The invention provides a vehicle in-situ turning-around control method, device and equipment and a storage medium, and relates to the technical field of vehicle control. The method comprises the steps that when a vehicle enters a U-turn mode, a first driving torque, a second driving torque and a brake hydraulic value are determined according to steering information of the vehicle and physical parameters of a vehicle body of the vehicle; outer rear side wheels of the vehicle are controlled to be locked, and the outer rear side wheels serve as the rotation center; an outer front side wheel and an inner front side wheel of the vehicle are controlled to rotate forwards according to the first driving torque, braking hydraulic pressure with the braking hydraulic pressure value is applied to the inner front side wheel of the vehicle, and an inner rear side wheel of the vehicle is controlled to rotate backwards according to the second driving torque; wherein the inner front side wheel, the outer front side wheel, the inner rear side wheel and the outer rear side wheel are determined according to steering information of the vehicle. According to the embodiment of the invention, the turning radius of the dual-motor four-wheel-drive electric vehicle can be further reduced.

    本申请提供一种车辆原地调头控制方法、装置、设备及存储介质,涉及车辆控制技术领域。该方法包括:在车辆进入调头模式时,根据车辆的转向信息以及车辆车体的物理参数确定第一驱动力矩、第二驱动力矩以及制动液压值;控制车辆的外后侧车轮抱死,并以外后侧车轮为旋转中心;按照第一驱动力矩控制车辆的外前侧车轮和内前侧车轮向前转动,并对车辆的内前侧车轮施加制动液压值大小的制动液压,以及按照第二驱动力矩控制车辆的内后侧车轮向后转动;其中,内前侧车轮、外前侧车轮、内后侧车轮以及外后侧车轮根据车辆的转向信息确定。根据本申请实施例,能够进一步减小双电机四驱电动车的转弯半径。
