Range extension control system of electric vehicle with advanced safety function

电动车辆（EV）作为零排放车辆已经吸引了相当大的兴趣。此外，因为电动机比内燃机更紧凑，所以EV中使用的驱动系统可以以各种组成来实现。然而，目前还没有研究比较不同类型的电动汽车驱动系统在相同的条件下的性能。因此，为了比较电动汽车的各种驱动系统，我们开发了一种名为FPEV 4-索耶的实验车辆。该车辆的驱动系统可以改变-例如，从使用车载电机到基于轮内电机，反之亦然--通过使用可变单位系统。我们还为每个驱动系统开发了新颖的先进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.
