With the introduction of different types of airbag systems, different types of crash sensors are required, too. Early airbag systems used mechanical crash sensors. The next big step in the development of airbag control modules was the introduction of so called single point sensing systems. The early generation of sensors has been piezoelectronic sensors, followed by bulk micromachined resistive sensors and surface micromachined capacitive sensors. An improved discrimination of the crash pulse became possible with the development and introduction of this type of sensors. For both active and passive future safety system application of a new generation of sensors and sensing systems becomes necessary to fulfil the requirements of the safety systems. Depending on the range of the sensors, the information is used for driver warning, driver assistance and crash avoidance. The signals can also be used for activation of a restraint system with a much higher precision and a better restraint performance compared to today's systems. A first generation of a proximity sensor consists of an optical sensor system mounted behind the windscreen. The sensor principle is based on the speed of light. Besides the primary function of the proximity sensor, secondary functions like rain sensor or light sensor are also possible. A further application of the CV (closing velocity) sensor is to use it as a sensor for a pedestrian protection system. Part of future safety systems will be a sensor bus system that includes all the sensors which are necessary to provide an optimum on passenger protection.
