An embodiment of the present invention is to divide a road on which an online electric vehicle travels into segments, and to arrange switches and position sensors used for on / off control of each segment in consideration of the speed of the vehicle. .

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

2 is a diagram illustrating a segment-based online electric vehicle power feeding method according to an embodiment of the present invention.

Referring to FIG. 2, unlike the conventional art of FIG. 1, a road in which a feed line is embedded may be divided into segments 200, and a switch corresponding to each segment 200 may be provided.

When the feed road is divided into segments 200 having a predetermined length as described above, the installation and construction of the feed road are not only easy, but also the segment on which the online electric vehicle is located through the on / off control of the switch. By only supplying power to the (200), it is possible to protect the general vehicle or pedestrians from magnetic fields, not the online electric vehicle. In addition, when performing the on (on) / off (off) control of the segment 200 through the precise position recognition, it is possible to reduce the wasted power to improve the power supply efficiency.

3 is a diagram illustrating waveforms of a power supply according to a time point of turning on a segment according to an exemplary embodiment of the present invention.

Referring to FIG. 3, a time delay occurs when sufficient power is supplied to a segment according to a transient response phenomenon of an electrical signal, and the horizontal axis of the graph is time and vertical axis. May be a value corresponding to the strength of the power supply such as voltage and current.

In the ideal case, as in (a), there is no transient response of the electrical signal, and as soon as the segment is powered on, sufficient power is supplied to the segment. In this case, there is no problem in power delivery to the vehicle even when the segment is turned on the moment the on-line electric vehicle enters the segment. However, as in (b), unlike the ideal case of (a), in actual cases, there is a transient response in the electrical signal, so this model cannot be applied as it is.

In the real case as shown in (b), there is a transient response phenomenon of the electrical signal. As soon as power is supplied to the segment, the power supplied to the segment begins to rise, but a certain time delay is required until the power supplied to the segment reaches a sufficient level. Likewise, the power supplied to the segment begins to fall as soon as the power supply to the segment is turned off, but a certain time delay is required until the power supply to the segment is completely disconnected.

In the actual case as shown in (b), if the segment is turned on at the moment the vehicle (OLEV) enters the segment, the segment is not supplied with sufficient power during the delay time during the transient response, and thus, power delivery to the vehicle is problematic. Will occur. This may lead to a reduction in current collection efficiency of the entire online electric vehicle system. Therefore, in the actual case as shown in (b), it is necessary to turn on the power of the segment before the vehicle OLED enters the segment in consideration of the existence of a delay time in supplying the segment to the inverter or the power feeding device.

In the case of turning on the segment in advance as shown in (c), since there is substantially a time delay due to the transient response before the on-line electric vehicle enters the segment, a power of sufficient magnitude is already supplied to the inverter or the power supply when the vehicle enters the segment. The state is applied to the device. Therefore, it is possible to solve the problem of power supply disruption or reduction in current collection efficiency due to time delay in the wireless power transfer of the non-contact magnetic induction method to the vehicle.

4 is a diagram illustrating a power feeding method of an on-line electric vehicle when the segment is turned on in advance according to an embodiment of the present invention. This can be done through power supply control of.

The segment at the rear of the driving electric vehicle is turned off 400, and the segment at which the driving electric vehicle is currently located is powered on 402 so that actual power transfer occurs. In addition, the segment near the front of the driving electric vehicle is powered on (404) in advance, but the actual power transmission does not occur, the segment far away in front of the driving electric vehicle is powered off ( While maintaining the off (406) state, the power may be turned on as the distance to the online electric vehicle becomes closer.

This method has the advantage that no feeding disturbance occurs in the segment at the moment the on-line electric vehicle enters, but has the disadvantage that electromagnetic waves are generated in the on segment beforehand.

For the idea of minimizing the shortcomings of the generation of electromagnetic waves in the pre-on segment, some assumptions can be made.

First, online electric vehicles move by a certain braking distance or stopping distance even if they stop or stop suddenly. Second, there is no human approach within the stopping distance. Third, there is no other vehicle within the stopping distance if the safety distance is maintained. It is a home. Under these assumptions, a position sensor for measuring the current position of the vehicle is arranged to minimize the damage of electromagnetic waves generated when the segment is turned on in advance to control the power supply of the segment when the vehicle reaches the preset position. Can be considered.

