The implementation scene of the method for controlling the vehicle by the intelligent key comprises the intelligent key and a lifting mechanism arranged in the vehicle. Among them, the elevating mechanism may be provided around a Head Unit System (HUT) in the vehicle. The intelligent key is placed on elevating system, and is fixed through magnetism the mode with elevating system, and under fixed state, intelligent key and elevating system interact through 4 metal contact structures, and wherein, two metal contacts are used for elevating system to charge for intelligent key, and two metal contacts are used for data communication between intelligent key and the elevating system.
Fig. 1 is a flowchart of an implementation of a method for controlling a vehicle by using a smart key according to an embodiment of the present invention, which is applied to a smart key, and is detailed as follows:
When the intelligent key is not placed on the lifting mechanism, the lifting mechanism keeps in a lifting state, the upper surface of the lifting mechanism is flush with the inner decoration of the whole automobile, and the lifting mechanism is prevented from being damaged due to mistaken collision in the lifting state.
When intelligent key put into elevating system on, intelligent key is connected with elevating system, and is optional, can inhale fixed connection through magnetism between intelligent key and the elevating system, and after intelligent key and elevating system accomplished the communication authentication, communication was carried out. At the moment, the intelligent key can automatically send a descending instruction to the lifting mechanism, so that the lifting mechanism executes descending operation, after the intelligent key descends in place, namely when the lifting mechanism is in a descending state, the upper surface of the intelligent key is flush with the interior of the whole automobile, and the intelligent key is prevented from being mistakenly touched and then disconnected with the lifting mechanism.
And 102, receiving the engine state sent by the lifting mechanism, and displaying a corresponding interface according to the engine state.
When the lifting mechanism is in a descending state, the engine state CAN be acquired through the CAN bus, and the acquired engine state is sent to the intelligent key in real time.
The intelligent key is provided with a display screen, and the display screen can display a corresponding interface according to the state of the engine. When the lifting mechanism is in a descending stable state, receiving an engine state sent by the lifting mechanism, and acquiring the engine state by the lifting mechanism through a CAN bus at the moment, wherein the engine state comprises a starting state and a flameout state; when the engine state is a flameout state, displaying an interface comprising an opening identifier; and when the engine state is the starting state, displaying an interface comprising a flameout mark.
As shown in fig. 2, the interface of the opening flag may be an interface including a START word indicating opening, and as shown in fig. 3, the interface of the misfire flag may be an interface including a STOP word indicating stopping.
And 103, receiving a first trigger operation of a user on the interface, generating a corresponding operation instruction for starting or extinguishing the engine, and sending the operation instruction to the lifting mechanism, so that the lifting mechanism CAN forward the operation instruction to a corresponding controller through the CAN bus to execute the operation for starting or extinguishing the engine.
When the interface of the START word or the interface of the STOP word is displayed on the smart key, the user can perform the engine START or STOP operation by clicking the START word or the STOP word at one time.
In an embodiment, receiving a first trigger operation of a user on an interface, and generating a corresponding operation instruction may include: receiving a first trigger operation of a user on an interface comprising an opening identifier, and generating a starting instruction; or receiving a first trigger operation of a user on an interface comprising a flameout identifier, and generating a flameout instruction.
That is, when the smart key receives one-time clicking operation of a user on an interface including an opening identifier, a starting instruction is generated and sent to the lifting mechanism, the lifting mechanism is sent to a corresponding controller, such as an engine controller, through a CAN bus, and then the engine is controlled to execute the engine starting operation. It should be noted that when the interface including the turn-on flag is displayed on the smart key, the engine start operation may also be performed by the vehicle one-touch start switch.
When the intelligent key receives one-time clicking operation of a user on an interface comprising a flameout mark, a flameout instruction is generated and sent to the lifting mechanism, the lifting mechanism is sent to a corresponding controller, such as an engine controller, through a CAN bus, and then the engine is controlled to execute the flameout operation of the engine. It should be noted that when the interface including the misfire identification is displayed on the smart key, the engine misfire operation can also be performed by the vehicle one-touch start switch.
When the intelligent key detects that the engine is changed into a flameout state from a starting state, the intelligent key indicates that a driver wants to leave the vehicle, so that the intelligent key sends a lifting execution to the lifting mechanism, the lifting mechanism executes a lifting instruction, and in the lifting state of the lifting mechanism, the upper surface of the lifting mechanism is flush with the inner decoration of the whole vehicle, so that the driver can take away the intelligent key on the lifting mechanism.

