Abstract

A vehicle includes an air-path portion, an engine, and a rotating fan located more rearward than first and second seats. A wind pressure near the air-path portion located on a side surface of the vehicle is detected by a pressure sensor, and based on a detection result, an ECU controls a direction of rotation of the rotating fan. The rotating fan introduces/discharges air to/from an engine room via the air-path portion. If the pressure sensor detects a negative pressure, the rotating fan is controlled so as to discharge air from the engine room via the air-path portion. On the other hand, if the pressure sensor detects zero or a positive pressure, the rotating fan is controlled so as to introduce air to the engine room from the air-path portion.

First claim

What is claimed is:

1 . A vehicle including an air-path portion, the vehicle comprising:
a first seat for a driver; a second seat located next to the first seat; an engine located more rearward than the first seat and the second seat; a rotating fan located more rearward position than the first seat and the second seat to introduce/discharge air via the air-path portion to/from a region where the engine is disposed; a detector to detect a condition of the vehicle; and a controller configured or programmed to control a direction of rotation of the rotating fan based on a detection result from the detector; wherein the air-path portion is located more rearward than the first seat and the second seat and on a side surface of the vehicle.

2 . The vehicle according to claim 1 , wherein the detector detects information correlated with a wind pressure near the air-path portion as the condition of the vehicle.

3 . The vehicle according to claim 1 , wherein
the detector includes a pressure sensor to detect a wind pressure near the air-path portion; and the controller is configured or programmed to control the direction of rotation of the rotating fan based on a detection result from the pressure sensor.

4 . The vehicle according to claim 3 , wherein the controller is configured or programmed to control the rotating fan so as to discharge air from the region where the engine is disposed via the air-path portion if the pressure sensor detects a negative pressure.

5 . The vehicle according to claim 3 , wherein the controller is configured or programmed to control the rotating fan so as to introduce air to the region where the engine is disposed via the air-path portion if the pressure sensor detects zero or a positive pressure.

6 . The vehicle according to claim 3 , wherein the pressure sensor is located farther outward on the vehicle than the rotating fan.

7 . The vehicle according to claim 3 , further comprising:
a rear wheel; wherein the pressure sensor is located more forward than the rear wheel; and the vehicle further comprises a shield located between the pressure sensor and the rear wheel.

8 . The vehicle according to claim 1 , wherein an axis of rotation of the rotating fan extends in a direction toward the region where the engine is disposed.

9 . The vehicle according to claim 1 , further comprising a radiator located between the air-path portion and the engine to receive air from the rotating fan via the air-path portion.
