Description

Technical Field

[0001] The present invention relates to the technical field of engine starting and power generation control, and particularly relates to a motorcycle engine starting and power generation control device with user identity recognition. Background Art

[0002] Please refer to Figure 1 and Figure 2 As shown, the existing motorcycle system consists of an engine assembly 1, a starter / generator 2, a battery 3, a lock body assembly 4, and an engine starting and power generation control device 5. At the same time, a mechanical key control device (not shown in the figure) is also installed on the motorcycle. Currently, although both the engine starting and power generation control device 5 and the mechanical key control device are installed on the motorcycle, they are not related. The former is used to complete the control of dragging the engine to start and charging after the engine starts, and the latter is used to control the unlocking of the lock body assembly 4 and the power supply of the whole vehicle by inserting a mechanical key by the user.

[0003] The inventors of the present application have found through research that, on the one hand, the existing mechanical key has the defect that it can be copied and used to steal the vehicle, or the thief uses illegal means to violently damage the lock body or wiring harness, and after forcibly hard-wiring to energize the motorcycle, the vehicle engine can also be started and powered, and then the vehicle can be stolen, reducing the anti-theft performance of the whole vehicle; on the other hand, both the engine starting and power generation control device 5 and the mechanical key control device are installed on the motorcycle, and more installation space needs to be reserved during the design of the whole vehicle, increasing the difficulty of vehicle layout and the weight of the vehicle itself. Summary of the Invention

[0004] Aiming at the technical problems in the existing motorcycle system that thieves use illegal means to violently damage the lock body or wiring harness, forcibly hard-wire to energize the motorcycle to complete the starting and power generation of the vehicle engine, and then complete the theft of the vehicle, and in addition, both the engine starting and power generation control device and the mechanical key control device are installed on the motorcycle, and more installation space needs to be reserved during the design of the whole vehicle, increasing the difficulty of vehicle layout and the weight of the vehicle itself, the present invention provides a motorcycle engine starting and power generation control device with user identity recognition.

[0005] To solve the above technical problems, the present invention adopts the following technical solutions:

[0006] A motorcycle engine starting and power generation control device with user identity recognition, comprising a control module and a starting and power generation driving module. The device further includes a user identity recognition module, which includes a signal detection unit, a wireless communication unit, and a driving unit. The signal detection unit is used to detect an unlocking signal when the user carries an electronic key or remotely operates the unlocking switch in the vehicle lock body assembly with a wireless portable device. The wireless communication unit is used to, when the signal detection unit detects an unlocking signal, identify whether there is a legal electronic key authenticated with the vehicle or a wireless portable device after registration and pairing around the vehicle through wireless signals. The driving unit is used to drive the lock body assembly to complete unlocking when the wireless communication unit identifies a legal electronic key or a wireless portable device after registration and pairing, so as to allow the user to operate the vehicle to unlock and power on. The control module is used to receive the legal signal transmitted when the wireless communication unit identifies a legal electronic key or a wireless portable device after registration and pairing. The starting and power generation driving module is used to allow the driving of the starting and power generation machine when the control module receives the legal signal and the user has operated the starting switch in the motorcycle handlebar, so that the starting and power generation machine drags the engine to run to achieve starting.

[0007] Compared with the prior art, the motorcycle engine starting and power generation control device with user identity recognition provided by the present invention can determine whether to start the engine by detecting whether the user identity is legal by adding a user identity recognition module with a user identity detection and recognition function. That is, only when the user carries a legal electronic key authenticated with the vehicle or a wireless portable device after registration and pairing, such as a mobile phone, a bracelet, a watch, a radio frequency card, etc., will the action of dragging the engine to start and generate power be executed. If the vehicle is forced to be powered on by illegal means and the device does not recognize the legal user identity, it will enter the protection mode to prohibit the engine from starting and generating power, so as to achieve the purpose of anti-theft and reduce the property loss of users. Compared with the traditional mechanical key that only controls the vehicle power supply system, the anti-theft performance is better. At the same time, using wireless identity recognition to control the starting of the generator fundamentally avoids the defects that the mechanical key is easy to be copied and the vehicle is stolen by violent hard wiring compared with using a mechanical key to control the vehicle power supply. In addition, this device can remove the separately added anti-theft device or keyless unlocking controller in the existing vehicle, thus greatly simplifying the vehicle electrical system, facilitating the vehicle space layout and reducing the vehicle weight.

[0008] Further, the wireless communication unit includes a Bluetooth transceiver, which is used to perform Bluetooth communication with the electronic key or wireless portable device carried by the user to confirm the user identity, and only when the received Bluetooth signal strength is used to identify that the user's position from the vehicle is within a preset distance is it considered truly legal.

[0009] Further, the wireless communication unit includes a high-frequency communication circuit, which is used to receive and identify a pre-paired key transmitted after a user presses an unlocking button on a carried electronic key or a wireless portable device.

