Description

Distance control system {control system of distance between cars}

1 is a block diagram showing a control system of the present invention.

The present invention relates to a distance control system.

More specifically, the vehicle can stably maintain or control the distance between the vehicle in front of the vehicle while driving, while also allowing the driver to recognize the situation more quickly in the event of a sudden situation, as well as controlling the vehicle such that the brake is momentarily activated. When you try to open the door when getting off, the rear detection is made smoothly to prevent collisions with bicycles, motorcycles, vehicles, etc. running from the rear in advance to maximize the safety.

As is well known, most of the causes of various traffic accidents, including vehicle contact accidents and collisions, are often caused by inadequate safety distances, inadvertent drivers, or accidents that the driver cannot help. .

In particular, in the case of highways, monotonous and boring driving is performed, and there is a high possibility of drowsy driving, and monotonous and boring during driving, so the distance between the vehicle in front of the vehicle is not recognized, and the sense is greatly reduced or bad weather including heavy fog or rainy weather. If you have no choice but to travel in a state that has not been confirmed, such as a city, the vehicle has already crashed or crashed at the moment when you feel it is dangerous, resulting in damage to the vehicle or other objects, as well as death or injury. Accidents often occur. In addition, there are many cases of traffic accidents due to the driver's instantaneous inadequate response while driving, including attempting to cut into another vehicle or interrupting a career. In particular, in the above situation, the higher the speed of the vehicle, the longer the braking distance is, so the accident that occurs during high-speed driving leads to a large accident. Accordingly, the highway is inducing to maintain a safety clearance distance of 100m at a speed of 100km / h, and to maintain a safety clearance distance of 110m at 110km / h. On the other hand, in addition to the accidents occurring during the driving, accidents often occur when a vehicle, motorcycle or bicycle collides from the rear when the door is opened to get off at the roadside, in which case the occupant enters the rear blind spot when getting off. Due to the lack of confirmation of the situation or inadvertent due to the negligence of the situation in many cases, the left side or the right turn, such as due to the lack of confirmation of the front situation, such as car collision and collision accidents often occur do.

On the other hand, in recent years, the use of navigation information devices such as GPS and navigation has become more common, so it is possible to help the driver safely by finding the camera location and road information in real time while driving. They are notified of the distance or rear situation with other vehicles or have no control of accidents, so safety is greatly reduced.

Therefore, the present invention has been invented in view of the above-mentioned conventional problems, and in particular, it is possible to clearly check and maintain the distance between the vehicle and the vehicle in front of the vehicle while driving suddenly (for example, sudden interruption or When a situation such as a sudden stop of the front vehicle cannot be predicted.) When the occurrence of the vehicle itself, the brake itself is automatically touched once so that the vehicle speed can be reduced instantaneously, inducing the driver to recognize the situation and respond quickly, including collision accidents. It helps to prevent traffic accidents, and at the same time, the situation of the front car becomes clearer in the direction of travel even when the vehicle is left and right turned and the door is opened, so that other vehicles such as motorcycles and bicycles approaching from the rear can be detected quickly and smoothly. Preventing safety accidents in advance, while driving or stopping Prevention of accidents in advance and at the same time before the haryeoneunde safe driving is done so with purpose.

The present invention can check and control the distance between the safety car and the vehicle in proportion to the speed of the vehicle while driving, and when the accident occurs in the straight or left and right turning process, the brake pedal is instantaneously automatically touched once and the driver is clearly aware of the situation. At the same time to reduce the speed to prevent accidents, and also to make the rear sense easy to ensure that even when the occupant is going to get off very safe.

Hereinafter, the configuration of the present invention in more detail.

As shown in FIG. 1, the present invention is equipped with a laser sensor (LS) consisting of a laser transmitter (LD) and a laser receiver (LR) in a predetermined position in the center of the front of the vehicle, and ultrasonic waves on the front left and right or left and right corners of the vehicle, respectively. An ultrasonic sensor S1 consisting of the transmitter SD1 and the ultrasonic receiver SS1 is installed, and an ultrasonic sensor S2 composed of the ultrasonic transmitter SD2 and the ultrasonic receiver SS2 is mounted on both sides of the rear of the vehicle. When attempting to open the ultrasonic sensor (S2) consisting of the ultrasonic transmitter (SD2) and the ultrasonic receiver (SS2) to detect a bicycle or motorcycle or a vehicle approaching from the rear. The laser transmitter LD and the laser receiver LR, and the ultrasonic sensors S1 and S2 including the ultrasonic receivers SD1 and SD2 and the ultrasonic receivers SS1 and SS2 are controllable in the vehicle, but the main controller Send data to the main controller and RF, or send data to the wire. In addition, the GPS receiver and the antenna integrated module are used to detect the vehicle speed and to detect the distance with the vehicle in front of the vehicle while driving by using a GPS or navigation. In addition, the main sensor (Main Control), the laser sensor (LS) is installed together with the GPS system, in this case by installing an LCD to display the distance between the current vehicle speed and the front vehicle to facilitate visual confirmation. The laser sensor LS may be selected to be capable of detecting 200 m ahead of the vehicle, so that the distance between the vehicle and the vehicle in front of the vehicle may be adjusted in low speed or high speed. This is possible.

The ultrasonic sensor S1 installed on the front left and right sides of the vehicle may preferably use a measuring distance of 1 to 3 m so as to detect a vehicle or obstacle in front of the vehicle during cornering.

