  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram illustrating a schematic system configuration of a traveling device according to the present embodiment. FIG. 2 is a front view illustrating a schematic configuration of the traveling device according to the present embodiment. A travel device 10 according to the present embodiment includes a posture sensor 2, a rotation sensor 3, a pair of wheel drive units 4L and 4R, a control device 5, and a pair provided in a vehicle body 1 as shown in FIG. Step sensors 16L and 16R.

  The vehicle body 1 is configured as, for example, a stand-up type coaxial two-wheeled vehicle that can be ridden while a passenger is standing on the chassis 6. The coaxial two-wheeled vehicle is configured such that, for example, the passenger moves forward and backward by moving the center of gravity back and forth, and the passenger can turn left and right by moving the center of gravity left and right.

  The posture sensor 2 detects posture information such as the pitch angle, pitch angular velocity, pitch angular acceleration, roll angle, roll angular velocity, roll angular acceleration of the chassis 6 of the vehicle body 1. The posture sensor 2 detects, for example, the pitch angle (tilt angle) of the chassis 6 that is generated when the passenger moves the center of gravity back and forth, and the chassis 6 that is generated when the passenger moves the center of gravity left and right. The roll angle (tilt angle) of the dividing steps 9L and 9R can be detected.

  The posture sensor 2 is connected to the control device 5 and outputs the detected posture information to the control device 5. Note that the posture sensor 2 is configured by, for example, a gyro sensor, an acceleration sensor, an angle sensor, and the like. The pitch axis is an axis corresponding to the axles of the pair of wheels 7L and 7R. The roll axis is an axis that passes through the center of the chassis 6 and is parallel to the traveling direction of the vehicle body 1.

  The rotation sensor 3 detects rotation information such as the rotation angle, rotation speed, and rotation acceleration of the wheels 7L and 7R provided on the vehicle body 1. The rotation sensor 3 is connected to the control device 5 and outputs the detected rotation information to the control device 5.

  The pair of wheel drive units 4L, 4R is a specific example of drive means, and drives the vehicle main body 1 by driving a pair of left and right wheels 7L, 7R rotatably provided on the vehicle main body 1. Each wheel drive unit 4L, 4R can be constituted by, for example, an electric motor and a reduction gear train connected to the rotating shaft of the electric motor so as to be able to transmit power. Each wheel drive unit 4L, 4R is connected to the control device 5 via drive circuits 8L, 8R, and drives each wheel 7L, 7R according to a control signal from the control device 5.

  The control device 5 is configured so that the vehicle body 1 performs a desired traveling (forward, reverse, acceleration, deceleration, stop, left turn, right turn, etc.) while performing the inverted control to maintain the inverted state, for example. Each wheel drive unit 4L, 4R is controlled to control the rotation of each wheel 7L, 7R. Further, the control device 5 performs feedback control, robust control, and the like based on the posture information of the vehicle body 1 detected by the posture sensor 2 and the rotation information of the wheels 7L and 7R detected by the rotation sensor 3. Well-known control is performed.

  For example, the control device 5 uses the wheel drive units 4L and 4R to set the wheels 7L, the wheel 7L according to the pitch angle of the chassis 6 detected by the attitude sensor 2 when the passenger moves the center of gravity back and forth. By controlling the rotation of 7R, the vehicle body 1 is moved forward or backward. Further, the control device 5 moves the wheel drive units 4L and 4R according to the roll angles of the division steps 9L and 9R of the chassis 6 detected by the attitude sensor 2 when the passenger moves the center of gravity to the left and right. Control is performed to cause a rotation difference between the left and right wheels 7L and 7R, and the vehicle body 1 is turned left or right.

  Further, for example, the control device 5 multiplies the pitch angle of the chassis 6 detected by the attitude sensor 2 by a predetermined control gain to calculate the rotational torque of each wheel 7L, 7R. And the control apparatus 5 controls each wheel drive unit 4L and 4R so that the calculated rotational torque may arise in each wheel 7L and 7R. As a result, the control device 5 turns the wheels 7L and 7R in the direction in which the chassis 6 is tilted so that the position of the center of gravity of the vehicle body 1 returns to the vertical line passing through the axles of the wheels 7L and 7R. Take control. Further, the control device 5 adds an appropriate rotational torque to each of the wheels 7L and 7R, thereby maintaining the inverted state so that the pitch angle of the chassis 6 does not exceed a certain value, and further In accordance with the posture information from the sensor 2, movement control of the vehicle body 1 such as forward, reverse, stop, deceleration, acceleration, left turn, and right turn can be performed.

  With the configuration of the vehicle control as described above, the vehicle main body 1 can be moved forward and backward by moving the center of gravity forward and backward and tilting the chassis 6 forward and backward, and the passenger moves the center of gravity left and right. Left and right turning can be performed by inclining 6 to the left and right.

