Abstract
A passenger protecting device for a vehicle has a vehicle direction control unit, a collision avoidance judging unit, and at least one of a torque allocation ratio control unit and a helm angle actuator. The torque allocation ratio control unit controls a torque allocation ratio of wheels of the vehicle. The helm angle actuator is connected with the wheels to control helm angles thereof. The vehicle direction control unit controls at least one of the torque allocation ratio control unit and the helm angle actuator, to rotate the vehicle to a predetermined direction in the case where the collision avoidance judging unit determines that the collision of the vehicle is avoidless, so that the injury to the passenger is restricted.
Claims14
A passenger protecting device for a vehicle, the passenger protecting device comprising:
- a torque allocation ratio control unit for controlling a torque allocation ratio between at least one right wheel and at least one left wheel of the vehicle;
- a collision avoidance judging unit for judging whether or not a collision of the vehicle is avoidable;
- and
- a vehicle direction control unit, wherein
- in the case where the collision avoidance judging unit determines that the collision of the vehicle is avoidless, the vehicle direction control unit controls the torque allocation ratio control unit to rotate the vehicle to a predetermined direction so that an injury to the passenger is restricted.
A passenger protecting device for a vehicle, the passenger protecting device comprising:
- a helm angle actuator which is connected with at least one right wheel and at least one left wheel of the vehicle to control helm angles of the wheels;
- a collision avoidance judging unit for judging whether or not a collision of the vehicle is avoidable;
- and
- a vehicle direction control unit, wherein
- in the case where the collision avoidance judging unit determines that the collision of the vehicle is avoidless, the vehicle direction control unit controls the helm angle actuator to rotate the vehicle to a predetermined direction so that an injury to the passenger is restricted.
A passenger protecting method for a vehicle, comprising:
- calculating a distance between the vehicle and an obstacle;
- detecting a velocity of the vehicle;
- determining whether or not a collision between the vehicle and the obstacle is avoidable based on the velocity of the vehicle and the distance between the vehicle and the obstacle;
- determining whether or not there are passengers on seats of the vehicle;
- and
- rotating the vehicle to a predetermined direction in the case where it is determined that the collision is avoidless, wherein
- the predetermined direction of the vehicle is set so that the seat where it is determined that there is no passenger is positioned at a collision side as compared with the seat where it is determined that there is a passenger.
