Description

Recommended indication device

speed range

The utility model relates to systems for regulating the movement of vehicles, namely road vehicles, in particular to indicators of the recommended vehicle speed with a map display installed inside the vehicle, and can be used to control the movement of vehicles in the intersection of regulated intersections.

A known traffic control system using active road signs and subscriber devices of vehicles (see patent for utility model RU 97841, IPC G08G 1/09). The system comprises an information processing center, an information display device, a central control station, a group of territorial control stations located on city highways and highways, structurally connected to traffic lights or traffic monitoring points and equipped with vehicle flow sensors, groups of controlled traffic signs, each of which is capable of changing the image displayed on it and generating a warning radio signal for vehicles located close to it, as well as subscriber control information display devices arranged on vehicles, configured to receive vehicle control information from controlled traffic signs and its display in graphic, text and sound forms. Signals from the territorial control stations are sent to the information processing center, where all incoming information is processed and a single picture of traffic flows over the entire observation area is formed. The processed information arrives at the central control station, in which control signals are generated, for example, vehicle speed limit signals in individual sections, speed limit reset signals, etc. These signals are transmitted to territorial control stations, which transmit them to the corresponding groups of controlled road signs. Such road signs can be made in the form of flat monitors with LEDs, or in the form of mechanically interchangeable panels with the corresponding images, allowing the control signal to change the color image presented on them, for example, to change the numbers characterizing the speed limit. The control command from the controlled traffic signs is received at the input of the vehicle receiving device, from where information is extracted from the standard command memory and fed through the video controller to the screen, and through the audio controller to the loudspeaker.

A disadvantage of the known system is the complexity due to the presence of elements such as an information processing center, a central control station, a group of territorial control stations, vehicle flow sensors, controlled traffic signs. Moreover, with such complexity, the system does not allow vehicles to hit the green traffic light.

A known system for automatically controlling the speed of a car (see patent for utility model RU 43989, IPC G08G 1/09, G05D 13/00). Along the highway there are speed limit indicators and three-color traffic lights. Each of the indicators has a frequency generator corresponding to a given speed value, and each of the traffic lights has an adjustable frequency generator, the value of which corresponds to the speed limits determined by the yellow and red colors of the radiation. At the signs and traffic lights stationary antenna systems are provided. The vehicle has a unit for measuring the current speed, an automobile antenna system, a receiving device, a system of filter shapers tuned to the frequencies of speed limit indicators and traffic lights, and a set of comparison units started by filter shapers to compare the current and specified speed and traffic lights. At the output of one or another comparison unit, a signal is generated corresponding to the difference between the current and predetermined speeds, which is amplified and fed to an actuator made, for example, in the form of a solenoid interacting with a damper in the fuel supply channel. The system works as follows. To each value restrictions on the speed of the car, given on the signs, is set in accordance with its own frequency of radiation. On the track, at each speed limit indicator, the frequency generator generates a signal frequency corresponding to a given limit value, the radiation of which, after amplification, is carried out by the antenna system. At each traffic light, respectively, red and yellow, signals of the frequencies selected for yellow and red are formed. The signals are emitted by an additional stationary antenna system, and are received by the antenna system installed on the vehicle. In the activated comparison unit, the current speed value and the threshold value are compared. The signal corresponding to the difference between the current and the set speeds is supplied to the actuator, which can be performed, for example, in the form of a solenoid that interacts with a valve in the fuel supply channel or acts on the brake system to reduce the speed of the car. The disadvantages of the known system is the complexity, as well as reducing the need for safety intervention in the management of the vehicle in the absence of control systems and duplication systems. In addition, the system does not allow vehicles to hit the green traffic light.

Closest to the claimed is a device for indicating the recommended speed (see patent for utility model RU 108874, IPC G08G 1/052). At the beginning of a road section (lane), limited on one (at the end in the direction of travel), or on two sides intersections regulated by traffic lights, a transmission device is installed for transmitting information about the speed interval, following which the driver of the vehicle will reach the end of the lane at the period of time corresponding to the permission signal of the traffic light - green light. Information about the speed interval is pre-calculated using data on the length of the haul and the time intervals between the enable and disable traffic signals, installed at the end of the haul. The vehicle is equipped with a device for indicating the recommended driving speed, comprising a receiving device designed to receive information from a transmitting device installed at the beginning of the haul at the moment of driving past it, and then making a correction coefficient depending on the speed of the vehicle at the time of receiving the signal. To reduce interference from transmitting devices from neighboring intersections, the transmitting and receiving devices are equipped with narrowly oriented antennas. The device for indicating the recommended speed of movement also contains an indicator connected to the receiving device and intended for the visual presentation of information to the driver of the vehicle. The indicator is a sequence of LEDs (or other light-emitting elements), each of which corresponds to a certain value of the vehicle speed. The indicator can be made in the form of an arc of a circle and is located around the speedometer, or along the upper edge of the instrument panel. A disadvantage of the known system is the error in the calculation of the intervals of the speed mode. This error, despite the correction factor, arises due to the fact that each driver selects individual (both positive and negative) acceleration for their vehicle (vehicle) on the stage between traffic lights to achieve the optimal speed mode, and vehicle acceleration can arise in connection with various circumstances associated with the road situation. Such a system cannot be used on public transport and on cars moving with stops on the stages.

The objective of the utility model is to increase the throughput of roads and, as a result, reduce fuel consumption and the emission of air polluting substances by all vehicles, including public and vehicles with acceleration on the stretches between traffic lights.

