Vehicle Window Control with Anti-Pinch Safety

Overview

Description

This vehicle window control design integrates an MCU, buttons, DC motor, power supply, and power devices to offer comprehensive window control. It features motor forward and reverse control, window anti-pinch, and more, providing a sensitive response, fast speed, and easy operation. The system meets the automotive industry's demand for sophisticated, safety-compliant window control systems, aligning with global trends for enhanced vehicle safety and user comfort.

System Benefits:

  • Simple and effective control of the window motor ensures smooth and precise operation.
  • The current ripple algorithm supports the anti-pinch function, significantly improving passenger safety and meeting modern automotive safety standards.
  • CAN and LIN modules for automotive interfaces are integrated into the MCU, facilitating seamless integration with vehicle communication networks and reducing overall system complexity.
  • Automotive-grade high voltage, high frequency, half-bridge driver, and high current switching MOSFET.
