step S11: and judging whether the current speed of the extended range type concrete mixer truck is greater than a preset speed threshold value or not.
In the embodiment, the stirring principle of the stirring cylinder in the stirring truck is that concrete materials are brought to a high position by the spiral blades in the stirring cylinder and fall by self weight to be stirred; the mixer truck is a special inclined tank type transport vehicle which is characterized in that concrete materials are pushed out by helical blades in a mixing drum, and the axis of the mixing drum inclines for a certain angle relative to the horizontal plane. The range-extended electric vehicle can achieve all power performances under a pure electric mode, when the vehicle-mounted rechargeable energy storage system cannot meet the requirement of the endurance mileage, the vehicle-mounted auxiliary power supply device is turned on to supply electric energy to the power system so as to prolong the endurance mileage, and the vehicle-mounted auxiliary power supply device is not in transmission connection with a driving system such as a transmission shaft (belt). It can be understood that whether the extended range type concrete mixer truck is currently in a running state can be judged by judging whether the current speed of the extended range type concrete mixer truck is greater than a preset speed threshold value.

Step S24: if so, closing the electromagnetic clutch so as to enable the engine power takeoff to work, transmitting first electric quantity generated by the operation of the engine to the upper motor, and driving the mixing drum to work by using the upper motor.
In this embodiment, as shown in a specific schematic diagram of driving a mixing drum in fig. 5, if the current speed is greater than the preset speed threshold, the extended range concrete mixer is in a driving state, and the current battery power is less than the preset battery power threshold, the first power of the engine needs to be transmitted to the upper-mounted motor to drive the upper-mounted motor to operate, so that the electromagnetic clutch can be closed, and the first power can be transmitted to the upper-mounted motor.
In this embodiment, the utilizing the upper motor to drive the mixing drum to work specifically includes: and increasing the torque of the second electric quantity by using the second electric quantity produced by the upper motor and through the speed reducer to obtain a third electric quantity meeting a first preset condition, and then driving the mixing drum to work by using the third electric quantity.

In this embodiment, as shown in a specific schematic diagram of driving a mixing drum shown in fig. 6, if the current speed is greater than the preset speed threshold, the extended-range concrete mixer is in a driving state, and the current battery power is not less than the preset battery power threshold, so that the power battery of the extended-range concrete mixer currently has surplus power, and the upper-mounted driving motor can be used to drive the mixing drum to operate.
Step S26: if not, acquiring the current battery electric quantity of a power battery in the extended-range concrete mixer truck, and judging whether the current battery electric quantity is smaller than a preset battery electric quantity threshold value; if not, the electromagnetic clutch in the preset power transmission line is disconnected, so that the power takeoff of the engine stops working, and the upper motor is used for driving the mixing drum of the extended-range concrete mixer to work.
In this embodiment, as shown in a specific schematic driving diagram of a mixing drum shown in fig. 7, a first working state of the upper motor, a second working state of the power battery, and a third working state of the upper driving motor are obtained, and a target working state meeting a second preset condition is selected from the first working state, the second working state, and the third working state; and determining a target component corresponding to the target working state from the upper motor, the power battery and the upper driving motor, so that the electromagnetic clutch is switched on based on the target component, the power takeoff of the engine works, a first electric quantity generated by the running of the engine is transmitted to the speed reducer, and the mixing drum is driven to work. It can be understood that the target working state meeting the second preset condition is the abnormal working state from the first working state, the second working state and the third working state, that is, the first working state of the upper motor, the second working state of the power battery and the third working state of the upper driving motor are monitored in real time, if the abnormal working state exists in the first working state, the second working state and the third working state, the target component corresponding to the abnormal working state is determined as a fault component, the first electric quantity generated by the operation of the engine is transmitted to the speed reducer, and the speed reducer increases the torque in the first electric quantity to drive the mixing drum to work. It should be noted that, it may also be monitored whether the fourth operating state of the motor controller is an abnormal operating state, if so, the motor controller is a faulty component, and when the electromagnetic clutch is closed, the electromagnetic clutch may be closed in a manual mode or an automatic mode.
