|
Hardware
In the
Loop
Test
Bench
for
Validation
of ABS
and ESC
Electronic
Control
Units
Features
-
Hydraulics
- Real physical hydraulic plant, to avoid modeling and tuning the hydraulic model
-
Linear
electro-mechanical
actuator
- Advanced driver's brake action simulation, by means of a high performance linear electro-mechanical actuator, feedback force & position controlled
-
Fault
Insertion
Unit
- Electrical faults: open and short circuit to GND or Vbatt
- CAN faults: missing message, wrong signal
- Vbatt change
-
Vehicle
modeling,
simulation
and
tuning
- Validated vehicle model in CarSim

Advantages
of a
test
bench,
respect
to
proving
ground
- Faults
insertion:
difficult
to
implement
on a
vehicle,
easy on
a test
bench
- Possibility
to
easily
monitor
all
vehicle
variables
- Possibility
to
implement
virtually
any test
(road,
vehicle,
maneuvers)
- Test automation
Repeatability
(environment,
driver
controls,
vehicle
are
controlled
precisely)
- Time /
Cost
saving
to
execute
maneuvers
