The present invention relates to a saddled electric vehicle.
For example, Patent Literature 1 discloses a saddled electric vehicle in which a battery for supplying electric power to a drive source is detachably provided.
Incidentally, in a case of a saddled electric vehicle, there are cases in which the vehicle is moved to a desired location during a state in which the vehicle is not generating a driving force (for example, a neutral state in an engine vehicle).
On the other hand, there are vehicles having a vehicle electronic lock such as smart systems. In such a vehicle, even while the vehicle remains locked due to a vehicle electronic lock in a state in which a battery is removed from the vehicle, the vehicle is required to be easily movable.
An aspect of the present invention is to provide a saddled electric vehicle in which the vehicle can be easily moved even while the vehicle remains locked due to a vehicle electronic lock in a state in which a battery is removed from the vehicle.
One aspect of the present invention is a saddled electric vehicle (1) having a battery (100) that is attachable to and detachable from the vehicle (1) including a vehicle electronic lock (220) which enables the vehicle (1) to be locked and unlocked, a lock control unit (320) which controls the vehicle electronic lock (220), and a sub battery (327) which supplies electric power to the lock control unit (320), in which the lock control unit (320) enables the vehicle (1) to be unlocked in a state in which the battery (100) is removed from the vehicle (1).
According to this configuration, since the lock control unit enables the vehicle to be unlocked in a state in which the battery is removed from the vehicle, the lock of the vehicle can be released. Therefore, even while the vehicle remains locked due to the vehicle electronic lock in a state in which the battery is removed from the vehicle, the vehicle can be easily moved.
In one aspect of the present invention, the vehicle electronic lock (220) may enable the vehicle (1) to be locked and unlocked by authentication with a portable device (223), and the lock control unit (320) may control the vehicle electronic lock (220) on the basis of an authentication result with the portable device (223).
According to this configuration, even while the vehicle remains locked due to the vehicle electronic lock in a state in which the battery is removed from the vehicle, the vehicle can be easily moved using the portable device.
One aspect of the present invention may further include a direct current-direct current converter (DC-DC converter) (326) which connects the battery (100) and the sub battery (327), in which the sub battery (327) may be charged via the DC-DC converter (326) while the vehicle is traveling.
According to this configuration, since the sub battery is charged while the vehicle is traveling, the vehicle electronic lock can be prevented from becoming inoperable due to reduction in power of the sub battery.
In one aspect of the present invention, the vehicle electronic lock (220) may include a handle lock part (211) which enables a handle (2) to be locked and unlocked.
According to this configuration, even while the handle remains locked due to the vehicle electronic lock in a state in which the battery is removed from the vehicle, since the lock of the handle can be released by the handle lock part, the vehicle can be easily moved.
In one aspect of the present invention, the handle lock part (211) may be disposed in a vicinity of a head pipe (12).
According to this configuration, since the handle lock part can be easily accessed compared to a case in which the handle lock part is disposed far away from the head pipe, the lock of the handle can be easily released.
One aspect of the present invention may further include a lock pin (214) which is manually operable, in which an engaging part (202d) that engages with the lock pin (214) in a locked state of the handle (2) may be provided in the head pipe (12).
According to this configuration, since the engagement between the lock pin and the engaging part can be manually released, the lock of the handle can be easily released.
In one aspect of the present invention, the vehicle electronic lock (220) may include a lid lock part (212) which enables a storage lid (8) that stores the battery (100) to be locked and unlocked.
According to this configuration, even while the storage lid remains locked due to the vehicle electronic lock in a state in which the battery is removed from the vehicle, since the lock of the storage lid can be released by the lid lock part, the battery can be easily stored.
According to the present invention, even while the vehicle remains locked due to the vehicle electronic lock in a state in which the battery is removed from the vehicle, the vehicle can be easily moved.

<Control System>
As illustrated in
Electric power from the battery 100 is supplied to the PDU 321 serving as a motor driver via the contactor 324 which is linked to a main switch 260. The electric power from the battery 100 is converted from a direct current into a three-phase alternating current by the PDU 321 and then supplied to the motor 30 which is a three-phase alternating current motor.
An output voltage from the battery 100 is stepped down via a direct current-direct current (DC-DC) converter 326 and is used for charging a sub battery 327 having a rating of 12 V. The sub battery 327 supplies electric power to general electrical components such as a lighting device, and control system components such as a meter 261, a smart unit 221, and the ECU 322. When the sub battery 327 is mounted, electromagnetic locks of various types or the like can be operated even when the battery 100 (hereinafter also referred to as “main battery 100”) is removed.
