Title:
CRUISING RANGE ESTIMATION METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2024/082201
Kind Code:
A1
Abstract:
A cruising range estimation method and apparatus. The method comprises: acquiring a first running path, remaining energy and real-time driving behavior data of a vehicle; then performing driving style identification on the real-time driving behavior data to obtain a real-time driving style, and predicting a vehicle operation working condition of the vehicle according to the first running path and the real-time driving style; controlling a vehicle mirroring model to run under the vehicle operation working condition, so as to determine predicted energy consumption, wherein the vehicle mirroring model is constructed according to a digital twin algorithm; determining target energy consumption according to the predicted energy consumption and historical average energy consumption; and estimating a cruising range of the vehicle according to the remaining energy and the target energy consumption. The predicted energy consumption obtained by means of digital twin technology and the historical average energy consumption obtained by means of historical data of the vehicle are taken into account to determine the target energy consumption, and the cruising range can be estimated more accurately according to the target energy consumption.
