to it for result purpose. And the total duration of the test was 200s and all the parameters such as engine 
power, battery power, electric power, speed of engine and the electric motor, fuel consumption, etc. 
were determined by different sensors connected to each component of the simulation. 
According to some research [3],[4],[5], the comparison between the Parallel Hybrid electric vehicle 
(PHEV) and the conventional ICE Vehicles (ICEV) were made by collecting the data for every 
parameter in real world driving of both the vehicle type PHEV and ICEV and compare them. The 
Software use here was known as Autonomie. the simulation was done on several driving conditions and 
many real-life parameters were also measured such as weather conditions, accessories load, road pattern, 
vehicle activity (driving cycle), and engine capability and also fuel economy, emissions, and all 
equipment performance were evaluated. The standard driving cycles which were used are FTP, UDDS, 
and US06HWY. According to results, the fuel economy of PHEV was increased up to 68% in real 
driving condition than the ICEV the reason was due to regenerative braking which was used 
continuously in city due to which the CO2 and other harmful gas emission decreased up to 40% due 
using electric mode during less performance required by the vehicle generally in the city traffic. Another 
benefit was for ECU which can change the power source unit according to required performance, which 
lead to increase in engine performance by 12% in real world driving cycle whereas in FTP it was 30%.
