BRAKE CONTROLLER OF VEHICLE

摘要

If a radar (S1) on a vehicle having a brake controller detects an object in front of the vehicle, a judging means (M1) estimates the possibility that the vehicle may hit the object from the relative position between the vehicle and the object based on the detection result. If it is judged that there is a possibility of the hitting, an automatic braking means (M2) instructs a negative pressure booster (2) to perform automatic braking so as to avoid the hitting the object. If a braking intention detecting means (M3) detects the braking intention of the driver while the automatic braking means (M2) is performing the automatic braking, an urgency estimating means (M4) estimates the urgency of the braking by the driver, and the automatic braking means (M2) generates a braking force corresponding to the urgency to assist the braking by the driver. Thus, the transition from automatic braking for avoiding a hitting to manual braking by the driver is smooth and, further, a strong breaking force assisted by the automatic braking is generated to avoid the hitting reliably.
