<P>PROBLEM TO BE SOLVED: To prevent the deterioration of drivability caused by a change of power generation torque while efficiently charging an electrical energy storage device at regenerative power generation. <P>SOLUTION: A vehicle power generation control apparatus includes a normal power generation control means which controls the power generation of a generator 10 so that an estimated charging rate of the electrical energy storage device reaches a target charging rate when the estimated charging rate of the electrical energy storage device 12 is lower than the target charging rate, and a regenerative power generation means which controls the power generation of the generator during a vehicle is decelerated in speed and the fuel supply of an internal combustion engine is stopped. The power generation control device also includes a regeneration charging amount prediction means which predicts a charging amount at the regenerative power generation at the speed reduction according to a vehicle speed, and lowers the target charging rate of the electrical energy storage device 12 accompanied by an increase of the regeneration prediction charging amount which is obtained by the regeneration charging amount prediction means. The regenerative power generation control means limits a power generation amount in a direction in which the amount is reduced so that a difference of torque necessary for the power generation depending on the presence and absence of the power generation to the electrical energy storage device in the generator may be fallen within a prescribed torque difference. <P>COPYRIGHT: (C)2012,JPO&INPIT |
