From Anti-Lock Brakes to Autonomous Braking, ADAS Is Changing How We Drive

Making driving safer with advanced driver-assist programs (ADAS) is nothing new.

Pickup truck manufacturers in the early 1960s began installing a load sensing-proportioning valve to minimize spinouts when braking hard on wet roads. It was nothing more than a metal rod attached to the pickup bed that indicated to the master brake cylinder roughly how much weight the vehicle was carrying, allowing for more efficient braking and decreasing the chances of losing control in an emergency.

To further control brakes from locking under pressure, Chrysler and Bendix developed more sophisticated automatic braking systems (ABS) in the 1970s. This technology, engineered almost 100 years ago in the aircraft industry, controls brake fluid pressure from the master cylinder in response to vehicle load and braking demand—critical when you need to quickly stop (or don’t want your airplane skidding off the runway during landing!) 

From these humble beginnings of traction and braking, comes today’s ADAS, which among other things, monitors the driving scene ahead and if you are getting sleepy.

With studies showing that 21 percent of fatal crashes are due to drivers drifting off to sleep and then drifting off the road, fatigued driver alert systems warn drivers that they are not paying attention. They use different approaches, for example, monitoring steering for sudden corrections or deviations, lane monitoring systems, utilizing a camera for eye and face monitoring, and using artificial intelligence (AI) to learn your normal driving behavior and sensing shifts in these patterns. All these systems alert you when they note fatigue or distraction.

Most people are poor judges of their driving abilities and even worse at noticing when they are inattentive. Forward collision warning (FCW) systems use radar and other advanced technology to detect when your vehicle runs a stop sign, red light, or is in the path of an oncoming vehicle. Some of these systems now also detect pedestrians, cyclists, or even large animals.

Mobileye’s EyeQ technology, for example, detects speed limit signs and controls the high and low headlight beams during night driving. Mobileyepromises that future-generation systems will include camera-only automatic electronic braking, as well as various features enabled by self-driving technologies. 

The U.S. and E. U. mandate that carmakers equip all cars with autonomous emergency braking and forward-collision warning systems by 2022, another in the long line of safety measures such as seatbelts, ABS braking, and airbags.

These systems make collisions less likely, but also have a significant impact on repair. Replacing a bumper or a windshield, for example, is much more complicated (and expensive) when you have to calibrate sophisticated ADAS sensors.
