description

The traditional cable throttle is connected to the throttle pedal through one end of the wire and the other end is connected to the throttle. Its transmission ratio is 1:1. That is to say, how much we step on, the throttle opening angle is, but in many cases , The throttle valve should not be opened at such a large angle, so the angle at which the throttle valve opens at this time is not necessarily the most scientific. Although this method is very straightforward, its control accuracy is very poor. The electronic throttle controls the opening of the throttle through a cable or wire harness. On the surface, it replaces the traditional throttle cable with a cable, but it is not just a simple change of the connection method, but also the power output of the entire vehicle. Realize automatic control function.

When the driver needs to accelerate and step on the accelerator, the pedal position sensor transmits the sensed signal to the ECU through the cable. The ECU analyzes, judges, and sends instructions to the drive motor, and the drive motor controls the opening of the throttle to adjust The flow rate of combustible mixture, when the load is large, the throttle opening is large, and there is more combustible mixture entering the cylinder. If you use the cable throttle, you can only rely on the depth of the accelerator pedal to control the opening of the throttle. It is difficult to control the throttle. The opening angle of the valve is adjusted to reach the theoretical air-fuel ratio state, and the electronic throttle can analyze and compare various data collected by the sensor through the ECU, and issue instructions to activate the throttle actuator and adjust the throttle to the best position , In order to achieve a theoretical air-fuel ratio state close to 14.7:1 under different loads and working conditions, so that the fuel can be fully burned.

The electronic accelerator control system is mainly composed of accelerator pedal, pedal displacement sensor, ECU (electronic control unit), data bus, servo motor and throttle actuator. The displacement sensor is installed inside the accelerator pedal to monitor the position of the accelerator pedal at any time. When a change in the height of the accelerator pedal is detected, it will instantly send this information to the ECU, and the ECU will perform arithmetic processing on this information and the data information from other systems to calculate a control signal and send it to the servo motor relay through the line. The electric motor drives the throttle actuator, and the data bus is responsible for the communication between the system ECU and other ECUs. Since the electronic throttle system adjusts the throttle through the ECU, the electronic throttle system can be set with various functions to improve driving safety and comfort, the most common of which are ASR (traction control system) and speed control system (cruise control) ).
