Abstract

A power supply system with automatic switchover voltage for vehicle control unit is proposed. The system comprises a supply communication module configured to communicate with a vehicle control unit, the supply communication module comprising a power supply module to provide power for a vehicle control unit; and a communication device coupled to the supply communication module for showing power supply status; wherein the supply communication module provides a first direct voltage and communicates with the vehicle control unit before supplying power, and if the supply communication module does not receive any message from the vehicle control unit within a first time interval, the supply communication module automatically switches to a second direct voltage from the first direct voltage or automatically increases the first direct voltage within a second time interval, and supplies power to the vehicle control unit; and wherein the second direct voltage is greater than the first direct voltage.

Claims

1. A power supply system with automatic switchover voltage for vehicle control unit at least comprising:

a supply communication module configured to communicate with a vehicle control unit of a mobile vehicle, said supply communication module comprising a power supply module to provide power for said vehicle control unit of said mobile vehicle; and

a communication device coupled to said supply communication module for showing power supply status;

wherein said supply communication module provides a first direct voltage and communicates with said vehicle control unit of said mobile vehicle before supplying power, and if said supply communication module does not receive any message from said vehicle control unit of said mobile vehicle within a first time interval, said supply communication module automatically switches to a second direct voltage from said first direct voltage or automatically increases said first direct voltage within a second time interval, and supplies power to said vehicle control unit; and

wherein said second direct voltage is greater than said first direct voltage.

2. The system of claim 1, wherein said communication device further comprises a panel for showing said power supply status and for manually selecting supply voltages of said vehicle control unit.

3. The device of claim 1, wherein said first direct voltage is 12V, and said second direct voltage is 24V.

4. The device of claim 1, wherein said communication between said supply communication module and said vehicle control unit is applied to GB national standard and controlled area network (CAN).

5. A power supply method with automatic switchover voltage for vehicle control unit comprising:

providing a first direct voltage for a vehicle control unit of a mobile vehicle by a supply communication module; and

communicating with said vehicle control unit of said mobile vehicle and confirming whether power supply functions regularly by said supply communication module;

wherein if said supply communication module does not receive any message from said vehicle control unit of said mobile vehicle within a first time interval, said supply communication module automatically switches to a second direct voltage from said first direct voltage, and wherein said second direct voltage is greater than said first direct voltage.

6. The method of claim 5, wherein if said supply communication module does not receive any message from said vehicle control unit of said mobile vehicle within a first time interval, said supply communication module automatically switches to a second direct voltage from said first direct voltage or automatically increases said first direct voltage within a second time interval, and supplies power to said vehicle control unit.

7. The method of claim 5, wherein said first direct voltage is 12V, and said second direct voltage is 24V.

8. The method of claim 5, wherein comprises using a communication device or a panel to show power supply status and manually select supply voltages of said vehicle control unit.

9. The method of claim 5, wherein said communication between said supply communication module and said vehicle control unit is applied to GB national standard and controlled area network (CAN).

10. The method of claim 6, wherein comprises automatically increasing said first direct voltage and supplying power to confirm a power demand of said mobile vehicle.
