The cause of many accidents is drowsy driving. Many people become very fatigue when driving, which could cause harm to many drivers around them. Also, microsleeps may occur, which are short periods of sleep that happen for a couple of seconds. When this happens, anything accident can happen. Someone may collide with another car or may run off the road.

Recently, Bosch, an engineering company, created a steering-angle sensor, and the company was able to implement this in many of their cars. This sensor can detect the steering angle and the velocity the steering-angle moves. At the beginning of the trip, the sensor records the driver’s steering patterns. The sensor can then realize changes that occur during the trip. The sensor can tell if the driver is slowly dozing off if the driver begins to stop steering but then moves the wheel abruptly. This is a typical way the sensor can tell if a driver is slowly dozing off. If the sensor evaluates the driver as “drowsy,” a coffee cup flashes in the instrument panel.

Bosch has made another sensor, but this sensor uses a camera. The camera is within the steering wheel, which allows the camera to see the face of the driver. This camera can detect when a driver gets distracted, looks away, and when their eyelids become heavy. If the sensor assesses the driver as tired, then it will provide an alert.

Nearly 80,000 crashes in America are related to drowsy driving. This technology will be able to save many lives soon. As time goes by, the sensor gets more technologically advanced and will be able to evaluate the “tiredness” of the driver.
