Description

Autonomous vehicle system {SYSTEM OF SELF DRIVING CARS}

The present invention relates to an autonomous vehicle system, and more particularly, to an autonomous vehicle system that allows exposure to advertisements using a waypoint.

An autonomous vehicle is a vehicle that can drive automatically without human driving. Autonomous vehicles drive autonomously by recognizing their surroundings using radar, light detection and ranging (LIDAR), GPS, and cameras and specifying a destination. Unmanned vehicles that are already being put into practical use include unmanned vehicles that patrol preset routes operated by the Israeli military, and unmanned driving systems such as dump trucks operated in overseas mines and construction sites.

The first core technologies of these autonomous vehicles are the driverless vehicle system and the actual system. It is a technology that not only simulates in the laboratory, but also actually builds an unmanned vehicle system. It implements the accelerator, reducer and steering device, which are driving devices, to suit unmanned operation, and enables control using the computer, software and hardware installed in the unmanned vehicle. do.

The second core technology is to receive and process visual information using vision and sensors. As the basis of autonomous driving for unmanned operation, it is a technology that accepts image information and extracts necessary information from the image. It uses not only CCD (charge-coupled device) cameras but also ultrasonic sensors and range filters to fuse information necessary for distance and driving, so that it can avoid obstacles and cope with unexpected situations through analysis and processing.

The third core technology is the integrated control system and operation monitoring fault diagnosis system technology. This technology establishes a driving monitoring system that monitors vehicle operation and gives appropriate commands according to changing situations, and provides appropriate information to the operator by diagnosing system failures by analyzing various situations occurring from individual processors and sensors. or to perform the function of notifying an alarm.

The fourth core technology is intelligent control and intelligent operation devices. This technology is an unmanned driving technique that generates control commands based on mathematical analysis using real vehicle models. Intelligent Forward Control is a system that maintains the distance from the vehicle in front or obstacles by adjusting the speed by itself without the driver operating the pedals based on radar guide technology. When the driver inputs the distance to the vehicle in front, the long-distance radar attached to the front of the vehicle detects the position of the vehicle in front, maintains a constant speed, decelerates or accelerates, and stops completely if necessary, which is useful in weather where visibility is difficult.

The fifth applied technology is the lane departure prevention system. This is a technology that notifies the driver of an unintended departure situation by detecting the lane with a camera installed inside.

The sixth application technology is the parking assistance system. This is a system that helps the car park in reverse by adjusting the steering system when the driver finds the assist button, puts in reverse gear, and presses the brake pedal. By automatically guiding the vehicle from the departure point to the parking space based on infrastructure as well as vehicle-mounted sensors, it saves unnecessary time and energy when parking, thereby minimizing cost and environmental pollution.

The seventh application technology is the automatic parking system. This is a technology in which the driver stops the car in front of the parking lot, turns off the engine, gets off, and presses the remote control lock switch twice in succession. am.

The eighth application technology is a blind spot information guidance system. This is to warn the driver by judging whether there are other vehicles in the blind spot that cannot be seen through the side mirrors by sensors mounted on both sides of the car. .

The biggest advantage of driverless cars is that they help fuel efficiency by avoiding repeated stops by making the control device more even because the driving speed and traffic management data match. will be. In addition, it has the advantages of solving fatigue caused by long-term driving, greatly reducing the risk of traffic accidents, speeding up road traffic flow, and reducing traffic congestion.

When such autonomous vehicles are used, future advertising business is expected to take place in a completely different structure. Since autonomous vehicles do not have a driver, personalized advertisements can be provided and these advertisements can be shared more. Therefore, it is time to develop an advertisement model for an autonomous vehicle that provides a new user experience in the future.

Hereinafter, the autonomous vehicle system 1000 according to an embodiment of the present invention will be schematically described. 1 is a diagram schematically illustrating an autonomous vehicle system according to an embodiment of the present invention.

