Abstract:
1. An emergency brake system for a vehicle comprising: a first brake for braking the rotation of a wheel; a second brake for braking the vehicle by increasing frictional resistance with a road surface; an obstacle detector for detecting an obstacle existing in an advancing direction of the vehicle; a vehicle speed and deceleration detector for detecting the speed and deceleration of the vehicle; a hard braking detector for detecting the actuation of hard braking by said first brake or actuation requirements for hard braking by a driver; and a controller for determining whether or not the vehicle is going to crash into the obstacle detected by said obstacle detector based on the speed and deceleration detected by said vehicle speed and deceleration detector, after the actuation of hard braking or the actuation requirements have been detected by said hard braking detector; wherein said second brake is actuated if said controller determines that the vehicle is going to crash into the obstacle detected by said obstacle detector.
