In particular, hydrogen fuel cell vehicles, biodiesel vehicles, electric vehicles, etc. are being attracted attention as a replacement for a vehicle composed of an internal combustion engine.

An electric vehicle is configured to charge electrical energy into a battery, and the battery supplies electrical energy to a motor.

The electric vehicle may include a battery electric vehicle (BEV), a plug-in hybrid EV (PHEV), a hybrid EV (HEV), and the like. HEV (Hybrid EV) is a vehicle that combines two types of power with an internal combustion engine and an electric motor, and is characterized by higher fuel efficiency and higher efficiency than a conventional internal combustion engine vehicle. The Plug-in Hybrid EV (PHEV) is a vehicle designed to charge the HEV's battery from the outside, and the BEV (Electric Vehicle) is a vehicle driven only by the battery and the electric motor.

HEV, PHEV, and BEV vehicles commonly use electric energy to drive vehicles. HEV is configured to generate electric energy in a vehicle and charge the battery, and PHEV and BEV are supplied from outside to receive batteries. Is configured to charge.

Electric vehicles such as PHEVs and BEVs have charging ports for charging batteries, and the charging ports are arranged at various positions such as a portion adjacent to the wheel of the vehicle or the front of the vehicle.

It works (S8). Specifically, when the lock controller 30 receives the unlock signal from the charge controller 50 in the open state of the cover 14, the lock controller 30 charges the unlock signal received from the charge controller 50. It transfers to the lock actuator 20 via the charge unlock relay 32b of the relay 32, and the lock pin 21 of the lock actuator 20 moves to the unlock position UP. In this case, when the cover 14 opens the opening 12 of the housing 11, and the charging plug 15 is connected to the charging receptacle 13, the lock pin 21 of the lock actuator 20 is charged as shown in FIG. 4. The charging plug 15 may be unlocked by being separated from the lock groove 15a of the plug 15.

In step S7 described above, when the lock controller 30 receives the lock signal from the charge controller 50, the lock controller 30 transmits the lock signal to the lock actuator 20, through which the lock actuator 20 locks. It works (S4). Specifically, when the lock controller 30 receives the lock signal from the charge controller 50 in the open state of the cover 14, the lock controller 30 charges the lock signal received from the charge controller 50. The lock 32 is transmitted to the lock actuator 20 through the charge lock relay 32a of the relay 32, and the lock pin 21 of the lock actuator 20 moves to the lock position LP. At this time, when the cover 14 opens the opening 12 of the housing 11, and the charging plug 15 is connected to the charging receptacle 13, the lock pin 21 of the lock actuator 20 is charged with the charging plug 15. The charging plug 15 may be locked by being coupled to the lock groove 15a.

When the set time has elapsed after the lock actuator 20 is locked in operation S8, the lock controller 30 determines whether the unlock operation of the lock actuator 20 is normally performed (S9).

Referring to step S9 in detail, if the set time elapses after the lock actuator 20 is operated by the lock, the lock controller 30 may detect the level of the current applied to the lock actuator 20. If the level of the detected current corresponds to the second set level, the lock pin 21 of the lock actuator 20 can be regarded as being in the unlocked position UP. Therefore, the lock controller 30 unlocks the lock actuator 20. It can be determined that the operation is normal, and if the detected current level does not correspond to the second set level, it can be considered that the lock pin 21 of the lock actuator 20 is not located at the unlock position UP, so that the lock controller 30 may determine that the unlocking operation of the lock actuator 20 is not normal. Here, the second set level may be set to a current level detected (feedback) by the lock actuator 20 when the lock pin 21 of the lock actuator 20 is located at the unlock position UP.

In the above-described step S9, if the lock controller 30 determines that the unlock operation of the lock actuator 20 is not normally performed, the lock controller 30 retries the unlock operation of the lock actuator 20. (S9-1).

When the cover 14 closes the opening 12 of the housing 11 and the door and the cover 14 are unlocked, the lock controller 30 receives the lock signal from the door lock / unlock controller 40. The controller 30 transmits the lock signal to the lock actuator 20 through the charge lock relay 32a, so that the lock pin 21 of the lock actuator 20 moves to the lock position LP so that the cover 14 is moved. Can be locked. At this time, when the cover 14 unintentionally opens the opening 12 of the housing 11 while the lock pin 21 of the lock actuator 20 moves to the lock position LP, the lock actuator 20 The lock pin 21 may move to the lock position LP. Thus, the lock pin 21 protrudes as the lock pin 21 of the lock actuator 20 is positioned at the lock position LP while the cover 14 opens the opening 12 of the housing 11. This protruding lock pin 21 not only closes the opening 12 of the housing 11 or prevents the charging plug 15 from being connected to the charging receptacle 13, but also the closing of the cover 14. It is not possible and also the lock controller 30 cannot control the lock actuator 20 in conjunction with the lock operation / unlock operation of the door.

