Control method and device based on Hall sensor and storage medium

Abstract

The invention provides a control method and device based on a Hall sensor and a storage medium. Control is conducted through the following steps that the rotating speed of a vehicle is monitored based on a speed Hall sensor to generate first rotating speed voltage information, and the pressure of a vehicle accelerator pedal is monitored based on a pressure Hall sensor to generate first pressure voltage information; if it is judged that the first pressure and voltage information has the first increasing trend, the current pressure increasing rate is generated based on the preset number of first pressure and voltage information; the first preset comparator is used for determining a corresponding preset pressure increasing interval based on the current pressure increasing rate; and the speed Hall sensor is controlled to be communicated with the determined first preset comparator, the first preset comparator outputs a gear shifting signal when judging that the first speed voltage information output by the speed Hall sensor is larger than the corresponding first reference voltage information, and the processor responds to the gear shifting signal to control gear shifting processing of the gearbox.

Description

technical field [0001] The present invention relates to the technical field of speed Hall sensors, in particular to a control method, device and storage medium based on Hall sensors. Background technique [0002] The Hall voltage changes with the strength of the magnetic field. The stronger the magnetic field, the higher the voltage, the weaker the magnetic field, and the lower the voltage. The Hall voltage is very small, usually only a few millivolts, but it is amplified by the amplifier in the integrated circuit. This voltage can be amplified enough to output a stronger signal. If the Hall integrated circuit is used as a sensor, it is necessary to use a mechanical method to change the magnetic induction intensity. [0003] In the prior art, the speed Hall sensor is mostly used in automobiles, such as electronic throttle, speed sensor, camshaft position sensor, etc., through the speed Hall sensor to output linear or nonlinear Voltage information, the controller at the car...

Problems solved by technology

[0004] Most of the current cars are automatic transmission cars. When the car shifts gears, it is determined according to the speed of the engine. The speed of the engine is obtained based on the voltage information output by the speed Hall sensor. The earlier the shift, the slower the speed of the vehicle and the more energy-efficient it is. , Fuel saving, weak and late shifting, more energy consumption and cost, the car's processor will control the shifting of the vehicle based on the voltage information output by the speed Hall sensor according to the pre-configured shifting logic, but its setting is relatively simple and cannot be based on More suitable control based on the user's operating habits and the voltage information of the speed hall sensor
