Car Window Control
The lifting of the automobile electric window can be controlled by a main switch and a separate window switch respectively, and the lifting of the window is realized by changing the current flow direction of the motor through the control switch so as to change the running direction of the motor.
The input of the key is sampled by the AD conversion module, and the position of the key can be judged. The low-side switch drives and controls the relay switch to control the bridge arm switch of the motor to control the rotation of the motor; the high-side switch drives and controls the LED switch for the backlight of the key. The LIN transceiver is connected to the LIN bus.
In traditional fuel vehicle applications, MCU is only suitable for engine control, battery management, entertainment control and other local functions, but with the development of the "new four modernizations" of automobiles, the application scope of MCU in the automotive field is becoming wider and wider.
