In addition, when the environment parameter is uphill in geography, to ensure safe travel, the power output of the motorcycle can be increased.
An embodiment of the present disclosure provides a method for controlling a motorcycle, which can flexibly control the power output, such as motor power output, on the motorcycle by using the obtained environment parameter of the motorcycle and the assist parameter of the motorcycle during operation. When the motorcycle is in a certain external environment, the limitation of controlling the motor by using only the assisting parameter is solved, and the safety of the user's travel is improved.
In an embodiment according to the present disclosure, reducing the power output of the motorcycle according to the environment parameter and the assisting parameter may include at least one of the following situations, which can achieve flexible control of the motorcycle according to the environmental parameter and the assisting parameter under different environment parameter. The purpose of safe travel is achieved.
1) If the direction of the local wind speed as the environment parameter is the same as that of the motorcycle, the power output of the motorcycle can be reduced according to the first preset rule and the torque parameter as the assist parameter.
In an embodiment according to the present disclosure, the first preset rule refers to how to adjust the output power of the power on the motorcycle according to the wind speed and torque parameter. That is, the first preset rule may be to determine the power output of the motorcycle according to the wind speed and the torque parameter. For example, if the torque parameter is the user's pedaling force torque collected by the torque sensor, and the power output is the motor output power on the motorcycle, the first preset rule may be a preset comparison table. such as when the wind speed is greater than level 3 and less than or equal to level 4, the output power of the motor is reduced by 20%. That is, the output power of the motor can be reduced by 20% based on the value calculated based on the user's pedaling torque. When the wind speed is greater than level 5, the output of the motor is reduced by 50%. That is, the output power of the motor can be reduced by 50% based on the value calculated based on the user's pedaling force torque, etc.
The data of the torque parameter, the magnitude of the wind speed, and the output power of the motor provided by the embodiments of the present disclosure are merely examples, and the embodiments of the present disclosure do not limit the content of the torque parameter, the wind speed, and the output power of the motor in the first preset rule.
(2) When the motorcycle is under the condition of rain or snow, the power output of the motorcycle is reduced according to the second preset rule and the torque parameter as a boost parameter based on the rainfall or snowfall in the environment parameter.
In an embodiment of the present disclosure, the second preset rule refers to how to adjust the output power of the motor on the motorcycle according to the rainfall or snowfall amount and the torque parameter. That is, the second preset rule may be based on the rainfall amount, snowfall amount, and the torque parameter to determine the power output of the motorcycle. In an embodiment, the power output is the output power of the motor on the motorcycle. The rainfall amount may be divided into light rain, moderate rain, heavy rain, etc. The second preset rule may be a preset comparison table. For example, when the rainfall is less than 5 mm, the output power of the motor may remain unchanged. That is, the output power of the motor may be calculated based on the torque parameter. When the rainfall is greater than 5 mm and less than 15 mm, the output power of the motor may be reduced by 10%. That is, the output power may be reduced by 10% based on the value calculated based on the torque parameter. When the rainfall is greater than 15 mm and less than 25 mm, the output power of the motor may be reduced by 20%. That is, the output power of the motor may be reduced by 20% based on the value calculated based on the torque parameter.

That is, the output of the motor may be a value calculated based on the torque parameter, or it may be reduced by 10% based on the value calculated based on the torque parameter. When the snowfall is greater than 1 mm and less than 3 mm (medium snow), the output power of the motor may be reduced by 20%. That is, the output power of the motor may be reduced by 20% based on the value calculated based on the torque parameter. When the snowfall is greater than 5 mm (heavy snow), the output power of the motor may be reduced by 50%. That is, the output power of the motor may be reduced by 50% based on the value calculated based on the torque parameter.
The data of the amount of rainfall (or snowfall), the torque parameter, and the output power of the motor provided by the embodiments of the present disclosure are merely examples. The embodiments of the present disclosure are not limited to the torque parameter, rainfall, or snowfall in the second preset rule when the motor output power is limited.

