Abstract

PURPOSE: A system for preventing a collision between a vehicle and an obstacle is provided to prevent the loss of lives and property due to the non-security of a safety distance during a travel or parking by informing a driver of the approach of a vehicle or an obstacle. CONSTITUTION: A system for preventing a collision between a vehicle and an obstacle comprises a vehicle speed sensor(1) to detect the traveling speed of a vehicle, a vehicle distance sensor(2) to detect the distance between vehicles and a vehicle and an obstacle, a control unit(3) to generate a driving signal to an alarm generating buzzer(5) and an alarm lamp(4) if a danger of a collision is decided, and the alarm lamp lighted on/off or blinking with response to the output signal of the control unit. An alarm off switch(6) is added to the input terminal of the control unit. While the alarm off switch is in the off switch, a traveling speed in proportion to the distance between vehicles and a vehicle and an obstacle is calculated. Depending on the calculated distance, a driving signal is generated.

Description

Collision prevention apparatus between vehicles and obstacles {vehicle and object collision prevention apparatus}

The present invention relates to a collision avoidance device between vehicles and obstacles. More specifically, the vehicle safety is detected by detecting a distance and a traveling speed with a vehicle in front of the vehicle while driving or parking and promptly alerting a collision if there is a possibility of collision. It is invented to prevent the collision caused by the lack of distance in advance.

Conventional vehicles are equipped with a device for alarming when the safety distance with the object behind or behind the vehicle is not secured, but when the safety distance with the vehicle in front is not equipped with a device that can detect and alarm In addition, the driver must recognize the distance to the vehicle with his own eyes and implement safe driving.

However, when driving at high speed for a long period of time, the driver often unconsciously gets too close to the vehicle in front of the driver unconsciously. Often drivers do not respond immediately and cause a crash.

The present invention has been made to solve such a conventional problem, the driver detects the distance and the driving speed with the vehicle in front of the vehicle while driving or when the driver immediately alerts when approaching close enough that there is a risk of collision. Inter-vehicles and obstacles that can prevent personal injury and property damage from collision accidents by securing a safe distance from the vehicle ahead according to the speed (ie, by allowing defensive driving). The object is to provide a collision avoidance device.

An object of the present invention as described above, the vehicle speed sensor for detecting the traveling speed of the vehicle by an electric signal; An inter-vehicle distance sensor installed at the front bumper of the vehicle and detecting the distance to the front vehicle or a specific object as an electric signal; An alarm cancel switch for selectively canceling driving of the inter-vehicle warning system; When the alarm release switch is in the "off" state, the output signals of the vehicle speed sensor and the inter-vehicle distance sensor are continuously input to calculate the safety distance for each driving speed relative to the distance between the vehicle in front of the vehicle and a specific object so that the distance compared to the current driving speed is increased. A controller for generating a driving signal to the alarm lamp and the buzzer for generating an alarm sound when it is determined that there is a fear of collision; An alarm lamp which is turned off or flashes in response to an output signal of the controller; This can be achieved by configuring a buzzer for generating an alarm sound which is driven or not driven in response to an output signal of the controller.

Therefore, if the distance between the vehicle in front of the current driving speed is close enough to cause a collision while driving or parking the vehicle, the lamp and the buzzer are automatically driven so that the driver immediately recognizes it and the safety distance between the vehicle and the object according to the current driving speed. It is possible to prevent accidents caused by collisions due to the inability to secure safety distances, which can prevent human and property damage.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Figure 1 shows a block diagram of the device of the present invention, Figure 2 shows a schematic diagram of a vehicle showing the operating state between the vehicle and the vehicle is installed the device of the present invention.

