Range extension control system of electric vehicle with advanced safety function

电动汽车作为零排放的交通工具，已经引起了人们的广泛关注。此外，由于电动机比内燃机更紧凑，电动汽车中使用的驱动系统可以以各种组合物实现。然而，目前还没有研究对不同类型的电动汽车驱动系统在相同条件下的性能进行比较。因此，为了比较各种电动汽车的驱动系统，我们开发了一款名为FPEV4-Sawyer的实验车。这辆车的驱动系统可以更换。从使用车载电机到基于轮内电机，反之亦然——通过使用可变单元系统。我们还为每个驱动系统开发了新颖先进的安全控制和范围扩展控制。

Electric vehicles (EVs) have attracted considerable interest as zero-emission vehicles. Moreover, because motors are more compact than internal-combustion engines, the drive system used in EVs may be implemented in a variety of compositions. However, there has been no research to compare the performances of different types of EV drive systems under identical conditions. Thus, to compare the various drive systems for EVs, we developed an experimental vehicle named FPEV4-Sawyer. The drive system of this vehicle can be changed---e.g., from one using an on-board motor to one based on in-wheel motors, and vice versa---by using a variable unit system. We also developed novel advanced safety control and range extension control for each drive system.
