Abstract
A starting system of an engine mounted on a vehicle includes an air reservoir; an air motor driven by compressed air supplied from the air reservoir; a battery; an electric motor driven by electric power from the battery; and an electronic control unit. The electronic control unit performs the step of controlling the air motor and/or the electric motor so that the engine is started by at least one, determined in accordance with an air pressure in the air reservoir, of an output of the air motor and an output of the electric motor.

A starting system control method for controlling a starting system of an engine mounted on a vehicle, the starting system including an air reservoir, an air motor driven by compressed air supplied from the air reservoir, a battery, an electric motor driven by electric power from the battery, and an electronic control unit,
- the method comprising the step, performed by the electronic control unit, of:
- controlling the air motor and/or the electric motor so that the engine is started by at least one, determined in accordance with an air pressure in the air reservoir, of an output of the air motor and an output of the electric motor, wherein when the air pressure in the air reservoir is equal to or greater than a predetermined threshold, the air motor is controlled so that the engine is started by the output of the air motor, and
- when the air pressure in the air reservoir is less than the predetermined threshold, the electric motor is controlled so that the engine is started by the output of the electric motor.
A starting system of an engine mounted on a vehicle, the starting system comprising:
- an air reservoir;
- an air motor driven by compressed air supplied from the air reservoir;
- a battery;
- an electric motor driven by electric power from the battery;
- and
- an electronic control unit configured to control the air motor and/or the electric motor so that the engine is started by at least one, determined in accordance with an air pressure in the air reservoir, of an output of the air motor and an output of the electric motor,
- when the air pressure in the air reservoir is equal to or greater than a predetermined threshold, the air motor is controlled so that the engine is started by the output of the air motor, and
- when the air pressure in the air reservoir is less than the predetermined threshold, the electric motor is controlled so that the engine is started by the output of the electric motor.
A starting system control method for controlling a starting system of an engine mounted on a vehicle, the starting system including an air reservoir, an air motor driven by compressed air supplied from the air reservoir, a battery, an electric motor driven by electric power from the battery, and an electronic control unit,
- the method comprising the step, performed by the electronic control unit, of:
- controlling the air motor and/or the electric motor so that the engine is started by at least one, determined in accordance with an air pressure in the air reservoir, of an output of the air motor and an output of the electric motor,
- wherein, in the step of controlling the air motor and/or the electric motor,
- when the air pressure in the air reservoir is equal to or greater than a first predetermined threshold, the air motor is controlled so that the engine is started by the output of the air motor,
- when the air pressure in the air reservoir is less than a second predetermined threshold that is lower than the first predetermined threshold, the electric motor is controlled so that the engine is started by the output of the electric motor, and
- when the air pressure in the air reservoir is less than the first predetermined threshold and equal to or greater than the second predetermined threshold, the air motor and the electric motor are controlled so that the engine is started by both the output of the air motor and the output of the electric motor.
