    摘要: A CCD camera or equivalent sensor is mounted on a vehicle and used to detect lane markings (usually the white or yellow painted lines) on a roadway. An electric motor coupled to a steering system is used to provide a torque input to the steering, which may either assist or oppose the steering torque from a driver. A steering controller is designed to assist the driver to maintain the vehicle lane position by holding the vehicle at a target point using a biasing torque. The controller resumes application of the biasing torque upon expiration of a predetermined period of delay time since a change from the absence of detection of lane marking to the presence of detection of lane marking after the presence of detection of lane marking that continues for a period of time less than a predetermined period of time has occurred a predetermined number of times within a predetermined period of monitoring time or the absence of detection of lane marking continues for a predetermined period of time.

    摘要: An apparatus for vehicle lane following in which a look ahead sensor including a CCD camera and an image processor detects a lane marking on the surface of a roadway. The image processor estimates a lateral displacement of a point at a preview distance in front of a vehicle from a target line. The target line is a line between lane markings defining a lane. An electric motor coupled to the steering mechanism is used to provide a bias (a torque input) to the steering, which may either assist or oppose to the steering torque from the driver. A steering controller is designed to assist the driver to maintain the vehicle's lane position by holding the vehicle at the target line using a biasing torque if the lane following is selected by the driver. In order to reflect the driver preference in the lane following, the controller collects a sufficient number of measures of the vehicle lateral displacement when the lane following is not selected. Based on the collected data, the controller updates the target line position. In the subsequent lane following, the driver is assisted to maintain the vehicle at this updated target line.

    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: A control type vibro-isolating support includes a pulse signal generator for generating reference signals x, which represent the state of the vibration being generated by an engine. An acceleration sensor detects residual vibration on the support member side, and generates a residual vibration signal e. A controller is supplied with the reference signals x and residual vibration signal e. On the basis of the reference signals x and residual vibration signal e and in accordance with, for example, synchronous filtered X LMS algorithm, the controller generates a drive signal y so as to lower the vibration level on the member side. An engine mount is interposed between the engine and the member, and has an electromagnetic actuator. The drive circuit for the actuator is supplied with the drive signal y. The controller judges that abnormality has occurred, if a maximum value of the residual vibration signal e exceeds a threshold, and if maximum values of the signal e have occurred at the same periodicity as the reference signals x.
