Description

The inventive device relates to the service equipment of the vehicle, and is intended to inform potential passengers at the stopping point about the number of empty seats in the vehicle, as well as the driver about filling the passenger compartment of the vehicle.

A device for visual display of vehicle information is made in the form of a liquid crystal display located inside the passenger compartment, in the area located between the first and second row of seats, against the wall of the passenger compartment opposite the entrance to the passenger compartment (patent for PM RU43234, September 7, 2007 , on. January 10, 2005). The disadvantage of this device is the lack of provision of information on the number of free places on the information board. In addition, placing the display on the wall opposite the entrance to the vehicle makes the information on it inaccessible to potential passengers at a stop.

The closest analogue adopted for the prototype is a device for indicating the presence of a passenger in the vehicle seat, containing a measuring transducer in the form of a strain gauge installed in the area of each passenger seat, connected to the processing unit and the display (display) unit displayed to the driver. A removable seat cover is introduced into the device, and the strain gauge is made in the form of an elastic flexible plate with strain gages mounted on an elastic flexible plate and placed

between the surface of the seat and a removable cover, (patent RU58087, c. 06.03.2006, on. 10.11.2006). This device involves the supply of information about filling the vehicle only the driver, and does not provide information to potential passengers at the stop. In addition, the type of information presented is not very convenient for perception in driving conditions, since the information is displayed on the display unit from each seat and the number of display units corresponds to the number of seats in the vehicle. The design of the device does not allow automatic calculation of the number of available seats, and the driver’s count of the number of indicator signals showing the availability of empty seats distracts his attention from driving and adversely affects traffic safety. Among the disadvantages of the device, one can also note its complexity, due to the presence of a large number of processing units (installed after each strain gauge sensor), as well as the need to use a special cover on each seat. Also, from the disadvantages of the device, it can be noted that for the actuation of the strain gauge made in the form of an elastic plate, it is necessary to exert some force on this plate, which is impossible in some situations (for example, with bulk but light baggage carried on a vehicle seat). In this way, false information can be generated.

The task to which the claimed utility model is directed is to expand the functionality of the vehicle information system and increase its operational and consumer qualities by simplifying the design, reducing its cost, reducing operating costs, reducing the possibility of false information, and also increasing the information capacity.

To solve this problem, an information warning system about the number of empty seats in the vehicle, including a measuring transducer installed in the area of each passenger seat, the output signal from which is fed to the processing unit, which outputs the processed information to the input of the information display (indication) block to inform the driver, according to a utility model, contains at least one processing unit, made in the form of a controller, and is additionally equipped with an info display unit mation to alert potential passengers, and the transmitter is designed as a non-contact position sensor.

The information display unit for alerting potential passengers is located on a vehicle in the visibility range of potential passengers at stopping points.

The information display unit may be made in the form of an LED display.

The non-contact position sensor is made in the form of a capacitive transducer.

The implementation of the device with one information processing unit allows us to simplify the warning information system, reduce operational and material costs for its installation, commissioning and subsequent maintenance, thereby increasing operational and consumer properties.

The execution of the processing unit in the form of a controller significantly expands the functionality of the system and improves performance.

The implementation of the measuring transducer in the form of a proximity sensor allows you to simplify the system, to eliminate the possibility of false information.

The implementation of the information display unit in the visibility areas of not only the driver, but also potential passengers increases the performance of the device, increases the information capacity.

The device is illustrated in the drawing.

Figure 1 shows a schematic block diagram of the operation of the device.

The information system contains measuring transducers made in the form of capacitive sensors 1, a processing unit made in the form of a controller 2, an information display unit 3 for alerting potential passengers, made, for example, in the form of an LED display mounted on a vehicle in the visibility areas of potential passengers, located at stopping points, and an information display unit 4 for alerting the driver located in his cabin.

Each vehicle seat is equipped with a capacitive sensor 1, which can be placed, preferably, under the passenger seat, on the lower surface of the seat. The sensitivity of the sensor is adjusted to a value lower than the response threshold, so that the seat itself does not cause a false response of the sensor. The operating distance of the sensor 1 is greater than the thickness of the passenger seat. The sensor is triggered when its capacity changes, which occurs, for example, when a person is planted in place. Exceeding the threshold triggers the appearance of a signal that arrives at the controller 2, having the required number of input ports, for receiving and processing signals from all capacitive sensors 1 installed in the vehicle. The controller 2 is preferably located in the driver's cab. After receiving and processing the signal from the sensors 1, the electronic circuit of the controller 2 calculates the number of free places and displays the received information on the LED display 3 mounted on the vehicle. If necessary

the vehicle can be equipped with several displays 3, which are placed on the vehicle in the visibility areas of potential passengers waiting for the vehicle at a stop. The display 4 is located in the driver's cab, preferably in the area of the instrument panel.

The power supply of the information system is carried out, for example, from the vehicle’s battery.

Compared with the prototype of the claimed utility model has the following advantages.

The inventive utility model has a greater informative ability.

The devices used and the relationships between them allow you to expand the functionality of the information system, reduce operating and material costs associated with installation, commissioning and maintenance.

The claimed system is simple and convenient.

Eliminated the possibility of false information about the occupancy of the vehicle seat.
