[0032] Figure 1 The structural diagram of a cruise control system provided by an embodiment of the present application is exemplarily shown. Figure 1As shown, the system includes a cruise control unit 100, an ECU 101, an OBD interface 102, and a throttle handle 103; wherein the cruise control unit 100 is connected to the ECU 101 via a first connection line, connected to the throttle handle 103 via a second connection line, and connected to the OBD interface 102 via a third connection line; the ECU 101 is respectively connected to the OBD interface 102 and the speed control button 104. It should be noted that the ECU 101, the OBD interface 102, the throttle handle 103, and the speed control button 104 already exist when the motorcycle suitable for the cruise control system leaves the factory.

[0033] In some embodiments, the first connecting wire is a plug-in type connecting wire, and the second connecting wire and the third connecting wire are plug-in type connecting wires. Such simple plug-in type connecting wires are connected to the OBD interface 102 and the throttle handle 103, and the plug-in type connecting wires are connected to the ECU 101, without the need for a complicated installation process.

[0034] In some embodiments, the speed adjustment button 104 can be an original button of the motorcycle, which is a button that comes with the motorcycle when it leaves the factory, rather than an added or optional button, nor a button obtained by replacing the switch assembly; after the original button is used as a speed adjustment button, it still has the function of the original button when cruise control is not in progress or cruise control is exited; and the original button can also maintain the original connection state as a speed adjustment button, without the need to be connected to the cruise control unit. By using the existing original button of the motorcycle for operation, there is no need to add other control panels, thereby reducing the hardware cost of realizing the cruise control function.

[0035] In some embodiments, the cruise control unit 100 is used to monitor the operating data of the motorcycle through the OBD interface 102 in response to turning on the cruise control function, and output a speed control signal for changing the target cruise value to the ECU 101 based on the operating data, thereby monitoring the operating data of the motorcycle in real time, so as to control the throttle output based on this and maintain the cruise control state.

[0036] In some embodiments, the cruise control unit is specifically configured to:

[0037] When the target speed value adjusted by the speed control button 104 according to the speed control signal is greater than the minimum speed value, the cruise control function is maintained according to the adjusted target speed value; or when the adjusted target speed value is less than or equal to the minimum speed value, the cruise control function is released to improve the safety during the cruise control process.

[0038] In some embodiments, the cruise control unit 100 is further used to send a regulating voltage for maintaining the vehicle speed of the changed target cruise value to the ECU 101 based on the operation data, so as to maintain the subsequent cruise control state.

[0039] In some embodiments, the operating data may include at least one of the speed, the speed regulation signal, and the automatic release signal: wherein the automatic release signal includes any one of the communication abnormality detection, the minimum speed value, the braking signal, the power mode switching signal, and the motorcycle manual gear shifting behavior signal.

[0040] In some embodiments, the cruise control unit 100 is further configured to execute a cruise control function release operation in response to obtaining the above-mentioned automatic release signal, so as to improve the safety of the overall cruise control process.

[0041] In some embodiments, the cruise control unit 100 is further configured to take over the throttle handle 103 and monitor the voltage of the throttle handle 103 in response to turning on the cruise control function.

[0042] In some embodiments, the cruise control unit 103 is also used to output a voltage to the ECU 101 when it is monitored that the voltage output by the throttle handle 103 is greater than the target voltage required for the target speed value executed by the cruise control unit 103; or when it is monitored that the voltage output by the throttle handle 103 is less than or equal to the target voltage, output the target voltage to the ECU 101, so as to dynamically adjust the output voltage to maintain the target vehicle speed.

[0043] In the embodiment of the present application, a connection is established between the cruise control unit, the throttle handle voltage and the OBD interface, and the throttle output is adjusted in real time to realize the cruise control function. Compared with the prior art, no additional sensors are required, which avoids major changes to the motorcycle structure and electrical system. It is easy to install, simple to operate, and has low maintenance costs.

[0044] Figure 2 A cruise control logic diagram based on a cruise control system provided in an embodiment of the present application is exemplarily shown.

[0045] After the cruise control function is turned on, the original vehicle button 104 can report the operating data of the motorcycle to the OBD interface 102, and the OBD interface 102 can send the operating data to the cruise control unit 100, and the throttle handle 103 can also send the corresponding voltage to the cruise control unit 100. The cruise control unit can output a speed regulation signal for changing the target cruise control value and a regulating voltage for maintaining the vehicle speed after the target cruise control value based on the operating data and the voltage to the ECU 101, thereby realizing the entire cruise control process.

[0046] Figure 3 The following is an exemplary diagram showing a comparison between the original vehicle system architecture diagram and the cruise control system architecture diagram of the embodiment of the present application. Figure 3 As shown, Figure 3 In (a), the ECU is connected to the OBD interface, throttle handle, and speed control button respectively, and the operation of other components is controlled by the ECU; Figure 3 (b) Figure 3 (a) is based on the invention, and a cruise control unit is added, which is respectively connected with the ECU, the throttle handle and the OBD interface, and other connection relationships remain unchanged, so as to form a cruise control system for a motorcycle to realize the cruise control function. Compared with the prior art, no additional sensors are required, and major changes to the motorcycle structure and electrical system are avoided. In addition, the cruise control unit is easy to install, simple to operate and has low maintenance cost.
