[0002] There are not many horsepower machine manufacturers on the market, especially in China. There are very few manufacturers abroad. There are Italian brands DIMSport and British brand DynaPro. The horsepower machine reflects the speed, power, horsepower and torque values ​​of the motorcycle in real use. In the process of roller simulating the road surface, it is necessary to consider the various forces of the motorcycle driving on the road surface, including the friction between the wheels and the road surface, wind resistance, etc. The influence of various forces on the calculated horsepower of the motorcycle must be taken into account to truly reflect the performance of the motorcycle in real use.

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] like Figure 1 As shown, Figure 11 is a flow chart of a motorcycle performance testing method provided by an embodiment of the present invention. The motorcycle performance testing method comprises the following steps:

[0036] 101. Obtain the current speed of the motorcycle in the road simulation device in real time.

[0037] In an embodiment of the present invention, the above-mentioned motorcycle performance testing method is applied to a motorcycle performance testing system, and the motorcycle performance testing system includes a road simulation device, a wind resistance simulation device, a power absorption device, and a control device, wherein the road simulation device, the wind resistance simulation device, and the power absorption device are respectively connected to the control device, and the above-mentioned control device is used to execute the motorcycle performance testing method.

[0039] Furthermore, the current speed of the motorcycle in the road simulation device can be collected in real time through a high-pulse sensor. The use of a high-pulse photoelectric encoder can ensure the accuracy of speed collection, thereby achieving the purpose of truly reflecting the driving conditions of the motorcycle. Only when the speed is collected accurately can the force exerted on the motorcycle during driving be converted, thereby truly reflecting the performance of the motorcycle in actual use.

[0040] 102. Determine the current wind speed of the motorcycle based on the current speed of the motorcycle.

[0041] In the embodiment of the present invention, the vehicle speed is approximately equal to the wind speed.

[0042] According to the current real-time speed of the motorcycle, the current wind speed of the motorcycle can be calculated based on physical laws or empirical formulas.

[0043] 103. Based on the current wind speed, the wind resistance simulation device is driven to simulate the actual wind resistance environment encountered by the motorcycle when driving on the road.

[0044] In an embodiment of the present invention, the above-mentioned driving wind resistance simulation device includes a fan, which can generate different airflow resistances. The driving wind resistance simulation device is used to simulate the air resistance encountered by a motorcycle when driving on a road.

[0045] Furthermore, the voltage required by the thyristor can be obtained through the current wind speed, so that the fan can blow out a wind speed at the same speed as the vehicle.

[0046] It should be noted that when a motorcycle is driving on the road, it will interact with the air. Air resistance is caused by wind resistance, and its size is related to factors such as the speed, shape and road conditions of the motorcycle. By adding a wind resistance simulation device to the motorcycle performance test system, the air resistance encountered by the motorcycle on the road at different speeds can be simulated. By adjusting the speed of the fan and the amount of air blown out, the air resistance at different speeds can be simulated.

[0047] 104. Based on the real wind resistance environment, the performance of the motorcycle is tested to obtain the performance test results of the motorcycle.

[0048] In the embodiment of the present invention, the above performance test is a performance evaluation process for evaluating the motorcycle at different speeds, wind speeds, etc. The performance test includes tests of acceleration performance, braking performance, handling stability, and other aspects.

[0049] In one embodiment, different wind speeds and angles are simulated to simulate wind resistance during actual driving, and then the speed, acceleration and other parameters of the motorcycle under different conditions are measured to evaluate its performance, which can provide more accurate data and information.

[0050] In an embodiment of the present invention, the present application adds a wind resistance simulation device to the motorcycle performance test system, uses a high-pulse sensor to collect different speeds of the motorcycle in real time, and feeds the speed back to the control module. The control module calculates the voltage required for the thyristor to output the current wind speed, drives the thyristor, and makes the wind resistance simulation device blow out the same wind speed as the vehicle speed, thereby simulating the actual wind resistance encountered by the motorcycle when driving on the road, making the test more realistic and more convincing.

[0051] In an embodiment of the present invention, the current speed of the motorcycle in the road simulation device is obtained in real time; the current wind speed of the motorcycle is determined according to the current speed of the motorcycle; based on the current wind speed, the wind resistance simulation device is driven to simulate the real wind resistance environment encountered by the motorcycle when driving on the road; based on the real wind resistance environment, the motorcycle is subjected to a performance test to obtain the performance test result of the motorcycle. The present invention determines the current wind speed of the motorcycle according to the current speed of the motorcycle, and drives the wind resistance simulation device to simulate the real wind resistance environment encountered by the motorcycle when driving on the road according to the current wind speed, and uses the real wind resistance environment to perform a performance test on the motorcycle to obtain the performance test result of the motorcycle, thereby solving the problem that the existing method has the problem that the motorcycle is not subjected to wind resistance, and even if a reaction force is added to the drum, there will be deviations from the real wind force, which is different from the actual use, resulting in the inability to truly reflect the real performance of the motorcycle when driving on the road.

