A vehicle thermal energy control system that is able to achieve improved heat management in the entirety of a vehicle is provided. A thermal energy control system is provided in a vehicle and includes heat sources and a heat amount distributor configured to assign a demanded heat amount calculated from heat demands generated in the entirety of the vehicle, to each heat source on the basis of a suppliable heat amount of each heat source.

Vehicle thermal energy control system

An estimated temperature range is calculated by adding a plus-side temperature width to the temperature detected by a temperature sensor within the cabin of a vehicle and subtracting a minus-side temperature width therefrom, and is displayed on the display of a mobile terminal as a temperature state of the cabin. When cooling is performed, the plus-side temperature width is made greater than the minus-side temperature width. Also, the plus-side temperature width is narrowed with elapse of time from the start of pre-air-conditioning. With this operation, the temperature state of the vehicle cabin from the start of the pre-air-conditioning can be properly communicated to a vehicle user.
