Description

The utility model relates to the field of mechatronic and automated systems, mainly to on-board systems of vehicles.

A device is known - automatic car parking system Pat. 6170591 U.S. IPC ⁷ B60S 9/00. Honda Giken Kogyo KK, Sakai Katsuhiro, Shimizu Yasuo. N 08/992339; Claim 12/17/1997; Publ. 01/09/2001; Prior. 12/17/1996, N 8-336958 (Japan); NPK 180/204. English .. US. Patented electronic system for automatic parking of a car provides automatic control of its movement along the path of arrival forward or backward with turns to the left, right or straight. A radar, ultrasound or television system provides the detection of obstacles on the trajectory with their display on the instrument panel display and the supply of a voice signal. When the driver cancels the parking command, the car will automatically return to the starting point, after which it is possible to repeat the parking command on a new path taking into account the detected obstacles.

The disadvantages of this system are the inability to enter the vehicle into the parking lot or exit from it by lateral movement in conditions of insufficient space for maneuver; it takes a lot of time to work with the equipment when setting the vehicle trajectory and controlling the parking process as a whole, and when the driver cancels the parking command, the car automatically returns to the starting point, which is unacceptable in modern traffic conditions.

In addition, it is difficult or impossible to equip vehicles with earlier production periods or vehicles, the basic equipment of which did not provide for such systems initially, with this device.

A device for lateral movement of vehicles [WO 2004000617], adopted as a prototype, containing four separate nodes of the lateral movement (block lateral movement), allowing the vehicle to move to the side. Each node includes a roller (track roller) with a motor on a horizontal shaft, a roller console (track roller) with a motor for lowering and raising the rollers (track rollers) and an engine for turning the roller (track roller) around its vertical axis. Rollers (track rollers) are lowered, raised, rotated and driven by hydraulic, pneumatic or electric motors, presented in the design of each unit in the amount of three units (pieces).

The nodes are made of two types - they are similar in structure, but have a mirror arrangement in design. All nodes are connected through a control panel (system control panel) located in the cab or outside the vehicle.

The design of this device has the following disadvantages: 1) the presence of three engines in each node leads to a complication of the design, an increase in mass and overall dimensions, an increase in the cost of the device, and a deterioration in the aerodynamic properties of the vehicle as a whole; 2) the use of a direct drive of the support rollers from the engines makes it necessary to use engines of greater power, which also leads to an increase in mass and overall dimensions, an increase in the cost of the device, and a deterioration in the aerodynamic properties of the vehicle as a whole. A disadvantage of the device is the need to use two types of nodes in the system. During operation of the system, the design of the nodes does not have spatial rigidity, which leads to the lack of stability of the entire vehicle when using this device as part of the system, which, in the case of an inclined base or a displaced center of gravity, can lead to deformation of structural elements or to capsize the entire vehicle, and is not safe. Unsafe in the design of the device nodes is the absence of blocking elements that prevent the arbitrary rotation of the track rollers, which does not exclude uncontrolled movement of the vehicle at the time of operation of the system. The operation of devices in the system is not automated - the driver is forced to control: the amount of available space for maneuver, the spatial positioning of the vehicle, the position and interaction of all nodes in the system.

The inventive utility model is aimed at solving the problem of automated parking of vehicles, allowing for safe parking of the vehicle by lateral movement in a space slightly exceeding its overall length, where parking is possible only by lateral movement, as well as to ensure exit from the parking space.

The technical result of the implementation of the utility model is to increase the safety of parking a vehicle in a space slightly exceeding its overall length, where parking is possible only by lateral movement of the vehicle, automating the parking process, reducing the weight and size characteristics of lateral displacement units (lateral displacement units), and reducing the cost of manufacturing the system , as well as expanding the functionality of the system. In addition, the proposed utility model provides ease of use and flexibility in managing the parking process, reducing the accident rate of the parking process and significantly reducing the time required to maneuver.

The specified technical result is achieved using a vehicle automated parking system containing a control panel of at least four lateral movement units, in addition, the system includes a control and preparation unit, at least two distance measuring sensors and at least four a positioning sensor connected to the control panel, and each of the lateral displacement units integrated into the lateral displacement module, through the control and preparation unit, is connected to the control panel and, moreover, the control panel, control and preparation unit, distance measuring sensors and positioning sensors are integrated into the control and management module.

From the existing level of technology has not been identified a set of essential features of the proposed system, which indicates the compliance of the utility model with the criterion of "novelty."

Distinctive features of the automated parking system is the presence of a control and management module, simplification of the design of the blocks of the lateral movement module.

The essence of the utility model is illustrated by drawings, where in Fig.1 - shows a structural diagram of an automated parking system; figure 2 - shows a General view of the block lateral movement (BBP) with the active system; figure 3 - shows a diagram of the parking lateral movement, explaining the implementation of the proposed method.

