Abstract
Description
Technical Field
[0001] (Related Application) This application claims priority to U.S. Provisional Patent Application No. 63 / 323,702, filed Mar. 25, 2022, and owned by the same owners, the contents of which are hereby incorporated by reference in their entirety for all purposes.
[0002] (Field of the Invention) The present disclosure relates to systems and methods for automotive theft prevention (vehicle hijacking warning) including distributed visual warning alerts to the surrounding environment of a vehicle, and more particularly to vehicle security devices having primary and display alerts.
Background Art
[0003] Initial conventional vehicle theft prevention systems were installed in vehicles by the owners. Subsequently, theft prevention systems became standard equipment for vehicles by the original equipment manufacturer (OEM). These systems activate an alarm when a sensor is triggered to detect theft. However, some thieves who are proficient in vehicle theft prevention systems may quickly disable the alarm in order to successfully steal the vehicle. A typical vehicle alarm system emits a loud sound and a flashing light through a single actuator that can be easily removed from service. Furthermore, acoustic and optical alarms are very ubiquitous, and their effectiveness as theft prevention has decreased.
[0004] There is a need for a vehicle theft prevention system having a primary alarm system and a secondary alarm system that automatically notifies people near the stolen vehicle that the vehicle is being stolen without the perpetrator noticing the notification.
Summary of the Invention
[0005] According to one embodiment, a system is provided comprising: a theft event sensor; a primary alarm actuator; a display alarm actuator; and a vehicle security device for receiving a theft event signal from the theft event sensor, transmitting a primary alarm signal to the primary alarm actuator, and transmitting a display alarm signal to the display alarm actuator.
[0006] Another embodiment provides a system comprising: a theft event sensor; a vehicle audio alarm actuator; a vehicle display actuator; a vehicle security device that directly or indirectly signals with the vehicle event sensor; the vehicle alarm actuator; and a non-temporary machine-readable medium containing a command, wherein when the command is loaded and executed by the vehicle security device, it commands the vehicle security device to detect a theft event signal from the theft event sensor, transmit a primary alarm signal to the primary audio alarm actuator, and transmit a display alarm signal to the display alarm actuator, thereby instructing a central computer.
[0007] A further embodiment provides a method comprising the steps of: detecting a vehicle theft event; detecting a theft event signal from a theft event sensor; transmitting a primary alarm signal to a primary alarm actuator; activating the primary alarm actuator; and commanding a central computer to display a visual alarm signal on a vehicle's display actuator. The figure illustrates an exemplary method and system for detecting the theft of a vehicle in motion, activating a primary alarm of the vehicle's horn and lights, and activating a display alarm of a “Stolen Vehicle” message around the vehicle. [Brief explanation of the drawing]
[0008] [Figure 1] This diagram shows a schematic of a vehicle theft prevention system in which a central computer communicates with zone-based computers, and the zone-based computers communicate with alarm actuators and theft sensors. [Figure 2] A flowchart of the theft detection algorithm is shown. [Figure 3] A flowchart of the theft detection and alarm display algorithm is shown. [Figure 4] This shows a perspective view of the rear end of the vehicle, where the warning display is located on top of the vehicle itself or projected onto a surface very close to the vehicle. [Figure 5A] This shows a front view of a vehicle with an alarm display located inside the vehicle's grille. [Figure 5B] Figure 5A shows a front view of the vehicle, with the text displayed on the screen spelled out in reverse. [Figure 6] This is a schematic diagram showing a vehicle security device having a control circuit, detection circuit, alarm cancellation circuit, timing circuit, display alarm circuit, and primary alarm circuit. [Figure 7] This is a perspective view of the rear end of the vehicle, showing the warning display located within the head-up display in the rear window. [Figure 8] A flowchart of vehicle theft prevention methods is shown. [Modes for carrying out the invention]
[0009] Reference numbers for any illustrated element appearing in multiple different drawings have the same meaning across the multiple drawings, and any reference or discussion herein of any illustrated element in the context of any particular drawing also applies to each other drawing in which the same illustrated element is shown.
[0010] The vehicle anti-theft system may include any display implementation example that displays a message written in any human language generated by a vehicle LED / OLED matrix, projector, or head-up display, informing the surrounding environment of an ongoing vehicle theft without warning the thief.
