Abstract: A braking control system (1) includes: an ECU (20) that determines the likelihood of collision with an object based on detection results by a millimeter wave radar (10), a stereo camera (11) and the like; a brake actuator (30) that automatically applies a braking force based on the determination results; a steering angle sensor (14) that detects the steering condition by a driver; and so forth.
