Automobile development and energy transition

(1) Analysis and synthesis of driving cycleDue to the huge amount of collected data, statistical analysis is very complicated. For example, principal component analysis and cluster analysis methods involve multi-dimensional matrix calculations. Therefore, the analysis and processing of data and the construction of driving cycles need to be completed by computers. The tools developed include: … Read More “Analysis, synthesis and verification of electric auto driving cycle” »

Automobile development and energy transition

Characteristic analysis of driving cyclesSome parameters such as vehicle speed, acceleration/deceleration, running time, etc., can be used to reflect the characteristics of the vehicle’s movement on the road. Through the investigation and analysis of these motion characteristics, a driving condition that can represent the motion characteristics is developed. Regardless of whether it is expressed in … Read More “Characteristic Analysis of Driving Cycles” »

Automobile development and energy transition

There are a wide variety of driving cycles in the United States, with different uses, roughly including three systems for authentication (FTP series), research (WVU series) and short-duration (1/M series). Well-known driving cycles such as the Federal Test Program (FTP75), Los Angeles (LA92) and load simulation conditions (1M240). (1) Suitable for driving cycles of passenger … Read More “Driving Cycle for Vehicle Emission Test: Driving Cycle in the United States” »

Automobile development and energy transition

Compared with traditional internal combustion engine vehicles, electric vehicles have no essential difference in the mechanical processes of contact and interaction between the wheels and the ground during driving. The steering, suspension and braking systems of these two vehicles are also basically the same. The main difference between them is the use of different power … Read More “Overview of automobile driving conditions” »
