With AB12, Bosch offers airbag control units that are scalable for all markets, vehicle segments and platforms. These occupant protection electronic modules can be adapted for varying customer hardware and functionality requirements.

The airbag control unit AB12 base is flexible and scalable with respect to the number of firing loops and sensor interfaces for peripheral crash sensors. The airbag control unit can trigger up to 32 firing loops and control 12 PSI5 sensor interfaces. There is also the option to expand the control units to trigger up to 48 firing loops and control up to 18 sensor interfaces.

High-g sensors and optional rollover sensors are already integrated into the control unit of the variant AB12 base.

The accuracy of the algorithms used to detect front, rear-end and side crashes as well as rollovers has been further improved in comparison with the previous version, partly as a result of the addition of a new algorithm based on the parameters of the kinetic energy absorption in crash (KEC).

The AB12 control unit evaluates the data from the pressure sensors to detect side crashes and from the acceleration sensors to detect side, front and rear-end crashes. In accordance with the PSI5 standard, the peripheral sensors can be operated either on a sensor bus or via a point-to-point connection.

 
 
 
  • Configurable for all markets, vehicle segments and platforms
  • Flexibility in the use of connector systems
  • Integration of inertial sensors possible
  • Modular integration of both established and new algorithms
  • Safety concept compliant with ISO 26262
  • Use of Bosch electronic components
 
 
 

With the airbag control units AB10 light, Bosch is offering a solution that fulfills basic occupant protection requirements. It has been specially developed for low-price vehicles, which are rapidly becoming a common sight in emerging markets such as China, India and Brazil. AB10 light supports the objective of making airbags standard worldwide, and consequently therefore of making safety available for all.

The airbag control units AB10 light are based on our standardized control unit concept and utilizes established and proven Bosch electronic components (e.g Bosch system ASICs).

Despite the standardized product concept, AB10 light can be adapted to a variety of requirements. The scalable control unit design offers up to 12 firing loops and up to four interfaces to peripheral sensors.

The airbag control unit AB12 plus is flexible and scalable with respect to the number of firing loops and sensor interfaces for peripheral crash sensors. The airbag control unit can trigger up to 32 firing loops and control 12 PSI5 sensor interfaces. There is also the option to expand the control units to trigger up to 48 firing loops and control up to 18 sensor interfaces.

With the AB12 plus variant Bosch has developed a concept which integrates the airbag control and the ESP® inertial sensors into one compact airbag control unit, saving both space and cost. There is also the option of extending the AB12 plus variant with a complete set of angular rate and acceleration sensors for all three dimensions (6D), meaning that chassis systems are also supported in addition to the ESP® and rollover-protection features.

The accuracy of the algorithms used to detect front, rear-end and side crashes as well as rollovers has been further improved in comparison with the previous version, partly as a result of the addition of a new algorithm based on the parameters of the kinetic energy absorption in crash (KEC).
