Investigation on a construction method of driving cycle for tracked vehicle

The simulation based on driving cycle is a new way for tracked vehicle powertrain system matching. Based on the experimental data of a field test, a method for the construction of tracked vehicle driving cycle is proposed. The experimental data is filtered by the wavelet transform method. A circle experimental data is defined as a kinematic specimen. A representative specimen is chosen through the correlation analysis and the speed-acceleration probability distribution analysis. The driving cycle is composed of the speed-time data and altitude-distance data of the representative specimen. The fuel consumption and the output torque of the gearbox in the case of the driving cycle are calculated by AVLCruise simulation software. The difference between the simulated and test fuel consumption values is below 5%. The distributions of the simulated and test data show a similar trend. It is proved that the driving cycle is reasonable and the construction method is feasible.
