Building a Yoma Car Share system requires precise integration between hardware setup, embedded firmware, telematics devices, and cloud platforms. Our emulator capabilities include:
- Vehicle access control
- Real-time GPS tracking
- CAN bus data monitoring
- Driver authentication (RFID/Bluetooth/Wi-Fi Internet Access)
- Safety logic and usage analytics
Each component must behave exactly as it would in a real vehicle.
Yoma Car Share Emulator: Built for Real-World
Yoma Car Share Emulator acts as a real telematics-driven Yoma Car Share vehicle while using production-grade telematics and GPS hardware.
It enables end-to-end system testing and real demonstrations without the need to deploy a physical car.
Our engineering team designed the emulator to mirror real vehicle behavior using the same architecture used in production car-share deployments.
Core System Components
- MCU-Based Emulator Controller
- Touch Screen Vehicle HMI
- Miniature Physical Car Model
- GPS & Telematics Device
- Yoma InnoSights Fleet Platform
Each layer plays a direct role in building real Car Share vehicle behavior.
Understanding MCU: What is it?
At the core of the emulator is a high-performance Microcontroller Unit (MCU). The MCU is selected for its ability to support:
- Multiple UART and GPIO interfaces
- CAN bus communication
- Real-time data generation
- Long-running operational reliability
- GPS device communication
Within the emulator, the MCU firmware, acts as a virtual ECU and, is responsible for generating realistic CAN bus frames, simulating GPS location, movement, and speed, managing Yoma Car Share vehicle state logic and synchronizing UI actions with telematics data.
All vehicle behaviors within the emulator originates from the MCU firmware.
Touch Screen HMI: Interactive Controls
The emulator features a touch screen HMI that allows users to interact directly with the simulated vehicle.
Users can simulate actions such as:
- Starting the engine
- Opening or closing doors
- Changing vehicle speed
- Adjusting fuel levels
- Changing the vehicle’s location
Each action immediately updates the vehicle’s state machine and triggers the corresponding CAN and GPS data updates, keeping the system consistent across the UI, firmware, telematics device, and cloud layers.
This coordinated behavior produces production-accurate Yoma Car Share data flow.

Actionable Vehicle Model
The emulator’s car model is designed to respond to all actions triggered through the Touch Screen HMI. When a user performs an action, the system updates the vehicle state.
Vehicle parameters and CAN data profiles are configurable. The same model can also represent different vehicle types for testing across multiple car models.
GPS & Custom Telemetry Simulation
1. GPS Movement Simulation
The emulator integrates GPS simulation to replicate realistic vehicle movement and location data.
It generates GPS information such as:
- Latitude and longitude
- Vehicle speed and direction
- Stop and movement states
With this simulated GPS data, the system can reproduce real Yoma Car Share scenarios, including:
- Starting a trip from a rental hub
- Driving along a route
- Ending a trip outside the rental hub
- Ending a trip inside the rental hub
This allows location-based features and trip flows to be tested just as they would occur in a real vehicle.

2. Custom Telemetry Parameters
In addition to GPS data, the emulator also transmits engine status, door states, and other vehicle events. All data is sent to Yoma InnoSights without any logic changes, mirroring the same data flow used in real vehicles.
The GPS and telematics device acts as the production bridge between the emulator and the cloud. It supports RFID driver identification, CAN bus data ingestion, GPS and custom telemetry forwarding, and secure communication with Yoma InnoSights.
By using a real telematics device, the emulator maintains identical logic between simulation and production vehicles.
