What is the principle of BMW's electronic accelerator pedal?

Generally speaking, there are two kinds of throttle used in vehicles: cable throttle and electronic throttle. Now most cars are equipped with electronic throttle, which is more accurate than wire control. Its working principle is that there is a sliding resistor on the accelerator pedal. At that time, the depth of the accelerator pedal is expressed by the resistance value, which is transmitted to ECU, and then ECU controls the opening of the accelerator. Because this transmission process takes time, a car with an electronic throttle will feel sluggish when driving. In order to improve this situation, electron accelerators came into being.

In fact, its working principle is relatively simple. When the accelerator pedal is depressed, the signal will not be directly transmitted to the ECU, but will first pass through the electronic accelerator, and then the accelerator will amplify the signal and transmit it to the ECU. For example, stepping on the accelerator will open a certain angle according to the pedal depth. After installing the throttle, the throttle will be amplified to 2/5 of the throttle depth and transmitted to the ECU, so that the throttle will be opened to a certain angle. Simply put, the electronic accelerator confuses the ECU with the same accelerator pedal depth, amplifies the signal, and thus obtains a better acceleration feeling than before. Of course, it is simple to say, but the actual adjustment is still complicated and the effect is good.

BMW wind booster electron accelerator

After installing the electronic throttle of the wind booster, the throttle response is obviously much faster than the original, and the driving pleasure is also improved instantly. Of course, there is a reward for giving. The fuel consumption will increase by 0.5- 1 liter about 100 kilometers when installing the wind-supercharged electronic throttle, but I believe this will not have much impact. After all, 1 liter gasoline can bring a refreshing driving experience, which is really worth paying!