Since the sub battery 327 is charged via the DC-DC converter 326 in a state in which the main battery 100 is connected, the sub battery 327 is charged when the vehicle travels with the main battery 100 attached. Therefore, general electrical components and control system components can be prevented from becoming inoperable due to reduction in power of the sub battery 327.
Although not illustrated, the PDU 321 includes an inverter having a bridge circuit in which a plurality of switching elements such as transistors are used, smoothing capacitors, and the like. The PDU 321 controls energization for stator winding of the motor 30. The motor 30 performs a power running operation according to control of the PDU 321 to cause the vehicle to travel.
The battery 100 is charged by a charger 325 connected to an external power supply in a state in which it is mounted on the vehicle body. The battery 100 (the front and rear batteries 101 and 102) can be charged by a charger outside the vehicle in a state in which it is removed from the vehicle body.
The front and rear batteries 101 and 102 respectively include battery managing units (BMUs) 101a and 102a which monitor a charge/discharge status, a temperature, or the like. Information monitored by the BMUs 101a and 102a is shared with the ECU 322 when the front and rear batteries 101 and 102 are mounted on the vehicle body. Output request information from an accelerator sensor 329 is input to the ECU 322. The ECU 322 controls driving of the motor 30 via the PDU 321 on the basis of the output request information that has been input.
For example, the ECU 322 may regulate charging/discharging of the battery 100 by controlling the battery 100. For example, the ECU 322 may switch between supplying electric power to the battery 100 and discharging from the battery 100 by controlling the contactor 324 and a relay 262.
A first diode 271 rectifies a current flowing between a high potential side terminal 325P of the charger 325 and a high potential side terminal 101P of the front battery 101. For example, the first diode 271 may cause a current to flow in a direction from the high potential side terminal 325P of the charger 325 toward the high potential side terminal 101P of the front battery 101.
A second diode 272 rectifies a current flowing between the high potential side terminal 325P of the charger 325 and a high potential side terminal 102P of the rear battery 102. For example, the second diode 272 may cause a current to flow in a direction from the high potential side terminal 325P of the charger 325 toward the high potential side terminal 102P of the rear battery 102.
The current flowing through the first diode 271 and the current flowing through the second diode 272 are different from each other. Polarities of the high potential side terminal 325P of the charger 325, the high potential side terminal 101P of the front battery 101, and the high potential side terminal 102P of the rear battery 102 are the same polarity. For example, polarities of the high potential side terminal 325P of the charger 325, the high potential side terminal 101P of the front battery 101, and the high potential side terminal 102P of the rear battery 102 are positive.
The first diode 271 that corresponds to the front battery 101 and the second diode 272 that corresponds to the rear battery 102 are provided to protect respective parts from the following events.
When the first diode 271 and the second diode 272 are provided, backflow of currents from each of the high potential side terminal 101P of the front battery 101 and the high potential side terminal 102P of the rear battery 102 to the high potential side terminal 325P of the charger 325 is prevented.
When the first diode 271 is provided, the front battery 101 is prevented from being short-circuited in a case in which the battery 100 is connected in series.
In a conductor 281 and a conductor 282 that connect the high potential side terminal 101P of the front battery 101 and the high potential side terminal 102P of the rear battery 102, when the first diode 271 and the second diode 272 are provided in opposite directions to each other, in a case in which a short-circuiting failure occurs at one of the front battery 101 and the rear battery 102, short-circuiting on the other is prevented.
The contactor 324 connects or disconnects a connection between a low potential side terminal 101N of the front battery 101 and the high potential side terminal 101P of the rear battery 102. For example, the contactor 324 may connect the low potential side terminal 101N of the front battery 101 and the high potential side terminal 102P of the rear battery 102 in a conductive state. The contactor 324 connects the battery 100 in series in a conductive state and disconnects the serial connection of the battery 100 in a cut-off state. A period in which the contactor 324 is in a cut-off state includes at least a period in which the charger 325 supplies electric power to the battery 100.
