Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention.

Furthermore, the appearances of the terms "first," "second," and the like, if any, are used solely to distinguish one from another and are not to be construed as indicating or implying relative importance.

It should be noted that the features of the embodiments of the present invention may be combined with each other without conflict.

Currently, the most common vehicle starting process is: when a driver enters the vehicle, a starting key is inserted into the ignition lock, the vehicle is started by rotating to a START gear, or the vehicle is started by pressing a key starting switch; and then the hand brake is released, the gear is switched, and the vehicle is driven out of the parking space. This type of activation requires the driver to operate a one-touch activation switch or ignition lock to place the vehicle in a drivable, i.e., READY, state. The operation steps before driving are troublesome, and the requirements of the current vehicle using group on the comfort, the simplicity and the intellectualization of the vehicle are not met.

In order to overcome the defects of the prior art, the application provides the vehicle induction power-on method without the starting switch, the vehicle can be in a running state without operating a key starting switch or an ignition lock, the operation steps before driving are simplified, the convenience, the comfort and the intelligent feeling of a client are improved, and the advantages of the vehicle in market competition are improved.

The vehicle power-on management means that the vehicle power system is switched from an OFF state to a vehicle drivable state, namely a READY state. The OFF state is that the vehicle power is in OFF gear, the gear is in P gear, and the four doors and the back door are in a locking state. Referring to fig. 1, the present embodiment provides a method for vehicle inductive power up without a start switch, which mainly includes:

s100: receiving an unlocking signal of a vehicle; s200: controlling the electronic column lock 140 to unlock; s300: the control power supply 130 is placed in the ON gear; s400: requesting security authentication; if the safety certification request passes, judging whether the vehicle meets the driving condition; and if the vehicle meets the driving condition, controlling the vehicle to be in a drivable state. The process is a power-ON process of the vehicle, namely, the power supply 130 is switched from an OFF gear to an ON gear, the ACC relay and the IG relay are closed, and the vehicle is placed in a READY state.

In step S100, the unlocking signal includes a remote unlocking signal of the key fob 160, for example, when the key fob 160 is within a Radio Frequency (RF) authentication range around the vehicle, the user presses an unlocking button of the key fob 160. When the BCM (Body condrolmodule, the Body control module 110) receives the radio frequency signal sent by the smart key 160, the BCM and the smart key 160 perform identity authentication, and when the authentication is passed, the vehicle door is unlocked, and at this time, the vehicle door is in an openable state. If the identity authentication is not passed, the vehicle door is not unlocked and is in a locked state and cannot be opened.

Alternatively, the unlocking signal may be that the user triggers a micro switch of a front door handle of the vehicle and sends a click signal to the BCM to wake up the BCM when the key fob 160 is within a preset distance range from the vehicle. The micro switch can be of a capacitive type or a push-button type and is triggered by touching or pressing. The preset distance range from the vehicle may be a vehicle surrounding RF authentication range. That is, if the BCM receives the click signal of the door handle and senses the smart key 160, the BCM and the smart key 160 perform identity authentication, the authentication is passed, the door is unlocked, and the door is in an openable state. If the identity authentication is not passed, the vehicle door is not unlocked and is in a locked state and cannot be opened.

In the step S200, if the BCM receives a valid unlocking signal, that is, receives the unlocking signal and passes the identity authentication, the BCM controls the electronic column Lock 140(ESCL, electricalstreeeringcolumn Lock) to unlock, and controls the power supply 130 to be in the ON gear, at this time, the vehicle power supply 130 is switched from the OFF gear to the ON gear, and the ACC relay and the IG relay are closed, that is, the ACC power supply, the IG1 power supply, and the IG2 power supply may all operate.

Or the BCM receives an effective unlocking signal and detects the state of the vehicle door. If the door state is detected to be changed from closed to open, optionally, the BCM detects that the door state of the driving side is changed from closed to open, and a valid key 160 is sensed within a preset distance from the vehicle, the electronic pillar lock 140 is controlled to unlock. If the BCM does not detect that the door state is changed from closed to open, the brake state signal of the vehicle and the valid signal of the vehicle key 160 are acquired. If the brake is in a stepping-on state and a valid signal of the key 160 is detected, the BCM controls the electronic column lock 140 to unlock.

