Embodiment Construction

[0047] Embodiments of the present invention will be described in detail with reference to the drawings. The same or corresponding parts will be denoted by the same reference symbols, and description thereof will not be repeated.

[0048] 1, an electrical load device 100 according to an embodiment of the present invention includes a DC power supply B, a fuse FU, voltage sensors 10 and 20, system relays SR1 and SR2, capacitors 11 and 13, a DC / DC converter 12, an inverter 14 and 31, current sensors 24 and 28, control device 30, and AC motors M1 and M2.

[0049] AC motor M1 is mounted on, for example, a hybrid vehicle. The AC motor M1 is a drive motor for generating torque to drive drive wheels of the hybrid vehicle. Further, when the alternator M1 is rotated by the rotation of the drive wheels during deceleration of the vehicle or otherwise, the alternator M1 functions as a generator (so-called regenerative function).

[0050] AC motor M2 is mounted on, for example, a hybrid veh...

Abstract

Control apparatus (30) forcefully stops inverter (14) and inverter (31) when DC / DC converter (12) is anomalously stopped. Additionally, when one of inverters (14, 31) is anomalously stopped while DC / DC converter (12) is normal, control apparatus (30) forcefully stops the other inverter. Then, when a recovery condition is satisfied after the other inverter is forcefully stopped, control apparatus (30) recovers the other inverter.

Description

technical field [0001] The present invention relates to an electrical load device that handles a detected abnormality, a method of processing an abnormality in the electrical load device, and a computer-readable recording medium recording a program for causing a computer to execute abnormality processing in the electrical load device. Background technique [0002] Recently, hybrid vehicles have received much attention as environmentally friendly vehicles. Hybrid vehicles have been partially put into practical application. [0003] A hybrid vehicle is powered by a DC (direct current) power source, an inverter, and an electric motor driven by the inverter, in addition to a conventional engine. Specifically, while the vehicle is powered by driving the engine, the inverter also converts the DC voltage from the DC power supply into AC (alternating current) voltage and rotates the motor with the converted AC voltage to provide power to the vehicle. power. [0004] In such hybri...