[0011] One embodiment adds an additional distributed visual alarm to a vehicle anti-theft system. The system has a primary alarm and a visual alarm, the primary alarm may comprise an audible horn and flashing headlights and road lights. The additional visual alarm may include the display of a legible message. The additional visual alarm may be difficult to disable (as it may be part of a standard car lighting system) and notifies the surrounding environment that a theft is being attempted while the stolen vehicle is in motion, which may help create further awareness of the ongoing crime and may motivate witnesses to act to notify the police or take other measures to thwart the theft. Notifying the surrounding environment of an ongoing theft only while the vehicle is in motion prevents a thief inside the vehicle from realizing that the vehicle is sharing a silent visual alarm signal to the external environment, which can then respond accordingly.
[0012] One embodiment utilizes vehicle infrastructure already planned for use in future vehicles (2025+) and adds new vehicle-to-human (vehicle 2x) communication features (in this context, x represents a human in the vehicle's surrounding environment). It evolves the vehicle's ability to act as a human-machine interface, with each vehicle interacting with other drivers and pedestrians through audio and visual effects while moving on congested roads. Thus, the vehicle itself can also be considered a human-machine interface to increase vehicle safety and security by displaying silent visual warning messages during attempted vehicle theft, without adding cost to the vehicle's bill of materials.
[0013] Figure 1 shows a block diagram of a vehicle zone architecture 100 consisting of a central computer 110 (which may have redundancy) connected to multiple different zone computers 112 via a backbone. The zone computers 112 manage different specific functions within the vehicle and are then connected to dedicated control units 114 that oversee specific functions such as controlling the lights, ensuring vehicle security, or performing other specific tasks. Particularly in this application, when a vehicle user activates the vehicle alarm system, the vehicle security device 116 monitors the vehicle's integrity and oversees vehicle security using different event sensors 118 that detect all attempts at theft, such as unauthorized opening of doors, breaking windows, unauthorized entry into the vehicle, unauthorized attempts to start the engine, or unauthorized attempts to move the vehicle (theft detection). If theft detection is successful, the vehicle security device 116 activates the primary vehicle alarm system (audio alarm actuator 120 and display actuator 122). The activation of the audible alarm is performed via a direct wired connection, as the audible alarm actuator 120 is directly wired to the vehicle security device 116. The activation of the display actuator 122 is triggered via a network event through the central computer 110, which controls all vehicle lights. Furthermore, the vehicle security device 116 also uses network events to notify the central computer 110 of attempted theft (see the algorithm in Figure 2). All logical connections in Figure 1 can be bidirectional, as communication within different zone-type computers 112 can be guaranteed between all zone-type computers 112. Furthermore, the illustrated sensors and actuators may provide diagnostic features that require bidirectional communication.
[0014] Figure 1 shows a schematic diagram of a vehicle anti-theft system in which a central computer communicates with zone-based computers, and these zone-based computers communicate with task-specific electronic control units (ECUs). In one example of a vehicle security device, the front light control unit and the rear light control unit may be connected to different zone-based computers. As a design choice, the ECUs listed above may be connected to a single zone-based computer, or they may represent a different connection topology with available zone-based computers within the vehicle than that shown in Figure 1.
[0015] Referring to Figure 2, one embodiment consists of a system and software algorithm 200 that can control an existing vehicle lighting system based on a digital LED (light-emitting diode) or OLED (organic LED) matrix when vehicle theft is detected, which displays a distributed visual warning in the vehicle's surrounding environment. The algorithm may be integrated into a central computer 110 or a zone-type computer 112 that oversees a vehicle security device 116. This algorithm may also be integrated into a newly manufactured vehicle whose E / E architecture (electrical / electronic architecture) is based on a zone-type architecture. The front light control unit 114 and the rear light control unit 114 may be connected to two separate zone-type computers 112. Alternatively, the front light control unit 114 and the rear light control unit 114 may be connected to the same zone-type computer 112 and physically implemented in the same control unit 114. The vehicle security device 116 may share the zone-type computer 112 with the other control unit 114.
[0016] Another aspect is LED / OLED matrix-based vehicle exterior lighting applications for next-generation automobiles and vehicles. Originally planned for use as exterior lighting, these devices can also display silent alarms, as described above. Signal transmission from the central computer 110 and zone-type computers 112 to the exterior lighting can be implemented using a 10BASE-T1S-based control network, which can be used, for example, to connect a control unit 114 to the corresponding display actuator 122 (LED / OLED matrix). Different nodes within the 10BASE-T1S network can be connected using components such as the LAN867X and LAN865X from Microchip Technology Corporation.
