Embodiment 1

[0045] figure 1 It is a flow chart of a dual-motor vehicle engine control method provided by Embodiment 1 of the present invention. This embodiment is applicable to the situation of controlling the start and stop of the engine while the dual-motor vehicle is running. The method can be implemented by the dual-motor vehicle engine control device. For execution, the device may be implemented by software and / or hardware.

[0046] Such as figure 1 As shown, the method specifically includes the following steps:

[0047] Step 110, when the operating state change signal is detected, determine the engine operation mode according to the operating state change signal.

[0048] Wherein, the running state change signal can be understood as a trigger signal that needs to change the current state of the engine. The engine operating mode can be understood as a working mode that requires the engine to run. For example, the driver starts the vehicle with the vehicle key. When the key rotate...

Embodiment 2

[0102] The engine control device for a dual-motor vehicle provided in an embodiment of the present invention can execute the engine control method for a dual-motor vehicle provided in any embodiment of the present invention, and has corresponding functional modules and beneficial effects for executing the method. image 3 It is a structural block diagram of a dual-motor vehicle engine control device provided in Embodiment 2 of the present invention, as shown in image 3 As shown, the device includes: an operation mode determination module 310 , a working motor determination module 320 and an engine operation module 330 .

[0103] The operation mode determination module 310 is configured to determine the engine operation mode according to the operation state change signal when the operation state change signal is detected.

[0104] The working motor determination module 320 is configured to determine the working motor corresponding to the engine operation mode when the current ...

Embodiment 3

[0128] Figure 4 A structural block diagram of a vehicle provided in Embodiment 3 of the present invention, such as Figure 4 As shown, the vehicle includes a processor 410, a memory 420, two motors 430 and an engine 440; the number of processors 410 in the vehicle can be one or more, Figure 4 Take a processor 410 as an example; the processor 410, memory 420, input device 430 and output device 440 in the vehicle can be connected by bus or other methods, Figure 4 Take connection via bus as an example.

[0129] The memory 420, as a computer-readable storage medium, can be used to store software programs, computer-executable programs and modules, such as program instructions / modules corresponding to the dual-motor vehicle engine control method in the embodiment of the present invention (for example, dual-motor vehicle engine The operation mode determination module 310, the working motor determination module 320 and the engine operation module 330) in the control device. The ...

Abstract

The invention discloses a method, a device, a vehicle and a storage medium for controlling the engine of a dual-motor vehicle. The method includes: when an operating state change signal is detected, determining an engine operation mode according to the operating state change signal; Motor; the operation of the engine is controlled by the working motor. The present invention selects the most suitable motor among the two motors of the dual-motor vehicle to work at the current moment through the obtained operating state change signal and the actual acquisition of the current state of the vehicle, thereby effectively controlling the start and stop of the engine and solving the problem of dual-motor hybrid The problem that the engine is difficult to start and stop under different working conditions of the vehicle has achieved the effect of accurately controlling the engine start and stop, and improved the drivability, comfort and economy of the vehicle.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of vehicle design, and in particular to a method and device for controlling an engine of a dual-motor vehicle, a vehicle and a storage medium. Background technique [0002] Compared with traditional vehicles, hybrid vehicles have added motors and power batteries. During the process of starting and stopping the engine, the starter can be used, and the starting and stopping function of the engine can be realized by using the battery and the motor. However, the existing dual-motor vehicle can only start and stop the generator by specifying the motor to control the generator under specific working conditions. When the motor breaks down, the engine start-stop function cannot be realized, resulting in failure of the vehicle to drive. Therefore, how to coordinate the operation of the dual motor system and reasonably control the start and stop of the engine is the key problem to be solved a...
