A communication device including a communicator and a communication controller is provided. The communicator has at least two communication ranges including a short communication range and a long communication range longer than the short communication range. The communication controller permits the communicator to perform communication with a terminal present in the short communication range regardless of a priority level of the terminal. The communication controller permits the communicator to perform communication with a terminal present in the long communication range and out of the short communication range when a priority level of the terminal is higher than a predetermined priority level.

Communication device

A vehicle control apparatus includes: a first communicator that has a communication range outside a vehicle and communicates with a portable communication terminal by a predetermined first wireless communication system; a second communicator that has a communication range in a vehicle compartment of the vehicle and communicates with the portable communication terminal by a second wireless communication system; a first authenticator that receives identification information from the portable communication terminal; a second authenticator that receives identification information from the portable communication terminal; a determinator that determines that the portable communication terminal exists within a predetermined range outside the vehicle, and determines that the portable communication terminal exists in the vehicle compartment of the vehicle; and a controller that permits or causes an electronic control device controlling an action of the vehicle to perform a predetermined action.

Vehicle control apparatus

A secondary device receives an instruction message accompanied by a counted value and compares the received counted value with a counted value stored in an internal memory. Thus, it is determined whether the currently received instruction message is the same as a previously received instruction message and an execution of a process based on the previous instruction message was completed. When the received instruction message is not the same, the secondary device transmits a response message after executing a process according to the received instruction message. In contrast, when the instruction message is the same, the secondary device transmits a response message based on a process history in the internal memory without executing the process according to the received instruction message.
