    Abstract: Method for controlling the claw coupling of two gearbox elements initially rotating at different speeds when the driver or the box computer requests claw coupling, characterized in that, in a first phase, the difference in rotational speed of the rotary elements is brought by a regulator to a non-zero reference value without any translational movement of the rotary elements toward one another, and in that the movement of the rotary elements until they are claw-coupled occurs in a second phase that begins when the difference in rotational speed reaches its desired value, during which phase the difference perceived by the regulator is modulated by a factor (F) that is a function of the raw difference between the measured value and the reference value.

    Abstract: When a synchronizing sleeve that is driven by an actuator in response to gear shift request is stroked from a release position to an engagement position, a differential rotation speed between an input rotation and an output rotation is calculated at stroke positions after a synchronization completion position; and when the said differential rotation speed is equal to or more than a predetermined threshold value, a damage determination index is calculated based on the said differential rotation speed. Further, when a cumulative value of the damage determination index accumulated for each gear position becomes equal to or more than a predetermined threshold value, the engagement operation of the gear position corresponding to the said cumulative value is disabled. This makes it possible to effectively determine the degree of damage when a gear whine occurs to a synchronized engaging device.

    Abstract: A method for diagnosing damage in the shift mechanism of an automatic gearbox, involving at least one of the following steps: (a) determining an actual period needed for synchronizing a gear, comparing the actual period with a setpoint period for synchronizing the gear, and establishing whether the shift mechanism is damaged; the shift mechanism is assumed to be damaged if the actual period differs from the setpoint period; (b) moving a shift actuator to a limit stop after selection of a gear, establishing whether the limit stop that has been reached is an internal limit stop of the shift actuator or a gearbox limit stop, and establishing whether the shift mechanism is damaged; the shift mechanism is assumed to be damaged if the limit stop that has been reached is an internal limit stop of the shift actuator; (c) determining an actual engine speed during the overlap phase and comparing the actual speed with a speed range within which the engine speed is expected to lie during the overlap phase, and establishing whether the shift mechanism is damaged; the shift mechanism is assumed to be damaged if the actual speed is not within the range for the expected speed.

    Abstract: A method of shifting a vehicle drive-train transmission having frictional and interlocking shifting elements which are engageable to obtain various gears. When shifting from a current gear to a target gear, in which the interlocking shifting element is engaged, if after the shift starts it becomes necessary to engage the current gear in the transmission while engaging the interlocking shifting element, a current operating condition of the interlocking shifting element is determined. If the current operating condition of the interlocking shifting element indicates that engagement can be interrupted and the interlocking shifting element can be disengaged, the interlocking shifting element is disengaged. If the current operating condition of the interlocking shifting element indicates that engagement of the interlocking shifting element has to be carried out and the interlocking shifting element engaged, then the interlocking shifting element is engaged and/or the force flow in the transmission device is interrupted.

    Abstract: A road slope estimating device which is mounted on a vehicle and estimates a slope of a road on which the vehicle is traveling, the vehicle including a motor and a transmission capable of changing a shift speed by an engagement switching operation of disengaging one of a plurality of engagement elements and engaging another one of the plurality of engagement elements, and outputting power from the motor via the transmission to travel. An estimating section carries out first road slope estimation from the computed output torque and acceleration of the vehicle until transfer of torque is handed over from the engagement element to be disengaged of the plurality of engagement elements to the engagement element to be engaged. Second road slope estimation is estimated from the computed output torque and the acceleration of the vehicle when the handover of the transfer of torque is carried out.
