A steering control system for a vehicle that considers the limitations of at least one of the vehicle and the environment is contemplated. The steering control system can receive a vehicle characteristic, an environmental condition, a desired amount of turning, and a desired velocity of the vehicle. Based on some, or all of these parameters, the steering control system can determine at least one of a wheel torque, a wheel angle, a wheel camber, and a wheel suspension for a desired vehicle path to enhance vehicle performance.

An autonomous vehicle (AV) is automatically navigated within a a driving lane. Lane line data is received from one or more sensors, such as one or more cameras. A first parametric curve can be matched to a location of a first lane line detected from the lane line data. A second parametric curve can be matched to a location of a second lane line detected from the lane line data. A center parametric curve can be then generated in the center of the first parametric curve and the second parametric curve. The center parametric curve is then sampled to generate a discrete vector of trajectory points along the center parametric curve. The AV is then navigated along the road based on the trajectory points.

Self-propelled vehicles that include swiveling caster wheels and independent drive wheels are disclosed. The self-propelled vehicles are selectively steered in a caster wheel steering mode or a drive wheel steering mode. The vehicle includes a steering position sensor to measure the position of the steering system. A control unit varies the rotational speed of first and second drive wheels based at least in part of the signal from the steering position sensor.

An example, described herein, involves monitoring an operating input of a vehicle; determining a turning maneuver is to be performed by the vehicle with a decreased turn radius based on the operating input; determining that a transmission of the vehicle is to be downshifted to a low gear to enable the vehicle to perform the turning maneuver; and downshifting the transmission to the low gear.

The present invention provides a vehicle control device and method capable of ensuring steering accuracy. In a vehicle provided with a left-right pair of steered wheels for which the braking/driving forces can each be controlled, and a steering force generation device that generates steering force for the steered wheels and controls the steering angle of the steered wheels, this vehicle control device and method control the steering force and the steering reaction force from the steering force generation device by controlling the braking/driving force of each of the steered wheels on the basis of the lateral force acting on the steered wheels.

A method for terminating driving on the road shoulder by a transportation vehicle includes detection by a detection unit that the transportation vehicle is situated at least partially on a road shoulder, determination of a steering intensity of a manual steering maneuver, and assignment of one of at least two predetermined steering codes to the steering maneuver by a computing unit as a function of the steering intensity. An automatic intervention into a transportation vehicle control is carried out as a function of the assigned steering code.

A small radius- or zero radius-turn vehicle that may be steered by differentially-driven rear drive wheels and by at least one electronically-controlled, steerable front wheel. A device, e.g., one or more levers, may be provided that controls both speed and direction of the drive wheels. A sensor may be provided that detects a position of the lever(s). A controller may calculate a steering angle of the front wheel based upon the position, and issue a command to an actuator associated with the front wheel. The actuator may rotate the front wheel to an electronically calculated steering angle in response to the command.

Systems and methods for planning and executing a sequence of lateral controls for a vehicle comprise determining a set of parameters comprising road lane lines, a pose of the vehicle, a movement state of the vehicle, and actions by a driver of the vehicle and, while operating the vehicle in an autonomous driving mode, obtaining a long-term recurrent convolutional network (LRCN) model that has been trained with training data captured during controlled test driving by a human driver, using the LRCN model and the set of parameters as inputs, determining a sequence of a plurality of desired steering wheel angles for the vehicle, and when the sequence of the plurality of desired steering wheel angles is verified via comparison to one or more mathematical models, controlling steering of the vehicle according to the sequence of a plurality of desired steering wheel angles.
