ntt:: The presented proposal does not cover all the diversity of vehicle manufacturer implementations. An
adaptation to each application will be required. A carefully revision of your vehicle documentation is
advised.
The START/STOP signal has been implemented as a low-side transistor - this means that, when the signal is active, the
associated pin XG3-H1 is internally grounded (conducting condition). Otherwise, the pin is in high-impedance condition
(blocking condition).
Concept
•
This function is beneficial to improve the refrigeration performance during long periods of engine stops due to
vehicle START/STOP activation (eg. Traffic jam, urban distribution with high density of traffic lights etc.)
•
The Gateway Controller (GC) has a digital output (START/STOP signal) that indicates that the refrigeration unit
demands electric power from the alternator.
•
The START/STOP signal can be used to inhibit the start/stop function of the vehicle allowing to:
–
Maintain the engine running despite the vehicle engine stop conditions are met (Typically the vehicle is stopped,
gear not engaged etc.)
and/or
–
Activate the engine start. All the safety precautions have to be considered by the OEM vehicle manufacturer
(seat belt fastened, door closed, battery charged etc.).
•
Check the vehicle documentation if the vehicle is equipped with such a feature and how to integrate into it’s
circuitry.
•
The START/STOP signal is linked to the activation of the Compressor Drive Module (CDM) which is the main
consuming load. When the CDM is active the start stop is active.
•
A delay (3s) between the activation of the START/STOP signal and the activation of the Compressor Drive Module
(CDM).
N
No
otte
e:: This is to prevent simultaneously starting the vehicle engine with a load due to high current demand from the
CDM.
•
In order to prevent nuisance transients the START/STOP signal is elapsed during a time (3s) when the CDM is
disabled by the Gateway controller.
•
Dedicated paramenter SSRED and SSFED are considered to adjust to the customer application.