In an embodiment of the present disclosure, the haze concentration may be represented by PM2.5 (Particulate Matter, PM). For example, the haze may be divided into three levels: medium haze, severe haze, and much severe haze. In one embodiment, the power output is the output power of the motor on the motorcycle. The third preset rule may be used to adjust the output power of the motor on the motorcycle according to the haze concentration and torque parameter. That is, the power output of a motorcycle may be determined based on the haze concentration and torque parameter according to the third preset rule. For example, when the haze concentration is greater than 115 ug/m3 and less than 150 ug/m3 (moderate haze), the output power of the motor may be reduced by 10%. That is, the output power of the motor may be reduced 10% based on the value calculated based on the torque parameter.

When the haze concentration is greater than 250 ug/m3 (very severe haze), the output power of the motor may be reduced by 50% to 80%. That is, the output power of the motor may be reduced by 50% to 80% based on the value calculated based on the torque parameter.
The torque parameter, the amount of haze concentration, and the output power of the motor provided by the embodiments of the present disclosure are just an example, and the embodiment is not limited the content of the torque parameter, the haze concentration, and the output power of the motor in the third preset rule.

In an embodiment, the power output power may be the output power of the motor on the motorcycle, and the fourth preset rule may refer to how to adjust the output power of the motor on the motorcycle according to a preset time period and torque parameter. That is, the fourth preset rule may be used to determine the power output according to the season, the preset time period, and the torque parameter. The fourth preset rule may also be a preset comparison table. For example, in summer, when a user rides a motorcycle between 8 PM and 10 PM, the output power of the motor may be reduced by 20%. That is, the output power of the motor may be reduced by 20% based on the value calculated based on the torque parameter. The specific reduction ratio may be determined according to actual conditions, and is not limited to the examples provided herein.

Exemplarily, the power output power may be the output power of the motor on the motorcycle, and the fifth preset rule may refer to how to adjust the output power of the motor on the motorcycle according to the concentration and torque parameter of the sand storm. That is, the power output is determined according to the dust storm concentration and torque parameter and the fifth preset rule. In one embodiment, the concentration of the sandstorm may correspond to the visibility, and the greater the concentration, the lower the visibility. For example, when the visibility is greater than 500m and less than 1000m (weak sandstorm), the output power of the motor may be reduced by 10%. That is, the output power of the motor may be reduced by 10% based on the value calculated based on the torque parameter. When the visibility is greater than 200m and less than 500m (medium intensity dust storm), the output power of the motor may be reduced by 20%. That is, the output power of the motor may be reduced by 20% based on the value calculated based on the torque parameter. When the visibility is less than 200m (strong sand storm), the output power of the motor may be reduced by 50% to 80%. That is, the output power of the motor may be reduced by 50% to 80% based on the value calculated based on the torque parameter, and so on.

That is, the sixth preset rule may determine the power output according to the steepness of the downhill slope and the torque parameter. In an embodiment, the sixth preset rule may be a preset comparison table. For example, when the slope is less than 10, the output power of the motor will be reduced by 10%. That is, the output power of the motor may be reduced by 10% based on the value calculated based on the torque parameter. When the slope is greater than 10 and less than 30, the output power of the motor may be reduced by 20%. That is, the output power of the motor may be reduced by 20% based on the value calculated based on the torque parameter. When the slope is greater than 30 and less than 60, the output power of the motor may be reduced by 50%. That is, the output power of the motor can be reduced by 50% based on the value calculated based on the torque parameter. When the slope is greater than 60, the output power of the motor may be reduced by 80%. That is, the output power of the motor may be reduced by 80% based on the value calculated based on the torque parameter, and so on.

That is, the seventh preset rule may determine the power output according to the steepness of the uphill and the torque parameter. For example, when the slope is less than 10, the output power of the motor may increase by 10%. That is, the output power of the motor may be reduced by 10% based on the value calculated based on the torque parameter. When the slope is greater than 10 and less than 30, the output power of the motor may increase by 20%. That is, the output power of the motor may be reduced by 20% based on the value calculated based on the torque parameter. When the slope is greater than 30 and less than 60, the output of the motor may increase by 50%. That is, the output power of the motor may be reduced by 50% on the basis of the value calculated based on the torque parameter. When the slope is greater than 60, the output of the motor may increase by 80%. That is, the output power of the motor may be reduced by 80% on the basis of the value calculated based on the torque parameter.
