Abstract
A vehicular heat management device includes a first heat source, a second heat source, a heater core, a first heat medium pathway, a second heat medium pathway, a heater core pathway, a switching portion, and a control unit. The first heat source is provided in the first heat medium pathway, and the second heat source is provided in the second heat medium pathway. The heater core is provided in the heater core pathway. The switching portion switches between flowing connection and flowing disconnection. The control unit performs at least one of a switching control and a second heat source control when a temperature of the heat medium of the heater core pathway is at or above a predetermined temperature. In the switching control, the switching portion connects the second heat medium pathway to the heater core pathway. In the second heat source control, the second heat source generates heat.
