Title:
FOUR WHEEL STEERING DEVICE FOR VEHICLE
Document Type and Number:
Japanese Patent JPS628869
Kind Code:
A
Abstract:
PURPOSE:To allow a slip angle of a vehicle to be zero at all times regardless of a change of torque distribution by configurating a device in such a way that the characteristics of a steering angle ratio is corrected in response to a change of torque distribution to both a front and a rear wheel, and the steering angle ratio is variably controlled by the said corrected characteristics. CONSTITUTION:The actuation of both a pulse motor 14 and a drive motor 24 for a hydraulic pump 25 is controlled by signals outputted from a controller 25 that is a control section of a rear wheel steering mechanism 7. Following signals are inputted into the controller 25: they are a steered angle signal from a steering angle sensor 26, a vehicle speed signal from a vehicle speed sensor 27, and an output signal from a torque distribution detecting means 26 which detects the torque distribution to both a front and a rear wheel which is effected by a variable torque distribution mechanism. The controller 25 includes a means which corrects a steering angle ratio upon receiving of an output signal from the torque distribution detecting means 28, in such a way that a slip angle of a vehicle is zero at all times in response to a change of torque distribution to both the front and rear wheels which is effected by the variable torque distribution mechanism.