In step S300, after the electronic pillar lock 140 is successfully unlocked, the BCM control power supply 130 is turned ON. Alternatively, the power supply 130 may be turned ON by remote control. For example, a user logs in a valid account on a mobile device terminal APP such as a mobile phone, and sends a remote control instruction to the T-BOX170 through the APP. The T-BOX170 receives remote control commands to wake up the vehicle controller 150. After the vehicle control unit 150 is awakened by the T-BOX170, the vehicle is controlled to enter a remote control mode, and the vehicle body control module 110 is awakened. The vehicle body control module 110 obtains a power-on request of the T-BOX170 (TelematicBOX, vehicle-mounted computer) in real time, and performs communication authentication with the T-BOX170 after receiving the power-on request of the T-BOX 170. Optionally, in this embodiment, the BCM and the T-BOX170 perform communication authentication through a CAN (ConTroller Area NeTwork) bus. The vehicle body control module 110 engages the power supply 130 and the relay after the communication authentication is passed, and switches the power supply 130 from OFF to ON. At this time, the electronic pillar lock 140 is not unlocked, and the VCU (Vehicle controller 150) does not issue the security authentication and READY request. In this state, high and low voltages in the vehicle are all electrified, and electric devices in the vehicle can be normally used.

In the step S400, after the power supply 130 is switched from OFF to ON, the VCU sends a safety certification request to the BCM, and after the safety certification request passes, the VCU judges whether the vehicle meets the driving condition; and if the vehicle meets the driving condition, detecting whether the charging gun is in a connected state, and if the charging gun is not connected, controlling the vehicle to enter a READY state by the VCU, namely the vehicle is in a drivable state, and completing electrification.

If the full authentication request does not pass, the power supply 130 is placed in an ON gear so that the combination meter or the vehicle machine prompts fault information. At the moment, the remote control unlocking can be triggered again for safety certification until the vehicle is powered off. And if the charging gun is detected to be in a connected state, the vehicle is in a non-drivable state until the charging gun is detected to be in a non-connected state, and the vehicle is controlled to be in a drivable state.

It should be noted that after the vehicle is powered on, the shift is only valid when the brake signal is detected and the valid key 160 signal is detected. According to the vehicle induction power-on method without the starting switch, a driver does not need to operate an ignition lock or a one-key starting switch, after unlocking the door, the driver only needs to open the door at the driving side, the BCM host machine detects that the door at the driving side is turned on from off, and controls the vehicle high-voltage power supply 130 to be switched on after detecting that the valid and valid key 160 is possessed in a radio frequency authentication range, and the BCM host machine communicates with the vehicle controller 150 to control the vehicle to enter a vehicle drivable state. Or after the BCM host detects an effective unlocking signal, the BCM host controls the vehicle high-voltage power supply 130 to be switched on, and communicates with the vehicle control unit 150 to control the vehicle to enter a vehicle-drivable state. The driver can drive away from the parking space only by lightly stepping on the brake and switching the gears, so that the power-on step before driving is simplified, and the convenience, comfort and intelligent feeling of the client are improved.

If the valid key 160 is sensed according to the remote unlock signal acquired by the BCM in real time or within a radio frequency authentication range, for example, 1.2 m from the vehicle, and the click signal of the micro switch of the door handle of the driving side (i.e., the front door handle) is received, step S2 is performed, and otherwise, step S5 is performed.

Step S2: and judging whether the four doors have door opening actions. And (4) waking up the BCM host, unlocking the four doors, timing for a period of time, such as 30S, and judging whether the door state is in a state from closed to open according to the door opening and closing operation state signal acquired in real time in 30S, if so, executing step S3, otherwise, executing step S4.

