A slip control method and arrangement for a driveline including a continuously variable transmission is described herein. The driveline 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.

A shift change practice device capable of improving the effect of learning a shift change operation is provided. The shift change practice device includes: an optimum speed calculation unit that calculates an optimum value or an optimum range of an engine revolution speed in the event of a shift change; a revolution speed comparison unit that determines whether or not a detected revolution speed that is a detected value of the engine revolution speed is equal to the optimum value or whether or not the detected revolution speed is included in the optimum range, in a state where a clutch is disconnected; and a notification instruction unit that instructs a notification device to give a predetermined notification to a driver when the detected revolution speed is equal to the optimum value or the detected revolution speed is included in the optimum range, in the state where the clutch is disconnected.

A vehicle includes a transmission having a first neutral with a first combination of engaged clutches and a second neutral with a second combination of engaged clutches. The second neutral has more engaged clutches than the first neutral. A vehicle controller is programmed to, in response to a request to shift from the first to the second neutral and a failed-on clutch being detected, inhibit the shift to remain in the first neutral.

A vehicle includes a transmission having a first neutral with a first combination of engaged clutches and a second neutral with a second combination of engaged clutches. The first neutral has more engaged clutches than the second. A controller is programmed to, in response to a request to shift from a drive gear to the first neutral and a clutch of the drive gear being failed-on, shift to the second neutral.

A shift control device includes: a selector configured to receive operation of selecting a shift range of an automatic transmission and output selection information corresponding to the operation, the automatic transmission being configured to convert and output driving force of an engine; a range switch controller configured to switch the shift range in accordance with the selection information; a parking mechanism configured to bring the automatic transmission into a parking state by locking rotation of the automatic transmission; a clutch configured to turn on/off transmission of driving force; a clutch controller configured to control operation of the clutch in accordance with the selection information; and a delay setter configured to set delay time until driving of the parking pawl starts on the basis of rotation speed difference and oil temperature of the automatic transmission when selection information indicating that the parking range is selected is output.

Vehicles, systems, and methods for shifting a manual transmission into neutral during autonomous braking are provided. An exemplary system for shifting a vehicle into neutral during autonomous braking includes a manual transmission for transferring power from an engine to a differential using gears manually selected by a gear selector. Also, the system includes an actuator mounted to the vehicle and to the gear selector. Further, the system includes a controller coupled to the actuator and configured to direct the actuator to force the gear selector into neutral during an autonomous braking event.

The invention relates to a method for improved gear shifting of a vehicle having an Otto-engine and a vehicle transmission with a manually actuated clutch of the vehicle transmission, comprising the steps of: determining a first set of condition parameter values, said parameters comprising clutch position, requested engine torque and engine speed; determining if the first set of condition parameter values meet first predetermined conditions; if the first predetermined conditions of said first set of condition parameter values are met, activating a function for interrupting fuel provision of the engine before disengaging the vehicle transmission during gear shifting. The invention also relates also to system and a computer program product for implementing the method and a motor vehicle equipped with the system.
