Abstract:
PURPOSE: A device for absorbing shock energy generated in braking is provided to reduce vibration of a vehicle body, to decrease breakdown of parts of a brake system, and to reduce fatigue of drivers by removing shock energy flowing backward to a master cylinder with a damper. CONSTITUTION: A device for absorbing shock energy generated in braking has a damper(10) mounted at each brake hose(3) for connecting a master cylinder(2) and a vehicle wheel(4) to remove shock energy when fluid contained in the brake hose is changed into shock energy by various vibration generated from a brake body(5) in braking and inserted backward into the master cylinder. When a piston member of the damper is ascended and an energy absorbing member is compressed to absorb the shock energy, the shock energy of 150 bar is disappeared.

The drive support ECU 94 includes a collision possibility determining unit for determining a possibility of collision of a driver's own vehicle and a collision determining unit for detecting collision of the driver's own vehicle. The brake ECU 1 includes an abnormality detecting unit for detecting abnormality of the fluid pressure channel at the time the brake fluid pressure of the fluid pressure channel has become equal to or smaller than a threshold value and a brake controller for reducing a pressurizing amount of the brake fluid pressure supplied to the fluid pressure channel or reducing the pressurizing amount to 0 before the collision of the driver's own vehicle in a state that the possibility of collision of the driver's own vehicle has been detected or after the collision, when the pressurizer 70 has pressurized the brake fluid by the detection of the possibility of the collision and the pressurized brake fluid pressure has been supplied to the fluid pressure channel.

Abstract:
When providing adaptive cruise control (ACC) in addition to collision mitigation (CM) for a large vehicle, foundation braking is prohibited for maintaining a set following time behind a forward vehicle in order to mitigate unnecessary brake activations. When collision mitigation is activated, the collision mitigation system is given priority over other vehicle control systems with regard to the foundation brakes, in order to avoid a collision. A lateral acceleration module monitors lateral acceleration of the host vehicle during collision mitigation foundation brake application, and if lateral acceleration exceeds a predetermined threshold, foundation brakes are prohibited in order to prevent vehicle rollover.
