How It Works
GNSS Positioning
You use global navigation satellite systems to find your vehicle’s spot. These systems, like the global positioning system, have many satellites in space. The satellites send signals down to your vehicle. Your receiver in the vehicle picks up these gnss signals. It figures out your location by timing how long the signals take to reach you. This gives you real-time positioning. Real-time positioning is important for digital signage triggers.
In open places, standard positioning is accurate within 3 to 5 meters. In cities with tall buildings, signals can bounce or get blocked. This makes positioning less exact. Advanced methods, like shadow matching and high-definition GNSS, help a lot. They mix satellite signals with visual sensors and digital maps. These methods can make positioning accurate to 10-20 centimeters, even in busy cities. Shadow matching uses 3D city models to guess which signals should reach your vehicle. It checks this against the signals your vehicle actually gets. This helps fix mistakes and lets your navigation system know your spot.
The chart shows that advanced positioning, like Real-Time Kinematic (RTK), is more accurate in cities than standard GNSS. But these systems can cost more money and might not work everywhere.
Note: Good positioning needs strong, clear signals. Tall buildings, tunnels, or bad weather can block or bounce signals. This makes it harder for your system to know your exact spot.
Data Communication
Your vehicle’s navigation system does more than just get signals. It also needs to share and update information fast. As your vehicle moves, sensors like cameras, LiDAR, and IMUs collect data about what’s around you. The onboard computer looks at this data right away. It matches the data with digital maps to check your position and spot changes.
Here’s how the data communication process works:
Step/Component | Description |
|---|---|
Sensors | Vehicles use GNSS (high-precision RTK mode ~20 cm accuracy), cameras, LIDAR, IMU, radar for environment sensing. |
Onboard Processing | Real-time semantic segmentation, SLAM, and vectorization of perception data performed on high-performance computing platforms. |
Map Matching | Vectorized perception data is matched against pre-existing HD maps to detect unchanged and new map elements. |
Crowdsourcing Data Upload | Raw data, keyframes, or recognized results are uploaded to the cloud to optimize bandwidth and processing. |
Cloud Aggregation | Crowdsourced data from multiple vehicles is aggregated and processed in the cloud to update HD maps dynamically. |
Map Update Distribution | Updated HD map packages are pushed back to vehicles, enabling real-time map content updates as vehicles traverse GNSS-defined zones. |
This system keeps your vehicle’s navigation and digital signage up to date. AI-powered maps use real-time data from many vehicles, sensors, and satellites. These maps change as you drive. They show new traffic, road work, or weather. Your vehicle gets these updates and uses them to change navigation and digital content.
Tip: Fast data sharing means your digital signage always shows the newest and best information as you travel.
Content Triggering
Once your vehicle knows its spot, the system uses this to trigger digital signage. The logic often uses geofencing. Geofencing sets up invisible lines around real places. When your vehicle enters or leaves these zones, the system shows certain digital content.
For example, if your bus gets close to a shopping area, the system finds your spot using gnss signals. It then shows an ad for a nearby store on the screen. If your train is near a station, the system shows arrival times or safety alerts. The system can also use beacons, like Apple’s iBeacon or Google Eddystone, to trigger content based on your exact spot.
To make these triggers work well, your vehicle’s system uses data from many sensors. High-precision GNSS, IMUs, and LiDAR all work together. Sensor fusion algorithms, like Kalman filters, mix these data sources. This helps your system keep good positioning, even when signals are weak or blocked. Advanced algorithms also figure out your vehicle’s direction. This way, the digital signage always matches your movement.
You get the right digital content at the right time because of this technology. The system updates by itself as you move through different zones. This makes your ride more helpful and interesting.
System Components
