The present disclosure provides a system and method for vehicle turn radius reduction. A vehicle control system for reducing a turn radius of a vehicle may include a controller and a torque control module operably coupled to the controller and front wheels of a front axle of the vehicle and rear wheels of a rear axle of the vehicle. The controller may also be operably coupled to components and/or sensors of the vehicle to receive information including wheel speeds and steering wheel angles. The torque control module is operable in response to control of a controller to apply a negative torque to an inboard rear wheel during a turn, and to apply a positive torque to the front axle during the turn to compensate for the negative torque applied to the inboard rear wheel, thereby reducing the turning radius based on the steering wheel angle and the vehicle speed.

    本公开提供了“用于车辆转弯半径减小的系统和方法”。一种用于减小车辆的转弯半径的车辆控制系统可包括控制器和扭矩控制模块,所述扭矩控制模块可操作地联接到所述控制器以及所述车辆的前车桥的前轮和所述车辆的后车桥的后轮。所述控制器还可以可操作地联接到所述车辆的部件和/或传感器,以接收包括车轮转速和方向盘角度的信息。所述扭矩控制模块可以响应于控制器的控制而操作以在转弯期间向内侧后轮施加负扭矩,并且在所述转弯期间向所述前车桥施加正扭矩以补偿所述施加到所述内侧后轮的负扭矩,从而基于所述方向盘角度和所述车辆速度而减小所述转弯半径。
