Description
[Technical Field]
[0001] This invention relates to an auxiliary system, and more particularly to a vehicle auxiliary system with physiological discrimination. [Previous Technology]
[0002] As society gradually ages, the threat to road safety posed by elderly drivers is increasing due to factors such as poor physical health and declining spatial judgment and cognitive function. Therefore, the safety of elderly drivers is a topic of concern for many people in the field of autonomous driving or assisted driving.
[0003] However, existing vehicle assistance systems with physiological discrimination mainly assist drivers in correcting vehicle malfunctions or judging traffic lights and road markings to avoid driving errors and improve driving safety by detecting abnormal driving conditions and abnormal physiological information of the driver during driving. However, existing vehicle assistance systems cannot adjust the original vehicle's driving assistance functions according to different drivers. As a result, if the driver is, for example, an elderly person, the driving assistance functions provided by the original vehicle are quite limited in their help to elderly drivers and are difficult to assist elderly drivers in driving safely and easily.
[0004] Therefore, how to solve the problems of the prior art is the main focus of the present invention. [Summary of the Invention]

The processing device compares the time required for it to generate the test signal output to receive the second pressure sensing signal with a preset reaction time to obtain the reaction ability indicating whether the driver's reaction is fast or slow.

Implementation Method
[0017] The present invention will be described in detail through the following embodiments and accompanying drawings, so as to help those skilled in the art to understand the purpose, features and effects of the present invention. It should be noted that in the following description and claims, the terms "comprising" and "including" are used in an open-ended manner and should not be construed as closed terms such as "consisting of". Additionally, the term "coupled" is intended to indicate indirect or direct coupling. Therefore, if one device is coupled to another device, this connection can be direct coupling or indirect coupling via other devices and connections. Furthermore, in the following description and claims, terms such as "first," "second," and "third" are used to distinguish between elements, rather than to limit the elements themselves or indicate a specific order of elements.
[0018] Referring to Figures 1 and 2, an embodiment of the vehicle assistance system 1 with physiological identification of the present invention is described. The vehicle assistance system 1 is applicable to a vehicle (not shown) and includes a playback device 10, a sensing device 11, a processing device 12, a driving assistance device 13, a physiological sensing device 14, and a plurality of light emitters 15, 16.
[0019] The playback device 10 receives a test signal output and accordingly plays an output signal indicating a test command output to a driver who has just started the vehicle. In this embodiment, the playback device 10 is an audio playback device, such as an in-vehicle speaker, and the output signal is a voice output signal, but is not limited thereto. In other embodiments, the playback device 10 is a media player that can be used to play voice signals and / or video signals.
[0020] The sensing device 11 senses the driver's response actions based on the output signal to generate a sensing signal output for judging the driver's (before driving) physiological condition, thereby testing the driver's vision, focus, reaction and control abilities, etc. In this embodiment, the sensing device 11 is installed on a steering wheel 100 or a brake pedal (not shown) of the vehicle.
[0021] The processing device 12 is coupled to the playback device 10, the sensing device 11, and the light emitters 15 and 16. Before the driver starts the vehicle and drives, when the processing device 12 receives personal information input by the driver (e.g., the driver's name, gender, age, etc.) through a user input interface 17, the processing device 12 first records the personal information, and then enters a physiological condition test. At this time, the processing device 12 generates the test signal output and transmits it to the playback device 10. Then it receives the sensing signal output from the sensing device 11, and at least determines whether to generate an assistance judgment result indicating a driving assistance need based on the sensing signal output. At the same time, the processing device 12 generates multiple light emission control signals and outputs them to the light emitters 15 and 16 respectively, so that the light emitters 15 and 16 respectively receive the light emission control signals and respectively emit light or not emit light and adjust their light emission color according to the light emission control signals. In this embodiment, the processing device 12 may be, for example, a central processing unit (CPU) or a microprocessor, specifically composed of programmable integrated circuits. The light emitters 15 and 16 are mounted on the upper half of the steering wheel 100 of the vehicle, and each is a light-emitting diode (LED) device capable of emitting red, green, or blue light. This description uses two light emitters as an example, but is not limited to this; the upper half (or lower half, or the entire ring) of the steering wheel 100 may be equipped with two or more light emitters.
