Crash-Sensing and Intelligent Restraint Systems


Sensors are the organs of perception of vehicle safety: Recognizing accident risks in split of seconds, they control accident mitigation systems and occupant protection systems accurately, reliably and effectively. Mechanical Electrical Micro Systems (MEMS) such as micro-oscillators or gyros on the scale of micrometers sense even the most subtle movements and shocks and will stabilize the car, prevent vehicle roll and activate the occupant protection systems such as seat belt pre-tensioners, airbags and other protection devices according to crash type and severity. Predictive surround sensors such as radar, LiDAR, cameras and ultrasonic detect accident risks at an early stage and do not only mitigate accidents by automatic emergency braking or evasive maneuvers, but also optimize the effectiveness of occupant protection systems. Since the introduction of seat belt pre-tensioners and driver airbags in the early 80ies the requirements to crash sensors and restraint control electronics have been increased continuously: Starting with single point sensing and focus on frontal crashes with full barrier overlap to trigger driver airbags and seat belt pre-tensioners, all real world accident types and crash severities must be discriminated today utilizing up to a dozen peripheral crash satellites in order to control appropriately up to two dozens of occupant protection devices. New crash tests such as the lateral pole impact or the frontal small overlap crash mandated by regulations and consumer ratings have permanently tightened the requirements to crash sensing and smart restraint control. Above and beyond utilizing the predictive sensors of accident avoidance and advanced driver assistance systems (ADAS), the protection of occupants can be increase significantly: protection devices can be pre-triggered while a crash is imminent, and new protection measures are possible. Last but not least the occupant protection can be adapted and tailored to the occupant size, weight and position (out-of-position) which will be particularly important in autonomous cars with variable seat positions and other new vehicle interior variances. In the seminar, (predictive-) crash sensors, restraint (pre-) triggering crash algorithms and (pre-crash) occupant protection systems are discussed for the following accident scenarios: Frontal- and rear-end collisions, side impact, vehicle rollover, and accidents with pedestrians and cyclists. From scratch, the seminar explains simply and understandably the physical principles of sensors and measuring systems, their properties and application specific benefits and drawbacks, the restraint triggering algorithms in particular. A specific focus is on future safety systems and technologies, such as artificial intelligence / neural networks, and new occupant protection systems in autonomous cars.


The seminar addresses all engineers, technicians and experts working in the development, application and research of vehicle safety, both at automobile manufacturers and tier 1 / 2 / 3 suppliers, system engineers, project engineers and project leaders in particular. Basically, all experts somehow dealing with vehicle safety and being interested in current and future sensor and actuator technologies in passive and active safety are very welcome.