[0017] Referring to Figure 2, the algorithm 200 that controls the silent / visual alarm system can be implemented in the central computer 110, the zoned computer 112, or the control unit 114, as a matter of design choice. In this type of implementation, theft detection is overseen by the vehicle security device 116, but the activation of the silent / visual alarm is performed by the central computer 110 or the zoned computer 112, so the silent / visual alarm system is designed as a distributed alarm system. This is made possible by a network event message that notifies the central computer 110 of an attempted theft. If the vehicle alarm system is active and theft is detected, the central computer (with or without redundancy) or the zoned computer may be (ultimately partially) woken up and notified of the theft event by a network message which may include setting Theft_on-going to 1. Figure 2 illustrates the algorithm 200 that manages the setting of the theft event in the central computer 110 shown in Figure 1.
[0018] Referring to Figure 3, the algorithm 300 that controls the silent / visual alarm system may be implemented in a central computer 110, a zone-type computer 112, or a control unit 114, as a matter of design choice. A flag "theft_on-going" set to 1 from 310 may trigger rear, front, and optional locator lights to display the message "Stolen Vehicle," in which case the message is only displayed if the vehicle is moving and a legitimate user has not disabled the alarm signal. The message "Stolen Vehicle" may be integrated with the message "Call Police," and both messages may flash alternately. The flashing message "Stolen Vehicle / Call Police" may remain active while the vehicle is moving until the flag "theft_ongoing" is reset to 0. The flag "theft_on-going" may be reset to 0 by a password entered via the vehicle human-machine interface or any biometric identification. The password (or hash for biometric identification) may be stored in one of the vehicle's computers using cryptographic hardware or software technology such as Microchip TrustAnchor (TA100). If the value of the flag "theft_on-going" is equal to 1 and any vehicle door is opened by any legitimate vehicle unlocking method, the vehicle's human-machine interface may signal to the user that an attempted theft has occurred and that the distributed vehicle alarm system will display a "stolen vehicle" message, until entering a password / fingerprint via the vehicle's human-machine interface is deactivated. Algorithm 300 may determine whether the car door was opened legally (320). If YES, algorithm 300 displays a request on the human-machine interface to enter a security code to disable the alarm and biometric authentication (330). If a code is entered, algorithm 300 determines whether the user entered a legitimate code (340).If YES, the value of the flag "theft_on-going" is set equal to 1 (350). If NO, the algorithm 300 determines whether the vehicle is moving (whether the wheels are rotating or the GPS position is changing) (360). In step 320, if it is determined that the vehicle door has not been legally opened, the algorithm 300 proceeds directly to step 360. If it is determined in step 360 that the vehicle is in motion (YES), the algorithm 300 displays the message "Stolen Vehicle" or "Call the Police" on the LED matrix (370).
[0019] Figure 4 shows a rear perspective view of the vehicle after the alarm has been triggered. If theft is detected, the rear LED matrix panel can display information, i.e., "Stolen Vehicle", when the vehicle is in motion. Figure 4 shows the stolen vehicle message only at the center where the driver of the vehicle cannot visually recognize the message. This message can blink alternately with the message "Call the Police". In case of theft, the optional locator light on the vehicle side can project the information "Stolen Vehicle" onto the road surface. This message can blink alternately with the message "Call the Police".
[0020] Figure 5A shows a front view of a vehicle having an LED matrix display within the front grill, and an example of the front view of the vehicle after the alarm has been triggered. If theft is detected, the central LED matrix panel at the front of the vehicle shows the information "Stolen Vehicle" when the vehicle is in motion. This message can blink alternately with the message "Call the Police".
[0021] Figure 5B shows a front view of the vehicle of Figure 5A where the text shown on the display is spelled backwards. In this example, the characters "Stolen Vehicle" are displayed backwards, so that when the driver views the display through the rearview mirror, it can be properly read by the driver of the vehicle traveling in front of the displayed vehicle. The message text can blink alternately between forward spelling (Figure 5A) and backward spelling (Figure 5B).
