The invention relates to a vehicle speed limiting method and device, computer equipment, a storage medium and a product. The method comprises the steps that when the rotating speed of a driving motor currently driving a vehicle to run is larger than a rotating speed threshold value, first driving limiting power is determined according to parameters of the driving motor and the rotating speed threshold value, and the driving motor is one of a first motor and a second motor; according to the first driving limiting power, the first power generation limiting power of a power generation motor is determined, and the power generation motor is the other one of the first motor and the second motor except the driving motor; and according to the first power generation limiting power and the parameters of the planetary gear mechanism corresponding to the power generation motor and the engine, the first starting limiting power of the engine is determined, and the output power of the engine is controlled to be smaller than or equal to the first starting limiting power. By the adoption of the method, the situation that the battery is overcharged can be avoided while the power of the driving motor is limited to limit the speed of the vehicle, and the service life of the battery is prolonged.

    本申请涉及一种车速限制方法、装置、计算机设备、存储介质和产品。该方法包括:在当前驱动车辆运行的驱动电机的转速大于转速阈值时,根据驱动电机的参数、转速阈值,确定第一驱动限制功率,其中,驱动电机为第一电机和第二电机中的一个;根据第一驱动限制功率,确定发电电机的第一发电限制功率,其中,发电电机为第一电机和第二电机中除驱动电机外的另一个;根据第一发电限制功率、发电电机和发动机分别对应的行星齿轮机构的参数,确定发动机的第一发动限制功率,并控制发动机的输出功率小于或等于第一发动限制功率。采用本申请的方法,在限制驱动电机的功率实现对车辆进行限速的同时,也能够避免出现电池过充的情况,提高了电池的使用寿命。