In one embodiment, when a second trigger operation of the user on the current interface is received, an operation instruction opposite to the current state of the lifting mechanism is generated.
Specifically, when the lifting mechanism is in a descending state, the user can perform double-click operation on the current interface of the intelligent key, and the intelligent key receives second trigger operation of the user on the current interface, generates a lifting instruction and sends the lifting instruction to the lifting mechanism. The second trigger operation here refers to an operation of double-clicking the smart key.
And when the lifting mechanism is in a lifting state, receiving a second trigger operation of a user on the current interface, generating a descending instruction and sending the descending instruction to the lifting mechanism.
And after receiving the lifting command or the descending command sent by the intelligent key, the lifting mechanism executes corresponding lifting or descending operation.
According to the embodiment of the invention, when the connection between the intelligent key and the lifting mechanism arranged on the vehicle is detected, a descending instruction is automatically sent to the lifting mechanism, so that the lifting mechanism can conveniently execute descending operation, and the intelligent key is protected from being mistakenly collided and falling; the method comprises the steps of receiving an engine state sent by a lifting mechanism, displaying a corresponding interface according to the engine state, receiving a first trigger operation of a user on the interface, generating a corresponding operation instruction for starting or extinguishing the engine, and sending the operation instruction to the lifting mechanism, so that the lifting mechanism forwards the operation instruction to a corresponding controller through a CAN bus to execute the operation for starting or extinguishing the engine, and therefore, the vehicle CAN be accurately started or extinguished at one time through the trigger operation of the display interface on the intelligent key, and the operation is simple. The intelligent key displays an interface comprising an extinguishing mark when the engine state is the starting state, displays the interface comprising the starting mark when the engine state is the extinguishing state, and only displays a corresponding interface on the intelligent key, so that the problem that a user cannot accurately trigger the mark determined by operation once because a liquid crystal display screen of the key comprises a plurality of marks in the prior art is solved.
Fig. 4 is another method for controlling a vehicle by using a smart key according to an embodiment of the present invention, where an execution subject is a lifting mechanism disposed on the vehicle, which is described in detail below.
The lifting mechanism can be in a lifting state and a descending state, when the intelligent key is not placed on the lifting mechanism, the lifting mechanism is in the lifting state, the upper surface of the lifting mechanism is flush with the inner decoration of the whole automobile, and the lifting mechanism is prevented from being damaged due to mistaken collision in the lifting state.
After elevating system detected smart key and connected with it, for example magnetism inhale fixed connection, can receive the decline instruction that smart key sent this moment, can also according to the automatic decline instruction that generates of testing result. When the lifting mechanism detects, the automatic induction can be carried out through the metal contact on the lifting mechanism, and after the metal contact attached to the intelligent key is induced, the intelligent key is determined to be connected with the lifting mechanism.
When the lifting mechanism executes the descending operation, after the intelligent key descends in place, the upper surface of the intelligent key is flush with the interior of the whole vehicle, namely, the descending height of the lifting mechanism is consistent with the thickness of the intelligent key, so that the intelligent key is prevented from being disconnected with the lifting mechanism after being mistakenly collided.
In one embodiment, receiving a drop command sent by a smart key comprises: and receiving a descending instruction sent by the intelligent key through the UART serial port. The communication mode between the intelligent key and the lifting mechanism is UART serial port communication.
The lifting mechanism can also receive a rising instruction sent by the intelligent key through the UART serial port, the rising operation is executed according to the rising instruction, the upper surface of the lifting mechanism is flush with the interior of the whole vehicle, the intelligent key is placed on the lifting mechanism, and a user can conveniently take the intelligent key.
And 402, acquiring the current engine state, transmitting the current engine state to the intelligent key in real time, receiving an operation instruction sent by the intelligent key, and transmitting the operation instruction to a corresponding controller through the CAN bus to execute the operation of starting or stopping the engine.
After the lifting mechanism descends in place, the lifting mechanism CAN be communicated with each controller of the vehicle through the CAN bus, the current engine state CAN be obtained through the CAN bus, the engine state comprises a starting state and a flameout state, and then the engine state is sent to the intelligent key, so that the intelligent key CAN display a corresponding interface according to the engine state.
The intelligent key and the lifting mechanism are fixed in a magnetic attraction mode, so that the lifting mechanism and the intelligent key are in a descending state together, or the intelligent key falls down or the intelligent key and the lifting mechanism are disconnected from the magnetic attraction mode and fixed due to vehicle bump or manual operation in the descending/lifting process. When the lifting mechanism detects that the intelligent key and the lifting mechanism are disconnected from magnetic attraction and fixed, communication connection is interrupted, lifting operation is executed, a driver is reminded that the intelligent key and the lifting mechanism are disconnected from magnetic attraction and fixed at present, and the driver can place the intelligent key on the lifting mechanism or adjust the position of the intelligent key again, so that communication connection is reestablished between the intelligent key and the lifting mechanism.
