Braking device for vehicle
A braking device for a vehicle comprises an accelerator-opening detector, a distance detector, an obstacle detector, and an ECU which is configured to perform the process of executing automatic braking when the distance detected by the distance detector is a specified distance or less during traveling of the vehicle, cancelling the automatic braking when the accelerator opening detected by the accelerator-opening detector is a specified opening or greater, and prohibiting the cancelling of the automatic braking when the front obstacle is detected by the obstacle detector while the vehicle stops or travels at a low speed which is a specified speed or less. Thereby, the braking device for a vehicle which can surely reduce the damage caused by the vehicle's collision with the front obstacle can be provided.
1. A braking device for a vehicle, comprising:
a vehicle-speed detector to detect a vehicle speed of the vehicle;
an accelerator-opening detector to detect an accelerator opening of the vehicle;
a distance detector to detect a distance between the vehicle and a front obstacle;
an obstacle detector to detect the front obstacle;
a brake adjustor to adjust a breaking force applied to a brake device of the vehicle; and
a controller to control the brake adjustor based on detections of the vehicle-speed detector, the accelerator-opening detector, the distance detector, and the obstacle detector,
wherein said controller is configured to perform the process of:
executing automatic braking when the distance detected by said distance detector is a specified distance or less during traveling of the vehicle;
cancelling said automatic braking when the accelerator opening detected by said accelerator-opening detector is a specified opening or greater; and
prohibiting said cancelling of the automatic braking when the front obstacle is detected by said obstacle detector while the vehicle stops or travels at a low speed which is a specified speed or less despite the accelerator opening being the specified angle or greater, but not prohibiting said cancelling of the automatic braking while the vehicle travels at a high speed which is greater than the specified speed so as to cancel the automatic braking.
2. The braking device for a vehicle of claim 1 , wherein said controller is further configured to perform the process of:
counting how many times the automatic braking is executed when said cancelling of the automatic braking is prohibited; and
not prohibiting the cancelling of the automatic braking when said counted times is a specified time or greater.
3. The braking device for a vehicle of claim 1 , wherein said controller is further configured to perform the process of:
measuring the time how long said cancelling of the automatic braking is prohibited; and
not prohibiting the cancelling of the automatic braking when said measured time is a specified time or greater.
4. The braking device for a vehicle of claim 2 , wherein said controller is further configured to perform the process of:
measuring the time how long said cancelling of the automatic braking is prohibited; and
not prohibiting the cancelling of the automatic braking when said measured time is a specified time or greater.

a controller to control the brake adjustor based on detections of the accelerator-opening detector, the distance detector, and the obstacle detector,
wherein said controller is configured to perform the process of:
executing automatic braking when the distance detected by said distance detector is a specified distance or less during traveling of the vehicle;
cancelling said automatic braking when the accelerator opening detected by said accelerator-opening detector is a specified opening or greater;
prohibiting said cancelling of the automatic braking when the front obstacle is detected by said obstacle detector while the vehicle stops or travels at a low speed which is a specified speed or less;
counting how many times the automatic braking is executed when said cancelling of the automatic braking is prohibited; and
not prohibiting the cancelling of the automatic braking when said counted times is a specified time or greater.
