Description

Technical Field

[0001] The present application relates to the technical field of vehicles, and particularly to a visual prompting method, an electronic device, and a vehicle. Background Art

[0002] Motion sickness is a common form of motion sickness phenomenon, mainly because the vestibular system in the human inner ear is continuously and complexly stimulated when taking a means of transportation, and the information seen by the eyes is inconsistent with the motion information perceived by the vestibular system, resulting in the brain receiving chaotic signals, and then triggering a series of autonomic nervous system reactions.

[0003] In the related art, mainly by setting a display screen, the motion sickness phenomenon of passengers is presented in the form of images, but the motion sickness situations that this method can handle are relatively simple, and the anti-motion sickness effect is not good.

[0062] In the embodiments of the present application, the terms "first" and "second" are only used for descriptive purposes, and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0063] In the embodiments of the present application, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, such that a process, method, article or device comprising a series of elements not only includes those elements but also includes other elements not expressly listed, or further includes elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "comprising a..." does not exclude the presence of additional identical elements in the process, method, article or device comprising the element.

[0064] "A and / or B" includes the following three combinations: only A, only B, and the combination of A and B.

[0065] In a related technology, a double-row flowing lighting method is used through an in-vehicle display device to display the driving trend of the vehicle. When the vehicle is in a forward decelerating state, if the user can see the scenery outside the window at the same time, the user will see two conflicting flowing scenes at the same time. One scene is that the scenery outside the window flows in the opposite direction of the vehicle driving, resulting in the inability to accurately prompt the user of the specific driving state of the vehicle.

[0066] To solve the above technical problems, the embodiments of the present application provide a visual prompt method, the idea of which is: to set light strips within the visual range of the passengers in the vehicle, and to be able to control the lighting state of the light strips in the vehicle according to the vehicle driving data, wherein the lighting state of the light strips is used to prompt the change of the vehicle state to relieve the vestibular conflict of the passengers. Thus, the present application reduces the vestibular conflict by intuitively prompting the vehicle state, thereby relieving the motion sickness phenomenon.

[0067] The visual prompt method, electronic device and vehicle provided by the present application will be introduced below.

[0068] In some embodiments, the present application provides a visual prompt system, as Figure 1 shown, the visual prompt system 100 includes: a data acquisition device 101, a control device 102, and a light strip 103.

[0069] Among them, the data acquisition device 101 and the control device 102, and the control device 102 and the light strip 103 can be connected and transmit data through wired or wireless (such as Bluetooth, WIFI, etc.) methods respectively, and this application does not limit this.

[0070] In some embodiments, the data acquisition device 101 is used to obtain the driving state data of the vehicle and send the driving state data to the control device 102.

[0071] Among them, the driving data is used to determine the lighting state of the light strip 103.

[0072] In some embodiments, the driving state data of the vehicle includes at least one of the following: direction state data, speed state data.

[0073] Exemplarily, the data acquisition device 101 includes, but is not limited to, a direction sensor (or steering wheel sensor) for collecting direction state data, a speed sensor and an acceleration sensor for collecting speed state data, and other sensor devices for obtaining the driving state of the vehicle.

[0074] In some embodiments, the control device 102 is used to determine and control the lighting state of the light strip 103 based on the driving state data.

[0075] In some embodiments, the control device 102 is used to determine the position of the direction indicator lights in the light strip according to the direction state data and control the lighting state of the direction indicator lights.

[0076] In some embodiments, the control device 102 is used to determine the position of the direction indicator lights in the light strip according to the speed state data and control the lighting state of the direction indicator lights.

[0077] Exemplarily, the control device 102 can be a vehicle controller, such as an MCU, an ECU, a programmable logic control unit, etc.

[0078] In some embodiments, the light strip 103 responds to the control signal of the control device 102 and shows different lighting states for passengers.

[0079] In some embodiments, the light strip 103 includes at least one light strip.

[0080] In some embodiments, the light strip 103 includes a first light strip on the left side of the occupant and a second light strip on the right side of the occupant.

[0081] Exemplarily, as Figure 2 shown, the light strip can be installed on the armrests of the seats on both the left and right sides of the occupant, or installed at the bottom of the occupant seat. This application does not limit the position of the light strip. In actual applications, the light strip is within the visual range of the passengers in the vehicle.

