Abstract

The invention discloses an engine starting method, a vehicle and a readable storage medium. The method comprises the following steps that an instruction issued by a user is received; whether an engine needs to be started or not is judged according to the starting instruction; or the state of the vehicle is obtained, and whether the engine needs to be started or not is judged according to the state of the vehicle; if a judgment result is that the engine needs to be started, vehicle operation parameters are obtained; whether the engine meets a low-pressure starting condition or not is judged according to the vehicle operation parameters; and if the engine meets the low-pressure starting condition, the engine is started in a low-pressure starting mode. By adopting the engine starting method, the vehicle and the readable storage medium, the situation that the engine cannot be started in the low-temperature environment can be avoided.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to an engine starting method, a vehicle and a readable storage medium. Background technique [0002] With the rapid development of new energy vehicles, the types and quantities of hybrid vehicles are also increasing. Generally, there are two sources of driving force for a hybrid vehicle: one is a drive motor powered by a power battery, and the other is an engine powered by fuel. Among them, the starting process of the engine also requires the power battery to provide energy. In a low temperature environment, due to the small discharge power of the battery, it cannot provide enough power to enable the motor to start the engine, which may cause the engine to fail to start successfully. Contents of the invention [0003] The invention provides a method for starting an engine, aiming at solving the technical problem that the automobile engine may fail to start successful...
