[0054] It should be noted in particular that any symbols and / or numbers in the specification that are not marked in the accompanying drawings are not drawing marks.
[0055] The optional embodiments of the present application are described in detail below with reference to the accompanying drawings.
[0056] The embodiment provided in this application is an embodiment of a system for reminding rear passengers to get off a vehicle.
[0057] The embodiments of the present application are described in detail below with reference to FIG1 to FIG3 .
[0058] As shown in FIG1 , a system for reminding rear passengers to get off a vehicle includes a sensor component, an image acquisition component, a reminder component, and a control module.
[0059] The sensor assembly, located at the rear of the vehicle, senses the infrared radiation source behind the vehicle and the distance between the infrared radiation source and the vehicle, generating a sensing signal. This sensing signal includes information about the infrared radiation source and the distance between the infrared radiation source and the vehicle.
[0060] Specifically, the sensor assembly may include an infrared sensor and a distance sensor.
[0061] Infrared sensors are used to sense infrared radiation sources and generate radiation sensing signals. For example, two infrared sensors may be installed on the left and right sides of the rear of a car. This allows one infrared sensor to sense the left rear side of the car, while the other can sense the right rear side.
[0062] It should be noted that the rear of the car refers to the front and rear of the car.
[0063] The distance sensor is used to measure the distance between the infrared radiation source and the car and generate a distance perception signal. The distance sensor is installed at the rear of the car, so that the distance sensor can monitor the distance between the infrared radiation source and the car.
[0064] The radiation sensing signal and the distance sensing signal constitute the sensing signal.
[0065] It should be noted that the infrared sensor and the distance sensor are both conventional sensors, and since the sensing ranges of different models of infrared sensors and distance sensors are different, the number of infrared sensors and distance sensors at the rear of the car can be set as needed, and the number of infrared sensors and distance sensors in this application is not limited.
[0066] The image acquisition component is arranged at the rear of the car and is used to collect images of infrared radiation sources and form image signals.
[0067] Specifically, the image acquisition component may be a camera device, such as a camera. That is, the camera is used to capture the image of the rear end of the vehicle and convert the image into an image signal for transmission.
[0068] This embodiment does not impose any restrictions on the specifications and models of the camera device, as long as it can capture images and ensure that the resolution of the captured images meets the requirements.
[0069] It should be noted that the sensing signals collected by the sensor assembly can only sense the infrared radiation source and the distance between the infrared radiation source and the car, that is, locate the infrared radiation source, but cannot determine whether the infrared radiation source is a pedestrian, because pedestrians on the road can only serve as one type of infrared radiation source, and vehicles and animals on the road can also become infrared radiation sources. Therefore, after the sensor assembly collects the sensing signals, it is necessary to use the image acquisition assembly to capture an image of the infrared radiation source in order to further determine whether it is a pedestrian based on the image. In other words, the present application combines infrared sensing technology and high-definition cameras for pedestrian recognition, and uses a combination of infrared sensors and high-definition cameras to achieve accurate recognition and positioning of pedestrians behind the car. This enables the rear-seat passenger disembarkation reminder system to accurately identify pedestrians at night or in complex environments, thereby improving the reliability and accuracy of pedestrian reminders.
[0070] The reminder component, placed in the rear seat of a vehicle, can generate a warning that is noticeable to rear passengers. Upon noticing this warning, passengers will be alerted to the presence of pedestrians behind the vehicle. This action allows them to turn around or open the door slightly to observe the rear of the vehicle, confirming the presence of pedestrians, thereby avoiding or reducing traffic accidents and improving driving safety. The reminder component's method of notification should be easily perceived by passengers, and this awareness can be achieved through hearing, vision, or touch.
[0071] For example, the reminder component can be a speaker, which is placed in the rear vehicle of the car; the speaker responds to the working signal and emits a warning sound. The speaker is placed in the rear vehicle to use sound to remind passengers and reduce the impact of the reminder on the driver.
[0072] Furthermore, the number of the speakers may be two, and the two speakers include a first speaker and a second speaker.
