Abstract: A method in a control arrangement of a vehicle and a control arrangement for a vehicle for downshifting gears in an uphill slope are presented. The method comprises, when the vehicle is travelling in an uphill slope using an initial gear of the vehicle's automated manual transmission gearbox: simulating at least one speed profile for a downshift to, and a usage of, at least one gear; determining that a minimal speed of each one of the at least one simulated speed profile has a value indicating that the actual speed of the vehicle will be less than or equal to zero in the uphill slope; opening a clutch before is reduced to a value less than zero; activating at least one vehicle brake; shifting vehicle's automated manual transmission gearbox to a start gear; closing the clutch; and deactivating the at least one vehicle brake.

Abstract: An apparatus comprising an interface and a processor. The interface may be configured to receive pixel data of an exterior environment of a vehicle. The processor may be configured to process the pixel data arranged as video frames, perform computer vision operations to detect objects in the video frames, extract characteristics about the objects detected, determine driving conditions in response to an analysis of the characteristics and generate a control signal. The control signal may be configured to perform a gear shift. The driving conditions may be used to predict a future drivetrain configuration of the vehicle. The gear shift may be performed if a comparison of the future drivetrain configuration with a current drivetrain configuration of the vehicle meets a threshold condition. The gear shift may not be performed if the comparison does not meet the threshold condition.

Abstract: A system includes a driveline, a user interface, and a control system. The driveline includes an engine, a transmission, and a clutch positioned to selectively couple the engine to the transmission. The user interface is configured to facilitate operator shifting of the transmission. The control system is configured to perform a transmission auto-shift procedure where the control system monitors engine speed of the engine for a period of time following completion of a downshift event with the transmission from a first, higher gear to a second, lower gear, compares the engine speed to at least one speed threshold, and automatically upshifts the transmission from the second, lower gear back to the first, higher gear (i) following expiration of the period of time and/or (ii) in response to the engine speed exceeding the at least one speed threshold during the period of time.

Abstract: A method for determining a drag torque coefficient of a transmission includes performing rotational speed synchronisation involving application of synchronisation torque to a first transmission component, and obtaining an initial rotational speed of the first transmission component before the rotational speed synchronisation, and a final rotational speed of the first transmission component after the rotational speed synchronisation, and time period for performing the rotational speed synchronisation. Also, obtaining information relating to a level of the synchronisation torque applied to the first transmission component during the rotational speed synchronisation, and information relating to a total moment of inertia associated with the first transmission component. In addition, determining the drag torque coefficient based on the obtained initial rotational speed, the obtained final rotational speed, the obtained time period, the level of the applied synchronisation torque and the total moment of inertia associated with the first transmission component.

Abstract: A slip control method and arrangement for a drivetrain including a continuously variable transmission, forward-reverse clutch arrangement and an optional three-speed gearbox is described herein. The forward-reverse clutch arrangement includes a clutch that is so controlled as to slip when a torque higher than the usable torque attempts to pass through. Accordingly, the clutch prevents the prime mover from stalling.
