As illustrated in FIG. 1, the vehicle propulsive force control system according to the first embodiment is carried by a vehicle user who is registered in the parent device 1, the propulsive force control device 20, and the parent device that are installed in the vehicle. It consists of a plurality of slave units 30 and 40.
The base unit 1 includes a first transmission antenna 2, a first CPU 3, a first transmission unit 4, an authentication unit 5, a first storage unit 6, a first reception unit 7, a rotation detection unit 8, and a first The receiving antenna 9 and the receiver 10 are included.
The subunit | mobile_unit 30 has 2nd CPU31, 2nd memory | storage part 32, magnetic flux angle detection part 33, battery 34, 2nd transmission antenna 35, 2nd transmission part 36, 2nd reception antenna 37, and 2nd. The receiving unit 38 is configured. The configuration of a plurality of registered child devices 40 different from the child device 30 is the same as that of the child device 30 and has the same function as the child device 30.

More specifically, the master unit 1 includes a first transmission antenna 2 for transmitting authentication information to the registered slave units 30 and 40, a first CPU 3 for controlling the master unit 1, and information The data transmitted from the registered slave unit is received via the first transmission unit 4 for transmitting the information and the first reception antenna 9 for receiving information from the registered slave unit. Transmission / reception is performed with the receiver 10 that performs the above-described operation.
Further, the ID of the slave unit received from the first receiving unit 7 of the master unit 1 that receives authentication information from the registered slave unit, and a plurality of registered in the first storage unit 6 of the master unit 1 The IDs of the respective slave units 30 and 40 are compared, and the slave unit registered in the authentication unit 5 of the master unit 1 is authenticated.
Furthermore, when the parent device 1 authenticates the child device 30 registered in the parent device 1, information on the three-dimensional magnetic flux density of the radio wave transmitted from the first transmitting antenna 2, the magnetic flux density detected in the three dimensions, and the child device Is received by the master unit 1 from the slave unit 30 via the first reception antenna 9 of the master unit 1 (information of F1 and F2 in FIG. 3 described later).
Based on the information on the received magnetic flux density and the information on the angle, the base unit 1 detects the angle detected earlier in time from the information on the received angles at least twice the previous reception and the current reception (described later). The rotation detection unit 8 detects the rotation of the slave unit 30 from the difference between F1 in FIG. 3 and an angle detected later in time (information on F2 in FIG. 3 described later). If the authentication is successful, the propulsion of the vehicle, that is, the operation of the propulsive force control device 20 is permitted, and by detecting the rotation of the slave unit 30, the vehicle falls and the vehicle user falls from the vehicle. Is determined, the propulsive force of the vehicle is stopped, that is, the propulsive force control device 20 is controlled to stop the propulsive force of the vehicle.

  On the other hand, the slave unit 30 operates the second CPU 31 that controls the slave unit, the second storage unit 32 that stores an ID for authenticating the master unit 1, and the slave unit 30. Information from the base unit 1, a battery 34 that is a power source for power transmission, a second transmission unit 36 that transmits information via the second transmission antenna 35 for transmitting information from the handset 30 to the base unit 1 Is transmitted / received by the second receiving unit 38 that receives information from the base unit 1 via the second receiving antenna 37 for receiving. The magnetic flux angle detector 33 detects the three-dimensional magnetic flux density of the radio wave transmitted from the first transmission antenna 2 and the angle between the slave and the magnetic flux density in three dimensions on each axis.

  In addition, the subunit | mobile_unit 30 can register the some subunit | mobile_unit 40 with the same structure as the subunit | mobile_unit 30 with respect to the main | base station 1, and memorize | stores different ID in the memory | storage part 41 with each subunit | mobile_unit.

  Next, functions of each component of the parent device 1 and the child device 30 having these components and a series of operations will be described with reference to FIG.

