Research on Road Coasting Test of Hybrid Electric Vehicle

Abstract:

On the long straight road of one proving ground of Ministry of Communications, in order to study the influence of brake energy regeneration system (BERS), gear on coasting resistance, road coasting tests of a HEB were carried out under different conditions, separately on and off of BERS, neutral gear and gearing up. Test results showed, the regeneration brake force generated during the process of brake energy regeneration had quadratic relationship with vehicle speed, which had the greatest impact on coasting resistance; Coasting resistance under gearing up increased basically in proportion with rise in vehicle speed, and were about 2200N higher than those under neutral gear. When carrying out HEB road coasting tests, the BERS should be turned off, the transmission should be in neutral gear.
