The subject of the application has a fuzzy controller which forms a pressure rate of change as a function of a wheel slip, a wheel acceleration, a locking pressure and a ratio between the actual pressure and the locking pressure. The rate of change is supplied, via an integrating unit, to an actuator of an electromechanical braking system. The locking pressure can thereby be adapted dynamically as a function of the wheel slip. Optimal antilock braking control for electromechanical braking systems is achieved through the selection of the input and output variables and the rule base.
A motor-driven feedback mechanism for a braking pedal. A pedal is linked to a shaft and a bi-directional motor capable of operating in a first and a second direction is linked to the shaft. A gearbox is driven by the bi-directional motor and the gearbox is attached to the shaft to effect rotation of the pedal. A motor controller is linked to the motor and a microprocessor capable of controlling the motor controller is linked to the motor controller. At least one sensor for measuring a parameter of the pedal and providing feedback to the microprocessor is provided.
A vehicle's operator can signal both the intended relative braking effort, and changes thereto, using a signal with a proportionately scaled and reactive display. A sensor measuring the current proportionate intensity of the intended and applied braking effort is attached to a vehicle's braking system. This sensor sends a signal to the associated external display (which may comprise multiple, separated areas). Each display area then shows that portion of its area commensurate with, or proportional to, the intensity of the intended and applied braking effort. The sensor, signal, and display(s) regularly repeat this at rapid intervals, thereby keeping the display responsive to and in accordance with the current intended and applied braking effort. In one enhancement, the outer limit of the display is activated when any braking effort is made, to enable rapid evaluation by any viewer between the relative effort applied and the potential full effort.
