Whether in aircraft, trains or cars – ABS has revolutionised the safety of all vehicles. It would now be unthinkable not to have it. But the path to this breakthrough was long: Bosch announced a patent for a “device to prevent hard braking of the wheels on a motor vehicle” as early as 1936. Yet all designs were unsuccessful until the end of the 1970s. They were too delicate and complex and were unsuitable for series production.
MAN together with Bosch and Knorr filled this gap for commercial vehicles. These companies presented ABS at the International Motor Show in Frankfurt in 1981 after ten years of development. MAN subsequently offered ABS as special equipment. It has been fitted as standard in all MAN buses since 1987 and also in trucks MAN introduced the anti-lock braking system into series production at the beginning of the 1980s. This safety feature remains effective today. since 1990. The development of ABS enabled a vehicle to remain on track in extreme road conditions like snow, ice or a slippery surface for the first time. Where the wheels previously locked during abrupt braking, with ABS a vehicle was now easier to control. ABS prevents wheels from locking by electronically increasing or reducing the brake pressure applied to individual wheels as needed. So stopping distance remains short even on slippery surfaces and the vehicle can be steered. This feature continues to ensure greater safety on the roads.
It was an innovation: ABS enabled brake pressure to be applied to each wheel individually for the first time.
The feature enables shorter braking distances and ensures significantly more safety.
Aviation laid the foundation stone for ABS: aircraft have to remain on course on the runway during landing.
