vehicle collision preventing system, a possibility of collision of a subject vehicle against an object ahead of the subject vehicle is determined at least based on values measured by a distance measuring unit for measuring longitudinal and lateral distances between the subject vehicle and the object and a value detected by a subject-vehicle speed detecting device, an actuator is operated in accordance with the result of such determination to avoid the collision. A lateral relative distance of the subject vehicle and the object is calculated by a lateral relative distance calculating device based on the values measured in the distance measuring unit. Any of a judge level in the judgment of the collision possibility in a judging device or operation levels of actuators is changed in accordance with the result of the determination in a collision avoidance level determining device based on the lateral relative distance. Thus, the actuators are operated in accordance with a variation in lateral relative distance between the subject vehicle and the object, so that the collision preventing operations of the actuators are more easily accepted by a driver.
