Regenerative braking control strategy in mild hybrid electric vehicles equipped with automatic manual transmission

QIN Datong, YE Ming, LIU Zhenjun

Frontiers of Mechanical Engineering 2007, Volume 2, Issue 3,   Pages 364-369 doi: 10.1007/s11465-007-0064-0

Abstract: The actual regenerative braking force of an integrated starter/generator (ISG), which is varied with desired braking deceleration and vehicle speed, is calculated based on an analysis of the required deceleration, maximum braking force of ISG, engine braking force and state of charge (SOC) of battery. Braking force distribution strategies are presented according to the actual regenerative braking force of ISG. To recover the vehicle s kinetic energy maximally, braking shift rules for a mild hybrid electric vehicle (HEV) equipped with automatic manual transmission (AMT) are brought forward and effects of transmission ratios are considered. A test-bed is built up and regenerative braking tests are carried out. The results show that power recovered by the braking shift rules is more than that recovered by the normal braking control rules.

Noise reduction for centrifugal fan with non-isometric forward-swept blade impeller

MA Jianfeng, QI Datong, MAO Yijun

Frontiers in Energy 2008, Volume 2, Issue 4,   Pages 433-437 doi: 10.1007/s11708-008-0082-6

Abstract: To reduce the noise of the T9-19No.4A centrifugal fan, whose impeller has equidistant forward-swept blades, two new impellers with different blade spacing were designed and an experimental study was conducted. Both the fan’s aerodynamic performance and noise were measured when the two redesigned impellers were compared with the original ones. The test results are discussed in detail and the effect of the noise reduction method for a centrifugal fan using impellers with non-isometric forward-swept blades was analyzed, which can serve as a reference for researches on reduction of fan noise.
