Continental has developed the new Contact Sensor System (Cossy) that detects low-speed contact between a vehicle and a person or an object. The company has demonstrated at the Consumer Electronics Show, how CoSSY can help to make future use cases like automated parking even safer. A low impact is detected based on the sound signal picked up by CoSSy so that the car can be brought to an immediate emergency stop.
The new safety system detects objects which may be located outside the short-range detection cone of other sensor types. The scalable CoSSy solution will typically include two to twelve sensors installed at relevant locations on the vehicle. After installation is done, the CoSSy sensor signals can cover many more 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.
Road condition observation, an identification of the driver via voice recognition, or detecting approaching emergency vehicles are other supported functions of this new sensor. Also, communication with the vehicle through touch could be enabled by CoSSy such as a tap at the door by an authenticated driver would activate an automated door opening.
“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 a number of types of contact. Structure-borne sound, for instance, warns when hitting an obstacle at the low speed level of automated parking,” says Laurent Fabre, head of the Passive Safety & Sensorics business unit with Continental. “However, once CoSSy is on board, its detection principle can be used to add many more functions this adding to the safety and comfort of a ride.”
