Aisin System Checks Drivers for Human Error

Aisin Seiki Co. Ltd. is developing a "human error monitoring system" that can detect when a driver is distracted, drowsy or in medical distress. If necessary, it also can take control of the car and summon aid.

The company will demonstrate the technology to reporters next week at the Detroit auto show.

When the monitor senses trouble, it sounds an audio warning and vibrates the seat. If the driver fails to respond, the experimental system automatically applies the brakes, steers the vehicle to a stop on the edge of the road and uses the driver's smart phone to send a call for help.

The Aisin system bases its assessment of the driver's welfare on input from sensors in the seat that check the driver's breathing rhythm, heart rate and body movements. An infrared camera on the steering column looks for signs of inattention or drowsiness. The company says it also is developing a technology to assess a driver's state of mind by monitoring brain waves.