The technical result is to reduce the error in calculating the recommended interval of vehicle speed. The specified technical result is achieved in that the device for indicating the recommended range of speed, containing the receiving device and an indicator connected to the receiving device mounted on the vehicle, according to the decision, the receiving device is configured to receive information about the time until the next turn on That and duration Ts permission signal of a traffic light located on the route of the vehicle, as well as information about the coordinates of the position of the vehicle, d moving at a speed of V, and the indicator is a monitor configured to display a map of the area plotted on the road on which the vehicle is located, a segment whose beginning indicates the current position of a point remote from the traffic light at a distance Smin = Vmin * To, and the end the segment denotes the current position of the point located at a distance Smax = Vmax * (To + Ts), where Vmirr ^ Vmax is the recommended speed interval. The utility model is illustrated by drawings, where in FIG. 1 shows a vehicle equipped with the inventive device on the stretch between traffic lights at the time of the first signal, FIG. 2 presents an example of displaying the recommended interval of speed on the screen of the claimed device. The positions in the drawings indicate:

1 - traffic light;

2 - transmitting device;

3 - receiving device;

4 - vehicle;

5 - stage;

6 — satellite;

7 - segment of low speed;

8 - segment of average speed;

9 - segment of high speed;

10 - a generalizing segment;

11 - speed indicators;

12 - transmitting GLONASS / GPS device.

On public roads in the conditions of traffic light control, very often a situation occurs in which a car with a larger at a prohibiting signal of a traffic light and forcibly stops, and the car approaches the adjustable intersection with green at a slower speed and is in front. The first car suffered aerodynamic losses, spent energy on maintaining greater speed, braking, acceleration, the engine worked part time at idle, which negatively affected environmental pollution, and as a result was behind the second, which spent less fuel and less time on passing the intersection. In another situation, sometimes even slightly increasing the speed (within the permissible traffic rules Vmax), the car manages to allow the traffic light and thereby again saves time, energy on braking, acceleration and less harmful to the environment, reducing the engine idling time. The throughput of roads increases, as the transit time of the intersections of each car separately decreases. It is impossible to fight with the claimed device with an existing traffic jam, but due to an increase in throughput the ability of roads and intersections, the time of occurrence and existence of traffic jams is significantly reduced. The need to know the optimal vehicle speed is obvious.

The inventive utility model includes a receiving device 3, intended for installation on a vehicle 4 to enable reception of a signal from a transmitting device 2 containing information about the time until the next turn-on and duration Ts of the enable signal of the traffic light 1 located on the route of the vehicle. The receiving device 3 is configured to receive information about the coordinates of the position of the vehicle 4 from satellite 6 GLONASS or GPS. The inventive device contains an indicator mounted on the vehicle and connected to the receiving device 3. The indicator is a monitor made with the possibility of displaying a map of the terrain and symbolic position on the terrain of the vehicle (analogue of the GPS navigator with a memory unit and computing device, see FIG. 2). The indicator is configured to plot in real time section 10 or segments 7, 8 and 9 on the image of the road on which the vehicle 4 is moving. The device’s memory contains information on the recommended speed interval Vmin Vmax established on the basis of traffic safety rules: for example, in urban traffic conditions Upp = 20km / h, Utah = 70km / h. Since the speed capabilities of cars, as well as the conditions on the road are different, the device can be adjusted by the driver of these speeds.

The device operates as follows. Information about the switching time of the traffic light 1 That and Ts is transmitted through the transmitting device 2 to the receiving device 3 located on the vehicle 4. The generalizing segment 10 is displayed as follows: the beginning of the segment indicates the current position of the point located at a distance from the traffic light Smin = Vmin * To, and the end of the segment denotes the current position of the point removed by the distance Smax = Vmax * (To + Ts). The beginning and end of the segment are equipped with appropriate speed indicators 11. With the course At the same time, data on To and Ts changes, therefore, the indicator displays updated information. As a result, a virtual segment moving along the roads can be displayed on the navigator’s screen, combining cars with different speeds, but shortening as it approaches an adjustable intersection. In FIG. 2, the driver of the vehicle 4, indicated by an arrow, must accelerate to get into section 10 and have time to cross the intersection at the traffic light permitting signal.

Figure 2 shows the moving moving on the stretch 5 segments virtually combining machines with different speeds. 7 - with less (for example, 40km / h), 8 - average (for example, 50km / h), and 9 - with higher speed (for example, bOkm / h). The beginning of each segment is located at a distance Smin = V * To from the traffic light, and the end is at a distance Smax = V * (To + Ts), where V is the speed of the cars in the corresponding segment. The shorter the segment, the lower the speed of the machines that it combines. Longer segments move faster, but by the beginning of the intersection opening (turning on the green traffic light 1), all the beginning of the segments coincide by at the traffic light intersection, and at the intersection closure, the ends of the segments coincide. Thus, any car located in these segments and not exceeding the limits of the beginning of the first and the end of the last segment, surely gets to the resolving signal of the traffic light. Speed intervals can be distinguished on the navigator’s roads as moving segments highlighted in color, beacons (at the beginning and end of the segment) with speed indicators, or both. The segment will imply the presence of machines at the same speed. In FIG. 2, the driver of the vehicle 4, indicated by the arrow, must slow down in order to pass the intersection at the green signal of the traffic light 1 in one of the segments 7 - 9.

When installing the transmitting device 12 (Figure 2), directly at the traffic light object 1, the signal of the switching time of the light signal is transmitted to the GLONASS / GPS satellite system. There is no need for devices 2 and 3 (Figure 1). The optimal speed of the passage between the traffic lights is calculated in the calculator unit of the navigator according to the formula V = S / T, after the corresponding software firmware processor, and displayed on the in-memory graphic maps of the area, as shown in (Figure 2).
