Title The Design of Electric Controller For Automobile Rear Door

Abstract In order to achieve the control of opening/closing automobile tail gate by one click and make it smooth。 I choose TMS320 F2812 chips as the main control chip and regulate motor steering and speed by detecting the valid input of opening and closing signal。 In motor operation process, the controller calculate the speed of motor through the input Holzer signal and adjust the speed of DC motor through changing the PWM signal using PID, so that the motor rotation will reach a stable state。 And the design of the current detection module can prevent the operation current from being too large and it will be able to protect the motor and personnel safety。 According to the system requirements, the PCB of hardware design is carried out。 I have tested the function and stability of the hardware design。 Finally, the design of the whole tail gate control system is realized。 And the actual test results show that the system is simple and effective with stable operation and short response time and achieve the design requirements。
