Description

Technical Field

[0001] The present invention relates to the technical field of motion sickness, and in particular to a method and device for alleviating motion sickness based on sound interaction. Background Art

[0002] Motion sickness is a common discomfort symptom experienced by electric vehicle passengers during the ride, and the academic community has conducted extensive research on this. For autonomous or assisted driving vehicles, studies have shown that providing passengers with information about the upcoming vehicle motion status (within 1-3 seconds) can effectively reduce motion sickness symptoms. This information can be conveyed to passengers through multiple modalities such as vision, touch, and hearing. For example, warning of vehicle acceleration, deceleration, or lane changes through the flashing of LED lights in the car, sound signals in the cabin, or vibrations in the seats has been shown to significantly improve passengers' motion sickness experience. However, these multimodal information transmission methods usually require predictions of the vehicle's future motion behavior, so these solutions are not applicable to manually driven vehicles.

[0003] In addition, although academia and industry have explored a variety of motion sickness relief methods for manually driven vehicles, they mainly focus on visual solutions using mobile terminals. Specifically, these methods display the vehicle's motion status in real time through innovative interactive designs on mobile devices such as smartphones or tablets in order to relieve passengers' motion sickness. At present, multimodal interaction solutions (visual, auditory, and tactile) designed to relieve motion sickness usually rely on the prediction of the vehicle's future motion status. This dependence limits the scope of application of these solutions, which are mainly applicable to assisted driving or autonomous driving vehicles. However, manual driving scenarios are more common in reality, and the application of existing solutions in this scenario is limited. Although motion sickness relief solutions for manual driving scenarios have been explored, they mainly focus on visual interaction. These solutions usually require additional on-board displays or mobile terminal devices such as smartphones or tablets. However, the effective transmission of these visual information depends on the passengers using these devices. In actual driving, passengers may not receive this information because they close their eyes to rest, read, watch the scenery outside the window, or engage in other visual activities, resulting in limited practicality of visual interaction solutions. Summary of the invention

[0004] In view of the above-mentioned deficiencies in the prior art, the present invention provides a method and device for alleviating motion sickness based on sound interaction, which solves the problem that motion sickness is difficult to alleviate in manual driving scenarios.

[0005] In order to achieve the above-mentioned object of the invention, the technical solution adopted by the present invention is: a method for alleviating motion sickness based on sound interaction, comprising:

[0011] Furthermore, the expressions for the loudness of the vehicle kinetic energy recovery activation information and the loudness of the vehicle kinetic energy recovery completion information are both:

[0012]

[0013] Wherein, A represents the loudness of the vehicle kinetic energy recovery activation information and the loudness of the vehicle kinetic energy recovery completion information, and ax represents the vehicle acceleration.

[0020] The specific implementation modes of the present invention are described below so that those skilled in the art can understand the present invention. However, it should be clear that the present invention is not limited to the scope of the specific implementation modes. For those of ordinary skill in the art, as long as various changes are within the spirit and scope of the present invention as defined and determined by the attached claims, these changes are obvious, and all inventions and creations utilizing the concept of the present invention are protected.

[0021] Embodiment 1

[0022] Figure 1 FIG. 1 is an exemplary flow chart of a method for alleviating motion sickness based on sound interaction according to some embodiments of this specification. Figure 1 As shown, the process includes the following steps. In some embodiments, the process can be executed by a processor.

[0023] S1: Obtain the status of the vehicle kinetic energy recovery system by monitoring the vehicle kinetic energy recovery system.

[0024] The vehicle kinetic energy recovery system is a system used to recover the vehicle's kinetic energy.

[0025] The status of the vehicle recovery system includes an activated state and an inactivated state.

[0026] In some embodiments, the processor may obtain the status of the vehicle recycling system through vehicle system information provided by the manufacturer, and determine whether the vehicle recycling system is in an activated state.

