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.

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.
