Optionally, the predetermined time period may be 20S, 30S, and the like, and it should be noted that the predetermined time period may be set according to an actual situation, and the embodiment of the present application is not particularly limited.
Because the clear water liquid level of the clear water tank may fluctuate, the clear water level sensor can continuously detect whether the clear water liquid level in the clear water tank is continuously lower than the set position of the clear water level sensor within a preset time period, and if the clear water liquid level is detected to be continuously lower than the clear water level sensor within the preset time period, the current water level state is determined to be a water level abnormal state, namely, the clear water tank is indicated to lack water; if the clear water level is detected to be continuously higher than or equal to the water level sensor within the preset time period, the current water level state is determined to be a normal water level state, and the clear water tank is indicated to be full of water.
In an alternative embodiment, detecting the current water level state of the tank water level of the clean water tank in the sweeper truck comprises:
step S302, detecting whether the liquid level of the clear water in the clear water tank is continuously lower than a water level threshold value within a preset time period;

Optionally, the water level threshold is a lowest water level value of the clean water tank, if the clean water level is lower than the water level threshold, it is determined that the clean water tank is short of water, and if the clean water level is higher than or equal to the water level threshold, it is determined that the clean water tank is full of water.
In the above-mentioned alternative embodiment, it may be, but is not limited to, that the water level sensor detects whether the clean water level of the clean water tank in the sweeper truck is continuously lower than the water level threshold value within a predetermined time period, and if it is detected that the clean water level is continuously lower than the water level threshold value within the predetermined time period, it is determined that the current water level state of the clean water tank is the water level abnormal state, that is, it indicates that the clean water tank is lack of water; and if the liquid level of the clean water is detected to be continuously higher than or equal to the water level threshold value in the preset time period, determining that the current water level state of the clean water tank is a normal water level state, namely indicating that the clean water tank is full of water.

The separating work mode cuts off the power transmitted by the engine to the high-pressure water pump to achieve the purpose of separating from the high-pressure water pump, and the combining work mode transmits the power transmitted by the engine to the high-pressure water pump to achieve the purpose of combining with the high-pressure water pump.
In the above optional embodiment, if it is detected that the current water level state of the clean water tank is an abnormal water level state, an alarm message may be output to prompt a target object to perform a water filling operation on the clean water tank, and at the same time, the water pump clutch is controlled to operate in a separated working mode.

In an alternative embodiment, the controlling the operation mode of the water pump clutch of the sweeper truck according to the current operation mode and the current water level state includes:
step S602, if the current operation mode is the road sweeping mode and the current water level state is the abnormal water level state, controlling the operation stop mode of the water pump clutch and controlling the low pressure water path to be closed.
In the above optional embodiment, if the current operation mode is the sweeping mode and the current water level state is the normal water level state, the low-pressure water path is controlled to be opened.

In the above optional embodiment, if the current operation mode is the sweeping mode and the current water level state is the abnormal water level state, the operation stop mode of the water pump clutch is controlled, and the low-pressure water path is controlled to be closed. Since the water pump clutch does not participate in the operation in the road sweeping mode and the current water level state is abnormal, the low pressure water path needs to be closed.
