Abstract
The invention discloses a system and a method for controlling folding of vehicle rear-view mirrors. The method comprises the following steps: step 1, a distance between an external object and each rear-view mirror is detected in real time by virtue of a distance sensor, and each detected distance is conveyed to a rear-view mirror control module; and step 2, after receiving the distance data conveyed by the corresponding distance sensor, each rear-view mirror control module judges the value relationship between the distance data and a safety threshold value, and controls automatic folding and unfolding of the corresponding vehicle rear-view mirror according to a judgement result. According to the invention, the distance sensors are installed on the rear-view mirrors, when the detected distance between the external object and each rear-view mirror reaches the safety threshold value, the rear-view mirror is automatically folded, and after the external object is away from each rear-view mirror, the rear-view mirror is automatically unfolded; therefore, the occurrences of accidental injuries can be avoided.
Description
Technical field
The present invention relates to automotive field, particularly relate to a kind of vehicle mirrors folding control system and method.
Background technology
The back mirror of existing vehicle, generally all has manually or the function of electric foldable, to avoid vehicle to be arrived by scratching when parking or travel in narrower track, no matter and back mirror is manual or Electronic control all needs chaufeur initiatively to go to select.But, vehicle may have some beyond thought collisions in motion, in this type of collision, chaufeur has little time to make action to the folding of back mirror at all, thus cause back mirror to be collided, very easily produce again the fragment of splashing after back mirror is knocked, bring injury to chaufeur or periphery personnel.
Certainly, also having occurred some technology for unexpected auto-folder back mirror in prior art, is generally carry out Synchronization Analysis after utilizing pick up camera Real-time Collection external information, although this mode can reach corresponding object, but the computing power that this process need is stronger, practicality is poor.
Summary of the invention
For overcoming the deficiency that above-mentioned prior art exists, the object of the present invention is to provide a kind of vehicle mirrors folding control system and method, it is by mounting distance sensor on back mirror, when detect external object distance back mirror reach safe threshold time, auto-folder back mirror, when away from after, Automatic-expanding back mirror, avoids the generation of unexpected injury.
For reaching above-mentioned and other object, the present invention proposes a kind of vehicle mirrors folding control system, comprising:
Rang sensor, for detecting the distance of external object distance back mirror in real time, and is sent to rear-view mirror control module by the distance detected;
Rear-view mirror control module, after receiving the range data that this rang sensor transmits, judges the magnitude relationship of this range data and a secure threshold, and controls auto-folder and the expansion of vehicle mirrors according to judged result.
Further, this rang sensor is installed on this vehicle mirrors.
Further, when this rear-view mirror control module judges that the range data detected is greater than this secure threshold, judge whether Current vehicle back mirror is in deployed condition further, if be in deployed condition, then control it and carry out auto-folder, if current back mirror is in folded state, then do not carry out any operation.
Further, when this rear-view mirror control module judges that the range data detected is less than secure threshold, then judge whether Current vehicle back mirror is in folded state further, if current back mirror is in folded state, then control it and carry out Automatic-expanding, if current back mirror is in deployed condition, then do not carry out any operation.
Further, this secure threshold is user's setting or the setting of employing system default.
Further, this secure threshold is 5 ~ 20cm.
For achieving the above object, the present invention also provides a kind of vehicle mirrors to fold control method, comprises the steps:
Step one, utilizes rang sensor to detect the distance of external object apart from this back mirror in real time, and the distance detected is sent to rear-view mirror control module;
Step 2, this rear-view mirror control module, after receiving the range data that this rang sensor transmits, judges the magnitude relationship of this range data and a secure threshold, and controls auto-folder and the expansion of vehicle mirrors according to judged result.
Further, this rang sensor is arranged on this vehicle mirrors.
Further, in step 2, when this rear-view mirror control module judges that the range data detected is greater than this secure threshold, then judge whether Current vehicle back mirror is in deployed condition further, if be in deployed condition, then control it and carry out auto-folder, if current back mirror is in folded state, then do not carry out any operation.
Further, in step 2, when this rear-view mirror control module judges that the range data detected is less than secure threshold, then judge whether Current vehicle back mirror is in folded state further, if current back mirror is in folded state, then control it and carry out Automatic-expanding, if current back mirror is in deployed condition, then do not carry out any operation.
Compared with prior art, a kind of vehicle mirrors folding control system of the present invention and method, it is by mounting distance sensor on back mirror, when detect external object distance back mirror reach safe threshold time, auto-folder back mirror, when away from after, Automatic-expanding back mirror, avoids the generation of unexpected injury.

Detailed description of the invention
Below by way of specific instantiation and accompanying drawings embodiments of the present invention, those skilled in the art can understand other advantage of the present invention and effect easily by content disclosed in the present specification.The present invention is also implemented by other different instantiation or is applied, and the every details in this specification sheets also can based on different viewpoints and application, carries out various modification and change not deviating under spirit of the present invention.
Fig. 1 is the system architecture diagram of a kind of vehicle mirrors folding control system of the present invention.As shown in Figure 1, a kind of vehicle mirrors folding control system of the present invention, comprising: rang sensor 10 and rear-view mirror control module 11.
Wherein, rang sensor 10 is installed on vehicle mirrors, for detecting the distance of external object distance back mirror in real time, and the distance detected is sent to rear-view mirror control module 11; Rear-view mirror control module 11 is after receiving the range data that rang sensor 10 transmits, judge the magnitude relationship of this range data and a secure threshold, and auto-folder and the expansion of vehicle mirrors is controlled according to judged result, particularly, when rear-view mirror control module 11 judges that the range data detected is greater than this secure threshold, judge whether Current vehicle back mirror is in deployed condition further, if be in deployed condition, then control it and carry out auto-folder, if current back mirror is in folded state, then do not carry out any operation; When rear-view mirror control module 11 judges that the range data detected is less than secure threshold, then judge whether Current vehicle back mirror is in folded state further, if current back mirror is in folded state, then control it and carry out Automatic-expanding, if current back mirror is in deployed condition, then do not carry out any operation.In present pre-ferred embodiments, this secure threshold is 5 ~ 20cm, it manually can be set by user, namely user is provided manually to set by a user interface, also system default threshold value (such as this secure threshold of system default is 10cm) can be adopted, to this, the present invention does not do any restriction.