First, the keyless operation by the master unit 1 and the slave unit 30 will be described.
A vehicle user who is a legitimate user has a child device 30 whose ID is registered in the parent device 1, and the parent device periodically transmits a request signal from the first transmission unit 4 to the child device 30 as an LF. (LowFrequency: 125 kHz long wave, for example) is transmitted via the first transmission antenna 2 and authentication is performed to determine whether a registered slave unit exists. When the handset 30 exists in a range where the request signal can reach, the handset 30 receives the request signal by the second receiving unit 38 of the receiving IC via the second receiving antenna 37, and the second storage unit 32. The RF (Radio Frequency: for example, 315 MHz) UHF (Ultra High Frequency) signal is transmitted from the second transmitter 36 via the second transmitter antenna 35. Send. Although specific radio waves have been described here as an example, radio waves to be used may use bands other than those described above, and may be changed according to the size of the area to be authenticated, the frequency allowed in the country of use, etc. May be.
The base unit 1 receives the RF signal transmitted from the handset 30 by the receiver 10 via the first receiving antenna 9, and extracts the ID information from the reception information by the first receiving unit 7, The authentication unit 5 determines whether the slave unit matches the first storage unit 6, and if the ID is authenticated, the system can be turned on simply by pressing a button (not shown). The driving force of the engine or the like can be started.

The basic control for the keyless operation is as described above, but the slave unit 30 detects the magnetic flux of the signal transmitted from the first transmitter 4 and the angle of the slave unit for each three-dimensional axis. It has an angle detection unit 33, and can detect the magnetic flux of the received signal and the magnetic flux angle of the slave unit 30 without adding new parts, and simultaneously with the transmission signal at the time of authentication, It can be transmitted to the base unit 1.
Here, referring to FIG. 1 and FIG. 3, as an example, detection of detecting a fall of a user 102 from a ship that is propelling the sea is being promoted in the sea 100. Explain the logical concept. Based on the radio wave transmitted from the first transmission antenna (LF antenna) 2 of the parent device 1 installed in the vehicle 101, the child device 30 is in each of the three-dimensional axes (x axis, y axis, z axis). The magnetic flux density Dx, Dy, Dz, which is the strength of the magnetic flux, and the angles θxy, θyz, θzx between the axes measured by the magnetic flux angle detection unit 33 are measured, and the measurement information is transmitted to the parent device 1.
In the keyless system that is the prior art, the base unit 1 calculates a vector sum from the magnetic flux densities Dx, Dy, and Dz, and estimates the distance between the first transmitting antenna 2 and the handset unit 30 from the magnetic flux density p [nT]. The communication area was detected.
In the vehicle propulsive force control system according to the first embodiment of the present application, in addition to the distance information, angles θxy, θyz, and θzx of the axes (x-axis, y-axis, and z-axis) of the magnetic flux densities Dx, Dy, and Dz are calculated. Use to detect falls.
FIG. 3A illustrates angle detection when the slave unit 30 is not fallen. The slave unit 30 measures the magnetic flux density of each xyz axis and measures the magnetic flux density p1 from the vector sum of these magnetic flux densities. F1 is the result of measuring the magnetic flux from the first transmitting antenna (LF antenna) 2 and the angle of the slave unit 30 between the axes, and obtains the angles θ1xy, θ1yz, and θ1zx. When the user 102 moves in the operation area of the vehicle (ship) 101 while carrying the slave unit 30, the magnetic flux densities Dx, Dy, Dz and the angles θ1xy, θ1yz, θ1zx are periodically detected. When the angles θ1xy, θ1yz, θ1zx between the three axes before and after the time are compared with θ1xy, θ1yz, θ1zx, the angles θ1xy, θ1yz, θ1zx and the angles θ1xy, θ1yz, θ1zx before and after the time are compared. The amount of change is small.
Next, FIG. 3 (b) illustrates the detection result of the angle when the user 102 falls from the vehicle (ship) 101. The magnetic flux density p1 in FIG. 3 (a) is as shown in FIG. 3 (b). The magnetic flux density is p2. As for the angle detected periodically, at the time of the fall, at least one of the angles θ2xy, θ2yz, and θ2zx (θ2yz in this example) of the respective axes of F2, which is the detection result of the angle of each axis, was measured last time. As is obvious when compared with the angle at the time, for example, the angles θ1xy, θ1yz, and θ1zx in FIG.
Therefore, the change in the angle of any one of the three angles θ1xy, θ1yz, θ1zx, θ2xy, θ2yz, and θ2zx before and after the periodically measured time changes more than a specified value. For example, when the angle of at least one of the three-dimensional axes (x-axis, y-axis, z-axis) has changed greatly, it is determined that the slave unit 30 is rotating, so that the slave unit 30 is not rotating. It is detected that the user 102 of the vehicle carrying the machine 30 is falling from the vehicle 101.
In the case described above, the vehicle user 102 determines that the vehicle 101 has fallen from the vehicle 101 when the angle of one of the three-dimensional axes (x-axis, y-axis, z-axis) changes by more than a specified value. However, by detecting changes in the angles of two or three of the three-dimensional axes (x-axis, y-axis, and z-axis) depending on the use situation of the vehicle, The detection accuracy of rotation can be improved.
In recent years, the number of vehicles equipped with this keyless device has increased, and go-carts used in races including four-wheeled passenger cars, buggy-like cars traveling on rough roads, automatic vehicles including two-wheelers and three-wheelers. The rate of installation is increasing with the expansion of motorcycles, snowmobiles used on snowy roads, jet skis, water bikes such as water vehicles, power boats, and cruisers.