[0052] It should be noted that the motorcycle performance testing method provided in the embodiment of the present invention can be applied to motorcycle performance testing systems, smart phones, tablets, computers, servers and other devices that can perform the motorcycle performance testing method.

[0053] It is understandable that in the specific implementation of this application, user data, item data, order data and other related data are involved. When the embodiments in this application are applied to specific products or technologies, user permission or consent is required, and the collection, use and processing of relevant data, as well as model training, deployment and use, must comply with relevant laws, regulations and standards of relevant countries and regions.

[0054] like Figure 2 As shown, Figure 2 1 is a flow chart of another motorcycle performance testing method provided by an embodiment of the present invention. The motorcycle performance testing method comprises the following steps:

[0055] 200. Start.

[0056] 201. Motorcycle performance test.

[0057] The motorcycle is subjected to performance testing in the motorcycle performance testing system. The motorcycle performance testing system comprises a road simulation device, a wind resistance simulation device, a power absorption device, and a control device, wherein the road simulation device, the wind resistance simulation device, and the power absorption device are respectively connected to the control device.

[0058] The road simulation device is composed of a stand and a roller, which are used to simulate the ground resistance encountered by a motorcycle on the road; the wind resistance simulation device includes a fan, which is used to simulate the air resistance encountered by a motorcycle when driving on the road; the power absorption device is used to collect the power of the motorcycle when it is driving on the motorcycle performance test system; the control device uses an industrial computer and a single-chip microcomputer to control and process the motorcycle, and uses a high-precision rotary photoelectric encoder and a force sensor to collect the speed, ambient temperature, etc. of the motorcycle. By collecting the speed and wind speed data and calculating the voltage required by the thyristor, the fan can blow out the wind speed at the same speed, thereby controlling the entire motorcycle performance test system to simulate the wind force and friction encountered during road driving, thereby realizing real performance testing.

[0059] 202. Monitor speed in real time.

[0060] Among them, during the performance test, the speed of the motorcycle is collected in real time by using a high-pulse sensor, which can ensure the accuracy of speed collection, thereby achieving the purpose of truly reflecting the driving conditions of the motorcycle. Only when the speed is collected accurately can the force exerted on the motorcycle during driving be calculated, thereby truly reflecting the performance of the motorcycle in actual use.

[0061] 203. The corresponding voltage of thyristor output.

[0062] The wind speed is determined according to the vehicle speed, and the voltage required by the thyristor at each wind speed point is determined.

[0063] 204. Fan output corresponds to wind speed.

[0064] The voltage required by the thyristor is obtained through the wind speed, so that the fan can blow out a wind speed at the same speed as the vehicle.

[0065] 205. End.

[0066] In an embodiment of the present invention, the present invention uses a high-pulse sensor to collect different speeds of the motorcycle in real time, and feeds the speed back to the control module. The control module calculates the voltage required for the thyristor to output the current wind speed, outputs the required PWM value, and drives the thyristor, thereby controlling the fan to blow out a wind speed the same as the vehicle speed, thereby simulating the actual wind resistance encountered by the motorcycle when driving on the road and realizing real performance testing.

[0067] Optionally, the motorcycle performance testing system also includes a thyristor. In the step of driving the wind resistance simulation device to simulate the actual wind resistance environment encountered by the motorcycle when driving on the road based on the current wind speed, the target voltage required for the thyristor to output the current wind speed can be determined based on the current wind speed; the thyristor is driven by the target voltage to control the wind resistance simulation device to simulate the actual wind resistance environment encountered by the motorcycle when driving on the road.

[0068] In the embodiment of the present invention, the thyristor has the advantages of small size, high efficiency, long life, etc. In the dynamic control system, it can be used as a high-power driving device to control high-power equipment with a low-power control device.

[0069] Specifically, the target voltage required for the thyristor to output the current wind speed can be obtained through the current wind speed and the corresponding relationship between the voltage and the wind speed.

[0070] The above correspondence between voltage and wind speed can be understood as the correspondence between the voltage required by the thyristor at different wind speeds.

[0071] The wind resistance simulation device is used to simulate the air resistance encountered by a motorcycle when it is traveling on the road.

[0072] It should be noted that the target voltage required for the thyristor to output the current wind speed can be determined based on the current wind speed and the corresponding relationship between voltage and wind speed, and the thyristor can be controlled based on the target voltage so that the wind resistance simulation device can simulate the actual wind resistance environment encountered by a motorcycle when driving on the road, thereby realizing the simulation of the actual wind resistance environment by the wind resistance simulation device.

