Patent ID: 8903622

Claim:
A vehicle power generation system, wherein the vehicle comprises an engine that supplies power to the vehicle, the engine comprises a crankshaft and a vehicle transmission unit connected to and driven by the crankshaft, and the vehicle transmission unit is connected to wheels of the vehicle; wherein, the vehicle power generation system comprises: a power generation unit, including a generator, a power input shaft driving the generator to generate power, and a power output unit electrically connected to the generator; a power supply unit, connected to the power output unit, and provides a power connecting interface; a clutch mechanism, including a speed increasing unit connected to the power input shaft, and a motor controller for attaching the speed increasing unit to the crankshaft or detaching the speed increasing unit from the crankshaft; and a control unit, electrically connected to the motor controller, and includes a power generation condition determining unit for determining whether the vehicle is under a safe and stationary condition that is suitable for power generation, and then driving the clutch mechanism based on the result; wherein, after the control unit receives a power generating mode switching signal to confirm that the vehicle is under a condition suitable for power generation, the control unit drives the clutch mechanism to attach to the crankshaft of the engine, thereby allowing the crankshaft to be connected to the power input shaft of the generator, and increasing a rotation speed of the engine to a first setting rotation speed value, and then increasing the rotation speed of the engine even more to a second setting rotation speed value through the speed increasing unit, thus the generator is driven and electrical power for the power supply unit is hence generated; wherein, after the control unit receives a vehicle-moving mode switching signal, the control unit drives the clutch mechanism to detach from the crankshaft, thereby ending power generation; wherein the power generation condition determining unit determines whether the vehicle is under a safe and stationary condition suitable for power generation according to the conditions included: a wheel speed of the vehicle is 0; a gearshift of the vehicle is moved to neutral or parking position; a throttle opening of the vehicle is at an idle speed position; a handbrake lever of the vehicle is pulled up to a locked position; and a temperature of the generator is not overheated, which means that the temperature of the generator falls into a predetermined safe temperature range; the control unit comprises an alarming unit, the alarming unit may at least use corresponding audio sound or light signals to indicate whether the vehicle is in a vehicle-moving mode, a power generating mode, or an alarming mode, and the control unit receives the mode switching signal sent by a switch, wherein the mode switching signal includes the power generating mode switching signal and the vehicle-moving m switching signal.
