Title:
MOTOR CONTROL DEVICE AND VEHICLE BRAKING DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/057875
Kind Code:
A1
Abstract:
Motor control devices (351-354) each comprise: a torque command calculation unit (40) that calculates a torque command value (Trq*); a current command calculation unit (50) that calculates a current command value (I*); a power converter (55); and a stop position adjuster (67). The stop position adjuster (67) executes a "stop position adjustment process" for adjusting the rotation stop position within a predetermined position adjustment range, during the locked energization which is energization performed when the polyphase motor (60) has stopped rotating, unless certain exemption requirements are met. In the stop position adjustment process, the stop position adjuster (67) adjusts the rotation stop position so as to bias the current to one or more high heat dissipation phases that have relatively high heat dissipation among phases. The torque command calculation unit (40) or the current command calculation unit (50) calculates the torque command value (Trq*) or the current command value (I*) that reflects the adjusted rotation stop position.
