Abstract

The invention relates to electric current measurement technology, in particular to a hall sensor temperature compensation method in an automobile, a hall sensor based on a principle of the compensation method and an automotive electronic control system with the hall sensor adopted. The hall sensor temperature compensation method used for the automobile includes the following steps: a voltage measurement signal of the hall sensor is received; a temperature measurement signal near the hall sensor is obtained; and a current-to-be-measured modification value Im is calculated.

Description

technical field [0001] The invention relates to current measurement technology, in particular to a temperature compensation method of a Hall sensor in an automobile, a Hall sensor based on the principle of the compensation method and an automotive electronic control system using the Hall sensor. Background technique [0002] The demand for current measurement in the automotive industry has increased dramatically in recent years. The occasions that require current measurement in vehicles mainly include the field of motor control and battery monitoring, where accurate and real-time current measurement is one of the prerequisites for optimal control. The Hall sensor is a commonly used current sensing element. The material for making the Hall element is generally a semiconductor material (such as silicon, germanium, indium arsenide, and indium antimonide, etc.), which makes the output of the Hall element linearly affected by temperature. Greater impact. Considering that the te...