As shown in FIG. 1 , the system 1000 of an autonomous vehicle according to an embodiment of the present invention calculates an initial route R1 when setting a destination D in the autonomous vehicle 100, In the route R1, a waypoint s1 for advertisement exposure or customer inflow is searched, or other waypoints s2, s3, and s4 separated from the initial route R1 are searched.

In this case, the user may select a waypoint s1 existing on the route or s2 that is slightly spaced apart, and may select a plurality of waypoints s3 and s4 that are a little further apart.

If a waypoint exists outside the initial route, the arrival time of the destination may be increased. Therefore, in this case, the autonomous vehicle system according to the present embodiment reduces the vehicle use fare or provides a separate benefit to the user in return for the time delay.

At this time, since the server 200 is provided with an advertisement database according to each waypoint, it can transmit related advertisements after the user arrives at the waypoint or while driving toward the waypoint. That is, the self-driving vehicle system according to the present embodiment aims to maximize the advertising effect by setting the advertisement itself as a waypoint that is a geographical location and direct inflow of customers to the waypoint in addition to the traditional one-way advertisement exposure.

Hereinafter, an autonomous vehicle system according to an embodiment of the present invention will be described in more detail. 2 is a configuration diagram of an autonomous vehicle system according to an embodiment of the present invention, FIG. 3 is a configuration diagram illustrating the sensing unit in FIG. 2 in more detail, and FIG. 4 is a diagram illustrating the output unit in FIG. 2 in more detail. It is a configuration diagram, and FIG. 5 is a configuration diagram illustrating the server in FIG. 2 in more detail.

First, referring to FIG. 2 , the system 1000 for confirming getting on and off according to an embodiment of the present invention includes an autonomous vehicle 100 and a server 200 .

In this embodiment, the autonomous vehicle 100 is set as an unmanned pay transportation means for paying a fare, and the input unit 110 , the sensing unit 120 , the output unit 130 , the control unit 140 , the communication unit 150 and the and a driving unit 160 . On the other hand, the input unit 110 and the output unit 130 here are of course also possible to implement a function through a separate user terminal (200).

That is, the input unit 110 serves to input the destination of the autonomous vehicle, and may be connected to the user terminal 200 authenticated through the communication unit 150 to input the destination. The output unit 130 to be described later is also the same. According to the input destination, the controller 140 derives the initial driving route and the modified minimum time or minimum distance route. Furthermore, the controller 140 searches for at least one waypoint distributed on the route or spaced apart from the route based on the data received from the server 200 so that the display unit to be described later outputs it.

Referring to FIG. 3 , the sensing unit 120 may include a radar 121 and a lidar 122 , and may further include a camera 123 . The radar 121 refers to a device capable of moving unmanned while performing a radar detection operation by mounting an antenna in an autonomous vehicle. The radar 121 is not limited to performing only a radar detection operation using the provided antenna, and such as a plurality of sensors or complex sensors capable of sensing the surrounding environment, such as the lidar 122 and the camera 123 . It can be implemented in the form In addition, the radar 121 generates surrounding sensing information by sensing the surrounding environment, and determines inanimate objects such as roads, other vehicles, people, and buildings that are obstacles in the driving direction based on the surrounding sensing information.

The lidar 122 is a device that precisely draws a surrounding state by emitting a laser pulse, receiving the light reflected from the surrounding target object, and measuring the distance to the object. The lidar 122 emits a laser pulse to the ground surface and measures the return time by analyzing the spatial position of the reflection point to measure the topography, and the reflected return time is different depending on the structure. A difficult three-dimensional model can be obtained.

The lidar 122 is composed of a laser, a scanner, a receiver, and a positioning system, and the wavelength of the laser is 600-1000 nm. The scanner is the part that lets you quickly scan your surroundings to get information. The receiver is a part that detects the returning light, and the sensitivity to the light of the receiver is a major factor influencing the performance of the lidar 122 .

