ELECTRIC POWER STEERING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide an electric power steering device capable of improving action reliability without increasing the weight and volume of a vehicle-mounted battery.

SOLUTION: A battery voltage estimation value at the time of consuming a maximum power of an electric power steering device 3 is estimated from a voltage and a current of a battery 1. When the battery voltage estimation value at the time of consuming the maximum power is lower than a minimum action guarantee voltage of the electric power steering device 3, the consumed power of electric loads A and B connected with the battery 1 is commanded to be reduced to a range where at least the battery voltage estimation value at the time of consuming the maximum power exceeds the minimum action guarantee voltage.
