Title:
MOBILE BODY CONTROL DEVICE AND PROGRAM
Document Type and Number:
Japanese Patent JP2023003821
Kind Code:
A
Abstract:
To provide a mobile body control device and a program, which can inhibit an inverter and a rotary electric machine from becoming an overheat state.SOLUTION: In an operation region of operation points determined by the torque and rotation speed of a rotary electric machine 20, a first region and a second region adjacent to the first region are set, in which the second region includes a high-speed region on a high-speed side with respect to the first region. A MGCU36, when determining that a current operation point is within the high-speed region, predicts whether or not at least one of the rotary electric machine 20 and an inverter 30 falls into an overheat state when continuing torque control of the rotary electric machine 20, and when predicting that one of them falls into the overheat state, transmits information denoting that at least one of them falls into the overheat state to an EVCU 55. The EVCU 55, when receiving the information denoting that at least one of them falls into the overheat state, performs protection processing for inhibiting the rotary electric machine 20 and the inverter 30 from falling into the overheat state.SELECTED DRAWING: Figure 1
