Problems solved by technology

[0003] The driving mode determination of a strong hybrid vehicle is a very critical part of the vehicle control strategy, but the existing strong hybrid system is composed of an engine, a generator and a drive motor on the front axle. For the storage of high-voltage battery energy, the drive motor can realize the pure electric drive of the front axle under appropriate conditions. The strong hybrid vehicle with this structure has unreasonable division of drive modes, low energy utilization efficiency of the vehicle, and large energy consumption of the vehicle. Poor passability in harsh road conditions such as ice and snow and extreme road conditions
[0004] In the process of realizing the present invention, the inventors have found that the prior art has at least the following problems: the drive mode division of the strong hybrid electric vehicle in the existing structure is unreasonable, the energy utilization efficiency of the vehicle is low, the energy consumption of the whole vehicle is large, and it is slippery in ice and snow. Poor passability in bad road conditions and extreme road conditions

Embodiment Construction

[0036] In order to make the object, technical solution and advantages of the present invention clearer, the implementation manner of the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0037] Such as figure 1 and figure 2 Shown, the technical scheme of the embodiment of the present invention is:

[0038] A driving mode control method of a four-wheel drive strong hybrid vehicle, wherein the strong hybrid vehicle includes an engine and a generator arranged in parallel on the front axle, and a drive motor arranged on the rear axle, and the steps of the driving mode and the control method include:

[0039] 1) Initialization mode

[0040] The whole vehicle is in a static state, and the control unit HCU judges whether the initialization mode condition is met, and if the condition is met, the whole vehicle enters the standby mode;

[0041] 2) Pure electric drive mode

[0042] After the vehicle enters the waiting mode, ...

Abstract

The invention discloses a method for controlling drive modes of a four-wheel drive strong hybrid automobile, belonging to the field of strong hybrid automobiles. The method comprises: a strong hybrid automobile comprises an engine, an electric generator and a drive motor, wherein the engine and the electric generator are arranged on a front shaft in parallel, and the drive motor is arranged on a rear shaft; the drive modes are as follows: 1) an initialization mode, 2) a pure motor drive mode, 3) a serial hybrid drive mode and 4) a four-wheel drive mode; and when a corresponding condition is satisfied, the corresponding mode is controlled to be started. The invention has the following beneficial effects: by arranging the engine and the electric generator on the front shaft in parallel to form parallel hybrid and then arranging the drive motor on the rear shaft to form a strong hybrid system, the four-wheel drive can be realized under the ice-snow, sloppy and other atrocious road conditions or extreme road conditions, and the trafficability of the automobile is improved; and since the drive modes comprise the initialization mode, the pure motor drive mode, the serial hybrid drive mode and the four-wheel drive mode and are reasonably divided, the energy utilization efficiency of the automobile is effective improved and the energy consumption of the whole automobile is saved.

Description

technical field [0001] The invention relates to the field of strong hybrid vehicles, in particular to a driving mode control method of a four-wheel drive strong hybrid vehicle. Background technique [0002] The vehicle drive system of hybrid electric vehicles has become a key component to achieve fuel economy and low emissions. Therefore, major vehicle manufacturers are more inclined to develop more advanced strong hybrid systems, which not only have a series-parallel hybrid structure In addition, it can also realize pure electric driving under the driving conditions with sufficient battery power and low vehicle speed. [0003] The driving mode determination of a strong hybrid vehicle is a very critical part of the vehicle control strategy, but the existing strong hybrid system is composed of an engine, a generator and a drive motor on the front axle. For the storage of high-voltage battery energy, the drive motor can realize the pure electric drive of the front axle under ...
