Abstract: A method may include identifying computing systems corresponding to an autonomous vehicle (AV) in which each computing system is configured to perform at least one operation relating to driving the AV. The method may include determining whether the computing systems use a first respective real-world parameter as an input to any of the operations or generate a second respective real-world parameter as an output of the operations. A respective operation corresponding to a respective computing system may be designated for accelerated performance based on the determination, and the operations of the computing systems may be performed. A first operation not designated for accelerated performance may include first computations corresponding to the first operation after waiting for a synchronization delay period, and a second operation designated for accelerated performance may include second computations corresponding to the second operation and performed without waiting for the synchronization delay period.

Abstract: The transmission control unit includes a gear ratio abnormality determination unit and a limp home control unit. The gear ratio abnormality determination unit is configured to determine that a gear ratio is abnormal when, during travelling at a predetermined gear position, a difference between an actual gear ratio, which is calculated based on a transmission input shaft rotation speed and a transmission output shaft rotation speed, and a set gear ratio at the predetermined gear position is equal to or greater than a set value. The limp home control unit is configured to, when the gear ratio abnormality determination unit determines that the gear ratio is abnormal, output a disengagement instruction for disengaging all of the plurality of friction elements, when it is confirmed that a neutral state is shifted to according to the output of the disengagement instruction, determine engagement/disengagement of a specific friction element among the plurality of friction elements based on rotation/stop information of a rotation member of the stepped transmission mechanism, and determine an evacuation gear position based on determination information on the engagement/disengagement of the specific friction element, and shift the gear position to the determined evacuation gear position.

Abstract: A machine may include an engine, a traction device, a continuously variable transmission (CVT) connecting the engine to the traction device, an operator input device outputting engine output command signals input by an operator, an engine speed sensor monitoring an engine output speed, and an electronic control module (ECM). The ECM controls a machine output of the machine by executing a transmission output control routine using transmission output parameters as feedback when transmission output parameter sensor signals are reliable. The ECM controls the machine output by executing a target engine speed control routine using an engine output speed sensor signals as feedback when the transmission output parameter sensor signals are nor reliable. In the target engine speed control routine, the ECM determines a CVT transmission ratio that will cause the CVT to apply a load to the engine that will cause the engine to run at the target engine speed.

Abstract: Disclosed are power machines, and drive systems for use thereon, as well as methods of controlling the displacement of a hydraulic drive motor. The drive system includes a drive pump capable of providing a hydraulic power output and a drive motor operably coupled to the drive pump that receives the hydraulic power output from the drive pump. The drive motor has an operating displacement that is variable between a minimum displacement and a maximum displacement and it provides a rotational output member. A shift actuator is operably coupled to the drive motor and it is configured to vary the displacement of the drive motor between the minimum displacement and the maximum displacement. A controller controls the shift actuator to cause the drive motor to provide infinitely variable displacement between the minimum and maximum displacements.

Abstract: A clutch disengagement position is detectable with high precision even during speed change. A vehicle transmission device can include a transmission including a main shaft to which rotational power from an engine is inputted via a clutch, and a countershaft, a clutch operation member that is driven by an actuator and performs disengaging and engaging operations of the clutch, and a driving wheel to which rotational power of the countershaft is transmitted via a driving force transmitting device. A damper member deformed by a driving force is provided in the countershaft, the driving force transmitting device or the driving wheel, or among the countershaft, the driving force transmitting device and the driving wheel. A control device learns a clutch disengagement operation amount when the control device detects deceleration of a predetermined value of the rotational frequency of the main shaft.
