SAFETY MITIGATIONS FOR HOSTING A SAFETY CRITICAL APPLICATION ON AN UNCONTROLLED DATA PROCESSING DEVICE

摘要

Methods and systems for validating safety critical applications (SCAs) on uncontrolled data processing devices (UDPDs) are provided. Various combinations of checks including validation of safety critical features, validation of SCA-UDPD compatibility, and resource management are executed at various times to ensure the SCA operates properly on the device. The operation of the SCA on the UDPD may be controlled accordingly.

主权项

1. A method for hosting a safety critical application on an uncontrolled data processing device, the method comprising:
transmitting reference data from an on-body unit (OBU) to an uncontrolled data processing device (UDPD), wherein the UDPD comprises a processor, a non-transitory computer readable medium, and a safety critical application (SCA) installed on the non-transitory computer readable medium that causes the processor to:
calculate a value based on the reference data; andcompare the calculated value with a reference value; preventing the SCA from operating freely when the calculated value is different from the reference value; and permitting the SCA to operate freely when the calculated value matches the reference value.
