In order to make the object, technical scheme and advantages of the embodiment of the invention clearer, below in conjunction with the embodiment of the present invention
In attached drawing, technical scheme in the embodiment of the invention is clearly and completely described, it is clear that described embodiment is
A part of the embodiment of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art
The every other embodiment obtained without making creative work, shall fall within the protection scope of the present invention.
Referring to FIG. 1, Fig. 1 is a kind of flow signal of temperature protecting method of automotive rear-view mirror motor provided by the invention
Figure, including：
Step S1：Enter sleep state in motor stopping；
Subsequent timing difference can be enable accurately to embody specifically, entering sleep state in motor stopping
The cooling time of motor has reached timing difference, ensures the temperature fall time of motor, ensure that safety.
Step S2：Obtain the first clocking value when the controller enters sleep；
Specifically, it can be user's active control that controller, which enters sleep, can also be journey of the controller according to itself
Sequence does not limit herein automatically into sleep, the embodiment of the present invention.
Step S3：Obtain the second clocking value when the controller is waken up wake instruction and by second clocking value with
First clocking value makes the difference to obtain timing difference；
Specifically, the first clocking value can enter what that time slept read immediately by device in order to control, the second clocking value
It device can read in order to control in that time for being just waken up, the timing difference judged in such cases is more accurate, has
Conducive to accurately calculate motor cooling time.
Step S4：Judge whether timing difference is more than motor threshold value cooling time；
Wherein, motor threshold value cooling time, which is the own temperature of motor, can be reduced to the time threshold of safe working temperature
Value, can be measured by multiple experiment, such as is measured to play when multiple motor shuts down certainly and be reduced to safe working temperature institute
The time needed, and handled to obtain motor threshold value cooling time to measuring obtained multigroup time, the embodiment of the present invention exists
This is not limited.
Step S5：If so, allowing driving motor.
In view of the technical problem in above-mentioned background technology, in the embodiment of the present invention, controller can enter sleep when
The first current clocking value is preserved, the second clocking value is read when being waken up wake instruction and is made the difference with the first clocking value and is counted
Time difference value allows to start motor, in such cases, controller can be with if the timing difference is more than motor threshold value cooling time
It is in sleep state for a long time, controller can only be by external wake-up wake instruction, and judges whether timing difference reaches electricity
Machine threshold value cooling time just can guarantee that the temperature of motor is reduced to the numerical value suitable for booting, allows electricity in the case where reaching
The drive actions of machine reduce the use of electric energy, have saved electricity without running controller for a long time in the embodiment of the present invention
Can, extend the service life of controller.
Wherein, the action of driving motor is allowed generate one of device itself can to allow motor-driven mark in order to control,
After having this to indicate, when controller receives the order for opening motor, controller will be sent to rearview mirror motor driver
Actuating signal by it to drive backsight mirror motor to complete breakdown action.
It can be sent out by bus or rigid line by other controllers of vehicle in addition, external control instruction either wakes up instruction
Give rearview mirror controller.
The present invention provides a kind of temperature protecting methods of automotive rear-view mirror motor, are applied to controller, are included in motor
Enter sleep state when shutdown；Obtain the first clocking value when controller enters sleep；It obtains controller and is waken up wake instruction
When the second clocking value and make the difference the second clocking value and the first clocking value to obtain timing difference；Judge whether timing difference is more than
Motor threshold value cooling time；If so, allowing driving motor.
As it can be seen that in the present invention, controller can enter sleep state in motor stopping, can be immediately when entering and sleeping
The first current clocking value is preserved, the second clocking value is read again when being waken up and makes the difference itself and the first clocking value to obtain timing
Difference allows driving motor, the controller in the present invention that can be constantly in if timing difference is more than motor threshold value cooling time
Sleep state, when outside has wake-up instruction to wake up controller, controller can judge whether motor reaches by timing result
Enough cooling times, in the case where ensure that motor is operated in safe temperature so that controller is for a long time in sleep shape
State reduces the loss of electric energy, extends the service life of controller.
On the basis of the above embodiments：
Embodiment as one preferred, before entering sleep state in motor stopping, which also wraps
It includes：
Judge whether motor shuts down.
Specifically, in order to ensure controller is at the time of it is that motor is just begun to cool to enter timing numerical value when sleeping, this
It can judge whether to meet sleep condition before controller enters sleep in inventive embodiments, only meet motor stopping
Sleep state can just be entered when condition, reduce the probability of malfunction, improve work efficiency.
Wherein, the first clocking value preserved at this time may insure it is clocking value that motor is in cooling time, will not occur
The case where motor shuts down just the first clocking value of record not yet, further assure that motor can cool down time enough,
Improve safety.
Wherein, motor stopping can be specially that time that motor has just been shut down, and controller just initially enters sleep, such feelings
Electric energy has further been saved under condition, extends the service life of controller.
Embodiment as one preferred, judges whether timing difference is more than after motor threshold value cooling time, the temperature
Guard method further includes：
If it is not, then entering sleep state.
Specifically, in the embodiment of the present invention, when controller judges that timing difference is less than or equal to motor threshold cooling time
When value, sleep state can be entered, the duration that controller is waken up can be reduced in such cases, further save electricity
Can, extend the service life of controller.
Wherein, if it is not, then enter sleep state can in order to control device itself program control, or outside user
Control enters sleep, and the embodiment of the present invention does not limit herein.
In addition, other than entering and sleeping, if actual difference is not more than motor threshold value cooling time, it can also generate and forbid electricity
Machine driving mark, in such cases, even if having received the instruction of external driving motor, controller will not send out action letter
Number with driving motor, motor safety is further assured that.
Embodiment as one preferred, the first clocking value and the second clocking value are the counter note inside controller
The numerical value of record.
Specifically, the first clocking value and the second clocking value are the numerical value of the counter records inside controller, utilize
It can not have to that a time set is individually arranged again when counter counts inside controller, the counter inside controller can be
Keeping count after controller sleep, the technical solution in the embodiment of the present invention can be realized using the counter of controller itself,
Save cost.
Certainly, other than the counter inside controller, the first clocking value and the second clocking value can also utilize additionally
The time set of setting realizes that the embodiment of the present invention does not limit herein.
