Abstract: A route planner detects a pedestrian from surrounding data representing a situation of surroundings of a vehicle, identifies a position of a pause-by object in the surroundings of the vehicle prompting the pedestrian to pause, creating a travel route over which the vehicle will travel when the pedestrian is detected, assuming the pedestrian will enter a road on which the vehicle will travel when the identified position of the pause-by object is not in the vicinity of the pedestrian, and assuming the pedestrian will not enter the road when the identified position of the pause-by object is in the vicinity of the pedestrian.

Abstract: A motion prediction device detecting, from surrounding data representing a situation in a predetermined range of surroundings of a vehicle, a traffic participant existing in the predetermined range, determining whether there is a blind area not represented in the surrounding data in the predetermined range, when it is determined that there is a blind area presuming that there is a virtual traffic participant in the blind area, and predicting motion of the traffic participant caused by the presence of the virtual traffic participant.

Abstract: In a catch tank, a partition wall is formed that extends along a vehicle front-rear direction and divides the catch tank in a vehicle width direction in a vehicle-mounted state, which helps prevent oil in the catch tank from flowing unevenly to one of a first space and a second space even when the oil surface of the oil tilts during turn of the vehicle, for example. As a result, an appropriate amount of oil required for lubrication is supplied through a second lubrication hole regardless of tilt of the vehicle or turn of the vehicle.

Abstract: Provided is a manual release mechanism for a parking lock device including a gear, a meshing tooth capable of meshing with the gear, and an actuator that switches between a parking lock state and a non-parking lock state. The manual release mechanism includes an outer lever, an elastic member, and a retaining member. An activation state of the parking lock device is switched by the outer lever. One end of the elastic member is mounted on the outer lever. The retaining member has the other end of the elastic member mounted thereon, and retains the outer lever in a turning position through the elastic member. The elastic member is mounted between the outer lever and the retaining member so as to exert a force in the direction of a tangent to a turning locus of the outer lever when the outer lever is not being manually operated by the driver.
