Digital and analog two-signal electronic accelerator and mistake stepping prevention method thereof

Abstract

The invention discloses a digital and analog two-signal electronic accelerator and a mistake stepping prevention method of the digital and analog two-signal electronic accelerator. The electronic accelerator comprises a pedal assembly, a pair of magnetic steel, a pedal position sensor and a signal processing circuit box. The pair of magnetic steel are correspondingly arranged on a rotating shaft of the pedal assembly correspondingly and rotated along with the rotating shaft. The pedal position sensor is arranged at the position where the pedal assembly is located, and used for sensing the stroke of a pedal and outputting corresponding frequency digital signals and analog signals to the signal processing circuit box. The signal processing circuit box is used for carrying out photoelectric isolation processing, frequency measurement, scale conversion and digital-to-analog conversion on the received frequency digital signals and outputting the signals as main signals and used for removing interference on the received analog signals and outputting the signals as auxiliary signals. When the time spent by the accelerator pedal position signals from the smallest value to the largest value is smaller than a set value, the signal processing circuit box outputs idling signals as main signals, and the accelerator is prevented from being used as a brake. The digital and analog two-signal electronic accelerator is simple in structure, convenient to use and high in popularization value.

Description

technical field [0001] The invention relates to the field of electronic accelerators, in particular to a digital-analog dual-signal electronic accelerator and a method for preventing wrong stepping thereof. Background technique [0002] At present, the electronic accelerator of automobiles and tractors is combined with a pedal position signal sensor and a signal processing circuit to be installed on the accelerator pedal assembly. This kind of electronic accelerator has a large structure, which is not conducive to the effective space installation arrangement. [0003] However, traditional field tractors are equipped with a hand throttle device, which is costly and inconvenient to operate, and increases the space for hand throttle arrangement. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a digital-analog dual-signal electronic throttle and its anti-misstepping method for the defects involved in the background ...
