The invention discloses a vehicle steering torque distribution method and device and a storage medium. The method comprises the steps that a target transmission torque and a road adhesion coefficient are obtained, the target transmission torque is used for representing the torque transmitted from a vehicle rear shaft of a target vehicle to a vehicle front shaft, and the road adhesion coefficient is used for representing the resistance condition between the target vehicle and a road surface; correcting the target transmission torque by using the road adhesion coefficient to obtain a correction result; and performing steering torque distribution between the vehicle front axle and the vehicle rear axle based on the correction result. The technical problem that steering interference and control stability are difficult to balance during vehicle steering in the prior art is solved.

    本发明公开了一种车辆转向扭矩分配方法、装置以及存储介质。其中,该方法包括:获取目标传递扭矩和路面附着系数,其中,目标传递扭矩用于表示由目标车辆的车辆后轴向车辆前轴传递的扭矩,路面附着系数用于表示目标车辆与路面之间的阻力情况;利用路面附着系数对目标传递扭矩进行修正,得到修正结果;基于修正结果在车辆前轴和车辆后轴之间进行转向扭矩分配。本发明解决了相关技术中在车辆转向时难以平衡转向干涉和操控稳定性的技术问题。
