Abstract

A fault diagnosis device for a circuit controlling electromagnetic actuators may be used in a vehicle brake system (50). It sends independent control signals to a number of actuators. These operate the actuators and enable fault detection in a multiple parallel system controller. It enables simple accurate diagnosis, e.g. in an anti-locking braking system controller, and is easily applied to conventional controllers. An analogue signal oscillator provides a fault diagnostic analogue signal to the controller. A fault diagnosis logic circuit evaluates the controller output signals and gives indication of abnormal signals.