According to this, the vehicle speed sensor (1) for detecting the driving speed of the vehicle as an electrical signal;

An inter-vehicle distance sensor (2) installed in the front bumper (7) of the vehicle and detecting the distance to the front vehicle or a specific object as an electrical signal;

The vehicle receives the output signal from the vehicle speed sensor 1 and the vehicle distance sensor 2 and calculates a safety distance for each vehicle's driving speed relative to the distance between the vehicle and a specific object through a predetermined program to calculate the safety distance of the vehicle ahead of the current driving speed. And a controller 3 for generating a driving signal to the alarm lamp 4 and the buzzer 5 for generating an alarm sound when the distance from the object is determined to be collided with the object.

It is characterized in that the basic configuration is composed of an alarm lamp (4) that is turned off or flashing in response to the output signal of the control unit (3).

In addition, the apparatus further includes a buzzer 5 for driving or deactivating an alarm sound generated in response to an output signal of the controller 3 or driving the inter-vehicle distance warning system at an input of the controller 3. An additional alarm disengagement switch (6) can be selectively installed to allow the control unit (3) to set a safety distance for each driving speed relative to the distance between the vehicle in front of the vehicle and a specific object only when the alarm disengagement switch (6) is "off". It is an additional feature to enable the calculation.

Referring to the operation and effect of the device of the present invention configured as described above are as follows.

First, in the control unit 3 which performs an overall control function for various electric appliances installed in the vehicle through a predetermined program in the normal time, the alarm release switch 6 operated by the driver in the normal time is "on" or "off". It is determined whether the safety distance for each driving speed is calculated based on the distance between the vehicle in front of the vehicle and a specific object.

That is, when the alarm cancellation switch 6 is in the "on" state, the front vehicle and the specific object only are in the "off" state without calculating a safety distance for each driving speed relative to the distance between the vehicle and the specific object. It calculates the safety distance for each driving speed compared to the distance between and and outputs a control signal corresponding to the result.

On the other hand, when the control unit 3 confirms the state of the alarm release switch 6, and is in the "off" state, the output signal of the vehicle speed sensor 1 which detects the driving speed of the vehicle as an electric signal is received at the same time. Installed in the front bumper (7) of the vehicle to continuously receive the output signal of the inter-vehicle distance sensor (2) to detect the distance to the front car or a specific object as an electrical signal, the distance between the front vehicle and the specific object through a predetermined program The safety distance for each vehicle's speed is calculated.

As such, when the controller 3 detects the distance between the vehicle in front of the vehicle and the object according to the driving speed of the current vehicle, the driver unconsciously excessively approaches the vehicle in front of the vehicle (ie, does not secure the safety distance compared to the current driving speed). If it is determined that there is a concern, the driving signal is generated in the alarm lamp 4 and the buzzer 5 for generating the alarm sound.

Therefore, when the alarm lamp 4, which is operated in response to the output signal of the control unit 3, is in a collision, the driver blinks automatically and at the same time, an alarm sound is generated from the alarm buzzer 5, so that the driver is visually alerted. And through hearing and immediately aware that there is a risk of collision with a particular object in front of the front car or own vehicle, it is possible to immediately secure a safety distance by reducing the running speed or by operating the brakes.

On the other hand, for example, a method of comparing the distance and the driving speed with the front vehicle while driving the vehicle, for example, when the safety distance with the front vehicle is 60-70m per hour while driving at 70 km / h, the warning lamp (4 ) And the buzzer 5 for alarm sound generation may be driven. When parking, the distance to the front obstacle may be driven when the distance is close to a predetermined distance (for example, 1 m / 0.5 m / 0.3 m).

Of course, as described above, when the vehicle is driven or parked, the distance between the vehicle and the driving speed are detected so that the alarm lamp flickers or the buzzing sound itself is disturbed. "Disables the feature automatically.

As described above, according to the present invention, when the distance between the vehicle in front of the current driving speed is close enough to cause a collision while the vehicle is being driven or parked, the alarm lamp and the buzzer are driven automatically. Anytime, anywhere, it can be recognized immediately and secure a safe distance from the vehicle ahead and the object according to the current driving speed, which can lead to a collision accident due to the inability to secure a safe distance, which can prevent human and property damage.
