Latest Patents

One of his latest patents is a parking support device. This device includes a calculation unit that calculates a speed pattern, an acceleration recognition unit that recognizes driver-requested acceleration, a parking support control unit that performs parking support control in a target parking position based on the speed pattern, and a determination unit that determines whether a host vehicle can stop in the target parking position at a set deceleration. When the driver-requested acceleration is recognized during the control and exceeds the acceleration of the speed pattern at the time of recognition, the parking support control unit accelerates the host vehicle at the driver-requested acceleration. When the determination unit determines that the host vehicle can stop in the target parking position at the set deceleration, the host vehicle is decelerated at the set deceleration and is stopped in the target parking position regardless of the driver-requested acceleration.

Another significant patent is the dual polarized flat antenna device. This high-efficiency antenna device is suited for use in a mobile unit. It features a pair of triplate antennas stacked together, where the lower antenna includes a feeding probe for horizontal polarization and the upper antenna includes a feeding probe for vertical polarization. The feeding probes have patch edges at opposing ends in the polarization direction. A coupling slot for coupling the upper and lower antennas is disposed over the patch edges in the lower antenna. In-phase magnetic current runs through the patch edges, achieving a phase match between the two slots, which raises antenna efficiency. The feeding probe is disposed at an angle and oriented in a direction corresponding to a representative value of polarization angles of the traveling area, thereby reducing polarization angle loss as a whole.
