Description

Technical Field

[0001] The present disclosure relates to the technical field of intelligent vehicles, and particularly to a display system and a vehicle. Background Art

[0002] Head Up Display (HUD) technology was mainly applied in the aviation field in the early days. This technology can project information such as the flight parameters, flight attitude, and navigation data of an aircraft onto a see-through mirror directly in front of the pilot's field of vision. With the development of vehicle intelligence, this technology has been rapidly popularized and promoted in the automotive industry.

[0003] The HUD system is short for the Head Up Display system. Its function is to project important driving information such as speed, navigation data, and driving assistance data onto the windshield in front of the driver, enabling the driver to view the above driving information without lowering the head or turning the head, thereby improving driving safety.

[0004] The current HUD system mainly consists of a display screen, a housing, and a reflection screen. The driving information is projected from the display screen installed on the housing to the reflection screen located on the windshield, and the driver can observe the driving information from the front. However, since the housing is a trough-shaped structure, during the daily use of the vehicle, many users will accidentally drop sundries into the housing, such as coins, USB drives, cards, bills, pens, keys, and even beverages. These sundries may block the driving information. In addition, foreign objects such as rain, dew, and fallen leaves on the vehicle's front windshield will also cause the driver to be unable to clearly see the driving information on the reflection screen, thus posing a safety hazard to driving. Summary of the Utility Model

[0043] Now, various exemplary embodiments of the present disclosure will be described in detail with reference to the accompanying drawings. It should be noted that: Unless otherwise specifically stated, the relative arrangements of components and steps, numerical expressions and values set forth in these embodiments do not limit the scope of the present disclosure.

[0044] Those skilled in the art can understand that terms such as "first" and "second" in the embodiments of the present disclosure are only used to distinguish different steps, devices or modules, etc., and neither represent any specific technical meaning nor indicate an inevitable logical order between them.

[0045] It should also be understood that in the embodiments of the present disclosure, "a plurality" may refer to two or more, and "at least one" may refer to one, two or more.

[0046] It should also be understood that for any component, data or structure mentioned in the embodiments of the present disclosure, unless otherwise clearly defined or given a contrary indication in the context, it is generally understood to be one or more.

[0047] In addition, the term "and / or" in the present disclosure is only a description of the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. In addition, the character " / " in the present disclosure generally represents an "or" relationship between the associated objects before and after.

[0048] It should also be understood that the descriptions of the various embodiments in this disclosure emphasize the differences between the various embodiments, and their similarities or resemblances can be referred to each other. For the sake of brevity, they will not be elaborated one by one.

[0049] Meanwhile, it should be understood that, for the sake of convenience in description, the dimensions of the various parts shown in the drawings are not drawn in actual proportional relationship.

[0050] The following description of at least one exemplary embodiment is actually merely illustrative and in no way restricts the present disclosure and its application or use.

[0051] The technologies and devices known to those of ordinary skill in the relevant fields may not be discussed in detail, but where appropriate, such technologies and devices should be regarded as part of the specification.

[0052] It should be noted that: similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0053] Figure 1 The side view of a display device in the prior art is shown, which mainly consists of three parts: a display screen 1, a housing 2, and a reflective screen 3. The driving information is projected from the display screen 1 onto the reflective screen 3 and then reflected to the human eye 4 again, so that the driver can view the driving information such as speed, navigation information, and driving assistance information. As Figure 1 shown, since the housing 2 is similar to a storage slot, many users will inadvertently throw sundries 7 into the housing 2. The sundries 7 will block part of the area of the display screen 1, making the information in the blocked part unable to be projected onto the reflective screen 4, thus bringing certain potential safety hazards.

[0054] Figure 2 is the structural block diagram of a display system provided by an exemplary embodiment of the present disclosure. Among them, the display system can be applied to a vehicle. As Figure 2 shown, the display system includes a housing 2, a display screen 1 (the display screen 1 and the housing 2 are in a split state in the figure) provided on the housing, a reflective screen 3 disposed opposite to the display screen, at least one sensor 5, and a main control module 6. Among them, the main control module 6 is respectively connected to at least one sensor 5 and the display screen 1.

[0055] Optionally, the display screen 1 is disposed at the inner bottom side of the groove-shaped housing 2 for displaying driving information. The driving information can be generated by the main control module 6 and sent to the display screen 1, for example, it can include but is not limited to information such as vehicle speed and navigation route. Figure 2 The figure shows a schematic diagram of some components of the display system after being split. After the system is assembled, the display screen 1 can be placed in the housing 2 with a bottom, or the display screen 1 can be integrated with the housing 2 as the bottom of the housing 2.

