| 摘要 |
The invention is a fail-safe circuit for an antilock braking system which includes a drive circuit connected between the output of an anti-lock control and an output connector thereof that also provides connection for the system's solenoid actuated modulating valves. An energizing relay for the solenoids is connected to receive the output from the drive circuit. Control signals for the energizing relay and solenoid actuated modulating valves are of opposite polarity such that a short circuit to either positive or ground will disable the anti-lock system and obviate false operation thereof. |
