ALARM SYSTEM AND ALARM METHOD FOR VEHICLE

摘要

A collision probability index value corresponding to a probability of collision between a host vehicle and an obstacle is calculated based on the information indicating the relative relationship between the host vehicle and the obstacle; and the alarming braking operation is performed to cause a driver to recognize that a collision may occur by changing at least one of the drive power and the braking force when the collision probability index value reaches a predetermined threshold value. In the alarming braking operation, a target acceleration that is used as a target value in the alarming braking operation is set based on the acceleration of the host vehicle, which is detected when the collision probability index value reaches the predetermined threshold value; and at least one of the drive power and the braking force is controlled so that the target acceleration is achieved.
