Transmitter, trigger device, ID code registration system, and ID code registration method

A trigger device configured to transmit a trigger signal to a transmitter that is mounted on each of a plurality of wheel assemblies included in a vehicle and executes a process in accordance with a command included in the trigger signal, wherein the transmitter is configured to function in one of a plurality of formats that are selectable by a command included in the trigger signal, the trigger device comprising:

• a reception unit configured to receive a signal transmitted from the transmitter;
• a trigger device memory;
• and
• a trigger device controller configured to control the trigger device, wherein
• the trigger device controller is configured so that when the trigger device controller receives a signal transmitted from the transmitter with the reception unit in response to the trigger signal that includes a command designating the format, the trigger device controller stores an ID code included in the signal in the trigger device memory, and
• the trigger device controller is configured so that when the trigger device is connected to an in-vehicle receiver, the trigger device controller transmits the ID code stored in the trigger device memory to the in-vehicle receiver in order to register the ID code to the in-vehicle receiver.

An ID code registration system comprising:

• a transmitter that is coupled to each of a plurality of wheel assemblies included in a vehicle and configured to function in one of a plurality of formats that are selectable by a command included in a trigger signal;
• and
• a trigger device that transmits the trigger signal to the transmitter, wherein
• the transmitter includes
• a pressure sensor configured to detect a pressure of a tire and output a detection result of the pressure to a controller,
• a memory that stores an ID code and various programs to control the transmitter,
• a transmission unit configured to transmit a signal,
• the controller configured to control the transmitter, and
• a trigger reception unit configured to receive the trigger signal,
• wherein the controller is configured so that when the controller receives the trigger signal including a command designating a format of the transmitter with the trigger reception unit, the controller selects a program for having the transmitter function in the designated format and has the transmission unit transmit a signal including the ID code to register the ID code to an in-vehicle receiver, and
• the trigger device includes
• a reception unit configured to receive a signal transmitted from the transmitter,
• a trigger device memory, and
• a trigger device controller configured to control the trigger device, wherein
• the trigger device controller is configured so that when the reception unit receives the signal including the ID code, the trigger device controller stores the ID code included in the signal in the trigger device memory, and
• the trigger device controller is configured to so that when the trigger device is connected to the in-vehicle receiver, the trigger device controller transmits the ID code stored in the trigger device memory to the in-vehicle receiver in order to register the ID code to the in-vehicle receiver.
