Problems solved by technology

With the use of hybrid vehicles, the static resistance torque of the engine and the transmission characteristics of the clutch may change, and the clutch outputs a fixed torque, which may cause the engine to fail to start, so that the hybrid vehicle needs to start the engine multiple times. Leads to poor start-up drivability of hybrid vehicles

no. 1 example

[0076] refer to figure 2 , figure 2 It is the first embodiment of the method for starting the engine of the hybrid vehicle according to the present invention, and the method for starting the engine of the hybrid vehicle includes the following steps:

[0077] Step S10, obtaining the duration of the continuous starting of the engine and the torque to be output by the clutch;

[0078] In this embodiment, the hybrid vehicle includes a hybrid architecture, and the hybrid architecture includes an engine, an electric motor, and a gearbox. The engine needs to be started by the drive of the motor, and the motor is started by the torque output by the clutch.

[0079] When the hybrid vehicle just starts to start the engine, it starts timing to obtain the duration of the continuous start of the engine. When the engine is started, there is a corresponding torque output by the clutch, which is the torque to be output by the clutch. Torque can be determined based on how long the engine...

Abstract

The invention discloses a method for starting an engine of a hybrid vehicle. The method for starting an engine of a hybrid vehicle includes the following steps: obtaining the continuous starting time of the engine and the torque to be output by the clutch; and correcting the torque according to the continuous starting time to obtain target torque; controlling the clutch to output the target torque. The present invention also discloses a hybrid vehicle and a computer-readable storage medium. The present invention ensures the start-up drivability of the hybrid vehicle.

Description

technical field [0001] The present invention relates to the technical field of vehicle engines, and in particular, to a hybrid vehicle, an engine starting method, and a computer-readable storage medium. Background technique [0002] Hybrid electric vehicles have the advantages of long continuous working time of the engine, good power performance, and the advantages of no pollution and low noise of the electric motor. The above advantages make hybrid electric vehicles more and more popular. [0003] The starting of the engine is an important part of the control of the hybrid vehicle. At present, the starting of the engine is realized by the torque output by the clutch, and the torque output by the clutch is output according to a preset curve, that is, the torque output by the clutch is fixed. With the use of hybrid vehicles, the static resistance torque of the engine and the transmission characteristics of the clutch may change. The fixed torque output from the clutch may ca...
