Passenger protecting device for vehicle
First Claim
1. A passenger protecting device for a vehicle, comprising:
- a passenger protecting unit to be arranged in the vicinity of a passenger on the vehicle, for protecting the passenger, a plurality of terminal units arranged in the vehicle, for detecting a plurality of information about the passenger and a loadage on the seat; and
a central control unit which communicates with the plural terminal units through a single communication line at intervals of a predetermined cycle thereby to collect the plural information and which determines the operating condition of the passenger protecting unit and also controls the operation of the passenger protecting unit;
wherein the central control unit carries out the communication with at least one terminal unit detecting an information of high priority at every interval of the predetermined cycle and also carries out the communication with the other terminal units detecting other information of low priority in a sequential manner such that communication occurs with a different terminal unit detecting low priority information than in an immediately adjacent interval.

Abstract
A passenger protecting device for a vehicle includes a central control unit. The central control unit communicates with a plurality of terminal units through a single communication line at intervals of a predetermined cycle to collect the plural informations. The central control unit further determines the operating condition of a passenger protecting unit and controls the operation of a passenger protecting unit. The central control unit carries out the communication with slave units (1, 2) detecting the informations of high priority at intervals of a predetermined cycle T0 and also carries out the communication with slave units (3, 4) detecting other informations of low priority in sequence at intervals of the predetermined cycle T0. Consequently, without changing the communication method with the plural terminal units before and after the vehicle'"'"'s collision, the device can collect the informations of high priority at short intervals and the informations of low priority at long intervals.

6. A method of protecting a passer in a vehicle using a passenger protecting device for a vehicle, comprising:
-
a passenger protecting unit to be arranged in the vicinity of a passenger on the vehicle, for protecting the passenger, a plurality of terminal units arranged in the vehicle, for detecting a plurality of information about the passenger and a loadage on the vehicle; and
a central control unit which communicates with the plural terminal units through a single communication line at intervals of a predetermined cycle thereby to collect the plural information and which determines the operating condition of the passenger protecting unit and also controls the operation of the passenger protecting unit;
the method comprising the steps of;
carrying out the communication with at least one terminal unit detecting an information of high priority at every interval of the predetermined cycle; and
carrying out the communication with the other terminal units detecting other information of low priority in a sequential manner such that communication occurs with a different terminal unit detecting low priority information than in an immediately adjacent interval. - View Dependent Claims (7, 8, 9, 10)
