The control unit 20 may provide a walking recommendation guidance function, a driving route providing function, and a parking lot guidance function to the vehicle depending on the amount of activity.

For example, the control unit 20 may compare the activity amount with a preset reference activity amount and provide a walking recommendation guidance function, a driving route provision function, and a parking lot guidance function to the vehicle. If the user's activity level is less than the preset activity level, the control unit 20 may output a voice signal recommending walking to increase the user's activity level. Alternatively, the control unit 20 may provide various changes to the driving route to increase the user's activity amount when the user's activity amount is less than the preset activity amount. Alternatively, the control unit 20 may provide a function to guide the parking lot to a point away from the destination so that the user's activity amount can be increased if the user's activity amount is less than the preset activity amount. That is, the control unit 20 may provide the above-described walking recommendation guidance function, driving route provision function, and parking lot guidance function to the vehicle so that the difference between the user's activity amount and the preset activity amount is minimized (S502, 505) ).

Alternatively, the control unit 20 may compare the activity amount with the past average activity amount and provide a walking recommendation guidance function, a driving route provision function, and a parking lot guidance function to the vehicle. If the user's activity level is lower than the past average activity level, the control unit 20 may output a voice signal recommending walking to increase the user's activity level. Alternatively, the control unit 20 may provide various changes to the driving route to increase the user's activity amount when the user's activity amount is lower than the past average activity amount. Alternatively, the control unit 20 may provide a function to guide the parking lot to a point away from the destination so that the user's activity level can be increased if the user's activity level is lower than the past average activity level. That is, the control unit 20 may provide the above-described walking recommendation guidance function, driving route provision function, and parking lot guidance function to the vehicle so that the difference between the user's activity amount and the past average activity amount is minimized (S503, 505 ).

If the user's activity level is lower than the average activity level of a similar group, the control unit 20 may output a voice signal recommending walking to increase the user's activity level. Alternatively, if the user's activity level is lower than the average activity level of a similar group, the control unit 20 may provide various changes to the driving route to increase the user's activity level.

That is, the control unit 20 may provide the above-described walking recommendation guidance function, driving route provision function, and parking lot guidance function to the vehicle so that the difference between the user's activity amount and the average activity amount of similar groups is minimized (S504 , 505).

Figure 6 is a diagram for explaining the operation of a health care system for vehicle drivers according to an embodiment.

Referring to Figure 6, the control unit 20 can determine the user's sleeping state using information collected from the camera 13, radar 14, and microphone 15.

In an embodiment, the camera 13 captures the user's sleeping situation, and the controller 20 analyzes this to determine the user's sleeping state through analysis of the user's movements in the sleeping state. In addition, the radar 14 detects the user in a sleeping state, and the control unit 20 analyzes this to determine the user's sleeping state through analysis of the user's movements in the sleeping state. In addition, the microphone 15 detects the user's voice signal or environmental noise generated in the sleeping state, and the control unit 20 analyzes the user's voice signal and environmental noise in the sleeping state to determine the user's sleeping state. You can judge. Through this, the control unit can comprehensively analyze the user's breathing rate, breathing sound, body movement degree, body movement sound, etc. to classify the sleep state into stages (S601).

If the sleep state is lower than the average sleep state stored in the database, the controller 20 may provide a driving route that passes through a rest area or drowsiness rest area. The control unit 20 divides the user's sleep state into a plurality of grades, compares the classified grades with a preset average sleep state, and, if the grade is determined to be lower than the average sleep state, determines a driving route that passes through a rest area or drowsiness rest area. Can be provided (S602).

Additionally, the controller 20 may control the operation of the autonomous driving assistance function depending on the sleep state.

