Abstract
Official abstract text for this publication.
In the case where an on-fixation failure occurs in one of transistors of an inverter, a shutdown signal GSDWN or MSDWN is output as ON signal for a duration of adjusting time since switching of a fail signal GFINV or MFINV to ON signal. After elapse of the adjustment time, the shutdown signal GSDWN or MSDWN is switched to OFF signal. The adjustment time is set to be longer than a time duration until completion of shutdown of the inverter but to be shorter than a time duration until start of emergency drive control. This allows for cancellation of shutdown of the inverter even when an abnormal signal is continuously output due to a failure of a sensor or the like. This causes emergency drive to be more reliably performed with three-phase on-control including a transistor having an on-fixation failure after shutdown of the inverter.
First claim
Opening claim text (preview).
1 . A motor vehicle, comprising a power source that is configured to output power to an axle; a motor that is mechanically linked with the axle; an inverter that is configured to have a plurality of switching elements and drive the motor; an abnormal signal generator that is configured to switch an abnormal signal on in the case where a fault occurs in any of the plurality of switching elements; a shutdown controller that is configured to shut down the inverter when a shutdown abnormal…
