Title:
MOTOR-DRIVEN TYPE POWER STEERING DEVICE
Document Type and Number:
Japanese Patent JPS62225458
Kind Code:
A
Abstract:
PURPOSE:To prevent oversteering of a handle and running down of a battery, by providing a torque sensor, detecting the rotation force of the handle, a car speed sensor, an acceleration sensor, a reduction sensor, a power generation sensor, detecting the power generating state of an alternator, and a battery sensor. CONSTITUTION:Oversteering of a handle 1 can be prevented from occurring in a way that, in relation to a change in the weight of the handle 1 during acceleration and reduction of a vehicle, through detection of an acceleration reduction state and a fact that a brake signal and an accel opening exceed a given value, a voltage applied on a motor 13 or the clutch current of a clutch 14 are reduced or limited to zero. A battery can be prevented from running down in a way that no power generation or defficiency in charging of a battery is detected by means of an alternator power generation sensor 21 and a battery sensor 22, and a voltage applied on a motor and the clutch current of an electromagnetic type slip clutch 14 are reduced or controlled to zero.