In this way, the cover 14 unintentionally opens the opening 12 of the housing 11 during the locking operation of the lock actuator 20 with the cover 14 closing the opening 12 of the housing 11. In this case, the lock pin 21 of the lock actuator 20 moves to the lock position LP and protrudes, so that the closing of the cover 14 and the electrical connection of the charging plug 15 and the charging receptacle 13 are impossible. To prevent disengagement, the lock controller 30 may be configured to perform a fail safety function for the lock actuator 20 and the cover 14.

6 is a flow chart illustrating fail safety logic of the lock actuator 20 and the cover 14 in the closed state of the cover.

The lock controller 30 determines whether the cover 14 closes the opening 12 of the housing 11 by the first sensor 17 (S21), and the cover 14 of the housing 11. If it is determined that the opening 12 is closed, the lock controller 30 receives a door lock signal or a door unlock signal from the door lock / unlock controller 40 (S22).

It is determined whether the lock controller 30 receives the door lock signal (S23), and when the lock controller 30 receives the door lock signal from the door lock / unlock controller 40, the lock controller 30 locks the door lock. In response to the signal, the lock signal is transmitted to the lock actuator 20 through the charge lock relay 32a, through which the lock actuator 20 operates to lock (S24).

During the lock operation of the lock actuator 20, the lock controller 30 determines whether the cover 14 is opened (S25). Specifically, while the lock pin 21 of the lock actuator 20 moves to the lock position LP, the lock controller 30 allows the cover 14 to open the opening 12 of the housing 11. Judge whether

In step S25, if it is determined that the cover 14 opens the opening 12 of the housing 11 during the lock operation of the lock actuator 20, the lock controller 30 immediately stops the lock operation of the lock actuator 20. The lock controller 30 unlocks the lock actuator 20 (S26). Specifically, if the cover 14 opens the opening 12 of the housing 11 before the lock pin 21 of the lock actuator 20 completely moves to the lock position LP, the lock controller 30 The lock operation of the lock actuator 20 is stopped by transmitting the unlock signal to the lock actuator 20 through the charge unlock relay 32b, and the lock actuator 20 is unlocked. As a result, the lock pin 21 of the lock actuator 20 moves to the unlock position UP so that the lock pin 21 does not protrude.

When the set time has elapsed after the lock actuator 20 is locked in operation S26, the lock controller 30 determines whether the unlock operation of the lock actuator 20 is normally performed (S27).

Looking specifically at step S27, if the set time has elapsed after the lock actuator 20 operates the lock, the lock controller 30 may detect the level of the current applied to the lock actuator 20. If the level of the detected current corresponds to the second set level, the lock pin 21 of the lock actuator 20 can be regarded as being in the unlocked position UP. Therefore, the lock controller 30 unlocks the lock actuator 20. It can be determined that the operation is normal, and if the detected current level does not correspond to the second set level, it can be considered that the lock pin 21 of the lock actuator 20 is not located at the unlock position UP, so that the lock controller 30 may determine that the unlocking operation of the lock actuator 20 is not normal. Here, the second set level may be set to a current level detected (feedback) by the lock actuator 20 when the lock pin 21 of the lock actuator 20 is located at the unlock position UP.

In the above-described step S27, when the lock controller 30 determines that the unlock operation of the lock actuator 20 is not normally performed, the lock controller 30 retries the unlock operation of the lock actuator 20. (S27-1).

In the above-described step S25, if it is determined that the cover 14 does not open the opening 12 of the housing 11 during the lock operation of the lock actuator 20, the set time elapses after the lock actuator 20 is locked. In one state, the lock controller 30 determines whether the lock operation of the lock actuator 20 is normally performed (S28).

Looking at step S28 in detail, the lock controller 30 may detect the level of the current applied to the lock actuator 20 in a state where the set time has elapsed after the lock actuator 20 is operated. If the level of the detected current corresponds to the first set level, the lock pin 21 of the lock actuator 20 can be regarded as being in the lock position LP, so that the lock controller 30 locks the lock actuator 20. It can be determined that the operation is normal, and the lock controller 21 can be considered that the lock pin 21 of the lock actuator 20 is not located at the lock position LP if the detected current level does not correspond to the first set level. 30 may determine that the lock operation of the lock actuator 20 is not normal. Here, the first set level may be set to a current level detected (feedback) by the lock actuator 20 when the lock pin 21 of the lock actuator 20 is located at the lock position LP.

