The voltage comparison circuit comprises a resistor R19, a resistor R27 and a voltage stabilizing diode D4. A 5V power supply generated by a power supply circuit in the power distribution box is connected with a voltage-stabilizing diode D4 through a resistor R19; a comparison voltage is generated across zener diode D4 from a 5V supply via R19. The resistor R19 is also connected with an operational amplifier through a resistor R27; the resistor R19 obtains the reference voltage from the voltage stabilizing diode D4 and is connected with the non-inverting input end of the operational amplifier.
The integral filter circuit is composed of a resistor R35, a resistor R31, a resistor R37, a resistor R32 and a capacitor C12. The resistor R35 and the resistor R37 are connected in series to form a voltage division circuit, and computer signals are input from the resistor R35, divided by the voltage division circuit and then applied to an integration filter circuit formed by connecting the resistor R31 and the capacitor C12 in series. In the integral filter circuit, an integral constant (a product of a resistor R31 and a capacitor C12) is determined by an alternating current component of an input signal. After the integration and filtering of the integration filter circuit, the voltage is connected to the inverting input end of the operational amplifier from the upper end of the capacitor C12 through the input resistor R32, and is compared with the reference voltage of the non-inverting input end of the operational amplifier for operation. When the integral mean value of the input signal is greater than the reference voltage, the operational amplifier outputs a low level, and when the integral mean value of the input signal is lower than the reference voltage, the operational amplifier outputs a high level.
The power amplifier is composed of resistors R29, R20, R22, R25, a preamplifier Q6 and a power tube Q4. R29 is connected with the output end of the operational amplifier and the base electrode of the pre-stage amplifying tube Q6; r20 connects the emitter of power tube Q4 to the positive power supply. Wherein, R29 is the base protection resistor of preceding stage amplifier tube Q6, and R20 is the emitter protection resistor of power tube Q4, prevents that the triode Q6 in the circuit, Q4 from the electric current that flows through too big burning out. R22 connects the 28V positive power supply to the collector of the preamplifier Q6, which is the load resistor of Q6, and at the same time, it forms the pull-up resistor of the power tube Q4, and when the preamplifier Q6 is turned off, the emitter junction of the power tube Q4 is biased at 0 voltage, so as to ensure the stable turn-off of the power tube Q4. The R25 connects the collector of the preceding stage amplifying tube Q6 and the base of the power tube Q4, the bias current circuit of the power tube Q4 is composed of R22 and R25, and when the preceding stage amplifying tube Q6 is conducted, enough base current is provided for the power tube Q4 to enable the power tube Q4 to work in a saturated conducting state.
The manual switch control circuit is composed of a protection resistor R and a signal input resistor R35'.

The pull-up potential is provided by the 5V power supply to the manual switch, and when the manual switch is closed, the divided voltage of the 5V voltage on the R37 is applied to the inverting input terminal of the operational amplifier through the integrating filter circuit, and if the divided voltage is larger than the comparison voltage applied to the non-inverting input terminal of the operational amplifier, the divided voltage causes the output voltage of the operational amplifier to be reduced to a low level, so that the 28V power supply output to the engine controller is cut off. Similarly, the engine controller 28V power supply may be shut off when the input computer signal level is higher than the comparison voltage. The parameters of the switch series resistor R35' and the computer signal series resistor R35 are properly selected, so that the power supply of an engine controller can be turned off by a manual switch and a computer signal, and manual and automatic double-path control of engine parking is realized.
