Abstract

An informative system applicable to vehicles includes a sensing unit, a control unit, and an alarming device. The sensing unit senses if there is any vibration or interference occurred on a parking vehicle, and the result is shown by a sensing signal. A number of thresholds are compared with the sensing signal to see if the signal meets one of the default events. If the sensing signal shows that an event that calls for the driver's attention has occurred, the sensing issues a trigger single. The control unit receives the trigger signal and generates an event log accordingly. The control unit further collects information relevant to the event log. The alarming device is connected to the control unit and provides an alarm to inform the driver the event.

Description

Warning system and warning method

The present invention relates to a warning system and a warning method, and more particularly to a warning system and a warning method with a vibration or disturbance warning function.

Conventional vehicle sirens issue a warning sound to alert the owner or driver when the vehicle is touched when the vehicle is not started. However, when the driver is in a place where the audible alarm cannot be heard, these conditions cannot be known. For example, when the driver is away from the car and is in a place where he cannot hear or receive the alarm, even if the driver returns to the parking place, it is impossible to know whether the car has an accident while the driver is away. In other words, the traditional vehicle alarm only has the function of issuing a warning within a limited range at the moment of the event; however, when the driver is far away and cannot receive the alarm, the driver cannot know the event, and even if he returns It was not immediately possible to detect the accident when you were near the vehicle. As a result, the limitations of conventional vehicle alarms cause drivers to miss the best time to deal with an accident.

The invention provides a warning system and a warning method, which are used to remind a driver whether the vehicle has ever caused vibration or disturbance due to contact or collision while leaving the vehicle.

The automobile warning system of the present invention includes: a sensing unit, which senses the vibration or disturbance of a vehicle when a vehicle is stationary, and the sensing result is represented by a sensing signal; wherein the sensing signal is compared with a plurality of preset values for Determine whether a preset event is met. If the preset event needs to be notified to the driver of the vehicle, the sensing unit generates a trigger signal; a control unit is electrically connected to the sensing unit, the control unit receives the trigger signal and generates a The event records and collects an event data related to the event records; and a warning device connected to the control unit, wherein the warning device prompts the driver to the event.

The automobile warning method of the present invention comprises: sensing vibration or disturbance of a vehicle and obtaining a sensing signal; judging whether the sensing signal conforms to a preset event according to at least one preset value; and if so, issuing a trigger signal; corresponding to the trigger signal Generate an event record; collect event data related to the event record; and remind the driver of the occurrence of the preset event.

Compared with the prior art, the warning system of the present invention can remind the driver to let the driver know whether the vehicle was shaken or disturbed during the departure, and understand the accident situation from the related event data including captured images, so that the driver One can immediately respond to the accident. In addition, the driver can also receive notifications through the mobile device, so that the vehicle can be informed in real time that the vehicle has been shaken or disturbed.

FIG. 1 is a schematic diagram of a warning system 100 according to an embodiment of the present invention. As shown in the figure, the warning system 100 of the present invention can be used for a vehicle 300 to inform the driver whether the vehicle 300 has ever experienced a vibration or disturbance event during the time of its departure.

The warning system 100 includes a storage unit 140, a sensing unit 160, a control unit 180, and a warning device 190. When the vehicle 300 stops, the sensing unit 160 starts to sense vibration or disturbance of the vehicle 300. FIG. 1 exemplarily sets the sensing unit 160 at a position of a right door of the vehicle 300, but this does not mean that the sensing unit 160 can only sense vibration or disturbance received by the right side of the vehicle 300. The sensing unit 160 of the present invention can also sense vibrations or disturbances on the front and rear bumpers of the vehicle 300, left and right doors, and any possible position of the vehicle body. In addition, the sensing unit 160 can also be placed at any position of the vehicle 300, or it can sense vibration or disturbance at other specific locations on the vehicle 300 according to design requirements.

The sensing unit 160 of the present invention can be set with different sensing sensitivities. For example, when the vehicle 300 is located in an area with more sand and gravel, the driver may set the sensing unit 160 to have a lower sensing sensitivity to avoid misjudgement of a general touch of sand and gravel as an impact event. In another embodiment, the warning system 100 may also store a plurality of sensing signal waveform diagrams or condition judgment values in advance, which respectively correspond to a preset event for filtering unrelated events that do not need to prompt the driver. For example, when the amplitude of the signal detected by the sensing unit 160 is lower than a preset value, the warning system 100 may determine that the vibration or disturbance of the vehicle 300 may be caused by a gravel collision or a human hand touch, so No need to issue a reminder to the driver. Furthermore, if the amplitude of the signal detected by the sensing unit 160 is greater than a preset value, but the number of consecutive large vibrations exceeds another preset value, the warning system 100 may determine that the vibration or disturbance of the vehicle 300 may be As a result of prolonged strong wind or rain, there is also no need to issue a reminder to the driver. In addition, when the vehicle 300 is stationary, if the vehicle 300 is suddenly hit by another vehicle, the signal waveform diagram that the sensing unit 160 may sense is as shown in FIG. 2.

