This data includes, for example, whether or not a person gets sick, a symptom of a previous sickness (change in physical condition, an aura), a route that caused a sickness in the past, and a ride when the sickness occurred in the past. The type of vehicle (sedan, minivan, sports car, RV car), the driving situation (speed, steering angle, route, etc.) in the event of a motor sickness in the past, the route you do not want to travel, the route you want to travel, etc. It is remembered. This data is constantly updated by accumulating information transmitted from the automobile 6 regarding the sickness of the occupant and the running conditions (vehicle type, running route, etc.) when the sickness occurs. It is configured as follows.
[0024]
Further, the vehicle characteristic correction data 60 includes a correction value for correcting vehicle characteristics (steering steering sensitivity, brake braking performance, and suspension damping force) that cause a vehicle sickness or a high possibility of causing a vehicle sickness. Threshold values and the like are stored for each vehicle type. Further, the vehicle characteristic correction data 60 does not relate to a specific occupant, but generally includes data relating to driving conditions, vehicle characteristics, and the like, which are likely to cause motion sickness.
[0025]
As shown in FIG. 4, between the information center 2 and the individual's home 10 (including the portable information device 8), occupant sickness-related data is registered from the home 10 to the information center 2. For example, as a route that the user does not want to travel and a route that the user wants to travel, a route that has been traveled in the past and has a motor sickness, and a route that has not caused the motor sickness are registered, respectively. On the other hand, the information center 2 provides a virtual route to the input destination in advance to the individual's home 10 or the like.
Also, from the automobile 6 (mobile navigation device 20) to the information center 2, occupant information on who is riding, physical condition information on the physical condition of the occupant (vehicle sickness), current position and vehicle information (driving conditions, vehicle characteristics) Etc. are sequentially transmitted.
[0026]
On the other hand, from the information center 2 to the automobile 6 (mobile navigation device 20), the input route information to the destination, the corrected route information corrected in consideration of the motion sickness, the motion sickness information regarding the occupant's motion sickness, The threshold information and the like relating to the threshold value for vehicle sickness are transmitted.
[0027]
Further, when the occupant of the occupant in the car 6 is very drunk, the diagnosis reservation and the estimated arrival time of the occupant are transmitted from the information center 2 to the medical institution (hospital) 16. Further, information such as whether or not an occupant having a motor sickness is accepted at the medical institution is transmitted from the medical institution (hospital) 16 to the information center 2.
Next, the transmission and reception of information between the vehicle (mobile navigation device), the information center, and the medical institution / home in the vehicle motion sickness prevention system according to the present embodiment will be described with reference to FIG. FIG. 5 is a flowchart showing a process in the vehicle motion sickness prevention system. In the flowchart of FIG. 5, S indicates each step.
[0028]
As shown in FIG. 5, in S1, personal data related to the sickness of the occupant is transmitted from the PDA 8, the home 10, or the car 6 to the information center (sickness prevention server) 2, and this data is transmitted to the occupant's sickness. The initial value of the motion sickness-related data is registered in the occupant-specific motion sickness-related data 58 in association with the occupant (S2).
The motion sickness-related data includes, for example, presence / absence of motion sickness, a route that has not been driven, a route that has been set in advance, conditions in the event of a motion sickness in the past, and a vehicle type that frequently gets on the vehicle (sedan, minivan, Sports cars, RV vehicles, etc.). The presence or absence of motor sickness is whether or not the motor sickness has occurred in the past. As a route that the user does not want to travel, a route that the user does not want to travel is selected because he / she gets sick in the past. As the route set in advance, a route to be driven is selected because, for example, the vehicle was able to run without getting sick in the past.
[0029]
The conditions at the time of vehicle sickness are various conditions at the time when the occupant gets sick, and the vehicle type (sedan, minivan, sports car, RV vehicle, etc.) on which the occupant is riding, and the driving environment conditions (destination, route, etc.) ), Physical condition, physical condition reference value (normal pulse, blood pressure, etc.), physical condition change value during motor sickness, and vehicle interior conditions (odor, temperature, etc.). Based on these conditions, conditions (or vehicle sickness conditions) at which the occupant is likely to get sick are determined.
[0030]
Next, in the automobile 6, the occupant is specified in S3, and the occupant specific information is transmitted to the information center 2. The specification of the occupant may be performed by the occupant or the driver manually operating the mobile navigation device 20, or may be performed by the mobile navigation device 20 automatically.
