Optimum Regulation Method of Electronic Throttle Accelerator

　　By collecting the position sensor signal of the throttle pedal, the reorganized throttle signal is transmitted to the computer to improve the response performance of the engine, thereby improving the throttle sensitivity, accelerating the starting speed, improving the instantaneous speed-up performance of the vehicle, avoiding sudden forward movement of the vehicle, and avoiding engine carbon deposition. The product has exclusive design and safety functions, and can be set up according to the driving habits and needs of the owner. And the installation is very simple and fast. It can be used only by connecting the line group with the electronic throttle joint. It can be installed on the whole line of electronic throttle system! __________ At present, most of the automobiles are designed with electronic throttle. The depth of throttle angle will affect the opening of butterfly cover. Because of the slow response of electronic throttle in the original factory, the response can be improved by adjustable electronic throttle regulator. Make your car a little more fun! The principle of electronic throttle and wire-drawing throttle is based on various reasons such as environmental protection, economy and controllability. Electronic throttle is widely used in the market. The so-called electronic throttle is aimed at the former wire-drawing throttle. The traditional wire-drawing throttle directly connects the throttle pedal with the throttles by thin steel rope. The depth of the throttle pedal is directly corresponding to the opening and closing size of the throttles, and the electronic throttle is submerged. With pull wire, through installing a potentiometer (variable resistance) in the pedal, the depth of the throttle is transformed into the resistance value. The electronic system of automobile indirectly determines the depth of the throttle pedal by sampling the resistance value. Finally, the throttle opening is controlled by step motor driven by ecu. It is not difficult to find that the characteristics of pull-wire throttle are simple system and straight control. Then, the throttle pedal and throttle openings are 1:1; while the electronic throttle pedal only represents the driver's operating intention, and the final throttle control is handed over to the driver.

　　Characteristics of ECU control throttle in electronic throttle vehicle

　　In the electronic throttle model, when ECU controls the throttle, the depth of throttle trampling and the condition of the vehicle are synthesized to analyze, and finally the appropriate throttle opening is calculated. When the driver starts with a sudden acceleration (stepping the pedal to the bottom), the ECU will analyze the current speed, throttle size and so on. Considering the fuel economy and emission rationality, it will appropriately limit the throttle opening range, and control the injection system to limit the maximum injection of fuel from the injector. In this way, the driver feels that there is obviously a delay after the throttle is stepped down before the car starts to exert force, which is called throttle lag. Therefore, throttle hysteresis is actually caused by the restriction of the instantaneous power output of the engine by the ecu. Of course, it also brings benefits - saving fuel and protecting the environment. But the electronic throttle is not just used to limit the output of engine power. When the car runs up, if you step on/release the pedal board at a depth of 1/3, you can feel the obvious refueling/refueling effect of the car, which is almost equivalent to completely stepping on/unlocking the throttle. What happens? This is the case where the ECU assists the driver to speed up/decelerate quickly according to the current condition. Therefore, the ECU will help the driver to achieve the desired acceleration/deceleration operation according to the condition of the vehicle, making it easier for the driver to operate the accelerator pedal.

　　Working principle

　　(1) To amplify the throttle signal and enhance the so-called "acceleration" of the static response electronic throttle accelerator is mainly achieved by improving the sensitivity of the throttle response, which amplifies the input throttle signal by 50%. That is to say, 33% of the throttle signal at the end of the pedal is useless at any time, and the accelerator output is full throttle when the driver pushes 66% of the pedal down, which increases the sensitivity of the throttle response by 50%. However, electronic throttle accelerator does not reduce the classification of throttle signal as many people say. In fact, throttle signal is still steplessly adjusted, only from the previous 1:1 to 1:1.x, x is the signal amplification factor.

　　(2) When the accelerator pedal is depressed, the accelerator will calculate the change rate of the accelerator signal according to the step-down amplitude and time. The faster the change, the stronger the acceleration requirement, the higher the change rate of the accelerator will be. The final effect is that the acceleration dynamic response will be better accordingly.

　　(3) The ECU which provides virtual driving style for ECU to adjust engine parameters generally has adaptive driving style. If the driver often steps on the accelerator (commonly known as pull speed), the ECU will gradually think that the driver's style tends to be "fierce", so the engine will adjust the throttle and fuel injection system slowly to get the best adjustment of the engine in this style. Parameters. After using the electronic accelerator, even if the engine is driven according to the previous "mild" driving style, the engine will still get "intense" driving experience, which is equivalent to deceiving the ecu. Over time, the engine will automatically modify its parameters to adapt to the style.

　　On Electronic Throttle Controller

　　Simply put, the electronic throttle controller is an upgraded version of the electronic throttle accelerator nickname, both of which work in the same principle and function; the only thing is that the electronic throttle controller has a display screen, which can be selected at a glance. The two have the same points. (1) The working principle is the same. All of them are realized by improving the sensitivity of throttle response, and the input throttle signal will be amplified by 50%. (2) The same applies to the models. All of them are suitable for electronic throttle design. (3) The installation method is the same. They are mounted on the throttle pedal ports of the car. Two
