摘要：<p>The device comprises at least three optical fibre coils 21 - 23 mounted near the outer surface of the vehicle and incorporates the following: (a) means 10 - 11 for injecting light into the input of each coil, the light being of the same kind, having the same phase and consisting of a first and second component, (b) means 12 for analysing the phase differences between the first components (taken in pairs) of the light emerging from the coils and the phase differences between the second components (also taken in pairs) of the light emerging from the coils, and (c) means 13 for calculating the resultant aerodynamic force from the phase differences so measured and from the speed of the vehicle. A knowledge of the resultant force can be used to warn the driver or to control an automatic correction of the steering angle of the driving wheels of the vehicle. <IMAGE></p>