The information center 2 retrieves and extracts the sickness-related data of the occupant in the automobile 6 from the sickness-related data 58 for each occupant in response to the specific information of the occupant. The data is transmitted to the device 20 (S4).
[0031]
Next, in S5, in S5, the characteristics of the vehicle are changed based on the received motion sickness-related data so that the occupant in the vehicle is less likely to suffer from motion sickness. Specifically, the characteristics of the power steering, the suspension, the engine, the temperature setting in the passenger compartment, the ventilation state, and the like are changed by an instruction from the CPU 22 of the mobile navigation device 20, for example. The change of the characteristic may be a change to the vehicle characteristic that generally makes it difficult to cause the motion sickness, instead of the received motion sickness-related data.
[0032]
Next, in S6, when the route proposal to the destination input to the mobile navigation device 20 is input and determined in advance in S1 or the like, this route is set as a route to the destination.
Next, in S7, a plurality of routes to the destination input by the user are set, and a screen displaying a plurality of route candidates to the destination, for example, as shown in FIG. 28, and the user (driver or occupant) selects a route.
[0033]
On this screen, in addition to the route on the map, the travel distance (65 km, 90 km, 130 km) and the required time (2 hours, 1.5 hours) for each route candidate (A route, B route, C route) , 1.2 hours), and the car with the probability of motion sickness (60%, 90%, 15%), and the length of the attention section (5 km, 25 km, 0 km) on the route where the motion sickness is likely to occur Car sickness information related to sickness is displayed. This attention section may be displayed by changing the color on the map.
[0034]
Furthermore, when the occupant with a motor sickness has been traveling on the route of this route candidate in the past, and the data on the motion sickness at that time is recorded, the route B is used as the past evaluation in the past. A display may be added such as a message indicating that car sickness occurred at a rate of 90% when the driver passed the car, and that no car sickness occurred (0%) during the route C. Based on such motion sickness information, the user can manually select a route (for example, route A) from route candidates in consideration of the risk of motion sickness, distance, required time, and cost. The process of S7 may be performed by the CPU 22 of the mobile navigation device 20 or may be performed by the information center 2.
[0035]
Further, the present invention is not a configuration in which the user selects a route as described above, but a route is set by the mobile navigation device or the information center 2, and the route is set when it is confirmed that a sick person gets on the vehicle. A configuration may be used in which the route that has been set is automatically corrected (changed) to a route that is less likely to cause motion sickness, based on the data on the occurrence of motion sickness for each road included in the road data 52. For example, in a configuration having a mode in which a shortest route is automatically set when a destination is set. A configuration in which the route is changed to a route where sickness does not easily occur may be used.
[0036]
Furthermore, when it is confirmed that an occupant with a motor sickness is riding, information on a driving method for avoiding a motor sickness (avoidance conditions), information on a resting place on a route to a destination (driving environment conditions), and the like are included. The information may be provided to the user (driver or occupant) by voice or display.
[0037]
Memorize and analyze the running condition etc. when the occupant who has a motor sickness in the past, based on the analysis result, calculate the probability of the sickness, caution section, etc., change the route, A configuration for creating and providing information for avoiding sickness may be used. For example, if past data shows that an occupant who gets sick while riding is likely to get sick when driving at a curve with a specific curvature at a certain speed, he may change the route to avoid such a curve. Alternatively, such a curve having a curvature may be displayed so as to drive at a speed that does not cause motion sickness.
[0038]
When traveling to the destination is started, the traveling state is determined in S8. In this determination, when a driving state that is likely to cause motion sickness is detected, a warning is issued to the driver by voice or display, and the driver is urged to perform driving that is less likely to cause motion sickness. For example, when a sudden braking, a sudden start, or a continuation thereof is detected, such an alarm is issued. The warning is performed as a warning by text on the display 28 or a warning by voice from a speaker. The driving condition that is likely to cause motion sickness may be the driving condition that is generally considered to be prone to motion sickness included in the occupant-specific motion sickness-related data 58, or the occupant that causes car sickness while riding may have actually Any of the driving states that cause motion sickness may be adopted. The latter provides more custom-made fine-grained control.
[0039]
In addition to such an alarm, correction control for changing the characteristics of the vehicle (steering steering sensitivity, brake braking performance, suspension damping force) to characteristics that do not cause motion sickness based on the vehicle characteristic correction data 60 may be performed. good. This correction control is performed by the information center 2 determining the content of the correction control and transmitting the correction content to the mobile navigation device 20 of the automobile 6.
