Abstract

Abstract

Low-power brushless DC motor (BLDC) in vehicles is prone to failures under complex operating conditions and harsh environments, while traditional detection measures relying on a single threshold setting often lead to issues such as false alarms, missed detections, and over-protection. A fault protection measure for vehicle motors was proposed, which was monitored by setting multi-threshold and sensitive value at the software level, and optimized circuit design at the hardware level. By monitoring the key voltage and current parameters of the test vehicle motor, combined with real-time data, experience and model simulation, multiple thresholds and sensitive values were set to judge the running state of the vehicle motor. According to the triggering conditions of different thresholds, corresponding protection measures were taken, and fault protection test bench was set up to analyze the signals received by the upper computer. The results show that the measure is feasible and correct.
