OSTI ID:5543234
An improved system is described for controlling a power transmission of a four-wheel drive vehicle powered by an engine having a transmission for transmitting the power of the engine to main driving wheels of the four-wheel drive vehicle, a clutch for transmitting the power to auxiliary driving wheels, circuit means for operating the clutch in accordance with driving conditions. The improvement described here consists of: first sensors for detecting speeds of the main and auxiliary driving wheels; a second sensor for detecting depression of an accelerator pedal of the vehicle; a thrid sensor for detecting depression of a brake pedal of the vehicle; a fourth sensor for detecting a neutral position and a parking position of a shift lever of the transmission; first means responsive to a large difference between the speeds of the wheels for engaging the clutch; second means responsive to large acceleration and large deceleration dependent on the output of the first sensors for engaging the clutch respectively.
