A controller includes: an automatic shifting control section that carries out automatic shifting control in which a shifting actuator is driven in response to a predetermined automatic shifting command; and an interference prevention control section that controls the automatic shifting control section so as to prohibit simultaneous occurrence of a manual shifting process induced by operation of a shifting operation member and an automatic shifting process induced by the shifting actuator.

In a vehicle having a continuously variable transmission, a controller selectively performs a first control mode in which a transmission ratio is controlled in a stepless manner, and a second control mode in which the transmission ratio is controlled in a stepwise manner to perform an upshift after a vehicle speed has increased. When the second control mode is selected in response to a driver's acceleration request, the controller continuously downshifts the transmission ratio until the upshift is performed.

A motor vehicle includes an engine having, in an exhaust system thereof, a particulate matter removal filter that removes particulate matters, a shift device capable of performing a sequential shift operation, and an electronic control unit that controls the engine such that the motor vehicle runs in accordance with a driver's operation. The electronic control unit is configured to perform control in such a manner as to cause the vehicle to run without carrying out a shift even when the sequential shift operation is performed by the driver, if a deposition amount of particulate matters deposited in the particulate matter removal filter is equal to or larger than a predetermined amount. Thus, the particulate matter removal filter can be restrained from being overheated through the supply of a large amount of air to the particulate matter removal filter with the predetermined amount or more of particulate matters deposited therein.

A method for operating a motor vehicle, in particular a passenger vehicle, having at least one drive engine and an automatic transmission. A motor vehicle with conventional shift transmission is imitated by providing a clutch pedal for separating the drive connection, a shift lever for the manual shifting of the gear ratios, and an electronic control unit, by which the functions of clutching and shifting are converted into corresponding control signals for the automatic transmission.

A method for transmitting a shift signal of an electronic shift system, may include transmitting the shift signal generated at the time of operating a shift operation device, wherein the shift operation device is configured so that one shift stage and one shift signal are matched one to one and transmits shift signals which are each individually separated according to the shift stage.

Methods and systems are provided for an actuation system for a driveline shifting member in a transmission system of a vehicle. In one example, a system may include an actuator coupled to a lever arm via one or more parallel axis gears, and a shaft connecting the lever arm to a driveline shifting member, the lever arm driven via a rolling element housed within a slot in the lever arm aligned with a center of a parallel axis gear of the one or more parallel axis gears.

A paddle shifter includes a pair of operation portions that decrease or increase the deceleration, the shift characteristic of the vehicle is set to a fixed shift mode based on the operation of the driver in response to an operation of one operation portion, a shift characteristic of the vehicle is set to a fixed shift mode based on the operation of the driver in response to an operation of the one operation portion, the shift characteristic of the vehicle is set to an automatic shift mode based on a running condition of the vehicle in response to an operation of the other operation portion, and when the one operation portion of the pair of operation portions remains in an ON state for a predetermined period of time, a change in the shift characteristic of the vehicle based on the other operation portion is activated.
