Document Type and Number:
WIPO Patent Application WO/2024/012293
Kind Code:
A1
Abstract:
A method for diagnosing the failure of an electric driving component of a vehicle, and a control apparatus and a vehicle, which method, apparatus and vehicle aim to solve the existing problems of an electric driving component monitoring device, which is composed of a vibration sensor, an additional circuit, etc., needing to be introduced into state monitoring of an electric driving component of a vehicle, resulting in a relatively high cost, and the accuracy of a monitoring result decreasing along with the increase in the usage duration. The method for diagnosing the failure of an electric driving component of a vehicle can be implemented only by means of software, and comprises the following steps: determining whether the current traveling vehicle meets a condition of entering a diagnosis mode (S11); and if the condition of entering the diagnosis mode is met, inputting collected working condition data and sensor data of the vehicle into a thermal network model, so as to obtain a failure diagnosis result of an electric driving component (S12). The implementation cost is low, deployment and application are facilitated, and the diagnosis precision can be further improved according to the current traveling vehicle meeting a condition of entering a diagnosis mode.