[0027] S2: When the vehicle recovery system is in an activated state, the vehicle speed is monitored using an accelerometer to obtain vehicle speed change information.

[0028] The vehicle speed change information includes the acceleration state and the deceleration state.

[0029] In some embodiments, the processor may utilize an accelerometer to monitor the longitudinal speed change of the vehicle in real time and obtain vehicle speed change information.

[0030] In some embodiments, the processor can obtain vehicle speed change information through the vehicle system.

[0031] S3: When the vehicle speed change information is in a deceleration state, a vehicle kinetic energy recovery positive activation information is sent through a prompt sound; when the vehicle speed change information is in an acceleration state, a vehicle kinetic energy recovery end information is sent through a prompt sound, and motion sickness is relieved by using the prompt sound.

[0032] The vehicle kinetic energy recovery activation information is an audible message reflecting that the vehicle is decelerating.

[0033] In some embodiments, when the processor recognizes that the vehicle speed change information is a deceleration state, the processor can send a vehicle kinetic energy recovery positive activation message by broadcasting a prompt tone.

[0034] The prompt sound is a sound used to prompt the change of the vehicle's motion state. For example, the prompt sound may include a pulse wave, a sawtooth wave, a sine wave, a composite wave, etc.

[0035] In some embodiments, the reminder sound can be broadcasted through speakers installed around the vehicle. For example, the reminder sound can be broadcasted through a speaker installed in the front (center of the front driving platform), a speaker in the back (center of the rear trunk), a speaker on the left (near the left door handle of the rear row), and a speaker on the right (near the right door handle of the rear row).

[0036] In some embodiments, when the processor detects that the direction of the vehicle's longitudinal acceleration is rearward, it determines that the vehicle is decelerating, and a sound signal is sounded at the rear speaker to prompt the vehicle to move.

[0037] In some embodiments, the vehicle kinetic energy recovery positive activation information is a rectangular waveform of 0-1000 Hz, the loudness of the vehicle kinetic energy recovery positive activation information is proportional to the vehicle deceleration amplitude, and the duration is consistent with the vehicle deceleration time.

[0038] The vehicle's kinetic energy recovery has ended message is a sound message reflecting that the vehicle is accelerating.

[0039] In some embodiments, when the processor recognizes that the vehicle speed change information is an acceleration state, the processor can send a message that the vehicle kinetic energy recovery has ended by broadcasting a prompt tone.

[0040] In some embodiments, the vehicle kinetic energy recovery completion information is a triangular waveform of 2000-5000 Hz, the loudness of the vehicle kinetic energy recovery completion information is proportional to the vehicle acceleration intensity, and the duration is 1-5s.

[0041] In some embodiments, when the processor detects that the longitudinal acceleration direction of the vehicle is forward, it is determined that the vehicle is accelerating, and a sound signal is emitted from a front speaker to prompt the vehicle to move.

[0042] In some embodiments, the expressions for the loudness of the vehicle kinetic energy recovery activation information and the loudness of the vehicle kinetic energy recovery completion information can both be:

[0043]

[0044] Wherein, A represents the loudness of the vehicle kinetic energy recovery activation information and the loudness of the vehicle kinetic energy recovery completion information, and ax represents the vehicle acceleration.

[0045] In some embodiments, the prompt tone can be broadcast through two front speakers and two rear speakers.

[0046] In some embodiments, the vehicle kinetic energy recovery activation information can be broadcasted through the rear speaker, and the vehicle kinetic energy recovery end information can be broadcasted through the front speaker.

[0047] In some embodiments, the prompt tone can also send emergency braking information, emergency acceleration information, lane change information and turn information.

[0048] The emergency brake signal is an audible signal reflecting a sudden decrease in vehicle speed.

[0049] In some embodiments, when the processor detects that the longitudinal acceleration direction of the vehicle is rearward and the magnitude exceeds a threshold, it is determined that the vehicle brakes suddenly, and a corresponding sound signal is sounded at the rear speaker to prompt the vehicle to move.

