Filed: 1985-09-26
Abstract: PURPOSE:To insure an operator against forgetting the preservation of a generated document by automatically terminating work generating documents and preserving the generated ones on a document file when an input device is not operated over the prescribed period in the middle of generating documents. CONSTITUTION:During generating documents, the status of a keyboard 1 is checked.

Abstract: PURPOSE:To aim at preventing a spin due to a slip from occurring, by installing each revolving speed detecting device for both front and rear wheels, and a controlled variable setting device, setting a controlled variable which steers rear wheels according to the speed difference as well as an outputting device. CONSTITUTION:A car speed U is calculated out of a car speed sensor 51a by a central processing unit 52b and stored in a random access memory 52c, while a revolving speed data is stored into the RAM 52c by wheel revolving speed sensors 51b-51e. A smaller side of a front-wheel revolving speed is subtracted from a larger side of a rear-wheel revolving speed on the basis of the revolving speed data by the CPU 52b whereby a speed difference (g) is calculated and stored into the RAM 52c. Next, a car speed corresponding steering angle ratio K is calculated by the steering angle ratio pattern data stored in a read-only memory 52a on the basis of the car speed data by the CPU 52b, adding a functional value (f) to be increased in proportion as this speed difference (g) increases, thus the desired steering angle ratio K+f is calculated. With this constitution, steering control takes place as the same phase or opposite phase to front wheels according to a slip state in rear wheels so that a spin due to a slip is prevented from occurring without fail.
