The traditional fuel power gradually develops towards hybrid vehicle types, pure electric vehicle types and the like. In the use process of a vehicle, as a key device for regulating the air temperature in the vehicle and the device temperature, an electric compressor is gradually replaced by a mechanical compressor so as to solve the problems of high cost, complex control and poor reliability of the electric compressor.

More specifically, the driving unit 10 is connected to the mechanical compressor 111, and the driving unit 10 provides kinetic energy to the mechanical compressor 111 to cause the mechanical compressor 111 to supply cold or heat to the temperature adjusting unit 11 to cause the temperature adjusting unit 11 to adjust the temperature of the vehicle.

Fig. 2 is a schematic structural diagram of a vehicle according to an embodiment of the present application, and as shown in fig. 2, includes a driving unit 20, a temperature adjusting unit 21, a front wheel axle 24, and a rear wheel axle 23. Wherein the drive unit 20 comprises a front drive unit 201 and a rear drive unit 202, the tempering unit 21 comprises a first tempering unit 211 for tempering a first target object and a second tempering unit 212 for tempering a second target object, the first tempering unit 211 comprises a front compressor 213, and the second tempering unit 212 comprises a rear compressor 214. The first power output end of the front driving unit 201 is mechanically connected to the front axle 24, the second power output end of the front driving unit 201 is mechanically connected to the power input end of the front compressor 213, the first power output end of the rear driving unit 202 is mechanically connected to the rear axle 23, and the second power output end of the rear driving unit 202 is mechanically connected to the power input end of the rear compressor 214.

When the vehicle is in operation, the front drive unit 201 powers the front compressor 213 from its second power output, so that the front compressor 213 operates to supply cold or heat to the first temperature adjustment unit 211. The front drive unit 201 powers the front axle 24 from its first power output in order to drive the vehicle in forward drive. Similarly, the rear drive unit 202 powers the rear compressor 214 from its second power output to operate the rear compressor 214 to provide cooling or heating for the second temperature conditioning unit 212.

Wherein the driving state includes: a forward drive state, a rear drive state, and a four drive state.

During the running of the vehicle, the control unit 36 obtains the rotation speed of the front driving unit 301 and the rotation speed of the rear driving unit 302 according to the rotation speed sensors mounted on the front driving unit 301 and the rear driving unit 302, and if the front driving unit 301 and the rear driving unit 302 both provide power, the rotation speed of the front driving unit 301 is greater than a first rotation speed threshold value and the rotation speed of the rear driving unit 302 is greater than a second rotation speed threshold value, in order to ensure that the power output by the driving unit 30 is sufficient to maintain the required power when the front axle 34 and the rear axle 33 operate, the control unit 36 controls the fourth clutch 321 to be in the disconnected state and controls the second clutch 322 to be in the disconnected state, so that the front driving unit 301 only provides power to the front axle 34 through the third clutch 351 and the rear driving unit 302 only provides power to the rear axle 33 through the first clutch 352.

During the running of the vehicle, if the vehicle speed is too low, that is, the rotation speed of the front axle 34 is lower than the third rotation speed threshold or the rotation speed of the rear axle 33 is lower than the fourth rotation speed threshold, and the cooling or heating load of the air conditioner 311 is too large, that is, the target output power of the front compressor 313 in the air conditioner 311 is greater than the first power threshold, the control unit 36 controls the third clutch 351 to be in the off state and controls the fourth clutch 321 to be in the on state, so that the front driving unit 301 only provides power for the front compressor 313 to ensure the cooling or heating effect of the air conditioner 311. At this time, the control unit 36 controls the first clutch 352 to be in the engaged state so that the rear driving unit 302 supplies power to the rear wheel axle 33 to ensure that the vehicle maintains the running state.

In the above process, if the target output power of the rear compressor 314 in the battery temperature adjustment state 312 is greater than the second power threshold, the control unit 36 generates a warning message indicating that the air conditioning load is large and the battery temperature adjustment unit load is large, controls the second clutch 322 to maintain the engaged state, and controls the first clutch 352 to be in the disengaged state. At this time, neither the front drive unit 301 nor the rear drive unit 302 of the vehicle provides power to the corresponding wheel axle, and the vehicle will gradually decrease in speed until the end of the running state or the driving force associated with running is obtained again.

Similar to the above process, during the running of the vehicle, if the vehicle speed is too low, i.e. the rotation speed of the front axle 34 is lower than the third rotation speed threshold or the rotation speed of the rear axle 33 is lower than the fourth rotation speed threshold, the cooling or heating load of the battery temperature adjusting unit 312 is too large, i.e. the target output power of the rear compressor 314 in the battery temperature adjusting unit 312 is greater than the second power threshold, the control unit 36 controls the first clutch 352 to be in the off state and controls the second clutch 322 to be in the on state, so that the rear driving unit 302 only provides power to the rear compressor 314 to ensure the cooling or heating effect of the battery temperature adjusting unit 312. At this time, the control unit 36 controls the third clutch 351 to be in the engaged state so that the front drive unit 301 supplies power to the front wheel shaft 34 to ensure that the vehicle keeps running.

In the above process, if the target output power of the front compressor 313 in the air conditioner 311 is greater than the first power threshold, the control unit 36 generates a warning message indicating that the air conditioning load is large and the battery temperature adjusting unit load is large, controls the fourth clutch 321 to be kept in the engaged state, and controls the third clutch 351 to be in the disengaged state. At this time, neither the front drive unit 301 nor the rear drive unit 302 of the vehicle provides power to the corresponding wheel axle, and the vehicle will gradually decrease in speed until the end of the running state or the driving force associated with running is obtained again.

In the technical scheme, two temperature adjusting units which are associated with an air conditioner and a battery are respectively arranged in a vehicle, a compressor is arranged in each temperature adjusting unit, each compressor obtains power through a corresponding driving unit, and a vehicle-mounted control unit controls the state of the driving unit for providing the power for the compressor and/or a wheel shaft which are correspondingly connected through controlling the states of two groups of clutches which are correspondingly connected with the two driving units according to the running state, the gear state and the temperature adjusting request of the vehicle, so that the corresponding compressor is controlled to supply cold or heat for the corresponding temperature adjusting unit by utilizing the compressor, and/or the wheel shaft is controlled to perform corresponding driving state adjustment, and more targeted temperature adjustment and follow-up adjustment of the driving state are realized.
