Abstract
A vehicle control system includes an entry ECU that performs first authentication processing for access from an outside of a vehicle, a door control ECU that controls locking and unlocking of a door of the vehicle, and a central ECU, the entry ECU transmits a first startup request, which instructs to start up the central ECU, before executing the first authentication processing, and the central ECU transmits a second startup request which instructs to start up the door control ECU.
Claims10
A vehicle control system mounted on a vehicle, the vehicle control system comprising:
- an entry ECU that detects access to the vehicle from an outside of the vehicle and executes first authentication processing on the access which is detected;
- a first communication bus to which the entry ECU is connected;
- a door control ECU that controls locking and unlocking of a door of the vehicle;
- a second communication bus to which the door control ECU is connected;
- and
- a central ECU having a gateway function of managing signal transmission between the first communication bus and the second communication bus, wherein
- the entry ECU transmits a first startup request, which instructs to start up the central ECU, to the central ECU before executing the first authentication processing when the access is detected, and
- the central ECU transmits a second startup request, which instructs to start up the door control ECU, to the door control ECU in response to reception of the first startup request.
An entry ECU that processes access to a vehicle from an outside of the vehicle, the entry ECU comprising:
- an access detection unit that detects the access;
- an authentication processing unit that executes an authentication process on the access which is detected;
- and
- a startup request unit that transmits a startup request that instructs to start up another ECU, wherein
- the startup request unit transmits the startup request before execution of the authentication process when the access is detected.
