What safety feature(s) are vehicles equipped with?
- Rollover prevention/mitigation
Most automakers offer an electronic stability control system, and some offer a preparation system (seatbelts tighten, rollbars extend). However, what we’re talking about is more intelligent than that. If the system senses a potential rollover (such as if you whip around a corner too fast or swerve sharply), it will apply the brakes and modulate throttle as needed to help you maintain control. DaimlerChrysler calls it Electronic Roll Mitigation, Ford named it Roll Stability Control, and GM’s is Proactive Roll Avoidance. Range Rover’s is Active Roll Mitigation, while Volvo’s is called the Roll-Over Protection System. But they all have the same goal.
- Occupant-sensitive/dual-stage airbags
All humans are not created equal, and airbags are evolving to compensate in the form of low-risk, multistage and occupant-sensitive deployment. Technology can now sense the different sizes and weights of occupants as well as seatbelt usage, abnormal seating position (such as reaching for the radio or bending to pick something off the floor), rear-facing child seats and even vehicle speed. While driver, passenger and side curtain airbags are nothing new, sensing airbags are popping up (so to speak) everywhere.
- Emergency brake assist/collision mitigation
This brake technology is different from an antilock braking system or electronic brakeforce distribution, in that it recognizes when the driver makes a panic stop (a quick shift from gas to brake pedal) and will apply additional brake pressure to help shorten the stopping distance. It may also work in conjunction with the smart cruise control or stability control system in some vehicles if it senses a potential collision. It is often called brake assist, although BMW, for example, refers to it as Dynamic Brake Control.
- Adaptive headlights and/or night-vision assist
Night vision can be executed in different forms, such as infrared headlamps or thermal-imaging cameras. But no matter the science, the goal is the same: to help you see farther down the road and to spot animals, people or trees in the path — even at nearly 1,000 feet away. An image is generated through a cockpit display, brightening the objects that are hard to see with the naked eye. Adaptive headlights follow the direction of the vehicle (bending the light as you go around corners). They may also be speed-sensitive (changing beam length or height), or compensate for ambient light.
- Rearview camera
Rearview cameras not only protect your car, but also protect children and animals from accidental back-overs. Backing up your car has graduated from side mirrors tilting down or causing chirps and beeps to real-time viewing. New-school tech involves a camera that works with the navigation system to provide a wide-open shot of what’s happening behind you to help with parking or hooking up a trailer.
- Emergency response
There are a variety of ways vehicles now and in the future will handle an emergency situation. For example, DaimlerChrysler’s Enhanced Accident Response System (EARS) turns on interior lighting, unlocks doors and shuts off fuel when airbags deploy, while Volkswagen’s also switches on the hazards and disconnects the battery terminal from the alternator. In addition, GM’s OnStar and BMW Assist both alert their respective response centers of the accident and make crash details available to emergency personnel.
