Description

Method of controlling a navigation system

The present invention relates to a navigation system control method, and more particularly, to a navigation system control method for protecting a vehicle and a passenger by guiding the speed of entry of the speed bumps.

In general, the vehicle is equipped with a variety of devices to help the driver, in particular, navigation using the GPS (GPS: Global Positioning System) is mounted on the vehicle to provide directions to the driver to the destination.

GPS navigation system is designed to allow multiple satellites to orbit above 20200KM and receive radio waves from at least three satellites at any location in the world.

That is, the navigation system receives radio waves representing latitude, longitude, altitude, etc. from a plurality of satellites, calculates the current position of the vehicle, and outputs map information in which the current position is stored to the driver. It also calculates the change in the position of the vehicle and outputs the speed of the vehicle to the driver.

Therefore, when the driver registers the destination to be arrived, the navigation system calculates the driving distance to the current location and the destination, and derives and outputs the optimum route accordingly, so that the driver drives according to the output and precisely reaches the destination. You can arrive.

In addition, the navigation outputs the position information of the speed bump to the driver. Therefore, the driver detects the presence of the speed bump in the front of the vehicle's moving direction to induce deceleration driving.

However, the conventional navigation only informs the presence or absence of the speed bump in front of the vehicle's moving direction. Therefore, even if the vehicle enters the speed bump at an excessive speed, the navigation does not give any warning or safety speed, causing the speed bump to be excessively excessive, causing damage to the vehicle or reducing the speed more than necessary to hinder traffic flow. there was.

The problem to be solved by the present invention relates to a navigation system control method for providing a driver with a safe speed in each speed bump and outputting a warning when driving at a speed greater than the safe speed to prevent damage to the vehicle and injury to passengers. .

Referring to FIG. 1, a navigation system according to an embodiment of the present invention includes a controller 110, a data unit 130, a detector 120, an output unit 140, and an input unit 150.

The sensing unit 120 includes a vehicle position detecting unit 121 and a vehicle speed detecting unit 122. The vehicle position detecting unit 121 receives accurate vehicle position data from a satellite through a satellite navigation system such as GPS or GLONASS and transmits the position data of the vehicle to the controller 110 to be described later.

The vehicle speed detector 122 detects the speed of the vehicle in real time or periodically when the vehicle moves, and transmits the speed data of the vehicle to the controller 110 to be described later. The vehicle speed detector may detect the speed of the vehicle or the speed from the speedometer of the vehicle after calculating the change of the position of the vehicle from the position data received from the vehicle position detector.

The data unit 130 may store speed bump data, vehicle data, and dangerous speed data. It also performs a function of storing data input by the input unit 150 to be described later.

The speed bump data includes height and width data divided by position, curvature, and a predetermined unit of the speed bump, and is transmitted to the controller 110 to be described later.

The controller 110 calls the detected speed bump data and vehicle data previously stored in the data unit 130 (S220). The speed bump data includes the curvature of the speed bump and the height and width divided by the predetermined unit. Vehicle data includes the type and weight of the vehicle.

The controller 110 calls the stored speed bump data and the pre-stored safety speed data corresponding to the vehicle data (S230). The called safety speed is the curvature of the called speed bump, the height and width divided by the predetermined unit, and the call. Corresponds to the type and weight of a vehicle.

The controller 110 determines whether the speed of the vehicle received from the vehicle speed detector 122 is greater than the called safety speed. If large, the output unit 140 instructs the output unit 140 to output a warning and a safe speed to the driver.

The output unit 140 outputs a warning and a safe speed to the driver through video and audio.
