  • Patent number: 11964618
    Abstract: In an undercover structure according to the present invention, a first cover part that is a lowermost part of an undercover has a first rear end positioned ahead of a front wheel axle. Further, a curved part with a predetermined curvature is formed at the first rear end of the first cover part in a side view. This generates a strong negative pressure in a region ahead of the front wheel axle 21. Accordingly, the flow rate of air flowing to each wheelhouse 23 decreases (the flow rate of the airflow between a road and a vehicle generated along the bottom surface of the first cover part 15a of the undercover 15 increases). This causes an attraction force that attracts the vehicle to a road surface to act on a vehicle body of the vehicle, thereby making traveling stability more excellent.

  • Patent number: 11489600
    Abstract: In the measurement device 1, a reception sensitivity test control unit 18 ends throughput measurement of a CC using a throughput measurement unit 18b in a case where an end determination unit 18c1 determines that any of a plurality of CCs has reached a measurement end condition, and calculates a total status obtained by integrating a determination result for each CC using a total status calculation unit 18c2 by performing each “PASS” or “FAIL” determination for a remaining CC. Since an output level variable setting unit 18d performs a process of setting a next output level for the CC that has not reached the measurement end condition based on the total status, a control is performed to continue a reception sensitivity test until all CCs reach a measurement end condition.
