A vehicle control system includes a plurality of slave ECUs, and a core ECU including a gateway function for relaying data communication among the plurality of slave ECUs and between the plurality of slave ECUs and an external apparatus. The vehicle control system accepts operation requests from a plurality of systems that makes a request for an operation to an operating unit equipped in a vehicle and performing an operation based on an operation request. The operation requests from the plurality of systems include at least a request from the external apparatus or a request from a function added to the core ECU by the external apparatus. When operation requests from the plurality of systems are accepted, the core ECU performs arbitration for the operation requests from the plurality of systems and transmits an arbitration result to at least one of the plurality of slave ECUs.

Vehicle control system, vehicle, and control method

An in-vehicle electronic system comprises a core ECU (Electronic Control Unit) mounted in a vehicle and a plurality of slave ECUs that is capable of communicating with the core ECU through an in-vehicle communication network, wherein the core ECU is configured to manage a current time while a main power source of the vehicle is in an off state and manage an activation time of each of the plurality of slave ECUs in a sleep state with a management table while the main power source is in an off state, wherein the core ECU is configured to send an activation signal to each slave ECU through the in-vehicle communication network when the current time becomes the activation time of each of the plurality of slave ECUs while the main power source is in an off state.
