Title:
FRONT WHEEL ROTATION DRIVING CONTROL DEVICE FOR FOUR-WHEEL DRIVE TYPE MOVING VEHICLE
Document Type and Number:
Japanese Patent JP3136893
Kind Code:
B2
Abstract:
PURPOSE: To carry out control in response to a ground surface condition by switching the control to turning control when a steering angle reaches a prescribed value or more, switching it to rectilinear movement control when the steering angle does not reach the prescribed value, and switching it to full turn control or small steering angle turning control according to a change in rotating speed of rear wheels after being switched to the turning control.
CONSTITUTION: Signals of rear and front shaft rotation sensors 9 and 10 and a steering angle sensor 11 are inputted to a CPU13, and when the steering angle sensor 11 detects a prescribed value or more, 'turning control F' is carried out, and when a steering angle does not reach the prescribed value or more, 'rectilinear movement control G' is carried out. After being switched to the 'turning control F', control is switched to full turn control or small steering angle turning control according to a change in a detecting value of the rear shaft rotation sensor 9. Thereby, since the control is carried out in response even to a change after that by selecting prescribed control from plural control operations by a control means, the control operation can be carried out speedily while having a large number of controls.
