Title:
MOTOR RELATED COMPONENT OVERHEAT PREVENTION METHOD AND OVERHEAT PREVENTION SYSTEM
Document Type and Number:
Japanese Patent JP2021097542
Kind Code:
A
Abstract:
To enable overheat prevention processing to be appropriately performed in accordance with a risk that a motor related component is overheated without requiring cumbersome operation such as destination setting.SOLUTION: A server recording medium 70 stores overheat risk area information in which an overheat risk area is determined on the basis of motor temperatures TM at many points Px, travel locations PV, that an electric vehicle 12 passes. An on-vehicle electronic control device 20: determines whether or not an electric vehicle 12 travels the overheat risk area on the basis of the overheat risk area information; and executes motor cooling processing to prevent an electric motor 42 from being overheated when determining that the electric vehicle travels the overheat risk area. Thus, the motor cooling processing can be executed on the basis of a risk that the electric motor 42 is overheated without requiring cumbersome operation such as destination setting and thereby enabling the electric motor 42 to be appropriately protected from being overheated.SELECTED DRAWING: Figure 1
