[0035] like Figure 1 As shown, this utility model application provides a drive device for controlling multi-load operation, including a microprocessor MCU, a first transceiver 10 connected to the microprocessor MCU, and a drive module 20.

[0036] Further, the driving device for controlling multiple loads is used to control the driving module 20 to drive the multiple loads to operate. In this embodiment, the driving device for controlling multiple loads is applied to the lighting system of the automobile, and the driving module 20 is used to drive the left light, the right light and the middle through light of the rear combination lamp of the automobile to operate simultaneously in the case that the automobile body provides only one network node of the rear combination lamp through the first transceiver 10 and the microprocessor MCU, so that the microprocessor MCU is used to control the normal operation of the left light, the right light and the middle through light of the rear combination lamp of the automobile, and the waste of the CAN communication network resource of the automobile is avoided.

[0037] In the embodiment of the application, the first transceiver 10 is used to be connected with the body controller 30, and the first transceiver 10 is used to receive the first signal sent by the body controller 30.

[0038] Further, the first transceiver 10 can be selected as an SBC transceiver or a CAN transceiver. In this embodiment, the first transceiver 10 receives the first signal sent by the body controller 30 through the CAN_BUS protocol and sends the received first signal to the microprocessor MCU.

[0039] In the embodiment of the application, the microprocessor MCU is used to be connected with the first transceiver 10, and the microprocessor 10 is used to receive the first signal and output the second signal according to the first signal.

[0040] Further, the microprocessor MCU outputs the second signal according to the first signal and transmits the second signal to the driving module 20. In this embodiment, if the driving device for controlling multiple loads is applied to the light control system of the automobile, the microprocessor MCU can be used as a CAN network node, and only one CAN network node is needed in the automobile network to realize the control of the entire rear combination lamp of the automobile.

[0041] In the embodiment of the application, the driving module 20 is used to be connected with the microprocessor MCU, and the driving module MCU is also connected with the multiple loads 40.

[0042] Further, if the driving device for controlling multiple loads is applied to the car light control system, the load 40 can be the rear combination lamp (such as the left rear combination lamp, the right rear combination lamp or the middle through lamp), so that the driving device for controlling multiple loads controls the simultaneous operation of multiple loads 40 through a microprocessor MCU, and the car rear combination lamp has three (or more) independent lamp bodies, but only one microprocessor MCU is needed in the car light control system, and the left rear combination lamp, the right rear combination lamp and the middle through lamp do not need to be placed with a microprocessor MCU, which can greatly save the cost of the car light control system.

[0043] One embodiment of the present application provides a driving device for controlling multiple loads, which comprises a microprocessor, a first transceiver and a driving module connected to the microprocessor, so as to control the simultaneous operation of multiple loads through a microprocessor MCU. The car rear combination lamp has three (or more) independent lamp bodies, but only one microprocessor MCU is needed in the car light control system, and the left rear combination lamp, the right rear combination lamp and the middle through lamp do not need to be placed with a microprocessor MCU, which can greatly save the cost of the car light control system, avoid the waste of car CAN communication network resources, and solve the problem that the existing car CAN communication network is controlled by multiple network nodes to control the lighting operation of the left lamp, the right lamp and the middle through lamp of the car rear combination lamp, resulting in the waste of car CAN communication network resources.

[0044] Figure 2 The driving device for controlling multiple loads provided by one embodiment of the present application is shown in the circuit diagram.

[0045] As shown in Figure 2 In one embodiment of the present application, the driving module 20 comprises a transceiver connected to each load 40.

[0046] Further, if the driving module 20 is connected with three loads 40, the corresponding driving module 20 comprises a second transceiver 21, a third transceiver 22 and a fourth transceiver 23 connected with the three loads 40 respectively; the three loads are a first load 41, a second load 42 and a third load 43 respectively, the second transceiver 21 is connected with the first load 41 by CAN bus protocol, the third transceiver 22 is connected with the second load 42 by CAN bus protocol, and the fourth transceiver 23 is connected with the third load 43 by CAN bus protocol.

The second transceiver 21, the third transceiver 22 and the fourth transceiver 23 can all be CAN transceivers. If the microprocessor MCU is placed in the middle through lamp of the rear combination lamp of the automobile, when the microprocessor MCU receives the first signal CAN_BUS(CANFD) of the body controller 30, the microprocessor MCU controls the lighting of itself (such as the middle through lamp) by outputting the second signal CAN_UART, and simultaneously controls the lighting of the left rear combination lamp and the right rear combination lamp according to the second signal CAN_UART.

[0050] Embodiment two:

[0051] The application provides a car lamp control system of an automobile, which comprises the above-mentioned driving device for controlling multiple loads to operate.

[0052] It is further illustrated that the content of the driving device for controlling multiple loads to operate has been described in Embodiment One, and the content of the driving device for controlling multiple loads to operate is not repeated in this embodiment. The car light control system can realize that a microprocessor controls multiple loads to operate simultaneously through the driving device for controlling multiple loads to operate, which can greatly save the cost of the car light control system. For example, if the driving device for controlling multiple loads to operate is applied to the car light control system, the load 40 can be the rear combination lamp (such as the left rear combination lamp, the right rear combination lamp, or the middle through lamp) of the car, so that the driving device for controlling multiple loads to operate controls multiple loads 40 to operate simultaneously through a microprocessor MCU. Since the rear combination lamp has three (or more) independent lamp bodies, only one microprocessor MCU needs to be placed in the rear lamp control of the car light control system, and the left rear combination lamp, the right rear combination lamp, and the middle through lamp do not need to be placed with a microprocessor MCU, which can greatly save the cost of the car light control system.
