A vehicle control system for reducing turn radius of a vehicle may include electric motors associated with front and rear wheels of the vehicle. The system may further include a plurality of vehicle sensors to receive information including driving surface type, vehicle speed and handwheel position. The system may also include a controller operably coupled to the electric motors and the sensors to control wheel slip during a turn based on the driving surface type, the vehicle speed and the handwheel position.

A method of controlling posture of a vehicle is provided to determine a minute tendency of understeer or oversteer of the vehicle and to control the posture of the vehicle when recognizing the minute tendency of the understeer or oversteer while driving the vehicle straight. The includes determining whether torque is applied to drive wheels while driving the vehicle and acquiring equivalent inertia information of a drive system in real time based on drive system operation information in response to determining that the torque is being applied to the drive wheels. The understeer or oversteer of the vehicle is determined from the equivalent inertia information obtained in real-time.

A motor control system for a commercial vehicle having an electric axle includes: first and second motors disposed in a rear-wheel electric axle; an accelerator position sensor for detecting a degree to which an accelerator is depressed; a wheel speed sensor detecting a wheel speed change; and a controller determining a driver's required torque on the basis of detection signals of the accelerator position sensor and the wheel speed sensor and then controlling a torque of the first motor in such a manner as to approach target torque for satisfying the driver's required torque and at the same time either controlling either a torque of the second motor to a level that compensates for a torque error of the first motor or controlling the torque of the first motor and the torque of the second motor at alternating fixed duty ratios.

Methods and systems for operating axles of a vehicle are provided. In one example, a propulsion source of a first axle is operated in a torque control mode at a first torque and a propulsion source of a second axle is operated in a torque control mode at a second torque. Torque of the propulsion sources may be adjusted as a function of steering angle.

A method of providing an interactive personal mobility system, performed by one or more processors, comprises determining an initial pose by visual-inertial odometry performed on images and inertial measurement unit (IMU) data generated by a wearable augmented reality device. Sensor data transmitted from a personal mobility system is received, and sensor fusion is performed on the data received from the personal mobility system to provide an updated pose. Augmented reality effects are displayed on the wearable augmented reality device based on the updated pose.

A method for controlling torque vectoring of an xEV includes detecting vehicle speed information using speed sensors mounted in the xEV, and estimating a vehicle speed of the xEV in driving based on the detected vehicle speed information, setting a state of the xEV based on the estimated vehicle speed, determining whether there is an intervention request based on the set state of the xEV, detecting a steering angle of the xEV when the intervention request is rejected, and when the detected steering angle of the xEV is within a predetermined reference angle range, determining the xEV as being in a first slip state in which the xEV slips in a longitudinal direction, and resetting the vehicle speed of the xEV through output of a torque vectoring (TV) motor mounted in the xEV.
