Mercedes filed the patent
Besides the fact that without brakes we would never have had traffic jams, we are glad they were invented. Otherwise you would have to walk home every time you went off the gas too late. Mercedes also thinks that whole brakes could become very big in the future, and filed a patent for a new emergency braking system. Carbuzz discovered the patent for a braking system that partially deflates the tires in an emergency.
Deflating the tires slightly increases the rolling resistance of the tires. This way a car comes to a stop more quickly. The system is primarily intended for electric cars. In regular cars you kick a fluid through brake lines to the brakes, which then squeeze a brake disc. In most electric cars there is no physical connection, but the pedal electrically controls the brake calipers. In addition, electric cars also brake with the engine, making it a complicated interplay.
The calipers are always necessary
When the battery is full, an electric car does not brake via the electric motor to charge the battery. For this, there are still conventional brake discs and calipers among EVs. But if for whatever reason this doesn’t work, Mercedes wants to have a rear guard. Mercedes’ new emergency braking system deflates tires with a valve if it detects that the normal braking system is not working properly. It is technically possible to fill the tires again, just like with serious off-roaders such as the Mercedes G 6×6.
The system is currently not yet built into current models of the brand. For now it is a patent drawing and there is no official announcement yet that the new system will be used. At least last weekend in Qatar it seemed that Valtteri Bottas was allowed to test it for a while.
