The invention provides a vehicle speed adjusting method and device and electronic equipment. The method comprises the steps: obtaining the maximum vehicle speed and required vehicle speed of a vehicleunder the condition that fault of a mechanical system of an HMCVT is detected, and obtaining a required rotating speed initial value through calculation based on the maximum vehicle speed and required vehicle speed of the vehicle; obtaining an engine required rotating speed change value calculated according to the vehicle required acceleration value, and determining the sum of the required rotating speed initial value and the engine required rotating speed change value as a first engine required rotating speed value; and then sending the first engine required rotating speed value to an electronic control unit, so that the electronic control unit can perform vehicle speed control according to the first engine required rotating speed value. According to the invention, the original transmission ratio used when the mechanical system is normal is no longer adopted to calculate the rotating speed and the vehicle speed, the rotating speed and the vehicle speed are not limited by the currenttransmission ratio, the rotating speed and the speed of the vehicle can be adjusted as required, and the running speed of the vehicle can be increased as required.

    本发明提供了一种车速调节方法、装置及电子设备,在检测到HMCVT的机械系统故障的情况下,获取车辆最大车速以及需求车速,基于车辆最大车速以及需求车速,计算得到需求转速初始值,获取依据车辆需求加速度值计算得到的发动机需求转速变化值,将需求转速初始值和发动机需求转速变化值之和确定为第一发动机需求转速值,然后将第一发动机需求转速值发送至电子控制单元,以使电子控制单元依据第一发动机需求转速值进行车速控制。通过本发明,不再采用原有的机械系统正常时使用的传动比进行转速和车速计算,则转速和车速不受制于当前的传动比,车辆转速和速度可以依据需求调节,进而车辆行驶速度可以根据需求进行速度提升。