[0073] The first and second speakers are separately positioned in the rear passenger compartment of the vehicle, with the first speaker positioned near one rear door and the second speaker positioned near the other rear door, so that the first speaker forms a first sound zone at the rear door, and the second speaker forms a second sound zone at the rear door. For example, the first and second speakers are positioned on the vehicle doors. Thus, the first and second speakers form a first and second sound zones with the nearest vehicle seat, respectively. When a passenger is seated in the first sound zone, the warning sound emitted by the first speaker in the first sound zone will be perceived by that passenger, while having little impact on other passengers and the driver in the vehicle who are not in the first sound zone. The same applies to the second sound zone, which will not be further described.
[0074] The first and second speakers are connected to the control module, and the first or second speaker emits a warning sound in response to the operation signal. The first and second speakers can operate independently, that is, the first or second speaker can be used to alert passengers in different seats in the car, so that passengers in different seats can be alerted separately without interfering with each other.
[0075] It should be noted that the audio system can be obtained by adjusting the wiring harness or program of the original audio system in the car, and the present application does not limit the adjustment of the wiring harness or program.
[0076] In another example, the reminder component can be an ambient light installed in the rear passenger compartment of a vehicle. In response to an operating signal, the ambient light emits different light colors, strobe patterns, and / or flashing frequencies. This lighting change serves as a reminder to passengers, and the impact of this reminder on the driver. For example, when a passenger can safely open a door, the ambient light flashes green; if opening the door is dangerous, the ambient light flashes red.
[0077] Furthermore, the number of the atmosphere lights is at least two; the two atmosphere lights include a first atmosphere light and a second atmosphere light;
[0078] The first and second ambient lights are separately arranged in the rear vehicle of the vehicle, with the first ambient light being close to one rear door of the vehicle, and the second ambient light being close to the other rear door of the vehicle, so that the first ambient light forms a first ambient zone on the rear door of the vehicle, and the second ambient light forms a second ambient zone on the rear door of the vehicle. For example, the first and second ambient lights may be respectively arranged on the doors on both sides along the length of the vehicle, and may also be arranged at the position where the doors are unlocked. The present application does not limit the positions of the first and second ambient lights on the doors, as long as they can form a warning reminder for the passengers.
[0079] The first and second ambient lights are each connected to a control module, and the first or second ambient light emits different light colors, strobe patterns, and / or flashing frequencies in response to an operating signal. In other words, the operating signal includes operating parameters for controlling the first and second ambient lights, and the first and second ambient lights can be operated using the operating signal.
[0080] It should be noted that the first ambient light and the second ambient light can work independently, that is, the first ambient light and the second ambient light are used to remind passengers in different seats in the car, so that passengers in different seats can be reminded individually without interfering with each other.
[0081] The ambient light can be an ambient light strip, an independent light, or a combination of multiple independent lights. In addition, the ambient light can be the existing ambient light in the rear of the car. The ambient light in the rear of the car can not only be used to remind pedestrians behind the car, but also has a lighting function, which improves the comfort of passengers. It makes the reminder of pedestrians behind the car more intuitive and comfortable, and avoids the problem of distracting the driver's attention. At the same time, only the passengers corresponding to the fixed doors are reminded, and the doors that can be opened safely are not disturbed, preventing interference and misjudgment of other passengers. In other words, since the first ambient light and the second ambient light are controlled independently, when the pedestrian behind the car affects the opening of the door on one side, the ambient light on this side will remind, while the ambient light on the other side where the door can be opened safely will not remind.
[0082] In another example, the reminder component can be a vibrator, which is disposed in the rear vehicle compartment of a vehicle. The vibrator generates vibrations in response to the operating signal. The vibrator can be placed in the rear seat of the vehicle to alert passengers using vibrations while reducing the impact of the reminder on the driver.
[0083] Furthermore, there are at least two vibrators; the two vibrators include a first vibrator and a second vibrator.
