The invention provides a vehicle turning control device, a vehicle and a vehicle turning control method, and relates to the technical field of auxiliary driving. The vehicle turning control device can determine the target rotating speed ratio of wheels on the inner side and the outer side of the vehicle according to the steering angle of the vehicle and output a corresponding PWM control signal so that a differential can control the rotating speed ratio of the wheels on the inner side and the outer side according to the PWM control signal, and the larger the rotating speed ratio of the wheels on the inner side and the outer side is, the smaller the turning radius of the vehicle is. When the steering angle of the vehicle changes, the rotating speed ratio of the inner side wheel and the outer side wheel of the vehicle changes accordingly, so that the purpose that the turning radius is automatically adjusted by dynamically adjusting the rotating speed ratio of the inner side wheel and the outer side wheel, the vehicle with the original insufficient turning radius can smoothly turn on a narrow road is achieved, and a driver can easily control the vehicle to turn.
本申请提供了一种车辆转弯控制装置、车辆和车辆转弯控制方法,涉及辅助驾驶技术领域。其中,车辆转弯控制装置,可以根据车辆的转向角,确定车辆的内外侧车轮的目标转速比,并输出对应的PWM控制信号,以使差速器按照该PWM控制信号控制内外侧车轮的转速比,内外侧车轮的转速比越大,车辆的转弯半径越小。在车辆的转向角变化时,车辆的内外侧车轮的转速比会随之变化,从而达到通过动态调整内外侧车轮的转速比来自动调整转弯半径,使原本转弯半径不够的车辆,可以在狭窄道路顺利转弯的目的,还有助于司机更轻松控制车辆进行转弯。
