Study on Hybrid Vehicle Regenerative Braking Control Parameters Affecting to Vehicle Performance Analysis and Simulation

In the hybrid vehicle applied basic research and engineering development, regenerative braking is to reduce energy consumption, reduce emissions and increase the driving range of the important means. According to the different hybrid vehicle driving conditions, how to use regenerative braking control parameters, thereby enhancing the braking energy recovery, is a hybrid car regenerative braking system of the heart. In this paper, the regenerative braking control parameters of the hybrid electric vehicle, by a reasonable choice of regenerative braking of the hybrid vehicle control parameters can increase the regenerative braking energy recovery, for reducing fuel consumption and maintain SOC are benefits. Computer Numerical simulation and simulation results show that the regenerative brake control parameters for hybrid vehicle fuel consumption and greater impact on the SOC, and the regenerative braking may affect the minimum speed limit of the regenerative braking effect, the lower the minimum speed limit the greater the braking energy recovery, thesis research is regenerative braking hybrid vehicle control parameters selected to provide a reference.

Research of CAN Bus Extension System Based on C8051F500 and SST39LF512

The transmission system is a core component of the hybrid vehicle. For the stability of vehicle power transmission, the Transmission Control Unit (TCU) must have communications with Vehicle Control Unit (VCU) and operation objects (such as drive motor, battery and so on) by CAN bus at the same time. In this paper, a CAN bus extension system based on C8051F500 and SST39LF512 was designed and completed the correct data sending and receiving, which met the communications requirements in hybrid vehicle control.

Study on the Engine Start/Stop Control Strategy of Hybrid Vehicles

The hybrid vehicle is currently one of the research focuses of automotive industry. The mode of ‘engine start/stop strategy’ has become a crucial part in (hybrid) vehicle control strategy. In this paper, both home and abroad researches of the ‘engine start/stop control strategy’ were summed up. From automotive engineering perspective, several aspects were in-depth analyzed and discussed, including the engine providing control energy or power resources, substitutability of energy and the negative problems brought by starting/stopping the engine. According to economy and overall loss, the objective function of optimization of the strategy was proposed. For solving the related engineering application problems caused by using the engine start/stop strategy on hybrid vehicles, the appropriate additional solutions were given from three aspects such as adding power source, controlling and switching clutch program of power source, and coupling and connection of the engine and auxiliary energy, providing an important reference for related study.
