DESIGN CHALLENGES
Electrohydraulic braking is based on existing ABS systems with the addition of several enhancements. The inclusion of analog
electrohydraulic valves requires closed-loop, current-controlled pulse width modulation (PWM) outputs from the electronic control unit
(ECU).
An EHB system is required to incorporate a fail-safe state in the event of a fault occurring. To correctly initiate the fail-safe state, the
system relies on its electronic components to provide a high level of operational fault coverage.
MOTOROLA SOLUTION
An EHB system requires mid-range performance MPC500 microcontrollers for system control with SMARTMOS companion chips for
functions such as load driving, sensor interfacing, voltage regulation, and system watchdog operation.
Motorola has gained experience developing many of the specific aspects required for the implementation of an EHB system. Because
of its extensive experience in the development of fail-safe microcontrollers, braking-specific modules such as the wheel speed timer,
and a software center including drivers, tools, and operating systems, Motorola has proven its ability to develop the right solutions in
collaboration with its customers.
