Title:
CONTROL METHOD AND DEVICE FOR AUTOMATIC CLUTCH OF VEHICLE
Document Type and Number:
Japanese Patent JPS6246724
Kind Code:
A
Abstract:
PURPOSE:To facilitate hill start operation through simple structure by regulating the transmission torque of automatic clutch on the basis of gradient of road under such stopping condition as can be started immediately through accelerat ing operation. CONSTITUTION:Under operation of vehicle, output signals from rotary speed sensor 34, vehicle speed sensor 38, shift position sensor 42, acceleration pedal sensor 48 and brake pedal sensor 50 are fed to a controller 36. Under stopping condition of vehicle having zero vehicle speed where the shift lever is not in the neutral position and the brake pedal or the accelerating pedal is not stepped, the controller 36 will calculate the basic clutch transmission torque on the basis of the output from a gradient sensor 51. In accordance to said torque, the transmission torque of automatic clutch 12 comprising a magnetic powder electromagnetic clutch is regulated and upon detection of backing of wheel, the transmission torque is increased by predetermined amount.
