Abstract: A route generation apparatus (13) has: a generating device (132) and a setting device (132). The generating device generates, on the basis of an evaluation score (SC2), a moving route of a movable object (1) that reaches a second position (WP_end) from a first position (WP_start) so as to avoid an interference between the movable object and an obstacle (O). The evaluation score is obtained by executing a weighting process on a distance (D_FL, D_FR, D_RL, D_RR) between the obstacle and specific portions (E_FL, E_FR, E_RL, E_RR) of the movable object on the basis of weighting coefficients (w_FL, w_FR, w_RL, w_RR). The setting device sets at least one weighting coefficient on the basis of a moving condition of the movable object during a period when the movable objects moves on the moving route.

Abstract: A parking assist apparatus (13) has: a learning device (131) configured to learn a first position (WP_start) that is a position of the vehicle when a driver starts a parking operation, a second position (WP_shift) that is a position of the vehicle when the driver changes a shift range of the vehicle and a third position (WP_end) that is a position when the driver completes the parking operation during a period when the driver performs the parking operation; and a generating device (132) configured to generate, as a target route (TR_target) along which the vehicle should travel when the vehicle is automatically parked, a traveling route that reaches the third position from the first position via the second position on the basis of a learning result.

Abstract: A parking assist apparatus (13) has: a learning device (131) for learning, when a driver performs a parking operation, a specific position (WP_shift) that is a position of the vehicle (1) when a behavior of the vehicle satisfies a predetermined condition; a setting device (132) for setting a transit position (WP_transit) in a first predetermined area (CA) including the learned specific position; and a generating device (132) for generating, as a target route (TR_target), a first traveling route that reaches a target position (WP_end) via the set transit position, the setting device sets the transit position on the basis of a first evaluation score (SC1) of the first traveling route that is determined on the basis of at least a change rate of a curvature of the first traveling route and/or a distance between the first traveling route and a first obstacle that exists around the first traveling route.

Abstract: An object is to carry out an abnormality diagnosis for a variable compression ratio mechanism without adding any special hardware configuration for estimating a compression ratio. An abnormality diagnostic device for a variable compression ratio mechanism adapted to be applied to an internal combustion engine comprises a controller configured to calculate a predetermined rotational speed difference which is a rotational speed difference, between an engine rotational speed at a predetermined crank angle before or after compression top dead center and an engine rotational speed in the vicinity of the compression top dead center for a predetermined cylinder at the time of carrying out fuel cut processing, set a reference range of the predetermined rotational speed difference, and make a diagnosis that abnormality has occurred in the variable compression ratio mechanism when the predetermined rotational speed difference is out of the reference range.