[0022] FIG. 6 shows a schematic diagram showing a vehicle security device 600. The vehicle security device 600 includes a control circuit 602, a detection circuit 618, an alarm解除 circuit 606, a timing circuit 608, a display alarm circuit 610, and a primary alarm circuit 622. The control circuit 602 is coupled to the detection circuit 618, the alarm解除 circuit 606, the timing circuit 608, the display alarm circuit 610, and the primary alarm circuit 622. The control circuit 602 may be coupled to a zone type computer 612 seated on the vehicle backbone. In one aspect, the control circuit 602, the detection circuit 618, the display alarm circuit 610, and the primary alarm circuit 622 may be integrally configured within one housing to form the vehicle security device 600. The control circuit 602 may be, for example, a microcontroller or a microprocessor, but is not limited thereto. In this aspect, the user may install the vehicle security device 600 at any suitable position inside or outside the vehicle. In another aspect, the control circuit 602, the detection circuit 618, the display alarm circuit 610, and the primary alarm circuit 622 of the vehicle security device 600 may be separate components. The alarm解除 circuit 606 may be coupled to the control circuit 602 to enable the alarm to be deactivated or turned off. The alarm解除 circuit 606 may be coupled to an alarm解除 actuator 620 that deactivates the alarm actuator. In this aspect, the user can install separate components at multiple positions inside or outside the vehicle. Alternatively, each component or circuit may be partially integrated and partially separated. >
[0023] It should be noted that the term "警報解除" is translated as "alarm解除" here as there is no exact equivalent in English. You may need to adjust it according to the actual context or specific requirements.As shown in Figure 6, the detection circuit 618 communicates with the theft event sensor 604. In response to the theft event sensor 604, the detection circuit 618 detects at least one event indicating theft of the vehicle, such as an illegally opened door, a broken window, an illegally moved vehicle, or an illegal attempt to start or control the engine. The event sensor may be, but is not limited to, a set of vibration sensors, Hall sensors, pressure sensors, gyroscopes, or Global Positioning Satellite (GPS) devices. Detected theft-indicating events may be, but are not limited to, an illegal move of the vehicle, vehicle motion, vehicle acceleration, door opening, vehicle seat occupancy, or illegal ignition, or an illegal attempt to operate any type of vehicle control, including the vehicle's human-machine interface. For example, when the vehicle moves, the theft event sensor 604 (vibration sensor, gyroscope, or GPS device) may be triggered to output a signal to the detection circuit 618, in which case the detection circuit 618 may determine that an event indicating theft has been detected. Also, when a door is opened illegally, the theft event sensor 604 (vibration sensor and / or Hall sensor) may be triggered to output a signal to the detection circuit 618, in which case the detection circuit 618 may determine that an event indicating theft has been detected. Furthermore, when a person is seated in a vehicle seat, the theft event sensor 604 (vibration sensor and / or pressure sensor) may be triggered to output a signal to the detection circuit 618, in which case the detection circuit 618 may determine that an event indicating theft has been detected. The detection circuit 618 may be integrated into the control circuit 602.
[0024] The control circuit 602 may output an alarm activation signal to the primary alarm circuit 622 and the display alarm circuit 610 in response to a determination that an event indicating theft has been detected. The primary alarm circuit 622 outputs a signal to the primary alarm actuator 614 in response to the alarm activation signal. The primary alarm actuator 614 may activate audible and visual alarms, but is not limited to those known in anti-theft systems. For example, an audible alarm may include sounding the horn or broadcasting a recorded message through a speaker, and a visual alarm may include flashing headlights, road lights, reverse lights, turn signals, or interior lights. The primary alarm may continue until it is deactivated by remote control, or by a key or timer expiring, or by entering a password / fingerprint via the vehicle's human-machine interface through the alarm deactivation circuit 606. The intensity of the primary alarm output by the primary alarm actuator 614 is variable. For example, a warning alarm could be an audible alarm with a different volume, a visual alarm with a different color or brightness, or a seat vibration alarm with a different vibration intensity.
[0025] Furthermore, when the detection circuit 618 detects an event indicating theft, the control circuit 602 sends an alarm activation signal to a display alarm circuit 610, which may be integrated into the control circuit itself. In response to the alarm activation signal, the display alarm circuit 610 notifies the central computer (Figure 1) of the attempted theft via a zone-type computer connected to the control circuit of the vehicle security device 600 through the vehicle's backbone. The central computer processes this notification via the algorithm shown in Figure 2. The central computer considers the event indicating theft to remain active until it is deactivated by entering a password / fingerprint via the car's human-machine interface.
