Failure management in a vehicle

Abstract

A system includes first and second failsafe devices. Each of the failsafe devices includes a processor and a memory. The memory stores instructions executable by the processor for performing at least one of detecting a fault and providing a communication concerning a fault. The system further includes an arbitration bus connecting the first and second failsafe devices. The communication concerning the fault may be provided from a first one of the first and second failsafe devices to a second one of the first and second failsafe devices.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to US Provisional Patent Application No. 62 / 023,396, entitled "Fault Management in Vehicles," filed July 11, 2014, which is hereby incorporated by reference in its entirety. Background technique [0003] Autonomous vehicles, ie, vehicles in which some or all operations normally controlled by a human driver are controlled and carried out by components in the vehicle without driver intervention, rely on maintaining and coordinating key subsystem functions in the event of failure. For example, related failures may include power failures, communication failures, and logic device failures. Failure of the powertrain, braking subsystem, steering subsystem, etc. that transmits power to the vehicle, and the resulting failure of vehicle operation, can place the vehicle driver and / or other vehicle occupants at risk. Unfortunately, there is currently a lack of mechanisms for handling power failures ...