[0056] The reflective screen 3 is disposed in the windshield on the front side of the vehicle to reflect the light projected by the display screen 1 to the driver's seat of the vehicle. Optionally, the reflective screen 3 may be part or all of the windshield on the front side of the vehicle, or may be superimposed on the windshield. The embodiments of the present disclosure do not limit the setting manner of the reflective screen 3.

[0057] At least one sensor 5 emits a detection signal in the working mode and collects detection data based on the reflected signal of the detection signal. The detection data includes at least one of a distance value and a reflected signal intensity, where the distance value represents the distance between the sensor and the signal reflection surface. Optionally, the detection signal may be an optical signal, and correspondingly, the reflected signal intensity is the signal intensity of the reflected light; the detection signal may also be an acoustic signal, and correspondingly, the reflected signal intensity is the signal intensity of the reflected sound wave. The sensor may be an ultrasonic sensor, an infrared sensor, a capacitive sensor, a millimeter-wave radar sensor, a lidar sensor, etc. In the embodiments of the present disclosure, at least one sensor 5 is taken as a time-of-flight (TOF) sensor as an example for illustration, and its detection signal is an optical signal.

[0058] Optionally, at least one sensor 5 may be disposed on other devices in the display system, such as on the housing 2, or may be disposed on an external device, such as on the vehicle body inside the vehicle. The embodiments of the present disclosure do not limit the setting manner of the sensor.

[0059] Optionally, the emission direction of the detection signal of at least one sensor 5 is fixed, for example, fixedly pointing to at least one of the display screen 1, the reflective screen 3, and other display system devices; or the emission direction of the detection signal of at least one sensor 5 is adjustable, for example, it can be switched to point to the display screen 1, the reflective screen 3, and other display system devices. The embodiments of the present disclosure do not limit the emission direction of the detection signal of the sensor.

[0060] Schematically, taking the TOF sensor as an example, at least one sensor 5 continuously emits laser pulses in the direction of the display screen 1 and / or the reflective screen 3. The distance value between each sensor 5 and the display screen 1 and / or the reflective screen 3 can be calculated based on the duration from the emission of the pulsed laser to the return to the sensor, and the reflected signal intensity of the reflected laser is detected. Taking the foreign object detection at the display screen 1 as an example, Figure 3 A schematic diagram of a sensor emitting a detection signal in the direction of the display screen 1 is shown. Among them, the field of view (FOV) 6-1 of the sensor 5-1 disposed on one side of the housing 2 can cover approximately 2 / 3 of the display screen 1. Figure 4The figure shows a schematic diagram of another sensor emitting a detection signal in the direction of the display screen 1. The field of view 6-2 of the sensor 5-2 arranged on the other side of the housing 2 can also cover approximately two-thirds of the display screen 1 (the field of view of the sensor is the detection range of the embodiments of the present disclosure).

[0061] The main control module 6 is used to receive detection data sent by at least one sensor 5, and perform foreign object identification based on the detection data, and output an alarm signal when the detection data indicates the presence of a foreign object. Among them, the main control module 6 may include, but is not limited to, an intelligent sensor processing unit (Intelligent Sensor Processing Unit, ISPU), a central processing unit (Central Processing Unit, CPU), or other forms of processing units with data processing capabilities and / or instruction execution capabilities to implement the processing of sensing data and the generation of alarm signals. The main control module 6 can be connected to the sensor 5 and the display screen 1 through communication interfaces such as a serial peripheral interface (Serial Peripheral Interface, SPI), an RS-232 interface, and a universal asynchronous receiver / transmitter (Universal Asynchronous Receiver / Transmitter, UART).

[0062] The detection data includes at least one of a distance value and a reflection signal intensity. Schematically, the main control module 6 can use a trained deep learning network to input the detection data into the deep learning network to obtain an identification result; or, the main control module 6 can use preset conditions to judge whether there is a foreign object. For example, the preset conditions specify the numerical ranges corresponding to the detection data in the normal (i.e., no foreign object) situation, including a distance range and / or a signal intensity range. If the detection data is not within the numerical range indicated by the preset conditions, it is determined that there is a foreign object currently.

[0063] Optionally, the main control module 6 immediately outputs an alarm signal when a foreign object is detected, or the main control module 6 can further detect the size and / or location of the foreign object, and judge whether the foreign object blocks the display area of the driving information. If it blocks the driving information, an alarm signal is output.

