Abstract
On a vehicle, a converter converting and outputting a voltage, an inverter converting DC power output from the converter to AC power, and a motor driven by AC power supplied from the inverter are mounted. A control device for this vehicle controls the inverter in a control mode selected in accordance with a degree of modulation of the inverter, selects a target control mode of the inverter, and varies an output voltage from the converter such that a degree of modulation of the inverter varies until the control mode switches to the target control mode when a current control mode is different from the target control mode.
Claims12
A vehicle comprising:
- a converter converting and outputting a voltage;
- an inverter converting DC power output from said converter to AC power;
- a motor driven by AC power supplied from said inverter;
- and
- a control device configured to control said converter and said inverter,
- said control device
- controlling said inverter in a control mode selected in accordance with a degree of modulation of said inverter and selecting a target control mode of said inverter, and
- varying an output voltage from said converter such that a degree of modulation of said inverter varies until said control mode switches to said target control mode when a current control mode according to said degree of modulation is different from said target control mode.
A control device for a vehicle incorporating a converter converting and outputting a voltage, an inverter converting DC power output from said converter to AC power, and a motor driven by AC power supplied from said inverter, comprising:
- inverter control means for controlling said inverter in a control mode selected in accordance with a degree of modulation of said inverter;
- selection means for selecting a target control mode of said inverter;
- and
- converter control means for varying an output voltage from said converter such that a degree of modulation of said inverter varies until said control mode switches to said target control mode when a current control mode according to said degree of modulation is different from said target control mode.