  The control device 5 includes, for example, a CPU (Central Processing Unit) 5a that performs control processing, arithmetic processing, and the like, a ROM (Read Only Memory) 5b that stores a control program executed by the CPU 5a, an arithmetic program, and the like, processing data The hardware configuration is mainly composed of a microcomputer composed of a RAM (Random Access Memory) 5c or the like for temporarily storing them.

  The pair of step sensors 16L and 16R are provided in the pair of divided steps 9L and 9R, respectively. Each step sensor 16L, 16R is configured by a load sensor or the like that can detect a passenger's load applied to each divided step 9L, 9R, and outputs the detected load to the control device 5. Based on the load detected by each of the step sensors 16L and 16R, the control device 5 is in a state where only one rider's foot is on one of the divided steps 9L and 9R, and both feet are in a pair of divided steps 9L and 9R, respectively. It is possible to detect a riding state or a state where none of the feet are on the division steps 9L and 9R.

  As shown in FIG. 2, the vehicle main body 1 is configured as a coaxial two-wheeled vehicle, and includes a chassis 6, wheels 7L and 7R, division steps 9L and 9R, a handle 11, and the like. The pair of left and right divided steps 9L and 9R is an example of a step plate on which the driver gets on. The chassis 6 supports the divided steps 9L and 9R so that the posture can be changed in the roll direction. The pair of left and right wheels 7L and 7R are rotatably supported by the chassis 6. The handle 11 is an operation lever that changes the postures of the divided steps 9L and 9R in the roll direction via the chassis 6.

  Each of the divided steps 9L and 9R is carried by the driver on one foot, and is composed of a pair of flat plates that are formed to be approximately the same as or slightly larger than the size of the human foot. The chassis 6 is arranged in parallel with each other on the vehicle body upper member 12 and the vehicle body lower member 13, and is arranged on the left and right in parallel with each other and is rotatable with the vehicle body upper member 12 and the vehicle body lower member 13. It is comprised as a parallel link mechanism which has a pair of side member 14L, 14R connected.

  Between the vehicle body upper member 12 and the vehicle body lower member 13 of the parallel link mechanism, the angles formed by the vehicle body upper member 12 and the vehicle body lower member 13 and the pair of side members 14L and 14R are respectively maintained at right angles. A pair of coil springs 15L and 15R that generate a spring force are interposed. In addition, wheel drive units 4L and 4R are attached to the outer surfaces of the pair of side members 14L and 14R, respectively. As described above, when the pair of wheels 7L and 7R supported by the pair of side members 14L and 14R via the pair of wheel drive units 4L and 4R are placed on a flat road surface, the rotation centers of the pair of wheels 7L and 7R are the same axis. Will match on the line. In addition, although the vehicle main body 1 is comprised as a coaxial two-wheeled vehicle, it is not restricted to this, For example, it can apply to the arbitrary vehicles which drive operation is performed by a passenger | crew's center-of-gravity movement, and performs inversion control.

  By the way, when the passenger gets on the vehicle body, for example, if the handle is moved unintentionally or the vehicle body is tilted back and forth, the vehicle body moves in the front-rear direction according to the operation. For this reason, it may be difficult to board the vehicle body.

  Therefore, when the control device 5 according to the present embodiment detects the start of boarding of the vehicle main body 1 by the occupant, the control device 5 performs the inverted control, and the position where the boarding is safe and easy, for example, the occupant moves the vehicle main body. Position control is performed such that the vehicle main body 1 is always returned to the position X1 (hereinafter referred to as a boarding start position X1) when boarding is started.

  Thereby, for example, when the passenger gets on the vehicle main body 1, the handle 11 is moved back and forth, or the vehicle main body 1 is tilted back and forth, and the vehicle main body 1 moves in the front-rear direction according to the operation. Even in this case, the vehicle body 1 can be returned to the boarding start position X1 by the position control. Therefore, since the distance between the passenger and the vehicle main body 1 is appropriately maintained when the passenger gets on the vehicle main body 1, the passenger can board the vehicle main body 1 safely and easily.

  FIG. 3 is a block diagram illustrating a schematic system configuration of the control device. The control device 5 includes a boarding detection unit 51 that detects the start of boarding by the passenger on the vehicle body 1, a command value generation unit 52 that generates a torque command value, and a torque command value generated by the command value generation unit 52. And a control unit 53 that controls each wheel drive unit 4L, 4R.

  The boarding detection unit 51 detects, for example, a state in which only one foot of the passenger is riding on one of the divided steps 9L and 9R based on the loads detected by the step sensors 16L and 16R. The start of boarding the vehicle main body 1 is detected. The boarding detection unit 51 outputs a start signal to the command value generation unit 52 when detecting the start of boarding of the vehicle main body 1 by the passenger.

