Automatic car side-view and rear-view mirrors adjustment and drowsy driver detection system

A smart driver safety system for a vehicle, comprising:

• a plurality of ultrasonic sensors configured to generate ultrasonic measurements of a head and an upper body of a driver of the vehicle;
• a first infrared camera configured to measure a plurality of features on the driver's face;
• a drowsy driver detector connected to the plurality of ultrasonic sensors and the first infrared camera, the drowsy driver detector including an electrical circuitry, a memory configured to store program instructions and a microprocessor configured to execute the program instructions to:
• determine a head position of a driver;
• determine when the upper body is in a slouched position;
• detect an eye position of the driver's eyes;
• determine when the eyes of the driver are closed:
• when the driver's eyes are closed, determine a time duration of an eye closure;
• compare the time duration to a drowsiness threshold;
• when the eye closure exceeds the drowsiness threshold, generate a drowsiness alert signal:
• an attention diversion monitor connected to the drowsy driver detector, wherein the attention diversion monitor is configured to detect deviations of the eyes of the driver from a straight ahead position and provide an attention diversion alert signal;
• a plurality of actuators connected to the drowsy driver detector, wherein the plurality of actuators are configured to provide at least one of the drowsiness alert and the attention diversion alert;
• an automatic mirror adjustment subsystem connected to the drowsy driver detector, wherein the automatic mirror adjustment subsystem is configured to determine, from the head position and the eye position, when the driver cannot see at least one side mirror of the vehicle and adjust the least one side mirror to a position in which the driver can see the at least one side mirror;
• and
• a seat pressure sensor configured to detect a weight of a seat occupant of a driver's seat of the vehicle;
• wherein the microprocessor is configured to:
• receive the weight;
• compare the weight to a weight threshold;
• when the weight is less than the weight threshold, determine that the seat occupant is not the driver;
• and
• when the weight is equal to or greater than the weight threshold, determine that the seat occupant is the driver and activate the drowsy driver detector;
• wherein the seat pressure sensor comprises at least two strain gauge load cells located beneath the driver's seat, wherein the at least two strain gauge load cells generate strain gauge signals, and wherein the seat pressure sensor is configured to determine the weight based on the strain gauge signals.