[0073] Optionally, the wind resistance simulation device includes a fan. In the step of driving the thyristor by the target voltage to control the wind resistance simulation device to simulate the actual wind resistance environment encountered by the motorcycle when driving on the road, the thyristor can be driven by the target voltage to control the fan to blow out wind corresponding to the current wind speed, so that the wind resistance simulation device simulates the actual wind resistance environment encountered by the motorcycle when driving on the road.

[0074] In an embodiment of the present invention, the wind resistance simulation device is used to simulate the air resistance encountered by a motorcycle when it is traveling on a road. The fan can generate different air flow resistances.

[0075] Specifically, when a motorcycle is driving on the road, it will interact with the air. Air resistance is caused by wind resistance, and its magnitude is related to factors such as the speed, shape and road conditions of the motorcycle. By adding a wind resistance simulation device to the motorcycle performance test system, the air resistance encountered by the motorcycle on the road at different speeds can be simulated. By adjusting the speed of the fan and the amount of air blown out, the air resistance at different speeds can be simulated.

[0076] The above target voltage is the output voltage required by the thyristor at the current wind speed.

[0077] Optionally, before determining the target voltage required for the thyristor to output the current wind speed based on the current wind speed, the historical test vehicle speed can be obtained; based on the historical test vehicle speed, the voltage required for the thyristor at each wind speed point corresponding to the vehicle speed can be determined.

[0078] In the embodiment of the present invention, the above historical test vehicle speed is the driving speed of the vehicle under different working conditions in the past period of time.

[0079] Furthermore, by testing the historical test speed, the voltage required by the thyristor at each wind speed point is determined, and the wind speed point can be accurately determined to 1km / h. Because motorcycles accelerate quickly, the wind speed point accuracy is sufficient to provide the actual resistance encountered by the motorcycle during use.

[0080] Optionally, in the step of determining the voltage required by the thyristor for each wind speed point corresponding to the vehicle speed based on the historical test vehicle speed, the distribution of each wind speed point corresponding to the vehicle speed can be determined based on the historical test vehicle speed, with a preset vehicle speed difference between two adjacent wind speed points; and based on the corresponding relationship between voltage and wind speed, the voltage required by the thyristor for each wind speed point can be determined.

[0081] In the embodiment of the present invention, the above wind speed points can be understood as speed values ​​of the vehicle at different speeds.

[0082] The above-mentioned preset vehicle speed difference is a vehicle speed difference preset by the system, which is used to indicate the speed variation range of the vehicle within these two speed intervals.

[0083] The above correspondence between voltage and wind speed is obtained in advance through experiments or theoretical analysis. The correspondence between voltage and wind speed can be understood as the voltage required by thyristors at different wind speeds. A corresponding voltage required by thyristors is assigned to each wind speed point. This voltage represents the voltage that the thyristor needs to reach at a given wind speed.

[0084] It should be noted that the distribution of wind speed points at different vehicle speeds can be determined based on historical test vehicle speeds, and then the voltage required by the thyristor at each wind speed point can be calculated based on the corresponding relationship between voltage and wind speed.

[0085] Optionally, in the step of determining the target voltage required for the thyristor to output the current wind speed based on the current wind speed, the target voltage required for the thyristor when the wind turbine outputs the current wind speed may be determined based on the corresponding relationship between voltage and wind speed.

[0086] In the embodiment of the present invention, the correspondence between the voltage and the wind speed includes different voltage values ​​required by the thyristor at different wind speeds.

[0087] Specifically, according to the current wind speed and in combination with the corresponding relationship between voltage and wind speed, the target voltage required by the thyristor when the wind turbine outputs the current wind speed is determined.

[0088] The above target voltage is the output voltage required by the thyristor at the current wind speed.

[0089] like Figure 3 As shown, an embodiment of the present invention provides a motorcycle performance testing system, which includes: a road simulation device, a wind resistance simulation device, a power absorption device, and a control device, wherein the road simulation device, the wind resistance simulation device, and the power absorption device are respectively connected to the control device, and the control device is used to execute the motorcycle performance testing method provided by the embodiment of the present invention.

[0090] In the real-time example of the present invention, the motorcycle performance test system can be a motorcycle test horsepower machine, which can simulate various resistances encountered by a motorcycle when it is traveling on the road, including ground resistance, wind resistance, etc.

[0091] The above-mentioned road simulation device is a device used to simulate the road conditions of vehicle driving, and can simulate the ground resistance, side friction, etc. encountered by the vehicle when driving.

