Abstract

The air-conditioning control device is configured to control an air conditioner for a vehicle having a radiant heater and to output a cancel signal that allows an engine, which has been stopped in response to an idling stop control, to restart. The radiant heater is configured to generate radiant heat to heat an occupant in a compartment of the vehicle. The air conditioner is configured to heat an interior of the compartment using engine cooling water. The air-conditioning control device stops the engine in response to the idling stop control. The air-conditioning control device outputs a cancel signal allowing the engine to restart following the engine having been stopped such that an idling stop time is longer when the radiant heater is operated than when the radiant heater is not operated.

First claim

The invention claimed is:

1. A vehicle control system comprising:
an air conditioner that is configured to heat an inside of a vehicle compartment using engine cooling water from an engine;
a radiant heater for heating an occupant, the radiant heater being configured to generate radiant heat by increasing a temperature of a surface of the radiant heater when energized; and
an idling stop controller for stopping the engine in response to an idling stop control, the idling stop controller configured to output a cancel signal allowing the engine to restart following the engine having been stopped in response to the idling stop control such that an idling stop time is longer when the radiant heater is operated than when the radiant heater is not operated.

2. The vehicle control system of claim 1 , wherein
the radiant heater is positioned to heat an area including at least a part of an area heated by air discharged from the air conditioner toward a lower leg of the occupant.
