METHODS AND SYSTEMS FOR DETECTING CURRENT SENSOR ERROR |
摘要 |
Methods and systems are provided for controlling an electric motor in a vehicle. A method comprises measuring current associated with a first phase of the electric motor using a first current sensor resulting in a measured first phase current and measuring current associated with a second phase of the electric motor using a second current sensor resulting in a measured second phase current. The method further comprises determining a target value for the measured second phase current based on a value corresponding to a peak current for the first phase and identifying a current sensor error based on a difference between the measured second phase current and the target value.
