Overview of BMW Advanced Car Eye System

BMW’s Advanced Car Eye system is an advanced driver assistance system (ADAS) that provides a range of innovative safety and convenience features. It uses a combination of cameras, radar sensors, and ultrasonic sensors to understand the vehicle’s surroundings in 360 degrees. This environmental data allows the Car Eye system to implement intelligent functions like adaptive cruise control, lane keeping assist, self-parking, collision avoidance, and road sign recognition.

Advanced Car Eye represents the latest iteration of BMW’s driver assistance capabilities. It builds upon past systems but expands the technology further towards semi-autonomous driving. While drivers must remain fully attentive and ready to take control, Advanced Car Eye enables smoother, safer driving by automating some of the more mundane or hazardous aspects.

Some of the key capabilities provided by BMW’s Advanced Car Eye system include:

Assisting with acceleration, braking, and steering to cruise in lane or maintain distance from other vehicles
Recognizing road signs and setting appropriate vehicle speed
Finding open parking spaces and automatically steering into them
Detecting imminent collisions and taking evasive action
Alerting distracted drivers if they drift out of lane or off road
Reading traffic conditions and adjusting cruise control accordingly
Navigating tight turns, exits, highway merges and toll booths

These features demonstrate how Advanced Car Eye aims for more intelligent, human-like driving compared to basic cruise control and lane keeping of past systems. With its comprehensive sensor suite and artificial intelligence, it can handle more complex scenarios. However, BMW stresses that drivers always need to stay alert and engaged, keeping their hands on the wheel. The system is considered Level 2 autonomy, not full self-driving.

Sensors Powering Advanced Car Eye

Advanced Car Eye would not be possible without its array of high-tech sensors continuously monitoring the road. BMW uses a combination of cameras, radar, and ultrasonic sensors to achieve 360 degree environmental awareness. Let’s take a closer look at each:

Cameras

12 cameras in total around the vehicle
Front and side cameras monitor road conditions
Rear view camera aids with parking/reversing
Interior camera detects driver attention/distraction

The 12 cameras provide overlapping, panoramic vision around the entirety of the vehicle. Having redundant perspectives on all sides ensures critical driving areas are continually observed from multiple angles. The cameras have high dynamic range and quality to function in challenging lighting conditions like driving at night or towards sun glare. Real-time video feeds are processed by an onboard computer using machine vision algorithms to identify road markings, read signs, detect objects, and more.

Radar Sensors

5 radar sensors around front and sides
Radar provides accurate range and speed data
Ultrasonic fills in blind spots

To complement the cameras, BMW also equips Advanced Car Eye vehicles with radar technology. This provides precise measurements of distance to and velocity of surrounding objects using radio waves. Having accurate range and speed data is crucial for functions like adaptive cruise control so the vehicle smoothly adjusts speed to maintain a safe gap. The radar sensors have wide fields of view to continuously track multiple vehicles ahead. BMW strategically places radar units around the front and sides of the vehicle to enable long range detection without blind spots. Short range blind spots are covered by…

Ultrasonic Sensors

12 ultrasonic sensors around bumpers
Detect objects within 2-3 meters
Aid parking and low speed maneuvering

Rounding out the sensor suite are 12 ultrasonic sensors located in the bumpers. As the name implies, these use sound waves to identify objects within a few meters of the vehicle. This makes them ideal for maneuvering in parking lots, handling tight turns, and other low speed situations. The ultrasonic sensors provide close range awareness that cameras and radar miss. Together, the cameras, radar, and ultrasonic sensors give Advanced Car Eye a detailed, real-time view of the full driving environment. This sensor fusion enables advanced capabilities not possible with past driver assistance systems.

Key Driver Assistance Features Enabled By Car Eye

The sensors allow Advanced Car Eye to implement intelligent driver assistance across a range of scenarios. While always requiring driver supervision, the system provides smoother, safer driving in situations from highway cruising to parking. Let’s look at some of the key features:

Lane Keeping Assist

Lane keeping assist uses the front cameras to detect road lane markings. If you start drifting out of your lane unintentionally, perhaps distracted or drowsy, Advanced Car Eye will apply subtle corrective steering to keep the vehicle centered. This helps avoid dangerous lane departures or collisions from leaving the roadway. The system works equally well on straight and curved roads. Advanced Car Eye processes lane lines, shoulder edges, and adjacent vehicles to calculate the proper trajectory.

Adaptive Cruise Control

Standard cruise control only maintains a set speed. BMW’s Advanced Car Eye takes it to the next level with adaptive cruise. Using radars and cameras, it adjusts your speed to keep a safe distance from vehicles ahead. If traffic slows, Car Eye will smoothly decelerate in sync. When the lane clears again, it re-accelerates back to the set speed. This makes driving in varying traffic flow much easier and reduces driver workload. The system works in stop-and-go congestion too, coming to a complete stop then resuming automatically when possible.

Collision Avoidance

Sensors on all sides of the vehicle allow Car Eye to detect potential collisions and take action. Whether a vehicle suddenly brakes ahead or pedestrians step into your path, the system alerts the driver and can even automatically brake in an emergency if the driver does not respond. This can prevent accidents or reduce collision impact, especially useful if the driver is distracted or reacting slowly. Advanced Car Eye considers relative speeds and trajectories of road users in all directions, not just directly ahead like basic systems.

Self Parking

Parallel parking and backing into tight spots can be challenging. Advanced Car Eye takes the stress out by handling the steering during parking. The driver simply needs to operate the gas and brake. Once engaged, the system will identify viable spots, alert the driver, and park itself hands-free. The ultrasonic sensors guide smooth, precise maneuvering into place. This makes parking in busy lots and cities effortless.

Traffic Sign Recognition

Recognizing speed limits, stop signs, and other road signs is an important capability provided by the front cameras. Car Eye uses machine vision to quickly read posted speed limits and adjust your vehicle accordingly. It also alerts you of upcoming stop signs, temporary traffic controls like construction zones, and other regulatory signs. This heightens awareness and safety since drivers can easily miss signage details while focused on the road. Having the vehicle automatically adjust to the proper speed frees up mental workload too.

The wide range of functionality enabled by Advanced Car Eye adds to driving ease and takes stress off the driver. Whether it’s staying centered in lane, adapting speed to traffic, finding parking spaces, or monitoring signs, the system uses environmental sensors and AI to handle mundane tasks. This leaves the driver to focus on the big picture. However, BMW emphasizes that drivers always need to remain alert and never treat the vehicle as fully autonomous.

How Car Eye Enables Semi-Autonomous Driving

The comprehensive capabilities packed into BMW’s Advanced Car Eye system represent a major step towards autonomous driving. It provides level 2 autonomy, meaning it can steer, accelerate, and brake automatically in certain scenarios but requires human oversight at all times. How exactly does Car Eye take automated driving a level beyond past driver assistance features?
