All other embodiments, based on the embodiments in this patent, which would be within the purview of one of ordinary skill in the art without the particular effort to make the utility model are intended to be within the scope of the patent protection.

The utility model provides a hybrid power control system based on a pump truck, as shown in fig. 1 to 3, comprising: the engine 1, the motor 3, the battery 4, the gearbox 5, the clutch 6, the upper oil pump 8, the transfer case 9, the whole vehicle controller, the all-in-one power distribution module 7 and the BBM controller 12;

the engine 1, the motor 3, the gearbox 5, the clutch 6, the transfer case 9 and the upper oil pump 8 are connected in sequence; the BBM controller 12 is respectively connected with the engine 1 and the gearbox 5 through the whole vehicle controller; the whole vehicle controller is connected with the all-in-one power distribution module 7 and controls the all-in-one power distribution module 7 to operate; the battery 4 is connected with the motor 3 through the all-in-one power distribution module 7, and the battery supplies power for the motor. The battery is charged by the in-vehicle charger 2. Specifically, the in-vehicle charger 2 is connected to the battery 4 through the all-in-one power distribution module 7. The all-in-one power distribution module 7 can play a role in switching between charging and power supply. And the control is performed by the whole vehicle controller.

As an overall vehicle controller of the present utility model, an overall vehicle controller includes: an ECU controller 14, a VCU controller 16, a top-loading controller 11, an MCU controller 15, a BMS controller 10, and a TCU controller 13;

the BBM controller 12 is respectively connected with the ECU controller 14 and the TCU controller 13 through the VCU controller 16; the ECU controller 14 is connected with the engine 1; the TCU controller 13 is connected with the gearbox 5; the upper loading controller 11 is connected with the upper loading oil pump 8; the MCU controller 15 is connected with the all-in-one power distribution module 7 and controls the all-in-one power distribution module 7 to operate; the BMS controller 10 is connected with the battery 4, and the BMS controller 10 monitors the amount of electricity of the battery 4.

The power supply mode can adopt a power grid or a battery, and distributes electric energy through all-in-one power distribution to supply power for the motor; the engine is connected with the motor through a clutch, and whether the engine is intervened or not is controlled through opening and closing of the clutch; the motor is connected with the gearbox, and the transfer case is used for switching and driving the vehicle to run or driving the upper oil pump.

The power of the upper oil pump can be provided by the motor or the engine simultaneously or independently. The energy source of the motor can also be a battery or a power grid power supply, the two can simultaneously provide energy for the motor or can separately provide energy, and the power grid can also directly charge the battery.

When the transfer case of the pump truck drives the upper oil pump, the power of the upper oil pump can be provided by the motor or the engine simultaneously or separately.

When the motor of the pump truck is driven alone, the clutch is disengaged and torque is provided solely by the motor. When the engine is driven independently, the clutch is closed, torque is provided by the engine only, and the motor rotates along with the engine. When the engine and the motor are driven together, the clutch is closed, and the engine and the motor both provide torque.

The control of the upper oil pump by the hybrid pump truck requires the upper oil pump provided by the BBM controller to request the rotation speed according to the battery charge SOC provided by the BMS controller 10. The control strategy core of the hybrid pump truck system for the loading oil pump in situ mainly utilizes the commercial power as much as possible, reduces the fuel consumption and saves the energy.

The control strategy of the hybrid pump truck is as follows: and judging the rotating speed required by the BBM controller according to the required torque of the upper oil pump, and distributing the torque required to be born by the motor and the engine. When the BBM controller requests a smaller rotating speed, all torque is provided by the motor; when the required rotating speed of the BBM controller is larger, the motor torque can not maintain the rotating speed required by the upper oil pump, and the engine torque is gradually increased until the required rotating speed of the BBM controller can be maintained.

The control strategy of the hybrid pump truck is as follows: the electric energy in the battery is mainly used for driving in running. When the upper oil pump is driven in situ, the electric energy of the power grid is mainly used.

When the battery power SOC is too high, namely, the battery power SOC is more than 85%, the battery provides a part of electric energy, so that the battery power is prevented from being too high

When the battery power is too low, namely the battery power SOC is less than 30%, the power grid charges the battery while supplying power to the motor under the condition that the BBM controller requests a low rotating speed.

When the SOC value is between 30% and 85% when the electric quantity of the battery is normal, the battery does not drive the upper oil pump and is only powered by the power grid.

In order to meet the requirements of the pump truck on various environments, the characteristics of two systems of the hybrid pump truck system are fully exerted. Except that the utility power can be externally connected to a power supply for operation when the utility power is available, when the utility power is not externally connected to the power supply, the following control strategy is adopted:

when the battery is full, the motor starts to provide the working torque of the loading oil pump. The motor is powered by a battery and the engine is not operated. After the motor speed reaches the economic engine speed, the engine is started, the engine is switched to provide torque, and the motor stops working.

When the battery electric quantity is lower, only the engine is used for driving the upper oil loading pump, and only the engine consumes fuel at the moment, so that the limitation of the working place of the hybrid pump truck can be avoided.

When no external energy source is available to obtain commercial power, the engine is used for providing main power, and when the electric quantity is low, the engine is used for driving completely; when the electric quantity is higher, the motor is used for driving, and when the rotating speed of the motor is pulled to an economic action zone of the engine, the motor stops driving and is completely driven by the engine.

The hybrid power control system based on the pump truck provided by the utility model adopts a P2 structure for driving in the driving process of environmental protection and running cost saving, and adds vehicle-mounted charging piles and power grid energy sources on the basis of the P2 structure when the upper oil pump is driven in situ. Adopts the mode of using the commercial power as the main and using the fuel oil as the auxiliary. The two sets of systems operate cooperatively, so that energy conservation and low emission in the whole vehicle driving process are ensured, the loading of the oil pump by the engine under the condition of no commercial power supply is ensured, and the limitation that no commercial power cannot work is relieved. The motor and the engine are matched to improve the driving efficiency of the engine by using the motor, so that the fuel consumption is saved, and the cost is saved.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present utility model. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the utility model. Thus, the present utility model is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
