Abstract

See full text

The present invention relates to a vehicular control device including a plurality of ECUs connected to each other through an in-vehicle network. The vehicular control device includes a first control device that controls an electrical component and a second control device connected to the first control device through an in-vehicle network. In a case where an operation switch of the electrical component in the first control device is fixed in an on-state and an ignition key is off, data transmission from the first control device to the second control device is stopped, or the first control device is set to a reception-only mode, and thus the second control device is prevented from operating due to a wake-up function.