[0092] Optionally, the road simulation device is composed of a test bench and a roller, which is used to simulate the ground resistance encountered by a motorcycle on the road; the wind resistance simulation device includes a fan, which is used to simulate the air resistance encountered by a motorcycle when traveling on the road; the power absorption device is used to collect the power of the motorcycle when traveling on the motorcycle performance test system.

[0093] In the embodiment of the present invention, the above-mentioned test bench is a frame structure that can support the weight of the vehicle, can provide stable support and ensure the safety of the test; the above-mentioned roller can simulate the friction and rolling resistance under different road conditions.

[0094] The above-mentioned fans can generate different air flow resistances. Specifically, when a motorcycle is driving on the road, it will interact with the air. Air resistance is generated by wind resistance, and its magnitude is related to factors such as the speed, shape and road conditions of the motorcycle. By adding a wind resistance simulation device to the motorcycle performance test system, the air resistance encountered by the motorcycle on the road at different speeds can be simulated. By adjusting the speed of the fan and the amount of air blown out, the air resistance conditions at different speeds can be simulated.

[0095] The power absorption device can be an air-cooled eddy current dynamometer. The air-cooled eddy current dynamometer is a device that uses the eddy current principle to measure torque and power. A changing magnetic field is generated on the rotor, thereby generating a current in the stator corresponding to the change in the magnetic field. This current changes with the rotation of the rotor, thereby reflecting the input power.

[0096] Furthermore, during the performance test, the motorcycle wheel is supported on the drum and driven to rotate the drum. The rotor of the eddy current dynamometer (equivalent to an electromagnetic disk) is connected to the main drum of the test bench and rotates in the middle of the stator (surrounded by an excitation coil). When the excitation coil passes direct current, a magnetic field is generated between the two poles, and the rotor rotates through the magnetic field of the excitation coil, thereby generating eddy currents on the rotor disk. Due to the interaction between the eddy current and the external magnetic field, a braking resistance torque is generated on the rotor disk. This resistance torque is transmitted to the force sensor through the connecting rod connected to the housing of the eddy current dynamometer. The sensor converts it into an electrical signal and sends it to the computer for processing. As long as the current in the excitation coil is adjusted, the range of the braking resistance torque (i.e., the absorbed power) can be changed. When the driving torque and the above resistance torque are balanced, the driving force can be obtained. Multiplying it by the speed of the drum at this time (obtained in real time by the high pulse sensor) will obtain the output power of the driving wheel at this speed.

[0097] Furthermore, the power consumption of the motorcycle under road driving conditions can be collected in real time through an air-cooled eddy current dynamometer.

[0098] Optionally, the motorcycle performance test system further includes a thyristor, and the control device includes a single-chip microcomputer;

[0099] The control device obtains the current speed of the motorcycle in the road simulation device in real time, and feeds the current speed back to the single-chip microcomputer. The single-chip microcomputer calculates the voltage required by the thyristor to output the current wind speed, and drives the wind resistance simulation device to simulate the actual wind resistance environment encountered by the motorcycle when driving on the road.

[0100] In the embodiment of the present invention, the above-mentioned thyristor is the abbreviation of thyristor rectifier element, which is a high-power semiconductor device with a four-layer structure and three PN junctions. The thyristor has the advantages of small size, high efficiency, long life, etc. In the dynamic control system, it can be used as a high-power driving device to realize the control of high-power equipment with a small-power control component.

[0101] The above-mentioned single chip microcomputer is a computing device integrating a processor, memory and input / output interface.

[0102] The above control device can use industrial computers and single-chip microcomputers for control processing, which can ensure the reliability and real-time performance of the system.

[0103] In this embodiment, data acquisition and processing are performed through a single-chip microcomputer, and a high-precision rotary photoelectric encoder and a force sensor are used to collect different speeds of the motorcycle in real time, and the speed is fed back to the single-chip microcomputer. The single-chip microcomputer calculates the voltage required for the thyristor to output the current wind speed, outputs the required PWM value, and drives the thyristor, thereby controlling the fan to blow out the same wind speed as the vehicle speed, thereby simulating the actual wind resistance of the motorcycle when driving on the road and realizing the real performance test. The single-chip microcomputer is used for data acquisition and processing, and a high-precision rotary photoelectric encoder and a force sensor are used to collect the speed of the motorcycle, the ambient temperature, etc., which has strong anti-interference ability, can ensure that the error of the collected speed and the output force is small, the situation is real, and it is easier to reflect the real performance of the motorcycle.

[0104] It should be noted that the motorcycle performance test system provided by the embodiment of the present invention can be applied to motorcycle performance test systems, smart phones, tablets, computers, servers and other devices that can perform motorcycle performance test methods.

[0105] The motorcycle performance test system provided by the embodiment of the present invention can implement each process implemented by the motorcycle performance test method in the above method embodiment and can achieve the same beneficial effects.