[0022] The driving assistance device 13 is coupled to the processing device 12, and upon receiving the assistance determination result, generates a corresponding driving assistance function based on the assistance determination result during the driver's driving. In this embodiment, the driving assistance device 13 may be, for example, a microcontroller unit (MCU), a programmable logic controller (PLC), a system-on-chip (SoC), a field-programmable gate array (FPGA), an application-specific integrated circuit (ASIC), or other similar devices or combinations thereof. The driving assistance device 13 is electrically connected to an electronic control unit (ECU, not shown) of the vehicle, enabling the driving assistance device 13 to adjust the vehicle's driving assistance coefficients through the ECU to generate corresponding driving assistance functions, such as amplification, increased / decreased steering wheel turning force, increased / decreased braking force, and traffic light prompts. It should be noted that how the driving assistance device 13 adjusts the driving assistance coefficient of the vehicle through the electronic control unit to generate the corresponding driving assistance function is well known to those skilled in the art, and will not be elaborated here for the sake of brevity.
[0023] The physiological sensing device 14 is coupled to the processing device 12 and is used to sense the driver's physiological information (e.g., heart rate or blood pressure) during a physiological condition test (i.e., before the driver starts the vehicle and drives), to generate a physiological information sensing result and output it to the processing device 12. When the processing device 12 determines that a sensing value of the physiological information sensing result is greater than a preset value (i.e., the physiological information is abnormal), it determines that the driver is not suitable for driving, and the processing device 12 generates a warning message to the vehicle to alert the driver to change drivers or issue a valet driver request signal. In this embodiment, the processing device 12 transmits the warning information to the playback device 10 to emit a warning sound, or to a display device (not shown, for example, a head-up display, HUD) in the vehicle to display it on a screen. The physiological sensing device 14 can be installed anywhere in the vehicle that can sense the driver's physiological information, and is, for example, an electrocardiogram (ECG) sensor or a photoplethysmography (PPG) sensor, but is not limited thereto.
[0024] The following describes in more detail the operation of the vehicle assistance system 1 in conducting a physiological condition test on the driver during the physiological condition test. After the driver's physiological function test is completed, the driving assistance device 13 will adjust the driving assistance function of the vehicle by changing the driving assistance coefficient of the vehicle through the electronic control unit according to the test results (i.e., the assistance judgment results) to improve the driver's driving endurance and make the driving process safer and easier.
[0025] The sensing device 11 includes a first pressure sensor 111, a plurality of second pressure sensors 112 and 113, at least one third pressure sensor, and a fourth pressure sensor 116. In this embodiment, the at least one third pressure sensor is exemplified by two third pressure sensors 114 and 115, but it is not limited thereto. In other embodiments, the number of third pressure sensors may be one or more than two. Furthermore, the number of the second pressure sensors is also exemplified by two, but it is not limited thereto. In other embodiments, the number of the second pressure sensors may be more than two. The first pressure sensor 111, the second pressure sensors 112 and 113, and the third pressure sensors 114 and 115 are mounted on the steering wheel 100 of the vehicle, but are not limited thereto. The fourth pressure sensor 116 is mounted on the brake pedal of the vehicle. It should be noted that in other embodiments, the first pressure sensor 111 may also be part of the third pressure sensor 114 (115) or the second pressure sensor 112 (113), the second pressure sensor 112 (113) may also be part of the third pressure sensor 114 (115) or the first pressure sensor 111, or the third pressure sensor 114 (115) may also be the first pressure sensor 111 or the second pressure sensor 112 (113), thus reducing the number of pressure sensors required for the sensing device 11. In this embodiment, the sensing signal output includes a first pressure sensing signal, a second pressure sensing signal, two third pressure sensing signals (i.e., at least one third pressure sensing signal, the number of which corresponds to the number of the at least one third pressure sensor), and a fourth pressure sensing signal. The test instruction output in the output signal played by the playback device 10 includes, but is not limited to, a first press test instruction related to a hearing test, a second press test instruction indicating a light color to be pressed, a third press test instruction related to a muscle strength test, and a foot press test instruction related to a control accuracy test.
