Abstract

An airbag jacket activating system includes radio communications transceivers configured to make RF communications and LF communications, respectively. An acceleration sensor configured to detect acceleration of a motorcycle. An update unit configured to update an LF communications ID, to code the updated LF communications ID together with an RF communications ID, and to transmit the coded updated LF communications ID and the coded RF communications ID to an airbag jacket through RF communications. An update unit configured to store the updated LF communications ID in a case where the LF communications ID is received together with the RF communication ID. A control unit configured to cause the coded RF communications ID and an ignition signal to be transmitted through the RF communications, and to cause the LF communications ID and the ignition signal to be transmitted through the LF communications when the acceleration exceeds a predetermined value;

Dependent claims

An airbag jacket activating system comprising:

radio communications means configured to make radio communications between a vehicle and an airbag jacket;
acceleration detecting means configured to detect acceleration of the vehicle;
on-vehicle control means configured to transmit deployment instruction data on the airbag jacket to the airbag jacket through the radio communications means in a case were the acceleration detected by the acceleration detecting means exceeds a predetermined value;
and
in-jacket control means configured to deploy the airbag jacket when receiving the deployment instruction data transmitted from the on-vehicle control means;
wherein the radio communications means comprises:
high-frequency radio communications means configured to make radio communications by use of a high-frequency band;
and
low-frequency radio communications means configured to make radio communications by use of a low-frequency band;
the vehicle further comprises:
on-vehicle storage means configured to store a high-frequency ID and a low-frequency ID;
and
on-vehicle update means configured to update the low-frequency ID at a predetermined timing, to code the updated low-frequency ID together with the high-frequency ID, and to transmit the coded updated low-frequency ID and the coded high-frequency ID to the airbag jacket through the high-frequency radio communications means;
the airbag jacket further comprises:
in-jacket storage means configured to store the high-frequency ID and the low-frequency ID;
and
in-jacket update means configured to collate the high-frequency ID transmitted from the on-vehicle update means with the high-frequency ID stored in the in-jacket storage means, and to store the updated low-frequency ID in the in-jacket storage means when receiving the updated low-frequency ID together with the high-frequency ID whose collation succeeds;
when the acceleration detected by the acceleration detecting means exceeds a predetermined value, the on-vehicle control means causes the coded high-frequency ID and the deployment instruction data to be transmitted through the high-frequency radio communications means, and causes the low-frequency ID and the deployment instruction data to be transmitted through the low-frequency radio communications means;
and
the in-jacket control means receives the deployment instruction data which is transmitted together with any one of the high-frequency ID and the low-frequency ID, and thus deploys the airbag jacket.
