Description

Technical Field

[0001] The present invention relates to the technical field of motorcycles, and in particular to a control method, device and electronic equipment for hybrid power generation of motorcycles. Background Art

[0002] In today's society, motorcycles are a favorite short-distance transportation tool due to their agility and speed. However, with the recent rise of energy shortages and environmental awareness, achieving energy conservation and reducing pollution have become key goals in vehicle development. Hybrid vehicles offer the advantages of reduced fuel consumption and reduced pollution caused by harmful emissions. Consequently, market demand for hybrid vehicles is steadily expanding.

[0003] The main function of power generation control in hybrid motorcycles is to recharge the battery through engine drive or braking energy recovery. Traditional control methods often cause overcurrent or overcharging, which shortens the battery life. Summary of the Invention

[0004] The present application solves the problem of overcurrent or overcharging affecting battery life in the prior art by providing a control method, device and electronic equipment for hybrid power generation of a motorcycle, thereby ensuring that the battery operates within a normal range and extending the battery life.

[0005] In a first aspect, an embodiment of the present invention provides a method for controlling hybrid power generation of a motorcycle, comprising the following steps:

[0006] S1: Real-time collection of battery SOC value, battery voltage, engine speed, brake signal and motor power output;

[0007] S2: obtaining a motor limit torque based on the current battery SOC value, the brake signal, and the current motor power output; obtaining a battery charging allowable torque based on the current battery SOC value and the current battery voltage; obtaining a motor speed torque based on the engine speed; and taking the minimum of the motor limit torque, the battery charging allowable torque, and the motor speed torque as the target torque;

[0008] S3: Control the motor to output the target torque to charge the battery.

[0009] The beneficial effects of the above embodiment are: the control method collects the current information of the whole vehicle in real time, and calculates the motor limit torque, battery charging allowable torque, motor speed torque through the current information, and takes the minimum value of the motor limit torque, battery charging allowable torque, and motor speed torque as the target torque, controls the motor to output at the target torque, recovers electricity, thereby ensuring that the motor charging will not have overcurrent or overcharging, ensuring that the battery operates within the normal range, and extending the battery life.

[0010] According to a specific implementation of an embodiment of the present invention, in step S2, the motor limit torque is obtained as follows: if the battery SOC value is greater than A, the motor limit torque is 0; if the battery SOC value is greater than B and the brake signal is invalid, the motor limit torque is 0; if the battery SOC value is greater than B and the brake signal is valid, or the battery SOC value is ≤B, the motor power generation output power is compared with the set power Y; if the motor power generation output power is ≤Y, the motor limit torque is D; if the motor power generation output power is greater than Y, the time counting is entered; when the counting time is not greater than T, the motor limit torque is D; when the counting time is greater than T, the motor limit torque is F, wherein A, B, D, F, and T are all set values, and A>B, D>F. When the battery SOC value is greater than A, recycling is prohibited to prevent overcharging. When the battery SOC value is greater than B and the brake signal is invalid A, recycling is prohibited, and spare power is reserved for braking recycling to save energy. When the battery SOC value is greater than B and the brake signal is valid, or the battery SOC value is ≤B, according to the current motor power output power, while ensuring charging efficiency, the battery is prevented from being in a high-power fast charging state for a long time, thereby extending the battery life.

This prevents battery overcurrent and extends battery life.

[0013] According to a specific implementation of an embodiment of the present invention, in step S2, the motor speed torque is obtained as follows: a power generation torque array corresponding to the engine speed is pre-determined according to engine characteristics, and the motor speed torque corresponding to the current engine speed is obtained by comparing the current engine speed with the power generation torque array.
