A lane-keeping system suitable for use on an automated vehicle includes a camera, an inertial-measurement-unit, and a controller. The camera is configured to detect a lane-marking of a roadway traveled by a vehicle. The inertial-measurement-unit is configured to determine relative-motion of the vehicle. The controller in communication with the camera and the inertial-measurement-unit. When the lane-marking is detected the controller is configured to steer the vehicle towards a centerline of the roadway based on a last-position, and determine an offset-vector indicative of motion of the vehicle relative to the centerline of the roadway. When the lane-marking is not detected the controller is configured to: determine an offset-position relative to the last-position based on information from the inertial-measurement-unit, determine a correction-vector used to steer the vehicle from the offset-position towards the centerline of the roadway based on the last-position and the offset-vector, and steer the vehicle according to the correction-vector.

A lane departure avoidance system disables start of steering control or terminate running steering control upon determination that a value of a at least one selected variation, which is selected from a first variation, a second variation, a third variation, and a fourth variation, is equal to or more than a corresponding threshold. The first variation is a variation of a lateral position of an own vehicle relative to lane marking lines recognized by a recognition unit, and the second variation is a variation of a yaw angle of the own vehicle relative to the recognized lane marking lines. The third variation is a variation of a curvature of the recognized lane marking lines, and the fourth variation is a variation of a pitch angle of the own vehicle.

The present invention extends to methods, systems, and computer program products for distinguishing roadway surface lane markings for a vehicle to follow. Automated driving or driving assist vehicles utilize sensors to help the vehicle navigate on roadways or in parking areas. The sensors can utilize, for example, the painted surface markings to help guide the vehicle on its path. When ambiguity is detected between roadway surface markings, decision making algorithms identify a set of roadway surface markings for a vehicle to abide by. The sensors can also identify the location and trajectory of neighboring vehicles to increase confidence with respect to an identified set of roadway surface markings.

Automated driving or driving assist vehicles utilize sensors to help the vehicle navigate on roadways or in parking areas. The sensors can utilize, for example, the painted surface markings to help guide the vehicle on its path. Aspects of the invention use a first type of sensor and at least a second different type of sensor to identify road surface markings. When ambiguity is detected between road surface markings, decision making algorithms identify the correct set of markings for a vehicle to abide by. The sensors also identify the location and trajectory of neighboring vehicles to increase confidence with respect to the identified road-surface markings.

A method for providing a warning to a vehicle driver when a lane keeping and/or lane centering system will be unable to negotiate a tight curve at the present vehicle speed prior to the vehicle reaching the curve. The method obtains lane information at a predetermined number of sample times in the future and generates a desired path for the vehicle. The method also obtains vehicle motion information and determines steering angles for the vehicle for the vehicle to track the desired path based on the desired path and vehicle motion. The method determines the steering torque for each of the steering angles and determines whether any of the steering torques exceed the predetermine torque limit. The method issues an alert if any of the steering torques do exceed the predetermined torque limit prior to the lane keeping system being required to provide that torque to steer the vehicle.

A vehicle travel control device for an automatic drive vehicle that does not require visual notification to other vehicles and that causes no sense of discomfort in any passengers on a host vehicle or other vehicles around the host vehicle with respect to a preliminary operation of the host vehicle is provided. In accordance with a determination as to whether the other vehicle is automatically driving, a preliminary operation control unit determines the need for an adjustment in the preliminary operation control amount. If the adjustment is not required, the preliminary operation control unit maintains the preliminary operation control amount as a final preliminary operation control amount. If required, the preliminary operation control unit adjusts the preliminary operation control amount to obtain a final preliminary operation control amount for the execution of the preliminary operation of the devices.

An inspection device for vehicle driver assistance systems (DASs) mounted on a vehicle may include: i) a frame unit including pillar frames, where vehicles forwardly enter and backwardly exit, at respective corners of a base frame, and an upper frame is coupled to upper end portions of the pillar frames; a correction unit installed at the upper frame such that it is movable in multi-axis directions so as to correct a camera measurement point of a lane departure warning system (LDWS) at a front side of the vehicle and configured to display a correction target with respect to the camera as an image; and an inspection unit installed at the upper frame such that it is movable in multi-axis directions so as to check a normal operation of the LDWS and configured to display a driving lane as an image.

A method for controlling the lateral position of a vehicle on a traffic lane includes: a first controlling of the vehicle following a first reference trajectory, alerting the driver if the lateral distance separating the vehicle from the edge of the traffic lane is less than a first threshold, then detecting a command applied to a steering wheel of the vehicle, then a second controlling of the vehicle following a second reference trajectory, the second trajectory being determined depending on the command applied to the steering wheel, and alerting the driver if the lateral distance separating the vehicle from the edge of the traffic lane is less than a second threshold, the second threshold being less than the first threshold.

A vehicle is capable of performing automated driving including a lane keep control, which is to automatically perform lane keep of a vehicle, and an offset control, which is to automatically offset a travel position of the vehicle in a width direction of the vehicle by increasing a distance from an other vehicle, which travels side-by-side with the vehicle. A control device for the vehicle includes a lane change control unit and an adjusting unit. The lane change control unit is configured to automatically perform lane change. The adjusting unit is configured to, when the lane change control unit performs the lane change during the lane keep control and the offset control, finish the offset control and move the vehicle to a center of a travel lane of the vehicle, and subsequently cause the lane change control unit to perform the lane change.