[0082] Exemplarily, the light strip 103 can be an LED light strip composed of multiple light-emitting diode beads. For ease of installation, the light strip 103 can also be a deformable flexible LED light strip, which is composed of multiple light-emitting diode beads connected to a flexible circuit board through connectors and can meet the requirements of various shape changes.

[0083] Figure 3 The following is a schematic structural diagram of a light strip provided by an embodiment of the present application, as Figure 3 shown, the light strip 103 includes a lamp shade 1031, LED beads 1032, and a flexible circuit board 1033.

[0084] The system architecture and business scenarios described in the embodiments of the present disclosure are for more clearly illustrating the technical solutions of the embodiments of the present disclosure, and do not constitute a limitation on the technical solutions provided by the embodiments of the present disclosure. Those of ordinary skill in the art know that with the evolution of the network architecture and the emergence of new business scenarios, the technical solutions provided by the embodiments of the present disclosure are equally applicable to similar technical problems.

[0085] Above, a visual prompt system in the embodiments of the present application has been introduced.

[0086] The visual prompt method in the embodiments of the present application can be applied to the processing device 102 in the above visual prompt system. The following introduces the visual prompt method provided by the embodiments of the present application with reference to the accompanying drawings.

[0087] As Figure 4 shown, the visual prompt method includes the following steps:

[0088] S100. Obtain the driving state data of the vehicle.

[0089] In some embodiments, the driving state data of the vehicle includes at least one of the following: direction state data, speed state data.

[0090] In some embodiments, the direction state data can be determined based on the driver's steering operation of the vehicle's steering wheel. Exemplarily, a steering angle sensor of the steering wheel can measure the driver's steering operation of the vehicle's steering wheel. For example, data such as the actual rotation direction, steering amplitude, and rotation speed of the steering wheel.

[0091] In some embodiments, the speed state data is used to reflect the driving speed of the vehicle and its changes. For example, acceleration data, and the vehicle obtains the speed state data through a speed sensor.

[0092] S200. Based on the driving state data, control the lighting state of the in-vehicle light strip.

[0093] Among them, the above light strip is within the visual range of the passengers in the vehicle.

[0094] Among them, the lighting state of the above light strip is used to prompt the change of the vehicle state to relieve the vestibular conflict of passengers.

[0095] It can be understood that when the information perceived by the vestibular organ of the human body is inconsistent with the information perceived by other sensory organs (such as vision), the brain cannot accurately integrate these contradictory information, resulting in a sense of discomfort or symptoms such as motion sickness. Based on this visual prompt method of controlling the lighting state of the in-vehicle light strip according to the driving state of the vehicle, this inconsistent situation of information can be reduced, thereby relieving the vestibular conflict.

[0096] It should be noted that according to the description of step S100, the driving state data of the vehicle can include various data. Since different types of data indicate different driving states of the vehicle, different lighting states of the in-vehicle light strip can be determined based on different types of driving state data.

[0097] The following introduces different ways to determine the lighting state of the in-vehicle light strip based on the driving state data.

[0098] As Figure 5 shown, when the driving state data includes direction state data, step S200 can be specifically implemented as the following step S301:

[0099] S301. According to the direction state data, determine the position of the direction indicator light in the light strip and control the lighting state of the direction indicator light.

[0100] Among them, the direction indicator light is used to reflect the steering operation state of the vehicle.

[0101] In some embodiments, the direction state data includes at least one of the following: steering indication, steering direction, and steering amplitude.

[0102] Among them, the steering indication is used to indicate whether the vehicle is performing a steering operation.

[0103] It can be understood that determining the position of the direction indicator light in the light strip according to the direction state data and controlling the lighting state of the direction indicator light can provide a visual prompt of the direction state of the vehicle for passengers, thereby relieving the motion sickness phenomenon caused by the conflict between vision and the vestibular organ in direction perception.

[0104] In some embodiments, if the steering wheel of the vehicle does not rotate, it means that the vehicle is not performing a steering operation, and in this case, the vehicle is in a straight-ahead state.

