Patent

CA 2142497

In a system for a wireless transmission of energy and data between the vehicle side and the steering wheel side of motor vehicles by means of a transformer for a transmission of energy from the vehicle side to the steering wheel side and for a two-way transmission of data, circuit means for controlling the transmission sequence and for res- ponding to the transmission are provided on both sides of the transformer. Said circuit means comprise on the steering wheel side and on the vehicle side a micro- controller. At least the microcontroller on the vehicle side controls an interface module and is connected to the igniting circuit of a gas bag unit which is accom- modated in the steering wheel and serves for protection in case of an impact. To eliminate the need for a separate unit for activating the igniting circuit of the gas bag unit for protection in case of an impact, an acceleration sensor for activating the igniting circuit is connected to a microcontroller which is pro- vided on the vehicle side or on the steering wheel side.
