Abstract

[Problem] To reduce the time during which both a rotational torque and an actuator thrust act on a bearing. [Solution] This transmission device comprises: a first planetary gear mechanism; a second planetary gear mechanism; a first fastening mechanism; a second fastening mechanism; and a third fastening mechanism. The third fastening mechanism includes: a pressing part that fastens a fastening element; a spring that biases the pressing part in a fastening direction; an actuator that generates thrust in a release direction and that releases the fastening element by using the thrust to displace the pressing part in the release direction; and a bearing that, when the fastening element is to be released, receives the load of the spring compressed by the thrust. In a first speed-changing step, the transmission device fastens the first fastening mechanism and releases the second fastening mechanism and the third fastening mechanism, and in a second speed-changing step, the transmission device fastens the second fastening mechanism and releases the first fastening mechanism and the third fastening mechanism. The first speed-changing step is selected during emergency travel, which requires a larger driving force than during a normal start.

Abstract

A control device and method controls a vehicle having an internal combustion engine connected to an automatic transmission via a torque converter with a lockup device. The torque of the internal combustion engine is limited the by a torque limit value based on a speed difference between an input rotational speed and an output rotational speed of the torque converter during acceleration in a non-lockup state. The torque-limiting of the internal combustion engine is prohibited torque-limiting upon a prescribed condition being met. The prescribed condition is met by a heating request, during hill climbing/towing, during travel at high vehicle speeds, when the accelerator pedal opening angle exceeds or is equal to a prescribed opening angle, when the torque limit value is greater than a target torque, in a range other than a D range, or in a mode other than normal mode.