[0105] Correspondingly, determining the position of the direction indicator light in the light strip according to the direction state data can be specifically implemented as: when the steering indication is used to indicate that the vehicle is not performing a steering operation, determining the position of the direction indicator light as the position of the central lamp bead of the light strip.

[0106] In some embodiments, if the steering wheel of the vehicle rotates, it indicates that the vehicle has performed a steering operation. In this case, the vehicle is in a non-straight state and the direction has deviated. Therefore, the steering situation of the vehicle in terms of direction can be indicated by the deviation of the position of the direction indicator light.

[0107] Correspondingly, as Figure 6 shown, according to the direction status data, determining the position of the direction indicator lights in the light strip can be specifically implemented as the following steps S401 - S403:

[0108] S401. When the steering indication is used to indicate that the vehicle performs a steering operation, based on the steering direction, determine the position offset direction of the direction indicator lights in the light strip.

[0109] In some embodiments, when the vehicle is non - straight, the steering indication is used to indicate that the vehicle has performed a steering operation.

[0110] In some embodiments, the steering direction of the vehicle includes a left turn and a right turn.

[0111] In some embodiments, the light strip includes a first light strip on the left side of the occupant and a second light strip on the right side of the occupant. Based on the steering direction, determining the position offset direction of the direction indicator lights in the light strip can be specifically implemented as the following steps a1 or a2:

[0112] a1. When the steering direction is a left turn, determine that the position offset direction of the direction indicator lights in the first light strip is the first direction, and the position offset direction of the direction indicator lights in the second light strip is the second direction.

[0113] a2. When the steering direction is a right turn, determine that the position offset direction of the direction indicator lights in the first light strip is the second direction, and the position offset direction of the direction indicator lights in the second light strip is the first direction.

[0114] In some embodiments, the light strip includes a single light strip. When the steering direction is a left turn, the position offset direction of the direction indicator lights in the light strip is the first direction; when the steering direction is a right turn, the position offset direction of the direction indicator lights in the light strip is the second direction. Among them, when the light strip includes a single light strip, the offset direction of the direction indicator lights corresponding to the steering direction can be determined according to actual needs. This embodiment is only an exemplary implementation.

[0115] In some embodiments, the above - mentioned first direction is the direction towards the front of the vehicle, and the above - mentioned second direction is the direction towards the rear of the vehicle.

[0116] It can be understood that the way of setting two light strips can enhance the vehicle turning prompt effect. Through the offset of the direction indicator lights on both sides of the light strips in different directions, the turning intention of the vehicle can be intuitively shown to the passengers, reducing the vestibular conflict of the passengers.

[0117] S402. Determine the position offset of the direction indicator lights in the light strip based on the turning amplitude.

[0118] Among them, the above position offset is used to indicate the position offset relative to the central lamp bead of the light strip.

[0119] In some embodiments, the position offset of the direction indicator lights in the light strip is positively correlated with the turning amplitude. The greater the turning amplitude of the vehicle, the greater the position offset of the direction indicator lights in the light strip.

[0120] In some embodiments, based on the current turning amplitude of the vehicle, the maximum turning amplitude of the vehicle, and the number of the first specified lamp beads in the light strip, determine the position offset of the direction indicator lights in the light strip. Among them, the first specified lamp bead is the lamp bead specified for prompting the direction in the light strip.

[0121] Exemplarily, the position offset of the direction indicator lights in the light strip satisfies the following formula:

[0122]

[0123] Among them, N is the position offset of the direction indicator lights in the light strip, N0 is the number of the first specified lamp beads in the light strip, a is the current vehicle speed, and θ0 is the maximum turning amplitude of the vehicle. Among them, the specific values of M0 and θ0 in this application are not limited. In practical applications, M0 can be determined according to the product requirements of the light strip, and θ0 can be determined according to the actual test of the vehicle.

[0124] S403. Determine the position of the direction indicator lights based on the position offset direction and the position offset.

[0125] As Figure 7 shown, when the driving state data includes speed state data, step S200 can be specifically implemented as the following steps S501 - S502:

[0126] S501. Determine the number and flow direction of the acceleration amplitude indicator lights in the light strip according to the speed state data.

[0127] Among them, the acceleration amplitude indicator lights are used to prompt the passengers about the acceleration change of the vehicle.

