Intelligent driving warning system

Abstract

An intelligent driving warning system is disclosed for detecting the physiological state of a driver while driving a vehicle. The system includes multiple electrodes, a control module, and a mobile device. The electrodes are disposed on a steering wheel of the vehicle and arranged along its circumference. The control module is disposed in the vehicle and electrically connected to the electrodes. The mobile device is signal-connected to the control module. When the driver holds the steering wheel with both hands, at least two electrodes contact the driver's body, forming a conductive path. This causes the control module to generate the driver's heart rate data, which is transmitted to the mobile device and displayed on the mobile device via a display interface.
