A control system for a vehicle including a power transmission system and a switching device has an electronic control unit configured to make a door open-close determination as to whether a door of the vehicle is open or closed, using an open-close signal indicating opening or closing of the door, and execute automatic parking control by causing the switching device to switch the power transmission system to the parking state, when the door open-close determination indicates that the door is open, while the vehicle is stopped with the power transmission system placed in the non-parking state. The electronic control unit determines that the door is open, when the open-close signal generated from at least one of a plurality of sensors provided for the same door changes from a close signal to an open signal.

A computer is programmed to determine an occupancy status of a vehicle based on received sensor data; and adjust a parameter of a powertrain of the vehicle in response to data indicating a critical condition of the powertrain based on the occupancy status. The parameter may be one of engine speed, cylinder deactivation, transmission-shift time, and shift schedule.

A transmission control system, which is adapted to be installed in a vehicle body of a two-wheeler, includes a transmission assembly, a mobile device and a transmission controller. The transmission assembly is configured to be disposed on the vehicle body and to perform a gear-shifting operation. The mobile device is configured to be detachably disposed on the vehicle body. The mobile device includes an orientation sensor capable of detecting a current center-of-gravity of the vehicle body to generate a current center-of-gravity datum. The transmission controller is configured to be disposed on vehicle body, to receive the current center-of-gravity datum, to calculate a roll angle variation according to the current center-of-gravity datum, and to output a gear-shift control command according to the roll angle variation. The transmission controller is configured to indicate the transmission assembly whether to perform the gear-shifting operation according to the gear-shift control command.

A column-mounted shifter for a transmission includes a housing adapted to mount on a steering column and a shaft supported for rotation within the housing. A lever is operably coupled to the shaft and extends radially therefrom. The lever is pivotal between a series of positions corresponding to a series of modes of the transmission. Rotation of the lever causes rotation of the shaft within the housing. A sensor is configured to sense rotation of the shaft and output a signal indicative of the position of the lever. An actuator arrangement is connectable with the shaft and is configured to rotate the lever from one of the positions to another of the positions.

A rotary shifter with 360 rotation in each of clockwise and counter clockwise rotating directions. The shifter includes a package housing with a bezel cover. A cylindrical shaped plunger housing is secured to a rotary knob supported atop the housing and which is selectively rotatable in the clockwise direction from a Park gear position, in succession, to each of a Reverse gear position, a Neutral gear position and at least one Drive gear position, with further clockwise rotation preventing movement beyond a final one of the Drive gear positions. The knob is further selectively rotatable in a counter clockwise direction to return to the Park gear position, with additional permitted counter-clockwise rotation retaining the shifter in the Park gear position.

An in-vehicle controller includes processing circuitry. The processing circuitry stops injection of fuel under a preset fuel cutoff condition including a lockup clutch being in an engagement state. A request for raising heating performance of a heater core is a heater actuation request, and an amount of particulate matter deposited on a filter is a deposition amount. The processing circuitry controls the lockup clutch in a disengagement state when a heater actuation request is generated and the deposition amount is less than a preset deposition amount threshold. The processing circuitry controls the lockup clutch in the engagement state when the heater actuation request is generated and the deposition amount is greater than or equal to the preset deposition amount threshold.

A shift control device includes: a stepless shift controller executing a stepless shift mode and controlling a transmission gear ratio of a continuously variable transmission in a stepless fashion; a stepped shift controller executing a stepped shift mode and controlling the continuously variable transmission using fixed transmission gear ratios; a mode setting unit switching the shift mode to the stepped shift mode when a vehicle is to be accelerated; and a transmission-gear-ratio setting unit setting an initial transmission gear ratio in the stepped shift mode when the shift mode is to be switched to the stepped shift mode. The transmission-gear-ratio setting unit estimates a variation in an engine rotation speed when the shift mode is to be switched to the stepped shift mode, and sets a fixed transmission gear ratio, at which the variation is greater than or equal to a lower limit value, as the initial transmission gear ratio.

A vehicle propulsion system includes an oncoming condition sensor that generates an oncoming condition signal, a continuously variable transmission with a variator assembly adapted to transfer torque between a first rotating member and a second rotating member through a flexible continuous device rotatably coupling the first rotating member to the second rotating member, one of the first rotating member and second rotating member including a clamping pulley adapted to controllably adjust a clamping force on the flexible continuous device, and a controller in communication with the oncoming condition sensor and the continuously variable transmission that is programmed to characterize an oncoming condition based upon the oncoming condition signal and to control the clamping pulley to adjust the clamping force based on the characterization of the oncoming condition.