[0064] Schematically, the main control module 6 can send an alarm signal to the display screen 1 to make the display screen display an alarm message to prompt the user to clean the foreign object. The main control module 6 can also send an alarm signal to the audio player of the vehicle to make the audio player play an alarm voice to prompt the user to remove the foreign object. The embodiments of the present disclosure do not limit the alarm method.

[0065] In the embodiments of the present disclosure, by setting at least one sensor in the display system, the at least one sensor emits a detection signal in the working mode, receives the reflected signal of the detection signal, collects detection data based on the reflected signal and sends it to the main control module, so that the main control module performs foreign object recognition based on the detection data. When there is a foreign object blocking display system components such as the display screen and / or the reflection screen, the measured distance value, the intensity of the reflected signal, etc. will change, so that the main control module detects the existence of a foreign object in the display system based on the above changes and issues an alarm, timely reminding the user to clean the foreign object, avoiding the situation that the driving information displayed on the reflection screen is incomplete, thereby improving driving safety.

[0066] In a possible implementation manner, as Figure 5 shown, the display system includes at least two first sensors 5-1 and 5-2.

[0067] The at least two first sensors 5-1 and 5-2 emit detection signals in a first preset detection direction, and the first preset detection direction points to the display screen; the detection ranges 6-1 and 6-2 of the at least two first sensors 5-1 and 5-2 on the display screen 1 cover a proportion of the information display range of the display screen 1 that is greater than a first preset proportion.

[0068] Since the detection range of a single sensor 5 is usually small, and there are angular factors, it is difficult to completely cover the entire area of the display screen 1. Therefore, by setting multiple first sensors on the housing 2, the proportion of the detection ranges of the multiple first sensors on the display screen 1 covering the information display range of the display screen 1 is greater than the first preset proportion. For example, it can cover 80% of the information display range of the central area of the display screen 1, thereby avoiding the visual blind area and the situation of not being able to recognize foreign objects.

[0069] Optionally, the distance between the first sensor and the display screen 1 can be controlled by adjusting the position of the first sensor, and the signal emission direction of the first sensor can be controlled by adjusting the detection angle of the first sensor, so that the proportion of the detection range of the first sensor on the display screen 1 in the information display range reaches the first preset proportion.

[0070] Schematically, Figure 6 in the detection ranges 6-1 and 6-2 of the two first sensors 5-1 and 5-2 can be superimposed to cover the complete display area of the display screen 1, and there is an overlapping area of the detection ranges 6-1 and 6-2 in the middle part of the screen. In this case, no matter where the foreign object falls on the surface of the display screen 1, it can be detected. Figure 4 Only the schematic diagram of setting 2 first sensors is shown. In other possible implementation manners, more first sensors can also be set, and the embodiments of the present disclosure do not limit this.

[0071] Optionally, at least two first sensors 5-1 and 5-2 are in the working mode simultaneously. All the first sensors in the system can simultaneously transmit detection signals and collect data, so as to improve the foreign object recognition efficiency.

[0072] Alternatively,

[0073] at least two first sensors 5-1 and 5-2 alternately work in the working mode according to a preset working cycle, so as to alternately transmit detection signals and collect detection data. In order to reduce the power consumption of the system, at least two first sensors 5-1 and 5-2 can work in a time-sharing manner, and switch between the working mode and the sleep mode according to a preset working cycle.

[0074] For example Figure 5 for the two first sensors 5-1 and 5-2 shown, when the first sensor 5-1 is in the working mode, the first sensor 5-2 can enter the sleep mode; when the first sensor 5-1 enters the sleep mode, the first sensor 5-2 can enter the working mode. Alternatively, the working periods and sleep periods of the first sensors 5-1 and 5-2 may also overlap. The embodiments of the present disclosure do not limit the working modes of at least two first sensors.

[0075] Based on the embodiments of the present disclosure, by setting at least two first sensors on the housing 2, transmitting detection signals in the first preset detection direction where the display screen 1 is located inside the housing 2 and collecting detection data based on the reflected signals, the main control module 6 can identify whether there is a foreign object blocking the display screen 1 inside the housing 2 based on the detection data.

