Abstract
The present invention discloses a mm-wave radar sensor to be deployed in the vehicles for sensing driver fatigue. The key system relevant components are utilization of mm-wave integrated radar, with specific planar high gain antenna radiation pattern, by analyzing at least two major biometric parameters of the drives simultaneously: heartbeat and respiratory dynamics. The method of operation calculates probability of the fatigue event. In case that probability is above a predefined threshold, the interaction with vehicle control system is initiated, using typical arbitrary automotive interfaces. Corresponding predefined actions are taken in that case. The predefined actions could be one or combination of the following: driver safety belt pulling, audio signal alerts to driver, vibration alert to driver, inside cabin light condition changes, engine operation condition change, corresponding communication using arbitrary wireless means to outside vehicle environment. Optionally, the system is utilizing additional driver imposed parameters like acceleration sensor information. Preferably, the system is using 60 GHz or 77-79 GHz integrated radar front end working in Doppler operation mode, with 4×4 Tx and Rx planar radiation elements, with physical size typically in the range 4×2×1 cm, or smaller.
