Abstract:
In a vehicle dynamics control apparatus capable of balancing a vehicle dynamics stability control system and a lane deviation prevention control system, a cooperative control section is provided to make a cooperative control between lane deviation prevention control (LDP) and vehicle dynamics stability control (VDC). When a direction of yawing motion created by LDP control is opposite to a direction of yawing motion created by VDC control, the cooperative control section puts a higher priority on VDC control rather than LDP control. Conversely when the direction of yawing motion created by LDP control is identical to the direction of yawing motion created by VDC control, a higher one of the LDP desired yaw moment and the VDC desired yaw moment is selected as a final desired yaw moment, to prevent over-control, while keeping the effects obtained by both of VDC control and LDP control.
Abstract:
A lane departure prevention system comprises a traveling status detecting unit for detecting current lateral displacement and current yaw angle of a vehicle relative to a lane of travel, a departure detecting unit for detecting whether the vehicle is tending to depart from the lane of travel on the basis of current lateral displacement of the vehicle relative to the lane of travel as detected by the traveling status detecting unit; and a departure avoidance control unit for controlling the vehicle to avoid lane departure when the departure detecting unit detects that the vehicle is tending to depart from the lane of travel. The departure avoidance control unit calculating the extent of control necessary to avoid lane departure on the basis of current yaw angle of the vehicle detected by the traveling status detecting unit. Provision is made for preventing lane departure on a curving as well as a straight road.
Abstract:
A method and a system for automatically detecting unintended lane departures of vehicles are described. A lane departure warning system comprises a lane departure recognition unit (10), an alarm generation unit (12), and a driver activity monititoring unit (14). The driver activity monitoring unit (14) is configured to monitor one or more vehicle-related parameters like the steer angle that change continuously in response to a control intervention of a driver. The alarm generation unit (12) generates an alarm if an actual or forthcoming lane departure is detected and if additionally an evaluation of the one or more parameters indicates a low or no driver activity.

Abstract:
A system for steering a vehicle including: an actuator disposed in a vehicle to apply torque to a steerable wheel; a driver input device receptive to driver commands for directing the vehicle; and a sensor for determining an intent of a driver and generating a signal indicative thereof. The system also includes: a lane keeping system for detecting a location of the vehicle relative to a lane marker and generating a lane position signal indicative thereof; a controller in operable communication with the actuator, the driver input device, the first sensor, and the lane keeping system. The controller provides a command to the actuator responsive to the intent of the driver, the lane position, and a desired lane position. The controller executes a lane keeping algorithm consisting of a single control loop based on at least one of the lane position and the lane position deviation.
Abstract:
An intention estimation and operation assistance system for estimating an operator's intention and providing assistance to operation of a machine. Reference data, such as the operation of a plurality of hypothetical operators, is provided for comparison with the operation of a real operator, to determine an estimated intention of the operator. The estimated operator is utilized to alter the operation of the machine, to provide a safer and/or smoother operation experience in operating the machine.
Abstract:
In deviation prevention support ECU 10 in driving operation support system 1, an applied torque by steering torque applier 17 is set based on a vehicle speed of a vehicle. The applied torque is set to increase with increase of the vehicle speed. An upper limit according to the vehicle speed is set for this applied torque. Furthermore, in a Start interval in application of the applied torque, a rate of increasing to reach a maximum is determined according to the maximum of the applied torque. In a close interval, the applied torque is decreased at a rate different from that in the Start interval, and the absolute rate of increasing the torque in the Start interval is set to be larger than the absolute rate of decreasing the torque in the close interval.
Abstract:
A driving lane recognition system which can improve the lane recognition accuracy by stably detecting the various kinds of lane markers is disclosed. An image processing means 6 for image-processing a road image taken by a camera 5 has a plurality of different kinds of image processing algorithms 9 to 11. A driving lane is detected by selecting an image processing algorithm suitable for the driving lane out of the plurality of different kinds of image processing algorithms 9 to 11 corresponding to a road on which a vehicle is running.
Abstract:
The present invention relates to a method and a device for the lateral guidance of a vehicle. A warning device that outputs a warning signal when straying from a traffic lane is able to be turned off by a switching means when driving on a road that is not suitable for lateral guidance, in particular an inner-city road, and be turned on again when reaching a road that is suitable for lateral guidance.
Abstract:
A lane departure prevention apparatus is provided to improve safety while preventing lane departure. The lane departure prevention apparatus determines whether or not the driver is holding the steering wheel steady, determines whether or not the host vehicle has a tendency to depart from its driving lane, and, on the basis of these determination results, outputs a warning and performs braking control for avoiding the lane departure of the host vehicle when the host vehicle has a tendency to depart from its driving lane, and the driver is not holding the steering wheel steady.
