Relevant Knowledge

The traditional cable accelerator is connected to the accelerator pedal by one end of a steel wire and the throttle valve by the other end. Its transmission ratio is 1:1, that is, the opening angle of the throttle valve is the same as how many feet we step on. However, in many cases, the throttle valve should not be opened at such a large angle, so the opening angle of the throttle valve is not necessarily the most scientific. Although this method is very direct, its control accuracy is poor. The electronic accelerator controls the opening of the throttle valve through cables or wire harnesses. On the surface, it replaces the traditional accelerator cable with cables, but in essence, it is not just a simple change in the connection mode, but it can automatically control the power output of the entire vehicle.

Generally speaking, the sensitivity of the accelerator cable is very high, but the trip computer cannot control it, but the electronic accelerator can accurately control the opening of the throttle valve through the trip computer, and it can also be automatically controlled (cruise at constant speed is achieved in this way). In daily life, some drivers will step the accelerator firmly to the bottom, and the cable accelerator will open the throttle valve according to the range of stepping down, increasing fuel injection, but this operation is unscientific, Incomplete combustion and environmental protection. When the electronic accelerator encounters this kind of operation, the ECU will intervene and open the throttle at a certain speed instead of the accelerator speed that the driver steps on. This is also the reason why the cable accelerator is more sensitive than the electronic accelerator
