Interference signals suppression circuit for anti-blocking brake - has device eliminating wheel speed sensor signal amplitude dependence on speed or frequency

摘要

The circuit is intended for use in an anti-blocking control system for the brakes of a motor vehicle. The circuit is used for suppression of interference signals generated by sensor systems, esp. inductive pickups which scan the speed of rotation of one of the wheels of the motor vehicle. They generate signals proportional to the speed, and apply them for evaluation to a sequence control circuit. A device eliminating the dependence of sensor signal amplitude on speed or frequency is provided between the sensor and the sequence control circuit.
