Problems solved by technology

[0009] On the one hand, this method does not take into account the anti-pinch area. Once the glass is stressed, it is considered to be a person or object caught, which is easy to misjudgment; on the other hand, the system is complex in structure, high in cost, and difficult to implement.

Embodiment Construction

[0028] The technical scheme of the present invention is described in further detail below:

[0029] The invention discloses a vehicle window anti-pinch control system based on a Hall sensor, which comprises a control module, a Hall sensor, a counting module and a pulse width calculation module;

[0030] The Hall sensor is arranged in the motor for controlling the lifting and lowering of the window glass, and is used to generate a square wave pulse signal corresponding to the rotation state of the rotor of the motor;

[0031] One end of the counting module is connected to the Hall sensor, and the other end is connected to the control module, which is used to calculate the number of rotations of the motor according to the square wave pulse information generated by the Hall sensor, and transmit it to the control module ;

[0032] One end of the pulse width calculation module is connected to the Hall sensor, and the other end is connected to the control module, and is used to cal...

Abstract

The invention discloses a vehicle window anti-pinch control system based on a Hall sensor. The vehicle window anti-pinch control system includes a control module, the Hall sensor, a counting module, and a pulse width calculating module, the Hall sensor is arranged in a motor for controlling the elevating of vehicle window glass and generates square-wave pulse signals corresponding to the rotating condition of a motor rotor, the counting module counts the rotation number of the motor, the pulse width calculating module calculates the armature current of the motor, and the control module controls the motor to stop when the lifting distance of the vehicle window glass is greater than the preset distance threshold and the armature current of the motor is greater than the preset current threshold. The vehicle window anti-pinch control system is simple in structure and convenient to use, and the anti-pinch system can be started immediately once the bearing force exceeds a certain amount in the anti-pinch area, so that children can be effectively prevented from being pinched.

Description

technical field [0001] The invention relates to the field of automotive electronics, in particular to a vehicle window anti-pinch control system based on a Hall sensor. Background technique [0002] Automotive electronics is the general term for car body electronic control devices and vehicle electronic control devices. Car body electronic control device, including engine control system, chassis control system and body electronic control system (body electronic ECU). The most important role of automotive electronics is to improve the safety, comfort, economy and entertainment of the car. An electronic control system composed of sensors, microprocessor MPU, actuators, dozens or even hundreds of electronic components and parts. [0003] Automobile electrification is considered to be a revolution in the development of automobile technology. The degree of automotive electronics is regarded as an important indicator to measure the level of modern automobiles, and it is the mos...
