In addition, the control unit of the vehicle side rear-rear distance sensing apparatus according to the present invention, when an object is detected within a predetermined distance from any one of the front and rear side sensor, the side is equipped with the corresponding sensor is detected The mirror is controlled to be folded once automatically.

In addition, the control unit of the vehicle rear-rear distance sensing apparatus according to the present invention, if the object is not detected within a predetermined distance from any one of the front and rear sensor, the side mirror so as to unfold the folded side mirror automatically. It is characterized by controlling.

In addition, the control unit of the vehicle side rear-side distance detecting apparatus according to the present invention, it is preferable to control the warning unit so that the speed of the warning sound is also faster as the receiving interval of the detection signal received from the sensors.

As described above, the present invention can protect the back and the side of the vehicle and at the same time promote the safety of the driver, and protect the property and life by protecting the facilities in the common parking lot and other vehicles and people passing through the rear and side of the vehicle. There is an effect that can protect.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a detailed description of preferred embodiments of the present invention will be given with reference to the accompanying drawings. It should be noted that the same components in the figures represent the same numerals wherever possible. Specific details are set forth in the following description, which is provided to provide a more thorough understanding of the present invention. In the following description of the present invention, detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear.

The vehicle side rear distance detection apparatus according to the present invention is to attach the side sensor to the vehicle to protect the side and side mirrors without a large cost.

1 is a view showing the position of the sensor installed on the outside of the vehicle according to the present invention, Figure 2 is a view showing the position of the sensor installed on the rear of the side mirror, that is, the mirror surface of the vehicle according to the invention, Figure 3 Is a view showing the position of the sensor installed on the front side mirror of the vehicle according to the present invention.

1 to 3, the present invention provides a sensor (e.g., ultrasonic sensor) in front of and behind the vehicle rear bumper and both side mirrors when the vehicle is parked or moved from one parking area to another. ), It transmits and receives each ultrasonic sensor alternately and measures the presence and distance of obstacles and informs the driver with buzzer sound and various display devices.

As illustrated in FIG. 1, the vehicle rear bumper is equipped with a plurality of rear detection sensors, and one side mirror front and rear sensors are mounted at the front and the rear of both side mirrors, respectively.

As shown in FIG. 2, the side mirror rear sensor is provided at one side of the side mirror mirror surface of the vehicle, and as shown in FIG. 3, the side mirror front sensor is provided at the rear side of the side mirror mirror surface of the vehicle.

Referring to the operation of the vehicle rear-rear distance sensing device according to the present invention with reference to Figures 1 to 3, when the data of the reverse gear is input, the sensors on the rear bumper and the sensor on the rear of the side mirror (mirror surface) When the gear is first input or less than 10 km / h, the sensor on the front of the side mirror is activated to measure the distance between the front and rear objects of the side mirror.

Sensors used in the vehicle side rear-side distance detection device according to the present invention, in the case of the rear sensor is preferably able to detect the distance of the object detected from the rear 10cm or more and less than 2M, the sensor of the sensor mounted on the side mirror In this case, it is preferable that the distance from the detected object is designed to detect a distance of 10 cm or more and 1.5 M or less.

In addition, the front side mirror front sensor mounted on the front of the side mirror to operate the vehicle when the first gear or the vehicle speed is less than 10km per hour, and the measurement distance within 1.5M so as not to exceed 50cm from the front bumper It is preferable not to perform unnecessary operation due to the distance to the front vehicle at the time of departure.

On the other hand, if an object is detected within 30cm of the front side mirror's front sensor, the side mirror equipped with the corresponding sensor on which the object is detected is automatically folded one time under the control of the controller and at the same time, to prevent damage to the side mirror. You can also prevent it automatically. In addition, it is preferable to automatically unfold the side mirror when the side mirror front sensor operates automatically when no object is detected within 30 cm.

On the other hand, the warning sound may be faster as the warning interval of the detection signal received from each sensor is faster.

The formula for calculating the distance between the obstacle and the sensor is shown in Equation 1 below.

d = (v * t) / 2

Here, d is the distance between the obstacle and the sensor, v is the ultrasonic speed at room temperature, t is the ultrasonic transmission and reception time.

The distance (d) between the sensor and the obstacle is divided by 2 by multiplying the distance to the object by the speed of ultrasonic waves reciprocating the distance to the object by the time when the ultrasonic wave transmitted from the ultrasonic sensor is reflected by the object and received again by the ultrasonic sensor. The distance from the sensor to the obstacle can be obtained.
