Problems solved by technology

[0003] Nowadays, electric vehicles are gradually replacing traditional energy vehicles, but the battery life of electric vehicles is insufficient compared with traditional vehicles. The emergence of range extenders makes up for the lack of battery life. With the development of science and technology, there are many driving modes in cars , but the control method of the range extender can only satisfy the traditional driving mode, and cannot satisfy various driving modes. In different driving modes, the control method of the range extender is different, which can save electric energy and increase the battery life.

Embodiment 1

[0047] Embodiment 1 provides a method and device for controlling the starting mode of a range extender.

[0048] Such as figure 1 As shown, the start mode control method of the range extender includes the following steps:

[0049] S101. When the gear of the vehicle is the driving gear, select the driving mode as one of multiple preparatory driving modes, the preparatory driving modes at least including: intelligent driving mode, sports driving mode, energy-saving driving mode and pure electric driving mode;

[0050] S102. According to the driving mode, obtain the remaining power of the power battery pack corresponding to the driving mode;

[0051] S103. According to the driving mode and the corresponding remaining power of the power battery pack, determine whether the range extender executes the start request issued by the vehicle controller.

[0052] Specifically, when the driving mode is an intelligent driving mode, according to the driving mode and the corresponding remai...

Embodiment 2

[0103] The second embodiment provides a method and device for controlling the startup mode of the range extender.

[0104] Such as figure 2 As shown, the start-up mode control method of the range extender includes the following steps:

[0105] S201. When the gear of the vehicle is the driving gear, select the driving mode as the smart driving mode;

[0106] S202. Acquire the remaining power of the power battery pack corresponding to the driving mode according to the driving mode;

[0107] S203. According to the driving mode and the remaining power of the corresponding power battery, determine whether the remaining power of the corresponding power battery is less than a first preset power value;

[0108] S204. When the remaining power of the corresponding power battery pack is less than the first preset power value, the vehicle controller sends a starting request, and the range extender executes the starting request;

[0109] S205. When the remaining power of the correspond...

Embodiment 3

[0120] The third embodiment provides a method and device for controlling the startup mode of the range extender.

[0121] Such as image 3 As shown, the start-up mode control method of the range extender includes the following steps:

[0122] S301. When the gear of the vehicle is the driving gear, select the driving mode as the sports driving mode;

[0123] S302. Acquire the remaining power of the power battery pack corresponding to the driving mode according to the driving mode;

[0124] S303. According to the driving mode and the remaining power of the corresponding power battery, determine whether the remaining power of the corresponding power battery is less than a second preset power value;

[0125] S304. When the remaining power of the corresponding power battery pack is less than the second preset power value, the vehicle controller controls the range extender to start;

[0126] S305. When the remaining power of the corresponding power battery pack is not less than t...

Abstract

The present invention relates to the technical field of range extender control, in particular to a start-up mode control method and device for a range extender. The method includes: when the vehicle gear is in driving gear, selecting the driving mode as one of the various preparatory driving modes One of the above, the preparatory driving mode includes: intelligent driving mode, sports driving mode, energy-saving driving mode and pure electric driving mode; according to the driving mode, the remaining power of the power battery pack corresponding to the driving mode is obtained; according to the driving mode Based on the remaining power of the corresponding power battery pack, it is determined whether the range extender executes the start request issued by the vehicle controller. The present invention can determine the starting mode of the range extender in four driving modes, combined with the remaining power of the power battery pack, realizes the control of the range extender in different driving modes, ensures the use efficiency of the range extender, saves electric energy, and improves battery life .

Description

technical field [0001] The present invention relates to the technical field of range extender control, in particular to a method and device for controlling a starting mode of a range extender. Background technique [0002] With the depletion of traditional energy, the research and development of new energy is imminent, especially in the automotive industry. New energy vehicles are the main research hotspots of major automobile manufacturers, and the research and development and production of electric vehicles are particularly important. [0003] Nowadays, electric vehicles are gradually replacing traditional energy vehicles, but the battery life of electric vehicles is insufficient compared with traditional vehicles. The emergence of range extenders makes up for the lack of battery life. With the development of science and technology, there are many driving modes in cars , but the control method of the range extender can only satisfy the traditional driving mode, and cannot ...
