In-vehicle system with abnormality detection using two separate networks

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 comprising a processor that executes the autonomous driving controller to implement the autonomous driving of the vehicle, and an autonomous driving system detection device comprising a sensor that obtains detection information used for the autonomous driving of the vehicle and outputs the detection 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, wherein
• the autonomous driving system detection device outputs the detection information onto the first network and the second network, and
• the autonomous driving controller detects an abnormality of the in-vehicle system by determining whether the detection information received from a specific detector through the first network matches the detection information received from the specific detector through the second network.
