Abstract:
A hybrid type vehicle drive control apparatus, comprising:an electric generator that generates electric power by driving an engine; an electric generator inverter that drives the electric generator; a drive motor that drives a hybrid type vehicle; a drive motor inverter that drives the drive motor; a battery connected to the electric generator inverter and the drive motor inverter; a first voltage detection device that detects a voltage applied to the electric generator inverter; a second voltage detection device that detects a voltage applied to the drive motor inverter; a third voltage detection device that detects a battery voltage; and a system voltage determination processing device that determines a system voltage based on detection results provided by normal voltages of the first to third voltage detection devices if a detection abnormality occurs in any one of the first to third voltage detection devices.