[0076] Since the user obtains driving information by observing the reflection screen 3, if there is a foreign object at the reflection screen 3, it will also pose a certain safety hazard to driving. For example, due to the temperature difference between the inside and outside of the vehicle during the daily use of the vehicle, there may be a phenomenon of water vapor condensation on the reflection screen 3, or there may be rainwater on the outside of the reflection screen 3 on rainy days, or leaves may fall on the outside of the reflection screen 3, etc., thus affecting the reflection of driving information. In a possible implementation manner, as Figure 7 shown, the display system further includes at least one second sensor 5-3.

[0077] At least one second sensor 5-3 transmits detection signals in the second preset detection direction, and the second preset detection direction points to the reflection screen 3, so that the detection signals transmitted by at least one second sensor 5-3 reach the reflection screen 3. The detection range of at least one second sensor 5-3 on the reflection screen 3 covers a proportion of the information display range of the reflection screen 3 that is greater than the second preset proportion.

[0078] Optionally, the distance between the second sensor and the reflection screen 3 can be controlled by adjusting the position of the second sensor, and the signal emission direction of the second sensor can be controlled by adjusting the detection angle of the second sensor, so that the proportion of the detection range of the second sensor on the reflection screen 3 in the information display range reaches a second preset proportion (for example, 80%).

[0079] At least one second sensor 5-3 emits a detection signal in the working mode and acquires detection data based on the reflected signal of the detection signal. The detection data includes the intensity of the reflected signal.

[0080] The main control module 6 is configured to receive the detection data sent by the second sensor 5-3, perform foreign object detection based on the detection data, and output an alarm signal when the detection data indicates the presence of a foreign object 8.

[0081] Optionally, the detection signal can be an optical signal, and the corresponding intensity of the reflected signal is the signal intensity of the reflected light; the detection signal can also be a sound signal, and correspondingly, the intensity of the reflected signal is the signal intensity of the reflected sound wave. In the embodiments of the present disclosure, the second sensor 5-3 is taken as a TOF sensor as an example for illustration. Its detection signal is an optical signal, and the detection data includes the signal intensity of the reflected light. Since foreign objects such as water vapor and rain and dew will reduce the refraction degree of the detection signal, resulting in an increase in the intensity of the reflected signal, foreign object recognition can be performed based on the change of the intensity of the reflected signal.

[0082] Schematically, taking the TOF sensor as an example, the second sensor 5-3 continuously emits laser pulses in the direction of the display screen 3, and the intensity of the reflected signal of the reflected laser can be detected. As Figure 7 shown, the detection range 6-3 of the second sensor 5-3 can fall within the middle area of the reflection screen 3.

[0083] Schematically, the main control module 6 can use the trained deep learning network to input the detection data sent by the second sensor 5-3 into the deep learning network to obtain the recognition result; or, the main control module 6 can use preset conditions to judge whether there is a foreign object. For example, the preset conditions specify the numerical range corresponding to the detection data in the normal case (that is, there is no rain and dew or the rain and dew density is low outside the reflection screen 3), including the distance range and / or the signal intensity range. If the detection data is not within the numerical range indicated by the preset conditions, it is determined that there is a foreign object currently.

[0084] Optionally, when the main control module 6 detects a foreign object, it immediately outputs an alarm signal. Alternatively, the main control module 6 can further detect the size of the foreign object (rain and dew density, degree of water vapor condensation), and determine whether the foreign object blocks the display area of the driving information. If the driving information is blocked, an alarm signal is output. In addition, the main control module 6 can also be connected to the vehicle's wiper controller. When a foreign object is detected based on the detection signal of the second sensor, a wiper control signal is sent to the wiper controller to automatically activate the wiper to clean the front windshield.

[0085] Optionally, since the detection range of a single second sensor is usually small and there are angular factors, it is difficult to completely cover the entire area of the reflection screen 3. To improve the recognition rate of foreign objects on the reflection screen 3, at least two second sensors can be set so that the detection ranges of multiple second sensors can completely cover the reflection screen 3 after being superimposed, thereby avoiding blind spots in the field of view and the situation where foreign objects cannot be recognized. At least two second sensors are in the working mode at the same time, or at least two second sensors alternately enter the working mode according to a preset working cycle to alternately transmit detection signals and collect detection data, so as to reduce the power consumption of the display system.

[0086] Optionally, at least one sensor 5 can be set on the inner wall of the housing 2. As Figure 2 shown, the housing 2 is arranged above the display screen 1. By directly setting at least one sensor 5 on the inner wall of the housing 2 at a certain angle, the detection range of at least one sensor 5 can fall on the display screen 1 and / or the reflection screen 3.

