Automated Valet Parking Systems (AVPS) represent a significant evolution in how vehicles are stored and managed within parking facilities, particularly in the context of “smart garages.” These systems leverage a combination of sensors, software, and automated vehicle control to navigate and park vehicles without direct human intervention during the parking process. The underlying principle is to remove the driver from the immediate act of parking, allowing a central system to orchestrate the efficient and safe allocation of parking spaces.
The development of AVPS is driven by several factors, including the increasing demand for parking in urban environments, the desire to maximize parking efficiency, and the broader push towards automation in various sectors. As urban populations grow and car ownership remains prevalent, finding and utilizing parking spaces efficiently becomes a persistent challenge. AVPS aim to address this by not only automating the parking maneuver itself but also by optimizing space utilization within the garage.
System Architecture and Components
An AVPS is a complex interplay of hardware and software, designed to act as the brain and nervous system of the smart garage. It’s not simply a robot; it’s a coordinated effort between various technological elements.
Sensing and Perception
The first, and arguably most critical, stage of any AVPS is understanding its environment. This is akin to how a human driver uses their eyes and ears to navigate.
LiDAR and Radar Sensors
These sensors provide the system with crucial data about the surrounding environment, including the presence of obstacles, walls, other vehicles, and pedestrians. LiDAR (Light Detection and Ranging) uses laser pulses to measure distances and create a 3D map of the surroundings, while radar uses radio waves. Together, they form a robust perception suite capable of operating in varying light and weather conditions, though each has its strengths and weaknesses. LiDAR excels at high-resolution mapping, while radar can penetrate fog and rain more effectively.
Ultrasonic Sensors
These sensors are typically used for short-range detection, particularly for objects immediately adjacent to the vehicle or the parking infrastructure. They emit sound waves and measure the time it takes for the echo to return, providing distance information. Think of them as the system’s “proximity alert” system, helping to avoid low-speed bumps and scrapes.
Cameras and Computer Vision
Cameras play a vital role in identifying lane markings, traffic signs, and other visual cues within the parking facility. Advanced computer vision algorithms process the camera feed to classify objects, track their movement, and understand the context of the environment. This allows the system to interpret complex scenarios, such as reading a “pull forward” sign or identifying a designated drop-off zone.
Localization and Mapping (SLAM)
For the system to know where it is and where it needs to go, accurate localization and mapping are essential. This isn’t just about knowing which floor you’re on, but centimeter-level precision.
Inertial Measurement Units (IMUs)
IMUs, composed of accelerometers and gyroscopes, measure the vehicle’s acceleration and angular velocity. This data provides an estimate of the vehicle’s position and orientation, even in areas where GPS signals are unavailable, such as underground parking garages. They act as the vehicle’s internal sense of motion.
Wheel Encoders
These sensors measure the rotation of the vehicle’s wheels, allowing for dead reckoning – calculating position based on known starting points and motion. Combined with IMU data, they help the system track its movement over time.
High-Definition (HD) Maps
AVPS rely on detailed, pre-generated maps of the parking facility. These maps go beyond traditional navigation maps, containing precise information about lane boundaries, pillar locations, parking bay dimensions, and even the exact positions of charging stations or reserved spots. They provide the AVPS with a ground truth, a detailed blueprint of its operational area.
Vehicle Control and Actuation
Once the system perceives its environment and knows its location, it needs to be able to physically maneuver the vehicle.
Steering, Braking, and Acceleration Control
AVPS interface with the vehicle’s drive-by-wire systems to control steering, braking, and acceleration. This allows for precise and smooth execution of parking maneuvers. Unlike human drivers who might over- or under-steer, or brake too sharply, the AVPS can execute commands with robotic precision.
Automated Parking Modules
In some systems, especially those requiring higher levels of autonomy or retrofitting into existing garages, specialized automated parking modules might be integrated. These can include robotic arms or platforms that physically move vehicles into and out of parking bays. These act like mechanical assistants, capable of precise movements.
Communication and Networking
The coordination of multiple vehicles and an intelligent parking infrastructure relies on a robust communication network.
Vehicle-to-Vehicle (V2V) Communication
V2V communication allows vehicles within the system to share information about their position, speed, and intended maneuvers. This helps to prevent collisions and optimize traffic flow within the garage. Imagine vehicles “talking” to each other, coordinating their movements to avoid conflicts, like a well-rehearsed dance.
Vehicle-to-Infrastructure (V2I) Communication
V2I communication enables vehicles to interact with the parking infrastructure itself, receiving information about available parking spaces, lane restrictions, or system status updates. This is like the garage “whispering” directions and information to the vehicles.
Central Management System
A sophisticated central management system is the orchestrator of the entire AVPS. It receives data from all vehicles and sensors, processes it, and sends commands back to the vehicles. This is the conductor of the orchestra, ensuring every instrument plays its part in harmony. It also handles user requests, manages parking bay assignments, and monitors the overall system health.

Operational Workflow and User Experience
The process of using an AVPS is designed to be seamless and intuitive for the user. It aims to reduce the stress and time associated with traditional parking.
Vehicle Drop-off and Handoff
The user experience begins when the driver enters the smart garage and proceeds to a designated drop-off area.
Designated Drop-off Zones
These are clearly marked areas where the driver can safely exit their vehicle. The AVPS takes over at this point. The driver hands over the vehicle to the system, much like handing over keys to a human valet, but without the human element.
Handoff Protocol
A clear protocol ensures a smooth transition of control from the driver to the AVPS. This might involve a simple button press or a voice command, confirming the driver’s intention to relinquish control. The system then confirms it’s ready to accept the vehicle.
Automated Parking and Retrieval
Once the vehicle is in the system’s care, the magic of automation unfolds.
Space Allocation and Navigation
The central management system identifies an available parking space based on various factors, including vehicle size, charging needs (if applicable), and optimal spatial distribution. The AVPS then navigates the vehicle to that spot, utilizing its sensors and map data. The system is like a highly efficient librarian, knowing exactly where every book (car) should go.
Maneuvering and Parking
The AVPS performs the precise steering, braking, and acceleration required to maneuver the vehicle into the designated parking bay. This can involve complex multi-point turns or precise parallel parking, executed with a level of consistency that human drivers often struggle to achieve.
Vehicle Retrieval Request
When the user wishes to retrieve their vehicle, they typically do so through a mobile application or an interface within the parking facility. This initiates a request to the central management system.
Automated Retrieval Process
The AVPS then brings the vehicle from its parking bay to a designated pick-up zone, again navigating through the garage automatically. The driver is alerted when their vehicle is ready. The system orchestrates the return journey, ensuring the vehicle is waiting without unnecessary delays.
User Interface and Engagement
The interaction between the user and the AVPS is crucial for trust and convenience.
Mobile Application Integration
Mobile apps are a common interface, allowing users to book parking, track their vehicle’s status, request retrieval, and even make payments. This puts the control and information in the palm of the user’s hand.
In-Garage Terminals and Displays
Interactive terminals and digital displays within the garage provide real-time information about parking availability, system status, and instructions for users. These offer an alternative for those who may not use a mobile app.
