An information processing device mounted on a vehicle including a sensor includes an acquisition unit that acquires a surrounding image of the vehicle and information related to a behavior of the vehicle from the sensor, and an identification unit that identifies a moving object in the surrounding image of the vehicle based on a chronological change of the surrounding image of the vehicle and the information related to the behavior of the vehicle.

Information processing device, system, and method

An information processing device that performs communication via a network includes: a storage unit that stores a receiving unit that receives data acquired by a device; the data; and past data received by the receiving unit before the data; a calculating unit that calculates a delay time in the network; a determination unit that determines, based on the calculated delay time, one or more past data used for prediction of future data that is not received by the receiving unit from the past data stored in the storage unit; and a predicting unit that predicts the future data using the determined past data.

In a drive assembly of the invention, a first catch tank is provided above a casing that keeps lubricating oil accumulated in a bottom thereof for immersion of part of a rotor of a motor MGand of part of a differential ring gear of a differential gear. The first catch tank temporarily keeps the lubricating oil scooped up from the bottom of the casing by the rotation of the differential ring gear. The lubricating oil kept in the first catch tank is flowed down by the force of gravity and is fed to peripheral bearings. A second catch tank is arranged to temporarily keep the lubricating oil scooped up from the bottom of the casing by the rotation of the rotor of the motor MG. The lubricating oil kept in the second catch tank is flowed down by the force of gravity and is fed to peripheral bearings. This arrangement desirably shortens oil paths connecting the respective catch tanks to the peripheral bearings and ensures smooth supply of the lubricating oil to all the peripheral bearings and other oil-requiring sites.

A curvature of a locus of contact points at a higher torque value is increased such that the torque-dependent characteristic of the working transmission error assumes a minimum value in the vicinity of a working torque value T.sub.1 at the tooth surface position corresponding to the working torque value T.sub.1, in the vicinity of a working torque value T.sub.3 at the tooth surface position corresponding to the working torque value T.sub.3, and in the vicinity of a working torque value T.sub.5 at the tooth surface position corresponding to the working torque value T.sub.5. As a consequence, the change in the working transmission error at the working torque is minimized making it possible to reduce the working transmission error in a wide working torque range.
