Embodiment 1
[0029] figure 1 It is a flow chart of a vehicle control method provided in Embodiment 1 of the present invention. This method is applicable to the situation where the vehicle is out of trouble in 2WD mode. The method can be executed by the vehicle control device. The device can be controlled by software and / or hardware Realized, and can be integrated in electronic equipment. Such as figure 1 As shown, the vehicle control method in this embodiment includes the following steps:
[0030] At present, in the 2WD mode of most vehicles, the transfer case does not transmit torque, and the vehicle runs in pure rear drive mode, which is beneficial to save fuel consumption. However, in this mode, the vehicle can only drive in pure two-wheel drive mode. If the coefficient is relatively low, it is easy to slip, the vehicle is trapped, and the four-wheel drive ability cannot be well exerted. At this time, only by manually changing the mode and switching to the AWD / 4WD mode can the vehicl...
Embodiment 2
[0039] figure 2 It is a flow chart of another vehicle control method provided in Embodiment 2 of the present application. The embodiments of the present invention further optimize the foregoing embodiments on the basis of the foregoing embodiments, and the embodiments of the present invention may be combined with various optional solutions in the foregoing one or more embodiments. Such as figure 2 As shown, the vehicle control method provided in the embodiment of the present invention may include the following steps:
[0040] S210. When the vehicle is in the 2WD mode, determine the rotational speed difference between the front and rear axles of the vehicle according to the vehicle state information.
[0041] S220. If the rotational speed difference between the front and rear axles is greater than a preset rotational speed difference threshold, calculate the closed-loop torque of the clutch according to the rotational speed difference between the front and rear axles.

Embodiment 3
[0053] Figure 4 It is a schematic structural diagram of a vehicle control device provided in Embodiment 3 of the present invention. The device is applicable to the situation that the vehicle is in 2WD mode for getting out of trouble, the device can be realized by software and / or hardware, and integrated in the electronic equipment. The device is used to implement the vehicle control method provided in the above embodiments. Such as Figure 4 As shown, the vehicle control device provided in this embodiment includes:
[0054] The speed difference determination module 410 is used to determine the front and rear axle speed difference of the vehicle according to the vehicle state information when the vehicle is in the 2WD mode;
[0055] The clutch control module 420 is configured to perform torque closed-loop control on the clutch of the vehicle according to the front-rear axle speed difference, so as to reduce the front-rear axle speed difference of the vehicle;
[0056] The ...
