The electric vehicle control device 1 may be configured to control the entire electric two-wheeled vehicle 100 as ECU (Electronic Control Unit). Next, each constituent element of the electric vehicle control device 1 will be described in detail.
The control unit 10 inputs information from various devices connected to the electric vehicle control device 1, and drives and controls the motor generator 3 through the power conversion unit 30. The detailed information about the control unit 10 will be described later.
The storage unit 20 stores: information used by the control unit 10 and a program for operating the control unit 10. The storage unit 20 is, for example, a nonvolatile semiconductor memory, but may not be limited to this.
The power conversion unit 30 converts the dc power of the battery 2 into ac power and supplies the ac power to the motor generator 3. As shown in fig. 2, the power conversion unit 30 is constituted by a three-phase full-bridge circuit. The semiconductor switches Q1, Q3, Q5 are high-side switches, and the semiconductor switches Q2, Q4, Q6 are low-side switches. The control terminals of the semiconductor switches Q1 to Q6 are electrically connected to the control unit 10. A smoothing capacitor C is provided between the power supply terminal 30a and the power supply terminal 30 b. The semiconductor switches Q1 to Q6 are, for example, MOSFETs, IGBTs, or the like.
As shown in fig. 2, the semiconductor switch Q1 is connected to: between the power supply terminal 30a to which the positive electrode of the battery 2 is connected and the input terminal 3a of the motor generator 3. Similarly, the semiconductor switch Q3 is connected to: between the power supply terminal 30a and the input terminal 3b of the motor generator 3.

The input terminal 3a is a U-phase input terminal, the input terminal 3b is a V-phase input terminal, and the input terminal 3c is a W-phase input terminal.
The battery 2 can be charged and discharged. Specifically, the battery 2 supplies dc power to the power conversion unit 30 when discharging. In addition, when the battery 2 is charged with ac power supplied from an external power supply 13 such as a commercial power supply, the ac power supplied from the power supply 13 is converted by the charger 9 and then charged with dc power. When the battery 2 is charged with ac power output from the motor generator 3 in accordance with rotation of the wheels 8, the ac power output from the motor generator 3 is converted by the power conversion device 100 and then charged with dc voltage.
The battery 2 includes a Battery Management Unit (BMU). The battery management unit transmits information about the voltage of the battery 2 and the state (charging rate, etc.) of the battery 2 to the control section 10.
The number of the batteries 2 is not limited to one, and may be plural. The battery 2 is, for example, a lithium ion battery, but may be another type of battery. The battery 2 may be constituted by a battery of a different kind (for example, a lithium ion battery and a lead battery).
The motor generator 3 outputs torque for driving the wheels 8 by electric power supplied from the battery 2. Alternatively, the motor generator 3 outputs electric power as the wheels 8 rotate.
Specifically, the motor generator 3 is driven by the ac power supplied from the power conversion portion 30, and outputs torque for driving the wheels 8. Torque can also be achieved by: the control unit 10 outputs PWM signals having the energization timing and the duty ratio calculated based on the target torque to the semiconductor switches Q1 to Q6 of the power conversion unit 30 to control the same. That is, the torque may also be calculated by: the control unit 10 controls the electric power supplied from the battery 2 to the motor generator 3.
The motor generator 3 is mechanically connected to the wheel 8, and rotates the wheel 8 in a desired direction by torque. In the present embodiment, the motor generator 3 is mechanically connected to the wheels 8 without a clutch. The type of the motor generator 3 is not particularly limited.
The motor generator 3 outputs ac power in accordance with rotation of the wheels 8. Specifically, when the motor generator 3 is rotated by an external force or after the rotation speed thereof is reduced, the motor generator 3 outputs ac power (i.e., regenerative power). As a case where the rotation speed of the motor generator 3 is reduced, for example, a case where the vehicle is braked after braking during running is illustrated. Further, as a case where the motor generator 3 is rotated by an external force, for example, a case where the motor generator 3 is driven by inertia in a state where electric power is not supplied from the battery 2 or a case where the motor generator is driven on a slope (downhill) may be mentioned.
In addition, the case where the motor generator 3 is rotated by an external force includes: in order to be able to rotate the wheel 8 by an external force (for example, a user's hand), the motor generator 3 may be rotated in a state where the wheel 8 is separated from the ground after the stand of the wheel 8 is erected, and the wheel 8 is rotated by the external force.
