Abstract

A gateway processor of a vehicle includes a controller area network (CAN) message receiver, an Ethernet message receiver, a vehicle state monitoring and recognition unit configured to receive a signal from the CAN message receiver and the Ethernet message receiver, and a power management determination unit for each state configured to receive a signal from the vehicle state monitoring and recognition unit. The gateway processor also includes an electronic control unit (ECU) power control application execution unit configured to receive a signal from the power management determination unit for each state.

First claim

What is claimed is:

1. A gateway processor of a vehicle, comprising:
a controller area network (CAN) message receiver;
an Ethernet message receiver;
a vehicle state monitoring and recognition unit configured to receive a signal from the CAN message receiver and a signal from the Ethernet message receiver;
a power management determination unit for each state of a plurality of vehicle states, the power management determination unit configured to receive a signal from the vehicle state monitoring and recognition unit; and
an electronic control unit (ECU) power control application execution unit configured to receive a signal from the power management determination unit for each state of the plurality of vehicle states.

2. The gateway processor of the vehicle of claim 1 , further comprising a plurality of CAN ID filters configured to transmit a signal to the CAN message receiver.

3. The gateway processor of the vehicle of claim 2 , further comprising a CAN database (DB) configured to transmit a signal to the CAN message receiver and the plurality of CAN ID filters.

4. The gateway processor of the vehicle of claim 2 , further comprising a plurality of CAN transceivers configured to transmit signals to the CAN ID filters, respectively.

5. The gateway processor of the vehicle of claim 1 , further comprising an Ethernet message filter configured to transmit a signal to the Ethernet message receiver.

6. The gateway processor of the vehicle of claim 5 , further comprising an Ethernet DB configured to transmit a signal to the Ethernet message receiver and the Ethernet message filter.

7. The gateway processor of the vehicle of claim 5 , further comprising:
a plurality of Ethernet physical transceivers (PHYs) configured to transmit a signal to the Ethernet message filter; and
an Ethernet switch between the Ethernet PHYs and the Ethernet message filter.

8. A control logic method comprising:
receiving, by a gateway processor of a vehicle, at least one of a vehicle controller area network (CAN) message or a vehicle Ethernet message;
determining, by the gateway processor, whether a vehicle state analysis necessity data is present in the received message;
upon determining that the vehicle state analysis necessity data is present in the received message, executing, by the gateway processor, vehicle related determination logics, wherein the vehicle related determination logics include a surrounding environment determination logic, a driving state determination logic, and a vehicle state determination logic;
checking, by the gateway processor, power control conditions of electronic control units (ECUs); and
controlling, by the gateway processor, power of the ECUs according to the checked power control conditions.

9. The control logic method of claim 8 , wherein the surrounding environment determination logic comprises determining, by the gateway processor, daytime or nighttime.

10. The control logic method of claim 9 , further comprising controlling, by the gateway processor, power of the ECUs according to the determining.

11. The control logic method of claim 9 , wherein the determining is performed, by the gateway processor, according to a power control condition set by a user.

12. The control logic method of claim 10 , wherein the controlling power of the ECUs is one of power on, power off, or power sleep.

13. The control logic method of claim 8 , wherein the driving state determination logic comprises determining, by the gateway processor, a parking state, or a stop state.

14. The control logic method of claim 8 , wherein the vehicle state determination logic is executed when a message corresponding to vehicle state change is received.

15. A non-transitory computer readable recording medium storing a program including instructions that, when executed by a gateway processor, causes the gateway processor to:
receive at least one of a vehicle controller area network (CAN) message or a vehicle Ethernet message;
determine whether a vehicle state analysis necessity data is present in the received message;
upon determining that the vehicle state analysis necessity data is present, execute vehicle related determination logics, wherein the vehicle related determination logics include a surrounding environment determination logic, a driving state determination logic, and a vehicle state determination logic;
check power control conditions of electronic control units (ECUs); and
control power of the ECUs according to the checked power control conditions.
