    Abstract: In lane keeping assistance system and method for an automotive vehicle, a control current (Iout) to be outputted to a motor during an automatic steering mode is detected, a filter is provided for the detected control current to pass only signal components of the detected control current whose frequencies are lower than a predetermined cut-off frequency value (fstr, fstr_low, fstr_mid, fstr_hi) to derive a filtered control current (Iout_lpf), a determination of whether a manual steering intervention to the automatic steering occurs is made according to a magnitude of the filtered control current, and the control current outputted to the motor is reduced toward zero when the manual steering intervention is determined to occur according to a result of determination that the magnitude of the filtered control current (Iout_lpf) is in excess of a predetermined threshold current value (Iout_lpf_th).

    Abstract: A lane tracking control system for a vehicle includes a controller which is coupled to a road image detector for taking a view ahead of the vehicle, a vehicle behavior detector for detecting a behavior of the vehicle and a steering control mechanism for executing a steering control in response to a steering control signal. The controller is arrange to calculate a road shape on the basis of the view taken by the road image detector, to determine on the basis of the road shape and the vehicle behavior detected by the vehicle behavior detector whether the vehicle tends to depart from a lane traveled by the vehicle, and to output the steering control signal to the steering control mechanism so as to control the vehicle behavior at a desired behavior when the vehicle tends to depart from the lane.

    Abstract: Preview information is obtained by processing data from image data of a CCD camera, and it is treated as a known disturbance. Then, models for a vehicle and a target road path, typically consisting of DARMA (deterministic auto-regressive moving average) models are prepared so as to give a relationship between a front wheel steering angle command and a lateral deviation of the vehicle. An extended generalized predictive control theory is applied to these models so as to compensate for tracking errors that may arise as a result of the known disturbance. Thus, a favorable tracking capability can be achieved with a relatively simple structure, by executing a prediction control which requires only such variable that can be measured both easily and accurately.

    Abstract: A system and method assist the driver of a motor vehicle in preventing accidents or minimizing the effects of same. In one form, a television camera is mounted on a vehicle and scans the roadway ahead of the vehicle as the vehicle travels. Continuously generated video picture signals output by the camera are electronically processed and analyzed by an image analyzing computer, which generates codes, that serve to identify obstacles. A decision computer mounted in the controlled vehicle receives such code signals along with code signals generated by the speedometer or one or more sensors sensing steering mechanism operation and generates control signals. Such code signals maybe displayed, and as synthetic speech or special sound generating and warning means used to warn the driver of the vehicle of approaching and existing hazards. The system may also use the control signals, particularly through application of fuzzy logic, to control the operation of the brakes and steering mechanism of the vehicle to avoid or lessen the effects of a collision. In a particular form, the decision computer may select the evasive action taken from a number of choices, depending on whether and where the detection device senses other vehicles or obstacles.

    Abstract: A device for keeping a vehicle in its lane, including a reference model, which obtains geometric data regarding the position of the vehicle in the lane as well as data relating to the course of the lane from a lane detection system, and from these calculates a setpoint variable for controlling the vehicle position. In order to allow for corners to be cut, the guiding behavior of the control system is modified in such a way when cornering that, in the event of a deviation of the path of motion of the vehicle from the setpoint path of motion in the direction of the inside of the curve, no or only low steering forces are applied to the steering system.