[0026] The first pressure sensor 111 is coupled to the processing device 12 and is used to sense the pressure made by the driver according to the first press test command indicated by the output signal (e.g., the volume of the output signal gradually decreases from loud to silent) (e.g., instructing the driver to press the first pressure sensor 111 on the steering wheel 100 when he hears a sound until he can no longer hear a sound), so as to generate the first pressure sensing signal and output it to the processing device 12, so that the processing device 12 determines whether to generate the auxiliary discrimination result based on the first pressure sensing signal. In this embodiment, when the processing device 12 determines that the duration of receiving the first pressure sensing signal is less than a preset time (i.e., the driver has hearing impairment or poor hearing sensitivity), the processing device 12 generates the auxiliary discrimination result. The auxiliary discrimination result indicates that the driving assistance requirement is a sound amplification requirement, and the driving assistance function is a sound amplification function. Subsequently, the driving assistance device 13 controls the sound amplification function or the degree of shielding of external vehicle sounds by controlling the relevant sound receiving and amplification components installed in the vehicle through the electronic control unit during the driver's driving, based on the auxiliary discrimination result. When the processing device 12 determines that the duration of receiving the first pressure sensing signal is greater than or equal to the preset time, the processing device 12 does not generate the auxiliary discrimination result, but is not limited to this.
[0027] The second pressure sensors 112 and 113 are respectively provided corresponding to the light emitters 15 and 16, and the second pressure sensors 112 and 113 are coupled to the processing device 12 to sense the pressure made by the driver according to the second press test command indicated by the output signal (e.g., indicating pressing an area or button with a light emission color (such as red light)), so as to generate the second pressure sensing signal and transmit it to the processing device 12, so that the processing device 12 can determine which light emitter is pressed based on the second pressure sensing signal. The second pressure sensor emits the second pressure sensing signal (for example, it is known that the second pressure sensor 112 emitted the second pressure sensing signal), and based on the light emission control signal output by itself to the light emitter (15) corresponding to the second pressure sensor (112) that emitted the second pressure sensing signal, it determines whether the light emitter (15) corresponding to the second pressure sensor (112) emits the light color (i.e., whether the light emitter (15) emits red light), so as to determine whether to generate the auxiliary discrimination result. It should be noted that the second pressure sensing signal has an identification code of the corresponding second pressure sensor, so that the processing device 12 can know which second pressure sensor it comes from based on the second pressure sensing signal. In this embodiment, when the emitter (15) corresponding to the second pressure sensor (112) that emits the second pressure sensing signal does not emit the specified color (i.e., the driver touches the wrong object, indicating that the driver's color perception ability is abnormal), the processing device 12 generates the auxiliary judgment result. The driving assistance requirement indicated by the auxiliary judgment result is a traffic light warning requirement, and the driving assistance function is a traffic light warning function. Furthermore, when the emitter (15) corresponding to the second pressure sensor (112) that emits the second pressure sensing signal does emit the specified color, the processing device 12 also determines the driver's reaction ability to decide whether to generate the auxiliary judgment result. The processing device 12 compares the time required to generate the test signal and receive the second pressure sensing signal with a preset reaction time to obtain the driver's reaction ability, indicating whether the driver's reaction is fast or slow. When the reaction ability indicates that the driver's reaction is slow (i.e., the driver's reaction ability is abnormal, and the required time is greater than the preset reaction time), the processing device 12 generates the auxiliary judgment result. The driving assistance requirement indicated by the auxiliary judgment result is a distance-to-reaction distance adjustment requirement, and the driving assistance function is a distance-to-reaction distance adjustment function. It should be noted that when the test result shows that the driver's color perception ability and reaction ability are normal, the processing device 12 does not generate the auxiliary judgment result.
[0028] Referring further to Figure 3, for example, at the start of the test, the output signal instructs the driver to place both hands on the third pressure sensors 114 and 115 on the steering wheel 100, and then look at the area of the light emitters 15 and 16 on the steering wheel 100. During the color perception test and reaction time test, the light emitters 15 and 16 emit green and red light respectively. The processing device 12 generates the test signal output and records the current time. The output signal instructs the driver to touch the red light (or the green light, or touch the red light and green light in sequence). When the driver touches the wrong object (i.e., the processing device 12 determines, based on the second pressure sensing signal and the corresponding light emission control signal, that the emitter (15) is not emitting red light), it indicates that the driver's color perception ability is abnormal. Subsequently, the driving assistance device 13 will, based on the assistance judgment result, control a front camera (not shown) and a display device (not shown) of the vehicle through the electronic control unit to activate the traffic light prompt function while the driver is driving, so that the driver can obtain the text prompt function of the traffic light from an augmented reality (AR) screen 101 on the display device (see Figure 3). In this embodiment, the AR screen 101 is formed on the upper left of the windshield 102 of the vehicle. The display device is, for example, a head-up display (HUD) to reflect traffic light information or vehicle driving information onto the windshield 102 to form a head-up display effect, but is not limited to this. When the driver touches the correct light (i.e., color perception is normal), the processing device 12 compares the time required from generating the test signal output (corresponding to the voice instruction for the driver to touch the red light) to receiving the second pressure sensing signal with the preset reaction time to obtain the driver's reaction ability. When the reaction ability indicates that the driver's reaction is slow, the driving assistance device 13 will subsequently adjust the vehicle's distance from surrounding vehicles through the electronic control unit based on the assistance judgment result during the driver's driving, thereby making the driving process safer.
