Embodiment Construction

[0039] The invention provides an engine electronic accelerator pedal sensor module, the basic idea of ​​which is: the engine electronic accelerator pedal sensor includes a Hall sensor, a microcontroller, a filter module and an impedance conversion output module, and the microcontroller is used to generate The voltage signal V H For processing, the processed signal is output in the form of pulse width modulation (PWM), and then the PWM signal is filtered and the impedance is reduced through the filter module and the impedance transformation output module to obtain a stable and small impedance final output voltage Vo. to the engine electronic control unit (ECU). Before the electronic accelerator pedal sensor module is used, the fitting curve a between the PWM output by the controller and the final output voltage Vo is pre-measured, and the actual pedal rotation angle θ and the hall sensor output voltage V are calibrated H The relationship between the curve b; when working, the ...

Abstract

The invention discloses an electronic accelerograph pedal sensor module of an engine and a control method thereof, which belong to the field of electronic control of engine. The control method comprises the following steps of calibrating an installed electronic accelerograph pedal in way of programming a microcontroller, and converting the signals input by a Hall sensor so that the electronic accelerograph pedal can generate voltage required by manufacturers. The invention improves the production rate in process of volume production of electronic accelerograph pedals, meets the requirements of the electric control unit (ECU) of the engine on consistency, linearity and synchronization of input voltage signal with accurate output signals and strong anti-interference capability and avoids the defects caused by the method of adjusting the output voltage by using a contact-type adjustable resistor.

Description

technical field [0001] The invention relates to the technical field of engine electronic control, in particular to an engine electronic accelerator pedal sensor module and a control method thereof. Background technique [0002] With the wide application of electronic control technology in motor vehicles, new motor vehicles generally use electronic accelerators. The electronic accelerator obtains the signal of pedal position and pedal change speed through the position sensor. This signal will be received and interpreted by the engine electronic control unit (ECU). The engine electronic control unit (ECU) communicates with the vehicle control unit through the data bus to obtain other working condition information. And various sensor signals, such as vehicle speed, vehicle distance, etc., and then issue control commands to the actuator. [0003] Due to its simple structure, small size, light weight, good dynamic characteristics, long life, high reliability, and non-contact mea...
