Abstract

A vehicular outside-mirror control method may improve durability of a motor by appropriately controlling the motor according to a condition of peripheral temperature so as to prevent the motor implementing a folding function of the outside mirror from being damaged and improve assembling workability and save costs of a vehicle by reducing the number of wires connected with the door while performing various functions to be implemented by the outside mirror.

Claims

1. A control method for an outside mirror of a vehicle, the method comprising:

forming a data map for stall current of a motor in a predetermined temperature range;

measuring a present temperature;

obtaining a stall current according to the present temperature from the data map; and

stopping the motor when the stall current is sensed when a folding of the outside mirror is operated.

2. The method of claim 1, wherein the measuring of the present temperature is performed and the motor is activated for a predetermined reference operating time, when a folding start signal of the outside mirror is input, and

the stopping the motor is performed when current applied to the motor reaches the stall current before the reference operating time lapses.

3. The method of claim 1, wherein the forming the data map obtains and stores the stall current of the motor for each predetermined operating voltage applied to the motor in each temperature range, and

the obtaining of the stall current obtains the stall current according to the present temperature and the operating voltage provided by the present battery.

4. An outside mirror control method of a vehicle, comprising:

measuring a present temperature;

obtaining a stall current according to the present temperature from a data map for the stall current of the motor in a predetermined temperature range; and

stopping a driving of the motor when the stall current is sensed at the time of the folding operation of the outside mirror.

5. The method of claim 4, wherein the measuring of the temperature is performed and the motor is driven for a predetermined reference operating time when a folding start signal of the outside mirror is input, and

the stopping of the motor is performed when current applied to the motor reaches the stall current before the reference operating time lapses.

6. The method of claim 5, wherein the data map for the stall current of the motor in the predetermined temperature range is configured to include data of the stall current according to the operating voltage provided by the battery for each temperature range, and

the obtaining of the stall current obtains the stall current according to the present temperature and the operating voltage provided by the present battery.

7. An outside mirror control apparatus of a vehicle, comprising:

a storage device storing a data map of a stall current according to a predetermined temperature range;

a temperature sensor measuring a present temperature; and

a controller stopping a motor when operating current of the motor reaches the stall current at the time of a folding operation of the outside mirror by obtaining the stall current corresponding to the present temperature measured from the temperature sensor from the data map of the storage device.

8. The apparatus of claim 7, wherein the data map of the storage device 1 includes the data of the stall current according to the operating voltage provided by the battery for each temperature range, and

the controller is configured to stop the driving of the motor when the operating current of the motor reaches the stall current by obtaining the stall current according to the present temperature and the operating voltage provided by the present battery.

9. The apparatus of claim 8, further comprising an LIN module provided so as to perform local interconnect network (LIN) communication with another control module.
