Claims

[Scope of utility model registration request]

Steering assist force control for a power steering system that prepares multiple patterns for controlling the steering assist force according to vehicle speed, steering angle, etc., and selects them according to the output signal of the vehicle's live load detector. In the device,
A power steering device characterized by having a control function such that the larger the live load is, the larger the steering assist force is with respect to the rudder angle, and the smaller the live load is, the smaller the steering assist force is with respect to the rudder angle. Steering assist force control device.
