Closing Velocity (CV) Sensor - optoelectronic pre-crash sensing system for the next generation of occupant safety systems.

We are developing new technologies for a future pre-crash sensor system based on a microoptical laser sensor. This involves the dynamic determination of the distance to an emerging obstacle as well as calculating the differential velocity with which the vehicle and obstacle are approaching each other. The detection and evaluation of the obstacle are both based on a highly precise laser runtime measurement. The scene is illuminated by a very short laser pulse. The pulses reflected by the object are recorded over PIN diodes.

• Laser based optical system
• Optimized crash performance
• Vehicle structure independent
• Optimized activation of reversible restraints devices