  Further, the boarding detection unit 51 detects, for example, a state in which both feet are on the pair of divided steps 9L and 9R based on the loads detected by the step sensors 16L and 16R, so that the vehicle by the passenger It detects that boarding to the main body 1 is completed. The boarding detection unit 51 outputs a completion signal to the command value generation unit 52 when detecting that the boarding of the vehicle main body 1 by the passenger is completed.

  The command value generation unit 52 generates a torque command value for controlling each wheel drive unit 4L, 4R, and outputs the generated torque command value to the control unit 53. Further, when the command value generation unit 52 receives the start signal from the boarding detection unit 51, the torque command value that constantly returns the vehicle main body 1 to the boarding start position X1 when the start signal is received while performing the inversion control. Is generated.

Here, the command value generation unit 52 calculates the torque command value using, for example, the following equation (1). In the following equation (1), β is the pitch angle of the chassis 6 detected by the attitude sensor 2, β ′ is the pitch angular velocity, x is the vehicle position of the vehicle body 1, x ′ is the speed of the vehicle body 1, and K _pp Is a pitch angle gain, K _dp is a pitch angular velocity gain, K _px is a vehicle position gain, and K _dx is a velocity gain. Of the parameters, those with a subscript r are command values, and those without a subscript r are detected values. Further, β _r ′ is 0, x _r is the boarding start position X1 when the passenger starts the boarding operation, and x _r ′ is 0.

Torque command value = K _pp (β _r -β) + K _dp (β _r ′ -β ′) + K _px (x _r -x) + K _dx (x _r ′ -x ′) (1) Equation

  The command value generation unit 52 can calculate the vehicle position x and the speed x ′ of the vehicle main body 1 based on the rotation information of the wheels 7L and 7R detected by the rotation sensor 3.

  Further, when receiving a completion signal from the boarding detection unit 51, the command value generation unit 52 stops the position control and generates a torque command value for continuing the inversion control. Here, the command value generation unit 52 calculates the torque command value using, for example, the following equation (2). In addition, the command value generation unit 52 considers safety and rideability, for example, stops the turn control until only the forward / reverse control is performed until the completion of boarding of the passenger by receiving the completion signal from the boarding detection unit 51. A torque command value for performing is generated.

Torque command value = K _pp (β _r -β) + K _dp (β _r '-β') (2) Equation

  The control unit 53 controls each wheel drive unit 4L, 4R by transmitting a control signal corresponding to the torque command value generated by the command value generation unit 52 to each wheel drive unit 4L, 4R. The driving of each wheel 7L, 7R is controlled.

  Next, a method for controlling the traveling device 10 according to the present embodiment will be described in detail. FIG. 4 is a flowchart illustrating an example of a control processing flow of the traveling device according to the present embodiment.

  When the passenger starts to ride on the vehicle main body 1, as shown in FIG. 5 (a), from the state of holding the vehicle main body 1 by holding the handle 11, as shown in FIG. 5 (b), Put one foot on the dividing steps 9L and 9R. At this time, the boarding detection unit 51 detects a state in which only one of the passenger's legs is on one of the divided steps 9L and 9R based on the loads detected by the step sensors 16L and 16R. The start of boarding the main body 1 is detected (step S101).

  The boarding detection unit 51 detects the start of boarding of the vehicle main body 1 by the passenger (YES in step S101), and determines that the boarding posture is in a horizontal state as shown in FIG. 5C. (YES in step S102), a start signal is output to the command value generation unit 52. The boarding detection unit 51 outputs a start signal to the command value generation unit 52 as soon as it detects the start of boarding of the vehicle body 1 by the passenger without determining the boarding posture of the chassis 6. Also good.

  The command value generation unit 52 generates a torque command value using the above equation (1) (step S103), and outputs the generated torque command value to the control unit 53. Based on the torque command value generated by the command value generation unit 52, the control unit 53 performs position control to constantly return the vehicle main body 1 to the boarding start position X1, while controlling the wheel drive units 4L and 4R. (Step S104).

  For example, as illustrated in FIG. 5D, when the vehicle position of the vehicle main body 1 moves forward from the boarding start position X1 and the vehicle main body 1 moves away from the passenger, the control unit 53 causes the vehicle main body 1 to move. By moving backward to return to the boarding start position X1, the wheel drive units 4L and 4R are controlled so that the vehicle main body 1 is brought closer to the passenger. Thereby, the passenger can safely and easily board the chassis 6 in an easy posture.

  On the other hand, as shown in FIG. 5E, when the vehicle position of the vehicle main body 1 moves rearward from the boarding start position X1, and the vehicle main body 1 approaches the passenger, the control unit 53 gets on the vehicle main body 1. By moving forward to return to the start position X1, the wheel drive units 4L and 4R are controlled so that the vehicle body 1 is slightly separated from the passenger. Thereby, the passenger can take an appropriate distance from the chassis 6 and can board the chassis 6 safely and easily.

