Control method, device and storage medium based on Hall sensor

Abstract

The present invention provides a control method, device and storage medium based on a Hall sensor, which are controlled by the following steps: monitoring the rotational speed of a vehicle based on a speed Hall sensor to generate first rotational speed voltage information; The pressure of the pedal is monitored to generate the first pressure and voltage information; if it is determined that the first pressure and voltage information has a first increasing trend, the current pressure increase rate is generated based on a preset number of first pressure and voltage information; the phase is determined based on the current pressure increase rate. The corresponding preset pressure increase interval, the first preset comparator; the control speed Hall sensor is connected to the determined first preset comparator, and the first preset comparator determines that the first rotational speed voltage information output by the speed Hall sensor is greater than When the corresponding first reference voltage information is output, a shift signal is output, and the processor controls the gear shift process of the transmission in response to the shift signal.

Description

technical field [0001] The present invention relates to the technical field of speed Hall sensors, and in particular, to a control method, device and storage medium based on a Hall sensor. Background technique [0002] The Hall voltage varies 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 value 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 for sensing, it is necessary to use a mechanical method to change the magnetic induction intensity. [0003] In the prior art, speed Hall sensors are mostly used in automobiles, such as electronic throttles, speed sensors, camshaft position sensors, etc. The speed Hall sensors output linear or non-linear output according to the changes of various st...

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
