The paper presents a mode shift control strategy of dual-mode power-split hybrid electric vehicle during the mode shift phase, intended to reduce the torque variation in the driveshaft and improve the shift quality. To evaluate the shift characteristics of this power-split hybrid electric vehicle, the detailed dynamic models are developed. Based on the dynamic models, a mode shift performance simulator...
Along with the development of hybrid electric vehicle, dual-mode electro-mechanical transmission (EMT) as an innovative power-split transmission technology, is widely applied in heavy-load vehicles. In this paper, a dynamic model for a dual-mode EMT based hybrid electric vehicle is developed which consists of two electrically variable transmission (EVT) modes and provides a platform for performance...
Dynamics and stability control are the key factors to determine mode switch characteristics of multi-mode electro-mechanical transmission (EMT) which has been extensively applied in heavy-load vehicles as an innovative power-split transmission technology of hybrid electric vehicle. Based on cooperative work between the diesel engine with variable-speed governor and the generator with torque control,...
This brief paper describes the development of a pulse compression probing algorithm for real-time monitoring of nonlinear dynamic systems. The probing outputs of a system being monitored are estimates of the sequences of Markov parameters at the current operating point. By imposing signal to noise ratios at both the controlled outputs and the probing outputs, the probing inputs are designed to be...
