    Abstract: Transmission systems are disclosed which include a dual sunwheel system having an output sunwheel (70) and a control sunwheel (80). A planet cage is arranged around the dual sunwheel system and includes a planet gear (62) in mesh with the sunwheel (70) and a planet gear (64) in mesh with the sunwheel (80). The planet gears (62) and (64) are coupled to one another. The drive ratio of the transmission is controlled by controlling the cage (18) or the control sunwheel (70). The speed of rotation of the input, output and control sunwheel (70) are sensed by sensors (90) and control signals are generated to control a control device to thereby control the rotation of the input cage or the control sunwheel to thereby set the drive ratio of the transmission. The control devices include a motor (323), one or more magnetic powder clutches (110, 120, 640), a variable centroid system (662), and a mechanical pitch transfer gear system (950).

    Abstract: A controller for an electric four-wheel-drive vehicle, which can ensure smooth running performance of the vehicle, an electric driving system, and an electric four-wheel-drive vehicle using the controller. A first wheel is driven by an engine, a second wheel is driven by a motor, and a driving force of the engine is transmitted to the first wheel through a manual transmission and a clutch. When the clutch is in a partially engaged state, a controller (4WDCU) receives an input signal representing a degree of engagement of and clutch and outputs a signal to control a driving force of the motor in accordance with the input signal. When the vehicle starts running and no slips occurs in the wheels, the 4WDCU outputs the signal to gradually increase the driving force of the motor as the engagement of the clutch is progressed.

    Abstract: An apparatus for controlling the rate of engagement of a clutch in response to an indication provided by the driver, such as the depression of an accelerator pedal of the vehicle. The apparatus includes an electronic controller which initially determines a start rate as the minimum duty cycle which is required to modulate an engage valve in order to cause movement of a release bearing of the clutch in the engagement direction. The start rate is determined by initially moving the release bearing to the disengaged position. Then, the engage valve is modulated incrementally modulated until the release bearing begins moving in the engaged direction from the disengaged position. When a predetermined amount of such movement has been detected, the electronic controller sets the start rate as the current duty cycle of the engage valve. The electronic controller is also responsive to an excessive amount of overshooting movement of the release bearing when attempting to position it in a desired position for reducing the start rate.

    Abstract: A transfer case includes an input shaft, an output shaft, and a gear set selectively operable to translate torque between the input and output shafts at reduced speeds. A clutch is operable to translate torque between the input and output shafts either directly or through the gear set. An actuator, having a rotational output, is operatively coupled to the clutch for moving the clutch between predetermined positions. A control unit is employed in connection with the transfer case to effect the method of synchronizing low to high shifts in the transfer case. To this end, the control unit calculates the speed of the actuator as it moves the clutch to a neutral position. The control unit further determines the additional time until the clutch will reach a predetermined synchronization point using the speed of the actuator and the remaining rotational distance through which the actuator must move for the clutch to reach the predetermined synchronization point. The control unit is further operable to stop the actuator when the clutch has reached the synchronization point for no longer than a predetermined time. The control unit then senses and compares the rotational speeds of the input and output shafts and signals the actuator to complete the shift from low to high by moving the clutch to provide direct torque translation between the input and output shafts when the difference in the rotational speeds of the input and output shafts is less than a predetermined value.

    Abstract: An apparatus and method for controlling the engagement rate of a clutch in a partially or fully automated mechanical transmission is responsive to certain calculations derived from the rotational speeds of the input member and the output member of the clutch. The apparatus includes an electronic controller which initially sets a desired speed for the vehicle engine during the shifting process, determines a rate of engagement movement of a release bearing of the clutch, and actuates appropriate valves to initiate the gradual engagement of the clutch. In a first embodiment, the electronic controller compares the rotational speeds of the input and output shafts of the clutch in order to determine if the difference therebetween is less than a first constant value. If so, it can be inferred that the clutch is sufficiently close to full engagement as to warrant the interruption the gradual engagement process and immediately move the release bearing from its current position to the fully engaged position. To avoid a false inference of full engagement, the clutch input or output shaft speed signal is compared with the desired engine speed signal. When the magnitude of the difference between the clutch input shaft speed signal and the desired engine speed signal is less than a second constant value, then the inference that the clutch is sufficiently close to full engagement is confirmed. Thus, the release bearing can be immediately moved from its current position to the fully engaged position. In a second embodiment, an updated difference signal (calculated as the difference between an updated clutch input shaft speed signal and an updated clutch output shaft speed signal) is compared with a previous difference signal. An error signal is calculated as the difference between the updated difference signal and the previous difference signal. The electronic controller controls the movement of the release bearing such that the error signal closely follows a selected clutch engagement profile so as to consistently engage the clutch.

    Abstract: A method for learning a clutch pedal may include determining whether a clutch pedal is operated; determining at least one of a depressed speed of the clutch pedal, a depressed value of the clutch pedal, and a speed of an engine at a shifting timing when the clutch pedal is operated; determining at least one of a moving average value of the depressed speed of the clutch pedal, a moving average value of the depressed value of the clutch pedal, and a moving average of the speed of the engine for a predetermined time; and storing the moving average value as a correction value for preventing an abrasion of a shift clutch.
