<p>PROBLEM TO BE SOLVED: To provide a driving force distribution device in which vehicle travelling stability has been improved when switching from 4WD to 2WD, even when a temperature sensor becomes ground fault abnormality.SOLUTION: When temperature sensor ground fault abnormality determination means determines a temperature sensor to be ground fault abnormality, instead of immediately cutting-off control of a driving force distribution device, control by the temperature sensor is switched to control by temperature estimation means. As a result, control of an operation of torque coupling can be continued by the temperature detected by the temperature estimation means, so that the driving force distribution device can be provided in which vehicle travelling stability has been improved.</p> |
