Supply connection for anti-skid circuit - has part of circuit connected to battery via logic circuit to protect against battery drain

摘要

At least part of the anti-skid brake control circuit is connected to the battery by a special logic circuit which is activated by one of a number of control connections. These include operating the ignition switch. The anti-skid control can thus be set into a ready state without any battery drain. As soon as anti-skid control is required the circuti is powered. Other inputs to the control include wheelspeed sensors, which can be coupled via an overall control circuit. A time delay protects teh battery drain against transients and ensures the anti-skid is only activared when required. ADVANTAGE - Anti-skid protection without ignition having to be switched on, prolonged battery life.
