The scalable Contact Sensor System (CoSSy) solution will typically include two to twelve sensors installed at optimal points in the vehicle. Once installed, the CoSSy sensor signals can cover many use-cases, such as the detection of vandalism (scratching) or low-speed parking incidents, because these types of touch are each characterized by a particular sound signature.
Other supported functions of CoSSy include road condition observation, identification of the driver via voice recognition, or detecting approaching emergency vehicles. Even communication with the vehicle via touch could be enabled by CoSSy: A tap at the door by an authenticated driver would suffice to activate an automated door opening. Such functionalities could be especially applicable in the case of car rental and vehicle-sharing, where the process of entry and exit is safe, while that of physical inspection can be made faster and more accurate.
Structure-born and airborne sound are signals which provide valuable information about the immediate vehicle surrounding. CoSSy is specially developed to pick up the sound patterns of several types of contact. Structure-borne sound, for instance, warns when hitting an obstacle at the low-speed level of automated parking.
Once CoSSy is on board, its detection principle can be used to add many more functions thus adding to the safety and comfort of a ride.