[0010] Further, the wireless communication unit further includes a low-frequency communication circuit, which is used to send a low-frequency signal carrying an ID number to identify whether there is an authenticated electronic key or wireless portable device around the vehicle. The high-frequency communication circuit is used to, after receiving the low-frequency signal sent by the low-frequency communication circuit if there is an authenticated electronic key or wireless portable device, identify whether the user's identity is legal according to the authenticated encrypted data replied by the high-frequency communication through the authenticated electronic key or wireless portable device.

[0011] Further, the signal detection unit includes an anti-backflow protection circuit, a waterproof misoperation prevention circuit, and a signal conversion and filtering circuit connected in sequence. The anti-backflow protection circuit is used to prevent external surge voltage from flowing back and damaging the internal waterproof misoperation prevention circuit and signal conversion and filtering circuit. The waterproof misoperation prevention circuit is used to prevent the situation of misoperation after the external switch K1 gets water. The signal conversion and filtering circuit is used to complete the unlocking signal conversion and absorb the noise interference in the circuit to prevent detecting false signals.

[0012] Further, the driving unit includes an intelligent high-side switch chip U1, a freewheeling protection diode D2, and anti-backflow diodes D3 and D5. The positive electrode of the freewheeling protection diode D2 is connected to the OUT0 pin of the intelligent high-side switch chip U1 and the lock solenoid valve, and the negative electrode is connected to the Vss pin of the intelligent high-side switch chip U1. The positive electrodes of the anti-backflow diodes D3 and D5 are connected to the OUT1 pin of the intelligent high-side switch chip U1, and the negative electrodes are respectively connected to the right turn signal lamp and the left turn signal lamp. The input signals of the IN0 and IN1 pins of the intelligent high-side switch chip U1 respectively control the two-way outputs of the OUT0 and OUT1 pins. The output of the OUT0 pin controls the lock body assembly to perform unlocking control, and the output of the OUT1 pin controls the left and right turn signal lamps to perform car-finding indication.

Detailed implementation manners

[0019] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below with reference to specific illustrations.

[0020] In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0021] Please refer to Figure 3As shown in the figure, the present invention provides a motorcycle engine starting and power generation control device with user identity recognition, including a control module 10 and a starting and power generation driving module 20. The device further includes a user identity recognition module 30, which includes a signal detection unit 301, a wireless communication unit 302, and a driving unit 303. The signal detection unit 301 is used to detect an unlocking signal when the user carries an electronic key or remotely operates the unlocking switch in the vehicle lock body assembly with a wireless portable device. The wireless communication unit 302 is used to identify whether there is a legal electronic key or a wireless portable device registered and paired with the vehicle around the vehicle through wireless signals when the signal detection unit 301 detects the unlocking signal (when the user approaches the vehicle and presses the unlocking switch). The driving unit 303 is used to drive the lock body assembly to complete unlocking when the wireless communication unit 302 identifies a legal electronic key or a wireless portable device registered and paired with the vehicle, so as to allow the user to operate the vehicle to unlock and power on. The control module 10 is used to receive the legal signal transmitted when the wireless communication unit 302 identifies a legal electronic key or a wireless portable device registered and paired with the vehicle, that is, the wireless communication unit 302 transmits the legal signal to the control module 10 simultaneously after identifying a legal electronic key or a wireless portable device registered and paired with the vehicle. The starting and power generation driving module 20 is used to allow the driving of the starting and power generation machine when the control module 10 receives the legal signal and the user has operated the starting switch in the motorcycle handlebar, and let the starting and power generation machine drive the engine to run to achieve starting.

[0022] Compared with the prior art, the motorcycle engine starting and power generation control device with user identity recognition provided by the present invention can determine whether to start the engine by detecting whether the user identity is legal by adding a user identity recognition module with user identity detection and recognition functions. That is, only when the user carries a legal electronic key or a wireless portable device registered and paired with the vehicle, such as a mobile phone, a smart bracelet, a smart watch, a radio frequency card, etc., will the action of dragging the engine to start and generate power be executed. If the vehicle is forced to be powered on by illegal means and the device does not recognize the legal user identity, it will enter the protection mode to prohibit the engine from starting and generating power to achieve the purpose of anti-theft and reduce the property loss of users. Compared with the traditional mechanical key that only controls the vehicle power supply system, the anti-theft performance is better. At the same time, using wireless identity recognition to control the starting of the generator fundamentally avoids the defects that the mechanical key is easy to be copied and the vehicle is stolen by violent hard wiring compared with using the mechanical key to control the vehicle power supply. In addition, this device can remove the separately added anti-theft device or keyless unlocking controller in the existing vehicle, thus greatly simplifying the vehicle electrical system, facilitating the vehicle space layout and reducing the vehicle weight.

[0023] As a specific embodiment, the wireless communication unit 302 includes a Bluetooth transceiver. The specific composition of the Bluetooth transceiver is well-known to those skilled in the art. The Bluetooth transceiver is used to perform Bluetooth communication with an electronic key or a wireless portable device carried by the user to confirm the user's identity, and uses the received Bluetooth signal strength to identify that the user is at a position within a preset distance from the vehicle before it is considered truly legitimate. That is, first, Bluetooth communication is used to confirm whether the user's identity is legal, and then the Bluetooth signal strength is used to identify that the user is at a position within a preset distance from the vehicle (the Bluetooth signal strength is inversely proportional to the position of the user from the vehicle) before it is considered truly legitimate, so as to comprehensively determine whether to respond to the user's operation.

