Y-delta all-wheel electric drive system for electrically powered vehicle

The present disclosure provides a Y-delta all-wheel electric drive system for an electrically powered vehicle. The vehicle includes a first electric machine and a second electric machine driven by aninverter and coupled to a first set of wheels and a second set of wheels. The vehicle includes a switch configured to selectively connect each of the electric machines in one of a Y-connection mannerand a delta connection manner. The vehicle also includes a controller programmed to operate the switch to select a connection manner for the electric machines based on a speed of the vehicle and operate the inverter to share a torque demand between the electric machines. 本公开提供了"用于电动化车辆的Y形-三角形全轮电驱动系统"。一种车辆，包括第一电机和第二电机，所述第一电机和第二电机由逆变器驱动并且联接到第一组车轮和第二组车轮。所述车辆包括开关，所述开关被配置为选择性地以Y形连接方式和三角形连接方式中的一者连接所述电机中的每一者。所述车辆还包括控制器，所述控制器被编程为基于所述车辆的速度来操作所述开关以选择用于所述电机的连接方式并且操作所述逆变器以将扭矩需求分摊在所述电机之间。
