The WLTP replaces the old NEDC as the European homologation lab-bench procedure, which was established in the 1980s to simulate urban driving conditions for a passenger car. [8] In 1992 the NEDC was updated to also include a non-urban path (characterized by medium to high speeds), and finally in 1997 CO 2 emission figures were added, too. [ 9 ]
Rather than a UN-style system of type approvals, the US and Canadian auto safety regulations operate on the principle of self-certification, wherein the manufacturer or importer of a vehicle or item of motor vehicle equipment certifies—i.e., asserts and promises—that the vehicle or equipment complies with all applicable federal or Canada ...
Motor vehicle type approval is the method by which motor vehicles, vehicle trailers and systems, components and separate technical units intended for such vehicles achieve type approval in the European Union (EU) or in other UN-ECE member states. There is no EU approval body: authorized approval bodies of member states are responsible for type ...
This resulted in the 1958 Agreement on uniform conditions of approval and mutual recognition of vehicle approvals, components, and parts. This was one of the first international agreements on vehicle regulation, which initially focused on European countries. The European Union played a role in harmonizing regulations between member states.
The European Commission intends to introduce a type approval procedure to measure the energy efficiency of mobile air conditioning systems in vehicles, as well as its effect on fuel consumption and emissions, and display an efficiency label on the vehicle; the work is being performed by TU Graz (Institute for Internal combustion engines and ...
Vehicle type approval is the confirmation that production samples of a design will meet specified performance standards. [4] Traditionally, there are two systems of type approval in Europe. The first one is based on the EC directives and regulates the approval of whole vehicles, vehicle systems, and separate components.
The China Light-Duty Vehicle Test Cycle (CLTC) (Chinese: 中国轻型汽车行驶工况; pinyin: Zhōngguó qīngxíng qìchē xíngshǐ gōng kuàng) is a driving cycle standard introduced by the government of China to measure the energy consumption, driving range and emissions of light-duty vehicles, including both internal combustion engine (ICE) vehicles and electric vehicles (EV).
The procedure involves instrumentation of the test vehicle to collect information while driving on the test road. There are two major types of data to be collected, Driver Behavior data and Vehicle versus Road data. The Vehicle versus Road data are used to prepare the road drive cycle and the Driver Behavior data to prepare the Driver model.
