Abstract
A brake force control system for vehicles, especially for motor vehicles in which one or several electrical signals dependent on the wheel acceleration are compared with predetermined threshold values and in which the resultant electrical signals are utilized for the control of actuating elements such as solenoid valves in the brake circuit, whereby the electrical acceleration signals are weighted in a manner known as such and this weighting is adapted to be influenced or even discontinued when exceeding the threshold value and/or in dependence on the polarity of the acceleration signal.
Claims15
A threshold switching arrangement for use in brake force control systems and the like, characterized by an operational amplifier means having an input, an output and a feedback circuit means between said input and output including a parallel resistance-capacitance network means and further means connected with said network means for changing its operability in relation to a predetermined threshold value of the operational amplifier means, said further means including a further network connected in parallel with said network means and including a parallel connected resistance-condenser circuit series connected with a diode.
A threshold switching arrangement for use in brake force control systems and the like, characterized by an operational amplifier means having an input, an output and a feedback circuit means between said input and output including a parallel resistance-capacitance network means and further means connected with said network means for changing its operability in relation to a predetermined threshold value of the operational amplifier means, said further means including a control element operable to effectively disconnect said network means and a further network connected in parallel with said network means and including a parallel connected resistance-condenser circuit series connected with a diode.
A threshold switching arrangement for use in brake force control systems and the like, characterized by a noninverting operational amplifier means having an input, an output and a feedback circuit means between said input and output including a parallel resistance-capacitance network means formed of a resistor connected in parallel with a condenser and further means connected with said network means, said further means being responsive to the output of the operational amplifier means in relation to a predetermined threshold value for changing the operability thereof to maintain the output of the operational amplifier means at a prescribed level.
