Electric mirror control device

Abstract

An electric mirror control device is provided which can prevent generation of a clutch noise by stopping slipping of a clutch provided at an actuator as quickly as possible while preventing narrowing of an allowable range of a tilting angle of a mirror surface. In controlling an electric mirror, a control device clamps a voltage value of a voltage applied to a motor detected by a mirror surface angle detection circuit to a predetermined upper limit value and a predetermined lower limit value at a clamp circuit. Stop control of the motor is performed based on the voltage value clamped to the upper limit value and the lower limit value in this way.

1 . An electric mirror control device, including a control method for an automobile electric mirror in which drive control of the electric mirror is performed by controlling an actuator for operating the electric mirror mounted on an automobile, comprising: 
 a voltage sensor for detecting a voltage value applied to the actuator when the actuator is in operation;    a clamp means for clamping the voltage value detected by the voltage sensor to a predetermined limit value; and    a stop control means for performing stop control of the actuator based on the voltage value detected by the voltage sensor and outputted through the clamp means.    
   
   
       2 . The electric mirror control device according to  claim 1 , wherein at least one of a predetermined upper limit value and a predetermined lower limit value is set as the limit value, and wherein 
 the stop control means stops the actuator when the voltage value detected by the voltage sensor exceeds the predetermined upper limit value or drops below the predetermined lower limit value.    
   
   
       3 . The electric mirror control device according to  claim 1 , wherein the electric mirror has a case to which a mirror main body is mounted, a mirror surface angle of the mirror main body being adjustable with respect to the case, and 
 the actuator drives the mirror main body so that the mirror surface angle of the mirror main body is adjusted.
