Fundamental limitations to no-jerk gearshifts of multi-speed transmission architectures in electric vehicles
نویسندگان
چکیده
Multi-speed transmissions can enhance the performance and reduce overall cost of an electric vehicle, but they also introduce a challenge: avoiding gearshift jerk, which may sometimes prove to be impossible in presence motor clutch saturation. In this article, we three theorems that explicitly define fundamental limitations no-jerk gearshifts resulting from or actuator We compare consist transferring transmission torque one friction another, case clutches is one-way clutch. show systems with are more prone saturation, causing jerk often inevitable. study influence planetary gearsets on dynamical trajectories, expose impact limitations. This work offers tools architectures during conceptual design phase new vehicle.

Significant Characteristics of Multi Carrier Energy Networks for Integration of Plug-In Electric Vehicles to Electric Distribution Network
One of the big concerns of big cities is facing with the increase of fossil fuel vehicles in the roads. The cars intensify greenhouse gas emission in civic centers. One approach to reduce the emission is replacing the cars by Plug-In Electric Vehicles (PEVs). In spite of reducing the emission, PEVs have some adverse effect on electric distribution networks. Technical challenges such as load and...
