Autoliv, a developer, manufacturer and supplier of automotive safety systems, has introduced a new system, the Torricelli Vacuum Brake (TVB), which uses a vacuum-induced plate for auto-emergency stopping situations in cities. The system can bring a car to a halt in a fraction of the distance it takes with normal braking.
The vacuum plate, located under the chassis of the vehicle, deploys forcefully downwards. When connecting with the ground, it creates a suction effect that temporarily sticks the plate to the ground like an anchor, increasing braking distance by up to 40 percent.
It sounds strange, but Autoliv has tested the system, and they claim it’s entirely practical. The system is apparently so effective that it has been restricted to speeds of 70 km/h (40 mph) and under. At higher speeds, the vehicle would stop so suddenly it could pose serious safety risks for drivers.
The TVB is also designed to function with autonomous and semi-autonomous vehicles. Many of these use radar systems to judge when it’s appropriate to brake in relation to distance from other vehicles.
Autoliv’s system is intended for emergency braking situations only, where traditional braking technology isn’t enough to bring the vehicle to a complete stop. A car losing control on black ice is an example of such a scenario.
When braking with the TVB, airbags will not deploy, so seat belts will be the primary safety mechanism in preventing injuries to car occupants.
If this system had been developed by any firm other than a major safety systems developer like Autoliv, the system may never have been seen as something practical. Let us know your thoughts in the comments below.
