Abstract
When a turning state of a subject vehicle is detected, the action timing of the contact avoidance support device is slower than when the turning state is not detected. When an action timing determining part 22 estimates that there is the possibility of the subject vehicle coming into contact with the vehicle in front and a turning state of the subject vehicle is detected based on the output from a transversal acceleration sensor S4, a changing rate of the steering angle sensor S5, and a yaw rate sensor S3, a compensation interval calculating part 23 calculates a compensation interval depending on the size of the detected turning state (the amount of the steering angle, the changing rate of the steering angle, and the transversal acceleration). The action timing of the brake actuator 12 is slowed by this compensation interval.
