Before introducing the vehicle starting method, device, storage medium, system and diesel vehicle provided by the present disclosure, an application scenario of the present disclosure is first introduced.

To how to avoid the diesel vehicle to start failure under the plateau operating mode, promote user's experience with the car, relevant technology is when the diesel engine output power of diesel vehicle is not enough, and generator helping hand electricity generation through on the diesel vehicle supplements some power for the diesel vehicle to make the vehicle start smoothly.

However, the inventor finds that when the vehicle is in a highland environment and the electric quantity of the power battery is too low, the combustion of the engine is insufficient due to the influence of atmospheric pressure, so that the engine is required to provide mechanical energy for the generator to generate electricity, the driving provided by the engine is insufficient, the diesel vehicle fails to start, and the vehicle using experience of a user is reduced.

In order to solve the technical problem, the present disclosure provides a vehicle starting method, where the vehicle may include a power battery and a low-voltage battery. Taking the method applied to a hybrid diesel vehicle as an example, fig. 1 is a flowchart illustrating a vehicle starting method according to an exemplary embodiment, and as shown in fig. 1, the method includes the following steps.

in step S140, when the electric quantity of the power battery is smaller than the electric quantity threshold, a low-voltage battery is activated to supply power to a low-voltage load on the vehicle, and an engine of the vehicle is controlled to drive the vehicle to start.

Specifically, when the power battery is too low in electric quantity, the power battery can not provide electric energy any more, the power battery is prevented from being burnt out, the power battery needs to be charged, and at the moment, the low-voltage load on the vehicle is supplied with power through the low-voltage storage battery.

Wherein the power battery of the vehicle comprises a 48V power battery, the low-voltage battery comprises a 12V battery, and the charge threshold may be a percentage of the total charge of the power battery of the vehicle, which is not specifically limited in this disclosure.

Specifically, the low-voltage load on the vehicle includes loads other than the power system on the vehicle, such as vehicle lights, air conditioners, and the like.

According to the vehicle starting method, under the condition that the vehicle is in the plateau working condition and the vehicle has the starting request, the electric quantity state of the vehicle power battery is judged, under the condition that the electric quantity state of the power battery is too low, the low-voltage storage battery is used for supplying power for the low-voltage load on the vehicle, the vehicle is only driven by controlling the engine, starting of the vehicle under the condition that the electric quantity of the power battery is too low in the plateau working condition can be completed, and the vehicle using experience of a user in the plateau environment is improved.
