Abstract: A map generation device according to one embodiment includes a reception unit that receives probe data transmitted from at least one vehicle and indicating a feature detected in vehicle surroundings by an environment monitoring sensor incorporated in the vehicle, and the device creates or updates map data based on the probe data received by the reception unit. The map generation device includes: a characteristic determination unit that determines whether the probe data includes sufficient characteristic information usable for alignment with other probe data or map data; and a combining unit that joins a target probe data set including an insufficient amount of characteristic information to the probe data previous or subsequent to the target probe data set in consecutive probe data sets acquired from the same travel of the same vehicle.

Abstract: An air conditioner for a vehicle includes a cooling water circuit and a heater. The cooling water circuit allows a cooling water to circulate between an engine and a heater core in a heating operation. The engine is a power source of the vehicle. The heater core is configured to heat air using a heat of the cooling water. The heater is located downstream of the engine and upstream of the heater core in the cooling water circuit and is configured to heat the cooling water.

Abstract: A map generation system provides to: acquire an image of the vehicle's environment from the imaging device; analyze the image to calculate the position of a feature on the road; upload map information including the position of the feature to a server; and statistically determines the coordinates of individual features in the uploaded map information. The features include a reference mark whose absolute coordinates are determined. The coordinates of the features other than the reference mark are corrected so as to match the observation coordinates of the reference mark corresponding to the absolute coordinates of the reference mark.

Abstract: An air conditioner for a vehicle including an engine, which serves as a power source and is configured to allow a cooling water to flow therethrough, includes a cooling water circuit, a heater, temperature sensors, and an output controller. The cooling water circuit allows the cooling water to circulate therein in a heating operation. The heater serves as a heat source, other than the engine, configured to heat the cooling water circulating in the cooling water circuit. The temperature sensors are connectable to the cooling water circuit and are configured to detect a temperature of the cooling water. The temperature sensors are positioned upstream and downstream of at least one of the engine and the heater. The output controller is configured to adjust at least an output of the heater based on the temperatures of the cooling water detected by the temperature sensors.

Abstract: An air conditioning device for a vehicle includes a door control unit that controls multiple blowing port doors or an air mix door to prevent a heat generated from a heater core from leaking out of an air conditioning case before air conditioning of a vehicle interior is determined to be started. The air conditioning device includes an air conditioning control unit that performs the air conditioning of the vehicle interior by controlling the multiple blowing port doors to open at least one of multiple blowing ports and blow out a heat in the air conditioning case as hot air to the vehicle interior from the at least one blowing port after the air conditioning in the vehicle interior is determined to be started.

Abstract: A road information learning device acquires a map extraction curve and a measurement curve for a traveling curve along which a vehicle travels, determines whether the map extraction curve and the measurement curve correspond to an identical traveling curve, and registers the measurement curve as a definitive registration curve when the map extraction curve and the measurement curve correspond to the identical traveling curve, and a predetermined definitive registration condition is satisfied.
