摘要： A lane departure prevention apparatus is configured to conduct a course correction in a lane departure avoidance direction when the controller 8 determines that there is a potential for a vehicle to depart from a driving lane. The controller 8 combines yaw control and deceleration control to conduct departure prevention control to avoid lane departure. The yaw control is not actuated if the opposite direction from the steering direction coincides with the lane departure direction (steps S10 and S11). Preferably, the controller 8 sets the timing of yaw moment and the deceleration of the vehicle on the basis of the acceleration or deceleration of the vehicle, and performs braking control so that these settings are achieved (steps S7 to S9). Preferably, the controller 8 calculates the target yaw moment in the lane departure-avoidance direction on the basis of the running state of the vehicle, and calculates the deceleration amount by taking into account the driver braking operation amount.

摘要： A method for lane-keeping control of a lane-keeping support system provides a current command indicative of steering torque assist needed to steer a vehicle in following a target line between lane markings on a roadway during driving in lane-keeping control (LKC) mode. A map has two sets of limit data against a range of values of lateral acceleration to which the vehicle is subject, between which sets of limit data there is a range of values of the command during various phases of steering the vehicle to turn in the LKC mode. In order to compensate for undesired effect caused by any deviation of the range of values of the current command due to the presence of continuous disturbance, the two sets of limit data are corrected. To determine driver steering intervention, the instantaneous value of the current command is compared to two limit values established out of the corrected two sets of limit data.

摘要： A lane-keep control system for a host-vehicle is arranged to execute a lane-keep control for moving the host-vehicle in a traveling lane, to determine whether there is an approaching-vehicle behind the host-vehicle, to increase an intervention threshold when there is the approaching vehicle behind the host-vehicle, and to suspend the lane-keep control when a steering control indicative value due to driver intervention is greater than the intervention threshold.

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 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 dependence on whether the control steering direction is a steer direction away from a straight ahead neutral position or a return direction toward the straight ahead neutral position, to take account of a self aligning torque.
