摘要： 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.

摘要： The adaptive brake application and initial skid detection system allows rapid brake application and prevents deep initial skids. Brake pressure is compared with a predetermined threshold brake pressure. Wheel velocity error signals are also generated to indicated the difference between the wheel velocity and a reference velocity signal. A pressure bias modulator integrator responsive to brake pressure signals adjusts the wheel velocity error signals to provide an anti-skid control signal. The pressure bias modulator integrator can also be initialized to the value of the measured brake pressure when the wheel velocity error signals indicate the beginning of a skid. Brake pressure difference signals are generated to indicate the difference between brake pressure and a commanded brake pressure, and an adjusted brake pressure error signal is generated in response to the brake pressure difference signals.

摘要： A brake force detecting apparatus for detecting strain in a caliper bracket. The caliper bracket has two fixed portions fixed to a wheel support and a connecting portion for connecting the fixed portions. The connecting portion of the caliper bracket is formed with a recess at a position radially outside of a line connecting the fixed portions in the radial direction of a brake disc. A sensor plate is press-fitted in the recess of the connecting portion in engaged relationship with the connecting portion so as to undergo deformation generated in the connecting portion in its tensile direction. A strain gauge is attached to the sensor plate.
