[0077] Example
[0078] figure 1 It is the overall structure block diagram, with the microcontroller unit as the core. The microcontroller unit integrates AD converter, CAN bus controller, LIN bus controller, pulse input capture unit, EEPROM memory and digital I / O. With some peripheral interface circuits and power control units.
[0079] figure 2 It is a switch signal acquisition circuit unit, which realizes the protection of the controller itself by voltage conversion, and transmits the input signal to the microcontroller unit. These switches include key on and off, gears P, D, N, R, and air conditioning cooling. , Warm, brake switch.
[0080] image 3 For the analog signal acquisition circuit unit, the input signal is collected by an operational amplifier, which stabilizes the input signal and also isolates the microcontroller unit. This circuit is connected to the analog signal to be collected, and the output is connected to the multi-channel switch of the microcontroller unit'...
