Adaptive brake light: Effective warning of imminent rear-end collisions
- Available as standard equipment in the Mercedes-Benz S-Class since February 2005
- Braking distance reduced by more than four metres at a speed of 80 km/h
Along with Brake Assist PLUS, Mercedes engineers have developed another system to help reduce the high number of dangerous rear-end collisions that occur on the road. This new technology more effectively warns drivers travelling behind of the danger of a rear-end collision by causing the front vehicle??????????????????????????????????????s brake lights to blink in critical situations.
Studies conducted by experts in Sindelfingen, Germany show that drivers?????????????????????????????????????? braking reaction time can be shortened by up to 0.2 seconds on average if a blinking red warning light is substituted for a conventional brake light in emergency braking situations. As a result, the braking distance can be reduced by approximately 4.4 metres at a speed of 80 km/h, and by as much as around 5.5 metres at 100 km/h. As such, blinking brake lights are an effective and easily implemented measure for helping to prevent rear-end collisions. A key positive aspect of the new system is that it makes driving safer even for those motorists who do not own a Mercedes-Benz.
EU authorities approved the technology in February 2005; the current Mercedes-Benz S-Class model is the first vehicle to be equipped with the new adaptive brake light. Mercedes-Benz will also begin fitting CL-Class coupes with the system in just a few weeks.
The Mercedes experts tested various types of hazard lights for their study. Brake lights that blink four times as rapidly as yellow hazard lights proved to be particularly effective in warning drivers of a possible rear-end collision. The Mercedes study also revealed that activating the hazard lights in dangerous situations had only a minor effect on drivers?????????????????????????????????????? reaction times.
