Bosch AB12 Light, Scalable Airbag control unit

With airbag control unit, generation 12 (AB12), Bosch offers airbag control units that are scalable for all markets, vehicle segments and platforms. The occupant protection electronic modules can be adapted for varying customer hardware and functionality requirements. The AB12 evaluates the data from the internal and external acceleration and pressure sensors to detect side, front and rear-end crashes. The external peripheral sensors are connected via a bus system or point to point in accordance with the peripheral sensor interface (PSI5) standard. Using firing loops, the AB12 controls the deployment of different restraint systems, such as airbags and seat belt tensioners. Data coming from an occupant sensing system is used to individually optimize the restraint system according to the size/weight of the occupants. Additionally, the AB12 sends acoustic and/or visual warning signals, if the passenger airbag is disabled and the system is not functional. For pedestrian protection, data from acceleration sensors or a pressure tube sensor integrated in the bumper can be used to lift up the hood. This reduces the injury level of the pedestrian’s head, in case of an accident. In the airbag control unit, a memory element is integrated which stores relevant data right before and after a crash occurred.

Bosch AB12 Light, Scalable Airbag control unit

The central sensing airbag control unit AB12 light is one of the world’s smallest and lightest airbag control units. It is designed to meet the basic occupant protection requirements of the low price vehicle segment. Despite the standardized product concept, AB12 light can be adapted to a variety of requirements. The scalable control unit design offers up to 16 firing loops and up to 6 interfaces to peripheral sensors.
