Method for controlling vehicle through multi SoC system
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.
1. A method of controlling a vehicle in a multi-system-on-chip (multi-SoC) system, the method comprising:
requesting, by a first SoC, information to a second SoC or an advanced driver assistance system (ADAS);
receiving, by the first SoC, the information from the second SoC or the ADAS in response to the request;
determining, by the first SoC, whether a safety level of the vehicle is at or below a specific level based on the received information;
transmitting, to the second SoC or the ADAS, a command generated based on the determination by the first SoC;
detecting, by the second SoC, that the vehicle is disconnected from a network;
requesting, to the first SoC, information regarding a position, speed, and a driving lane of the vehicle by the second SoC; and
receiving, from the first SoC, the information regarding the position, the speed, and the driving lane of the vehicle in response to the request by the second 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 a size of the data payload varies according to a type of each data field being string or non-string, the type being related to the requested and received information.
4. The method according to claim 1 , wherein, based on failure of the first SoC to receive the information for a specific time or longer from the second SoC or the ADAS, the first SoC is configured to transmit, to the second SoC or the ADAS, a message indicating that the request of the information is valid.
5. The method according to claim 1 , wherein, based on a determination that the safety level of the vehicle is at or below the specific level, the first SoC is configured to transmit, to the second SoC, a message indicating that the safety level of the vehicle is at or below the specific level, and the second SoC is configured to output the received message on a display device connected to the second SoC.
6. 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 is configured to:
request information to the second SoC or the ADAS,
receive the information from the second SoC or the ADAS in response to the request,
determine whether a safety level of the vehicle is at or below a specific level based on the received information, and
transmit, to the second SoC or the ADAS, a command generated based on the determination, and
wherein the second SoC is configured to:
detect that the vehicle is disconnected from a network,
request, to the first SoC, information regarding a position, speed, and a driving lane of the vehicle, and
receive, from the first SoC, the information regarding the position, the speed, and the driving lane of the vehicle in response to the request by the second SoC.
7. The multi-SoC system according to claim 6 , 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).
8. The multi-SoC system according to claim 6 , 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 a size of the data payload varies according to a type of each data being string or non-string, the type being related to the requested and received information.
9. The multi-SoC system claim 6 , wherein, based on failure of the first SoC to receive the information for a specific time or longer from the second SoC or the ADAS, the first SoC is configured to transmit, to the second SoC or the ADAS, a message indicating that the request of the information is valid.
10. The multi-SoC system according to claim 6 , wherein, based on a determination that the safety level of the vehicle is at or below the specific level, the first SoC is configured to transmit, to the second SoC, a message indicating that the safety level of the vehicle is at or below the specific level, and the second SoC is configured to output the received message on a display device connected to the second SoC.
