Power generation control device for a hybrid electric vehicle

PROBLEM TO BE SOLVED: To provide a power generation control device of a hybrid electric automobile for the work capable of more reducing noise in the case of a working mode. SOLUTION: When a vehicle is in the state of running, power generation with a generator 8 is started when the residual capacity of a battery detected by a battery residual capacity detector 13 is at most 60%. When a power taking- out device 5 taking out the driving power of a motor as the power for work is in the state that working is possible, power generation with the generator 8 is started when the residual capacity of the battery is at most 35%. When the power taking-out device 5 is in the state of standby, the generator 8 is so controlled that power generation is forbidden until the residual capacity of the battery becomes 30% or less.
