Brake Overuse Alert - The Bendix ® Wingman ® Advanced ™ system
provides a warning when the system is intervening and using
the foundation brakes excessively. Overuse of the foundation
brakes can lead to the brakes overheating and a potential loss of
braking performance caused by brake fade.
Using cruise control
on downhill runs will cause this alert to be activated.
Approach grades as you would normally, with the appropriate
gear selected and at a safe speed.
Cruise control should NOT be used on downhill grades.
When the system detects brake overuse, depending on the vehicle
manufacturer, a text message will be displayed on the dashboard
and an audible alert will be activated. The driver should intervene
immediately.
• Once the brake overuse alert is activated, certain driver interventions
that cancel cruise control–such as stepping on the brake pedal or
switching off cruise–will discontinue the alert. Following an overuse
alert, the driver should not reset cruise control for at least 20 minutes.
This gives the brakes time to cool down. If the driver chooses to
reset cruise control during that 20 minute period, Wingman Advanced
interventions will be limited to de-throttling and engine retarder only.
The system will automatically disable all Wingman Advanced system
foundation brake applications for at least 20 minutes.
• If the system does not detect a driver intervention within 15 seconds
after the brake overuse alert sounds, it will shut itself off and set a
Diagnostic Trouble Code (DTC). The driver will continue to receive
alerts, but ALL Wingman Advanced interventions (de-throttling,
engine retarder or brake applications) will be disabled until the next
ignition cycle.
Note: In all cases, the driver still has the ability to apply the foundation
brakes if necessary. The driver should take care since overheated
brakes may reduce the vehicle’s braking capability.