  As shown in FIG. 5 (f), the boarding detection unit 51 detects a state in which both feet are riding on the pair of divided steps 9L and 9R based on the loads detected by the step sensors 16L and 16R. Then, it is detected that the boarding by the passenger is completed on the vehicle main body 1 (step S105). The boarding detection unit 51 outputs a completion signal to the command value generation unit 52 when detecting that the boarding of the vehicle main body 1 by the passenger is completed (YES in step S105).

  When the command value generation unit 52 receives the completion signal from the boarding detection unit 51, the command value generation unit 52 generates a torque command value using the equation (2) and outputs the torque command value to the control unit 53. Based on the torque command value generated by the command value generation unit 52, the control unit 53 controls the wheel drive units 4L and 4R to stop the position control and continue the inversion control (step S106).

  As described above, in the traveling device 10 according to the present embodiment, when the control device 5 detects the start of boarding of the vehicle main body 1 by the passenger, the control device 5 always returns the vehicle main body 1 to the boarding start position X1 while performing the inversion control. Correct position control. Thereby, even when the position of the vehicle main body 1 is shifted due to a traveling operation or the like that is not intended by the rider, the vehicle main body 1 can be returned to the boarding start position X1 where the boarding is safe and easy. Therefore, the passenger can board the vehicle body 1 safely and easily.

  In addition, this invention is not limited to the said embodiment, It is possible to change suitably in the range which does not deviate from the meaning. For example, in the above-described embodiment, the command value generation unit 52 generates a torque command value that always returns the vehicle main body 1 to the boarding start position X1, but the present invention is not limited to this. A torque command value that is a pitch angle (target posture) of the chassis 6 that returns the vehicle body 1 to an easy position may be generated.

  For example, as shown in FIG. 5D, when the vehicle position of the vehicle main body 1 is in front of the boarding start position X1, and the distance between the passenger and the vehicle main body 1 is large, the command value generation unit 52 is A torque command value for tilting the chassis 6 backward is generated according to the distance. Then, the control unit 53 moves backward to return the vehicle body 1 to the boarding start position X1 based on the pitch angle that is the backward tilt of the chassis 6 detected by the attitude sensor 2, and approaches the passenger.

  On the other hand, as shown in FIG. 5E, when the vehicle position of the vehicle main body 1 is behind the boarding start position X1 and the distance between the passenger and the vehicle main body 1 is reduced, the command value generation unit 52 is A torque command value that tilts the chassis 6 forward is generated according to the distance. Then, the control unit 53 moves the vehicle body 1 forward to return to the boarding start position X1 based on the pitch angle that is the forward tilt of the chassis 6 detected by the attitude sensor 2, and moves away from the passenger.

The command value generation unit 52 calculates a torque command value using the above equation (2). At this time, if x _r ≦ x, β _r = K _xf (x _r -x), and if x _r > x, β _r = K _xb (x _r -x). K _xf is a front position error conversion coefficient, and K _xb is a rear position error conversion coefficient.

  When receiving a completion signal from the boarding detection unit 51, the command value generation unit 52 generates a torque command value so as to be the pitch angle at the start of boarding, and outputs the torque command value to the control unit 53.

  In the above embodiment, when the command value generation unit 52 receives the start signal from the boarding detection unit 51, the command value generation unit 52 generates a torque command value that always returns the vehicle body 1 to the boarding start position X1 while performing the inversion control. However, the present invention is not limited to this, and a torque command value may be generated such that the interval between the chassis 6 and the passenger becomes a predetermined distance while performing the inversion control. Note that the distance between the chassis 6 and the passenger (for example, a landing foot or torso) can be detected by a distance sensor (for example, a camera, an ultrasonic sensor, a radar sensor) provided on the chassis 6 or the like. it can. Thereby, when a passenger boardes the chassis 6 of the vehicle main body 1, the distance between the chassis 6 and the passenger is maintained at a predetermined distance optimum for the boarding. For this reason, the passenger can board the vehicle body 1 safely and easily.

  Furthermore, in the said one Embodiment, although the control apparatus 5 performs position control which returns the vehicle main body 1 to the boarding start position X1 by moving the vehicle main body 1 back and forth, it is not restricted to this, and the vehicle main body 1 is changed to right and left. Position control for returning the vehicle main body 1 to the boarding start position X1 by turning may be performed, or position control for returning the vehicle main body 1 to the boarding start position X1 by turning the vehicle main body 1 forward and backward and left and right may be performed. Good.

  In the above-described embodiment, the present invention has been described as a hardware configuration, but the present invention is not limited to this. The present invention can also realize arbitrary processing by causing a CPU (Central Processing Unit) to execute a computer program. In this case, the computer program can be provided by being recorded on a recording medium, or can be provided by being transmitted via the Internet or another communication medium.
