Abstract: This paper presents a launching performance comparison between three hybrid electric control strategies under maximum acceleration conditions. The result demonstrates viability of the electric launch control approach and is the first known implementation of launch control in a series hybrid electric vehicle (HEV). Experimental data is presented that shows a 0.49 s reduction in initial vehicle motion (IVM) to 60 mph time in the same vehicle and conditions with only the new launching control method engaged. Performance improvements were achieved by using the engine-generator to pre-charge the HV bus which increased bus voltage throughout the test. This novel method generated an IVM-60 mph time of 9.85 s which is 4% faster than the baseline 10.25 s. Test data with electrical and mechanical power system results are presented. Shaft power and energy estimates from the traction motor are evaluated and compared.
