Chamsule Tech Launches First Underground Car Summoning

Commercializing the “Last Mile” of Autonomous Parking

Chamsule Tech, a leading parking information system provider, has officially announced the launch of ‘T-LINKER,’ a smart summon-based service. This innovative system allows users to summon autonomous vehicles directly from underground parking lots to their apartment building entrances. The service addresses a critical gap in current mobility technology by enabling autonomous navigation in GPS-denied environments.

For years, the “last mile” of driving—specifically within complex underground structures—has remained a technological hurdle. While autonomous driving on open roads has advanced significantly, underground parking lots have been blind spots due to the lack of satellite signal reception. Chamsule Tech’s solution bridges this gap, offering a seamless door-to-door experience for residents.

Chamsule Tech

Established in 2005, Chamsule Tech has maintained the top position in South Korea’s parking guidance and smart pass system market. Leveraging its extensive experience in parking infrastructure, the company has developed a solution that integrates vehicle control with building management systems.

The T-LINKER service will begin operations on December 26, 2025. It will initially be deployed in 20 apartment complexes across the nation, covering approximately 13,000 households. This marks the first instance in South Korea where a commercial service successfully navigates a vehicle from a basement parking spot to a resident’s front door without human intervention.

How does it work?

The core of the T-LINKER system lies in its ability to function without GPS. It utilizes a proprietary “Real-Time Spatial Synchronization Technology.” This system synchronizes the vehicle’s location with the building’s digital map in real-time, effectively creating a virtual grid for the car to navigate.

The technology is supported by two key components: Auto-Link Summon (ALS) and Vision-based Summon Grid (V-SG). ALS handles the automated request and routing to the specific building entrance, while V-SG uses visual data to manage the vehicle’s movement and obstacle avoidance within the parking structure. This combination allows the system to guide vehicles like Teslas through complex underground routes where standard navigation fails.

Infrastructure and Scalability

A significant advantage of Chamsule Tech’s approach is its use of existing infrastructure. The company has already installed over 120,000 video and location terminals in 410 apartment complexes nationwide. This pre-established network serves as a foundation for the rapid expansion of the T-LINKER service.

Furthermore, the system is designed to be cost-effective for new developments. Construction projects or housing cooperatives can adopt the autonomous summoning system during the design phase without incurring additional costs. This accessibility suggests that autonomous parking support could soon become a standard feature in modern residential developments.

Future Plans

The service currently supports Tesla vehicles, capitalizing on their native smart summon capabilities. However, Chamsule Tech aims to expand T-LINKER into an open platform compatible with various electric vehicle brands equipped with autonomous driving features.

By allowing residents to control their vehicles through a single mobile application, the company is standardizing the autonomous residential experience. As the service expands beyond the initial 13,000 households, it is expected to fundamentally change how people interact with their vehicles, transforming the underground parking lot from a storage space into an active mobility hub.
