Development of Muar Driving Cycle Based on Real-World Driving Conditions

Abstract

A driving cycle is a graph that represents vehicle speed over time of a
specific area and characterizes a typical driving pattern for a city's population at
different driving conditions such as peak and off-peak. This research aims to design
and develop Muar Driving Cycle (MDC) based on the actual driving condition.
Selection of routes made via Google Traffic based on the congestion level and driving
conditions for urban, semi-urban and rural areas in the Muar district. The data was
collected using the test vehicle Proton Saga 1.3L CVT, equipped with the data logger
system. Recording data has been segregated according to the maximum vehicle speed
for each micro-trip. Micro-trips were combined to construct the Muar Driving Cycle
based on target speed and acceleration. The initial driving pattern of MDC has been
developed and the cycle characteristic are presented. The results obtained are
compared with the current driving cycle including NEDC, WLTC and the MUDC.
MDC has the high velocity with an average of 40.66 km/h with a maximum speed of
112.06 km/h and average acceleration of 0.263 m/s2 . The drive cycle should be
validated through vehicle simulation and the chassis emission cycle test in the future.
The findings from the study would benefit in identifying the optimum solution for
powertrain and vehicle technologies for Malaysian driving conditions.
