a device for thermal monitoring of an electric motor on board a vehicle, in particular for a servolenkungssystem

摘要

The present invention relates to a method and a device for thermal monitoring of an electric motor on board a vehicle, the electric motor being a part of a vehicle electromechanical actuator. It finds application in particular for a power-steering system. The invention makes it possible to carry out a phase of surveillance of the cooling of the unpowered electric motor which produces a restart temperature value. This value is exploited during a phase of thermal monitoring of the powered electric motor which prohibits the exceeding of an acceptable maximum temperature. Application to on-board actuators such as power steering. IMAGE
