Abstract:
Provided is an electric brake device of which braking control accuracy is improved as a result of hysteresis in a load sensor being appropriately compensated for. The electric brake device includes: a direct load estimator configured to estimate a brake pressing force, using an output of the load sensor; an indirect load estimator configured to estimate a brake pressing force without using the output of the load sensor; and a hysteresis interpolator. When switching is performed between pressure increase and pressure decrease which causes hysteresis in the load sensor, the hysteresis interpolator performs control by use of the load estimated by the indirect load estimator without using the load sensor, in a predetermined range after the switching has been performed.
