Abstract
An appropriate deceleration is achieved. A brake control apparatus is a brake control apparatus which performs a brake assist control for assisting a brake operation by a driver of a vehicle, the brake control apparatus is provided with: a calculating device which calculates a contact possibility of the vehicle contacting the obstacle; and a changing device which changes, on the basis of the contact possibility, a decreasing rate of a deceleration of the vehicle caused by the brake assist control.
Claims15
A brake control apparatus which performs a brake assist control for assisting a brake operation by a driver of a vehicle when an obstacle exists anterior to the vehicle, the brake control apparatus comprising:
- a controller configured to:
- calculate a contact possibility of the vehicle contacting the obstacle;
- change, on the basis of the contact possibility, a decreasing rate of a deceleration of the vehicle caused by the brake assist control, when the deceleration of the vehicle decreases as time passes regardless of the brake operation by the driver;
- and
- change the decreasing rate of the deceleration such that the higher the contact possibility is, the smaller the decreasing rate of the deceleration is.
A brake control apparatus which performs a brake assist control for assisting a brake operation by a driver of a vehicle when an obstacle exists anterior to the vehicle, the brake control apparatus comprising:
- a controller being configured to:
- calculate a contact possibility of the vehicle contacting the obstacle;
- and
- change at least one of a decreasing rate of a first deceleration and an increasing rate of a second deceleration such that the higher the contact possibility is, the larger an absolute value of a difference between the decreasing rate of the first deceleration and the increasing rate of the second deceleration, when the deceleration of the vehicle changes as time passes regardless of the brake operation by the driver, wherein
- the first deceleration is a deceleration of the vehicle when the brake assist control is performed such that the deceleration decreases as time passes, the second deceleration is a deceleration when the brake assist control is performed such that the deceleration increases as time passes.
