Abstract

The invention is applicable to the technical field of hybrid vehicles, and discloses an engine starting method, device, storage medium and vehicle for a hybrid vehicle, the engine starting method, and a control unit of the hybrid vehicle to obtain the starting requirement of the engine and the current vehicle state of the vehicle , the current vehicle state includes the current vehicle speed, the control unit controls the gearbox to engage the corresponding set gear according to the current vehicle speed, and the drive motor of the hybrid vehicle or / and the power at the wheel end of the vehicle is transmitted to the engine through the gearbox, so that the engine speed reaches Ignition revs and start. In the engine starting method, device, storage medium and vehicle of the hybrid vehicle provided by the present invention, the power of the drive motor or / and the wheel end of the vehicle is transmitted to the engine through the gearbox, which can replace the function of the starter and save the hardware cost of the starter.

Description

technical field [0001] The invention belongs to the field of hybrid vehicle startup, and in particular relates to an engine startup method, device, storage medium and vehicle for a hybrid vehicle. Background technique [0002] With the advancement of science and technology and the increasingly strict requirements on fuel consumption in various countries, major auto companies around the world have increased their investment in research and development of new energy vehicles. Hybrid vehicles have been paid more and more attention by various car companies because they solve the mileage anxiety problem of pure electric vehicles and at the same time reduce the fuel consumption of vehicles. The existing hybrid vehicle engine starting technology can only start the engine in reverse drag at a fixed speed range, and cannot achieve the function of reverse drag at full vehicle speed, so it cannot replace the starter. SUMMARY OF THE INVENTION [0003] The present invention aims to so...