  As described above, the master unit 1 detects the magnetic flux angle transmitted from the slave unit 30 at least twice, so that the rotation detection unit 8 can detect the difference of the magnetic flux angle before and after the slave unit 30. Rotation and rotation angle can be detected. In other words, all the system components described for the keyless operation are combined, and a new function for detecting the magnetic flux and the rotation of the slave unit 30 is added, so that the vehicle falls without adding new hardware components. It is possible to determine the abnormal state of the vehicle or the vehicle user such as a vehicle user falling from the vehicle and control the vehicle driving force to suppress or stop the vehicle driving force to ensure safety.

  Next, the vehicle propulsive force control system illustrated in FIG. 1 is used as a method for determining whether the vehicle has fallen or the vehicle has fallen from the vehicle based on the rotation angle of the slave unit 30 detected by the rotation detection unit 8. A description will be given with reference to FIG. 2 which is a flowchart showing an example of an operation for determining whether the vehicle falls and the vehicle user falls.

In FIG. 2, the rotation angle of the subunit | mobile_unit 30 is detected by the rotation detection part 8 by step S1.
Next, in step S2, the rotation angle of the slave unit 30 detected in step S1 is a predetermined angle that is a predetermined determination angle for vehicle overturn and vehicle user fall set in advance according to the vehicle use situation. If it is not larger, the process ends without stopping the propulsive force of the vehicle without determining that the vehicle has fallen or the vehicle user has fallen.
In step S2, if the rotation angle detected in step S1 is greater than the respective determination angles of vehicle fall and vehicle user fall set in advance according to the vehicle use situation, in step S3, It is determined that the vehicle has fallen or the vehicle has fallen, and the propulsive force control device 20 is instructed to stop the propulsive force of the vehicle, and the propulsive force is stopped, thereby stopping the propulsive force of the vehicle and causing the vehicle to run away. It is possible to prevent secondary damage after a vehicle falls or after a vehicle user falls.

  If the vehicle propulsion control system of this application is applied to a vehicle equipped with a vehicle keyless device that starts the engine without key operation, there is no cost increase, and the vehicle falls, and the vehicle user's vehicle In the event of an abnormal condition of the vehicle or the vehicle user such as a fall, the vehicle user is a person who operates the vehicle body and the vehicle like an operator clip for detecting a fall or fall from the vehicle etc. It is not necessary to stop or suppress the propulsive force of the vehicle in a state where the vehicle is physically constrained, and it is possible to automatically stop or suppress the propulsive force in an emergency.

Embodiment 2. FIG.
In the first embodiment, the example of the system for determining the fall of the vehicle and the fall of the vehicle user from the vehicle based on the rotation angle detected from the slave device 30 has been described. However, in the second embodiment, the slave device is described. With reference to FIG. 4, a system for determining whether the vehicle has fallen or the vehicle has fallen from the vehicle based on the distance detected by the vehicle will be described.
Since the basic configuration has been described with reference to FIG. 1 and FIG. 2, the second embodiment will be described mainly with respect to the contents newly added to FIG. I will omit the same or similar explanation.

  Although the rotation detection unit 8 is provided in FIG. 1, in FIG. 4, a distance detection unit 11 that detects the distance between the first transmission antenna 2 of the parent device 1 and the child device 30 is used instead of the rotation detection unit. Is provided.

