Abstract
A turn control system is provided having four wheels and a steering wheel that controls the vehicle steering. A steering wheel angle sensor senses an angle of rotation of the steering wheel. An acceleration sensing device senses an acceleration demand. A wheel speed sensing device senses a wheel speed for each of the four wheels. A turn control activation switch enables the turn control system and shifts a vehicle transmission to one of a low or reverse operating gear. A brake control module calculates a target vehicle speed, a vehicle turning geometry, and target wheel speeds. A braking torque command signal is generated for modulating the brake torque. An engine torque command signal is generated for modulating an engine torque for producing the target vehicle speed. A respective additional braking torque is applied to at least one of the wheels for reducing the vehicle turning radius while maintaining the vehicle target speed.
