VEHICULAR CHARGING SYSTEM

摘要

A vehicular charging system includes: a generator which has a field coil and is mounted on a vehicle; a storage battery which stores power; a storage state detection sensor which detects a charge state; and a power generation driving torque control device which calculates an actual value and a target value of power generation driving torque of the generator, and controls the generator based on the calculated target value. The power generation driving torque control device controls the generator based on a first target value of the power generation driving torque when a running state of the vehicle moves into a deceleration mode, and decreases the power generation driving torque to control the generator based on a second target value of the power generation driving torque when a charge state of the storage battery reaches a reference value, the second target value being smaller than the first target value.

1. A vehicular charging system comprising:
a generator which has a field coil and is mounted on a vehicle; a storage battery which stores power generated by said generator; a storage state detection sensor which detects a charge state of said storage battery; and a power generation driving torque control device which calculates an actual value of power generation driving torque of said generator from a duty factor with respect to said field coil, calculates a target value of the power generation driving torque of said generator from a running state of said vehicle, and controls said generator based on the calculated target value of the power generation driving torque, wherein said power generation driving torque control device controls said generator based on a first target value of the power generation driving torque when the running state of said vehicle moves into a deceleration mode, and decreases the power generation driving torque to control said generator based on a second target value of the power generation driving torque when the charge state of said storage battery reaches a reference value, the second target value being smaller than the first target value.
