Abstract

The present invention relates to the technical field of pressure sensors, and discloses a pressure sensor-based temperature compensation method, device, equipment, and storage medium. The method includes: obtaining the initial pressure-voltage characteristic curve of the pressure sensor, and obtaining the preset temperature The clutch oil circuit pressure value output by the pressure sensor and the atmospheric pressure value output by the engine on the target vehicle, the first pressure compensation value and the basic pressure-voltage characteristic curve are obtained according to the clutch oil circuit pressure value and the atmospheric pressure value, according to The basic pressure-voltage characteristic curve performs temperature compensation on the initial pressure-voltage characteristic curve of the pressure sensor, so that the pressure value of the clutch oil circuit and the atmospheric pressure value are compensated, and compensated to the pressure-voltage characteristic curve at each temperature point, It can compensate the output error of the pressure sensor due to its own temperature characteristics, and avoid inaccurate control of the hydraulic module and clutch due to the temperature error of the sensor.

Description

technical field [0001] The present invention relates to the technical field of pressure sensors, in particular to a pressure sensor-based temperature compensation method, device, equipment and storage medium. Background technique [0002] The pressure sensor in the automatic transmission will be immersed in the transmission fluid during normal operation, and the temperature of the sensor will be continuously changed by the influence of the temperature of the oil. When the temperature changes, the electronic components inside the pressure sensor have different temperature characteristics, causing the final output of the sensor to change due to the influence of temperature, thus exhibiting certain temperature characteristics. However, in a normal hydraulic system, pressure-current self-learning cannot eliminate such sensor deviation caused by temperature. [0003] Therefore, in the background art, there is a technical problem of how to compensate the output error of the press...
