Control apparatus and method for electric vehicles

In electric vehicle control, system voltage stabilization control is executed to reduce the difference (Vs) between a target value (Vs*) and detected value (Vsf) of a system voltage generated by a voltage boosting converter (21) for an AC motor (13, 14). Further, conversion power control is execute...

Beschreibung
Zusammenfassung:	In electric vehicle control, system voltage stabilization control is executed to reduce the difference (Vs) between a target value (Vs) and detected value (Vsf) of a system voltage generated by a voltage boosting converter (21) for an AC motor (13, 14). Further, conversion power control is executed to reduce the difference (Pi) between a command value (Pif) and detected value (Pi) of the conversion power, which is defined as the output power of the voltage boosting converter (21). Thus, variations in a system voltage caused by an error or the conversion power control can be reduced.
