Abstract
Official abstract text for this publication.
A vehicle traveling control method includes starting, when a predetermined condition is satisfied, inertial traveling during which a vehicle travels while stopping fuel supply to an engine of the vehicle, measuring, from a start of the inertial traveling, a temperature decrease amount occurring in a heat exchanger for heating a cabin of the vehicle with heat generated by the engine, and stopping the inertial traveling when the temperature decrease amount is greater than a threshold.
First claim
Opening claim text (preview).
The invention claimed is: 1. A vehicle traveling control method comprising: starting, when a predetermined condition is satisfied, inertial traveling during which a vehicle travels while stopping fuel supply to an engine of the vehicle; measuring, from a start of the inertial traveling, a temperature decrease amount occurring in a heat exchanger for heating a cabin of the vehicle with heat generated by the engine; and stopping the inertial traveling when the temperature decrease amount is greater than a threshold. 2. The vehicle traveling control method according to claim 1 , wherein the threshold is changed according to at least one of a decrease rate of temperature of the heat exchanger and a cumulative number of stops of the engine. 3. The vehicle traveling control method according to claim 1 , wherein the temperature decrease amount is measured based on both an air flow rate of a blower sucking air into a case for housing the heat exchanger, and a temperature of the air sucked into the case by the blower. 4. The vehicle traveling control method according to claim 3 , wherein the threshold is changed according to the air flow rate of the blower. 5. A vehicle traveling control device including: a sensor that measures a temperature decrease occurring in a heat exchanger for heating a cabin of a vehicle with heat generated by an engine; and a controller programmed to stop inertial traveling during which the vehicle travels while stopping fuel supply to the engine, when the temperature decrease amount occurring in the heat exchanger from start of the inertial traveling is larger than a threshold.
