Abstract: A vehicular driving assist system includes a sensor disposed at a vehicle and operable to capture sensor data. An electronic control unit (ECU) includes electronic circuitry and associated software, and the electronic circuitry includes a data processor for processing sensor data captured by the sensor. The vehicular driving assist system, via processing at the data processor of sensor data captured by the sensor, detects a tread of a tire of the vehicle. The vehicular driving assist system determines a tread depth of the tread of the tire. The vehicular driving assist system, responsive to the determined tread depth being below a threshold tread depth, generates a worn tire signal to alert a driver of the vehicle that that the determined tread depth is below the threshold tread depth.

Abstract: A fog detecting system for a vehicle includes a camera disposed at a vehicle and having a field of view forward of the vehicle, and a non-imaging sensor disposed at the vehicle and having a field of sensing forward of the vehicle. The camera captures image data and the non-imaging sensor captures sensor data. A control includes at least one data processor operable to process image data captured by the camera and sensor data captured by the non-imaging sensor. The control, responsive to processing of image data captured by the camera and processing of sensor data captured by the non-imaging sensor, determines presence of fog ahead of the vehicle and in the field of view of the camera and in the field of sensing of the non-imaging sensor.
