Door System Integration Engineering

Vehicle-level integration support for electric door mechanisms, control units, emergency systems and passenger entrance layouts.

A reliable vehicle door system requires more than selecting a mechanism. Door geometry, body structure, entrance steps, passenger flow, electrical signals, emergency operation, sealing, installation tolerances and service access must be evaluated as one complete engineering package.

01
ENGINEERING SCOPE

The door, entrance and vehicle body must work as one system

Door system integration begins with the real vehicle architecture. The selected solution must fit the available body space, achieve the required clear opening and operate safely throughout the expected vehicle service life.

01

Door Aperture Evaluation

Review of entrance width, height, body opening, structural zones and available mechanism installation space.

02

Mechanism Packaging

Positioning of mechanisms, shafts, arms, actuators, brackets and moving components inside the available body structure.

03

Door Leaf Geometry

Evaluation of door dimensions, movement path, body curvature, sealing surfaces, clearances and external appearance.

04

Passenger Entrance Layout

Coordination of the door opening with steps, wheelchair access, handrails, aisle geometry and passenger movement.

05

Electrical Integration

Definition of voltage, control unit configuration, wiring, vehicle signals, warning outputs and safety inputs.

06

Emergency Operation

Integration of internal and external emergency release components with practical access and mechanical routing.

02
COMPLETE SYSTEM

Mechanical, electrical and structural interfaces

Each interface is reviewed together to reduce installation conflicts, uncontrolled tolerances and late-stage design changes.

Vehicle Body Door aperture, structural posts, roof area, floor structure and reinforcement zones.
Door Mechanism Mechanism position, shaft arrangement, linkages, arms, pivots and movement geometry.
Electric Actuation Actuator or motor selection, mounting position, mechanism ratio and operating speed.
Door Control Unit Control logic, vehicle inputs, warning outputs, anti-pinch functions and emergency signals.
Door Leaf & Sealing Frame geometry, glazing, seals, closing pressure, exterior alignment and water management.
Passenger Area Step arrangement, handrails, entrance lighting, accessibility and usable clear opening.
Emergency Components Internal and external controls, mechanical routing, accessibility and reset procedure.
Service Access Adjustment points, removable panels, wiring access, component replacement and maintenance requirements.
03
CONTROL & SAFETY INTERFACES

Door control functions matched with the vehicle architecture

Available control and safety functions are selected according to the door system, ECU configuration and vehicle project.

12V / 24V DC Operation Electrical configuration according to the vehicle voltage.
Door-Open Warning Warning output for the driver or vehicle control system.
Vehicle Speed Signal Support for project-specific speed-related door logic.
Parking Brake Interface Configurable door logic using the available parking-brake signal.
Anti-Pinch Logic Motor-current monitoring and external safety input options.
Sensitive Edge Input Compatibility with external obstacle-detection components.
Emergency Signal Input Emergency status information according to system configuration.
End-of-Stroke Control Controlled movement near opening and closing positions.
04
WORKFLOW

From entrance requirement to production preparation

The integration process is organized around real vehicle data, installation constraints and intended operating conditions.

01

Project Information Review

Vehicle drawings, body dimensions, entrance targets, electrical architecture and market requirements are reviewed.

02

Door System Selection

Single-leaf, double-leaf or sliding-door architecture is evaluated according to the project.

03

Packaging & Movement Study

Mechanism location, door movement, structural interfaces and required clearances are defined.

04

Electrical Interface Definition

ECU configuration, wiring, vehicle signals and safety interfaces are documented.

05

Prototype Installation Support

Installation points, adjustment requirements and prototype feedback are reviewed.

06

Production Preparation

Final installation information, component scope and technical documentation are organized for production.
