Problems solved by technology

[0003] However, in the conventional motor drive system, when a restraint occurs during the opening / closing of the logo, it is impossible to know whether it is ① restraint due to icing or ② restraint due to foreign objects, and when the restraint is due to icing, because it is not released However, if unnecessary current is applied to the motor and excessive current flows, it is impossible to interrupt the motor drive accordingly.
Therefore, there is a problem that the motor drive cannot be interrupted at an appropriate time and damage to the motor occurs.

Abstract

The invention describes a motor protection device which comprises a sensing portion sensing the constraint of a motor, a temperature sensing portion measuring the external temperature of a motor, a control portion obtaining state information of the motor through the sensing portion and / or the temperature sensing portion, analyzing current flowing through the motor and outputting corresponding signals, and a hot line receiving the control signals from the control portion to provided heat energy to the motor and determining whether the constraint of the motor, when exists, is icing constraints or foreign matter constraints through the sensing portion and / or the temperature sensing portion. In this way, the determination of icing constraint is more objective, and the constrained can be solved by exciting the hot line when the motor constraint is determined to icing constraint. The motor protection device blocks overcurrent continuously flowing through the motor and stops the motor drive at a proper time to prevent damage of the motor, thereby facilitating safe driving.

Description

Technical field [0001] The invention relates to a motor protection method and device, and more particularly to an ARVS (Active Rear View System, Active Rear View System) motor protection method and device that assists the vehicle when it is parked in reverse. Background technique [0002] A rear camera will be installed on the rear logo of the vehicle. When the logo is opened / closed, the rear camera will run / stop correspondingly to provide the rear image of the vehicle, so as to show the driver when the vehicle is parked. provide help. In the past, the motor of the vehicle logo after operation, when the vehicle logo is turned on / off, it will turn on / off three times when it senses the constraint, and it will maintain the current vehicle logo state when it senses the constraint after three iterations. [0003] However, in the conventional motor drive system, when a restriction occurs during the opening / closing of the vehicle logo, it is impossible to know whether it is due to ① the ...
