Abstract
A system for preventing lane deviation of a vehicle is provided. The system comprises a lane detecting device, a running condition detecting device, a deviation judging device, and a vehicle behavior control device. The vehicle behavior control device controls a behavior of the vehicle so as to generate a yaw moment in the direction to prevent the vehicle from deviating from the running lane. The lane detecting device detects the running lane based on a variation in a running direction of the vehicle due to the yaw moment generated by the vehicle behavior control device. A method for preventing lane deviation of a vehicle is also provided.
Claims12
A system for preventing lane deviation of a vehicle comprising:
- a lane detecting device that detects a running lane of the vehicle;
- a running condition detecting device that detects a running condition of the vehicle;
- a deviation judging device that judges based on the detected running lane and the detected running condition of the vehicle whether the vehicle has a tendency to deviate from the running lane;
- and
- a vehicle behavior control device that controls a behavior of the vehicle so as to generate a yaw moment in the direction to prevent the vehicle from deviating from the running lane in accordance with the detected running condition when the deviation judging device judges that the vehicle has a tendency to deviate from the running lane;
- wherein the lane detecting device detects the running lane of the vehicle based on a variation in a running direction of the vehicle due to the yaw moment generated by the vehicle behavior control device.
A system for preventing lane deviation of a vehicle comprising:
- lane detecting means for detecting a running lane of the vehicle;
- running condition detecting means for detecting a running condition of the vehicle;
- deviation judging means for judging based on the detected running lane and the detected running condition whether the vehicle has a tendency to deviate from the running lane;
- and
- vehicle behavior control means for controlling a behavior of the vehicle in a way as to generate a yaw moment in the direction to prevent the vehicle from deviating from the running lane in accordance with the detected running condition when the deviation judging means judges that the vehicle has a tendency to deviate from the running lane;
- wherein the lane detecting means detects the running lane based on a variation in a running direction of the vehicle due to the yaw moment that is generated by the vehicle behavior control means.
A method for preventing lane deviation of a vehicle comprising:
- detecting a running lane of the vehicle;
- detecting a running condition of the vehicle;
- judging based on the detected running lane and the detected running condition whether the vehicle has a tendency to deviate from the running lane;
- and
- controlling a behavior of the vehicle so as to generate a yaw moment in the direction to prevent the vehicle from deviating from the running lane in accordance with the detected running condition when the vehicle is judged to have a tendency to deviate from the running lane;
- wherein the detecting of the running lane comprises detecting the running lane based on a variation in a running direction of the vehicle due to the yaw moment generated by the controlling of the behavior of the vehicle.
