Catalyst temperature control device for hybrid vehicle

摘要

A hybrid vehicle is provided in which even if the temperature of a catalyst is decreased after a long period of travel by means of a motor, the temperature of the catalyst can be increased immediately and the exhaust of harmful materials can be suppressed. A hybrid vehicle having a normal travel mode as a travel mode in which travel is conducted while switching between motor travel and engine travel in accordance with the degree of the depression of an accelerator, comprising: a switching device being capable of switching between the normal travel mode and a specific travel mode in which travel is conducted only by means of an engine irrespective of the degree of the depression of the accelerator; an activity detector for detecting activity of a catalyst provided in the exhaust system of the engine employed in the engine travel; and a determination device for determining whether or not the catalyst is activated; wherein when the determination device determines that the catalyst is not activated, the switching device compels the switching of the travel mode to the specific travel mode engine.
