VEHICLE AND METHOD FOR CONTROLLING THE SAME
First Claim
1. A vehicle comprising:
- an internal combustion engine capable of being intermittently stopped after said internal combustion engine is started;
a pump for circulating a cooling medium for cooling said internal combustion engine; and
a control device for controlling said internal combustion engine,when said cooling medium has low temperature, said control device controlling said pump to limit a flow rate of said cooling medium to be smaller than when said cooling medium has high temperature,when said flow rate is limited, said control device relaxing a condition applied to permit intermittently stopping said internal combustion engine, as compared with when said flow rate is not limited.

Abstract
A vehicle includes an engine capable of being intermittently stopped after it is started; a water pump for circulating cooling water, and an ECU. When the cooling water has low temperature the ECU controls the water pump to limit the flow rate of the cooling water to be smaller than when the cooling water has high temperature. When the cooling water has a limited flow rate the ECU sets lower a threshold value of the cooling water'"'"'s temperature for permitting intermittently stopping the engine than when the cooling water does not have a limited flow rate. When the cooling water has a limited flow rate the engine can nonetheless be intermittently stopped at an appropriate time.

8. A method for controlling a vehicle including an internal combustion engine capable of being intermittently stopped after said internal combustion engine is started, a pump for circulating a cooling medium for cooling said internal combustion engine, and a control device for controlling said internal combustion engine, the method comprising the steps of:
-
controlling said pump to limit a flow rate of said cooling medium when said cooling medium has low temperature to be smaller than when said cooling medium has high temperature; and relaxing a condition applied to permit intermittently stopping said internal combustion engine when said flow rate is limited, as compared with when said flow rate is not limited.
