Abstract:
A direction control apparatus with a sensor, a method for determining a driver status using the driving control apparatus, and a system for determining the driver status are provided. The direction control apparatus includes at least a pressure sensor to sense a plurality of pressure values applied to multiple positions of the direction control apparatus. When the pressure values are received by a controller of the apparatus, the driver status can be determined according to a change of pressure values over time, or further a change of the positions where pressure is applied. The system can connect with an autopilot system and an alarm system of a vehicle via the controller. Therefore, the system incorporates an autopilot system and issues an alarm when the driver status is determined to be abnormal.
