Range extension control system of electric vehicle with advanced safety function

电动汽车作为零排放汽车已经引起了人们的极大兴趣。此外，由于发动机比内燃机更紧凑，电动汽车中使用的驱动系统可能会以各种组合来实现。然而，还没有研究比较不同类型的电动汽车驱动系统在相同条件下的性能。因此，为了比较电动汽车的各种驱动系统，我们开发了一辆名为FPEV4-Sawyer的实验车。这种车辆的驱动系统可以通过使用可变单位系统来改变-例如，从使用车载马达的驱动系统改为基于车轮马达的驱动系统，反之亦然。我们还为每个驱动系统开发了新颖的高级安全控制和续航里程扩展控制。

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.
