Abstract: A vehicle includes a motor, a driving device, and a cooling device. The motor includes a motor main body and a winding switching unit. The motor main body includes windings and a first coolant channel to cool said windings. The winding switching unit is disposed on an outer surface of said motor main body and includes heat-generating components and a second coolant channel. The heat-generating components are used to switch said windings. The second coolant channel is to cool said heat-generating components. The driving device is configured to control switching of said winding switching unit and configured to apply driving voltage to said windings, the drive device including a third coolant channel. The cooling device is to cool coolant that flows through said first coolant channel, said second coolant channel and said third coolant channel.