The relay 262 connects or disconnects a connection between the low potential side terminal 101N of the front battery 101 and a low potential side terminal 102N of the rear battery 102. For example, the relay 262 may connect the low potential side terminal 101N of the front battery 101 and the low potential side terminal 102N of the rear battery 102 in a conductive state. A period in which the relay 262 is in a conductive state includes at least a period in which the charger 325 supplies electric power to the battery 100.
Opposite ends of the battery 100 connected in series are connected to the PDU 321. The front battery 101 and the rear battery 102 in the battery 100 are connected in series or in parallel by switching states of the contactor 324 and the relay 262. The contactor 324, the relay 262, the first diode 271, and the second diode 272 are examples of connection switching devices. The diodes 271 and 272, the relay 262, and connection parts (branch points P1 to P4) are included in the junction box 323.
<Example of Connection Configuration of Electrical Circuit Drive System>

The high potential side terminal 101P of the front battery 101 and the high potential side terminal 325P of the charger 325 are electrically connected by the first conductor 281. The first diode 271 is inserted into the first conductor 281. For example, a cathode of the first diode 271 may be connected to the high potential side terminal 101P of the front battery 101, and an anode of the first diode 271 may be connected to the high potential side terminal 325P of the charger 325. The first branch point P1 is provided between the anode of the first diode 271 and the high potential side terminal 325P of the charger 325.
The first branch point P1 and the high potential side terminal 102P of the rear battery 102 are electrically connected by the second conductor 282. The second diode 272 is inserted into the second conductor 282. For example, a cathode of the second diode 272 may be connected to the high potential side terminal 102P of the rear battery 102, and an anode of the second diode 272 may be connected to the high potential side terminal 325P of the charger 325 via the first branch point P1. The second branch point P2 is provided between the cathode of the second diode 272 and the high potential side terminal 102P of the rear battery 102.
The second branch point P2 and the low potential side terminal 101N of the front battery 101 are electrically connected by the third conductor 283. A contact of the contactor 324 is inserted into the third conductor 283. The third branch point P3 is provided in the third conductor 283. A position of the third branch point P3 is between the contactor 324 and the low potential side terminal 101N of the front battery 101.
The third branch point P3 and a low potential side terminal 325N of the charger 325 are electrically connected by the fourth conductor 284. A contact of the relay 262 is inserted into the fourth conductor 284.
The low potential side terminal (102N) of a lower potential side battery (the rear battery 102) among the batteries connected in series and the low potential side terminal 325N of the charger 325 are electrically connected by the fourth conductor 284.
The fourth branch point P4 is provided between the cathode of the first diode 271 and the high potential side terminal 101P of the front battery 101.
The fourth branch point P4 and a high potential side terminal of the PDU 321 are electrically connected by the fifth conductor 285.
The fourth branch point P4 and a high potential side terminal 326P of the DC-DC converter 326 are electrically connected by the sixth conductor 286.
A low potential side terminal of the PDU 321 is connected to the low potential side terminal 325N of the charger 325 by the seventh conductor 287.
A low potential side terminal 326N of the DC-DC converter 326 is connected to the low potential side terminal 325N of the charger 325 by the eighth conductor 288.
The electrical circuit may include connections of a monitoring control system indicated by a broken line in the drawing in addition to the connections of the drive system described above. The electrical circuit may include the ECU 322.
<Operation of Electrical Circuit>
The ECU 322 acquires a state of the battery 100 from the respective BMUs 101a and 102a. The ECU 322 detects an operation of a user from the accelerator sensor 329 or the like. The ECU 322 controls the contactor 324, the relay 262, and the PDU 321 on the basis of collected information.
For example, when the battery 100 is charged with electric power from the charger 325, the ECU 322 may perform control such that the contactor 324 is in a cut-off state and the relay 262 is in a conductive state. When the front battery 101 and the rear battery 102 are in a state of being connected in parallel, electric power from the charger 325 is supplied to the front battery 101 and the rear battery 102. In a case of the control state described above, this is in a state in which electric power from the charger 325 can be supplied to the PDU 321. A voltage from the charger 325 to the PDU 321 is the same as a voltage applied between the terminals of the front battery 101.
For example, when the PDU 321 is driven with electric power accumulated in the battery 100, the ECU 322 may perform control such that the contactor 324 in a conductive state and the relay 262 is in a cut-off state. When the front battery 101 and the rear battery 102 are in a state of being connected in series, the front battery 101 and the rear battery 102 supply electric power to the PDU 321. In a case described above, the first diode 271 is reverse-biased. Due to the reverse bias described above, a voltage (for example, 96 V) of the high potential side terminal 101P of the front battery 101 is not applied to the high potential side terminal 102P of the rear battery 102 and the high potential side terminal 325P of the charger 325.
