Driver display information from Continental

The World Truck instrument cluster is an intelligent electronic device with latest communication interfaces. This instrument cluster was developed at Continental Automotive R&D; locations in Europe by using state of the art technologies. This is the first of its kind being developed & launched in the commercial vehicle segment in India with the contemporary features of European market.

Presently, the truck segment in India employs only Electro-mechanical gauges and does not have any intelligence built in it. The function offered by the instrument cluster of today include analogue gauges (like Speedometer for vehicle speed, Tachometer for Engine RPM, Fuel gauge, Temperature gauge, Air Pressure gauge, etc.,), warning symbols, mechanical odometer and buzzers for alarm. With this architecture, it is not possible for the driver to be aware of the exact state of the vehicle and respond proactively to avoid breakdowns.

The World Truck instrument cluster receives both digital and analog inputs via various sensors and also via communication network bus. Using this information, the instrument cluster evaluates and calculates current driving and vehicle parameters, which is displayed on the analog gauges (driven by high precision electronic stepper motors), warning symbols (illuminated by LEDs), audible warning signals and the error messages in the center display.

The instrument cluster is capable of receiving different error messages from other electronic control units in the vehicle and inform the driver by displaying them on center display. This keeps the driver informed of the state of the vehicle so that he can act accordingly. This is possible since World Truck Instrument cluster use latest communication technology called CAN (Controller Area Network).

Some of its key features are the communication network interface for other ECUs in the vehicle, fuel consumption information, display menu option in two languages (English and Hindi), clock, engine hours & error messages in center display, audible warning signals, low fuel & high temperature warning, and illumination dimming function

Human machine interface

The software for this cluster is written by using the Model Based Development System (MBDS) technology, which makes development faster. The World Truck instrument cluster also employs special software which facilitates different types of screens on the display. Using this, the driver is provided with the option of viewing different functionalities and also in different languages (currently English & Hindi language offered). It also has fuel consumption features like average mileage information, distance to empty, etc. This instrument cluster stores error information in itself so that the information can be downloaded at the service station later by service personnel using diagnostic tools. It has also the scaleable feature to meet the futuristic demands like communication interfaces with tachographs, information display for both passenger and driver, integrated telematics system, etc.