Step S3: and judging whether the state of the door at the driving side is changed from closed to open. And judging whether the state of the driving side door is changed or not according to the vehicle door switch operation state signal acquired in real time, if so, executing step S8, otherwise, keeping the ignition state of the whole vehicle in a vehicle power-OFF state, namely OFF gear.

Step S4: and (5) locking the door for the second time within 30s without changing the state of the door. If the door state is not changed within 30s, secondary locking is carried out, four doors and a back door are locked, and then the BCM host machine is dormant.

Step S5: the BCM receives a brake signal. And judging whether the brake is pressed according to the brake state signal acquired in real time, if so, executing step S6, otherwise, executing step S7.

And judging whether the remote control requests to be powered ON or not according to the T-BOX170 power-ON instruction acquired in real time, if so, placing the vehicle power supply 130 in an ON gear, and not sending security authentication and READY requests by the VCU. Judging whether an RKE or PKE unlocking signal is received or not; if yes, the vehicle exits the remote control mode, and step S3 is executed; otherwise, the vehicle enters remote power-OFF, so that the ignition state of the whole vehicle is kept in the power-OFF state OFF gear of the vehicle.

Step S8 (not shown): it is determined whether the key 160 is within the low frequency antenna sensing range of the front door. If so, executing step S9, otherwise, enabling PKE or RKE locking to be effective, locking the whole vehicle, and keeping the ignition state of the whole vehicle in a vehicle power-OFF state OFF gear.

Step S9: and judging whether the ESCL unlocking is successful. And if the BCM is successful in unlocking the ESCL, executing the step S10, otherwise, enabling PKE or RKE locking to be effective, locking the whole vehicle, and keeping the ignition state of the whole vehicle in a power-OFF state OFF gear of the vehicle.

Step S10: the power supply 130 is set to the ON gear, and the BCM and the VCU perform security authentication. The ACC relay, the IG1 relay and the IG2 relay are closed, the vehicle power supply 130 is switched from an OFF gear to an ON gear, the VCU sends a safety certification request to the BCM host, if the certification is passed, the step S11 is executed, otherwise, the vehicle power supply 130 keeps the ON gear and is not READY, namely, the vehicle power supply is in a non-driving state, or power-OFF judgment is executed.

Step S11: the VCU makes a READY judgment. The VCU judges whether the entire vehicle has a fault, and if not, executes step S12, otherwise, detects whether the fault is recovered. If the failure is recovered, go to step S12; if the fault is not recovered, the vehicle power supply 130 keeps ON, no READY, and the combination meter or the vehicle machine prompts fault information.

Step S12: the VCU detects whether the charging gun is connected. If the charging gun is not connected, executing step S13; otherwise, detecting whether the charging gun is disconnected, if the charging gun is not disconnected, keeping the vehicle power supply 130 in an ON gear and not in READY; on the contrary, if the charging gun connection state is disconnected, step S13 is executed.

Step S13: and the vehicle READY finishes electrifying. The VCU sets the vehicle state to READY and enters a drivable state.

It is easy to understand that if the vehicle needs to be powered OFF, the power supply 130 is in an OFF state and the BCM host is in a sleep state by one key power-OFF through a virtual switch on a console in the vehicle. And executing the step S6 until the BCM receives the brake signal.

In this embodiment, after receiving the unlocking signal, the BCM detects whether the door of the driving side is in the closed state or the open state, and authenticates the door with the smart key 160, that is, after detecting the valid key 160 within the preset distance, the ESCL electronic pillar lock 140 is successfully unlocked, and the power supply 130 is placed in the ON position. The VCU initiates safety authentication and places the vehicle in a READY state to realize electrification. The power-on step before the operation of the driver is simplified, the operation of a one-key starting switch or an ignition lock is omitted, the power-on method is quicker and more convenient, and the convenience, the comfort and the intelligent feeling of the user are improved.

