The first operating signal includes fueling control information and an eighth data signal.

In the embodiment, the problem that the chassis engine electronic control unit EECU does not have the function of adjusting the engine speed according to the requirement of the upper-mounted output oil quantity is solved. After the refueling device is used as a top-loading part and is connected to a functional pin of the top-loading control module 1, the top-loading control module 1 processes refueling control information according to the refueling device to obtain a control strategy of an engine and a power takeoff, and outputs corresponding signals to control working modes of the engine and the power takeoff to realize automatic control, so that the multifunctional use requirement of the airplane tank-type refueling truck is met.

For example, when an airplane tank fuelling vehicle refuels an airplane, the tank fuelling vehicle can give corresponding requirements on total fuelling amount and fuelling flow rate, the upper control module 1 processes refuelling control information according to a fuelling device to obtain a control strategy of an engine and a power takeoff, an eighth data signal (constant flow fuelling) is sent to the chassis control module 3 through the refitting interface module 4, and the engine ECU enables the engine to start a high-speed pulse output working mode according to the eighth data signal and realizes that the engine runs at a constant rotating speed.

When the total refueling amount of the airplane reaches the required total refueling amount requirement or the airplane needs to temporarily quit operation, the upper control module 1 processes refueling control information according to the refueling device to obtain a control strategy of an engine and a power takeoff, an eighth data signal (a refueling stop signal) is sent to the chassis control module 3 through the refitting interface module 4, the engine ECU stops refueling according to the eighth data signal, and the power takeoff stops working according to the eighth data signal.

When an operator needs to adjust the refueling flow in the refueling process, the upper control module 1 processes the refueling control information of the refueling device to obtain a control strategy of an engine and a power takeoff, an eighth data signal (non-constant flow refueling) is sent to the chassis control module 3 through the refitting interface module 4, and the engine ECU increases or decreases the rotating speed of the engine according to the eighth data signal, so that precise and tiny rotating speed adjustment is realized, and the requirement of the required refueling flow is met.

The upper-mounted control module 1 can also realize automatic selection of proper engine speed and output of the same control signal by analyzing and calculating performance data of the upper-mounted oil pump according to a pre-stored control strategy and considering the finally selected engine speed value of the power takeoff speed ratio and the transmission efficiency of the upper-mounted oil pump. The chassis automatically adjusts the rotating speed of the engine according to the requirement of the oil delivery amount of the upper part, and automatically stops the work of the power takeoff.

The invention also provides a whole vehicle control method applied to the tank type fuelling vehicle of the airplane, which comprises the following steps:

a loading control module 1 for controlling the loading part, a chassis control module 3 for controlling the chassis part, and a retrofit interface module 4 for data processing and transmission are preset. When the vehicle is modified, the upper part is connected to the functional pin of the upper control module 1, and the upper control module 1 is connected with the chassis control module 3 and the chassis part through the CAN bus. After the vehicle is refitted, the upper mounting part sends a first operation signal to the upper mounting control module 1, the upper mounting control module 1 sends the first operation signal to the refitting interface module 4, and the refitting interface module 4 processes the first operation signal and then sends the first operation signal to the chassis control module 3 and the chassis part. The chassis control module 3 and the chassis part send a second operation signal to the refitting interface module 4, and the refitting interface module 4 processes the second operation signal and then sends the second operation signal to the loading control module 1, and sends the second operation signal to the loading part through the loading control module 1.

The present application is not limited to the above embodiments, and it will be apparent to those skilled in the art that various modifications and improvements can be made without departing from the principle of the present application, and such modifications and improvements are also considered to be within the scope of the present application.