As shown in FIG. 2, when the Te sensing unit 160 detects that the vibration of the signal is greater than M at a certain point in time, the sensing unit 160 starts to continuously detect the signal within ΔT time. If the maximum amplitude of the signal during the period exceeds a first preset value A and the gap between two adjacent peaks exceeds a second preset value B, the warning system determines that the event of the vibration or disturbance is an event that needs to be prompted to the driver Therefore, the sensing unit 160 sends a corresponding trigger signal.

The warning system 100 of the present invention may include other signal waveform diagrams that need to prompt a driver event or preset values corresponding to different preset events, and the second figure is only one embodiment of the present invention.

The control unit 180 is electrically connected to the storage unit 140, the sensing unit 160, and the warning device 190. When the sensing unit 160 senses a vibration or disturbance event that needs to prompt the driver, a trigger signal is generated and sent to the control unit 180. In response to the received trigger signal, the control unit 180 generates an event record and stores event data related to the event record in the storage unit 140. The warning device 190 will then prompt the driver about this event. The method of prompting the driver includes broadcasting a notification to the driver.

For example, when the driver of the vehicle 300 turns off the vehicle 300 and leaves the vehicle, the sensing unit 160 of the warning system 100 of the present invention starts to sense the vehicle 300. If the vehicle 300 is hit by another vehicle during this period, the sensing unit 160 will sense the signal shown in FIG. 2 and generate a trigger signal. After receiving the trigger signal, the control unit 180 generates a corresponding event record and stores related event data. In one embodiment, the content of the event data may include the time, intensity, and location of the occurrence of the vibration or disturbance. The event log and event data are stored in the storage unit 140. The warning device 190 prompts the driver about the occurrence of the vibration or disturbance event.

The warning system 100 of the present invention may further include an image capture module 120 electrically connected to the control unit 180 to capture images around the vehicle 300. In one embodiment, the image capturing module 120 may be disposed at a central position in the vehicle 300 near the windshield, but the present invention is not limited thereto. In addition, the sensing unit 160 of the present invention has directivity, and can determine the location where vibration or disturbance occurs, so the image capture module 120 can be controlled to capture related images for a specific location. Furthermore, the storage unit 140 can be used to store the images captured by the image capture module 120. Therefore, the content of the event data may include images of the surroundings of the vehicle 300 when the vibration or disturbance event occurs. The image capture module 120 can be activated as needed, or capture images with different image resolutions. For example, when the control unit 180 receives the trigger signal, the control unit 180 may control the image capture module 120 to start capturing images near the vehicle 300. Furthermore, the control unit 180 can control the image capture module 120 to capture images around the vehicle 300 with an image resolution greater than or equal to the original image resolution.

In addition, the warning system 100 of the present invention may also include a wireless communication module 170 for communicating with a mobile device of the driver of the vehicle 300. For example, when the control unit 180 receives the trigger signal, the warning system 100 can use the wireless communication module 170 to push a notification to the driver's mobile device. In this way, even if the driver is away from the vehicle 300, he can immediately know the occurrence of the event.

The warning system 100 of the present invention can provide different prompts for event records and event data. First, when the driver of the vehicle 300 returns to the vehicle 300, the warning system 100 can let the driver know that the vehicle 300 has experienced an event of vibration or disturbance during the time when the driver 300 left. In this way, the driver of the vehicle 300 can immediately view the place where the vibration or disturbance occurred, or even further view the image around the vehicle 300 captured by the image capture module 120, and immediately respond to the incident (for example, with the incident). The driver of the car discusses matters related to compensation). In addition, the driver of the vehicle 300 can also receive a notification through a mobile device to know that an event has occurred.

In one example, the warning device 190 may be a display device disposed in the vehicle 300. However, the warning device 190 of the present invention is not limited to this; the warning signal of the present invention can also prompt the driver to be notified by sound, light, image, vibration, and text display. For example, the warning device 190 may alert the driver returning to the vehicle 300 by a flashing light-emitting diode or by displaying text on a display. Wherein, when the warning device 190 alerts the driver in a display manner, the control unit 180 can access the image stored in the storage unit 140 and display the image captured by the image capture module 120 when the vehicle 300 is shaken or disturbed during the event. Take the image and play it. This allows the driver of the vehicle 300 to know the situation at the time of the event more immediately.

As described above, the image capture module 120 can set different image resolutions to capture images. For example, when the sensing unit 160 detects that the vehicle 300 is vibrated or disturbed, the control unit 180 may control the image capturing module 120 to capture a dynamic image around the vehicle 300 at the highest image resolution so that the vehicle 300 can Carefully review the relevant information (such as the license plate number of the vehicle in question), and avoid important information that cannot be identified due to insufficient image resolution.
