The present invention provides an electric vehicle power-assisted running control system and method thereof. The control system includes a pedal sensor module, an expected torque calculation module, a torque output calculation module, an assist ratio setting module, and an actual torque acquisition module; The pedal sensor module provides speed signals and torque information to the expected torque calculation module to calculate the expected torque; the assist ratio setting module is used to control the ratio of the expected torque output, and the torque output calculation module, through The expected torque and actual torque are used to calculate the size of the actual torque that needs to be output; the method of controlling the actual torque output by using the pedal frequency sensor and torque sensor and the assist ratio setting to control the actual torque output solves the problem of insufficient power assist in the operation of electric bicycles in the existing market. Good, poor dynamic performance.
Description
technical field [0001] The invention relates to the technical field of permanent magnet synchronous motors, in particular to an electric vehicle power-assisted operation control system and a control method thereof. Background technique [0002] In recent years, electric bicycles have gradually become an indispensable means of transportation for people to travel due to their green, environmental protection, economy, and convenience. However, the traditional pure electric bicycle makes the output efficiency of the motor extremely low, which not only causes a waste of resources, but also seriously affects the battery life. Along with the raising of people's living standard, therefore, electric power-assisted bicycle enters the sight of the public gradually. It is a "manpower-based, motor-assisted" driving method, that is, driving is driven by mixing pedaling torque and motor output torque. Today, when advocating green travel, electric power-assisted bicycles may be an excelle...
