Electronic Control Units for Electric Door Systems
TLG SYSTEMS door control units are developed for electric bus, minibus and commercial passenger vehicle door systems. The control unit manages door movement, vehicle signal integration, anti-pinch protection, emergency inputs, warning outputs and automatic closing logic according to the selected door configuration.
One control unit platform, configured according to door system requirements.
The control unit can be configured for single-leaf, double-leaf and sliding electric door systems. Final operating mode, input/output configuration and vehicle interface details are defined according to the door type and vehicle project.
Single-Leaf Door Control Unit
Developed for outward opening single-leaf electric door systems. It manages actuator movement, end-position behaviour, safety inputs, emergency signals and vehicle interface functions for single-leaf bus and minibus door applications.
Double-Leaf Door Control Unit
Developed for outward opening double-leaf electric door systems. It supports door movement control, safety logic, warning outputs, emergency signal input and vehicle integration functions for wider passenger entrance systems.
Sliding Door Control Unit
Developed for electric sliding door systems used in bus, minibus and special passenger vehicle projects. It manages controlled sliding movement, safety functions, end-position behaviour, emergency inputs and vehicle signal integration.

Designed for integration with vehicle electrical architecture.
The control unit is not only a motor driver. It is part of the door system interface. It receives vehicle and safety signals, manages automatic closing logic and provides outputs required for warning and integration functions.
- Vehicle speed signal input for 3 km/h logic
- Parking brake signal input for automatic closing logic
- Emergency signal input
- Door open warning lamp output
- Tachograph connection support
- External anti-pinch input support
Configured according to single-leaf, double-leaf or sliding door operation.
The same control unit family is positioned for different door system requirements. The final control logic is selected according to the mechanism, motor, emergency release architecture and vehicle signal strategy.
Single-Leaf Mode
Suitable for outward opening single-leaf electric door mechanisms with lift-and-lock style movement, end-position behaviour, anti-pinch logic and vehicle signal integration.
Double-Leaf Mode
Suitable for outward opening double-leaf electric door systems where wider entrance operation, emergency logic, warning output and vehicle interface support are required.
Sliding Door Mode
Suitable for electric sliding door mechanisms where controlled sliding movement, end-position braking, safety input and vehicle signal logic must be configured according to the project.
Developed with vehicle electrical integration in mind.
The control unit design is developed with vehicle electrical integration, EMC requirements and interface responsibility management in mind. For OEM and Stage-2 vehicle projects, cybersecurity-related interface responsibilities can be defined project by project through the relevant vehicle integration agreement.
- Vehicle electronics compatible control approach
- Project-specific input/output definition
- Electrical interface responsibility can be defined with the vehicle integrator
- Suitable for OEM and Stage-2 vehicle project discussions
- Final validation depends on vehicle platform and system configuration
