| description | A preparatory sequence for determining the aerodynamic drag surface and/or the rolling coefficient of a vehicle in real conditions of movement, without braking, on a road having a point of departure and a point of arrival, comprises:a) defining a traffic lane with a width less than or equal to 1 m, along the road section,b) performing, by way of the vehicle, a first movement from the point of departure to the point of arrival in the traffic lane, and measuring:the speed of the air relative to the vehicle,the speed of the vehicle at the point of departure and the point of arrival, andthe driving energy supplied by the vehicle along the road section, or considering zero driving energy if the movement is a freewheeling movement.Five methods may be used for determining the aerodynamic drag surface and/or the rolling coefficient. |
