    摘要： A system for assisting a lane-keep traveling of a vehicle is comprised of a camera for detecting a view ahead of the vehicle, a vehicle behavior detector including a vehicle speed sensor and a yaw rate sensor, and a controller. The controller is arranged to estimate a road shape on the basis of lane markers detected by the camera, to detect a target yaw rate necessary to return the vehicle at a center of the lane markers, and to determine that there is a possibility that the vehicle deviates from the lane when a difference between the target yaw rate and an actual yaw rate detected by the yaw rate sensor becomes greater than a threshold.

    摘要： In accordance with a vehicle running condition along a lane and an actual steering angle, a control unit determine a target steering angle to follow the lane, and controls an actual steering torque with an actuator to a target steering torque to achieve the target steering angle. The control unit limits the target steering torque by setting a target torque limit determined in accordance with a sensed longitudinal acceleration of the vehicle.

    摘要： A lane deviation alarm system is comprised of a forward-observed-point calculating section that calculates a forward observed point by multiplying a vehicle speed of a host vehicle and an anticipated deviation time; a forward-observed-point lateral-displacement calculating section that calculates a lateral displacement at the forward-observed-point, on the basis of a yaw angle and the forward-observed-point; a lane deviation tendency determining section that determines whether the host vehicle is in a lane deviation tendency, on the basis of the forward-observed-point lateral-displacement; and a criteria changing section that changes a criteria for determining a lane deviation tendency of the host vehicle, on the basis of a detecting condition of the lane defining line.

    摘要： A driver assistance system (10) assists the driver in controlling the direction of a moving vehicle along a contrived centerline between lane markings by regulating a steering bias applied to a steering system of the vehicle. An electric motor (22) coupled to the steering mechanism provides a torque input to the steering in response to an estimate of electric current provided by an observer. The observer has a friction term matrix element (a55), which is correlated with friction in the steering mechanism. A controller (24) is provided, which establishes a desired or ideal frequency function of lateral displacement data (102), samples lateral displacement to provide a real frequency function of lateral displacement data (104), compares the real frequency function with the ideal frequency function (106), and updates or leaves unaltered the friction term (a55) based on the result of comparison.

    摘要： In an automotive lane deviation prevention (LDP) apparatus capable of executing LDP control by which a host vehicle is avoided from deviating from a driving lane, a control unit includes an LDP control allotted amount calculation section that calculates, responsively to a host vehicle's turning state, a steering-control allotted amount for LDP control and a braking-force-control allotted amount for LDP control, in presence of the host vehicle's lane-deviation tendency from the driving lane. In order to avoid the host vehicle's lane-deviation tendency, steering torque is controlled responsively to a steering-torque-control controlled variable determined based on the steering-control allotted amount, whereas braking forces applied to respective road wheels are controlled responsively to braking-force-control controlled variables determined based on the braking-force-control allotted amount.