[0087] Optionally, at least one sensor 5 is arranged on the outside of the housing 2, and at least one light-transmitting hole is arranged on the housing 2. The light-transmitting hole is used to transmit the detection signal emitted by at least one sensor 5 and the reflected signal of the detection signal. The detection signal emitted by at least one sensor 5 enters the inside of the housing 2 through at least one light-transmitting hole, which can avoid blocking the light emitted by the display screen 1 when the sensor 5 is arranged inside the housing 2, resulting in partial driving information being blocked. The number of light-transmitting holes is greater than or equal to the number of sensors arranged on the outside of the housing 2. As Figure 5 shown, light-transmitting holes are respectively arranged on both sides of the housing 2. The first sensor 5-1 and the first sensor 5-2 are respectively arranged near the light-transmitting holes on both sides of the housing 2, and the detection signals of the first sensor 5-1 and the first sensor 5-2 enter the housing 2 through the light-transmitting holes, so that the detection ranges 6-1 and 6-2 can cover the bottom side inside the housing 2, that is, the area where the display 1 is located.

[0088] Optionally, when multiple sensors 5 are included in the system, a part of the sensors 5 can be arranged on the inner wall of the housing 2, and another part of the sensors 5 can be arranged on the outside of the housing 2 and the detection signals enter the inside of the housing 2 through at least one light-transmitting hole.

[0089] Schematic Figure 8 Figure 8 shows a schematic diagram of a display system provided with a first sensor and a second sensor at the same time. As shown in the figure, a first sensor 5-1, a first sensor 5-2 and a second sensor 5-3 are provided on a housing 2. Among them, the detection signals of the first sensor 5-1 and the first sensor 5-2 enter the interior of the housing 2 through the light-transmitting holes of the housing 2, and the reflected signals are received through the light-transmitting holes. The detection range 6-1 of the first sensor 5-1 and the detection range 6-2 of the first sensor 5-2 can cover the bottom of the housing 2, that is, the area where the display screen is located, after being superimposed. A second sensor 5-3 is also provided on the housing 2. The detection signal of the second sensor 5-3 reaches a reflecting screen 3 through the light-transmitting hole on the housing 2, and the reflected signal is received through the light-transmitting hole. The detection range 6-3 of the second sensor 5-3 covers the middle area of the reflecting screen 3.

[0090] Optionally, in the display system of the present disclosure embodiment, the first sensor can be used alone to detect foreign objects at the display screen 1, the second sensor can be used alone to detect foreign objects at the reflecting screen 3, or the first sensor and the second sensor can be used at the same time to take into account the detection of foreign objects at the display screen 1 and the reflecting screen 3.

[0091] In a possible implementation manner, a main control module 6 is configured to send an alarm signal to the display screen 1 after generating the alarm signal. The display screen 1 is configured to display alarm information based on the alarm manner indicated by the alarm signal. For example, the alarm signal (the first alarm signal) generated when a foreign object is recognized based on the detection data of the first sensor is different from the alarm signal (the second alarm signal) generated when a foreign object is recognized based on the detection data of the second sensor. The display screen 1 generates corresponding alarm information based on the specific alarm signal type. For example, when receiving the first alarm signal, the text information of "Please take out the item in the groove" is displayed, and when receiving the second alarm signal, the text information of "Please turn on the windshield wiper to clean the windshield" is displayed to prompt the user to remove the corresponding foreign object in time.

[0092] In another possible implementation manner, the main control module 6 is connected to an audio playback module of the vehicle.

[0093] The main control module 6 is configured to send an alarm signal to the audio playback module after generating the alarm signal; the audio playback module is configured to play alarm information based on the alarm signal. By alarming the user in the way of audio playback, it is possible to prevent the alarm information displayed on the reflecting screen 3 from blocking the driving information.

[0094] Optionally, at least one sensor in the system can be fixedly arranged on the housing 2 by at least one of screwing, bonding, clamping or welding.

[0095] The display system provided by the embodiment of the present disclosure is used for a vehicle. AsFigure 9 As shown, it shows a structural block diagram of a vehicle provided by an exemplary embodiment of the present disclosure. Among them, the vehicle includes the display system 901, the connector 902, and the vehicle power supply 903 provided in any of the above embodiments. The reflective screen in the display system 901 is disposed on the front windshield of the vehicle.

[0096] Among them, the power management module in the display system 901 is electrically connected to the vehicle power supply 903 through the connector 902.
