Further, the engine controller 01 is further configured to obtain an engine speed, determine an engine target torque based on the engine power and the engine speed, that is, an engine torque requirement in fig. 4, and adjust a current torque of the engine according to the engine target torque, which may be understood as adjusting an original required power of the engine according to the engine torque requirement in fig. 4. In specific implementation, the air intake amount, the oil injection amount, the ignition time, the output torque and the like of the engine 03 can be controlled according to the engine torque demand.

On the other hand, the engine controller 01 is further configured to determine a generator voltage level of the vehicle-mounted generator 06 according to the water dispenser required power through a preset relation mapping table (water dispenser required power-generator voltage level), and adjust a current generator voltage of the vehicle-mounted generator 06 based on the generator voltage level, where the generator voltage level includes a primary voltage (V1), a secondary voltage (V2), and a tertiary voltage (V3), where V1 is greater than V2 and less than V3, and if the water dispenser required power is zero, the generator voltage level is set to be the primary voltage; when the required power of the water dispenser is not zero and the current heating temperature does not reach the target heating temperature, setting the voltage grade of the generator as a secondary voltage; and when the required power of the water dispenser is not zero and the current heating temperature reaches the target heating temperature, setting the voltage grade of the generator to be three-level voltage.

Further, the engine controller 01 is further configured to send a generator state instruction to the water dispenser controller 02 according to the current voltage of the generator, and then control the operating state of the electric water pump 10 according to the generator state instruction, for example, when it is detected that the water dispenser is in the "operating" state and the required power of the water dispenser is zero, set the current voltage of the generator of the vehicle-mounted generator 06 to be V1, and send a "generator state qualified" instruction in the generator state instruction to the water dispenser controller 02; when the required power of the water dispenser is not zero, regulating the current voltage of the generator to be V2, and controlling the electric water pump 10 to start; when a water outlet instruction input by a user is received and the current heating temperature reaches the target heating temperature, the current voltage of the generator can be adjusted to be V3, and the current torque of the engine can be adjusted according to the target torque of the engine, namely the original required power of the engine can be adjusted according to the torque requirement of the engine in the graph of FIG. 4. Therefore, in the embodiment, the power requirement of the water dispenser is associated with the power requirement of the vehicle and the voltage level of the whole vehicle, so that different voltage levels of the generator are set, the output power of the engine is controlled according to the heating power requirement of the water dispenser, the heater of the water dispenser starts to preheat when the water dispenser is started, the time for supplying hot water is shortened, and the voltage level of the whole vehicle is controlled to be at a high level when the power requirement of the water dispenser is larger, so that the voltage of the whole vehicle is increased to a maximum value within a working range, the time for providing a high-power vehicle-mounted power supply is further shortened, and the high-power requirement when the instant heating function of the vehicle-mounted water dispenser is realized is met.

In addition, the electric energy loss can be reduced by reducing the diameter of a wire connected between the water dispenser and a power supply.

The water dispenser controller 02 is further configured to determine whether a water outlet instruction input by a user is detected when the adjustment completion instruction is detected, determine whether the current heating temperature of the water dispenser heater 02 reaches the target heating temperature when the water outlet instruction is detected, and control the water outlet of the water dispenser to output heated drinking water when the current heating temperature reaches the target heating temperature.
