Abstract
A vehicle speed V is read (step S1), V is compared with a first threshold Vth1 (step S2), and, when V is not less than Vth1, a warning torque is set smaller with increase in V (step S3). When V is less than Vth1, V is further compared with a second threshold Vth2 (step S4), and when V is less than Vth2, the warning torque is set approximately in proportion to the vehicle speed (step S5); when V is not less than Vth2 and is less than Vth1, the warning torque is set at a predetermined constant value (step S6).

4. A vehicle deviation preventing apparatus comprising:
-
deviation determining means for detecting a driving lane on which a host vehicle is driving, and for determining whether the host vehicle will deviate from the driving lane, based on a positional relation between the driving lane and the host vehicle; and warning means for applying to a steering wheel a torque for issuing a warning to a driver, with a determination of a deviation; the vehicle deviation preventing apparatus having a vehicle speed detecting means for detecting a vehicle speed, wherein the warning means sets the torque for issuing the warning to the driver, smaller when the detected vehicle speed is high than when the detected vehicle speed is low, and wherein the torque applied by the warning means is set based on a yaw motion property of the vehicle. - View Dependent Claims (2, 3, 5, 19)

7. A vehicle deviation preventing apparatus comprising:
-
deviation determining means for detecting a driving lane on which a host vehicle is driving, and for determining whether the host vehicle will deviate from the driving lane, based on a positional relation between the driving lane and the host vehicle; and warning means for applying to a steering wheel a torque for issuing a warning to a driver, with a determination of a deviation; the vehicle deviation preventing apparatus having a driving environment grasping means for grasping a road driving environment, wherein the warning means sets the torque for issuing the warning to the driver, based on the grasped road driving environment, and wherein the road driving environment grasped by the driving environment grasping means is information about a lane width. - View Dependent Claims (8, 17, 18)

9. A vehicle deviation preventing apparatus comprising:
-
deviation determining means for detecting a driving lane on which a host vehicle is driving, and for determining whether the host vehicle will deviate from the driving lane, based on a positional relation between the driving lane and the host vehicle; and warning means for applying to a steering wheel a torque for issuing a warning to a driver, with a determination of a deviation; the vehicle deviation preventing apparatus having driving environment grasping means for grasping a road driving environment, wherein the warning means sets the torque for issuing the warning to the driver, based on the grasped road driving environment, and wherein the road driving environment grasped by the driving environment grasping means is inclination information of a road surface in a direction intersecting a driving direction. - View Dependent Claims (10, 20)

11. A vehicle deviation preventing apparatus comprising:
-
deviation determining means for detecting a driving lane on which a host vehicle is driving, and for determining whether the host vehicle will deviate from the driving lane, based on a positional relation between the driving lane and the host vehicle; and warning means for applying to a steering wheel a torque for issuing a warning to a driver, with a determination of a deviation; the vehicle deviation preventing apparatus having obstacle grasping means for grasping obstacle information around the vehicle, wherein the warning means sets the torque for issuing the warning to the driver, based on the grasped obstacle information. - View Dependent Claims (12, 21)