5A to 5B are diagrams illustrating a system configuration and a power feeding method of an online electric vehicle when the segment is turned on in advance in front of a predetermined distance according to an embodiment of the present invention.

The constant distance means the distance between the segment and the switch calculated in advance in consideration of the speed limit of the road, the average driving speed of the vehicle, and the delay time due to the transient response of the electric signal. The same applies to all segments when constructing or feeding roads. In the embodiment of the present invention will be described a case in which the segment and the position sensor in a 1: 1 correspondence, this configuration is not limited to this, and various modifications such as N: 1, 1: N of the segment and the position sensor is possible, of course. to be.

FIG. 5A shows a system configuration of a segment and a switch when the segment is turned on before a predetermined distance. Herein, the switch refers to a segment switch that controls on / off of a corresponding segment, and may be implemented by being connected to another device such as a position sensor according to the embodiment and the implemented method. FIG. 5A illustrates a lane in which an online electric vehicle travels from left to right, and the switch is disposed on the left side by a distance from the segment to which the online electric vehicle is connected, and whether the segment embedded in the road located on the right side of the road is powered. (on / off) can be controlled.

FIG. 5B is a diagram illustrating a power feeding method of an online electric vehicle when the segment is turned on before a predetermined distance. When an online electric vehicle travels from left to right, a switch is disposed in the segment in which the online electric vehicle is currently located to control the right segment of the distance to which the vehicle will be located in the future. Thus, if the online electric vehicle is located in the third segment from the current left, the third segment is turned on before the vehicle enters by a switch of the third segment placed in the left segment where the vehicle has already passed. to be.

Similarly, the third segment in which the online electric vehicle is currently located has a switch for controlling the power supply of the sixth segment, so that when the vehicle travels through the third segment, the sixth segment ahead of the driving direction is turned on in advance. (on). Through such a configuration, it is possible to smoothly feed the on-line electric vehicle even in time delay caused by the transient response of the electric signal.

6A-6C are graphs of considerations for determining the distance between a segment and a switch when turning the segment ahead of time in accordance with an embodiment of the present invention.

6A illustrates a change in stopping distance according to the speed of an online electric vehicle. The stopping distance is proportional to the square of the vehicle speed. On the other hand, the road has a minimum driving speed (A km / h) and a maximum driving speed (B km / h), and the stopping distance (C m) at the minimum driving speed (A km / h) of the vehicle is previously turned on (on). The maximum distance of the segment can be determined. The segment switch may be placed at the maximum distance of the segment that can be turned on in advance, determined here.

FIG. 6B is a graph illustrating a change in moving distance during an inverter power supply delay time according to the speed of a vehicle.

Referring to FIG. 6B, assuming that the inverter power supply delay time has a constant value, the moving distance in the meantime is proportional to the vehicle speed. At this time, it can be determined as the minimum distance of the segment that can be turned on in advance, the travel distance (D m) moved to the maximum driving speed (B km / h) of the vehicle during the inverter power supply delay time.

Here, the stopping distance (C m) at the minimum driving speed (A km / h) of the vehicle is greater than the moving distance (D m) moved to the maximum driving speed (B km / h) of the vehicle during the inverter power supply delay time. It must have a value. If not, the feed inverter should be replaced with an inverter with a smaller power supply delay. The stopping distance (C m) at the minimum driving speed (A km / h) of the vehicle is greater than the moving distance (D m) moved to the maximum driving speed (B km / h) of the vehicle during the inverter power supply delay time. If present, the stopping distance (C m) at the vehicle's minimum driving speed (A km / h) is greater than the travel distance (D m) traveled to the maximum driving speed (B km / h) of the vehicle during the delay of the inverter power supply. A value smaller than) can determine the distance that is set between the segment and the switch.

6C is a graph illustrating a change in a predetermined distance and an inverter power supply delay time set between a segment and a switch according to a change in the inverter power supply delay time according to an embodiment of the present invention.

