How to improve the idle speed of Honda cRv electronic throttle?

Control function: the early electronic throttle function was relatively simple. Formally, it is a mechanical main throttle connected in series with an electronically controlled auxiliary throttle, which can only achieve a single function. Modern electronic throttle is an independent system, which can realize various control functions, which not only improves driving reliability, but also simplifies structure and reduces cost. The main control functions are as follows: a. Traction control (ASR) Traction control system is also called drive acceleration slip adjustment. Its function is to control the slip rate of the automobile during acceleration within a certain range and prevent the driving wheel from slipping quickly. Its first function is to improve traction; The second is to keep the car running smoothly. It reduces the engine power by reducing the throttle opening to achieve the control purpose. The principle is as follows: the control unit collects signals such as accelerator pedal position, wheel speed, steering angle of steering wheel, etc., calculates the slip rate, and generates corresponding control voltage signals, which are transmitted to the control unit through the data bus. According to this signal, the control unit will reduce the throttle opening to adjust the mixture flow, thus reducing the engine power. At this time, the control signal sent by the control unit to the throttle will not be affected by the driver's driving intention, so that the driver's misoperation can be avoided. B, cruise control (CCS) Cruise control system, also known as speed control system, is a device to reduce driver fatigue. When the driver turns on the system, the speed will be fixed and the driver does not have to step on the accelerator for a long time. The principle is as follows: the speed sensor inputs the speed signal to the control unit, and the control unit automatically adjusts the throttle opening according to the change of driving resistance. When the vehicle resistance increases (uphill) and the vehicle speed decreases, the throttle opening is controlled to increase, and vice versa, so as to keep the running speed stable. C. Idle speed control (ISC) Electronic throttle system cancels the idle speed control valve, but directly adjusts the throttle opening through the control unit to realize the idle speed control of the vehicle. D, reducing shift impact control According to the current vehicle speed, throttle opening, engine speed and other signals, the control unit selects the appropriate transmission ratio to realize automatic shift.
