SAIC brand original clutch pedal switch for MAXUS V80 C0002415

What does the clutch pedal switch do?
The function of the clutch pedal switch is to ensure the smooth start of the car, achieve smooth shifting, and prevent overloading of the transmission system. The switch on the clutch pedal is a normally closed switch. When the clutch is depressed, the switch closes. The engine control unit has no signal from the clutch that the engine should be disconnected. Therefore, the ignition advance angle is reduced to reduce fuel injection and reserve power.

After the engine is started, before the automatic start, the driver first steps on the clutch pedal to disengage the clutch, disconnecting the engine from the drive train, then shift the transmission to gear, and then gradually release the clutch pedal to gradually engage the clutch. During the engagement process, the hindered torque of the engine gradually increases, so the accelerator pedal should be stepped down gradually at the same time, that is, the fuel supply to the engine should be gradually increased, so that the engine speed is always kept at the lowest stable speed without stalling. At the same time, as the degree of engagement of the clutch gradually increases, the torque transmitted by the engine to the drive wheels through the transmission system gradually increases. When the traction is sufficient to overcome the starting resistance, the car begins to move from a standstill and accelerates gradually.

In the process of driving, in order to adapt to the changing driving conditions, the transmission system often needs to change to different gears to work. The gear shift of the gear transmission is generally driven by pushing out one gear pair of the original gear by shifting the gear or other shifting mechanisms, and then making the gear pair of the other gear work.
