Title: Torque divider system for four-wheel drive motor vehicle
Inventor: KUSANO MASAHIRO
IPC: B60K28/16
Filed: 1997-03-20
Abstract: The system has a friction clutch (37) to divide the torque generated by an engine (1) between front and rear, or left and right wheels. Sensors monitor the wheel speeds. A control unit (60) reacts to the wheel speeds to calculate a speed differential between rear and front wheels, respectively left and right wheels, and to calculate an instruction signal. This reacts to the speed differential and gives an engagement force for the friction clutch. An actuator unit (50) is connected to the clutch to actuate it in response to the instruction signal. The control unit contains a processor, which determines a wheel speed differential based on individual speed differentials due to different tyre diameters, and compensates for the difference.
