How to lift the speed limit of Wuling new card double row 20 19

Pacific Auto Network 20 19 Wuling new card double-row lifting speed limit. It is recommended to go to 4S shop to let professionals lift the speed limit with professional equipment. For the safety of drivers and passengers and the service life of cars, it is best not to lift the speed limit. The critical value of the speed limiter has been set when the vehicle leaves the factory, and generally cannot be changed.

The function of electronic speed limiter is to limit overspeed and prevent accidents caused by overspeed. The electronic speed limiter can monitor the vehicle speed in real time. When the speed reaches a certain value, it will control the speed of the fuel supply system and the engine. At this time, even if the accelerator pedal is pressed, the oil supply system will not supply oil. Ensure the safety of drivers.

Because the early cars didn't have the speed limit function, the design should consider two different requirements: installation before leaving the factory and installation after sale. The speed limiter should be installed flexibly so as not to damage the integrity and reliability of the car. In order to design such a speed limiter, it is first necessary to understand the working principle of the automobile throttle system. The general electronic automobile accelerator system includes accelerator pedal, pedal sensor, electronic control unit (ECU), motor and accelerator mechanism.

The driver presses the accelerator pedal according to the driving power, and the accelerator pedal position sensor converts the collected accelerator pedal position signal into an electrical signal, which is transmitted to the electronic control unit, and the electronic control unit realizes the adjustment of the accelerator through the motor, thus realizing the complete electronic control of the accelerator.
