Vehicle seat adapted to protect occupant from injury in rear end collision

Abstract: Seat back rapidly deflates on occurrence of a rear end impact to permit upper torso of vehicle occupant to sink into the seat rather than be propelled forward. This permits his head to meet the headrest. Particulate material in headrest absorbs energy.

Rear-end collision warning device

Abstract: PROBLEM TO BE SOLVED: To provide a rear-end collision warning device matched with the driving feeling of the crew. SOLUTION: A rear-end collision warning device is provided with a laser radar 1 which detects distance between a vehicle and a preceding vehicle on the vehicle, with a vehicle speed sensor 2 which detects the speed of the vehicle and with an accelerometer 3. It is featured in such a way that a minimum deceleration which must be applied to the vehicle so as to prevent the vehicle from colliding with the preceding vehicle is computed on the basis of the distance, between the vehicle and the preceding vehicle, detected by the laser radar 1, on the basis of the speed, of the vehicle, detected by the vehicle speed sensor 2 and on the basis of the acceleration, of the vehicle, detected by the accelerometer 3 and that a warning is issued to the driver when the minimum deceleration which must be applied to the vehicle reaches a prescribed value.

Vehicle emergency brake rear-end collision prevention system and vehicle

Abstract: The invention discloses a vehicle emergency brake rear-end collision prevention system and a vehicle. The vehicle emergency brake rear-end collision prevention system comprises a brake sensor, a controller and a brake warning unit, the brake sensor is arranged on a brake unit of the vehicle, the brake sensor monitors whether the brake unit is in an emergency brake working state or not, the brake sensor is in signal connection with the controller so as to transmit a working state signal of the brake unit to the controller, the controller is in signal connection with the brake warning unit, and the brake warning unit is arranged on the rear portion of the vehicle, and when the brake unit is in the emergency braking working state, the controller controls the brake warning unit to act so as to remind people behind the vehicle. The system has the advantages that whether a driver slows down or emergently brakes can be accurately reflected in time, and then a rear vehicle driver is reminded to prevent rear-end collisions.

Model predictive adaptive cruise control for reducing rear-end collision risk with follower vehicles

Abstract: Methods of and systems for adaptive cruise control (ACC) of a vehicle include a controller for the vehicle that is configured to execute a computer-implemented model predictive control and a safe spacing policy that reduces collision risk between the vehicle and both a leading vehicle and a following vehicle. The methods include sensing a speed of a leader vehicle in front of the ego vehicle and a distance of the leader vehicle from the ego vehicle, sensing a speed of a follower vehicle behind the ego vehicle and a distance of the follower vehicle from the ego vehicle, and controlling the speed of the ego vehicle to avoid collision with the leader vehicle while reducing risk of the ego vehicle being hit by the follower vehicle.
