Definitions

  • This disclosure relates to a vehicle notification system.
  • the driving operation is performed mainly by the automated driving system. Then, when the system determines that the state of level 3 cannot be maintained under unforeseen circumstances, a request to take over driving is made so that the driver can respond appropriately. This request to take over driving must be made under all circumstances. Countermeasures such as doubling the control system have been taken.

  • ECU on the vehicle behavior side and the ECU on the notification side are separate entities, it is necessary to communicate between the ECUs. For example, in communication between a large number of ECUs, such as CAN (registered trademark), there is a high possibility that communication will be interrupted if an ECU fails, so one-to-one direct communication is ideal. However, if the number of direct communications between ECUs increases, the number of communication drivers, connectors, and wiring will increase, leading to an increase in cost and weight.
