Abstract
In this study, the performance of a low-floor midsize bus under development is predicted through simulations. To predict the vehicle’s acceleration, maximum speed, and uphill driving performance, a forward simulator which calculates the vehicle power is developed. Also we verify the forward simulator by comparing simulations and test result for benchmarking vehicle. To predict the fuel consumption, we use a backward simulator for a specified road cycle. However, to predict the fuel consumption using the backward simulation the engine fuel-consumption map is needed. The engine fuel-consumption map extracting data from a similar sized diesel engine is used by re-scaling the maximum torque. As a result, we simulate the vehicle’s forward performance with a new engine. Further, we simulated the backward performance to optimize the fuel efficiency and gearshift timing.
