The improvement of the present invention is adaptable to an infinitely variable transmission that is controlled by a microprocessor with closed loop control of the speed ratio and torque converter slip. When the torque converter clutch is locked up, turbine speed is the same as the engine speed. ...
A system and method of compensating for torque converter slip in a motor vehicle include measuring rotational speeds of an engine crankshaft and mainshaft, as well as measuring oper
A lock-up mechanism for a torque converter for an automatic transmission is arranged to be selectively engaged to directly connect the output shaft and the input shaft of the torque converter when the
A torque limiting system for use in power driven equipment in which the power is applied through a torque converter to a drive train. The system utilizes a signal which is proportional to converter ou
the control system for the torque converter clutch causes slippage of the clutch to occur before the engine r.p.m. drops below a predetermined amount during rapid deceleration, such as during braking, even during low temperature operation to prevent engine stall that would otherwise occur when the...
threshold level; for example about 7% for vehicles with automatic torque converter transmissions. Below this threshold, powertrain creep torque is sufficient to counteract a negative road gradient load on the vehicle such that the vehicle begins to move forward once the driver actuated brake is ...
