The "Drive-cycle" basically is the representative of the road. Drive cycles are used to reduce the expense of on road tests, time of test and fatigue of the test engineer. The whole idea is to bring the road to the test lab (a chassis dynamo-meter) or to the computer simulation. Two kinds of drive cycle can be made.
For example, the vehicle computer can identify past driving history as one particular representative cycle (say, FTP-75) and use known information from FTP-75 to improve vehicle performance. This type of control strategy is most useful for hybrid vehicles where the control strategy has a much greater effect on vehicle performance than with a ...
It is also known as FTP-72 or LA-4, and it is also used in Sweden as the A10 or CVS (Constant Volume Sampler) cycle and in Australia as the ADR 27 (Australian Design Rules) cycle. [4] The cycle simulates an urban route of 7.5 mi (12.07 km) with frequent stops. The maximum speed is 56.7 mph (91.2 km/h) and the average speed is 19.6 mph (31.5 km/h).
The regulation took into account various national cycles such as World-wide Heavy-Duty Certification procedure (WHDC) and World-wide Motorcycle Test Cycle (WMTC). [7] It also took into consideration the 1958 Agreement and the 1998 Agreement, those of Japan and the United States Environmental Protection Agency (US EPA) Standard Part 1066.
OBD-II PIDs (On-board diagnostics Parameter IDs) are codes used to request data from a vehicle, used as a diagnostic tool.. SAE standard J1979 defines many OBD-II PIDs. All on-road vehicles and trucks sold in North America are required to support a subset of these codes, primarily for state mandated emissions inspections.
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).
Hierarchy of hazard control is a system used in industry to prioritize possible interventions to minimize or eliminate exposure to hazards. [ a ] It is a widely accepted system promoted by numerous safety organizations.
For the top case, the maximum speed is governed by the assured clear "line-of-sight", as when the "following distance" aft of forward traffic and "steering control" are both adequate. Common examples include when there is no vehicle to be viewed, or when there is a haze or fog that would prevent visualizing a close vehicle in front.
