Abstract
A rollover protecting system for a vehicle comprising an actuator for pushing out an upper arm to an external direction of the vehicle by pivoting a pivot arm such that a tire produces a positive camber in relation to the road surface. Protruding ends are formed on a shoulder part of the tire for reducing a contact surface of the tire to the road, thereby reducing the lateral force applied to the tire and preventing an occurrence of rollover.
Claims3
A rollover protecting system for a vehicle, comprising:
- a plurality of sensors sensing a state of a vehicle;
- an electronic control unit (ECU) calculating a roll angle of a vehicle by using values inputted from said plurality of sensors;
- an actuator activated by said ECU and adjusting a tire to a positive camber when said ECU detects an occurrence of a rollover;
- and
- protruding ends formed on a shoulder part of the tire for contacting a road surface and reducing a lateral force on the tire when the tire is adjusted to the positive camber, wherein each of said protruding ends comprises a ring shape around said shoulder part, and said protruding ends are aligned in plural rows at a constant interval and slopingly protrude out from said shoulder part toward the road surface.