In order to reduce the falling probability of the smart key in the descending process, the ascending process and the descending state of the lifting mechanism, at least two limiting cards can be arranged at the edge position of the lifting mechanism, as shown in fig. 5, when the smart key is not connected with the lifting mechanism, the at least two limiting cards are in a contraction state, namely, are contracted at the edge of the lifting mechanism. In the present embodiment, the shape of the lifting mechanism is not limited, and may be a regular pattern such as a circle or a square, or may be an irregular shape similar to a smart key, and a circle is illustrated in fig. 5 as an example. When the connection between the intelligent key and the lifting mechanism is detected, the subsequent lifting mechanism can carry the intelligent key to perform ascending or descending operation, so that the at least two limiting cards can be controlled to extend, and the intelligent key on the lifting mechanism can be clamped. Here, for pleasing to the eye, the limit card can block the edge of smart key, and the magnetism between smart key and the elevating system is inhaled fixedly in addition, can greatly reduced smart key's the probability that drops.
The number of spacing card can be two, but adopt two spacing cards to be difficult to prevent that naughty child from detaining the smart key on purpose, consequently can set up the quantity of spacing card and be three or four etc..
When a jam is encountered during the execution of the lowering operation or the raising operation, the state before the current operation is restored. Because the resistance induction sensor is arranged on the lifting mechanism, the resistance threshold value of the lifting mechanism in the lifting process is a fixed value, when the resistance identified by the resistance induction sensor exceeds the resistance threshold value, the lifting mechanism is determined to be in a state before operation when the descending operation or the lifting operation is executed, for example, the lifting mechanism is recovered to the lifting state when the descending operation is currently executed, and the lifting mechanism is recovered to the descending state when the lifting operation is currently executed, so that the damage of the lifting mechanism caused by the continuous operation of the lifting mechanism is prevented.
According to the embodiment of the invention, the corresponding descending or ascending operation is executed according to the descending or ascending instruction of the intelligent key, the acquired engine state can be forwarded to the intelligent key in real time, the operation instruction sent by the intelligent key according to the engine state is received, and the operation instruction is forwarded to the corresponding controller to execute the starting or extinguishing operation of the engine, so that the vehicle can be started or extinguished quickly and accurately, and the operation is simple. When meeting the jamming in the lifting mechanism executing lifting process, the lifting mechanism recovers to the state before operation, and prevents the lifting mechanism from further executing operation damage.
Referring to fig. 6(1), in the method for controlling a vehicle using a smart key, when the smart key is not placed on the lifting mechanism, the lifting mechanism is kept in a lifted state, and the upper surface of the lifting mechanism is flush with the interior of the whole vehicle.
When the intelligent key is placed on the lifting mechanism, the intelligent key and the lifting mechanism are fixed through magnetic attraction, after communication authentication is completed, the intelligent key automatically sends a descending instruction to the lifting mechanism, and after the lifting mechanism receives the descending instruction, descending operation is executed. After the lifting mechanism descends in place, the lifting mechanism is in a descending state, and the upper surface of the intelligent key is flush with the inner decoration of the whole vehicle.
The lifting mechanism obtains the state of the engine through the CAN bus and forwards the state to the intelligent key in real time, and the intelligent key displays a corresponding interface according to the state of the engine.
The intelligent key receives a first trigger operation of a user on an interface, generates a corresponding engine operation instruction and sends the engine operation instruction to the lifting mechanism, and the lifting mechanism sends the operation instruction to a corresponding controller through a CAN bus so that the controller CAN execute the engine operation.
When the intelligent key detects that the engine is in a flameout state, a lifting instruction is sent to the lifting mechanism, the lifting mechanism executes lifting operation according to the lifting instruction, the upper surface of the lifting mechanism is flush with the interior of the whole vehicle, and the intelligent key is arranged on the lifting mechanism and is convenient for a driver to take down.
See fig. 6(2) for a method of controlling a vehicle by the smart key.
When the lifting mechanism and the intelligent key are in a descending state, the intelligent key receives a second trigger operation of a user on the current interface, such as a double-click operation, sends a lifting instruction to the lifting mechanism, and the lifting mechanism executes the lifting operation after receiving the lifting instruction.
