The present invention can realize that not only the signals collecting function can also realize the control function to hybrid-electric car, and is as follows:

1, AIN1-AIN4 four tunnel simulating signals input altogether.With accelerationpedal position signal 1 AIN1 is the collection that example is introduced this four tunnel simulating signal.Accelerationpedal position signal 1 AIN1 is input to the voltage that controller is 0-5V, the magnitude of voltage correspondence degree of depth that depressed of accelerator pedal.AIN1 0-5V voltage is exported by AOUT after isolating by the AIN input of the circuit linearity insulating circuit of Fig. 8 after accurate conditioning again, signal after the isolation is input to MCU by the ADCIN of the central controller U1 among Fig. 2 and carries out the A/D conversion, and central controller U1 is worth to determine the degree of depth that accelerator pedal is depressed by this.

2, AOUT1-AOUT4 four tunnel simulating signals output.With electric weight pilot lamp control signal is the output that example illustrates this four tunnel simulating signal.Electric weight pilot lamp control signal is the simulating signal of a 3V-8V.What of the corresponding batteries of electric automobile electric weight of number that pilot lamp lights the height of output voltage drive.At first the central controller U1 among Fig. 2 sends tobus driver chip 14 by data line XD (0-15) with data and latchs, through by the DB (0-11) of thisbus driver chip 14 12 bit data being delivered to D/A conversion chip 16 after the bus driver, each road by address wire and control bus decoding back control D/A need new data more unit output.Because the D/A Voltage Reference is 2.5V, exports 0-5V after 2 times of amplifications.Through handle back output 3-8V voltage as Fig. 9, output to CON35 after isolating as Fig. 8.

3, the IN01-IN04 measurement of totally four road frequency signals.Output shaft of gear-box tach signal IN03 is a frequency signal.By the FIN of Fig. 5 input because input sinusoidal signal waveform, through LM339 relatively after, signal is 12V greater than 0 o'clock output high level, signal level is 0 smaller or equal to 0 o'clock output low level, IN obtains square-wave signal thus, IN is output.Again with this IN signal by the IN of Fig. 4 input, output to by IO through isolating after that central controller U1 catches in the mouth among Fig. 2, by the rising edge detection signal of software, according to definite wheel box input shaft rotating speed of the mistiming of two rising edges at each signal.
