A drive assist apparatus, including a lane-keeping assist apparatus configured to apply an auxiliary steering torque to a steering mechanism mounted on a vehicle so that the vehicle runs at a predetermined position between lane lines, an operating member configured to be operated by an operator of the vehicle to output an activation signal for activating the lane-keeping assist apparatus, a determining unit configured to determine whether operation of the lane-keeping assist apparatus is necessary, and an outputting unit configured to output at least one of a notify signal for prompting the operator to operate the operating member and the activation signal, when the operating member is inoperative and it is determined that operation of the lane-keeping assist apparatus is necessary by the determining unit.

A lane keeping assist apparatus of a vehicle with a trailer, a system having the same, and a method thereof include a processor to request an advancing vehicle to control partial braking over the trailer of the advancing vehicle based on a lane departure amount of the advancing vehicle when the advancing vehicle departs from a lane.

A computer-implemented method includes: receiving, by a computing device, data identifying steering adjustments made by a driver; determining, by the computing device, an intent of the driver when making the steering adjustments; generating, by the computing device, steering assist instructions based on determining that the intent of the driver is to maintain the vehicle's position within a driving lane; and outputting, by the computing device, the steering assist instructions to counteract the steering adjustments made by the driver and maintain the vehicle's position within the driving lane.

A movable carrier auxiliary system includes at least one optical image capturing system disposed on a movable carrier, at least one warning module, and at least one displaying device. The optical image capturing system includes an image capturing module and an operation module, and has at least one lens group including at least two lenses having refractive power. The image capturing module captures and produces an environmental image surrounding the movable carrier. The operation module electrically connected to the image capturing module detects at least one lane marking in the environmental image to generate a detecting signal. The warning module electrically connected to the operation module receives the detecting signal to determine whether a moving direction of the movable carrier deviates from a lane, and generate a warning signal when the moving direction deviates from the lane. The displaying device electrically connected to the warning module displays the warning signal.

A lane deviation prevention control device for a vehicle includes an exterior information detector and a lane deviation prevention control start determiner. The lane deviation prevention control start determiner determines to start a lane deviation prevention control even when an own vehicle has already deviated from an own lane on which the own vehicle is traveling, on the condition that the exterior information detector detects an approaching vehicle that is approaching the own vehicle, on an adjacent lane on deviation side on which deviation is taking place, and that a lateral position of the own vehicle is equal to or smaller than a control start threshold.

A drive control method controls a drive control amount of a subject vehicle so that the subject vehicle may take a prescribed position with respect to lane markings of a lane in which the subject vehicle is running and reduces a drive control amount adopted when a lateral position of one of the lane markings along which the subject vehicle is running moves in a different direction from a lateral position of the other lane marking smaller than a drive control amount adopted when lateral positions of both the lane markings move in the same direction.

A computer in a vehicle is programmed to instruct a steering system of the vehicle to perform a lateral steering action depending on whether a steering-wheel angle is greater than a threshold angle, and to determine and apply an amount of torque to a steering wheel based on comparing the steering-wheel angle to the threshold angle.

A vehicle control processor and method capable of preventing departure to an off-road, to reduce driver discomfort, irritation and stress. The control processor calculates a width of a side strip between a left mark line and a road end based on information from a camera. When the width is wider than a specified width, steering torque based on first and second steering characteristics are exerted. The steering torque based on the first steering characteristic is exerted when a vehicle lateral end is located within a range from a left mark line outer end to a characteristic switching position, set in accordance with the width of the side strip between the left mark line and the road end, and the steering torque based on the second steering characteristic is exerted when the vehicle lateral end is located within a range from the characteristic switching position to the road end.

A drive control method controls a drive control amount of a subject vehicle so that the subject vehicle may take a prescribed position with respect to lane markings of a lane in which the subject vehicle is running and reduces a drive control amount adopted when a lateral position of one of the lane markings along which the subject vehicle is running moves in a different direction from a lateral position of the other lane marking smaller than a drive control amount adopted when lateral positions of both the lane markings move in the same direction.

A computer-implemented method includes: receiving, by a computing device, data identifying steering adjustments made by a driver; determining, by the computing device, an intent of the driver when making the steering adjustments; generating, by the computing device, steering assist instructions based on determining that the intent of the driver is to maintain the vehicle's position within a driving lane; and outputting, by the computing device, the steering assist instructions to counteract the steering adjustments made by the driver and maintain the vehicle's position within the driving lane.