The ac power output from the motor generator 3 is converted into dc power by the power conversion unit 30, and the battery 2 is charged (i.e., regenerative charging) with the converted dc power.
The charger 9 charges the battery 2 with ac power supplied from the power supply 13. The charger 9 has: an AC-DC converter 91; a converter control unit 92; and a charging plug 93. The charging plug 93 is connected to the power source 13 through a socket not shown. The AC-DC converter 91 converts an alternating-current voltage input from the power supply 13 into a direct-current voltage through the charging plug 93. The converter control section 92 controls the power conversion of the AC-DC converter 91.
The angle sensor 4 is a sensor that detects the rotation angle of the rotor of the motor generator 3 in order to detect the rotation speed of the motor generator 3. As shown in fig. 3, magnets (sensor magnets) of N and S poles are alternately mounted on the peripheral surface of the rotor of the motor generator 3. The angle sensor 4 is constituted by, for example, a hall element, and detects a change in the magnetic field caused by the rotation of the motor generator 3. The magnet may be provided inside a flywheel (not shown).
As shown in fig. 3, the angle sensor 4 includes: a U-phase angle sensor 4U; a V-phase angle sensor 4V; and a W-phase angle sensor 4W. In the present embodiment, the U-phase angle sensor 4U and the V-phase angle sensor 4V are configured to: the rotor of the motor generator 3 is at an angle of 30 °. Likewise, the V-phase angle sensor 4V and the W-phase angle sensor 4W are configured to: the rotor of the motor generator 3 is at an angle of 30 °.
As shown in fig. 4, the U-phase angle sensor 4U, the V-phase angle sensor 4V, and the W-phase angle sensor 4W output: a pulse signal (i.e., a detection signal of the rotation angle) corresponding to the phase of the rotor angle (angle position).
As shown in fig. 4, a number indicating the rotor stage (rotor stage number) is assigned to each predetermined rotor angle. The rotor stages represent the angular positions of the rotor of the motor generator 3, and in the present embodiment, rotor stage numbers 1, 2, 3, 4, 5, 6 are assigned to each 60 ° electrical angle. The rotor stage is defined by a combination of the levels (H-stage or L-stage) of the output signals of the U-phase angle sensor 4U, the V-phase angle sensor 4V, and the W-phase angle sensor 4W. For example, rotor stage number 1 is (U-phase, V-phase, W-phase) = (H, L, H), and rotor stage number 2 is (U-phase, V-phase, W-phase) = (H, L).
The throttle position sensor 5 detects: the accelerator operation amount set according to the accelerator operation by the user is transmitted to the control unit 10 as an electrical signal. When the user wants to accelerate, the accelerator operation amount becomes large.
The meter 7 is a display (e.g., a liquid crystal panel) provided on the electric two-wheeled vehicle 100, and displays various information. Specifically, the meter 7 is shown with: information such as the running speed of the electric motorcycle 100, the remaining power of the battery 2, the current time, and the running distance. In the present embodiment, the meter 7 is provided on a steering wheel (not shown) of the electric two-wheeled vehicle 100.
Next, the control unit 10 of the electric vehicle control device 1 will be described in detail.
The control unit 10 performs: and control of charging (i.e., regenerative charging) the battery 2 with the electric power output from the motor generator 3.
The control unit 10 also performs: and control of charging the battery 2 with the electric power supplied from the power supply 13. Specifically, the control unit 10 performs control of converting an AC voltage into a DC voltage by the AC-DC converter 91: control of charging the battery 2 with electric power supplied from the power supply 13. Specifically, the control unit 10 outputs a charge permission signal for permitting the battery 2 to be charged with the electric power supplied from the power source 13 to the converter control unit 92, thereby controlling the AC-DC converter 91 by the converter control unit 92 to control the charging of the battery 2.
In a state where the battery 2 can be charged with the electric power supplied from the power supply 13, the control portion 10 detects the rotation speed of the motor generator 3 in the output electric power state based on the pulse signal output from the angle sensor 4.
As one example, as shown in fig. 4, the control unit 10 calculates the rotation speed of the motor generator 3 based on a time t from a falling edge of the output of the V-phase rotor angle sensor to a rising edge of the output of the U-phase rotor angle sensor.
