Abstract

The present invention provides a vehicle speed control system for an electric vehicle, which includes a motor controller and a vehicle controller, wherein the vehicle controller includes a second communication unit and an instruction collection unit, and the motor controller includes a first communication unit and a power drive unit; The command collection unit is used to collect cruise control commands and set vehicle speeds; the second communication unit sends the constant speed cruise commands and set vehicle speeds to the first communication unit; the power drive unit is used to A communication unit receives the constant speed cruise command and sets the vehicle speed to enter the speed mode; in the speed mode, the power drive unit adjusts its output frequency to the frequency corresponding to the set speed, and adjusts the output torque to make it The output torque matches the load torque. The invention also provides a corresponding method. The invention realizes the constant-speed operation of the electric vehicle by adjusting the output frequency corresponding to the set vehicle speed, and improves the driving stability, safety and comfort of the electric vehicle.

Description

technical field [0001] The invention relates to the field of electric vehicle control, and more specifically relates to a vehicle speed control system and method for an electric vehicle. Background technique [0002] With the development of the economy, the automobile has become one of the indispensable tools in human life, and the automobile industry has become one of the pillar industries of the modern economy. With the continuous growth of global automobile production and ownership, the use of internal combustion engines as driving power has brought serious environmental pollution and increasingly urgent global oil resource crises, which has also led to countries around the world having to seek low-emission, A new type of transportation using new energy. Electric vehicles have the characteristics of low pollution, low noise, energy saving, simple structure, control and maintenance, etc., and are an effective way to solve environmental and energy problems. [0003] The a...