  In the first embodiment, the master unit 1 has exemplified the system that detects the rotation angle from the first transmission antenna 2, but in the second embodiment, the slave unit 30 is not the rotation angle but the slave unit 30 The magnetic flux density of the signal transmitted from the first transmission unit 4 is measured for each three-dimensional axis, and the parent device 1 calculates a vector sum from the magnetic flux density for each three-dimensional axis measured by the child device 30. As a result, the distance between the first transmission antenna 2 of the base unit 1 and the handset 30 is detected by the distance detection unit 11, and the distance detected by the distance detection unit 11 is set in advance according to the use state of the vehicle. When the vehicle is farther than the set distance, it is determined that the vehicle has fallen or the vehicle user has fallen, and the propulsive force control device 20 is controlled to stop or suppress the propulsive force of the vehicle. Stop the propulsion of the vehicle To control to suppress, preventing runaway of the vehicle, can be prevented after the vehicle overturning, or after tumble of the vehicle of the user, a secondary damage. The preset distance set according to the use state of the vehicle means, for example, setting the set distance to the size of the vehicle. In this case, the distance between the first transmission antenna 2 and the slave unit 30 is set. When it is detected that the distance is greater than or equal to the size of the vehicle, it is possible to detect the fall of the vehicle or the fall of the user of the vehicle.

Embodiment 3 FIG.
In the first embodiment, the example of the system that determines the fall of the vehicle and the fall of the vehicle user from the vehicle according to the rotation angle detected by the slave unit 30 has been described, but in the third embodiment, the vehicle An example of a system for increasing the accuracy of each determination of a fall and a fall of a user from a vehicle will be described with reference to FIGS.
Since the basic configuration has been described with reference to FIGS. 1 to 3, the third embodiment will be described mainly with respect to the contents newly added to FIG. 5, and FIGS. I will omit the same or similar explanation. FIG. 6 is a diagram illustrating a logical concept of detecting the rotation of the slave unit using the vehicle propulsive force control system illustrated in FIG. 5, in which the user of the ship from the ship when the vehicle is a ship. It is a conceptual diagram which shows the other example which detects a fall, Comprising: (a) is the state in which the user of the vehicle has not fallen from the ship, that is, the conceptual diagram at the time of non-fall, (b) is the vehicle user from the ship It is a conceptual diagram at the time of falling, that is, falling.

In the first embodiment, an example of a system in which the base unit 1 detects the rotation angle from one first transmission antenna 2 has been described, but in the third embodiment, referring to FIGS. 5 and 6 As another example, a logical concept of detection for detecting a fall of a user 102 from a ship that is propelling the sea and a ship that is propelling the sea 101 will be described.
FIG. 6 shows an example in which two LF antennas are installed. The first first transmission antenna 2No1 and the second first transmission antenna 2No2 are installed on the vehicle 101. Specifically, the first first transmission antenna 2No1 is installed at the front part of the vehicle 101, and the second first transmission antenna 2No2 is installed at the rear part of the vehicle 101. In addition, 1st 1st transmission antenna 2No1 and 2nd 1st transmission antenna 2No2 are installed apart from the preset setting distance.
FIG. 6A is an example in which the angle θ1 of each radio wave from the two first first transmission antennas 2No1 and the second first transmission antenna 2No2 to the handset 30 at the time of non-falling is detected. .
Next, FIG. 6B is an example in which the angle θ2 of each radio wave from the two first first transmission antennas 2No1 and the second first transmission antenna 2No2 to the handset 30 at the time of falling is detected. is there.
Since the master unit 1 is the same as that of the first embodiment until the information on the magnetic flux density detected from the slave unit 30 is received, the description is omitted. The difference is that the angle θ between the two antennas is detected from the respective angles of the two first first transmitting antennas 2No1 and the second first transmitting antenna 2No2, and the angles θ1 and θ2 Based on the change, the rotation detector 8 detects the rotation of the slave unit.
As is apparent from a comparison of the angle θ1 in FIG. 6A at the time of non-falling and the angle θ2 in FIG. 6B at the time of falling, the angle θ2 at the time of falling is the angle θ1 at the time of non-falling. Has changed significantly since. That is, it can be determined that the user 102 has fallen from the vehicle 101 when the change in angle changes by more than a specified value.
By changing the number of the first transmission antennas 2 to the base unit 1 to a plurality of the first transmission antennas 2 spaced apart from each other, a change in angle with the handset 30 can be detected from the plurality of first transmission antennas 2. By detecting the angle change from the plurality of first transmitting antennas 2, the accuracy of detecting the rotation angle of the slave unit 30 is improved. Accordingly, it is possible to improve the accuracy of each determination of a vehicle falling or a vehicle user falling from the vehicle.

