  • Publication number: 20100114445
    Abstract: A driving assistance method for a motor vehicle is disclosed. It is characterised in that the method comprises the steps of detecting an obstacle located in proximity to the motor vehicle, calculating the slope of a road on which the motor vehicle is capable of travelling, determining, depending on the calculated slope of the road, a speed limit beyond which the motor vehicle will strike the obstacle, and if an obstacle is detected, automatically reducing the speed of the motor vehicle if this is greater than the speed limit.
