The invention relates to the technical field of vehicle control, and discloses a vehicle driving method, device and equipment and a storage medium. The method comprises the steps that the current vehicle speed of a to-be-driven vehicle is obtained; when the current vehicle speed is lower than a first preset vehicle speed threshold value, the P3 motor serves as a driving motor to directly drive the to-be-driven vehicle; and when the current vehicle speed reaches a first preset vehicle speed threshold value, the driving motor is switched to the P1 motor to directly drive the to-be-driven vehicle. When the current vehicle speed is lower than the first preset vehicle speed threshold value, the to-be-driven vehicle can be directly driven through the P3 motor, and when the current vehicle speed reaches the first preset vehicle speed threshold value, direct driving of the P3 motor is switched into direct driving of the to-be-driven vehicle through the P1 motor. Compared with an existing mode that a P3 motor provides power in a non-efficient area at a high speed, due to the fact that an efficient area of a P1 motor is at a high speed, the driving assembly can control the P1 motor to output the same torque with low power in the efficient area of the P1 motor, and then the size and the weight of the driving assembly are reduced.

    本申请涉及车辆控制技术领域,公开了一种车辆驱动方法、装置、设备及存储介质,该方法包括:获取待驱动车辆的当前车速;在当前车速低于第一预设车速阈值时,将P3电机作为驱动电机直驱待驱动车辆;在当前车速达到第一预设车速阈值时,将驱动电机切换为P1电机直驱待驱动车辆。本申请可在当前车速低于第一预设车速阈值时通过P3电机直驱待驱动车辆,在当前车速达到第一预设车速阈值时将P3电机直驱切换为P1电机直驱待驱动车辆。相比于现有的在高速时让P3电机在非高效区提供动力,由于P1电机的高效区在高速,因此本申请可控制P1电机在其高效区以较低功率输出相同的扭矩,进而降低了驱动总成的体积以及重量。
