Abstract: A heater control device includes a camera sensor configured to capture an image of an outside of a vehicle through an image capturing transparent region of a window glass, and a camera heater configured to heat the image capturing transparent region. The heater control device is configured to: apply, to a correlation which is set in advance between an outside temperature, a vehicle speed, and energization electric power, and a temperature of the image capturing transparent region corresponding to the outside temperature, the vehicle speed, and the energization electric power, the outside temperature at a current time, the vehicle speed at the current time, and a target temperature equal to or higher than a dew-point temperature, to thereby determine defogging electric power so that the temperature of the image capturing transparent region is prevented from falling below the dew-point temperature.

Abstract: Provided is a heater control device including a camera sensor configured to capture an image of an outside of a vehicle through an image capturing transparent region of a window glass, a camera heater configured to heat the image capturing transparent region, and a glass heater configured to heat a specific region being a stop position region of a wiper blade. The heater control device executes heating control of energizing the glass heater to heat the specific region during a period from an operation start time of an operation switch to an operation end time of the operation switch at the earliest. The heater control device executes deicing control of energizing the camera heater in order to deice the image capturing transparent region when a deicing execution condition, which is satisfied during a period from the operation start time to the operation end time at the earliest, is satisfied.

Abstract: An information transmission system is capable of efficiently and smoothly transmitting and receiving supply information among an information storing and providing apparatus and a plurality of information receipt apparatus. The information storing and providing apparatus includes means for broadcasting at least one of category information, contract information, and time information concerning the supply information, and a plurality of information apparatuses each include means for determining whether the supply information is necessary, available, and the up-to-date, referring thereto.