[0040]
The content of the correction control for changing the vehicle characteristics includes the vehicle characteristics of the vehicle that the occupant who gets sick while riding has had a sickness in the past, the driving state at that time, the running state, and the current occupant. It may be determined according to the driving state of the running vehicle. That is, considering the difference between the characteristics (vehicle type) of the vehicle that was on board when the driver was sick in the past and the characteristics (vehicle type) of the vehicle currently on board, the vehicle currently on board It is preferable that the control contents of the vehicle characteristic of the vehicle be changed.
[0041]
Also, if the vehicle sick is familiar with a sports car, and the vehicle currently in use is a minivan, for example, increasing the damping force of the suspension, increasing the steering sensitivity, Control may be performed such as by reducing the power to bring the vehicle characteristics of the minivan in the vehicle close to the vehicle characteristics of a familiar sports car, and to reduce the likelihood of motor sickness.
[0042]
Furthermore, the configuration of changing the vehicle characteristics may be changed according to the boarding position (for example, front seat or rear seat) of an occupant who gets sick. This is because the state of occurrence of motion sickness varies considerably depending on the riding position.
Further, in S9, it is determined based on the detection of the motion sickness detection device 40 whether or not the motion sickness is occurring. When there is a possibility that a plurality of occupants may get sick, this determination is preferably performed for each occupant.
[0043]
Car sickness is comprehensively determined from detected values such as heart rate. Since the degree of motion sickness is considerably advanced when the person notices that he / she has a motor sickness, in the present embodiment, the person himself / herself detects a sign of motor sickness that cannot be recognized as having a motor sickness, and recognizes this as a sign of motor sickness. Is determined.
[0044]
In S9, when it is determined that the motor sickness has not occurred, the process returns to S8, and the processing of observing the state of the occupant is continued. When it is determined that the motor sickness is present, the process proceeds to S10, and control for preventing the symptoms of the motor sickness from becoming apparent (motor sickness correction) is performed. Specifically, the route to the destination is changed to a route that is less likely to cause motion sickness, the characteristics of the vehicle are changed to characteristics that are less likely to cause motion sickness, the rest facility and the route to the rest facility are displayed on the display (Figure 7) to encourage them to take a break. In correcting the motion sickness, it is preferable to refer to the data on the past motion sickness of the occupant having the motion sickness.
[0045]
The content of the correction control for changing the vehicle characteristics includes the vehicle characteristics of the vehicle that the occupant who gets sick while riding has had a sickness in the past, the driving state at that time, the running state, and the current occupant. It may be determined according to the driving state of the running vehicle. That is, considering the difference between the characteristics (vehicle type) of the vehicle that was on board when the driver was sick in the past and the characteristics (vehicle type) of the vehicle currently on board, the vehicle currently on board It is preferable that the control contents of the vehicle characteristic of the vehicle be changed.
Further, proceeding to S11, the degree of motor sickness is determined in the information center 2, and when the degree of motor sickness is higher than a predetermined level, the search for the medical institution 16, the notification to the medical institution, the notification to the medical institution and the Route guidance to a medical institution is performed.
[0046]
Further, in this embodiment, as shown in FIG. 8, it is determined whether or not the vehicle is in a predetermined traveling state (T1). A process (T2) of prohibiting all control for changing the vehicle characteristics and returning the characteristics of the vehicle to the initial state, that is, the original characteristics of the vehicle. The predetermined traveling state is a condition in which the traveling performance of the vehicle should be prioritized, and indicates, for example, a time of a sharp turn, a time of a rapid braking, and a time of a low μ road. Under such conditions, the running of the vehicle is likely to be unstable. , So that stable running of the vehicle is realized.
The above processing is performed until the vehicle arrives at the destination.
[0047]
The present invention is not limited to the above embodiment, and various changes or modifications can be made within the scope of technical matters described in the claims.
For example, in the above embodiment, the information relating to the sickness of the occupant is recorded in the information center 2 (S1), but such information is also directly input to the storage device of the mobile navigation device, and is stored in the navigation device. A configuration in which all the processes in the flowchart in FIG. 5 may be performed.
Alternatively, the information center 2 may perform the condition setting in S5, the route setting in S7, the determination in S8, the warning, the sickness determination in S9, and the sickness correction in S10.
[0048]