[0026] The alarm deactivation circuit 606 can deactivate the alarm output by the primary alarm circuit 622 by receiving a deactivation signal from the alarm deactivation actuator 620 (e.g., remote control unit or key). Specifically, after the primary alarm circuit 622 outputs each alarm signal, the vehicle owner or any authorized person may determine that the vehicle has not been stolen and resolve the theft-indicating event by deactivating the primary alarm system, for example, via the remote control unit or key. At this point, the user can enter the vehicle without the primary alarm system being deactivated. After the user occupies the driver's seat, the vehicle's HMI (Human-Machine Interface) prompts the user to verify themselves by entering a passcode / fingerprint / facial recognition / voice recognition / retinal recognition, or by using any other available biometric authentication. If the user can reliably identify themselves, the central computer deactivates the visual distributed alarm system by resetting the flag "theft_on-going" (Figure 3). This two-step authentication increases the vehicle's security, as unauthorized users could bypass the first authentication step and access the vehicle without deactivating the primary alarm.
[0027] The vehicle security device 600 may also have a timing circuit 608 for timestamping events and alarm activation signals indicating theft. Authorized persons may retrieve the timestamps.
[0028] Each of the circuits shown in Figure 6 can be implemented, whether in a single device or distributed across several devices, by a processor, function, library call, subroutine, shared library, software as a service, analog circuit, digital circuit, control logic, digital logic circuit programmed through a hardware description language, application-specific integrated circuit (ASIC), field-programmable gate array (FPGA), programmable logic device (PLD), or any preferred combination thereof, or by instructions in a storage medium for execution by any other preferred mechanism.
[0029] Figure 7 shows a head-up display in a rearview window that displays a message around the outside of the vehicle but not to the vehicle's occupants. The head-up display in the rearview window (or any other window) may include an organic light-emitting diode (OLED) screen positioned in contact with the window. The OLED screen may include a screen portion used to display "Stolen Vehicle" or "Call Police." A transparent screen may allow the vehicle's occupants to view the message through the window without seeing it, while people outside the vehicle can see the message. Alternatively, a rearview camera view of the vehicle may be presented inside the display to prevent the vehicle's occupants from seeing the "Stolen Vehicle" or "Call Police" message projected for people outside the vehicle to see. The vehicle's rear window may be a substantially transparent window head-up display with light-emitting particles or microstructures on the glass, enabling luminous display while allowing vision through the window. The head-up display message may be projected onto the rear windshield.
[0030] The window may take the form of an insulating glass unit having an electrochromic device, a transparent display, and a controller for controlling the optical state of the electrochromic device and the transparent display. The controller may adjust the transparent display between a substantially transparent optical state and a substantially opaque optical state. The display may be pixelated to allow text or graphic messages to be displayed. The transparent display may be an organic light-emitting diode (OLED) display. The OLED display may display messages to the external environment.
[0031] A transparent display may be an electrowetting display having multiple pixels, each pixel having at least one cell that can vibrate between a transparent state and an opaque state. The cell may vibrate at a frequency of about 30 Hz to about 60 Hz. A pixel may have a cell that can be substantially white (or substantially black) in the opaque state. If the pixels of the electrowetting display can be changed to white (or other bright color), the window may include a projector that projects an image onto the electrowetting display. Some of the pixels of the electrowetting display may consist of multiple cells that provide different colors from each other in the opaque state.
[0032] A transparent display within a vehicle window may be a passive coating that is substantially transparent to the observer but reflects projected light to form an image. The window may include a projector that projects an image onto the transparent display. The projector may, in some cases, be located on or within a frame configured to hold the window, or the window may include a light guide that directs the image from the projector to the transparent display.
[0033] The rear windshield head-up display may be transparent to the occupants inside the vehicle while displaying messages on the outside of the window to the surroundings. Alternatively, the rear windshield head-up display may be opaque to the occupants inside the vehicle while displaying messages on the outside of the window to the surroundings. In either case, the messages displayed on the outside of the window to the surroundings may or may not be readable by the occupants inside the vehicle. The head-up display may be fully integrated into the rear windshield.
[0034] Figure 8 shows a flowchart of a method for providing visual notification to an individual outside the vehicle that a vehicle theft is in progress. The method detects whether a theft event has occurred (801). If a theft event is detected, the method detects a theft event signal from the theft event sensor (802). The method then transmits a primary alarm signal to the primary alarm actuator (803). The primary alarm actuator is then activated (804). The method then transmits a display alarm signal to the display alarm actuator (805). The display alarm actuator is then activated (806).
[0035] Vehicle security devices are connected to the vehicle's backbone network and have the potential to communicate with other network nodes.
[0036] While examples have been described above, other variations and examples can be derived from this disclosure without departing from the spirit and scope of these disclosed examples.
