The parameters matching of the hybrid powertrain system of the hybrid electric vehicle has a directly impact on the performance of the vehicle dynamic and the fuel economy. The preliminary match of the powertrain system base on analysis of Driving Cycle is done, then the software of AVL-Cruise and Matlab are integrated with Isight to optimize parameters of match, by using the Multi-Island GA and NLPQL to establish the combinatorial optimization algorithm. The results show that the fuel economy have been improved by 10.92% without sacrificing the dynamic performance and under the premise of ensuring the limits of the state of charge of battery.

A CAN-Bus protocol analysis and verification method with three key aspects which are static analysis, dynamic analysis and verification &control is put forward. Static analysis ascertains the communication information of each node by bus residual method; Synchronous contrast method is put in use to obtain practical and effective control protocol in the dynamic analysis; Verification &control is to verify the correctness of the analytical protocol and to achieve the control of the critical subsystems by bus gateway system. This scheme has been used to analyze a foreign parallel hybrid powertrain system, and it proves the correctness of the designed static analysis and dynamic analysis, the applicability of verification &control.

Sustainable Power

Long-haul commercial vehicles provide the hotel mode with a desirable comfort cabin for drivers to have rest. During this mode, sustainable power requirement on the on-board battery asks for occasional engine-on/off to maintain the battery SOC level, neither deeply charged nor overcharged. With the conventional engine-only-driven powertrains, there is a great challenge to deliver smooth engine on/off processes during the hotel mode in order to maintain the cabin as quiet and vibrationless as possible. But for the electric hybrid powertrain system, such a challenge can be addressed with the involvement of the hybrid motor/generator (M/G) to achieve smooth engine crank and shutdown. Apparently it is feasible to control M/G to mitigate discomfortable vibrations inside the cabin caused by periodic engine shutdowns for recharging the battery. In this paper, a pole placement control (PPC) with application of the hybrid M/G is developed to dampen out this kind of adverse vibrations which are transmitted from engine/gearbox to the cabin through the chassis structure and cabin mounts. More specifically, the PPC uses the motor speed as a feedback control signal to create a desirable motor torque command so that the vibration transmission could be abated. In the end of this paper, field testing data from a prototype hybrid truck will be presented to demonstrate the effectiveness of this innovative PPC strategy.

Increasing environmental issues and energy crises led to rapid developments of hybrid electric vehicles, especially the planetary hybrid powertrain system (PHPS). This paper presents a comprehensive review of the PHPS, focusing primarily on contributions in the aspect of configuration, classification and comparison. In this work, a new classification method for PHPS architectures is proposed according to the number of electric motors (EMs). In addition, two kinds of PHPS, in the new classification framework, are extensively emphasized in terms of its architectures, advantages and disadvantages. Furthermore, the port diagrams of representative architectures are presented to provide an intuitive method for power flow representation. Finally, a conclusion is made to provide an insight for developing PHPS as well.
