Title:
DATA-DRIVEN METHOD AND APPARATUS FOR IDENTIFYING ADHESION STABILITY OF ELECTRIC-DRIVEN VEHICLE
Document Type and Number:
WIPO Patent Application WO/2021/115063
Kind Code:
A1
Abstract:
An identification method and apparatus for estimating adhesion stability of an electric-driven vehicle on the basis of directly measured parameters such as driving force, acceleration, and identified road type. The motor driving torque is measured by a motor driving torque acquisition unit, the acceleration of a vehicle along the longitudinal axis of the vehicle body is measured by an acceleration acquisition unit, a road type parameter is identified by a road type parameter acquisition unit, the three types of signals are input to a trained identification device to obtain an adhesion stability parameter of the vehicle, and the stability state of the vehicle is determined according to the obtained adhesion stability state. There is no need to estimate or calculate a signal that is difficult to accurately estimate or measure, and the invention has the advantages of being simple and reliable, quick response, and good practicability.