  In addition, since the angle between the radio wave transmitted from the first transmission antenna 2 of the base unit 1 and the slave unit changes depending on the direction of the magnetic flux of the radio wave, the first transmission antennas 2 added to a plurality of units are connected to the first transmission antenna 2 respectively. Since the change in angle from each of the first transmission antennas is increased by arranging the mounting angles of the first transmission antennas to be different from each other, the accuracy of detecting the rotation angle of the slave unit 30 is improved. It is possible to improve the accuracy of each determination of the fall of the vehicle or the fall of the vehicle user from the vehicle.

  In the first embodiment, the slave unit 30 has been described to detect the magnetic flux density. However, in the third embodiment, the first transmission antenna 2 of the master unit 1 and the slave unit 30 are detected from the result of detecting the magnetic flux density. The distance detection part 11 which detects the distance is provided. If the angle of the handset 30 alone is changed, depending on the driving state of the vehicle, a fall of the vehicle or a fall of the user from the ride may be erroneously detected. By comparing the amount of change in the distance between one transmission antenna 2 and the slave unit 30, if a change over a predetermined distance that takes into account the driving state of the vehicle is detected, the vehicle falls or the user of the vehicle By determining whether the vehicle has fallen from the vehicle, it is possible to improve the determination accuracy of the vehicle falling and the vehicle user falling from the vehicle.

In the first embodiment, the master unit 1 explained the system for detecting the rotation angle from one first transmission antenna 2, but in the third embodiment, the master unit 1 rotates the slave unit 30. In addition, a rotation speed detection unit 12 that detects the rotation speed from the difference in rotation angle detected a plurality of times is provided.
If there is a situation where the handset 30 rotates slowly depending on the driving state, it may be erroneously determined that the vehicle has fallen or the vehicle has fallen from the vehicle. When the rotational speed detected by the speed detection unit 12 is equal to or higher than a preset rotational speed that determines that the vehicle has fallen and the vehicle has fallen from the vehicle according to the use state of the vehicle. By determining that the vehicle has fallen or the vehicle user has fallen from the vehicle, it is possible to improve the accuracy in determining whether the vehicle has fallen or the vehicle user has fallen from the vehicle.

  The base unit 1 includes a propulsion speed detection unit 13 that detects the traveling or traveling speed of the vehicle measured by the propulsive force control device 20. It is necessary to prevent the spread of secondary damage by stopping the propulsion force earlier as the vehicle travels or travels faster. Therefore, when the traveling speed or the traveling speed of the vehicle detected by the propulsion speed detection unit 13 is high, the propulsion stop after the determination of the vehicle overturning or the vehicle user falling from the vehicle is accelerated, If the driving or traveling speed is slow, the propulsion stop is slowed, and the propulsion stop time is changed according to the traveling or traveling speed, so that the vehicle falls and the user falls from the vehicle. The accuracy of the determination can be improved.

  The base unit 1 includes a propulsion acceleration / deceleration detector 14 that detects the traveling or traveling speed at least twice and detects the acceleration / deceleration from the detected speed difference. When the vehicle falls or the user falls from the vehicle, the acceleration / deceleration of the vehicle changes greatly. Therefore, the acceleration / deceleration detected by the propulsion acceleration / deceleration detecting unit 14 indicates the use state of the vehicle. Predetermined vehicle falls and vehicle users falling from the vehicle when the acceleration / deceleration set value is greater than the set value to determine whether the vehicle has fallen or the vehicle has fallen from the vehicle. Thus, it is possible to improve the accuracy of the determination of the fall of the vehicle and the fall of the vehicle user from the vehicle.

