20200341476 · 2020-10-29 ·

A system for estimating a trajectory of a vehicle includes vehicle state sensors detecting a state of movement of the vehicle and environment sensors monitoring an environment of the vehicle. A free space module determines a free space corridor based on the detected state of movement of the vehicle and the monitored environment of the vehicle. A goal point determination module determines at least one goal point for the trajectory to be estimated based on the free space corridor. A trajectory planning module estimates a reference trajectory based on the at least one goal point and calculates a deviation between an actual trajectory and the reference trajectory of the vehicle. A trajectory control module minimizes the deviation between the actual trajectory and the reference trajectory of the vehicle and outputs optimal control parameters for the movement of the vehicle based on the minimized deviation.

A vehicle drive assist apparatus includes an own vehicle position estimator, a storage, a traveling lane estimator, a target steering angle setting unit, an own vehicle speed detector, and a lateral position deviation calculator. The own vehicle position estimator estimates an own vehicle position, by receiving a positioning signal from a positioning information transmitter. The traveling lane estimator estimates a traveling lane, by referring to road map information stored in the storage and based on the estimated own vehicle position. The lateral position deviation calculator sets a lateral position deviation being an offset amount in a lateral direction. The target steering angle setting unit sets a target steering angle based on the estimated traveling lane, adds the lateral position deviation to a feedback term of the target steering angle, and sets, based on an addition result, the target steering angle allowing an own vehicle to travel along the traveling lane.

The vehicle control method includes: executing control of recovering a travel trajectory of the subject vehicle to a target trajectory, as ordinary control, by giving a steering amount in a lateral direction with respect to a travel lane of the subject vehicle; using detection data of the sensor to determine whether or not another vehicle is traveling in an adjacent lane to the travel lane of the subject vehicle; and when determining that the other vehicle is traveling in the adjacent lane ahead of the subject vehicle, increasing a response of the steering amount to a higher response than that in the ordinary control, before the subject vehicle passes the other vehicle.

SYSTEM AND METHOD FOR TRAILER ALIGNMENT

A vehicle maneuvering apparatus comprises an imaging device configured to capture image data and a controller in communication with a vehicle maneuvering system. The controller is configured to identify a coupler position of a trailer in the image data and compare a coupler height of the coupler position with a hitch height of a hitch ball.

METHOD OF PROVIDING A SCENARIO-BASED OVERLAY TORQUE REQUEST SIGNAL IN A ROAD VEHICLE STEER TORQUE MANAGER

Disclosed is a method of providing a scenario-based overlay torque request signal in a steer torque manager (1) during driver-override of an auxiliary steering assistance system (2) function in a road vehicle (3) having an EPAS system (4).

VEHICLE CONTROL SYSTEM

A vehicle control system includes: a turning device that turns a wheel of a vehicle; a steering sensor that detects a driver's steering operation; and a control device configured to execute automated turning control that controls the turning device to automatically turn the wheel, independently of the driver's steering operation. A modification desire degree represents a degree to which the driver's steering operation modifies vehicle travel caused by the automated turning control. During execution of the automated turning control, the control device calculates the modification desire degree based on a result of detection by the steering sensor. When the modification desire degree exceeds a threshold, the control device executes system suppression processing without terminating the automated turning control. In the system suppression processing, the control device weakens the automated turning control as compared to a case where the modification desire degree is equal to or lower than the threshold.