[0128] In some embodiments, the flow direction represents the direction from the position of the first lit indicator light to the position of the last lit indicator light among at least one acceleration amplitude indicator light.

[0129] In some embodiments, the flow direction includes the first direction and the second direction described above.

[0130] It should be understood that since the vestibular organs mainly sense the changes in speed and transmit the changes to the brain, thus generating different degrees of physical sensations, such as the forward inclination feeling during acceleration or the backward inclination feeling during deceleration, the number of illuminated lights of the indicator light can be determined based on the magnitude and direction of the acceleration data.

[0131] In some embodiments, the speed state data includes the magnitude of the acceleration of the vehicle. According to the speed state data, determining the number of acceleration amplitude indicator lights in the light strip can be specifically implemented as: determining the number of acceleration amplitude indicator lights in the light strip based on the ratio between the acceleration of the vehicle and the maximum acceleration of the vehicle.

[0132] A possible implementation is that the number of acceleration amplitude indicator lights in the light strip is positively correlated with the ratio. When the vehicle acceleration is small, a small number of indicator lights are illuminated; when the vehicle acceleration is large, the number of indicator lights increases.

[0133] In some embodiments, the number of acceleration amplitude indicator lights satisfies the following formula:

[0134]

[0135] Where N is the number of acceleration amplitude indicator lights, N0 is the preset maximum number that can be used as acceleration amplitude indicator lights, a is the current speed of the vehicle, and a0 is the maximum acceleration of the vehicle. Here, the specific values of N0 and a0 in this application are not limited. In actual applications, N0 can be determined according to the product requirements of the light strip, and a0 can be determined according to the actual test of the vehicle.

[0136] Exemplarily, assuming that the number of acceleration amplitude indicator lights corresponding to the maximum acceleration of the vehicle is 10, when the vehicle is traveling at a constant speed, that is, when the acceleration is 0, 0 indicator lights are illuminated; when the vehicle accelerates at 30% of the maximum acceleration, 3 indicator lights are illuminated; when the vehicle accelerates at 50% of the maximum acceleration, 5 indicator lights are illuminated; when the vehicle accelerates at 70% of the maximum acceleration, 7 indicator lights are illuminated; when the vehicle's acceleration reaches the maximum, all 10 indicator lights are illuminated.

[0137] It can be understood that in actual situations, the vehicle acceleration may have various degrees of changes. The way that the number of indicator lights is positively correlated with the ratio can finely divide and quantify the magnitude of the acceleration, providing different degrees of visual cues for passengers, thus adapting to the driving state of the vehicle under different accelerations, reducing vestibular conflict, and alleviating motion sickness.

[0138] In some embodiments, the speed state data includes the direction of the vehicle's acceleration. Based on the speed state data, determining the flow direction of the acceleration amplitude indicator lights in the light strip can be specifically implemented as: determining the flow direction of the acceleration amplitude indicator lights in the light strip based on the direction of the vehicle's acceleration.

[0139] A possible implementation is that the flow direction of the acceleration amplitude indicator lights is opposite to the direction of the vehicle's acceleration. This way can serve as a visual cue to reduce the vestibular conflict caused by acceleration changes and alleviate the phenomenon of motion sickness.

[0140] Exemplarily, when the vehicle is accelerating, the flow direction of the acceleration amplitude indicator lights is the second direction; when the vehicle is decelerating, the flow direction of the acceleration amplitude indicator lights is the first direction.

[0141] It can be understood that by analyzing the acceleration direction, the change in the vehicle's motion state can be presented to the passengers in an intuitive visual form (the flow direction of the light strip). This reverse flow direction indicator light can serve as a balancing factor to help the brain better integrate the signals from the vestibular organ and the visual organ, thereby reducing the vestibular conflict.

[0142] S502. Control the lighting state of the acceleration amplitude indicator lights according to the number and flow direction of the acceleration amplitude indicator lights in the light strip.

[0143] In some embodiments, according to the number and flow direction of the acceleration amplitude indicator lights in the light strip, control the lamp beads after the direction indicator lights in the light strip to be lit in sequence. Among them, the brightness of the lit lamp beads increases in sequence.

[0144] In some embodiments, the lamp beads are lit in sequence at a preset time interval. For example, one lamp bead is lit every 200 ms.

