The dynamic headlamp levelling system prevents loss of visibility as well as glare to oncoming traffic over an electronic system which reacts to the compression of the body during braking or accelerating and maintains the position of the headlight in a definite state.
This technology is explained on the basis of the illustration presented above. The pitching motion that follows braking (brake-dive), results in a loss of the range of illumination of the headlamps, while on the other hand, the acceleration related motion of the body (squat), results in the headlamps glaring into oncoming traffic. The operation of dynamic headlamp levelling is shown in the lower diagram. The loss of visibility or the glare on oncoming traffic is compensated and the postion of the headlamp is adjusted in such a way that a fixed level is maintained. The application of dynamic headlamp levelling is expected in the latest Japanese models coming into the market.
