Title: Brake control system for vehicles
IPC: B60T8/173
Filed: 1971-09-03
Abstract: 1363505 Braking control devices DAIMLERBENZ AG 3 Sept 1971 [5 Sept 1970] 41238/71 Heading F2F  A vehicle braking force control device compares one or more acceleration-dependent electrical signals with a predetermined threshold value to provide electrical signals to brake operating members, the electrical acceleration signals being integrated and then compared with the threshold value, the maximum value of the integrated signals being limited to a predetermined value above the threshold, the integration being controlled or cut-out if the threshold is exceeded and/or in dependence of the polarity of the acceleration signal. Fig. 1 shows an amplifier with associated resistors 13, 14 to produce a predetermined amplification, and a capacitor 15 in parallel to damp out spurious signals, the output signal, when attaining a value greater than the threshold value, triggering a threshold switch to actuate the operating members. However, the lag on signal reduction caused by the capacitor 15 when the input is reduced, is undesirable, and a Zener diode 16 is inserted in parallel to limit the maximum output signal to just above the threshold, so that upon input signal reduction, the capacitor time-lag is negligible. Another way of retaining the capacitor time-lag for input signal increase but obviating the lag for input decrease, is to replace the diode 16 by a transistor 26, Fig. 3, controlled by a feed-back from the threshold switch 28, so that when the output signal is above the threshold, the transistor "blocks-off" the capacitor 15 to remove its effects, but still allowing the initial time-lag below the threshold value. Another resistorcapacitor combination can be in parallel with the amplifier, with an associated diode to be actuated by a reverse polarity signal so that the amplifier operates for acceleration as well as deceleration, in this situation, two opposed Zener diodes are in parallel with the amplifier to limit either signal to just above the threshold value.