<ABS>
An anti-lock brake system (ABS) 229 is electrically connected to the PCU 320. When drive wheels are locked at the time of sudden braking or the like, the ABS 229 has functions of automatically repeating release and operation of a brake even while the brake remains applied to restore a tire grip force and maintaining traveling stability of the vehicle. The ABS 229 also functions as a vehicle state detection unit capable of detecting a traveling state and a stopped state of the vehicle. For example, the ABS 229 includes a wheel speed sensor (not illustrated) that can detect a wheel speed.
<Operation of PCU>
The PCU 320 also functions as a control unit that controls the vehicle on the basis of detection results of a lid open/close detection unit 225 and the ABS 229.
When the ABS 229 detects a stopped state of the vehicle and the lid open/close detection unit 225 detects an open state of the lid 240 (see
When the ABS 229 detects a traveling state of the vehicle and the lid open/close detection unit 225 detects an open state of the lid 240 (see
Here, the stopped state of the vehicle includes not only a state in which the vehicle is completely stopped but also a state in which the vehicle is substantially stopped (a state in which the vehicle is moving slightly). For example, when a vehicle speed is V, the stopped state of the vehicle may include a state in a range of 0 km/h≤V≤5 km/h.
<Operation of PCU as Lock Control Unit>
The motorcycle includes a smart system 220 (vehicle electronic lock) which enables the vehicle to be locked and unlocked, the PCU 320 which is a lock control unit that controls the smart system 220, and the sub battery 327 which supplies electric power to the PCU 320.
The smart system 220 enables the vehicle to be locked and unlocked by authentication with a remote key 223 (portable device).
The smart system 220 includes the smart unit 221 connected to the PCU 320, an antenna 222 connected to the smart unit 221, a lock knob 211 (handle lock part) connected to the smart unit 221, and a seat switch 212 (lid lock part) connected to the smart unit 221.
The smart unit 221 is a control unit including a microcomputer.
The antenna 222 is a transmitting/receiving antenna for performing communication with the remote key 223.
The lock knob 211 enables the handle 2 (see
The seat switch 212 enables the seat 8 (see
The PCU 320 enables the vehicle to be unlocked with the battery 100 removed from the vehicle. The PCU 320 controls the smart unit 221 on the basis of an authentication result with the remote key 223.
As illustrated in
The downward extending piece 202d (engaging part) that engages with the lock pin 214 in a locked state of the handle 2 (see
As illustrated in
For example, an authentication between the smart system 220 and the remote key 223 is performed by a push operation (ON) of the lock knob 211 when the remote key 223 is brought into an authentication area set in the vehicle in a state in which the transmitting/receiving circuit of the remote key 223 is active. The smart system 220 does not operate when the transmitting/receiving circuit of the remote key 223 is in a stopped state.
A lock that has restricted rotation of the lock knob 211 is released when the authentication between the smart system 220 and the remote key 223 is performed and then the solenoid 216 (see
<Operations of Switches of Various Types or the Like>
Referring to
For example, the smart unit 221 may be supplied with power from the sub battery 327 when the main switch 260 is turned on.
For example, when the main switch 260 and the start switch 228 are turned on, the sub battery 327 is charged by the main battery 100 through the DC-DC converter 326.
When the main switch 260 is ON, the smart unit 221 is supplied with power from the sub battery 327 regardless of presence or absence of the main battery 100. Therefore, the smart unit 221 can be operated by the sub battery 327 without the main battery 100.
When the main switch 260 is ON, the smart unit 221 is charged by the main battery 100 through the DC-DC converter 326.
The PCU 320 detects a state of a lid switch 213. The PCU 320 controls the vehicle on the basis of an open/closed state of the lid 240.
For example, when an open state of the lid 240 is detected before the vehicle travels, the PCU 320 performs control such that a driving force is not generated regardless of an input from the accelerator sensor 329.
Thereby, the vehicle can be prevented from starting to travel in a state in which the charging cord 245 (see
For example, when the open state of the lid 240 is detected while the vehicle is traveling, the PCU 320 may perform control of generating a driving force corresponding to the accelerator sensor 329 until a vehicle speed reaches substantially zero. For example, the vehicle speed can be obtained from the ABS 229 connected to the PCU 320.
