Description
Technical Field

Background
With the rapid development of animal husbandry, the demand of pasture is increased, while wild pasture cannot meet the demand of pasture, so that the pasture planting area is increased. The harvesting time of the pasture has strict requirements, and the pasture needs to be harvested within a few days after the pasture is mature, otherwise the nutrient content of the pasture is reduced, and the price of the pasture is greatly reduced. In addition, during the period of harvesting and airing the forage grass, if it rains, the quality of the forage grass can also drop greatly. Therefore, the pasture grower needs to harvest as soon as possible in a good weather stage during the pasture maturity period, which puts high demands on the harvesting speed. In recent years, large-scale pasture harvesting machines have been put into practice. The input of the grass cutter greatly improves the harvesting speed and the quality of the grass.
At present, the power of the mower is from an engine, and the engine provides a power source for vehicle walking, working parts and other auxiliary parts. In order to ensure the mowing effect, the high-power working mode of the engine is adopted in the working state, and the high cutting speed, the high walking speed and the pressure source of the hydraulic working part can be provided in the high-power mode of the engine, so that the mowing effect can be better and faster. That is, the power output of the engine is divided into three parts and acts on the whole vehicle, namely a walking part, a working part and an auxiliary working part. The whole working effect can be ensured by adopting high-power output in the whole operation process.
Because the high-power output is always kept in the whole operation process, the oil consumption of the whole vehicle is overhigh, the exhaust emission is high, and the pollution to the environment is larger. In addition, in many cases, there is a waste of power output, for example, when the vehicle is not operated while walking, the vehicle only needs to supply power for the vehicle to walk, and when the vehicle is not operated while working, only needs to supply power for the vehicle to work. In these situations, the engine power output is wasted.

The main control logic is divided into five parts:
1. when the seat safety signal is received, the vehicle is in a forward or backward state, and the working component is in a working state, the engine can output the maximum rotating speed and the maximum torque. The rotating speed and the torque of the engine can be set through the display screen, and a user can set the required numerical value through the use effect of the user.
2. When the seat safety signal is received, the vehicle is in a forward or backward state, and the working component is in a non-working state, the engine adjusts the power output to the middle gear speed and the torque.

3. The engine regulates power output to a mid-range speed and torque when the seat safety signal is received, the vehicle is in a neutral state, and the working component is in a working state. The middle gear speed and the torque can also be set through the display screen.
4. And when the seat safety signal is not received, the power output of the engine is regulated to an idle state through time delay judgment when the driver is determined to leave the seat.
5. When the output size of the hand throttle or the foot throttle is changed, the rotating speed output of the engine can be adjusted in real time, and the rotating speed corresponding to the throttle signal is output. And when the first 4 state signal changes are received again, outputting the corresponding rotating speed and torque.
When the rotating speed and the torque of the engine are adjusted, the power output changes through the set function curve, the working requirement can be met when the power changes, the sudden change of the power of the vehicle can be avoided, and the operation comfort of a user is guaranteed.
The content of the present invention can be more conveniently understood through the flow chart in fig. 3, firstly, the seat safety signal is judged, if no signal is generated, the current transmitter is in an idle state, if a signal is generated, the throttle signal is judged, and when the throttle change is received, the engine speed is adjusted according to the calibrated proportional relation. And after the adjustment is finished, keeping the current rotating speed. Until the state change is received again, the engine speed changes again. If the throttle signal is not changed, the handle signal and the rotating speed of the cutting knife are judged at the same time, if the rotating speed of the cutting knife is greater than a set value and the handle is not in a neutral gear, the engine is adjusted to a high-grade rotating speed and the torque is adjusted to a high torque, if the rotating speed of the cutting knife is greater than the set value and the handle is in the neutral gear, the engine is adjusted to a medium-grade rotating speed and the torque is adjusted, if the rotating speed of the cutting knife is not greater than the set value and the handle is not in the neutral gear, and if the rotating speed of the cutting knife is not greater than the set value and the handle is in the neutral gear, the engine is in an idling state.
