Various antilock braking systems, devices, and methods using sensorized brake pads are disclosed. In some embodiments, the present disclosure provides a method for improving the performance of an antilock braking (ABS) and anti-slip regulation (ASR) system of a vehicle. The method can include detecting the actual value of the coefficient of friction (e.g., between a tire and the ground), updating the coefficient of friction during braking using the braking torque data derived from at least one braking pad of each wheel, and adjusting brake force. For example, the brake force can be adjusted as a function of and/or to be approximately equal to the value of the actual tire-road friction during braking.

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.

This electric brake device includes: a brake rotor, a friction member, a friction member operator, an electric motor, and a controller which controls, by controlling the electric motor, a braking force generated as a result of contact between the friction member and the brake rotor. The electric brake device includes a vehicle speed estimator which estimates the speed of the vehicle having the electric brake device mounted thereon. The controller includes a power limiter which limits the power that drives the electric motor. When an estimated vehicle speed, which is the speed of the vehicle estimated by the vehicle speed estimator, is in a determined low-speed range, the power limiter limits the power in accordance with a condition that has been determined such that the maximum power consumption of the electric brake device decreases in accordance with decrease in the estimated vehicle speed.
