Title
(EN) METHOD AND APPARATUS FOR STARTER MOTOR DIAGNOSIS AND PROGNOSIS USING PARAMETER ESTIMATION ALGORITHM
(FR) PROCÉDÉ ET APPAREIL POUR LE DIAGNOSTIC ET LE PRONOSTIC DE DÉMARREUR UTILISANT UN ALGORITHME D’ESTIMATION DE PARAMÈTRE
Abstract
(EN)
A system and method for determining the state of health of a starter motor to notify a vehicle driver of a potential starter motor failure before the failure actually occurs. The starter motor includes an armature and motor brushes each providing a resistance, and an armature coil providing an armature inductance. Further, the starter motor has a back EMF because of the starter motor being coupled to a flywheel and the vehicle engine. The system and method monitor the combined resistance of the armature and the motor brushes, the inductance of the armature and a back EMF constant of the motor, and provide a signal indicating a potential starter motor failure if any of these three values significantly deviates from nominal values. In one embodiment, the analysis of the motor resistance, armature inductance and back EMF constant is provided by a regression model to determine estimated motor parameters.

Un système et un procédé de détermination de l’état d’un démarreur permettent d’informer l’automobiliste d’une défaillance de démarreur potentielle avant que la défaillance ne se produise réellement. Le démarreur comprend un induit et des balais de moteur fournissant chacune une résistance, et une bobine d’induit fournissant une inductance d’induit. En outre, le démarreur a une force contre-électromotrice du fait du démarreur couplé à un volant et au moteur de véhicule. Le système et le procédé surveillent la résistance combinée de l’induit et des balais de moteur, l’inductance de l’induit et d’une force contre-électromotrice constante du moteur, et fournissent un signal indiquant une défaillance de démarreur potentielle si l’une de ces trois valeurs s’écarte de manière significative des valeurs nominales. Dans un mode de réalisation, l’analyse de la résistance de moteur, de l’inductance d’induit et de la constante de force contre-électromotrice est fournie par un modèle de régression pour déterminer des paramètres de moteur estimés.
