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.
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.
Vehicle Architecture Review
Review of vehicle dimensions, chassis configuration, passenger layout, access arrangement, emergency exits and principal vehicle systems.
Door & Access Evaluation
Evaluation of door position, entrance geometry, emergency release concepts, passenger circulation, access width and vehicle signal integration.
Seating & Passenger Layout
Review of seat arrangement, aisle width, standing areas, wheelchair spaces, handrails, steps and passenger capacity.
Weight & Axle Load Review
Preliminary weight distribution studies, axle load calculations and evaluation of payload-related engineering risks.
Technical Documentation
Preparation and organization of technical drawings, component information, calculation results, vehicle data and supporting engineering records.
Pre-Approval Risk Review
Identification of missing information, layout conflicts, packaging risks and documentation gaps before official testing begins.
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.
From project information to technical preparation
Each project is reviewed according to its actual vehicle configuration and intended market.
Project Definition
Vehicle category, chassis platform, target market, passenger capacity and approval objectives are defined.
Available Data Review
Drawings, seating layouts, component information, calculations and existing technical documents are reviewed.
Risk & Gap Assessment
Missing information, layout conflicts, component risks and documentation gaps are identified.
Engineering Preparation
Required drawings, calculations, technical tables and project-specific supporting documents are prepared.
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.
