A parking assistance device according to the present disclosure performs automatic traveling of a vehicle based on teacher traveling by a user, and includes a memory and a processor coupled to the memory. The processor is configured to: cause the memory to store information about a travel path in the teacher traveling; correct the travel path in order that a position of a target position of the automatic traveling in a vehicle width direction is closer to a structure defining a parking area configured to park the vehicle and a path to the target position having a curvature smaller than a threshold is kept longer, according to a relative positional relationship between the structure and a start position of the automatic traveling on the travel path; and control the vehicle based on the corrected travel path.

Parking assistance device and parking assistance method

A parking support apparatus includes a storage that stores a manual parking path, and a processor that sets a safety region where the vehicle can pass. The processor causes the vehicle to perform automatic driving based on the generated automatic parking path, and the processor generates a parking path configured for driving within a range of the performance of the electric power steering and for the vehicle to pass inside the safety region.

Parking support apparatus and parking support method

A driving assistance device includes a processor connected to a memory. In a teaching traveling mode, the processor stores, in the memory, a teaching traveling path obtained by a vehicle traveling from a current position to a start position designated by a user, and generates teaching data related to a teaching path obtained by reversing the teaching traveling path from an end point toward a start point. The processor causes the vehicle to travel along the teaching path in an automated traveling mode. The processor generates, in the teaching traveling mode, a recommended path in which a turning radius of a stroke of forward travel is larger than a turning radius of a stroke of backward travel in a range from the current position to the start position. The processor outputs, in the teaching traveling mode, display information for displaying a display screen including the recommended path.

Driving assistance device and driving assistance method

A parking support apparatus includes an instruction detection section that detects the occupant's parking instruction based on an operation of the occupant of the vehicle or a history of a motion of the vehicle, and a vehicle control section that performs the automatic parking of the vehicle. When the history indicates that the vehicle has stopped after steering and turning from a straight movement, and that the occupant has performed a predetermined parking instruction operation, the instruction detection section determines that the parking instruction is detected.

Radar apparatus and radar state estimation method

Cracking and flying around of permanent magnets in a permanent magnet embedded-type rotating electric machine is prevented. Thermally hardening FRP is used as a reinforcement sheet, and the reinforcement sheet is wrapped around the periphery of a permanent magnet and caused to adhere to the surface of the permanent magnet by being thermally hardened. Subsequently, the permanent magnet to which the reinforcement sheet is adhering is embedded in magnet embedding holes of the rotor. The surface of the reinforcement sheet after thermal hardening is in a state of not being attached to the inner wall surface of the magnet embedding holes. Consequently, no stress caused by the difference between the linear expansion coefficients of the rotor and permanent magnets acts on the permanent magnets when the temperature of the rotor rises, and cracking of the permanent magnets can thus be prevented.
