Abstract

The invention discloses a distributed electric drive control system and method based on perpendicular load real-time estimation. A distributed drive controller is connected with an electronic accelerator pedal, a steering wheel angle sensor, an acceleration sensor, a tire pressure sensor, a left front wheel hub motor controller, a right front wheel hub motor controller, a left back wheel hub motor controller and a right back wheel hub motor controller through a CAN communication network. The left front wheel hub motor controller is connected with a left front wheel hub motor. The right front wheel hub motor controller is connected with a right front wheel hub motor. The left back wheel hub motor controller is connected with a left back wheel hub motor. The right back wheel hub motor controller is connected with a right back wheel hub motor. According to the distributed electric drive control system and method based on perpendicular load real-time estimation, the problem that the real-time performance and the accuracy are poor in the traditional vehicle perpendicular load estimation algorithm is broken through, and the handling stability and the driving safety of a distributed drive electric automobile under the actual working conditions are improved.

Description

technical field [0001] The invention belongs to an electric vehicle drive control system, in particular to a distributed drive control system and method for electric vehicles based on real-time estimation of wheel vertical loads. Background technique [0002] Distributed drive electric vehicles using hub / wheel motors are an important development direction of electric vehicles in the future. Because its four-wheel drive torque is independently controllable and the torque speed is easy to measure, it has significant control advantages over traditional vehicles and centralized electric vehicles in terms of stability, active safety control and energy saving. It is a new generation of vehicle control technology. , An ideal carrier for exploring vehicle dynamics. Among them, in the research on the key technology of distributed drive electric vehicle control, there have been many related researches such as driving force distribution control, and an important part of the existing c...
