HYBRID-VEHICULAR REGENERATIVE ELECTRIC POWER VOLUME CONTROL SYSTEM, HYBRID VEHICLE, AND HYBRID-VEHICULAR REGENERATIVE ELECTRIC POWER VOLUME CONTROL METHOD

Japanese Patent JP2017094835

A

PROBLEM TO BE SOLVED: To provide a hybrid-vehicular regenerative electric power volume control system, a hybrid vehicle, and a hybrid-vehicular regenerative electric power volume control method, which are capable of increasing a regenerative electric power volume of a motor-generator and sufficiently securing a charge amount of a battery connected to the motor-generator via an inverter while the vehicle travels on a down-hill road, thus improving fuel economy.SOLUTION: In a case where a traveling spot of a hybrid vehicle is down-hill with its road inclination G equal to or more than a predetermined set inclination threshold G1, control is performed to calculate a target generative electric power volume Et, that is, a target value of a regenerative electric power volume of a motor-generator 31, by adding a correction regenerative electric power volume Ec set as a positive function of a magnitude being a down inclination G at a traveling spot to a basic regenerative electric power volume Eb that is regenerative electric power volume set on the basis of a travel state of the vehicle.SELECTED DRAWING: Figure 3