Referring to fig. 5, optionally, the vehicle induction power-on system 100 without the start switch further includes a door state detection unit 180, and the door state detection unit 180 is in communication connection with the BCM. After the BCM receives a valid unlocking signal, the door state detecting unit 180 detects that the door state of the driving side is switched from off to ON, and the smart key 160 is in the sensing range of the BCM, the BCM controls the ESCL to unlock, and the power supply 130 is placed in the ON gear. Or the BCM detects that the brake is in a stepping-ON state and detects that the vehicle is provided with a valid signal of the intelligent key 160, the BCM controls the ESCL to unlock, and the power supply 130 is placed in an ON gear. At this time, high and low voltage devices of the vehicle, such as a switch, an air conditioner and the like, can work normally.

The BCM controls the ESCL to unlock, and after the power supply 130 is set to be in the ON gear, the VCU and the BCM perform safety certification. Optionally, the VCU sends a security authentication request to the BCM, and after the security authentication request passes, the VCU detects whether the vehicle meets the driving condition, that is, determines whether the vehicle has a fault. If the vehicle is not in fault, the VCU places the vehicle in a READY state. If the vehicle has a fault, the power supply 130 is placed in an ON gear, the vehicle does not enter a READY state, and the combination meter or the vehicle machine can prompt fault information. Further, if the VCU detects that the vehicle is not in fault, the VCU detects whether the charging gun is connected. If the charging gun is not connected, the vehicle READY is powered on; if the gun connection is not disconnected, the vehicle power supply 130 remains ON and is not READY. It should be noted that, the vehicle is in READY state, the driver needs to step on the brake, and the shift is only effective after detecting the valid key 160 signal.

Optionally, the vehicle inductive power-on system 100 without a start switch can also perform remote control power-on. A user logs in a valid account on a mobile equipment terminal APP such as a mobile phone and the like, and sends a remote control instruction to the T-BOX170 through the APP. The T-BOX170 is respectively in communication connection with the vehicle body control module 110 and the vehicle control unit 150; the T-BOX170 is configured to receive a remote control command to wake up the vehicle controller 150. The vehicle control unit 150 is also used to control the vehicle to enter a remote control mode after being awakened by the T-BOX170 and to awaken the vehicle body control module 110. The vehicle body control module 110 is configured to obtain a power-ON request of the T-BOX170 in real time, perform communication authentication with the T-BOX170 after receiving the power-ON request of the T-BOX170, and the vehicle body control module 110 is further configured to pull a relay of the power supply 130 after the communication authentication is passed, and switch the power supply 130 from OFF to ON. At this point, the electronic pillar lock 140 is not unlocked and the VCU does not issue security authentication and READY requests. In this state, high and low voltages in the vehicle are all electrified, and electric devices in the vehicle can be normally used.

After the driver unlocks the vehicle door, only the vehicle door at the driving side needs to be opened, the BCM host detects that the vehicle door at the driving side is closed to be opened, and detects that the valid key 160 exists in the valid range of the key 160; or more simply, after the BCM host detects the effective unlocking signal, the BCM host directly controls the vehicle high-voltage power supply 130 to be switched on, and communicates with the vehicle control unit 150 to control the vehicle to enter the vehicle drivable state. The driver can drive off the parking space only by lightly stepping on the brake and switching the gears, thereby simplifying the operation steps of the driver.

In summary, the vehicle inductive powering method without the start switch and the system thereof provided by the embodiments of the present invention have the following beneficial effects:

according to the vehicle induction power-on method without the starting switch, manual operation of the one-key starting switch or the ignition lock is not needed, the power-on operation steps before driving are simplified, and a driver can experience more convenient, comfortable and intelligent feeling when using the vehicle.

According to the vehicle induction power-on system 100 without the starting switch, provided by the embodiment of the invention, the use of an ignition lock and a one-key starting switch is cancelled, the power-on management of the vehicle power supply 130 is realized by detecting signals such as a driving side door state signal and a key 160 signal, and the number of components of the vehicle power supply 130 management system is reduced, so that unnecessary vehicle power-on steps of a user are simplified, the convenience feeling of the user is improved, and the cost of the whole vehicle is reduced.

The above description is only for the specific embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention are included in the scope of the present invention.
