TLG SYSTEMS • VEHICLE ENGINEERING

Regulatory Engineering Support

Regulation-aware engineering and technical documentation preparation for bus, minibus, midibus and commercial passenger vehicle projects.

TLG SYSTEMS supports vehicle manufacturers, bodybuilders and conversion companies during the engineering preparation stages preceding official testing and approval. We review vehicle architecture, passenger layout, access systems, weight distribution and technical documentation to identify potential compliance risks before they affect project timing or cost.

01

Technical preparation before official testing and approval

Our work focuses on identifying technical risks, organizing project data and preparing engineering documentation before the vehicle enters the formal approval process.

01

Vehicle Architecture Review

Review of vehicle dimensions, chassis configuration, passenger layout, access arrangement, emergency exits and principal vehicle systems.

02

Door & Access Evaluation

Evaluation of door position, entrance geometry, emergency release concepts, passenger circulation, access width and vehicle signal integration.

03

Seating & Passenger Layout

Review of seat arrangement, aisle width, standing areas, wheelchair spaces, handrails, steps and passenger capacity.

04

Weight & Axle Load Review

Preliminary weight distribution studies, axle load calculations and evaluation of payload-related engineering risks.

05

Technical Documentation

Preparation and organization of technical drawings, component information, calculation results, vehicle data and supporting engineering records.

06

Pre-Approval Risk Review

Identification of missing information, layout conflicts, packaging risks and documentation gaps before official testing begins.

02

Regulation-oriented preparation for passenger vehicles

The applicable regulatory scope is defined according to the vehicle category, target market, chassis platform, passenger capacity and approval strategy.

UN ECE R107 General construction, passenger access, doors, emergency exits, steps, gangways and accessibility preparation.
UN ECE R118 Material information organization and documentation preparation for fire behaviour requirements.
UN ECE R66 Vehicle structure data, body frame inputs and engineering preparation for rollover strength evaluation.
CoC Support Vehicle configuration data and technical information preparation to support Certificate of Conformity workflows.
VECTO Support Collection and organization of available vehicle, component and configuration data for VECTO-related preparation.
COP Support Documentation structure and engineering record preparation to support conformity-of-production processes.
03

From project information to technical preparation

Each project is reviewed according to its actual vehicle configuration and intended market.

01

Project Definition

Vehicle category, chassis platform, target market, passenger capacity and approval objectives are defined.

02

Available Data Review

Drawings, seating layouts, component information, calculations and existing technical documents are reviewed.

03

Risk & Gap Assessment

Missing information, layout conflicts, component risks and documentation gaps are identified.

04

Engineering Preparation

Required drawings, calculations, technical tables and project-specific supporting documents are prepared.

05

Testing Coordination Support

Available technical information is organized to support communication with the selected approval authority or technical service.

Engineering documentation prepared around the real vehicle project

Deliverables are selected according to project maturity, available information and the requirements of the intended approval process.

  • Vehicle technical data review
  • Seating and passenger layout review
  • Door and emergency exit evaluation
  • Weight and axle load calculations
  • Technical drawing package preparation
  • Component and material information tables
  • Pre-homologation risk and gap report
  • Technical service coordination support
Important regulatory position

TLG SYSTEMS is an engineering and manufacturing company. We are not an approval authority or an accredited technical service. Our scope covers engineering review, technical preparation and documentation support before official testing and approval activities performed by the relevant authorized organizations.

Reduce regulatory risk before official testing begins.

Send the available vehicle layout, chassis information, intended market and regulatory targets for an initial technical review.
