Abstract
A method and system of improving the efficiency of motor vehicles includes stopping an engine of a motor vehicle system if the motor vehicle system is immobile for more than a predetermined period of time, according to one embodiment. The method and system includes starting the engine with a magneto system, in response to one or more vehicle conditions, such as operation of a throttle, operation of a clutch, and/or operation of a brake lever, according to one embodiment.
Claims20
A system for a vehicle, comprising:
- an engine having a rotor and a magneto system operably coupled to the rotor, the magneto system including one or more inductive coils adjacent to the rotor and one or more permanent magnets attached to the rotor;
- a power management unit electrically coupled to the magneto system, the power management unit configured to receive a first voltage from the magneto system in a first operation mode of the power management unit, and configured to provide a second voltage to the inductive coils of the magneto system to rotate the rotor in a second operation mode of the power management unit;
- and
- a controller communicatively coupled to the power management unit and configured to control that the power management unit is one of in the first operation mode or in the second operation mode.

A method, comprising:
- detecting an operation state of a vehicle;
- switching an engine of the vehicle into a non-combustion state based on a detected first operation state of the vehicle, the engine including a rotor and a magneto system;
- receiving a battery voltage from a battery;
- and
- providing a first voltage based on the battery voltage to the magneto system to cause the magneto system to rotate the rotor of the engine.