[0050] The rapid acceleration information is an audible message reflecting a significant increase in vehicle speed.

[0051] In some embodiments, when the processor detects that the direction of the vehicle's longitudinal acceleration is forward and the magnitude exceeds a threshold, it is determined that the vehicle is accelerating rapidly, and a corresponding sound signal is sounded in the front speaker to prompt the vehicle to move.

[0052] Lane change information is sound information reflecting the vehicle changing its driving lane.

[0053] In some embodiments, the processor may utilize an accelerometer to monitor the lateral velocity changes of the vehicle in real time and obtain vehicle velocity change information.

[0054] In some embodiments, when the processor detects that the direction of the vehicle's lateral acceleration is to the left, it determines that the vehicle is changing lanes to the left, and a sound signal is emitted from the left speaker to prompt the vehicle to move.

[0055] In some embodiments, when the processor detects that the direction of the vehicle's lateral acceleration is to the right, it determines that the vehicle is changing lanes to the right, and a sound signal is sounded by the right speaker to prompt the vehicle to move.

[0056] Turning information is the sound information that reflects the amplitude of the curve in which the vehicle is running.

[0057] In some embodiments, when the processor detects that the lateral acceleration of the vehicle is right and the longitudinal acceleration of the vehicle is forward, it is determined that the vehicle is turning right or making a U-turn, and sound signals are emitted simultaneously from the right speaker and the front speaker.

[0058] In some embodiments, motion sickness can also be alleviated through interaction between prompt sounds and devices around the passenger.

[0059] Passenger peripheral devices are personal devices used to alert passengers to changes in vehicle motion. For example, passenger peripheral devices may include left and right wristbands, seats, and headrests, among which the seats can be slidably connected to the vehicle body, and the seats can adjust the forward and backward tilt ranges and the height of the left and right armrests.

[0060] In some embodiments, the processor can use the passenger's peripheral equipment to provide tactile feedback and broadcast the prompt sound. For example, when the vehicle changes lanes to the left, turns left, or makes a left U-turn, the left wristband vibrates; when the vehicle changes lanes to the right, turns right, or makes a right U-turn, the right wristband vibrates; wherein the intensity of the wristband vibration is proportional to the absolute value of the acceleration.

[0061] In some embodiments, the expression of the intensity of the bracelet vibration may be:

[0062] A = r × |a|;

[0063] Among them, A represents the intensity of the bracelet's vibration, r represents the vibration coefficient, and a represents the acceleration.

[0064] In some embodiments, the processor can adjust the degree of forward and backward tilt of the seat and the speed at which the seat moves forward and backward with the vehicle body according to the longitudinal acceleration of the vehicle.

[0065] In some embodiments, the processor may adjust the height of the left and right armrests of the seat accordingly according to the lateral acceleration of the vehicle.

[0066] In this way, the force exerted on passengers by the speed changes of electric vehicles during movement can be effectively counteracted, greatly alleviating the occurrence of motion sickness in passengers.

[0067] In some embodiments of this specification, motion sickness is alleviated by designing a prompt sound. (1) Through innovative interactive methods, the frequency and severity of motion sickness in passengers during kinetic energy recovery in electric vehicles are effectively reduced; (2) Through the intelligent association of sound signals with the vehicle's motion state, the passenger's perception of the vehicle's dynamics is significantly improved, thereby reducing the occurrence of motion sickness; (3) By improving the riding experience, it helps to increase the utilization rate and market share of electric vehicles and improve economic benefits; (4) By reducing the occurrence of motion sickness, the comfort and safety of passengers are improved, which helps to promote the popularization and sustainable development of electric vehicles; (5) By improving the riding experience of electric vehicles, more people are encouraged to choose electric vehicles as a means of transportation, thereby reducing dependence on fossil fuels and having a positive impact on environmental protection and energy conservation.