For example, the controller 20 may set a different driving route by comparing the sleep state with the average sleep state stored in the database. The control unit 20 may set the driving route differently depending on the difference between the level of the user's sleep state and the average sleep state. For example, if the user's sleep state grade falls three levels or lower than the average sleep state grade, the control unit 20 may determine that driving is impossible and recommend autonomous driving. If the user does not use autonomous driving, the control unit automatically turns on advanced driver assistance system functions such as forward collision-avoidance assist, rear collision-avoidance assist, lane keeping assist, smart cruise control, and highway driving assist. Can be controlled (S603~604).

Alternatively, the control unit 20 may determine that highway driving is not possible if the user's sleep state grade falls two levels or lower than the average sleep state grade and provide a driving route through city driving or national highway driving (S605) ~606).

Alternatively, the control unit 20 may provide a driving route to pass through a rest area or drowsiness rest area when the user's sleep state grade falls one level or lower than the average sleep state grade (S60607-608).

Alternatively, the controller 20 may control at least one of lighting, air conditioning, vehicle seats, and AVN inside the vehicle according to the sleeping state. The control unit 20 controls the illuminance of the vehicle interior lighting, the intensity of the air conditioning system, the tilt of the vehicle seat, and the guidance function of the AVN according to the difference between the level of the user's sleep state and the average sleep state to prevent the user from drowsy driving. You can encourage them not to do it. For example, the controller may use a mood lamp inside the vehicle to adjust the color to a high illuminance level to prevent drowsiness, and may control the lavender scent placed in the air conditioning device to be radiated into the vehicle interior. Additionally, the controller can control AVN to reproduce sound sources in a frequency band that prevents the driver from drowsiness (S609).

Figure 7 is a diagram for explaining the operation of a health care system for vehicle drivers according to an embodiment.

Referring to Figure 7, the control unit 20 can collect blood sugar and pulse rate from the optical sensor 16 and determine the user's biosignals using the collected information. As the pulse wave propagates as a pulsating wave due to heart contraction and relaxation, changes in blood vessel volume occur. Photoplethysmograph (hereinafter referred to as “PPG”) is a method of measuring pulse waves using light. Changes in optical properties such as reflection, absorption and transmission ratio of biological tissue that occur when the volume of blood vessels change are detected by an optical sensor. Detect and measure. Unlike an electrocardiogram, it measures changes in blood flow delivered to peripheral blood vessels, but pulse waves can be easily measured by applying optical sensors to fingers, forehead, earlobes, etc., rather than using electrocardiogram electrodes.

For example, the control unit 20 may externally output a notification signal that induces the user to measure blood sugar and pulse rate before boarding the vehicle. When the smart key approaches the vehicle or the vehicle door is unlocked, the control unit 20 outputs a voice signal or a vibration signal to induce measurement of the user's blood sugar and pulse, and uses the optical sensor 16 to measure blood sugar and pulse. The pulse rate can be collected and the user's biological signals can be determined using the collected information (S701~702)

The control unit 20 may provide a driving route via a hospital when blood sugar and pulse rate are outside a preset standard range. If the user's blood sugar and pulse rate exceed preset normal standards, the control unit 20 may provide a driving route to pass through a hospital located between the current location and the destination (S703-704).

Alternatively, the control unit 20 may control at least one of lighting, air conditioning, vehicle seats, and AVN inside the vehicle according to the biosignal determination result. The control unit 20 controls the illuminance of the vehicle interior lighting, the intensity of the air conditioning system, the tilt of the vehicle seat, and the guidance function of the AVN according to the results of determining the user's biological signals to ensure that the user's autonomic nervous system is in an optimal state. And through this, the user's body can be induced to maintain homeostasis. For example, the control unit can adjust the lighting color to purple using a mood lamp inside the vehicle and control the aroma disposed in the air conditioning device to be radiated into the vehicle interior. Additionally, the control unit can control AVN to reproduce sound sources (natural sounds, white noise, etc.) in a frequency band that allows the driver's psychological state to remain normal (S705).

Additionally, if it is determined that an accident has occurred in the vehicle being driven, the control unit 20 may transmit the most recently collected blood sugar and pulse rate to the hospital (S706-707).