[0024] As another specific embodiment, the wireless communication unit 302 includes a high-frequency communication circuit. The high-frequency communication circuit can be specifically implemented using existing technologies. The high-frequency communication circuit is used to receive and identify a pre-paired key transmitted after the user presses an unlock button on the electronic key or wireless portable device carried. That is, after the user presses the unlock button on the electronic key or wireless portable device carried, the pre-paired key is transmitted to the high-frequency communication circuit of the wireless communication unit 302 for identification. After successful identification, the entire vehicle is unlocked by controlling the drive unit 303, so as to implement the remote control unlocking function.

[0025] As yet another specific embodiment, the wireless communication unit 302 further includes a low-frequency communication circuit, that is, the wireless communication unit 302 includes both a high-frequency communication circuit and a low-frequency communication circuit at the same time. The low-frequency communication circuit can be specifically implemented using existing technologies. The low-frequency communication circuit is used to send a low-frequency signal carrying an ID number to identify whether there is an authenticated electronic key or wireless portable device around the vehicle. The high-frequency communication circuit is used to, after receiving the low-frequency signal sent by the low-frequency communication circuit if there is an authenticated electronic key or wireless portable device, identify whether the user's identity is legal according to the authenticated encrypted data replied by the authenticated electronic key or wireless portable device through high-frequency communication. Specifically, when the low-frequency communication circuit identifies that there is an authenticated electronic key or wireless portable device around the vehicle, after receiving the low-frequency signal, the authenticated electronic key or wireless portable device will reply to the high-frequency communication circuit through high-frequency communication, and the high-frequency communication circuit will then identify whether the user's identity is legal according to the replied authenticated encrypted data, and finally determine whether to respond to the unlock operation, thereby realizing the close-range automatic induction unlocking. Compared with the technical solutions in the above embodiments, in this embodiment, a new low-frequency communication circuit is added to identify the user's position, while the role of the high-frequency communication circuit is the same.

[0026] As a specific embodiment, please refer to Figure 4As shown, the signal detection unit 301 includes an anti-backflow protection circuit, a waterproof misoperation prevention circuit, and a signal conversion and filtering circuit connected in sequence. The anti-backflow protection circuit is used to prevent external surge voltage from flowing back and damaging the internal waterproof misoperation prevention circuit and signal conversion and filtering circuit. Specifically, the anti-backflow protection circuit is composed of diode D4 in the figure; the waterproof misoperation prevention circuit is used to prevent the situation of misoperation after the external switch K1 gets water. Specifically, the waterproof misoperation prevention circuit is jointly composed of transistor Q1, resistors R2, R3, and R6 in the figure. When the contacts of the external switch K1 get water, an equivalent resistance Rx is formed. Generally, the resistance value of water > 600 ohms. By designing the voltage-dividing resistance values of resistors R2, R3, and R6, it can be set that transistor Q1 conducts only when the water resistance of the switch < 600 ohms. Because the water resistance after the switch gets water is > 600 ohms, and when the switch K1 is normally connected, the switch resistance < 10 ohms. At this time, through the voltage division of resistors R2, R3, and R6, transistor Q1 can be normally turned on, so as to achieve the situation of preventing misoperation after the external switch K1 gets water; the signal conversion and filtering circuit is used to complete the unlocking signal conversion and absorb the noise interference in the circuit to prevent detecting false signals. Specifically, the signal conversion and filtering circuit is jointly composed of resistors R9 and R10 and capacitors C2 and C5 in the figure. Resistors R9 and R10 are used to complete the unlocking signal conversion, and capacitors C2 and C5 are used to absorb the noise interference in the circuit.

[0027] As a specific embodiment, please refer to Figure 5 As shown, the driving unit 303 includes an intelligent high-side switch chip U1, a freewheeling protection diode D2, and anti-backflow diodes D3 and D5. The intelligent high-side switch chip U1 can be specifically implemented by using an existing chip with the model of HD70802QASSOP14P. The positive electrode of the freewheeling protection diode D2 is connected to the OUT0 pin of the intelligent high-side switch chip U1 and the lock solenoid valve, and the negative electrode is connected to the Vss pin of the intelligent high-side switch chip U1; the positive electrodes of the anti-backflow diodes D3 and D5 are connected to the OUT1 pin of the intelligent high-side switch chip U1, and the negative electrodes are respectively connected to the right turn signal lamp and the left turn signal lamp; the input signals of the IN0 and IN1 pins of the intelligent high-side switch chip U1 respectively control the two-way outputs of the OUT0 and OUT1 pins. The OUT0 pin outputs to control the lock body assembly to perform the unlocking control, and the OUT1 pin outputs to control the left and right turn signal lamps to perform the car-finding indication.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limitations. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
