Title:
BRAKE CONTROL DEVICE
Document Type and Number:
Japanese Patent JPH10297452
Kind Code:
A
Abstract:

To provide a brake control device that is able to suitably brake a vehicle when finding an obstacle in the traveling direction.

A distance with an obstacle detected by a laser radar is read in (S110). A fact of whether this distance SL with the obstacle is entered within the range of a distance kSL to do control for increasing an extent of braking force or not is judged (S120). Likewise, whether a brake pedal is operated or not is judged (S130). Servo assisting action of a brake booster is heightened according to the distance of up to the obstacle, and thereby such a process as increasing the braking force is carried out (S140). Concretely, a compressor is turned on into operation, while each duty ratio control of both first and second solenoid valves is carried out. In addition, whether a vehicle is stopped or not is judged on the basis of a signal out of a wheel speed sensor (S150).
