Method for generating speed warning based on status of e.g. primary driver in motor vehicle, involves adding predetermined speed buffer to speed limit, and generating warning when speed signal is larger than speed limit and speed buffer

摘要

The method involves receiving a vehicle speed signal that indicates speed of vehicle on a road, and receiving a speed limiting signal that indicates an indicated speed limit of the road, where the vehicle is driven on the road. A predetermined speed buffer is added to the speed limit, and the speed limit and the speed buffer are compared to the vehicle speed signal. A warning is generated when the vehicle speed signal is larger than the speed limit and the speed buffer. A driver identification signal is received for indicating a driver is a primary driver or a secondary driver. An independent claim is also included for a device for generating a speed warning to a primary driver or a secondary driver in a vehicle.
