Description

Method, system and non-volatile computer readable medium for controlling start of internal combustion engine apparatus
Technical Field
The present application relates to a method, system, and non-transitory computer readable medium for controlling start-up of an internal combustion engine apparatus.
Background
Internal combustion engine installations are used in large numbers on off-road vehicles, in particular on fork-lift trucks. A48V power-assisted recovery system is arranged on a forklift, and a 48V starter is arranged in the power-assisted recovery system, the starter is powered by a lithium battery to work, and an internal combustion engine can be driven to start through the starter. Meanwhile, a 12V starter is also arranged on the forklift, the 12V starter is provided with a lead-acid storage battery, the battery capacity of the lead-acid storage battery is far larger than that of a lithium battery, and the lead-acid storage battery has strong starting performance.
It is well known that internal combustion engines are under conditions that vary greatly from start to start. If the engine is just shut down and needs to be restarted, for example, in an internal combustion engine with a vehicle start-stop system, the vehicle can be restarted very conveniently, and the engine can be started smoothly only by using a starter of the power recovery system. However, if the controller controlling the internal combustion engine is completely powered down, for example, if the vehicle stops for a long time, the starter of the internal combustion engine cannot be used to start the internal combustion engine again, and different vehicles may have different starting modes when the internal combustion engine is restarted in order to ensure the starting performance of the vehicles. If some vehicles use a 12V starter alone, some vehicles use both a 12V starter and a 48V starter to ensure starting.
However, the above starting methods have their disadvantages, and the use of a 12V starter alone may not be able to start normally in some cases, and the use of 12V and 48V starters may cause waste of energy.