In a state where the battery 2 can be charged by the electric power supplied from the power source 13, the motor generator 3 is in a state where the electric power is output, for example, a state where the vehicle 8 is lifted up and the wheel 8 is separated from the ground, and the wheel 8 can be rotated by an external force.
Therefore, the state where the wheels 8 leave the ground after the stand of the vehicle 8 is erected is: the charging plug 93 is connected to the power source 13, and is in a state in which the battery 2 can be charged, and also in a state in which the electric power can be generated in the motor generator 3 after the wheel 8 is rotated by hand.
The control unit 10 is configured to: by restricting such charging of the battery 2 in a state where the battery can be charged from both the power supply 13 and the motor generator 3, the supply of excessive electric power to the battery 2 from both the power supply 13 and the motor generator 3 is avoided.
Specifically, after the rotation speed of the motor generator 3 is detected, the control unit 10 waits for control to charge the battery 2 with the electric power supplied from the power source 13 until the detected rotation speed is equal to or lower than the threshold speed for a threshold time.
Then, after the detected rotation speed of the motor generator 3 is equal to or lower than the threshold speed for the threshold time, the control unit 10 performs: control of charging the battery 2 with electric power supplied from the power supply 13.
The threshold speed of the motor generator 3 may be a threshold value of the absolute value of the rotational speed.
More specifically, the control unit 10 may wait for the AC-DC converter 91 to perform control for converting the AC voltage into the DC voltage after the charging plug 93 is connected to the power source 13 until the state in which the rotational speed of the motor generator 3 is equal to or lower than the threshold speed continues for the threshold time.
The control unit 10 may control the AC-DC converter 91 to convert the AC voltage into the DC voltage after the threshold speed or lower is maintained for a threshold time. The control of the AC-DC converter 91 may be performed by the converter control unit 92.
For example, the control unit 10 may determine whether the rotational speed is equal to or lower than the threshold speed in a predetermined determination period, and increase the count value of the duration of the state equal to or lower than the threshold speed when the rotational speed is equal to or lower than the threshold speed. The control unit 10 waits for control of charging the battery with the electric power supplied from the power supply until the count value reaches the completion value corresponding to the threshold time.
The control unit 10 may perform: and control of charging the battery 2 with the electric power supplied from the power supply 13.
Further, the control unit 10 may reset the count value when the rotation speed of the motor generator 3 is not equal to or lower than the threshold speed. Instead of counting up until the completion value of the count value (increase in the count value), counting down until the completion value of the count value (decrease in the count value) may be performed.
Control method for electric two-wheeled vehicle 100
Hereinafter, a control method of the electric two-wheeled vehicle 100 according to the first embodiment will be described with reference to a flowchart of fig. 5 as an example of an electric vehicle control method. Further, the flowchart of fig. 5 will be repeated as needed.
First, the charging plug 93 is connected to the power source 13 (step S1).
After the charging plug 93 is connected to the power source 13, the control unit 10 determines whether or not the motor generator 3 is in a state of outputting electric power (step S2).
For example, the control unit 10 may be configured to: whether the motor generator 3 is in a state of outputting electric power is determined by detecting rotation of the motor generator 3 by the angle sensor 4 in a state where electric power is not supplied from the battery 2 to the motor generator 3, detecting rotation of the motor generator 3 in a state where the accelerator operation amount is zero, or the like.
When the motor generator 3 is in a state of outputting electric power (step S2: yes), the control unit 10 resets (n=0) a count value n for counting a duration of a state in which the rotational speed of the motor generator 3 is equal to or less than a threshold value (i.e., a low-speed state) (step S3). On the other hand, when the motor generator 3 is not in a state of outputting electric power (step S2: no), the control portion 10 allows the battery 2 to be charged with electric power supplied from the power source 13 by outputting a charge permission signal to the converter control portion 92 (step S9).
After resetting the count value n, the control unit 10 acquires the pulse signal of the angle sensor 4 (step S4).
After acquiring the pulse signal of the angle sensor 4, the control unit 10 calculates the rotation speed of the motor generator 3 based on the acquired pulse signal (step S5).
After calculating the rotation speed of the motor generator 3, the control unit 10 determines whether or not the absolute value of the calculated rotation speed of the motor generator 3 is equal to or less than a threshold value (step S6).
