VEHICULAR WARMUP SYSTEM

PROBLEM TO BE SOLVED: To provide a vehicular warmup system capable of effectively executing the quick warmup of an engine and rapid heating in a vehicle interior. SOLUTION: The vehicular warmup system 1 includes a heat storage device 10 having a heat storage material 20 capable of executing heat storage in a supercooling state, and a nucleating device 25 for releasing the supercooling state of the heat storage material 20, an engine 30 and a vehicular heater 44 warmed up by the heat storage device 10, an electric water pump 34 arranged in a cooling water circulation passage 31, and an ECU 50 remotely operated by an engine start key 53 outside a vehicle. The supercooling state of the heat storage material 20 is released by the nucleating device 25 before starting the engine 30 according to the remote operation by a warmup switch 53a of the engine start key 53 outside the vehicle, and the cooling water heat-exchanged with the heat storage material 20 is fed to the engine 30 and a heater core 45 of the vehicular heater 44 by the electric water pump 34 to execute the quick warmup of the engine 30 and the rapid heating in the vehicle interior.
