Abstract

Proposed is a method for controlling a vehicle through a multi System on Chip (SoC) system. Specifically, proposed is a method for controlling a vehicle, the method comprising the steps of: by means of a first SoC, requesting information to a second SoC or an Adaptive Driver Assistant System (ADAS); by means of the first SoC, receiving the information from the second SoC or the ADAS as a response to the request; by means of the first SoC, determining whether a vehicle is safe or not by using the received information; and by means of the first SoC, transmitting a command generated on the basis of the determination to the second SoC or the ADAS.

First claim

What is claimed is:

1 . A method of controlling a vehicle in a multi-system-on-chip (multi-SoC) system, the method comprising:
requesting information to a second SoC or an advanced driver assistance system (ADAS) by a first SoC; receiving the information from the second SoC or the ADAS in response to the request, by the first SoC; determining whether the vehicle is safe based on the received information by the first SoC; and transmitting a command generated based on the determination to the second SoC or the ADAS by the first SoC.

2 . The method according to claim 1 , wherein the first SoC and the second SoC are connected to each other through peripheral component interconnect express (PCIe), and the first SoC and the ADAS are connected to each other through a control area network (CAN).

3 . The method according to claim 1 , wherein a data packet used for the information request and reception includes command, payload length, number of elements, data payload, and end character, and
wherein the size of the data payload varies according to a data type related to the requested and received information.

4 . The method according to claim 1 , wherein when the first SoC fails to receive the information for a specific time or longer from the second SoC or the ADAS, the first SoC transmits a message indicating that the request of the information is valid to the second SoC or the ADAS.

5 . The method according to claim 1 , wherein when determining that the safety of the vehicle is at or below a specific level, the first SoC transmits, to the second SoC, a message indicating that the safety of the vehicle is at or below the specific level, and the second SoC outputs the received message on a display device connected to the second SoC.

6 . The method according to claim 1 , further comprising:
detecting that the vehicle is disconnected from a network by the second SoC; requesting information about a position, speed, and driving lane of the vehicle to the first SoC by the second SoC; and receiving the information about the position, speed, and driving lane of the vehicle from the first SoC in response to the request by the second SoC.

7 . A multi-system-on-chip (multi-SoC) system for controlling a vehicle, comprising:
a first SoC; a second SOC; and an advanced driver assistance system (ADAS), wherein the first SoC requests information to the second SoC or the ADAS, receives the information from the second SoC or the ADAS in response to the request, determines whether the vehicle is safe based on the received information, and transmits a command generated based on the determination to the second SoC or the ADAS.

8 . The multi-SoC system according to claim 7 , wherein the first SoC and the second SoC are connected to each other through peripheral component interconnect express (PCIe), and the first SoC and the ADAS are connected to each other through a control area network (CAN).

9 . The multi-SoC system according to claim 7 , wherein a data packet used for the information request and reception includes command, payload length, number of elements, data payload, and end character, and
wherein the size of the data payload varies according to a data type related to the requested and received information.

10 . The multi-SoC system claim 7 , wherein when the first SoC fails to receive the information for a specific time or longer from the second SoC or the ADAS, the first SoC transmits a message indicating that the request of the information is valid to the second SoC or the ADAS.

11 . The multi-SoC system according to claim 7 , wherein when the safety of the vehicle is determined at or below a specific level, the first SoC transmits, to the second SoC, a message indicating that the safety of the vehicle is determined at or below the specific level, and the second SoC outputs the received message on a display device connected to the second SoC.

12 . The multi-SoC system according to claim 7 , wherein the second SoC detects that the vehicle is disconnected from a network, requests information about a position, speed, and driving lane of the vehicle to the first SoC, and receives the information about the position, speed, and driving lane of the vehicle from the first SoC in response to the request.
