    Abstract: A vehicular breaking force control system that includes a control device including a processor that acquires a plurality of longitudinal accelerations from a driving assistance system, and calculates a driving/braking request when the vehicle is in a coasting state in which an acceleration operation or a deceleration operation are not performed during running of the vehicle. The processor further acquires a driving force lower limit set for a powertrain actuator having a set gear ratio, and distributes the driving/braking request to at least one of (i) a powertrain system including the powertrain actuator and (ii) a brake system including a brake actuator. The driving/braking request is distributed to the at least one of the powertrain system and the brake system based on the acquired driving force lower limit.

    Abstract: A first transmission mechanism provided on a first power transmission path and a second transmission mechanism provided on a second power transmission path are provided in parallel with each other between a driving force source and a drive wheel. A first clutch mechanism transmits power or interrupts transmission of power in the first power transmission path. A dog clutch equipped with a synchromesh mechanism transmits power or interrupts transmission of power in the second power transmission path. An electronic control unit is configured to, when changing from the first transmission path to the second transmission path a state where the vehicle is stopping or is stationary and in a state where power of the driving force source is transmitted via the first transmission mechanism, actuate the first clutch mechanism and the second clutch mechanism such that the first clutch mechanism is released and the second clutch mechanism engages.

    Abstract: When a rotation speed difference between rotary members of a mode switching clutch is equal to or less than a predetermined value during travel in a belt travel mode, there is a likelihood that the mode switching clutch would be secured to a lock mode in which power operating in two directions is transmitted. At this time, since switching to a gear travel mode is prohibited, it is possible to curb occurrence of a shock when power is simultaneously transmitted via a first power transmission path and a second power transmission path in a transition period of switching to the gear travel mode.

    Abstract: A vehicle transmission has a continuously variable speed change mechanism provided between an input shaft to which a torque output by a driving force source is transmitted and an output shaft from which a torque is output to a driving wheel. The transmission is able to selectively block torque transmission between the mechanism and the output shaft. The mechanism is rotated by the driving force source with torque transmission between the mechanism and the output shaft blocked. A control apparatus limits a shifting speed of the mechanism to or below an upper-limit speed determined in advance in a case where a speed ratio of the mechanism is changed with the mechanism rotated by the driving force source that is subjected to idling rotational speed control, while the mechanism is blocked from the output shaft such that no torque is transmitted between the mechanism and the output shaft.
