Abstract

The invention discloses a speed closed-loop control system and method and a vehicle. The system comprises a first control assembly for identifying the current working condition of the vehicle and generating the target speed and target acceleration of the vehicle, and a second control assembly for acquiring the current speed and current acceleration of the electric vehicle, obtaining the target torque according to the current working condition, the target speed, the target acceleration, the current speed and the current acceleration and transmitting the target torque to a motor controller to make a motor of the electric vehicle conduct outputting according to the target torque. The speed closed-loop control system can integrate multiple speed closed-loop systems to achieve hierarchical control of the vehicle, reduce the structural redundancy, reduce the maintenance cost and improve the practicability of the vehicle, and is simple and easy to implement.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a speed closed-loop control system, method and vehicle. Background technique [0002] At present, multiple speed closed-loop application systems such as the creep system and cruise control system of the vehicle are developed as a separate subsystem. Each subsystem calculates the target torque separately and sends it to the MCU (Motor Control Unit, motor control unit) to Control the vehicle as a whole. [0003] However, in related technologies, multiple developers are required to maintain the above-mentioned subsystems of each application, resulting in high maintenance costs, and although there are units with duplicate functions among various application subsystems, they cannot be reused efficiently, wasting resources, While the cost is high, the structure is redundant and needs to be improved. Contents of the invention [0004] The present invention aims to solve one of the ...
