FAULT-TOLERANT ELECTRONIC BRAKING SYSTEM

摘要

A fault tolerant electronic braking system for a vehicle has a brake pedal (50) arranged to provide an electronic signal in response to operation thereof. A number of braking nodes (10, 20, 30, 40) are coupled to the brake pedal, each node being arranged to control a brake actuator (15, 25, 35, 45). Each brake node (10, 20, 30, 40) has a controller arranged for processing the first signal to provide a second signal for controlling the brake actuator (15, 25, 35, 45), and for providing third signals for transmission to the other control means. The third signals are the expected second signal results of the other controllers. Each controller is arranged to compare the second signal with the third signals received from the other controllers such that errors detected between the second and third signals indicate faults in the controllers.