When the absolute value of the rotational speed of the motor generator 3 is equal to or less than the threshold value (Yes in step S6), the control unit 10 increases the count value (n=n+1) (step S7). On the other hand, when the absolute value of the rotational speed of motor generator 3 is not equal to or less than the threshold value (step S6: no), control unit 10 resets the count value (step S3).
After the count value is incremented, the control section 10 determines whether the count value has reached the completion value (step S8). This determination corresponds to determining whether or not the state in which the rotational speed of the motor generator 3 is equal to or lower than the threshold speed has continued for the threshold time.
When the count value reaches the completion value (step S8: yes), the control section 10 outputs a charge permission signal to the converter control section 92. On the other hand, when the count value does not reach the completion value (step S8: no), the control section 10 acquires the pulse signal of the angle sensor 4 (step S4).
In the illustration of fig. 5, after the charging plug 93 is connected to the power source 13, the control unit 10 performs the processing from step S2 to step S8. In contrast, the control unit 10 may confirm that the charging plug 93 is connected to the power supply 13 after the count value reaches the completion value. At this time, the control unit 10 may wait for confirmation that the charging plug 93 is connected to the power source 13 and output a charging enable signal to the converter control unit 92.
Hereinafter, the operation of the first embodiment will be described.
As described above, in the first embodiment, after the rotation speed of the motor generator 3 in the output power state is detected (calculated), the control unit 10 waits for control of charging the battery 2 with the electric power supplied from the power supply 13 until the detected rotation speed is equal to or lower than the threshold speed for the threshold time. Then, after the state where the rotational speed of the motor generator 3 is equal to or lower than the threshold speed continues for the threshold time, the control unit 10 performs: control of charging the battery 2 with the electric power supplied from the power supply 13.
Therefore, the battery 2 can be charged with the electric power supplied from the power source 13 while the motor generator 3 is sufficiently restrained from generating electric power in accordance with the rotation of the wheels 8.
The result is that: the problem of supplying excessive power to the battery 2 from both the power supply 13 and the motor generator 3 can be prevented, and the battery 2 can be charged appropriately.
As described above, in the first embodiment, the control unit 10 performs control of converting an AC voltage into a DC voltage in the AC-DC converter 91 by the converter control unit 92, and performs: control of charging the battery 2 with electric power supplied from the power supply 13. At this time, after the charging plug 93 is connected to the power source 13 (step S1 of fig. 5), until the state where the rotational speed of the motor generator 3 is equal to or lower than the threshold speed continues for a threshold time (step S8 of fig. 5), the control unit 10 waits for control to convert the ac voltage supplied from the power source 13 into the dc voltage, and after the state where the rotational speed of the motor generator 3 is equal to or lower than the threshold speed continues for the threshold time, it performs: control of converting the ac voltage into the dc voltage (step S9 of fig. 5).
Therefore, since the conversion of the AC power and the DC power input from the power supply 13 to the AC-DC converter 91 can be waited for before the state where the rotational speed of the motor generator 3 is equal to or lower than the threshold speed continues for the threshold time, the battery 2 can be accurately charged while the motor generator 3 is sufficiently suppressed from generating power in accordance with the rotation of the wheels 8.
As described above, in the first embodiment, the control unit 10 uses the threshold value of the absolute value of the rotation speed as the threshold speed of the rotation speed of the motor generator 3, so that the battery 2 can be charged with the electric power supplied from the power source 13 in a state in which the motor generator 3 is sufficiently suppressed from generating electric power in accordance with the rotation of the wheel 8, regardless of the rotation direction of the wheel 8.
As described above, in the first embodiment, the control unit 10 determines whether or not the rotational speed of the motor generator 3 is equal to or lower than the threshold speed in the predetermined determination period (step S5 in fig. 5). When the rotational speed is equal to or lower than the threshold speed, the control unit 10 increases the count value of the duration of the state equal to or lower than the threshold speed (step S7 in fig. 5), and waits for control of charging the battery 2 with the electric power supplied from the power supply 13 until the count value reaches the completion value corresponding to the threshold time (step S8). Then, after the count value reaches the completion value, the control unit 10 performs: control of charging the battery 2 with the electric power supplied from the power supply 13 (step S9).
