Title:
POWER TRANSMISSION CONTROL DEVICE OF CAR
Document Type and Number:
Japanese Patent JP3112992
Kind Code:
B2
Abstract:

PURPOSE: To reduce the power consumption by furnishing a means to shut the current feed to a differential motion restricting mechanism regardless of which differential motion restriction amount is selected by a scanning means at the time the car is stopped.
CONSTITUTION: A differential motion restriction amount controller 20 is installed for outputting a control current to a differential mechanism of electromagnetic clutch type (EMCD). This controller 20 is fed with information from a throttle sensor 21, brake sensor 22, neutral sensor 23, and wheel rotation sensors 25, 26, 27, 28. On the basis of information, the controller 20 emits a control current to the EMCDs furnished on a center differential 3, front differential 7, and rear differential 12, and their differential motion restriction amounts are controlled. When information that the car body speed is zero and the transmission 2 is in neutral position, is fed to the controller 20, the control current values for the three differentials 3, 7, 12 are all nullified, which achieves saving the electric power.
