Patent attributes
In this steer-by-wire steering reaction force control device, a steering controller is provided with: a turning reaction force estimation unit configured to calculate an estimated value of a turning reaction force or a parameter representing vehicle behavior from a vehicle motion model; and a comparison unit configured to compare the estimated value calculated by the turning reaction force estimation unit with a value detected by a turning reaction force sensor, and configured to select either one of the estimated value and the detected value in accordance with a predetermined condition. Further, a steering reaction force generation unit is provided that is configured to use the estimated value or the detected value selected by the comparison unit for generation of a steering reaction force.
