Based on observations of the behaviour optimal solution to problem energy management for plug-in hybrid electric vehicles, a novel real-time Energy Management Strategy (EMS) is proposed. In particular, dynamic programming results are used derive set rules aiming at reproducing gearshift schedule in mode while Adaptive Equivalent Consumption Minimization (A-ECMS) employed decide powertrain operating and current gear when power from internal combustion engine needed. terms total fuel...
This paper presents a methodology for the assessment of NVH (noise vibration and harshness) performance Dual Clutch Transmissions (DCTs) depending on some transmission design parameters, e.g. torsional backlash in synchronizers or clutch disc moment inertia, during low speed maneuvers. A 21-DOFs nonlinear dynamic model C-segment passenger car equipped with DCT is used to simulate behavior driveline estimate forces at bearings. The impacts between teeth two engaging components, gears...
This article describes gearshift control strategies developed for a series-parallel hybrid electric vehicle architecture in which an machine is connected to the output of transmission, thus obtaining torque filling capabilities during gearshifts. Two transmission systems are analyzed: automated manual and dual-clutch transmission. The focuses on two splitting each into several phases. objectives phase, equations computing set points powertrain actuators, conditions that determine passage...
The introduction of hybrid vehicle architectures into the mass car market has dramatically increased fault detection and mitigation strategies seen in vehicles to match growth potential failures coming from increasingly complex powertrain architectures. To meet this demand for multiple components, advanced methodologies have been developed determine functional safety systems. This paper focuses on use one those methodologies, structural analysis, develop design, implementation, diagnostics,...
Order tracking is a method of analysis used by engineers in the diagnosis rotating machinery. In many applications, order non-stationary signals required. The direct extraction amplitude information from short-time Fourier transform may lead to inaccurate vibration-level estimation case fast changes signal frequency content. This article discusses spectral smearing, which main reason problem, and its sensitivity characteristics (frequency variations) input parameters discrete (window size...
This paper describes a control algorithm for gearshifts maneuvers designed hybrid electric vehicle architecture in which an machine is connected to the output of traditional five-speed automated manual transmission, thus obtaining torque-fill capability during gearshifts. The controller realized dividing entire gearshift process into five phases. objectives each phase, equations computing signals and conditions that determine passage from one phase next are reported. A nonlinear dynamic...
