An Angle Detectable Automobile Motor Control System

Abstract

An automobile motor control system capable of detecting angles. The automobile motor control system includes: a controller, an anti-reverse connection unit, an angle detection unit, a boost voltage stabilization unit, a voltage protection unit, a state detection unit, an anti-pinch unit and a motor drive unit , Anti-reverse connection unit, angle detection unit, boost voltage stabilization unit, voltage protection unit, state detection unit and anti-pinch unit are connected with the controller at the same time. The above-mentioned automobile motor control system uses an angle sensor to detect the inclination angle of the automobile, calculates the torque required to open and close the sunroof, sliding door and rolling door through the controller, and outputs PWM with a real-time adjustable duty cycle to make the motor run at a constant speed.

Description

technical field [0001] The invention relates to an automobile motor control system, in particular to an automobile motor control system capable of detecting angles. Background technique [0002] With the rapid development of our country's economy, the people's yearning for a better life has led to a rapid increase in the consumption of small cars. Coupled with the technological breakthroughs in intelligent products in recent years, automobile manufacturers and auto parts manufacturers are increasingly applying intelligent electronic control products to cars. [0003] At present, most of the sunroofs, sliding doors and rolling doors of automobiles are electrically controlled by motors. Especially the electric sliding door, compared with the traditional mechanically controlled electric sliding door, not only has a high degree of automation and a relatively stable speed, but also has a large opening width, which is convenient for passengers to enter and exit.

AI Technical Summary

Problems solved by technology

When opening or closing the electric sunroof, sliding door or rolling door, due to the influence of the gravity of the earth, the required motor rotor torque will be different in different situations. Sometimes the required torque is 1 or 2 times the normal horizontal torque, and sometimes it needs The torque is 1 / 2 or 1 / 4 of the normal horizontal torque, so the traditional automotive motor control system often has unstable speed when opening or closing the electric sunroof, sliding door or rolling door
