Vehicle Configuration
Review of vehicle category, intended use, dimensions, mass limits, seating capacity, variants and market configuration.
HOMOLOGATION ENGINEERING · EARLY RISK IDENTIFICATION
Pre-Homologation Risk Review
Early technical review of vehicle designs, components and documentation to identify potential regulatory risks before testing and approval.
REVIEW LOGIC
Critical Risk
May prevent testing or approval
Action Required
Requires evidence or revision
Reviewed
No immediate issue identified
EARLY TECHNICAL REVIEW
Homologation risks should be identified before the vehicle reaches the test stage
Vehicle approval problems frequently originate from decisions made during packaging, structural design, component selection or documentation preparation. When these issues are discovered late, they can cause redesign, repeated testing, additional cost and project delays.
TLG SYSTEMS reviews the available vehicle design and technical documentation before formal testing to identify potential gaps, conflicting information and approval risks requiring action.
01
Testing should confirm the design—not reveal the design strategy
The vehicle configuration, applicable requirements and required evidence should be understood before the official test programme begins.
REVIEW AREAS
Technical areas examined before homologation
The scope is defined according to the vehicle category, approval route, base chassis, conversion level and available project information.
Structural Design
Review of structural modifications, reinforcements, body interfaces, load paths and potential approval implications.
Weight and Axle Loads
Preliminary assessment of vehicle mass, payload, passenger distribution, equipment positions and axle-load margins.
Component Compliance
Review of component approvals, markings, certificates, installation conditions and compatibility with the intended vehicle.
Passenger and Door Areas
Review of entrances, exits, gangways, steps, seating, emergency systems, access dimensions and passenger-safety interfaces.
Technical Documentation
Review of drawings, calculations, approval documents, test reports, component lists and vehicle configuration consistency.
TYPICAL RISK CATEGORIES
Issues that can affect approval timing and test readiness
Each identified issue is recorded with its technical basis, potential project impact and recommended next action.
01
Missing or inconsistent vehicle configuration information
02
Unverified component approvals or incorrect installation conditions
03
Insufficient dimensional clearance or passenger-access compliance
04
Vehicle mass or axle-load margins outside acceptable limits
05
Structural modifications without adequate technical evidence
06
Drawing, calculation and physical vehicle configuration conflicts
07
Missing test evidence, certificates or approval documentation
08
Late design changes affecting previously reviewed systems

Important responsibility statement
TLG SYSTEMS provides preliminary engineering and documentation review support. A pre-homologation review does not constitute official approval, certification or confirmation of compliance. Final assessment, testing, certification and approval remain with the vehicle manufacturer, approval holder, designated technical service and responsible approval authority.