[0145] As a possible implementation, according to the number and flow direction of the acceleration amplitude indicator lights in the light strip, all the lamp beads are lit in sequence, that is, the first lamp bead is lit first, after a preset time interval, the second lamp bead is lit, and the first lamp bead remains lit continuously. All the lamp beads are lit in this order to form a complete lit light strip.

[0146] As another possible implementation, according to the number and flow direction of the acceleration amplitude indicator lights in the light strip, starting from the first lamp bead, after a preset time interval, the second lamp bead is lit, and the first lamp bead is extinguished. The lighting of each acceleration amplitude indicator light is completed in this order.

[0147] In some embodiments, the position of the first light bead of the acceleration amplitude indicator light that needs to be lit can be determined according to the position of the direction indicator light and the flowing direction of the acceleration amplitude indicator light. For example, it can be the first light bead in the corresponding flowing direction starting from the direction indicator light.

[0148] Exemplarily, Figure 8 shows the lit state of the in-vehicle light strip when the vehicle is moving straight at a constant speed (acceleration is 0); Figure 9 shows the lit state of the in-vehicle light strip when the vehicle is accelerating straight (acceleration is not zero); Figure 10 shows the lit state of the in-vehicle light strip when the vehicle is decelerating straight (acceleration is not zero); Figure 11 shows the lit state of the in-vehicle light strip when the vehicle is accelerating left (acceleration is not zero); Figure 12 shows the lit state of the in-vehicle light strip when the vehicle is decelerating left (acceleration is not zero); Figure 13 shows the lit state of the in-vehicle light strip when the vehicle is accelerating right (acceleration is not zero); Figure 14 shows the lit state of the in-vehicle light strip when the vehicle is decelerating right (acceleration is not zero).

[0149] The above Figures 8 to 14 In this, label 1 represents the direction indicator light, label 2 represents the acceleration amplitude indicator light, the left and right biases of the arrow represent the direction of the vehicle (going straight, turning left, and turning right), and the front and back orientations of the arrow represent the acceleration direction of the vehicle (operation, acceleration, and deceleration).

[0150] This application does not limit the lit color and lit brightness of the light beads. In practical applications, the lit color and lit brightness of the light beads can enable passengers to distinguish the direction indicator light and the acceleration amplitude indicator light, as well as the magnitude of the acceleration.

[0151] In some embodiments, during the vehicle's driving process, passengers do not necessarily always experience motion sickness. At this time, obtaining and analyzing the vehicle's driving state data will bring unnecessary energy consumption and system operation burden to the vehicle. However, performing the visual prompt method after passengers experience motion sickness can optimize the vehicle's resource usage.

[0152] Therefore, as Figure 15 shown, the above step S100 can also be specifically implemented as S101:

[0153] S101. When it is recognized that passengers experience motion sickness, obtain the vehicle's driving state data.

[0154] In some embodiments, by setting a device in the vehicle that can obtain the passenger state, it is automatically determined whether passengers experience motion sickness.

[0155] Exemplarily, when a passenger experiences motion sickness, their body posture often changes, leading to a change in the seat pressure distribution. At the same time, motion sickness may cause phenomena such as the passenger sweating. By setting pressure sensors and humidity sensors around the vehicle seat to detect whether these changes occur in the passenger, it is possible to determine whether the passenger is experiencing motion sickness.

[0156] Exemplarily, when a passenger experiences motion sickness, the passenger's facial expression may change, such as frowning, eyes closing tightly, sweating, etc. After the camera in the vehicle captures the facial image data of the passenger, the captured image is processed through computer vision technology or a detection model for identifying motion sickness phenomena, and then it is automatically determined whether the passenger is experiencing motion sickness.

[0157] In some embodiments, when a manual operation by the passenger is obtained, it is determined that the passenger is experiencing motion sickness.

[0158] Exemplarily, a button for feedback on motion sickness phenomena is set on the vehicle's control panel (such as the central control screen) or the passenger's personal device (a mobile phone connected to the vehicle system). When the passenger feels symptoms of motion sickness, such as dizziness, nausea and other discomfort, and presses this button, after the vehicle system receives this manual operation signal, it is determined that the passenger is experiencing motion sickness.
