A control apparatus for a vehicle having a step-variable transmission. The control apparatus includes: a shift control portion to temporarily increase an input torque of the step-variable transmission beyond a required value, the shift control portion commanding an engaging-side coupling device which is the coupling device placed in a released state, to be brought into an engaged state, when the input speed has been raised to a predetermined value; and a torque increasing amount setting portion to set an amount of increase of the input torque of the step-variable transmission beyond the required value, such that the amount of increase is smaller when a rate of change of a running speed of the vehicle is relatively low than when the rate of change is relatively high, the rate of change of the running speed having a negative value in a decelerating state of the vehicle.

An apparatus comprising an interface, a memory and a processor. The interface may be configured to receive sensor data samples during operation of a vehicle. The memory may be configured to store the sensor data samples over a number of points in time. The processor may be configured to analyze the sensor data samples stored in the memory to detect a pattern. The processor may be configured to manage an application of brakes of the vehicle in response to the pattern.

A working vehicle comprises: a vehicle body; a linkage device configured to link a working device to the vehicle body; a prime mover provided on the vehicle body; a traveling device configured to cause the vehicle body to travel; a transmission device configured to transmit power from the prime mover to the traveling device and perform a speed change process to change a speed of the vehicle body; an increase-in-speed detection device configured to detect an increase in speed of the vehicle body; and a speed change restraint unit configured such that, during the speed change process performed by the transmission device, when the increase in speed detected by the increase-in-speed detection device has become equal to or greater than a threshold, the speed change restraint unit stops the speed change process performed by the transmission device.

A method for operating a vehicle drive train (1) includes, during a downshift, disengaging at least one shift element (A through F) from a power flow of the transmission (5), guiding a power transmission capacity of a torque converter lockup clutch (4) to a level at which the torque converter lockup clutch (4) is in a non-slip operating condition during a positive engine override when a rotational speed of a prime mover (2) is guided towards a synchronous speed of a demanded desired ratio, and guiding the power transmission capacity of the torque converter lockup clutch (4)—no later than a point in time of the downshift at which the rotational speed of the prime mover (2) is equal to the synchronous speed of the desired ratio—to a level at which the torque converter lockup clutch (4) is transferred into a continuous slip operation due to torque.

A control apparatus for a vehicle that includes an engine; a transmission; a damper and a clutch. The transmission has a gear ratio that is variable in a range including a torque-fluctuation insufficient absorption region in which a damper spring of the damper is elastically deformed to a certain maximum limit when a misfire occurs in the engine. The control apparatus includes: a misfire determination portion configured to determine occurrence of the misfire in the engine; and a misfire-case shift control portion configured, upon determination of the occurrence of the misfire in the engine by the misfire determination portion when the gear ratio of the transmission is in the torque-fluctuation insufficient absorption region, to cause the transmission to execute a shift-down action such that the gear ratio becomes higher than a higher threshold value of the torque-fluctuation insufficient absorption region.
