Problems solved by technology

In the existing technology, during the switching process between different modes, the motor torque fluctuates greatly. If it is not properly handled, there will be a sudden change in the torque, the impact will become larger, and the ride comfort will be reduced, which will seriously affect the comfort and safety of the driver.

Embodiment Construction

[0048] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0049] see figure 1 , this embodiment discloses a control method for a pure electric vehicle mode, which specifically includes the following steps:

[0050] Step S101: Determine the current working mode of the vehicle according to the preset working mode determination rules; the working modes include: forward mode, energy recovery mode, slope prevention mode, creep mode and steep slope prevention mode;

[0051] It should be noted that the determination rule f...

Abstract

The invention provides a switching control method and device for the working modes of a blade electric vehicle. According to preset working mode deciding rules, the current working mode of the vehicle is determined. The working modes comprise the advancing mode, the energy recycling mode, the anti-slip mode, the peristaltic mode and the abrupt slope preventing mode. Switching rules between the advancing mode and other modes are preset, so that the vehicle is switched more smoothly between the advancing mode and other modes. According to the preset switching rules, when current running parameters meet the switching conditions, the vehicle is controlled to be switched to the target working mode from the current working mode, the problem that the torque fluctuates greatly in the switching process of the advancing mode and other modes, so that a driver feels uncomfortable is solved, the smoothness of the switching process is guaranteed, and the driving experience of the driver is improved.

Description

technical field [0001] The present invention relates to the field of vehicle control, and more specifically, to a switching control method and device for operating modes of pure electric vehicles. Background technique [0002] With the increasing shortage of petroleum resources and the increasingly serious environmental pollution, pure electric vehicles with low energy consumption and low pollution have incomparable advantages over internal combustion engine vehicles. Therefore, pure electric vehicles with high efficiency, energy saving and environmental protection have become one of the development trends of the automotive industry. one. [0003] People have been deeply impressed by the driving experience of traditional fuel vehicles, especially the various humanized designs of high-end vehicles that bring people a comfortable driving experience. However, the working mechanism of pure electric vehicles is completely different from that of traditional vehicles. While pure e...
