Abstract
The present invention is to enhance safety of a vehicle by avoiding excessive approaches and collisions with preceding vehicles without spoiling a drive feeling of a driver by controlling the vehicle by, for example, initializing CPU and RAM in Step 201, operating a velocity and an acceleration of an own vehicle, following-on ranges from the preceding vehicles, relative velocities, a variable amount of steering angle, the amount of stepping brake from various sensor outputs in Step 202, judging an unconsciousness such as dozing from the variable amount of the steering angle in Step 203, obtaining an approach index expressing degrees of approaching to the preceding vehicles in Step 205, operating a target braking force by the amount of stepping brake pedal and controlled variables corresponding to the approach index based on the following-on ranges or the like when the driver is judged to be dozing in a case of excessively approaching in Step 205, and controlling the own vehicle by outputting these results of operation, wherein a braking force corresponding to an ordinary amount of stepping brake is applied when the driver is not unconscious and the vehicle does not excessively appr…
