The invention provides a vehicle speed calculation device and method and a vehicle. The vehicle speed calculation device is used for calculating the vehicle speed of a vehicle, the vehicle comprises wheels, and the vehicle speed calculation device comprises: wheel speed sensors used for detecting and outputting rotating speed signals of the wheels; a first calculator which is in communication connection with the wheel speed sensor and used for receiving the rotating speed signal output by the wheel speed sensor and calculating the vehicle speed according to the rolling radius of the wheel and the tooth number of the front axle gear ring and the rear axle gear ring; and a second calculator which is in communication connection with the first calculator and is used for acquiring the vehicle speed output by the first calculator, inputting a corresponding pulse signal to the instrument according to the PPK value of the instrument (the vehicle runs for 1 kilometer and the pulse number output by the sensor) and the ABS, and finally displaying the vehicle speed on the instrument. According to the invention, the wheel speed signal is finally converted into the required vehicle speed signal, so that the cost is reduced compared with the vehicle speed signal input by the original vehicle speed sensor.
本发明提供了一种车速计算装置、方法和车辆。车速计算装置用于计算车辆的车速,车辆包括车轮,车速计算装置包括:轮速传感器,用于检测并输出车轮的转速信号;第一计算器,与轮速传感器通讯连接,用于接收轮速传感器输出的转速信号,并根据车轮滚动半径以及前桥后桥齿圈齿数计算出车速;第二计算器,与第一计算器通讯连接,用于获取第一计算器输出的车速,根据仪表的PPK值(车辆行驶1公里,传感器输出的脉冲数),ABS输入相应的脉冲信号给仪表,最终在仪表上显示车速。本发明通过获取轮速信号最终转换为所需要的车速信号,相比原有的车速传感器输入车速信号,降低了成本。
