Summary: | The data transmission system is used between a control device (1), for activating the passenger restraints and a number of collision sensors (4,5,6) providing the collision signals evaluated by the control device, coupled to the latter via at least one data line (18,19). The data is transmitted via a pulse width modulated signal, with its actual period duration compared with a required period duration, for providing a validity check. Pref. the data exchange is effected via an interrupt signal transmitted by the peripheral collision sensor, with serial data transmission, the required period duration of the pulse width modulated signal pref. being 500 microns. |
