With all the benefits of the incredible Sensor Vision radar system, VMS provides the final step towards ultimate vehicle safety.
It automatically applies the brakes of the vehicle if warning signals are ignored - and is active in both forward and reverse gears.
However, to ensure auto braking only takes place when reversing, an in-built logic interface box prevents a false signal activating the brakes when driving forwards.
The radar system detects the direction of travel and will only alarm if there is an object approaching the rear of the vehicle rather than moving away.
The system monitors the speed of an approaching object. It will not alarm if the closing speed is insufficient in the outer detection zones to present immediate danger - thus minimising unnecessary alarming. Any detection within the final zone would activate the alarm immediately.
The unit incorporates a clever internal memory which logs any faults or pattern changes.
Should an incident occur, the unit can be examined to establish the detection pattern, confirm the system was functioning correctly and show if alarms had been activated but ignored by the operator.
The VMS radar system alarm function always activates upon detection of the closest object and provides accurate results.
FMCW technology - frequency modulated continuous wave - makes VMS radar different from its rivals.
In less advanced systems, larger objects which are further away can often conceal closer and smaller objects - thus increasing the likelihood of an incident occurring.
Generally, the braking pressure used is around 50 per cent of full braking pressure to avoid over-exertion of the vehicle’s braking system however ensure smooth but fast stopping.
A simple key switch disables the auto braking function if required. One example of this is if a vehicle was working in a blast area and needed to reverse away quickly to avoid the results of the blast.
However in this scenario, audible warnings would still be active.
