First controller for recognising at least one vehicle passenger being in danger, second controller for controlling an electrically motorised seat belt tightener, device for controlling an electrically motorised seat belt tightener and method for controlling an electrically motorised seat belt tightener

摘要

The controller has an interface (IF1) providing a sensor signal and another interface (PSI1) enabling a bi-directional communication with another controller for control of an electromotive pretensioner. The latter interface provides a breakdown signal to a breakdown sensor system and the latter controller is configured for the transmission of a control instruction. An evaluation circuit determines the endangerment depending on the sensor signal and sends a control instruction over latter interface. The control instruction is introduced in a cycle for the transmission of the breakdown signal. Independent claims are also included for the following: (1) a controller for controlling an electromotive pretensioner (2) a device for controlling an electromotive pretensioner (3) a method for controlling an electromotive pretensioner.
