PROBLEM TO BE SOLVED: To improve the performance of a vehicle regenerative braking device that regenerates the inertial energy of a vehicle with a compressor and a genera tor when braking is applied. SOLUTION: In the vehicle regenerative braking device that controls the collection of the inertial energy of the vehicle by driving the compressor 21 of a refrigerating cycle device for air conditioning when braking is applied, a coolant storage device 26 is connected parallel to an evaporator between the outlet of the expansion valve of the refrigerating cycle device and the inlet of the compressor. When braking is applied, the driving power of the compressor 21 is increased, and an electromagnetic valve 27 is opened to prevent the excessive cooling of the evaporator 25 by increasing the flow rate of low-tension coolant to the coolant storage device 26. |
