For traditional gearbox, the engine power is cut off while shifting, which will interrupt the power of power-train, make velocity down, affect the acceleration of up gear and lower the vehicle dynamic. A double electric motor hybrid electric vehicle (HEV) that designed in a particular integrated power-train structure provides the necessary condition to deal with power interrupting while shifting....
Based on the first generation of hybrid electric city bus CA6110HEV developed by FAW (First Automobile Workshop) in China, the new generation of hybrid plug-in bus was designed, mainly including the parameters matching for the power-train and power sources. Then simulation platform were developed and established. The dynamic and economy performances were predicted based on the above work, results...
Co-simulation model of forward hybrid electric vehicle (HEV) is established in this paper. And according to three aspects: traditional vehicle model (mechanism system model), electric system model and vehicle control strategy, the precision of the co-simulation model has been analyzed and checked by the revolving drum test bench of the First Automobile Workshop (FAW). The forward simulation model...
The fundamental performance parameters of traction motor for electric vehicle directly influence the motor efficiency region, so the maxima driving range of vehicle is affected. According to empirical design formulae and orthogonal optimization theory of induction motor, this paper designs an orthogonal project with four factors. The simulation results of china city driving cycle that come from electric...
The properties of auxiliary brake and the influences of auxiliary brake to car performance are introduced. The engine brake characters and its influence factors are explained, and the engine brake performance experiment is expounded. It is discussed that the necessity of control CVT ratio during engine braking. The conception of setting vehicle velocity during engine brakes is proposed, the engine...
The mechanical property curve, efficiency and speed operation regions of induction traction motor for electric vehicle are introduced here. According to the vehicle's driving characteristic, the motor mechanical property curve is determined. Within the scope of mechanical property region of the motor, the method of regulating motor efficiency region is presented. Within the speed region, the relation...
In this paper, based on a battery pure electric city bus, principle researches have been offered on the parameters matching of the power-train and main components. The vehicle system was designed integrated, and then simulation platform was developed and established. The dynamic and economy performance can be predicted based on the above work, results show that the designed pure electric city bus...
In this paper, CAN Bus, which works in good real-time and high reliability, was designed and programmed based on 32-bit CPU-MPC5xx with high performance for hybrid electric vehicle (HEV). HEV controller based on MPC5xx was developed which can transfer data by CAN Bus with other ECUs of drivetrain assemblies such as engine, motor and battery according to the HEV control algorithm and requirements....
