## Abstract

An in-vehicle system includes: an autonomous driving system device that is mounted in a vehicle and implements autonomous driving of the vehicle; an autonomous driving controller that is configured to control the autonomous driving system device to perform a control related to the autonomous driving of the vehicle; a first network that connects the autonomous driving system device and the autonomous driving controller with a protocol conversion unit interposed therebetween so as to perform communication with each other by using a plurality of different protocols; and a second network that connects the autonomous driving system device and the autonomous driving controller without the protocol conversion unit interposed therebetween so as to perform communication with each other by using a single protocol.

## Claims

### Claim 1

An in-vehicle system comprising:
an autonomous driving system device that is mounted in a vehicle and implements autonomous driving of the vehicle;
an autonomous driving controller that is configured to control the autonomous driving system device to perform a control related to the autonomous driving of the vehicle;
a first network that connects the autonomous driving system device and the autonomous driving controller with a protocol conversion unit interposed therebetween so as to perform communication with each other by using a plurality of different protocols, the protocol conversion unit performing protocol conversion; and
a second network that connects the autonomous driving system device and the autonomous driving controller without the protocol conversion unit interposed therebetween so as to perform communication with each other by using a single protocol, wherein
the autonomous driving system device includes an autonomous driving system operation device of which an operation is controlled by the autonomous driving controller to implement the autonomous driving of the vehicle, and an autonomous driving system detection device that detects information used for the autonomous driving of the vehicle and outputs the information to the autonomous driving controller,
the first network connects the autonomous driving system operation device and the autonomous driving system detection device, and the autonomous driving controller with the protocol conversion unit interposed therebetween so as to perform communication with each other, and
the second network connects the autonomous driving system operation device and the autonomous driving system detection device, and the autonomous driving controller without the protocol conversion unit interposed therebetween so as to perform communication with each other.

### Claim 2 (depends on 1)

The in-vehicle system according to claim 1, wherein
the autonomous driving system detection device includes a plurality of detectors, and
the second network includes a detector hub that is interposed between the plurality of detectors and the autonomous driving controller in a mutually communicable manner, aggregates detection information obtained by the plurality of detectors, and transmits the detection information to the autonomous driving controller.
