Standardizing specialty vehicle design with the smart gateway module

Smart gateway modules and Configuration app

Business objective


While consumer automobile manufacturers have the benefit of scale on their side, specialty vehicle makers must contend with a highly fragmented market. The requirements and capabilities of an ambulance differ almost entirely from those of a fire truck, a snow plow or a taxi cab. Each of them has its own external hardware that interacts with the vehicle and its controls in a unique way.


Creating the gateway modules that connect the hardware to the vehicle is a customized task that changes with each new vehicle or equipment model, increasing the cost of design and production for specialty vehicle makers. It also increases the time that it takes to bring a specialty vehicle to market as outfitters can spend up to 18 months configuring the necessary custom hardware and software.


One manufacturer came to Flex with this problem, hoping to reduce its cost of production and its time to market.


There are so many benefits to a module like this. With a high degree of flexibility, optional wireless communication functions, and a greatly decreased time to market, this system simply cannot be ignored.

Flex’s answer to the client’s problem was the Smart Gateway Module and FlexConfig app. This system replaces the traditional custom gateway module altogether. Instead of requiring a new hardware and/or software configuration for every new specialty vehicle model, Flex’s solution is a single, highly-configurable box that can be used across any new vehicle.


Historically, the vehicle manufacturer would need complex electrical engineering skills to configure a gateway module, and might even have needed to outsource the work to a third-party module manufacturer.


Thanks to the ecosystem that Flex has built around its Smart Gateway Module, the manufacturer was able to directly upgrade the software itself. It did this using the FlexConfig app that ships with the module.


FlexConfig provides a simple graphical programming interface. The manufacturer was able to cut valuable time from its production cycle by configuring the Smart Gateway Module to suit its own needs as it changed the design of the vehicle and the hardware that connected to it.




Flex was able to use its expertise in automotive design, combined with the client-centric customization capabilities, to create an optimal solution for the manufacturer’s needs. Its Connectivity Module not only allowed the dispatcher to get status updates from the vehicle and its specialty hardware in real time, but to control aspects of its operation as necessary.


“There are so many benefits to a module like this. With a high degree of flexibility, optional wireless communications functions, and a greatly decreased time to market, this system simply cannot be ignored,” says Matthias Lutz, General Manager, Stuttgart Design Center.


Thanks to Flex, the vehicle manufacturer was able to cut unnecessary complexity and cost out of its specialty hardware design, meaning that it could update its vehicle in two to four weeks, compared to a previous design cycle of eight to 18 months. It was also able to dramatically enhance the upgrade cycle for its telemetry and communications hardware from several weeks to just days.
