Problems solved by technology
[0004]
The disadvantage of the above-mentioned technology is that although the first solution can realize the power take-off from the power source of the chassis, since the speed ratio required by the transmission is different when walking and power take-off, the speed and steering of the power take-off oil pump will be limited, and it is impossible to realize the power take-off of the vehicle. Taking power while walking cannot meet the needs of special vehicles such as hook-arm trucks and tractors for power-taking walking functions
The second option, although it can realize power-taking walking, but the whole vehicle needs to add an additional set of bodywork electronic control system, which not only increases the cost, but also complicates the bodywork system and increases the risk of failure of the bodywork system

Embodiment Construction
[0029] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.
[0030] Such as figure 1 , the embodiment of the first aspect of the present invention proposes a vehicle power take-off control method. The vehicle includes a first drive axle and a second drive axle. The control method includes the following steps: judging whether a power take-off input signal is received; signal; if the power take-off input signal and the driving signal are received, the first drive axle is controlled to drive the vehicle, and the second drive axle is controlled to be used for power take-off.

The invention discloses a vehicle power take-off control method. A vehicle comprises a first driving axle and a second driving axle; the vehicle power take-off control method comprises the following steps of judging whether a power take-off input signal is received or not; and if the power take-off input signal is received, controlling the first driving axle to drive the vehicle to run to controlthe second driving axle to take off power. According to the vehicle power take-off control method disclosed by the embodiment of the invention, the processes that the first driving axle drives the vehicle to run and the second driving axle takes off power are simultaneously and independently carried out without additionally mounting a power take-off system; and therefore, the operation is simple,enough power can be provided for an upper part mechanism while the vehicle is running so that the vehicle can takes off power during running. The invention further discloses a vehicle power take-off control system.
Description
technical field [0001] The invention relates to a vehicle power take-off control method and a control system. Background technique [0002] With the improvement of the function requirements of special vehicles in today's society, different bodywork structures of special vehicles have also emerged at the historic moment, so the requirements for power sources of bodywork are also getting higher and higher. However, the current power take-off methods are either unable to drive high-power upper-mounted devices, or cannot realize power take-off while the vehicle is running. [0003] The current technology closest to the present invention is: allowing the bodywork system to take power from the chassis drive system when the vehicle is stationary, thereby realizing the work of the bodywork; or additionally adding a bodywork motor and a motor controller to drive the bodywork system, thereby realizing The vehicle takes power while walking. [0004] The disadvantage of the above-ment...