Therefore, it is possible to wait for control of charging the battery 2 with the electric power supplied from the power supply 13 before the count value reaches the completion value equivalent to the threshold time. In this way, the battery 2 can be charged accurately with simple control while the motor generator 3 is sufficiently suppressed from generating electric power in accordance with the rotation of the wheels 8.
As described above, in the first embodiment, when the rotational speed of the motor generator 3 is not equal to or lower than the threshold speed, the control unit 10 resets the count value of the duration of the state equal to or lower than the threshold speed.
Therefore, it is possible to accurately wait for the state in which the rotational speed is equal to or lower than the threshold speed for the threshold time, and to perform: control of charging the battery 2 with the electric power supplied from the power supply 13. In this way, the battery 2 can be charged more accurately while the motor generator 3 is sufficiently suppressed from generating electric power in accordance with the rotation of the wheels 8.
Second embodiment
Hereinafter, an electric motorcycle 100 according to a second embodiment will be described with reference to fig. 6. As shown in fig. 6, the electric motorcycle 100 according to the second embodiment further includes, in addition to the configuration of the first embodiment: an under-seat housing portion 14 as an example of a housing portion; and a seat switch 15 as an example of the closed state detecting section.
The under-seat housing portion 14 is a space that can be opened and closed for housing the battery 2 provided under the seat of the electric two-wheeled vehicle 100. The seat is attached to the vehicle body such that the under-seat housing portion 14 can be moved (e.g., rotated) in a direction in which it can be opened and closed by, for example, a hinge mechanism or the like. While driving, the under-seat housing portion 14 is covered with a seat, thereby enabling the driver to sit on the seat. On the other hand, when charging the battery 2, the under-seat storage portion 14 is opened by moving the seat, and the charging plug 93 is taken out.
When the seat is moved to open the under-seat storage portion 14, the seat switch 15 outputs a disconnection signal to the control portion 10, the disconnection signal indicating a detection result of the open state of the under-seat storage portion 14. On the other hand, when the under-seat storage portion 14 is locked by moving the seat, the seat switch 15 outputs an on signal to the control portion 10, the on signal indicating a detection result of the locked state of the under-seat storage portion 14. In addition, the under-seat housing portion 14 can be locked in a state in which the charging plug 93 is removed.
The seat switch 15 may be a mechanical switch that is turned on by being pressed by the seat when the seat is closed, and turned off by being released when the seat is opened, for example.
When the state where the rotational speed of the motor generator 3 is equal to or lower than the threshold speed continues for the threshold time and the closed state (on signal) of the under-seat housing portion 14 is detected by the seat switch 15, the control portion 10 performs: control of charging the battery 2 with the electric power supplied from the power supply 13.
Hereinafter, a control method of the electric motorcycle 100 according to the second embodiment will be described with reference to a flowchart of fig. 7, focusing on differences from the first embodiment. Further, the flowchart of fig. 7 will be repeated as needed.
As shown in fig. 7, in the second embodiment, after the count value reaches the completion value (step S8: yes), the control unit 10 determines whether the seat switch 15 has been turned on (step S10).
When the seat switch 15 is turned on (Yes in step S10), the control unit 10 outputs a charge permission signal to the converter control unit 92 (step S9). On the other hand, when the seat switch 15 is not turned on (step S10: no), the control unit 10 resets the count value (step S3).
As described above, according to the second embodiment, since the charging of the battery 2 in the state where the seat is opened can be inhibited, the problem of supplying excessive electric power to the battery 2 from both the power source 13 and the motor generator 3 can be prevented, and the charging of the battery 2 can be properly performed while preventing foreign matter from being mixed in the under-seat housing portion 14.
At least a part of the electric vehicle control device 1 (control unit 10) described in the above embodiment may be configured by hardware or software. In the case of using software, a program for realizing at least a part of the functions of the control unit 10 may be stored in a recording medium such as a floppy disk or a CD-ROM, and may be executed by a computer after being read. The recording medium is not limited to a removable recording medium such as a magnetic disk or an optical disk, and may be a fixed recording medium such as a hard disk device or a memory.
The program for realizing at least a part of the functions of the control unit 10 may be distributed via a communication line (including wireless communication) such as the internet. Next, the program may be distributed via a wired line or a wireless line such as the internet in a state where the program is encrypted, modulated, or compressed, or may be distributed after being stored in a recording medium.
