Abstract

The present invention measures the speed of a driving vehicle and controls the speed of the vehicle according to the speed limit information provided from the traffic information center. In case of overspeed, the speed of the vehicle can be forcibly limited within the speed range regardless of the driver's will. It is about a device which makes it.

The present invention is connected to the hinge bracket installed at one end of the accelerator pedal and one end of the hinge bracket to provide a force against the pressing pressure of the accelerator pedal by receiving tension from the outside and connected to the cable and the stationary range of the DC motor It is composed of a tension control device for adjusting the tension of the cable to receive the rotational power, the tension control device is connected to the worm and worm gear and the shaft of the worm gear installed on the shaft of the DC motor is connected to the cable according to its rotation operation A pulley that adjusts tension by pulling or unwinding is provided with a spur gear on one side thereof to be engaged with the worm gear, and consists of a potentiometer for detecting a load on the worm gear depending on whether the cable is wound.

The speed limiting device composed of the above components inputs the speed limit for each road section sent from the traffic information center to the central processing unit in the vehicle through the roadside antenna and the RF transmitting / receiving module of the vehicle and reads it from the speed measuring device inside the vehicle. The speed limit is determined by checking whether the vehicle is overspeed, and if the speed is not reduced even after the warning signal is sent, a control signal for controlling the speed of the vehicle within the speed limit is output to the driving device to limit the speed. If the speed limit device is in operation, the driver judges it as an emergency and needs to increase the speed of the accelerator pedal to overcome the repulsion pressure of the cable itself. Due to its elasticity, it is possible to further increase speed up to a certain speed.

The present invention configured as described above recognizes the driver first when the vehicle is speeding over the specified speed in all road sections, and if the speed is still maintained, it is converted to the speed limit mode regardless of the driver's will. It is possible to reliably limit the speed limit by depressing the pressure of the accelerator pedal. Accordingly, it is possible to prevent overspeed by the driver's unconsciousness, thereby preventing a large traffic accident due to the speed, and to realize the intelligent transportation system early by improving the driver's comfort and travel satisfaction.

Description

Speed limiter of vehicle using cable {APPARATUS FOR SPEED LIMIT OF VEHICLE USING CABLE}

The present invention relates to a speed limiting device of a vehicle, and more particularly to a speed limiting device of a vehicle for forcibly limiting the speed of a vehicle running at an excessive speed in a danger zone of a road regardless of a driver's intention.

In recent years, the development of automobiles, along with the development of road networks, has changed the way people live and live. However, with the proliferation of vehicles, many side effects of the road traffic era have begun to emerge, and new traffic engineering approaches are required. As part of the new approach, there is a desire to develop intelligent transportation and vehicles.

On the other hand, the speed limit method used so far is that the speed limit of the road is set differently according to the highway, national road, city road, and each section, and the driver has adjusted the speed by looking at the speed limit sign on the road. However, in case of road signs indicating such speed limits or dangers, it is difficult for the driver to keep a constant attention on the road signs while driving, so it is often difficult to recognize the speed limit, construction and accident warning signs carefully. As a result, the driver is involuntarily violating speed. These speed violations cause traffic accidents such as central line invasion, collision with the front car, derailment on the curve and collision with the guide rail. In addition, in order to prevent traffic accidents caused by speeding, a deceleration is induced through the use of an unmanned enforcement camera or a police officer. There is a problem without a way.

Therefore, the present invention was devised to solve the above-mentioned problems, and measures the speed of the currently running vehicle and controls the vehicle speed according to the speed limit information provided from the traffic information center to speed the driver when the vehicle is overspeed. Alerts the driver to force the vehicle speed to be within the speed limit regardless of the driver's will, and if the driver himself decides to be in an emergency even when changing to the speed limit mode, press the pedal harder to increase the speed. It is an object of the present invention to provide a speed limiting device for a vehicle.

Figure 2 is an embodiment of a speed limiting device of the present invention.

In order to achieve the above object, the present invention inputs a speed limit for each road section sent from a traffic information center to a central processing unit through a roadside antenna and an RF transmission / reception module of a vehicle, and is operating by using a speed measurement device inside the vehicle. After reading the speed of the vehicle, it is judged whether it is overspeed by comparing with the reference speed limit, and if it is determined that the speed is over, the speed controller is operated to prevent the pressure of the accelerator pedal from being pressed.

1 is an overall schematic view of a speed limiting device mounted on a vehicle in the present invention, in the present embodiment is mounted on the wheel portion of the vehicle and the speed measuring device (2) for detecting the rotational speed of the wheel to measure the traveling speed and the traffic The speed limit information transmitted from the information center to the roadside antenna is compared to the central processing unit in the vehicle through the roadside antenna and the RF transmission / reception module in the vehicle to determine whether the vehicle is overspeed. Inform them. If the driver is informed of the overspeed situation and the speed is not reduced, the speed limiter 3 is activated.

Figure 2 is an embodiment of the speed limiting device 3 of the present invention, as shown in the hinge bracket 12 installed on one end of the accelerator pedal 11, and connected to one end of the accelerator pedal to tension from the outside The cable 10 provides a counter force against the pressing pressure of the accelerator pedal, and is connected to the cable 10 to receive the forward and reverse rotational power of the DC motor 5 to adjust the tension of the cable 10. It consists of tension control device. Here, the tension control device is connected to the worm (6) and the worm gear (7) installed on the shaft of the DC motor (5), and the shaft of the worm gear (7) to the cable 10 in accordance with its rotational operation Pulley (4) to adjust the tension by pulling or loosening, and the spur gear (8) is provided on one side thereof to be engaged with the worm gear (7), the worm gear (7) depending on whether the cable 10 is wound It consists of a potentiometer (9) for detecting the load applied to the cable, and the cable (10) has its own tensile force, so when the driver determines that an emergency situation, even if the speed limiter (3) is in operation can be overcome the tension of the cable If you apply enough to the speed up to a certain speed can be configured to increase.

The present invention described above is capable of various substitutions, conversions, and modifications within the scope without departing from the technical spirit of the present invention for those of ordinary skill in the art belonging to the above-described embodiments and attached It is not limited by the drawings.

According to the present invention, the driver first recognizes the driver when the vehicle is speeding over the specified speed while driving on the road, and if the driver continues to overspeed, the vehicle switches to the speed limit mode regardless of the driver's will. By depressing the pressure of the accelerator pedal, it is possible to reliably limit the speed limit and to increase the speed in case of emergency. Accordingly, it is possible to prevent overspeed by the driver's unconsciousness, thereby preventing a large traffic accident due to the speed, and to realize the intelligent transportation system early by improving the driver's comfort and travel satisfaction.
