Title: Method of determining the rotor position of a permanent-magnet motor
Inventor: LIBO ZHENG
IPC: H02P6/26
Filed: 2016-04-26
Abstract: A method of determining the position of a rotor of a brushless permanent-magnet motor (PMM) by: exciting and freewheeling a phase winding of the motor, wherein the phase winding is freewheeled when a phase current exceeds an upper threshold; measuring a parameter and using it to define a saturation threshold; sequentially exciting and freewheeling in the same manner and comparing the measured parameter against the saturation threshold; determining that the rotor is at a predetermined position when the measured parameter is less than the saturation threshold. The measured parameter may be the magnitude of the phase current during, or at the end of, freewheeling, wherein the phase winding is freewheeled for a fixed period. Alternatively, the measured parameter may be the time interval between either: the start and end of freewheeling; or the start and end of excitation, wherein the phase winding is freewheeled until the phase current falls below a lower threshold. When the rotor is determined to be at the predetermined position, the phase winding may be commutated after a commutation period has elapsed, wherein the length of the commutation period depends on the speed of the rotor. The saturation threshold may be defined by subtracting a fixed offset value from the measured parameter.

If the condition during ignition is determined as under duress, the decision unit commands ignition of engine and user's preferred settings, and the data commu­nication module to send a notification to an external party simultaneously. The driver may register different biometric identifiers to the system, such as at least two different fingerprints and a facial image under normal conditions. A first fingerprint may be input, and recognised, under normal circumstances, while the input of a second, different, fingerprint may indicate the duress condition to the system.
