Abstract
In a vehicle including an EHC containing a catalyst base material and an insulator insulating the EHC from the outside, an ECU estimates a temperature of the catalyst base material and a temperature of the insulator immediately after a state of the vehicle is switched from a Ready-OFF state to a Ready-ON state, as a base material temperature for determination THcpost and an insulator temperature for determination THipost, respectively. Then, when base material temperature for determination THcpost is lower than a base material threshold temperature THcth and when insulator temperature for determination THipost is lower than an insulator threshold temperature THith, the ECU allows EHC power feed, and otherwise it does not allow but prohibits EHC power feed.
Claims6
A vehicle capable of running with motive power from at least any of a motor and an engine, comprising:
- a power storage device for storing electric power for driving said motor;
- a catalytic device configured to be able to electrically heat with electric power from said power storage device, a catalyst base material to which a catalyst purifying an exhaust from said engine is fixed;
- an insulator provided between said catalytic device and a housing accommodating said catalytic device;
- and
- a control device controlling power feed to said catalytic device,
- said control device determining allowance and prohibition of power feed to said catalytic device in accordance with a temperature of said insulator.
