Automotive lane deviation prevention apparatus
First Claim
1. An automotive lane deviation prevention apparatus comprising:
- a processor programmed to perform the following, executing vehicle yawing motion control by which a host vehicle returns to a central position of a driving lane, when the host vehicle is traveling on predetermined irregularities formed on or close to either one of a left-hand side lane marking line and a right-hand side lane marking line of the driving lane.

Abstract
An automotive lane deviation prevention apparatus includes an electronic control unit configured to be electronically connected to a yawing-motion control actuator such as braking force actuators or a steering actuator for lane deviation prevention and vehicle yawing motion control purposes. The control unit has a processor programmed for determining whether or not a host vehicle is traveling on predetermined irregularities formed on or close to either one of a left-hand side lane marking line and a right-hand side lane marking line of a driving lane. The processor is further programmed for executing vehicle yawing motion control by which the host vehicle returns to a central position of the driving lane, when the host vehicle is traveling on the predetermined irregularities.

16. An automotive lane deviation prevention apparatus comprising:
-
sensors that detect whether a host vehicle is traveling on predetermined irregularities formed on or close to either one of a left-hand side lane marking line and a right-hand side lane marking line of a driving lane;
a yawing-motion control actuator that adjusts a yaw moment exerted on the host vehicle;
a control unit being configured to be electronically connected to the yawing-motion control actuator and the sensors, for controlling the yawing motion of the host vehicle in response to signals from the sensors for yawing motion control purposes;
the control unit comprising(a) road-surface irregularities detection means for determining, based on the signals from the sensors, whether the host vehicle is traveling on the predetermined irregularities; and
(b) vehicle yawing motion control means for executing vehicle yawing motion control by which the host vehicle returns to a central position of the driving lane, when the road-surface irregularities detection means determines that the host vehicle is traveling on the predetermined irregularities.

17. A method of preventing lane deviation of a host vehicle employing braking force actuators that adjust braking forces applied to respective road wheels, the method comprising:
-
detecting whether the host vehicle is traveling on predetermined irregularities formed on or close to either one of a left-hand side lane marking line and a right-hand side lane marking line of a driving lane; and
executing lane deviation prevention control by feedback-controlling the braking forces applied to the road wheels so that the host vehicle returns to a central position of the driving lane, when the host vehicle is traveling on the predetermined irregularities.

-
18. A method of preventing lane deviation of a host vehicle employing a steering actuator that adjusts a steering torque applied to a steering wheel, the method comprising:
-
detecting whether the host vehicle is traveling on predetermined irregularities formed on or close to either one of a left-hand side lane marking line and a right-hand side lane marking line of a driving lane; and
executing lane deviation prevention control by feedback-controlling the steering torque applied to the steering wheel so that the host vehicle returns to a central position of the driving lane, when the host vehicle is traveling on the predetermined irregularities.