Referring to FIG. 6C, for example, since the stopping distance at the minimum driving speed (60 km / h) of the vehicle is about 30m, the maximum value of the predetermined distance between the segment and the switch is determined to be about 30m. In addition, as the inverter delay possible time is changed from 0.01 sec [sec] to 0.91 sec [sec], the moving distance moved from the maximum driving speed (80 km / h) of the vehicle during the inverter power supply delay time is about 1 m to about 72 m. To change. However, since the moving distance here should be smaller than 30m, which is the above-mentioned stopping distance, in order to design the segment and switch control system when the segment is turned on in advance of the predetermined distance, the maximum driving speed of the vehicle during the delay of the inverter power supply (80 km / It can be concluded that an inverter with an inverter power supply delay time of less than 0.51 seconds [sec] should be used so that the moving distance moved to h) can be less than 30m.

Using the method of turning on the segment in front of a certain distance, it is possible to design the feed road and the segment switch even considering the stopping distance (C m) at the minimum driving speed (A km / h) of the vehicle, and measure the vehicle speed in real time. There is an advantage that can be designed as a relatively simple system without the configuration used for the back.

However, since this method is not an optimized design for an individual vehicle, the feeding efficiency is lower than the method of turning on the segment in advance in consideration of the vehicle speed. In addition, the feeding efficiency is lower when the speed change of the online electric vehicle is faster or faster than the design speed, and the magnetic field exposure may occur when the online electric vehicle moves slower than the design speed. Thus, as another embodiment of the present invention, a method of turning on the segment in advance in consideration of the vehicle speed will be described.

7A to 7C are diagrams illustrating an embodiment of a system configuration and an online electric vehicle power feeding method when a segment is turned on in advance in consideration of vehicle speed according to an embodiment of the present invention.

FIG. 7A is a diagram illustrating a system configuration of a segment and a switch when the segment is turned on in advance in consideration of the vehicle speed.

Referring to FIG. 7A, although segment switches are arranged at regular intervals, it may be confirmed that a specific segment switch does not correspond 1: 1 to a specific segment. Segment switches arranged at regular intervals are connected in real time according to the segment and the situation located at a suitable distance in consideration of the real-time vehicle speed to control the power (on / off), such real-time connection can be changed in real time .

In order to implement such a system, a vehicle speed measuring device and a segment control unit which determine a relationship between a segment and a switch in real time in consideration of the vehicle speed and connect and change them are required. The vehicle speed measuring device may be implemented in various forms such as a device for receiving its own traveling speed transmitted by the vehicle, or a device for directly measuring the traveling speed of the vehicle.

Meanwhile, the segment control and the switch connection of the segment controller may use a table lookup method to implement real-time calculation in the process of turning on the segment in consideration of the length of the segment and the inverter performance.

In the embodiment of the present invention, the distance between the segment and the switch may be used differently from the considerations of FIG. 6. The stop distance (E) at the current travel speed of the online electric vehicle and the travel distance (F) at which the vehicle moves at the current travel speed during the inverter power supply delay time, and the distance between the segment and the switch is the inverter power supply delay. It is determined to be larger than the moving distance F at which the vehicle travels at the current driving speed for a time period and smaller than the stopping distance E at the current driving speed of the vehicle.

FIG. 7B is a diagram illustrating a power feeding method of an on-line electric vehicle when the segment is turned on in consideration of the vehicle speed in advance.

Referring to FIG. 7B, since the online electric vehicle is currently located in the third segment from the left, and the vehicle speed is slow, the switch disposed in the third segment is set to be connected to the fifth segment. Accordingly, the fifth segment is turned on when the vehicle passes the third segment, and when the vehicle passes the fifth segment, the power supply inverter installed in the fifth segment passes the delay time and has sufficient power for the vehicle. The state can be supplied.

FIG. 7C is a diagram illustrating a power feeding method of an online electric vehicle when the segment is turned on in advance in consideration of the vehicle speed.

Referring to FIG. 7C, since the on-line electric vehicle is currently located in the third segment from the left, and the speed is high, the switch disposed in the third segment is set to be connected to the eighth segment. Accordingly, the eighth segment is powered on when the vehicle crosses the third segment, and when the vehicle passes the eighth segment, the power supply inverter installed in the eighth segment passes a delay and has sufficient power for the vehicle. The state can be supplied.

As such, the method of turning on the segment in advance in consideration of the vehicle speed has an advantage of good feeding efficiency since the design is optimized for the individual vehicle.
