An automotive sensor system is being designed to increase driver awareness in adverse weather conditions. The system can be divided into two sections: detection in the blind spots, and front-rear long range detection. The former will provide the driver with a visual indication whether or not someone is in the blind spot. The latter will tell the driver the distance to an obstacle in front (or behind) up to a distance of 1600 feet. Critical minimum and maximum distances were calculated, and appropriate sensors were selected. Ultrasonic sensors were selected for the blind spot region because of their low cost, acceptable attenuation, and small size. The preliminary selection for long-range detection is millimeter wave sensors because of their low attenuation (even in adverse weather conditions) and small angular resolution. Their cost, while high, should still be within budget.
