Do Drivers Really Need AEB?
Automatic emergency braking includes a range of systems designed to address the large number of crashes, especially rear-end crashes, in which drivers do not apply the brakes or fail to apply sufficient braking power to avoid or mitigate a crash.
AEB systems use on-vehicle sensors such as radar, cameras or lasers to detect an imminent crash, warn the driver and, if the driver does not take sufficient action, engages the brakes.
Most of you might not know what AEB is and how it works, as each car manufacturer will present its own name for AEB. For example:
- Audi calls it Pre Sense Plus,
- BMW calls it Driving AssistantPlus,
- Ford calls it Active City Stop,
- Honda calls it Collision MitigatingBraking System,
- Infiniti calls it IntelligentBrake Assist,
- Jaguar Land Rover names itAutonomous Emergency Braking
- Peugeot calls it EmergencyCollision Alert with Emergency Braking
- DS calls it Active City Brake
- Hyundai calls it AutonomousEmergency Braking
- Lexus names it Pre-collisionSafety System with Brake Assist,
- Mazda names it Smart City BrakeSupport,
- Mercedes calls it Active BrakeAssist,
- Mini names it City CollisionMitigation,
- Mitsubishi calls it Forward CollisionMitigation,
- Nissan names it IntelligentEmergency Braking,
- Subaru calls it Pre-CollisionBraking System,
- Toyota calls it Pre-CollisionSafety System,
- Volkswagen names it CityEmergency Braking and
- Volvo calls it City Safety
Let us take BMW as an example. BMW providestwo levels of AEB technology with some of its models. BMW Driving Assistant isthe most basic and the most available which is standard across most of itspassenger car and SUV range. As a camera-based system its detection range ismore limited, and will only slow the car and not stop the vehicle if it detectsan obstacle between 10km/h and 60km/h.
Driving Assistant Plus is the more capable version of the system where it uses a radar unit to give it a longer detection range. Able to work from standstill to 210km/h, Driving Assistant Plus will also bring the car to a complete stop when necessary. It is an optional feature on most models, but comes standard on BMW 6 Series, 7 Series, and the M and M50d variants of the X5 and X6.
- The consensus is that AEBreduces crashes.
- AEB is effective in avoidingforward collisions, which are a common type of road crash.
- You cannot rely on AEB to doall your braking; you still need to control your car. AEB engages in emergencysituations and doesn’t work when reversing.
- Inclement weather, fog, sunglare and unlit roads may reduce the camera system’s ability to detect a hazard.