Figure 1 shows the structural diagram of the system proposed for patenting, which consists of a control and management module (MCU) 1 and a lateral movement module (MBP) 2. The control and management module (MCU) 1 consists of a system control panel (CCP) 3, the control and preparation unit (BUP) 4 of at least two distance measuring sensors 5.1 and 5.2, activated, respectively, in the right-hand and left-hand direction of parking, and at least two positioning sensors 6.1 and 6.2, activated, respectively, when right-wing officer nnem parking and left-hand direction. The system control panel (CCP) 3 is connected to a distance measurement sensor 5.1, activated in the right-hand parking direction and distance measurement sensor 5.2, activated in the left-hand parking direction, at least two position sensors 6.1, activated in the right-hand parking direction and at least , by two position sensors 6.2, activated in the left-hand direction of the parking. The lateral displacement module (MBP) 2 includes at least four identical in structure, construction and execution, lateral displacement block (BBP) 7 (Fig. 2). The control and management module (MCU) 1 is connected to the lateral movement module (MBP) 2 by connecting the system control panel (CCP) 3 through the control and preparation unit (CUP) 4 to each side movement unit (CBC) 7. Moreover, the control panel (CCP) ) 3 is configured to receive information from distance measurement sensors 5.1 and 5.2 and positioning sensors 6.1 and 6.2, create a control action on the control and preparation unit (BUP) 4, store, analyze, monitor, adjust and adapt the optional information to by direct action, and the control system automatically, exchanging information with the driver, and also provides an intuitive interface for system control of the driver. Each lateral displacement block (BBP) 7 contains a base 8 on which at least two interlocked power cylinders 9 with rods 10 are fixed. The rods 11 of the positional cylinders 12 are attached to the power cylinders 9, and a gearbox 13 is attached to the rods 10 of the power cylinders 9 , which contains a worm gear consisting of a pinion shaft (not shown in the figure) and a worm (not shown in the figure). The motor 14 mounted on the gearbox 13, in conjunction with it, constitute the drive of the track rollers 15, fixed at the output ends of the pinion shaft (not shown in the figure).

Consider the operation of a vehicle automated parking system.

A system consisting of a control and management module (MCU) 1 and a lateral movement module (MBP) 2 is mounted on board a vehicle. Blocks lateral movement (BBP) 7 through the base 8 are attached to the supporting elements of the vehicle body. The system control panel (CCP) 3 is located at the driver, and the control and training unit (CUP) 4 is installed inside the vehicle body, for example, in the hood. Distance sensors 5.1 and 5.2 are mounted in the vehicle body, for example, in the bumper. Positioning sensors 6.1 and 6.2 are placed, for example, as part of lateral displacement units.

If there is a need for parking, the driver activates the system by turning on the system control panel (CCP) 3 and selects the appropriate entry "Parking entry", tells the system about his desire to park the vehicle in the desired direction. The system activates a distance measuring sensor 5.1 or 5.2, depending on the selected parking direction (right-hand or left-hand) and searches for sufficient space for maneuver in the corresponding row of obstacles. The dimensions of the controlled vehicle are entered into the memory of the system control panel (CCP) 3, therefore, after calculating the space required for parking, the system reports this and offers the driver to bring the vehicle to the parking position (Fig. 3). If the driver refuses to park in the proposed location, the system offers “Shut down the system” or “Search for a new location”. If the driver agrees to park at the proposed location, the system, using the distance sensor 5.1 or 5.2, depending on the chosen direction of parking (right or left), helps the driver to stop the vehicle at the parking position, which is optimal for maneuvering. When the vehicle reaches the parking position, the system asks the driver for parking confirmation at the selected location. In the event of a driver’s refusal to park in the proposed location, the system offers to “Search for a new location” or “Shut down the system.” If the driver confirms the decision to continue the maneuver, the system activates the control and preparation unit (BCU) 4 and the corresponding positioning sensors 6.1 or 6.2, depending on the chosen parking direction (right-hand or left-hand). The control and preparation unit (BUP) 4, in turn, provides synchronous operation of the lateral movement blocks (BBP) 7 of the lateral movement module (MBP) 2. Each of the lateral movement blocks (BBP) 7 operates in the following sequence: into positional cylinders 12 of control and preparation unit (BUP) 4 is supplied with a working medium (gaseous or hydraulic), under the action of which the positional cylinders 12 through the rods 11 output power cylinders 9 with a gear 13 mounted on their rods 10, an engine 14 and track rollers 15 into the working dix. After this, the working medium is supplied to the power cylinders 9. Under its action on the rods 10 of the power cylinders 9, the track rollers 15 are lowered onto the surface of the road surface, and as a reverse reaction, the vehicle is lifted until the wheels of the vehicle are completely detached. from the surface of the road surface. The control and preparation unit (BCU) 4 activates the motor 14, which transmits torque to the worm (not shown in the figure) by the rotating output end of the shaft, which, in turn, reports rotational movement to the pinion shaft (not shown in the figure), and that - track rollers 15. The system drives the vehicle, and by lateral movement carries out its parking in a given space (figure 3). The system controls the lateral movement and stops it by turning off the drive roller drive motor 14 of the track rollers 15 as soon as a signal is received from the appropriate positioning sensors 6.1 or 6.2 that an acceptable distance to the obstacle has been reached (for example, a curb, wall, etc.). Also, for safety reasons (for example, an unexpected occurrence of an obstacle - a person, animal, other objects), the driver can interrupt lateral movement by reporting the appropriate command to the system via the control panel (CCP) 3. Upon completion of the lateral movement maneuver, the system informs the driver about it and issues a request for further actions, for example:

