effect
The main function of the accelerator pedal is to control the opening of the throttle, thereby controlling the power output of the engine. The accelerator pedal of some cars is connected to the throttle of the engine through a throttle cable or lever. When the driver steps on the accelerator pedal, the throttle is directly controlled. Nowadays, electronic accelerators are used in many vehicles, and the accelerator pedal and throttle are no longer connected by the accelerator cable. A displacement sensor is installed on the accelerator pedal of the electronic accelerator. When the driver steps on the accelerator pedal, the ECU will collect the opening change and acceleration of the displacement sensor on the pedal, and judge the driver’s driving intention according to the built-in algorithm, and then give the engine throttle The control motor sends corresponding control signals to control the power output of the engine.
Arrangement form
There are now two types of accelerator pedals, "floor type" and "suspension type".
The floor pedal is located at the bottom of the pedal, so the soles of the feet can be stepped on, and the pedal itself is a fulcrum. The calf and ankle can control the pedal more easily, which correspondingly improves the accuracy of the pedal control under the foot and reduces fatigue.
The suspended accelerator pedal has a relatively simple (thin) lower structure because the shaft is located at the top of the bracket. This also makes its pedaling method lighter, and the pedal bracket can be designed to be made of iron rods, so to a large extent Can save the cost, so the average manufacturer prefers to use this pedal. Compared with the floor pedal, the suspension accelerator pedal can only provide a fulcrum for the forefoot, so driving the calf for a long time will be more rigid, which is why most people complain that the suspension pedal is tired after driving for a long time.