  In the third embodiment, the characteristics of improving the fall / fall determination accuracy by each detection unit have been described. However, even when each detection unit is determined alone, the fall / fall determination accuracy can be improved. By combining a plurality of parts according to the usage situation, the fall and fall determination accuracy can be further increased.

  In the first embodiment and the second embodiment, the base unit 1 has been described to stop the propulsion force of the vehicle when it is determined that the vehicle has fallen or the vehicle has fallen from the user's vehicle. There are conditions for misjudgment depending on the judgment conditions. In the third embodiment, the base unit 1 includes a warning unit 17 that warns a vehicle user who is a user when a fall or fall determination is made. If it is erroneously determined that the vehicle has fallen and the vehicle has fallen from the vehicle, unnecessary or unintentional vehicle propulsion stoppage will occur and a new danger will occur. When the vehicle or the vehicle user's condition (the state of the slave unit) is difficult to accurately determine, if the vehicle falls or the vehicle user falls from the vehicle, the vehicle is promoted. The warning unit 17 generates a warning by the warning unit 17 without stopping the power suddenly, and can notify the vehicle user as a user in advance that the propulsive force may be stopped. .

  The base unit 1 also includes a propulsion force stop avoidance switch 21. When the vehicle user who is a user operates the propulsion force stop avoidance switch 21, an unnecessary propulsion force stop due to a fall or fall erroneous determination is made. To avoid. The warning unit 17 warns the vehicle user who is a user of the possibility of stopping propulsion as a first step in a state where it is difficult to determine whether the vehicle falls or falls, and determines that the user who is the user is not falling or falling. In such a case, the user who is a vehicle can operate the propulsion stop stop switch 21 to avoid the wrong propulsion stop.

  Furthermore, when the vehicle user who is the user does not operate the propulsion stop avoidance switch 21 in spite of warning from the warning unit 17, the base unit 1 is set in advance according to the use state of the vehicle. The propulsive force is automatically stopped after the predetermined time has elapsed. If the user determines that the vehicle has not fallen or the user has fallen from the vehicle, the propulsion stop avoidance switch 21 is operated. If the warning is not an erroneous determination, the user is the vehicle. Since the user does not operate the propulsive force stop switch, the propulsive force of the vehicle is automatically stopped, so that the propulsive force stop avoidance switch 21 is difficult due to the vehicle falling and the vehicle falling from the vehicle. Even the propulsion of the vehicle can be stopped reliably.

  Further, if the base unit 1 does not operate the propulsion force stop avoidance switch 21 in spite of warning from the warning unit 17, after a predetermined time set in advance according to the use state of the vehicle, Although the propulsive force is automatically stopped, the use state varies depending on the vehicle, and therefore the situation in which the propulsive force stop avoidance switch 21 can be operated is different. Therefore, the propulsive force stop that can change the predetermined time after the warning is performed. A start time changing unit 15 is provided, and by changing the predetermined time according to the use state of the vehicle, stop of unnecessary propulsive force due to the vehicle falling over and erroneous determination of the vehicle user falling from the vehicle Can be avoided.

Further, when detecting the fall of the vehicle and the fall of the vehicle from the vehicle, the base unit 1 compares the movement distance, the rotation angle, the rotation speed, the propulsion speed, and the propulsion acceleration / deceleration of the slave unit 30. Although the fall or fall is determined, since the determination condition varies depending on the use state of the vehicle, the fall / fall determination condition changing unit 16 capable of changing the determination accuracy of the fall and the fall is provided. By changing the determination value accordingly, a vehicle propulsive force control system with high accuracy can be provided.
In addition, explanation was given to detect a fall or fall without adding new parts by diverting a keyless device, but at least one of the rotation angle and the distance to the communication source is detected in smartphones that have become popular in recent years A similar effect can be obtained without using a keyless device by installing an application and acquiring at least one of rotation information and distance information by an in-vehicle parent device using a smartphone as a child device.

  In any of the first to third embodiments, the master unit 1 is automatically turned on when the prime mover such as the vehicle engine is started, and the slave units 30 and 40 are operated by the operation of the vehicle user. When the slave unit 30 or 40 approaches the range in which wireless communication with the master unit 1 is possible, the slave unit 30 or 40 automatically enters the on state, and while the prime mover is operating, The on-states of the slave units 30 and 40 are continuously maintained.
