A control unit configured to control a reaction force actuator that applies steering guide torque to a steering wheel calculates a target steering angle for causing a vehicle to travel along a curve, calculates target steering guide torque based on a deviation between the target steering angle and an actual steering angle, modifies the target steering guide torque such that the target steering guide torque is larger as an index value indicating at least one of the number of times or an integrated time in which a difference between a magnitude of the actual steering angle and a magnitude of the target steering angle exceeds a reference value is larger, and controls the reaction force actuator such that the steering guide torque becomes the target steering guide torque.

A lane change support device includes a control unit configured to execute lane change control for enabling a vehicle to automatically change lanes from a lane in which the vehicle is traveling to an adjacent lane. The control unit counts a holding time for which an operation part that is operated to a predetermined operation position to start the lane change control is continuously held at the operation position, starts the lane change control when the counted holding time reaches a predetermined threshold time, and calculates a proficiency level of a driver of the vehicle for an operation of the lane change support device during execution of the lane change control and sets the threshold time to be used for a successive lane change control based on the proficiency level.

Directional vehicle steering cues are presented to a vehicle operator to suggest a particular steering direction (e.g., left vs. right) or to warn the operator of the directionality of an impending hazard. A directional vehicle steering cue may include one or more changes in steering angle that convey an associated directionality. A directional steering cue can include a first vibration pattern that includes a change in steering angle in a first direction to represent, for example, a suggested right turn, followed by a second vibration pattern that includes a change in steering angle in a second direction opposite to the first direction. The angular rate of change of the steering angle in the first direction may be larger than the angular rate of change of the steering angle in the second direction such that the first vibration pattern is more perceptible to a vehicle operator than the second vibration pattern.

In a steer-by-wire steering system for a vehicle, a control unit (16) controls an operation of a steering actuator to cause the steered angle of wheels to be in a prescribed relationship to a steering angle, and an operation of the reaction force actuator (15) including a pair of reaction force motors (14) to cause the reaction force to be a value (Tt) corresponding to a steered state of the wheels, wherein the control unit is provided with a failure detection unit (36) configured to detect failures of the reaction force motors, and upon detecting a failure of one of the reaction force motors, progressively reduce an output (Tta) of the other reaction motor to a prescribed limit value (TL).

A steering system for a vehicle includes a housing section, a rack section configured to penetrate the housing section, a case section mounted in the housing section, and a sensor section, mounted in the case section, configured to engage the rack section and sense an amount of movement of the rack section while being rotated.

A steering column system includes a steering column shaft. Also included is a steering input device coupled to the steering column shaft. Further included is an energy absorbing mechanism operatively engaged with at least one of the steering column shaft and the steering input device. Yet further included is a column adjustment assembly configured to translate the steering column shaft between a retracted position and a driving position. Also included is at least one signal indicating whether the steering column shaft is in the retracted position or the driving position, and when the steering column shaft is in the retracted position, directional control of a vehicle is automated and the energy absorbing mechanism is in a non-operational state, and when the steering column shaft is returned to the driving position as indicated by the at least one signal, the energy absorbing mechanism is in an operational state.

A trailer angle identification system includes an imaging device configured to capture an image. A controller is configured to receive steering angle data corresponding to a steering angle of a vehicle, receive vehicle speed data corresponding to a vehicle speed, and estimate an angle of the trailer relative to the vehicle by processing the image, the steering angle data, and the vehicle speed data in at least one neural network.

A vehicle control system includes a camera configured to capture image data depicting a field of view proximate the vehicle is disclosed. The vehicle control system further includes a plurality of light sources in connection with the vehicle and a controller. The controller is configured to activate a plurality of lights in an alternating pattern and capture light reflected from at least one object with the camera at a time and corresponding to the alternating pattern of the plurality of lights. In response to variations in the light impinging upon the at least one object from the alternating pattern, the controller is configured to identify a distance of the object.

Disclosed are an apparatus and method for displaying a rear image of a vehicle. The apparatus for displaying a rear image of a vehicle includes a rear camera configured to capture a rear image of the vehicle, a steering angle sensor configured to sense a steering angle of a steering wheel, a display unit, and an image processing unit configured to convert the rear image captured by the rear camera when the vehicle moves backward into an image in a direction where the vehicle is to move backward according to the steering angle of the steering wheel that is sensed by the steering angle sensor, and display the converted image in the direction where the vehicle is to move backward through the display unit.

An automatic steering control device includes a forward recognition device, a traveling state detector, a lateral positional deviation calculator, a steering angle controller. The lateral positional deviation calculator calculates a first lateral positional deviation that is the lateral positional deviation ahead of the vehicle by a first distance, and a second lateral positional deviation that is the lateral positional deviation ahead of the vehicle by a second distance larger than the first distance. The steering angle controller performs first control on the steering angle so that an absolute value of the first lateral positional deviation decreases, and second control on the steering angle based on the second lateral positional deviation so that a difference between a change amount of the steering angle in the first control and a change amount of an actual steered angle that is a steered angle of wheels of the vehicle decreases.
