Abstract
The invention relates to an electronic control method of a mechanical throttle, which comprises an electronic accelerator pedal, electronic throttle control (ETC), AD (analog-digital) signal conversion, DA (digital-analog) signal conversion, a stepping motor analog circuit, an air inflow processing algorithm, an electronic throttle target opening and an ETC control algorithm, belongs to the field of automotive electronics, and has the function that the mechanical throttle can replace the electronic throttle without changing the situation of the original ECU.
Description
Technical field
The present invention relates to a kind of controlling method of mechanical closure, especially can replace electronic throttle in the situation that does not change former ECU.
Background technique
The machinery closure is a device on the engine aspirating system, is the steel disc of a circle, and there is an axle centre; Open and close by acceleration cable control; Be made up of valve block position transducer and stepper motor, idling is that step motor control is arranged, and throttle line pulling valve block is opened during oiling; Closure valve block position transducer also and then rotates (it is a variable resistor), changes its resistance size and exports to ECU changing voltage signal then.ECU monitors the function of system, if find fault, with the lighting system fault indicating lamp, there is fault in prompting driver system.
The research work of electronic throttle originates from the seventies in 20th century, begins the eighties to have product to come out, and over nearly 10 years, the research to electronic throttle has abroad obtained very fast development.Development trend can be summarized as: on control strategy, develop into nonlinear Control by linearity control; Develop into independently electronic throttle system by the auxiliary electron closure;, take into account and improve power character, Economy, control stability, emission performance and riding comfort to integrated various control function from single control function development.External many companies have done deep research and development to electronic throttle system, such as German Bosch, Pierburg; U.S. Delphi, Visteon, Japanese Toyota; Hitachi, Denso, Italian Marelli etc. have released the medium-to-high grade car that tandem product is applied to various brands.
The advantage of electronic throttle: the great advantage of (1) control system of electronic throttle valve is to realize the output of the FR best torque of motor.(2) accurately control throttle opening.At first various work informations and sensor signal are made judgement and processing, then calculate best throttle opening, reach corresponding throttle opening angle by drive motor control closure again by ECU.(3) improved the emission performance of motor.(4) has higher vehicle driving reliability.(5) can select the different working pattern.(6) can obtain height above sea level compensation.
Along with the development of electronic throttle technology and the practicability and the reliability of electronic throttle; There is the automobile of the mechanical closure of a lot of uses to change electronic throttle at present; The present invention is exactly a kind of controlling method of mechanical closure, replaces with electronic throttle at following mechanical closure of the prerequisite that does not change the ECU control strategy.
Summary of the invention
The machinery closure is with the different of electronic throttle: 1 mechanical closure has Stepping Motor Control; Electronic throttle does not have the control 2 mechanical closures of stepping electronics to close at the idling mode lower valve; Be the air inflow of regulating the idling by-pass hole through idle speed step motor, electronic throttle valve block of under idling mode itself has certain slit.
Content of the present invention is the algorithm of analog circut through air inflow of signal and stepper motor of the APS of electronic accelerator pedal; Calculate electronic throttle target aperture; Through with the contrast of the TPS feedback signal of the reality of electronic throttle; Control algorithm control electronic throttle through electronic throttle drives the aperture control of carrying out electronic throttle, and the signal of electronic accelerator pedal is constant to be input to original ECU.
This electronic control method comprises: electronic accelerator pedal, electronic throttle ETC, AD signal conversion, DA signal conversion, stepper motor analog circut, air inflow Processing Algorithm, electronic throttle target aperture and ETC control algorithm.The APS signal of electronic accelerator pedal is input to the air inflow Processing Algorithm through the AD signal conversion; The analog circut that former ECU stepper motor signal is input to stepper motor is being input to signal the air inflow Processing Algorithm; The target aperture that the air inflow Processing Algorithm combines two calculated signals to go out electronic throttle compares the control signal of exporting electronic throttle at the signal through ETC control algorithm and electronic throttle then and drives to ETC, and the signal of electronic accelerator pedal is input to former ECU in the conversion through the DA signal.The signal of former ECU is input to the stepper motor analog circut, and the electronic throttle input signal is given the ETC control algorithm, accepts the signal of ETC control algorithm simultaneously.
