Abstract
Abstract An automatic control system for operating the clutch of a car and capable of being attached to cars of manual shift transmission type comprising a servomotor mechanism positively and reversely rotated depending upon increase and decrease of supplied voltage to drive a clutch pedal in direction in which a clutch is connected and disconnected; a circuit for converting the rotation number of engine to a pulse output to detect the rotation number of engine; a frequency-voltage converter circuit for supplying to a servomotor an output voltage responsive to said pulse output; and a switching means connected on the way of a voltage supply line extending from the frequency-voltage converter circuit to the servomotor mechanism and changing voltage supplied to the servomotor mechanism by manual or foot operation to positively and reversely rotate the servomotor mechanism.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
132 words
An automatic control system for operating the clutch of a car and capable of being attached to cars of manual shift transmission type comprising: a servomotor mechanism positively and reversely rotated depending upon increase and decrease of supplied voltage to drive a clutch pedal in directions in which a clutch is connected and disconnected; a circuit for converting the rotation number of engine to a pulse output to detect the rotation number of engine; a frequency-voltage converter circuit for supplying to a servomotor an output voltage responsive to said pulse output; and a switching means connected on the way of a voltage supply line extending from the frequency-voltage converter circuit to the servomotor mechanism and changing said supplied voltage by manual or foot operation to positively and reversely rotate the servomotor mechanism.
Claim 2
Dependent Claim
132 words
An automatic control system for operating the clutch of a car and capable of being attached to cars of manual shift transmission type comprising: a servomotor mechanism positively and reversely rotated depending upon increase and decrease of supplied voltage to drive a clutch pedal in directions in which a clutch is connected and disconnected; a circuit for converting the rotation number of engine to a pulse output to detect the rotation number of engine; a frequency-voltage converter circuit for supplying to a servomotor an output voltage responsive to said pulse output; and a switching means connected on the way of a voltage supply line extending from the frequency-voltage converter circuit to the servomotor mechanism and changing said supplied voltage by manual or foot operation to positively and reversely rotate the servomotor mechanism.
Claim 3
Dependent Claim
55 words
An automatic control system for operating the clutch of a car according to claim 1 wherein said switching means comprises a resistor connected in series to the voltage supply line and a contact connected parallel to the resistor and turned on and off by a manual operation switch which is arranged on a shift Lever.
Claim 4
Dependent Claim
50 words
An automatic control system for operating the clutch of a car according to claim 1 wherein said switching means comprises a resistor connected in series to the voltage supply line and a contact connected parallel to the resistor and turned on and off by foot operation of an accelerating pedal.
Claim 5
Dependent Claim
68 words
An automatic control system for operating the clutch of a car according to claim 1 wherein said switching means comprises a resistor connected in series to the voltage supply line, a contact connected parallel to the resistor and turned on and off by operation of the accelerating pedal, and another contact connected parallel to the resistor and turned on and off by foot operation of a brake pedal.
Claim 6
Dependent Claim
41 words
An automatic control system for operating the clutch of a car according to claim 1, 2, 3 or 4 wherein a limit switch is arranged on the back side of said clutch pedal to interrupt voltage supplied to the servomotor mechanism.
Claim 7
Dependent Claim
50 words
An automatic control system for operating the clutch of a car according to claim 1, 2, 3 or 4 wherein the rotation number of engine can be set to an optional one by presetting the frequency-to-voltage converting ratio in the frequency-voltage converter circuit when the clutch is to be connected.
