Abstract
A system and method for controlling condensation on the windshield of a vehicle caused by a difference in environments inside and outside of a tunnel. The system and method include a tunnel information acquisition section acquiring a dew point D or a saturated vapor density V in the tunnel; a vehicle information acquisition section acquiring a temperature Tf around an outer surface of a windshield of the vehicle or a vapor density Vf around the outer surface of the windshield of the vehicle outside the tunnel; and a control section controlling the device so as to perform a prescribed operation when the temperature Tf is equal to or less than the dew point D or when the vapor density Vf is at least the saturated vapor density V.
Claims20
A control system of a device mounted on a vehicle, comprising:
- a tunnel information acquisition section adapted to acquire a saturated vapor density V in an environment of a tunnel where the vehicle can travel;
- a vehicle information acquisition section adapted to acquire a vapor density Vf around an outer surface of a windshield of the vehicle in an environment outside the tunnel;
- a control section adapted to control the device so as to perform a prescribed operation when the vapor density Vf is at least the same as the saturated vapor density V;
- and
- an onboard temperature sensor and an onboard humidity sensor disposed around an outer surface of the windshield of the vehicle.
A control system of a device mounted on a vehicle, comprising:
- a tunnel information acquisition section adapted to acquire a dew point D in an environment in a tunnel where the vehicle can travel or acquire a saturated vapor density V in the environment in the tunnel;
- a vehicle information acquisition section adapted to acquire a temperature Tf around an outer surface of a windshield of the vehicle in an environment outside the tunnel or acquire a vapor density Vf around the outer surface of the windshield of the vehicle in the environment outside the tunnel;
- and
- a control section adapted to control the device so as to perform a prescribed operation when the temperature Tf is equal to or less than the dew point D or when the vapor density Vf is at least the same as the saturated vapor density V.
A vehicle including a control system and a control target device comprising:
- a tunnel information acquisition section adapted to acquire a dew point D in an environment in a tunnel where the vehicle can travel or acquire a saturated vapor density V in the environment in the tunnel;
- a vehicle information acquisition section adapted to acquire a temperature Tf around an outer surface of a windshield of the vehicle in an environment outside the tunnel or acquire a vapor density Vf around the outer surface of the windshield of the vehicle in the environment outside the tunnel;
- and
- a control section adapted to control the control target device so as to perform a prescribed operation when the temperature Tf is equal to or less than the dew point D or when the vapor density Vf is at least the same as the saturated vapor density V.
A control method for a device mounted on a vehicle as a control target, including:
- acquiring a dew point D in an environment in a tunnel where the vehicle can travel or a saturated vapor density V in the environment in the tunnel;
- acquiring a temperature Tf around an outer surface of a windshield of the vehicle in an environment outside the tunnel or a vapor density Vf around the outer surface of the windshield of the vehicle in the environment outside the tunnel;
- and
- controlling the device so as to perform a prescribed operation when the temperature Tf is equal to or less than the dew point D or when the vapor density Vf is at least the saturated vapor density V.