[0084] The first vibrator and the second vibrator are separately arranged in the rear vehicle of the car, and the first vibrator is close to the seat on one side of the rear row of the car, and the second vibrator is close to the seat on the other side of the rear row of the car, so that the first vibrator forms a first vibration zone on the seat on one side of the door of the car, and the second vibrator forms a second vibration zone on the seat on one side of the door of the car. For example, the first vibrator is placed in the left seat in the rear row of the car, close to the door, and the second vibrator is placed in the right seat in the rear row of the car, close to the door. When the first vibrator and the second vibrator are working, the passengers sitting there will feel the vibration. In this way, the vibration method can be used to remind passengers that there is something behind the car and they need to be careful when getting off. For another example, the first vibrator is placed in the backrest of the left seat near the door, and the second vibrator is placed in the backrest of the right seat in the rear row of the car, close to the door, which can also remind passengers. This application does not limit the placement of the vibrators on the seats or where they are placed. It is sufficient that they can generate vibration and be felt by the passengers.
[0085] The first vibrator and the second vibrator are each connected to the control module, and the first vibrator or the second vibrator vibrates in response to an operating signal. The frequency of the vibration can be adjusted as needed. For example, the closer a pedestrian behind the vehicle is to the vehicle door, the higher the vibration frequency. The operating signal carries the vibrator's operating mode (parameters), so that the vibrator vibrates in response to the operating signal.
[0086] In this embodiment, the sound, ambient light and vibrator included in the reminder component can be combined as needed, that is, they can be used separately or in free combination.
[0087] The control module is connected with the reminder component, the sensor component and the image acquisition component respectively, and a warning strategy is preset in the control module.
[0088] Among them, the control module is configured to: receive perception signals and image signals, and compare the perception signals and image signals with the warning strategy respectively. If they fall within the scope of the warning strategy, a working signal is sent to the reminder component so that the reminder component responds to the working signal and issues a warning action.
[0089] The control module can be composed of a microcontroller or single-chip microcomputer. Users can configure the operating modes of the audio, ambient lighting, and vibrator on a control panel connected to the control module. In other words, users can customize reminder strategies, which can include audio volume and playback content, ambient lighting color, strobe pattern or flashing frequency, and vibrator vibration frequency. Furthermore, users can include drivers or passengers.
[0090] The control module can interface with other systems of the car. For example, the control module is connected to the car's safety system or warning system (the safety system or warning system is an existing system of the car), and is linked with the car's active safety system or warning system when necessary.
[0091] The warning strategy is a strategy unit pre-set in the control module. For example, an existing image recognition system can be configured for the warning strategy so that after the control module receives the image signal, it uses the image recognition system to identify the image carried in the image signal. A deep learning algorithm can be used to identify and analyze pedestrian images, extract pedestrian features, achieve accurate pedestrian recognition, and then determine whether the infrared radiation source in the image is a pedestrian.
[0092] In addition, the alert strategy also has alert parameters, such as location, quantity, and action status.
[0093] Among them, the position parameter can be compared with the distance of the infrared radiation source carried in the perception signal. When it is less than the threshold set by the position parameter, it can be determined that the pedestrian will affect the passenger's door opening.
[0094] The quantity parameter is compared with the number of infrared radiation sources in order to determine the number of pedestrians. That is to say, the quantity parameter is compared with the number of infrared radiation sources, and then the warning action is adjusted according to the infrared radiation sources. For example, the more infrared radiation sources, the more intense the warning action, so as to attract the attention of passengers. The quantity parameter here can set the threshold value corresponding to the quantity, or it can be said that when there is one pedestrian, the warning action is one type, when there are two pedestrians, the warning action is another type, and if there are more people, the corresponding warning action can be set.
[0095] The action state parameter is compared with the speed of the pedestrian in the image signal, and a threshold is set for the action state parameter. When the speed of the pedestrian in the image signal is greater than the set threshold, it is judged that the pedestrian may affect the opening of the door. It should be noted that the speed of the pedestrian can be obtained by using the changes in the pedestrian in the current frame image and the previous frame image or the set time frame image in the image signal. The changes include changes in size and / or relative changes between the pedestrian and the surrounding environment. This judgment action can be completed in the image recognition system. In addition, the image recognition system can be set not only in the strategy unit, but also in the control module. The present application does not limit the setting location of the image recognition system.
[0096] It should be noted that the various parameters in the warning strategy can be used in combination. For example, the position parameter is used to locate pedestrians, the number parameter is used to determine the number of pedestrians, and the action status parameter is used to determine the distance walked by pedestrians in the future time period and whether it will affect the opening of the car door. In this way, the various parameters are combined and comprehensively judged to form a warning action signal.
