Abstract
A system and method for providing functional safety in a software defined vehicle (SDV) is disclosed. The system includes a Central Controller (CC), a plurality of Zonal Controllers (ZCs) coupled with the CC, an Emergency Controller (EC) coupled to the CC and each of the plurality of ZCs. The CC or one of the plurality of ZCs is dynamically configurable as a shadow-VSM (SVSM), based on a determination of one of a plurality of modes of the SDV. The VSM is configured to monitor the EC and the plurality of ZCs and the SVSM is configured to monitor the VSM to determine the one of the plurality of modes of the SDV.
Claims18
A system for providing functional safety of controllers in a software defined vehicle (SDV), comprising:
- a Central Controller (CC);
- a plurality of Zonal Controllers (ZCs) coupled with the CC;
- and
- an Emergency Controller (EC) coupled to the CC and each of the plurality of ZCs,
- wherein the CC or one of the plurality of ZCs is dynamically configurable as a Vehicle Safety Monitor (VSM) and one of the plurality of ZCs is dynamically configurable as a shadow-VSM (SVSM), based on a determination of one of a plurality of modes of the SDV, and
- wherein the VSM is configured to monitor the EC and the plurality of ZCs and the SVSM is configured to monitor the VSM to determine the one of the plurality of modes of the SDV.
A method for providing functional safety of controllers in a software defined vehicle (SDV), the method comprising:
- determining one of a plurality of modes of the SDV based on:
- monitoring, by a Vehicle Safety Monitor (VSM), an Emergency Controller (EC) and a plurality of Zonal Controllers (ZCs) of the SDV;
- and
- monitoring, by a Shadow-VSM (SVSM), the VSM,
- wherein the SDV comprises a Central Controller (CC),
- wherein the plurality of ZCs are coupled with the CC,
- wherein the EC is coupled to the CC and each of the plurality of ZCs, and
- wherein the CC or one of the plurality of ZCs is dynamically configurable as the VSM and one of the plurality of ZCs is dynamically configurable as the SVSM, based on the determination of the one of the plurality of modes of the SDV.
A non-transitory computer-readable medium storing computer-executable instructions for providing functional safety of controllers in a software defined vehicle (SDV), the computer-executable instructions configured for:
- dynamically configuring a Central Controller (CC) or one of a plurality of Zonal Controllers (ZCs) as a Vehicle Safety Monitor (VSM) and dynamically configuring one of the plurality of ZCs as a shadow-VSM (SVSM), based on a determination of one of a plurality of modes of the SDV;
- and
- monitoring, by the VSM, an Emergency Controller (EC) and the plurality of ZCs and monitoring, by the SVSM, monitoring the VSM to determine the one of the plurality of modes of the SDV,
- wherein the SDV comprises the CC, the plurality of ZCs coupled with the CC, and EC coupled to the CC and each of the plurality of ZCs.
