Abstract

The utility model discloses an electronic outside rear-view mirror of car, including MPU-6050 digital gyroscope, angle sensor and Arduino controller, MPU-6050 digital gyroscope installs in the junction of automobile body with the rear-view mirror, and the Arduino controller sets up in control panel department, and angle sensor installs in one side of rear-view mirror, and MPU-6050 digital gyroscope, angle sensor and Arduino controller all connect through the wire. This automobile electric outside rear-view mirror, whether judged through Arduino controller and opened the button that improves the control strategy, if do not press and just take former car control strategy, if press just make Arduino controller read automobile body rotation angle variation and rear-view mirror's position respectively through MPU-6050 digital gyroscope and rear-view mirror angle sensor and control again, just so reduced the probability that the blind area accident takes place betterly.

Description

Electric outer rear-view mirror of automobile

Technical Field

The utility model relates to an automobile parts technical field specifically is an electronic outside rear-view mirror of car.

Background

With the rapid development of automobile industry in China, private cars have become important transportation tools for people to go out. With the increase of the number of automobiles, especially in some front-line big cities, under the condition that pedestrians, non-motor vehicles and motor vehicles are numerous on roads, traffic is increasingly serious except for the problem of congestion, and many irrecoverable tragedies occur in the blind area of the rearview mirror outside a driver. At present, the rearview mirrors of the household cars are mainly controlled electrically, except that the rearview mirrors on the right side of reversing are turned down and folded electrically, most of the set positions are fixed, and the visual angle cannot be adjusted automatically under special conditions, so that blind areas are easily generated between the automobiles and other motor lanes and non-motor lanes during merging and parking, and the automobiles are scratched and casualties are caused.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an electronic outside rear-view mirror of car to solve the problem that proposes among the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: the utility model provides an electronic outside rear-view mirror of car, includes MPU-6050 digital gyroscope, angle sensor and Arduino controller, the junction at automobile body and rear-view mirror is installed to MPU-6050 digital gyroscope, the Arduino controller sets up in control panel department, angle sensor installs the one side at the rear-view mirror, MPU-6050 digital gyroscope, angle sensor and Arduino controller all connect through the wire.

Preferably, the Arduino controller comprises a human body infrared sensing module, a smoke and combustible gas detection module and a temperature and humidity detection module DHT-11.

Preferably, the human body infrared sensing module is arranged on two sides of the vehicle body.

Preferably, the smoke and combustible gas detection module and the temperature and humidity detection module DHT-11 are arranged inside the vehicle body.

Preferably, the MPU-6050 digital gyroscope comprises a combination gyroscope and an accelerator.

Advantageous effects

The utility model provides an electronic outside rear-view mirror of car, this electronic outside rear-view mirror of car, through setting up MPU-6050 digital gyroscope, angle sensor and Arduino controller, make Arduino controller judge whether opened the button that improves the control strategy, if not press and just take former car control strategy, if press and just make Arduino controller pass through MPU-6050 digital gyroscope and rear-view mirror angle sensor and read the position of automobile body rotation angle variation and rear-view mirror respectively, carry out closed-loop control to the rear-view mirror again, it is the same with the automobile body corner to require rear-view mirror rotation angle, just so reduced the probability of blind area occurence of failure betterly.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Referring to fig. 1, the present invention provides a technical solution: the utility model provides an electronic outside rear-view mirror of car, includes MPU-6050 digital gyroscope, angle sensor and Arduino controller, MPU-6050 digital gyroscope installs in the junction of automobile body and rear-view mirror, Arduino controller sets up in control panel department, Arduino controller includes human infrared ray induction module, smog and combustible gas detection module and humiture detection module DHT-11, human infrared ray induction module sets up the both sides at the automobile body, smog and combustible gas detection module and humiture detection module DHT-11 set up inside the automobile body, angle sensor installs one side at the rear-view mirror, MPU-6050 digital gyroscope, angle sensor and Arduino controller all connect through the wire, MPU-6050 digital gyroscope includes combination gyroscope and accelerator, through setting up MPU-6050 digital gyroscope, The angle sensor and the Arduino controller enable the Arduino controller to judge whether a key for improving a control strategy is started or not, if the key is not pressed, an original vehicle control strategy is adopted, if the key is pressed, the Arduino controller respectively reads the vehicle body rotation angle variable quantity and the position of a rearview mirror through an MPU-6050 digital gyroscope and a rearview mirror angle sensor, then closed-loop control is carried out on the rearview mirror, the rotation angle of the rearview mirror is required to be the same as the vehicle body rotation angle, and therefore the probability of blind area accidents is well reduced.

The working principle is as follows: when the electric external rearview mirror is used, whether a key for improving a control strategy is started or not is judged by using the Arduino controller, if the key is not pressed, the original vehicle control strategy is adopted, if the key is pressed, the Arduino controller respectively reads the vehicle body rotation angle variable quantity and the position of the rearview mirror through the MPU-6050 digital gyroscope and the rearview mirror angle sensor, then the rearview mirror is subjected to closed-loop control, the rotation angle of the rearview mirror is required to be the same as the vehicle body rotation angle, and therefore the probability of blind area accidents is well reduced.

Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