In the above-described step S28, if the lock controller 30 determines that the lock pin 21 of the lock actuator 20 is not normally operated, the lock controller 30 retries the lock operation of the lock actuator 20 (RETRY). (S28-1).

By the fail-safety logic described above, the cover 14 opens the opening 12 of the housing 11 while the lock actuator 20 is locked while the cover 14 closes the opening 12 of the housing 11. The opening of the lock actuator 20 can prevent the lock pin 21 of the lock actuator 20 from moving to the lock position LP. When the cover 14 is opened, the lock actuator 20 is unlocked (ie, By maintaining the lock pin 21 in the unlocked position (UP), it is possible to prevent the closing of the cover 14, the electrical connection of the charging plug 15 and the charging receptacle 13, etc. becomes impossible.

FIG. 7 shows a detailed flowchart of the retry of the lock operation according to the step S5-1 of FIG. 5 and the retry of the lock operation according to the step S28-1 of FIG. 6.

The lock controller 30 transmits the lock signal to the lock actuator 20 via the charge lock relay 32a so that the lock actuator 20 operates during the predetermined lock operation time period (S31). For example, the lock operation time may be 1 second, and the lock operation time may be variously set according to the specification of the vehicle.

The lock controller 30 determines whether the lock operation of the lock actuator 20 is normally performed during the set lock operation time (S32).

In step S32, if the lock operation of the lock actuator 20 is not normal during the set lock operation time, the lock controller 30 operates the charge unlock relay 32b (S33). The unlock signal is transmitted to the lock actuator 20 through the charge unlock relay 32b, and the lock actuator 20 is unlocked for a predetermined unlock operation time peroid. For example, the unlock operation time may be 1 second, and the unlock operation time may be variously set according to the specification of the vehicle.

The lock controller 30 monitors whether the lock actuator 20 is unlocked during the set unlock operation time (S34).

During this monitoring, if unlock operation of the lock actuator 20 is normally performed before the unlock operation time has elapsed, the lock controller 30 immediately deactivates the charge unlock relay 32b and activates the charge lock relay 32a. At step S35, the step S32 is repeated.

In addition, if the unlocking operation of the lock actuator 20 is not normally performed until the unlocking operation time elapses, the lock controller 30 deactivates the charging unlocking relay 32b and operates the charging lock relay 32a (S35). ), And step S32 is repeated.

In the step S32, if the lock operation of the lock actuator 20 is normally performed during the set lock operation time, the lock controller 30 deactivates the charge lock relay 32a (S36).

FIG. 8 shows a detailed flowchart of the retry operation of the unlock operation according to the step S9-1 of FIG. 5 and the retry operation of the unlock operation according to the step S27-1 of FIG. 6.

The lock controller 30 transmits the unlock signal to the lock actuator 20 via the charge unlock relay 32b so that the lock actuator 20 is unlocked for a predetermined unlock operation time period (S41). For example, the unlock operation time may be 1 second, and the unlock operation time may be variously set according to the specification of the vehicle.

The lock controller 30 determines whether the unlock operation of the lock actuator 20 is normally performed during the set unlock operation time (S42).

In the step S42, when the unlocking operation of the lock actuator 20 is not normal when the set unlocking time elapses, the lock controller 30 operates the charge lock relay 32a (S43). The lock signal is transmitted to the lock actuator 20 through the charge lock relay 32a, and the lock actuator 20 operates for a predetermined lock operation time. For example, the lock operation time may be 1 second, and the lock operation time may be variously set according to the specification of the vehicle.

The lock controller 30 monitors whether the lock actuator 20 is locked during the set lock operation time (S44).

During this monitoring, if the lock actuator 20 is normally operated before the set lock operation time has elapsed, the lock controller 30 deactivates the charge lock relay 32a and operates the charge unlock relay 32b immediately. (S45), step S42 is repeated.

In addition, if the lock operation of the lock actuator 20 is not normally performed until the set lock operation time has elapsed, the lock controller 30 deactivates the charge lock relay 32a and operates the charge unlock relay 32b (S45). ), And step S42 is repeated.

In operation S42, when the unlock operation of the lock actuator 20 is normally performed during the set unlock operation time, the lock controller 30 deactivates the charging unlock relay 32b in operation S46.
