Smart Vehicle Harness

The next generation body function control - a revolutionary approach to the vehicle harness.

Periseo’s SmartHarness™ Electronic Control Modules (ECMs) utilised in a distributed network system (CANbus), serves as a design-time alternative to conventional wiring harnesses with fuse and relay boxes/panels in a vehicle. This drastically reduces the complexity and cost while also drastically increasing reliability and versatility. Complex high level functionality is easily configurable and reconfigurable without in depth programming experience. Configurable functionality ranges from simple switching functions, setting current trip levels and other trip behaviour through to complex decision-based functions required in modern vehicles.

These products are manufactured with care and stringently tested to meet military standards. During the equipment integration phase of each new vehicle range, designed to use our products, Periseo provide professional support to our customers in order to cut cost incurred during the integration and test phase.

Adaptations of existing products and development of new products will be considered based on the business opportunities being leveraged.

The SmartHarness™ system is suitable for use in a wide spectrum of vehicle types, ranging from military, mining and public transport vehicles to industrial and earthmoving equipment. This simplistic harness is compact, easy to install and maintain, while harness design changes could be implemented with ease. Maintenance is simplified due to the system's built-in diagnostic capability and standardised components for all vehicle types.

A simplified harness that performs complex vehicle body control functions

The SmartHarness™ intelligent harness system is a four-wire network that consists of a number of SmartHarness Electronic Control Modules (SH ECMs) installed at strategic locations in a vehicle, to provide the various body control functions. The network interconnects all SH ECMs via two communication wires (CANbus) and a power bus feed, resulting in much-simplified, light-weight and short localised wiring looms.

The SH ECM outputs are solid state switches and are connected to perform body control functions (i.e. brake light, indicator, wiper motor, headlight, etc.), keeping the wiring to each function to a minimum length. An SH ECM unit will, for instance, be configured to link the dash functions to the appropriate remotely wired SH ECMs’ outputs.

The SmartHarness™ system is adaptable to suit various applications. It is expandable by simply adding additional functions to available SH ECMs’ inputs/outputs, or by adding additional SH ECMs. A graphical user interface, in the form of a touch screen can be incorporated to monitor and control the harness and body functions, providing for real-time status feedback to the driver.
