Autonomous vehicle and method for controlling the same
A method for autonomous driving includes detecting an environment around a vehicle, autonomously driving the vehicle based on the detected environment, determining whether a target parking position has been set, determining an autonomous driving mode of the vehicle from among a first mode for controlling a speed of the vehicle to move the vehicle to the target parking position and a second mode for searching for an available parking position, based on a determination of the autonomous driving mode from among the first and second modes, autonomously driving the vehicle in one of the first and second modes, based on autonomously driving the vehicle in one of the first and second modes, determining whether a condition is satisfied, and based on a determination that the condition is satisfied, switching the autonomous driving mode to the other of the first and second modes.

SYSTEMS AND METHODS FOR TRACTION DETECTION AND CONTROL IN A SELF-DRIVING VEHICLE
Methods and systems are provided for traction detection and control of a self-driving vehicle. The self-driving vehicle has drive motors that drive drive-wheels according to a drive-motor speed. Traction detection and control can be obtained by measuring the vehicle speed with a sensor such as a LiDAR or video camera, and measuring the wheel speed of the drive wheels with a sensor such as a rotary encoder. The difference between the measured vehicle speed and the measured wheel speeds can be used to determine if a loss of traction has occurred in any of the wheels. If a loss of traction is detected, then a recovery strategy can be selected from a list of recovery strategies in order to reduce the effects of the loss of traction.

Independent control of vehicle wheels
An over actuated system capable of controlling wheel parameters, such as speed (e.g., by torque and braking), steering angles, caster angles, camber angles, and toe angles, of wheels in an associated vehicle. The system may determine the associated vehicle is in a rollover state and adjust wheel parameters to prevent vehicle rollover. Additionally, the system may determine a driving state and dynamically adjust wheel parameters to optimize driving, including, for example, cornering and parking. Such a system may also dynamically detect wheel misalignment and provide alignment and/or corrective driving solutions. Further, by utilizing degenerate solutions for driving, the system may also estimate tire-surface parameterization data for various road surfaces and make such estimates available for other vehicles via a network.

A system for controlling turning of vehicle may include a steering angle detection sensor; a front inner wheel speed detection sensor detecting a front inner wheel speed; a front outer wheel speed detection sensor detecting a front outer wheel speed; a rear outer wheel speed detection sensor detecting a rear outer wheel speed based on a turning direction; and a braking controller receiving detection signal of the steering angle detection sensor to determine that the vehicle turns, estimating the rear inner wheel speed in the turning direction based on detection signals of the front inner wheel speed detection sensor and the front outer wheel speed detection sensor and detection signal of the rear outer wheel speed detection sensor, and executing a mode for decreasing the estimated speed as compared to the rear outer wheel speed, as a control mode for reducing a minimum rotation radius at the time of turning.
