Document Type and Number:

WIPO Patent Application WO/2022/113747

Kind Code:

A1

Abstract:

The present invention provides an in-vehicle information processing device and an in-vehicle information processing method that can be expected to contribute to employing a multicore and shared-memory configuration in a device installed in a vehicle.　The in-vehicle information processing device according to the present embodiment includes a plurality of processing units that are installed in the vehicle and perform processing in parallel, and a plurality of shared storage units that are accessible by the plurality of processing units. The plurality of processing units perform exchange of information via at least one shared storage unit, and change the shared storage unit used for exchange of information at a predetermined timing. A detecting unit that detects abnormality of the shared storage units is provided thereto. The predetermined timing is a timing at which the detecting unit detects abnormality of the at least one shared storage units. In a case of the detecting unit detecting abnormality of the at least one shared storage units, the plurality of processing units may exchange information via a different shared storage unit.