- “Shutdown” - in this case, the system, due to the reverse action of the power cylinders 9, lowers the vehicle with the wheels onto the surface of the road surface, by the reverse action of the position cylinder 12 transfers and fixes the power cylinders 9, with a gearbox 13 mounted on their rods 10, the engine 14 and the track rollers 15, in their original (transport) position and stops its work.

- "Departure from the parking space." If there is a need to leave the parking lot, the driver must make the choice of the required direction of maneuver. The system, through the control and preparation unit (ECU) 4, includes the reverse operation of the engine 14 of the lateral displacement units (LPS) 7 of the lateral displacement module (MBP) 2 and with the lateral displacement displays the vehicle on the parking position. The system controls the lateral movement and stops it by turning off the drive motor 14 of the track rollers 15 as soon as the parking position is reached. Also, for safety reasons (for example, an unexpected occurrence of an obstacle - a person, animal, other objects), the driver can interrupt lateral movement by informing the appropriate command through the control panel (CCP) 3 of the system. Upon completion of the lateral movement maneuver, the system informs the driver about it and issues a request for further actions, for example:

- “Shutdown” - in this case, the system, due to the reverse action of the power cylinders 9, lowers the vehicle with the main wheels to the surface of the road surface, by the reverse action of the position cylinder 12 transfers and fixes the power cylinders 9, with a gearbox 13 mounted on their rods 10 , the engine 14 and the track rollers 15, in their original (transport) position and stops its work.

- “Search for a parking space” - in this case, the system activates a distance measuring sensor 5.1 or 5.2, depending on the chosen parking direction (right-hand or left-hand) and searches for enough space for maneuver in the corresponding series of obstacles. The dimensions of the controlled vehicle are entered into the memory of the system control panel (CCP) 3, therefore, after calculating the space required for parking, the system reports this and offers the driver to bring the vehicle to the parking position (Fig. 3). In the event of a driver’s refusal to park in the proposed location, the system suggests terminating its work or continuing to search for a parking space. Further work of the system occurs in accordance with the algorithm described in the description of the option "Entrance to the parking lot."

Among other things, the system has the “Lift” option, which acts as a jack or a professional lifting device when replacing wheels, inspecting or repairing a vehicle. Having received a command from the driver to lift the vehicle, the system activates the control and preparation unit (ECU) 4, which, in turn, provides synchronous operation of the lateral displacement units (BBP) 7 of the lateral displacement module (MBP) 2. Each of the lateral displacement blocks (BBP) 7 operates in the following sequence: a working medium (gaseous or hydraulic) is supplied to the positioning cylinders 12 from the control and preparation unit (BCU) 4, under the action of which the positioning cylinders 12 output force through the rods 11 high cylinders 9 with a reducer 13 mounted on their rods 10, an engine 14, and track rollers 15 to a working position. After this, the working medium is supplied to the power cylinders 9. Under its action on the rods 10 of the power cylinders 9, the track rollers 15 are lowered onto the surface of the road surface, and as a reverse reaction, the vehicle is lifted until the wheels of the vehicle are completely detached. from the surface of the road surface. Upon completion of work as a lifting device, the system, due to the reverse action of the power cylinders 9, lowers the vehicle with the wheels onto the surface of the road surface, by the reverse action of the position cylinders 12 translates and fixes the power cylinders 9, with a gearbox 13 mounted on their rods 10, an engine 14 and track rollers 15, in their original (transport) position and stops its work.

Thus, the proposed parking system provides:

- improving the overall dimensions of the lateral displacement module of the system without loss of power and torque due to the use of a drive consisting of a smaller motor in combination with a gearbox;

- unification of lateral displacement blocks and, as a result, reduction of their prime cost due to the use of the same structure, design and components;

- the safety of using the automated parking system by creating the spatial stability of the entire vehicle: in the transverse direction - due to the location of positional cylinders in the construction of lateral movement blocks; in the longitudinal direction - due to the use of two interlocked power cylinders in the design of lateral movement blocks, as well as the operation of the system on inclined surfaces (for example: preventing reverse or uncontrolled rolling of the vehicle), due to the use of a worm gear reducer in the lateral movement of the block structure, structurally providing self-locking of transmission elements from the reverse action of track rollers experiencing the influence of gravity of the entire transport medium tilt;

- simplicity of operation and control flexibility, reducing the accident rate of the parking process and a significant reduction in the time required for maneuvering due to the intuitive organization of the interface of the control panel of the system, the automation of the system and its main options (functions).