The vehicle speed is not limited to being obtained from the ABS 229 and may be obtained from a global positioning system (GPS) or other devices for detecting a vehicle speed.
For example, when the vehicle speed reaches substantially zero or the vehicle is in a stopped state, the PCU 320 performs control such that a driving force is not generated regardless of an input from the accelerator sensor 329.
Accordingly, even when it is assumed that the lid 240 (see
A notification device such as a light emitting diode (LED) indicator (not illustrated) that is changed according to an open/closed state of the lid 240 (see
As described above, in the above-described embodiment, the motorcycle 1 having the main battery 100 that can be attached to and detached from the vehicle body includes the smart system 220 which enables the vehicle to be locked and unlocked, the PCU 320 which controls the smart system 220, and the sub battery 327 which supplies electric power to the PCU 320, in which the PCU 320 enables the vehicle to be unlocked in a state in which the main battery 100 is removed from the vehicle.
According to the present embodiment, when the PCU 320 enables the vehicle to be unlocked in a state in which the main battery 100 is removed from the vehicle, the lock of the vehicle can be released. Therefore, even while the vehicle remains locked due to the smart system 220 in a state in which the main battery 100 is removed from the vehicle, the vehicle can be easily moved.
The smart system 220 enables the vehicle to be locked and unlocked by authentication with the remote key 223, the PCU 320 controls the smart system 220 on the basis of an authentication result with the remote key 223, and thereby the following effects are achieved. Even while the vehicle remains locked due to the smart system 220 in a state in which the main battery 100 is removed from the vehicle, the vehicle can be easily moved using the remote key 223.
Since the DC-DC converter 326 connecting the main battery 100 and the sub battery 327 is provided, the sub battery 327 is charged via the DC-DC converter 326 while the vehicle is traveling, and thereby the following effects are achieved. Since the sub battery 327 is charged while the vehicle is traveling, the smart system 220 can be prevented from becoming inoperable due to reduction in power of the sub battery 327.
Since the smart system 220 includes the lock knob 211 which enables the handle 2 to be locked and unlocked, the following effects are achieved. Even while the handle 2 remains locked due to the smart system 220 in a state in which the main battery 100 is removed from the vehicle, since the lock of the handle 2 can be released by the lock knob 211, the vehicle can be easily moved.
Since the lock knob 211 is disposed in the vicinity of the head pipe 12, the following effects are achieved. Since the lock knob 211 can be easily accessed compared to a case in which the lock knob 211 is disposed far away from the head pipe 12, the lock of the handle 2 can be easily released.
The lock knob 211 includes the lock pin 214 that can be manually operated, the downward extending part 202d that engages with the lock pin 214 in a locked state of the handle 2 is provided in the head pipe 12, and thereby the following effects are achieved. Since the engagement between the lock pin 214 and the downward extending part 202d can be manually released, the lock of the handle 2 can be easily released.
Since the smart system 220 includes the seat switch 212 that enables the seat 8 in which the main battery 100 is stored to be locked and unlocked, the following effects are achieved. Even while the seat 8 remains locked due to the smart system 220 in a state in which the main battery 100 is removed from the vehicle, since the lock of the seat 8 can be released by the seat switch 212, the main battery 100 can be easily stored.
In the above-described embodiment, an example in which the battery disposition structure includes two unit batteries has been described, but the present invention is not limited thereto. For example, the battery disposition structure may include one or three or more unit batteries.
In the above-described embodiment, an example of a cantilever structure in which only a left portion of the fender is fixed to the fender stay has been described, but the present invention is not limited thereto. For example, a cantilever structure in which only a right portion of the fender is fixed may be used. Alternatively, a double-lever structure in which both the left and right portions of the fender are fixed may be used.
The present invention is not limited to the above-described embodiment, and the saddled electric vehicles described above includes general vehicles on which a driver straddles the vehicle body to ride, including not only motorcycles (such as motorized bicycle and scooter type vehicle) but also three-wheeled vehicles (such as vehicles with two front wheel and one rear wheel as well as vehicles with one front wheel and two rear wheels) or four-wheeled vehicles.
The configuration in the above-described embodiment is an example of the present invention, and various changes can be made without departing from the scope of the present invention such as replacing the components of the embodiment with well-known components.
