Mercedes technology that deflates the wheels in emergency situations

Mercedes-Benz is developing several technologies in parallel, and one of them has the gift of revolutionizing braking systems.

The Stuttgart-based manufacturer has recently filed a patent with the World Intellectual Property Office for a backup brake device that will help the driver behind in an emergency.

How does the device work?


The device designed by Mercedes engineers will be connected to the tire valve, and if the braking system fails in an emergency brake, this device will instantly deflate the tires to help the car slow down safely.

In the documents accompanying the patent of Mercedes and discovered by those from Carbuzz it is noted that this spare braking device would be implemented on the hybrid and electric vehicles that the German manufacturer will produce in the future. However, it can also be used on conventional cars equipped with internal combustion engines.

A deflated tire, ie flatter, has a larger contact area with the tread, which determines the rolling resistance. However, there is a risk that the tire pressure will drop too much and the tire can easily come off the rim. At the same time, it can have a detrimental effect on the maneuverability of the vehicle.

But Mercedes-Benz also thought about it. The device designed by Stuttgart engineers will be mounted on all four wheels so that the pressure drops evenly on both axles. After the pressure is reduced, the car will slow down, and the driver will be notified that the tire pressure has suddenly dropped through a warning system.

The spare braking system can also be used in reverse, ie to increase the tire pressure to the level recommended by the manufacturer that the device designed by Mercedes-Benz will “know”. In combination with a tire pressure monitoring system, a vehicle equipped with such a system will be able to adjust its tire pressure in real time.
