First Claim
Patent Images
1. A control system for controlling an automotive clutch, comprising:
- a power transmitting path extending from an engine to a driven system;
clutch means disposed in said power transmitting path for controlling transmission of power from the engine through the power transmitting path to the driven system;
a clutch actuator for controlling said clutch means selectively for engagement and disengagement;
control means for controlling said clutch actuator to engage said clutch means in a feedback loop at variable engine speeds such that a torque transmitted through said clutch means is equal to an engine output torque when the power from said engine starts to be transmitted through said power transmitting path by said clutch means.

Abstract
An automatic transmission on an automobile is combined with a friction clutch coupled between the output shaft of an engine and the input shaft of the automatic transmission. The friction clutch is controlled selectively for engagement and disengagement by an electric actuator. The electric actuator is controlled by a controller to engage the friction clutch in a feedback loop such that the rate of change of the rotational speed of the engine is zero when the power from the engine starts to be transmitted by the friction clutch to the automatic transmission.

3. A control system for controlling an automotive clutch, comprising:
-
a power transmitting path extending from a drive unit to a driven system; clutch means disposed in said power transmitting path for controlling transmission of power from the drive unit through the power transmitting path to the driven system; a clutch actuator for controlling said clutch means selectively for engagement and disengagement; detecting means for detecting a rate of change of a rotational speed of the drive unit; and control means for controlling said clutch actuator to engage said clutch means in a feedback loop such that said rate of change of the rotational speed of the drive unit is zero when the power from said drive unit starts to be transmitted through said power transmitting path by said clutch means. - View Dependent Claims (4, 5, 6)
