Claim 10:
11. A control method for a fuel-saving multi-state switch, comprising:
(1) collecting Controller Area Network (CAN) signals by a fuel-saving control unit which is connected to a vehicle body Electronic Control Unit (ECU) through a CAN bus, determining, by the fuel-saving control unit, a switch gear required by a current vehicle according to the CAN signals, and outputting, by the fuel-saving control unit, a Pulse Width Modulation (PWM) pulse signal having a corresponding duty cycle,
(2) receiving the PWM pulse signal by a PWM voltage regulating unit which is connected to the fuel-saving control unit, and outputting, by the PWM voltage regulating unit, a voltage value corresponding to the switch gear according to the PWM pulse signal, and
(3) receiving the voltage value by the vehicle body ECU which is connected to the PWM voltage regulating unit, and controlling, by the vehicle body ECU, a speed and torque of an engine according to the voltage value.