In addition, since the sensing unit 120 needs to utilize the location information of the autonomous vehicle, it essentially further includes a GPS 124 , and a microphone 125 to intervene in autonomous driving with a voice or the like even if the passenger does not perform a steering operation. may be further provided.

The biometric information sensor 126 not only prepares for an emergency by sensing the occupant's heartbeat, pressure, brain waves, etc., but also detects fingerprint and iris information when entering and exiting the vehicle to prevent erroneous boarding.

Referring to FIG. 4 , the output unit 130 of the autonomous vehicle includes a route display module 131 , a benefit display module 132 , and an advertisement display module 133 .

When the input unit initially inputs a destination, the route display module 131 displays a route and a waypoint calculated according to the destination. With respect to the displayed waypoint, the user enters permission or not. At this time, since the waypoint is received from the server 200 due to the continuous change of advertisement data, the waypoint may be changed in real time even for the same destination.

The benefit display module 132 displays the benefits in case of passing through the waypoint. If the stopover is outside the initial route, the arrival time of the destination increases, so the benefit providing module 132 indicates that the vehicle use fare can be reduced or a separate benefit can be paid. These benefits are likewise received from the server 200 .

The advertisement display module 133 loads an advertisement in the process of reaching or driving to the waypoint. In the case of a user who selects a waypoint, since direct exposure of the advertisement is selected, the related advertisement is directly and continuously exposed. In this case, the advertisement display module 133 may augment and output related advertisements according to the location information of vehicles near the stopover in order to maximize the advertisement effect when the waypoint is reached. In other words, in order to protect users who do not want to be exposed to advertisements even after reaching the waypoint, advertisements can be displayed by utilizing the display of the front and rear glass.

Meanwhile, the server 200 includes a stopover database 310 , a fee change module 320 , and an advertisement data management module 330 .

The waypoint database 310 refers to an advertisement database according to each waypoint. In this case, as described above, the waypoints are received from the server 200 due to the continuous change of advertisement data, so that even if the same destination is set, the waypoints may continue to change.

The usage fee change module 320 calculates a change in the fare of the vehicle according to the way of the stopover. That is, referring back to FIG. 1 , it can be seen that the path R2 is longer than the path R1 and the path R3 is longer than the path R2. In addition, in the case of R3, since the waypoints are formed of two (s3, s4), the time required to reach the destination will be further increased. Accordingly, the usage fee change module 320 calculates a change in the fare of the vehicle according to the stopover, and may be reduced in proportion to the number of stopovers or reduced in proportion to the distance at which the stopovers are separated from the original route. Accordingly, when using the R3 route of FIG. 1 and passing through the two stopovers s3 and s4, the width of the fare discount is the largest (or the amount of benefits provided is the largest).

In addition, the usage fee change module 320 can also exempt the fare when changing the stopover itself to the destination. That is, since the user changes their mind after arriving at the stopover and wants to do actual shopping, etc., if they change their destination to the current stopover or purchase related products, the advertisement exposure effect is sufficiently achieved.

The advertisement data management module 330 detects the accumulated amount of propagation of advertisement data. That is, the autonomous vehicle system 1000 according to the present embodiment counts the transmission of advertisement data exposed to one user to another in order to maximize the advertisement effect. That is, the user initially selects a waypoint and while driving to the waypoint, the user can view advertisements, and the fare can be reduced by viewing such advertisements has already been described.

However, further reduction of the fare is possible when such advertisements are more actively spread to other users. Accordingly, the advertisement data management module 330 determines the number of times the user directly transmits the advertisement or metadata included in the advertisement to others after the advertisement is displayed by the display unit 130, and calculates the fare according to the accumulated transmission amount. further reduce

As described above, preferred embodiments of the present invention have been disclosed in the present specification and drawings, and although specific terms are used, these are only used in a general sense to easily explain the technical content of the present invention and to help the understanding of the present invention. , it is not intended to limit the scope of the present invention.