In addition, the ultrasonic sensor (S2) is installed at a predetermined position in the rear of the vehicle is used to install the measuring distance of 1 ~ 30m, but the sensor is installed on the handle to operate the moment to hold the handle to open the door to move the moving object within 20m rear It acts to sense. Also, in this case, when the reverse gear is inserted to reverse the vehicle, an object within 1 to 2 m in the rear can be detected to maximize safety when reversing.

The present invention configured as described above is very close to the near distance by detecting the distance between the vehicle in front of the vehicle, the obstacle and the front vehicle when detecting the left and right, and detecting the distance, the car, motorcycle, bicycle, people approaching from the rear when the door is opened. The closer you get to the ground, the faster you can hear the sound of audible alarms, voices, etc., as well as the ability to detect rear obstacles when you back up, and suddenly threaten the distance between safety vehicles. When the brake is momentarily touched once, the speed decreases and the driver can recognize the situation at the same time. In particular, the present invention controls the above-described functions through the main controller, wherein the detection situation may be confirmed by the LCD of the main controller or at the same time by the satellite navigation device (GPS) or navigation.

That is, while driving, the laser sensor LS detects the distance to the vehicle in front of the vehicle very effectively. In this case, the laser sensor LS can detect up to at least 200m in advance, so that the vehicle ahead of the road even on a high-speed road such as a highway Up to 200m distance can be easily detected.

In other words, the speed of the subject vehicle in the course of driving on the road can be checked not only on the instrument panel but also on the LCD of the main controller. In addition, since the distance between safety vehicles is set in proportion to the velocity of the subject vehicle, the subject vehicle speed is 100 km / h. In this case, when the distance between the car ahead is within 100m, a beep will sound and a warning signal will be given according to the safety car distance (the safety car distance may be input by the driver).

On the other hand, in a sudden situation where the distance between safety vehicles is reduced to less than 50% instantaneously during the process of detecting the distance between the vehicle ahead and lane change, sudden stop, and dangerous interruption while driving. By this signal, the hydraulic cylinder operates once at a moment to touch the brakes, which not only greatly reduces the speed of the vehicle but also automatically recognizes the emergency situation to the driver, thus preventing safety accidents in advance. Will be generated.

In addition, the ultrasonic sensor (S1) consisting of the ultrasonic transmitter (SD1) and the ultrasonic receiver (SS1) is connected to the direction indication lever of the vehicle to act diagonally in the direction of rotation in the process of turning left or right turn left in the driving process Alternatively, if the direction indication lever is operated left or right to change direction to the right, the switch is connected to enable the distance and control of the vehicle in front of the direction change process.

In other words, when the direction indication lever is operated to the left or right side, the ultrasonic sensor S1 of the direction in which the direction indication lever acts operates to automatically detect the presence of an obstacle or a vehicle in the direction to proceed and send a signal to the driver. By giving them, you can prevent eye loss in advance.

In addition, the ultrasonic sensor (S2) for sensing the rear consisting of the ultrasonic transmitter (SD2) and the ultrasonic receiver (SS2) is connected to the inner handle of the front and rear doors of the vehicle, the rear detection at the moment to pull the handle to open the door Make it possible.

That is, after the vehicle stops, as soon as the occupant grabs the door handle, the sound wave sensor (S2) operates to detect a motorcycle, vehicle, bicycle, or pedestrian within 10 m of the rear to generate a beep or sound. By doing so, the driver and driver will be aware of the situation.

In addition, if the reverse gear is put in order to reverse in the above case, the ultrasonic sensor (S2) will be able to detect obstacles within the rear 1 ~ 2m, and thus will be guided to safely reverse.

In particular, the ultrasonic sensors (S1, S2) is a dial tone, a warning sound or a voice signal as close as the distance closer to the set distance in the process of detecting and detecting the distance from other vehicles, such as motorcycles or bicycles running from the front vehicle or the rear It is desirable to make the driver and passengers more easily recognized. In this process, if the detection distance gets closer, the tone of the dial tone or warning sound increases as the distance gets closer, or if it becomes faster, the situational recognition becomes more reliably audible. The higher the awareness, the more effectively it can contribute to the prevention of safety accidents.

In addition, the present invention is equipped with a small hydraulic cylinder using the vehicle's own hydraulic pressure on the brake of the vehicle to generate a sudden situation (for example, sudden interruption of the other vehicle, lane change, sudden stop, etc.) occurs during driving When the laser sensor (LS) or the ultrasonic sensor (S1) detects a situation and sends a signal to the main controller, by operating the small hydraulic cylinder in the main controller momentarily, the rod is moved back and forth once and the brake is touched once. In addition to deceleration, the driver is clearly aware of the situation.

On the other hand, in the present invention, the driver can input the safety clearance distance while driving so that the driver can safely drive in consideration of his own driving habit, or the distance between the vehicle and the front vehicle is automatically calculated in proportion to the speed of his vehicle. It can be done.

That is, by applying the safety distance step by step based on the own vehicle speed (for example, when the own vehicle speed is 100km, the distance between cars can be set to 100m, 50m, 25m, 12.5m, etc.) It can be set selectively in consideration of driving habits, or the distance between the vehicle and the vehicle in front of the vehicle is automatically adjusted based on the speed of the vehicle. It can be generated.

More specifically, the speed and the distance are proportionally set at the same time, and the speed and the distance between the distances can be set by the user. In the event of an accident that causes a dangerous situation to be interrupted, an urgent alarm sound is generated or a momentary automatic touch is applied to the driver to reduce the speed of the vehicle, while at the same time allowing the driver to be alert or defensive. In addition, when the door is opened to get off, it detects motorcycles, bicycles or other vehicles running from the rear to prevent safety accidents when the door is opened. It is a very useful invention that can contribute.
