Electrohydraulic braking (EHB) systems allow electronic control of vehicle braking while retaining a reduced hydraulic system. The key benefits include the reuse of hydraulic system technology, simplified calibration through software updates, improved connectivity with other systems, and the presence of an ABS without feedback from the pedal.
The document outlines the advantages of using Freescale's electrohydraulic braking (EHB) technology, which allows electronic control of vehicle braking while retaining a reduced hydraulic system. It highlights features such as software-updatable calibration, improved connectivity with emerging systems like adaptive cruise control, and the removal of large vacuum servos for flexible installation.
The system is designed to allow electronic control of vehicle braking while retaining a reduced hydraulic system that functions as a reserve in the event of a failure.
In normal operation, the controller activates the brakes of the wheel through an electric motor driven hydraulic pump.
When the controller goes into a fail-safe mode, the backup valve is opened to allow the brakes to be controlled through a conventional hydraulic circuit.
