A trajectory planning system for a vehicle includes a sensor system for measuring an actual curvature on the basis of a respective current yaw rate, a memory containing a target trajectory with target curvatures, wherein the trajectory planning system determines target yaw rates from the target curvature, and a steering system that uses steering variables to obtain target curvatures in actual curvatures. The system determines a respective first actual derivative of the measured respective current actual yaw rate over time and a respective first target derivative of the respective current target yaw rate over time. A correlator determines a respective current delay on the basis of the respective first actual derivatives and the respective first target derivatives in a current yaw rate segment, and a parameter estimator recursively estimates the delay between the target yaw rate and the actual yaw rate on the basis of respective current delay inputs.

The MDPS includes an information detection unit configured to detect information about the behavior of a vehicle; and a controller configured to receive the information about the behavior of the vehicle from the information detection unit, to determine whether the vehicle is accelerating and whether the vehicle pulls to one side, and to generate compensation torque and drive a driving motor based thereon.

A vehicle has a wheel, a frame, a suspension component, a steering knuckle, and a steering system. The suspension component is connected to the frame. The steering knuckle is connected to the suspension component and is connected to the wheel. The suspension component is operable to control vertical movement of the steering knuckle and the wheel relative to the frame. The suspension component and the steering knuckle define a steering axis for the wheel. The steering axis has a caster inclination angle of zero degrees. The steering system is connected to the suspension component and controls a steering angle of the wheel based on an electronic control signal.

The apparatus includes a radius of curvature setting unit that sets a target radius of curvature of rotation of the vehicle while the vehicle is being driven and a radius of curvature calculation unit that estimates an actual radius of curvature of a traveling vehicle based on forward speed and lateral acceleration of the vehicle. Additionally, a radius of curvature adjustment unit adjusts a yaw direction rotation moment of the vehicle based on a difference between the target radius of curvature set by the radius of curvature setting unit and the estimated radius of curvature estimated by the radius of curvature calculation unit to adjust the radius of curvature of rotation of the vehicle.

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 vehicular behavior control apparatus in which a control unit that controls a driving device and a braking device is configured to calculate a target yaw moment and a target deceleration of the vehicle for ensuring stable behavior of the vehicle during non-braking turning, to calculate a first vehicle longitudinal force applied to a turning inner wheel to achieve the target yaw moment and a second vehicle longitudinal force necessary to achieve the target deceleration, to control, when the first vehicle longitudinal force is equal to or less than the second vehicle longitudinal force, the driving device so as to generate a driving force equal to a value obtained by subtracting the second vehicle longitudinal force from a driver-requested driving force and adding the first vehicle longitudinal force, and to apply the first vehicle longitudinal force to the turning inner wheel.

A control unit for a vehicle having an active steering system capable of changing a steering gear ratio between a steering angle of a steering wheel and a tire steering angle includes a steering turning assist controller and a left-right driving force controller. The steering turning assist controller controls the steering gear ratio so that a yaw rate generated by the vehicle becomes a target yaw rate to assist a turning of the vehicle. The left-right driving force controller controls, in the left and right electric drive wheels which each add a yaw moment to a vehicle body independently of a steering system and are able to be independently driven, driving forces of the electric drive wheels so that the yaw rate generated by the vehicle becomes the target yaw rate based on a roll of the vehicle.

A vehicle-trailer hitch angle sensor assembly includes a mounting bracket including a base, a body rotatably coupled with the bracket about an axis spaced apart from the base and biased toward the base, and a sensor array including a plurality of sensors extending in first and second directions along a face of the body.
