Embodiment Construction

[0046] figure 1 is a flowchart of a driving control method according to an embodiment of the present invention. Such as figure 1 As shown, the present invention provides a driving control method for an extended-range electric vehicle, the method comprising the following steps:

[0047] S10: Collect environmental information around the vehicle.

[0048] S20: Determine whether the vehicle enters an area requiring zero emission according to the environmental information.

[0049] S30: Controlling the vehicle to switch to a pure electric drive mode when the vehicle enters an area requiring zero emission.

[0050] In this embodiment, the camera on the vehicle can be used to detect the environmental information around the vehicle, such as a signboard on the side of the road, etc., and identify whether the signboard indicates that this area is an area that requires zero emissions, such as a city that requires zero emissions Or a specific emission detection area. It may be to rec...

Abstract

The invention provides a driving control method and control system for an extended range electric vehicle, and belongs to the field of vehicles. The driving control method comprises the following steps of acquiring environmental information around a vehicle; judging whether the vehicle enters an area with the requirement of zero emission according to the environment information; and controlling the vehicle to enter a pure electric driving mode when the vehicle enters the area with the requirement of zero emission. The invention further provides a corresponding driving control system. The driving control method and control system can be applied to different environmental conditions.

Description

technical field [0001] The invention relates to the field of vehicles, in particular to a drive control method and control system for an extended-range electric vehicle. Background technique [0002] A range-extended electric vehicle is an electric vehicle that uses other energy sources (such as gasoline) to supply electric energy when the battery power is exhausted. Its main working feature is that it works in pure electric mode in most cases, and works in range-extending mode in a few cases, that is, the range-extender generates electric energy to drive the motor or charge the battery. [0003] When a vehicle enters an area that requires emissions, such as a city that requires zero emissions or a specific emission detection area, it is required that the extended-range electric vehicle can only be driven by the drive battery as the power source. However, the drive of the existing extended-range electric vehicles is mainly considered to meet the needs of the driver, so the ...
