Abstract: A wakefulness inducing system is capable of appropriately inducing a wakeful state in a driver even in a self-driving vehicle. A wakefulness inducing system includes a wakefulness degree sensing apparatus that senses the degree of wakefulness of a driver, a touch operation apparatus including a touch operation interface that detects contact by the operating hand of the driver, and a self-driving apparatus that controls self-driving of a vehicle. When the wakefulness degree sensing apparatus senses a reduction in the degree of wakefulness of the driver, the self-driving apparatus provides an instruction to the driver to move the operating hand to the touch operation interface, and the temperature of the operating hand is lowered in the touch operation interface upon detection of contact of the operating hand by the touch operation interface.

Abstract: A housing has a heat exchange flow passage which branches from the main exhaust gas flow passage and converges to the main exhaust gas flow passage through the heat exchanger. The valve has a valve pipe constituting the main exhaust gas flow passage in the exhaust pipe and a valve body which rotates to contact a seat part downstream of the valve pipe in an exhaust gas flow direction such that the exhaust gas flows to the heat exchange flow passage. An out port of the heat exchange flow passage which converges to the main exhaust gas flow passage is disposed upstream of a downstream side distal end of the valve pipe in the exhaust gas flow direction, and the downstream side distal end of the valve pipe in the exhaust gas flow direction is disposed upstream of a downstream side distal end of the heat exchanger in the exhaust gas flow direction.
