Problems solved by technology

[0003] At present, the four-wheel drive control of tractors is mostly controlled manually by the driver judging the working conditions. There are many subjective factors, and misjudgment is likely to occur. The four-wheel drive function cannot be turned on on suitable occasions, or the four-wheel drive system is mistakenly activated under the working conditions that should not be turned on, and the advantages of the four-wheel drive system cannot be fully utilized.

[0072] Please refer to Figure 1 to Figure 3 , this embodiment provides a four-wheel drive control method applied to vehicles, including:

[0073] Step S1, obtain the four-wheel drive start signal; wherein, the four-wheel drive start signal includes vehicle skid signal, start signal, rapid acceleration signal, differential lock activation signal, brake signal, parking signal, four-wheel drive remote control signal and four-wheel drive signal. Any one of the switching signals.

[0074] Step S2, acquiring first status information of the vehicle.

[0075] Step S3, in the state of obtaining the four-wheel drive start signal, judge whether the first state information of the vehicle meets the preset four-wheel drive start condition, if the first state information of the vehicle meets the preset four-wheel drive start condition, then control the vehicle to enter the four-wheel drive model.

[0076] Step S4, when the vehicle is in the four-wheel drive mode, acquire the second state...

Abstract

The embodiment of the invention provides a four-wheel-drive control method, device and system, a vehicle and a tractor, and relates to the technical field of four-wheel-drive control. The four-wheel-drive control method comprises the steps: acquiring a four-wheel-drive starting signal and first state information of a vehicle, and after the four-wheel-drive starting signal is obtained, if the first state information of the vehicle meets a preset four-wheel-drive starting condition, controlling the vehicle to enter a four-wheel-drive mode. The control method is simple, the automation degree and the intelligent degree are high, and unmanned four-wheel-drive automatic control can be achieved. According to the four-wheel-drive control device, the four-wheel-drive control system, the vehicle and the tractor, full-unmanned automatic operation can be achieved, the four-wheel-drive mode is started in good time, and therefore the operation efficiency is improved.

Description

technical field [0001] The present invention relates to the technical field of four-wheel drive control, in particular, to a four-wheel drive control method, device, system, vehicle and tractor. Background technique [0002] Four-wheel drive tractors are widely used. Due to the complex operating conditions of tractors, four-wheel four-wheel drive technology is adopted to enable all four wheels of the tractor to have driving capabilities, increase the driving adhesion of the vehicle, and improve operating efficiency. [0003] At present, the four-wheel drive control of tractors is mostly controlled manually by the driver judging the working conditions. There are many subjective factors, and misjudgment is likely to occur. The four-wheel drive function cannot be turned on on suitable occasions, or the four-wheel drive system is mistakenly activated under working conditions that should not be turned on, and the advantages of the four-wheel drive system cannot be fully utilized....
