Title: DEVICES AND METHODS FOR MONITORING DRIVER BEHAVIOUR
Abstract:
Methods and devices for monitoring driver behaviour in a vehicle are disclosed. In one aspect, a method is provided for monitoring driver behaviour in a vehicle using a device comprising a three-axis accelerometer. The method comprises identifying a horizontal plane of the device when the vehicle is stationary repeatedly deriving, from an output of the accelerometer, an acceleration vector resolved in the horizontal plane, repeatedly comparing the magnitude of the resolved acceleration vector with an orientation- independent pre-determined threshold value during operation of the vehicle, and initiating a high-risk event response protocol of the device when the magnitude of the resolved acceleration vector exceeds the orientation-independent pre-determined threshold value. The device may include a connector arranged to mate with an accessory socket of the vehicle and to receive an electrical supply from the vehicle when the device is mated with the socket and a detector module configured to determine a connection state of the device and an engine running state of the vehicle based on voltage measurements at the connector.
