In normal operation SmartBrake is unobtrusive. No special actions are required to drive the vehicle. Smartbrake is installed to provide safety protection if the vehicle driver fails to perform braking actions as normal.
On entering the vehicle the normal (manual) parking brake will be on. The engine is started, the manual brake is released, and the vehicle is driven normally.
When the vehicle is brought to a halt normally the manual park brake would be engaged.
Then the engine shut down. If the manual brake is not put on before the the
driver exits the vehicle, then SmartBrake will apply its braking system.
If the driver exits the cab (ie seat vacated and door opened),
then SmartBrake will apply the brakes. The speed detection function will only allow this to occur at speeds less than the preset threshold (7kmh
approximately). Speeds higher than the threshold prevent SmartBrake from operating, thus preventing brake operation at dangerous speeds.
SmartBrake must be released by
entering the 4 digit user code on the keypad before the vehicle may be moved again after any SmartBrake operation.
SmartBrake is provided with a Maintenance,
towing and diagnostic mode. These modes are entered using the
numeric keypad provided. When the maintenance switch is operated SmartBrake is disabled, allowing servicing operations to be performed on the braking system. If the vehicle is driven with the maintenance
mode ON, an alarm will sound (beeper) when the driver sits in the seat. A flashing lamp appears on the
keypad panel. Entering the user code kills the beeper but the lamp remains flashing until the maintenance
mode is exited.
Any damage to the speed
sensor wiring (short circuit or open circuit) will prevent Smartbrake
from being activated until this condition is corrected a periodic beep
alerts the driver to the failure condition.