[0029] It should be noted that in other embodiments, the reaction ability test does not need to be operated after the color perception ability is normal, that is, the reaction ability test can be operated independently. For example, during the reaction ability test, the output signal instructs the driver to quickly touch the area of the light emitter that emits the indicated color according to the voice prompt. For example, if the voice prompt is to touch the green light with the right hand, the driver will immediately raise his right hand and touch the area corresponding to the light emitter (15). The processing device 12 will record the time required from the generation of the test signal output (corresponding to the voice prompt to touch the green light with the right hand) to the receipt of the second pressure sensing signal (i.e., the light emitter (15) is touched), and compare the required time with the preset reaction time to obtain the driver's reaction ability.
[0030] The third pressure sensors 114 and 115 are coupled to the processing device 12 and are used to sense the pressure made by the driver according to the third press test command indicated by the output signal (for example, instructing the driver to grip the steering wheel 100 with both hands on the third pressure sensors 114 and 115), so as to generate the third pressure sensing signals and transmit them to the processing device 12, so that the processing device 12 determines whether to generate the auxiliary discrimination result based on the third pressure sensing signals. In this embodiment, when the processing device 12 determines that the total pressure value of the third pressure sensing signals is less than a preset pressure value, or determines that the duration of receiving the third pressure sensing signals is less than a preset time (i.e., indicating that the driver's hand muscle (endurance) is insufficient), the processing device 12 generates the auxiliary judgment result, and the driving assistance requirement indicated by the auxiliary judgment result is a steering wheel turning assistance requirement, and the driving assistance function is a steering wheel turning assistance function. Subsequently, the driving assistance device 13 controls the vehicle through the electronic control unit to adjust the increase of the steering wheel 100 turning power according to the auxiliary judgment result during the driver's driving. In this way, the driver can turn the steering wheel 100 more easily, thereby improving the driver's driving endurance and making the driving process safer. In this embodiment, when the processing device 12 determines that the total pressure value of the third pressure sensing signals is greater than or equal to the preset pressure value, or determines that the duration of receiving the third pressure sensing signals is greater than or equal to the preset time (i.e., indicating that the driver's hand muscle (endurance) is sufficient), the processing device 12 does not generate the auxiliary discrimination result, but is not limited thereto.
[0031] The fourth pressure sensor 116 is coupled to the processing device 12 and is used to sense the driver's pedaling according to the pedaling test command indicated by the output signal (e.g., instructing the driver to lightly, moderately, heavily, or continuously press the brake pedal), so as to generate the fourth pressure sensing signal and transmit it to the processing device 12, so that the processing device 12 determines whether to generate the auxiliary discrimination result based on the fourth pressure sensing signal. In this embodiment, when the processing device 12 determines that a pressure value of the fourth pressure sensing signal is less than a preset pedal pressure value (i.e., indicating poor brake control accuracy of the driver), the processing device 12 generates the auxiliary judgment result, and the driving assistance requirement indicated by the auxiliary judgment result is an increase in braking force, and the driving assistance function is a brake assist function; when the processing device 12 determines that the pressure value of the fourth pressure sensing signal is greater than the preset pedal pressure value (i.e., indicating poor brake control accuracy of the driver), the processing device 12 generates the auxiliary judgment result, and the driving assistance requirement indicated by the auxiliary judgment result is a decrease in braking force, and the driving assistance function is the brake assist function. Subsequently, the driving assistance device 13 controls the vehicle to adjust the increase or decrease of braking force through the electronic control unit during the driver's driving based on the auxiliary judgment result, thereby making the driving process safer. In this embodiment, when the processing device 12 determines that the pressure value of the fourth pressure sensing signal is equal to the preset pedal pressure value (that is, it indicates that the driver's brake control accuracy is good), the processing device 12 does not generate the auxiliary discrimination result.
[0032] As can be seen from the above description, the feature of the present invention is that the vehicle assistance system 1 can be used to adjust the driving assistance function of the vehicle according to the differences of the driver. In this way, the vehicle can be controlled more safely for different drivers, and the driver can be assisted to improve their driving endurance, so as to make the driving process safer and easier.
