WIPO Patent Application WO/2017/112402
Kind Code:
A8
Abstract:
Systems and methods are disclosed for improving acceleration performance of an electric vehicle that includes an electric motor for propulsion. An exemplary system may include an inverter configured to drive the electric motor. The inverter may include at least one power electronic device. The system may also include a torque capability controller. The torque capability controller may he configured to receive information indicative of a selection between a first mode and a second mode. The second mode may correspond to a higher torque to be output by the electric motor than the first mode. The torque capability controller may also be configured to apply a switching frequency to the at least, one power electronic device.
