Engine warming control method, device, equipment and terminal

Abstract

The invention discloses an engine warming control method, a device, equipment and a terminal. The method comprises the following steps of acquiring operation information of a vehicle and driver demandintention information; according to the operation information of the vehicle and the driver demand intention information, judging whether a range extender of the vehicle is started or not; if starting the range extender of the vehicle, obtaining the temperature of a cooling liquid in a cooling system of a range extender engine and the temperature of a cooling liquid in a cooling system of a drivemotor battery pack; judging whether the temperature of the cooling liquid in the cooling system of the range extender engine and the temperature of the cooling liquid in the cooling system of the drive motor battery pack meet a first preset condition or not; and if yes, starting a combined control switch to control the engine to warm. According to the method, in the engine warming process, the cooling system of the motor battery pack and the cooling system of the engine range extender are controlled in a combined mode, so that the rapid warming of the engine can be realized, emission substances generated in the heating process can be reduced, the oil consumption of engine warming can be reduced, and the warming time can be reduced.

Description

technical field [0001] The present invention relates to the technical field of engine warm-up, in particular to an engine warm-up control method, device, equipment and terminal. Background technique [0002] At present, the warm-up control method of the range extender engine of the range-extended vehicle is still completed by the independent cooling system of the engine itself, without the introduction of external heat energy; the specific transmission is through the vehicle controller (VCU) to the range extender controller (PFCU) After sending instructions, the engine controller (ECU) starts to run after receiving the start-up instruction sent by the range extender controller (PFCU); Cars are the same, without the introduction of external heat energy, the engine can only be warmed up slowly from the coolant temperature in the cold state of the engine. The warm-up process lasts for a long time, making the engine in a cold state for a long time. During this process, the engin...
