Park Assist
Park Assist, also known as parking assistance or parking aid, is a technology in modern vehicles designed to assist drivers in parking. It helps by detecting suitable parking spaces and guiding or controlling the vehicle during parking maneuvers
Historical Overview of Autonomous Cars
Since the first invention of the automobile, research has continuously evolved to simplify and secure driving. The concept of autonomous cars emerged in the mid-20th century with experimental prototypes, but it is only recently that these concepts have become tangible realities for the general public.
How does the Park Assist work?
- Sensors: Typically, ultrasonic sensors are installed on the front, rear, and sides of the vehicle. These sensors detect objects and measure the distance to obstacles around the car.
- Cameras: Some systems also use cameras to provide visual guidance and enhance the sensor data.
- Software Algorithms: The data from sensors and cameras is processed by the vehicle’s software, which calculates the best path for parking.
- Control Systems: Depending on the type of park assist, the system can control the steering, acceleration, braking, and gear shifting.
Park Assist Types
- Parking Sensors: Basic park assist systems use sensors to alert the driver with audio and visual cues when approaching obstacles.
- Rearview Camera: Provides a visual feed on the dashboard screen to assist with parking.
- Semi-Automatic Park Assist: The system assists with steering while the driver controls the acceleration and braking.
- Fully Automatic Park Assist: The system takes full control of steering, acceleration, braking, and gear shifting to park the car.
What are the features of park assist?
- Parallel Parking: Assists in parallel parking by finding a suitable space and maneuvering the vehicle into it.
- Perpendicular Parking: Helps in parking perpendicularly by guiding the vehicle into the space.
- Park-Out Assist: Assists the driver in exiting a parking space by guiding the vehicle out safely.
- Surround View System: Provides a 360-degree view around the vehicle to aid in parking.
What does park assist do ?
- Convenience: Simplifies the parking process, especially in tight spaces or crowded areas.
- Safety: Reduces the risk of collisions with obstacles, pedestrians, and other vehicles.
- Precision: Enhances parking accuracy, minimizing the chance of scratches and dents.
Vehicle Models with Park Assist
Many automakers offer park assist features in their vehicles, including:
- Mercedes-Benz: Advanced park assist with remote parking capabilities, see more information below!
- BMW: Parking Assistant Plus with 3D surround view.
- Ford: Active Park Assist for parallel and perpendicular parking.
- Tesla: Autopark feature that automatically parks the car.
Park assist limitations
- Sensor Range: The effectiveness of the system is limited by the range and accuracy of the sensors.
- Environmental Conditions: Adverse weather conditions like heavy rain, snow, or fog can affect sensor performance.
- System Limitations: Not all park assist systems are fully automatic; some require driver intervention.
- Space Requirements: The system needs sufficient space around the vehicle to maneuver safely.
Park Assist on Mercedes-Benz
Now we are going to explore the Mercedes Park Assist, also known as the Parktronic system.
What is the automated parking system process?
1- Recognition of the Parking Space
Using its technological arsenal, the vehicle identifies a suitable space, taking into account its size and surrounding obstacles.
2- Trajectory Calculation
Once the space is identified, the onboard computer calculates the best trajectory to access the spot smoothly.
3- Parking Maneuver
Automated controls take over, adjusting steering, acceleration, and braking to ensure safe and precise parking.
Advantages of Mercedes Autonomous Parking
Driver Comfort
Say goodbye to the stress of tight parallel parking or crowded areas. The system provides a calm and efficient parking experience.
Optimization of Parking Space
Thanks to its precision, the vehicle maximizes the use of space, promoting better organization of parking areas.
Reduction of Accident Risks
By eliminating human errors, the rate of accidents or collisions during maneuvers is significantly reduced.
How do I turn on the park assist ?
To turn on the park assist, there are two methods;
From the Dashboard
An intuitive interface allows easy activation of the parking function, also providing a visual feedback of the ongoing maneuver.
Via a Mobile App
For an even more advanced experience, Mercedes offers the ability to control parking remotely through a dedicated app, allowing the driver to exit the vehicle before the maneuver.
How do I know if my car has parking assist?
To determine if your car has parking assist, you can follow these steps:
1. Check the Owner’s Manual:
The owner’s manual provides detailed information about all the features and systems in your vehicle. Look for sections related to parking assist, park assist, or automated parking systems.
2. Dashboard Indicators:
When you start your car, look at the dashboard for any icons or messages indicating parking assist. These indicators often light up briefly during the startup sequence.
3. Control Buttons:
Check for buttons or switches labeled with symbols or text related to parking assist. Common locations include the center console, near the gear shifter, or on the dashboard. The symbols might depict a “P” with sensors or a car with steering lines.
4. Infotainment System:
Navigate through your vehicle’s infotainment system menu. Many modern cars have a dedicated section for driver assistance features where you can enable, disable, or customize parking assist settings.
5. Exterior Sensors:
Look for parking sensors on your car’s bumpers. These small round or square sensors are usually embedded in the front and rear bumpers and sometimes on the sides.
6. Vehicle Documentation:
Check any sales documentation, window stickers, or feature lists provided when you purchased the car. These documents often list the included features and packages.
7. Ask Your Dealer:
If you are still unsure, contact your dealership. Provide them with your vehicle’s make, model, and VIN (Vehicle Identification Number), and they can tell you if your car is equipped with parking assist.
8. Test It Out:
If you suspect your car has parking assist, try activating it. Usually, engaging reverse gear or pressing the parking assist button will initiate the system, and you may see visual or auditory signals indicating that the system is active.
By following these steps, you can confidently determine if your car is equipped with parking assist.
Park Assist maintenance and Care
- Keep Sensors and cameras Clean: Ensure that sensors and cameras are clean and free from obstructions to maintain accuracy.
- Regular Updates: Ensure the vehicle’s software is up-to-date to benefit from the latest improvements and features.
- Check Functionality: Regularly check that the park assist system is functioning correctly and address any issues promptly.
Regulations and Legislation
Current Legal Framework
The legislation surrounding autonomous vehicles is constantly evolving. Some countries allow their use under certain conditions, while others are still in the analysis phase.
Likely Evolution of Laws
As technology advances and testing increases, there is likely to be a harmonization of regulations, promoting wider adoption of autonomous parking.
Conclusion
Park assist technology significantly enhances the ease and safety of parking by using advanced sensors, cameras, and algorithms to guide or control the vehicle. Understanding the different types of park assist and their benefits can help drivers choose the right system for their needs and make parking a stress-free experience. As automotive technology continues to advance, park assist systems are expected to become more sophisticated and widely available in various vehicle models.
