Patent Images
1. A warning system with vibration for an automotive vehicle comprising:
- a sensing section detecting operational states of the vehicle;
a wheel actuator variably adjusting road wheel speed of a road wheel; and
a control unit configured to be connected electrically to the sensing section and the wheel actuator, for automatically controlling fluctuations in the road wheel speed to generate vibrations in the vehicle based on the operational states of the vehicle.

Abstract
A warning system for an automotive vehicle produces a vibration in the vehicle simulating a rumble strip to inform a driver of various events. A vibration with braking torque is produced by controlling individually brake fluid pressure in each wheel brake cylinder, independently of manual braking operations. The warning system is applied to a lane deviation prevention (LDP) system. The LDP system provides a warning with vibration and a control effort of yawing moment by wheel torque or steering torque.

30. A method of warning with vibration for an automotive vehicle comprising:
-
detecting operational states of the vehicle; determining a degree of lane deviation of the vehicle from a current driving lane based on the operational states of the vehicle; determining whether there is a possibility of lane deviation of the vehicle based on the degree of lane deviation; and producing fluctuations in a road wheel speed to generating vibrations in the vehicle when it is determined that there is a possibility of lane deviation of the vehicle.
