Title:
REGENERATIVE BRAKE DEVICE FOR VEHICLE
Document Type and Number:
Japanese Patent JP2017093154
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a regenerative brake device for a vehicle, which makes it possible for an electric heater to securely consume surplus electric power during regenerative brake, the electric heater increasing heat output gradually until steady heat output from the start thereof.SOLUTION: An air-conditioning ECU has a pre-operation part in which, if it is determined through information from a navigation device that the vehicle passes through a downhill road requiring the vehicle to brake, a heater is started with electric power other than regenerative electric power before the brake is actually applied, thereby performing pre-heat output of the heater. The pre-operation part is provided by the functions of a step group S90 and a step S45 following the step group. In addition, the air-conditioning ECU has a regenerative operation part that performs heat output of the heater with regenerative surplus power when the brake is applied. The regenerative operation part is provided by the function of step S47.SELECTED DRAWING: Figure 4
