Project Requirement & Technical Target Definition
Before starting vehicle layout, CAD design or homologation preparation, the project must be clearly defined. TLG SYSTEMS supports bodybuilders and vehicle manufacturers in converting commercial targets, chassis data, passenger capacity requirements and regulatory obligations into a clear technical project brief.
What we define at the beginning of the project
The target definition phase creates the technical foundation for the full vehicle development process. It reduces design revisions, clarifies constraints and aligns engineering decisions with market, regulatory and production requirements.
Vehicle Application & Market Target
Vehicle class, target market, operating profile, customer use case, seating capacity and commercial positioning.
Chassis & Platform Data Review
Wheelbase, GVW, front/rear axle limits, chassis restrictions, OEM bodybuilder data and packaging constraints.
Passenger Layout & Access Targets
Seating arrangement, wheelchair area, entrance geometry, step layout, aisle clearance and passenger flow.
Door System & Entry Requirements
Door type, clear opening target, mechanism packaging, emergency release concept and control interface needs.
Weight & Axle Load Targets
Preliminary weight targets, axle load balance, luggage/load assumptions and critical mass distribution limits.
Regulatory & Homologation Scope
Target regulations, R107/R118 scope, COC preparation needs, VECTO data requirements and approval strategy.
Typical outputs of this phase
At the end of the target definition phase, the project becomes measurable, traceable and ready for layout, body engineering and homologation preparation.
