Controller and control system for an occupant protection device in a motor vehicle and method of transmitting data in the control system
First Claim
Patent Images
1. A controller for an occupant protection device in a motor vehicle, comprising:
- a control unit with a first interface for receiving data and a second interface for data transfer with a control device disposed remote from said controller, the control device being operable in dependence on vehicle-specific characteristic operating values, said control unit having a non-volatile memory;
said control unit receiving signals at said first interface containing vehicle-specific characteristic operating values for the control device and transferring the characteristic operating values to said second interface for transmission to the control device, said control device having a memory; and
said vehicle-specific characteristic operating values transmitted to the controller after manufacture of the controller but before putting the motor vehicle into operation.

Abstract
A controller for an occupant protection device in a motor vehicle includes a control unit, a first interface for receiving data, and a second interface. The second interface effects data interchange with a control device remote from the controller and operable with vehicle-specific characteristic operating values. After the controller has received vehicle-specific characteristic operating values for the control device, the characteristic operating values are passed on via the second interface to the control device and are stored there.

13. A method of transmitting data in a control system for an occupant protection device in a motor vehicle, between a controller and at least one control device, operable in dependence on vehicle-specific characteristic operating values, and including at least one memory, the method which comprises:
-
transmitting to a controller of a control device in a motor vehicle occupant protection device only characteristic operating values relevant for the operation of a respective control device in a selected vehicle type, the characteristic operating data stored in a non-volatile memory of the controller; and
subsequently, with the controller, passing on the characteristic operating values to the control device and storing the characteristic operating values in a memory of the control device; and
transmitting the vehicle-specific characteristic operating values to the controller after manufacture of the controller but before putting the motor vehicle into operation. - View Dependent Claims (14, 15)
