System 4Control of Renault

The third generation of Renault Laguna arranges of a system, 4Control, that offers him a high precision in the direction. In our blog dedicated to the world of the engine we analyze as there works this system and the advantages that it contributes to the vehicle that mounts it.

Four wheels guidelines with which the Lagoon is provided, provide to the berlin of Renault exceptional, of a stability and manageability. The key of the system 4Control there are a few rear wheels which draft angle is governed electronically according to the speed to which the vehicle journeys.

This system is not completely new in the car industry, since it is used for any time by trucks and buses of three or any more axes to help them to reduce his draft angle, facilitate his handling and maneuver capacity. The Deep Japanese signature developed it for some of his models but his implantation did not turn out to be viable and left the project. At present and thanks to the development of the electronics in the cars it is possible to direct the wheels of sure and efficient form.

You mark of both prestige and BMW, it 7 already include in his Series ó in the ceiling of scale of the series 5, the GT. Renault saw in this system an important help for the conduction and an increase in the safety of the car. 4Control it makes the conduction more relaxed since it is necessary to turn the frill less times in maneuvers like a parking or on having gone along along much toned mountain highways.

How does it work?:

When the car circulates below 60 km / h, the wheels of the rear axis turn in the sense opposite to those of the forward for a major agility. The radio reduced of draft facilitates many of the maneuvers that we carry out especially in city. Four wheels guidelines the movements of the frill stretch the being to be more limited, what helps to avoid the weariness when we circulate along narrow highways or with many curves.

If we circulate over 60 km / h, the behavior of the rear wheels is identical to that of the front parts, turning the four in the same sense. On having taken a curve, the rear train adapts itself perfectly to the trajectory and the vehicle obtains a maximum stability and a perfect maintenance of the direction.

With this system 4Control the radio of draft of the Lagoon goes on from the habitual 12,05 meters to 10,8 meters, 10 % less.
