We Design Instrument Clusters
Two types of instrument clusters are available in the market: Point to Point (PTP) type and Multiplex (MUX) type.
In PTP types, data is delivered to inputs by wiring harness and sensors, which include fuel information, speed information, etc., and the analysis is done in the cluster.
In MUX types, information is delivered through the CAN network (high speed or low speed CAN).
The working voltage range is 8 to 18 volts, and standby current is less than 3mA to save the battery voltage level of the vehicle.
The product operating temperature range is between -40 to +85 degrees Celsius.
Mechanical
As Instrument Cluster is a visible product, the molding and injection process requires complicated techniques to ensure the best quality. The lighting of indicators needs different simulations to implement the best LED illumination and lighting design.
Electronic
All electronic circuit designs are based on ESD (Electrostatic Discharge 25kV) and all products are EMC (Electromagnetic Compatibility) proof.
Software
As the instrument cluster provides critical data to the driver, it requires the best reliable performance in the vehicle, and its software needs an operating system. Specific standards for software development should be taken into account. Our first instrument cluster was developed in 2009 for KIA Pride (SAIPA Company), and other sophisticated products came after it.
Validation
After producing the first samples, all laboratory tests for hardware validation and also validation on the vehicle would be arranged.
Pre-launch
After the validation phase, all necessary testers, fixtures, and equipment will be produced, and a pre-launch will be arranged.
Mass Production
Mass production is the final stage of any project, and we employ the IATF standard and V-cycle APQP method as our guideline for development. Product improvement is tracked after mass production based on IATF standards.
How We Design
- Collect input data and customer requirements.
- Understand the desired features, functionalities, and capabilities of the vehicle.
- Consider performance and user experience aspects.
- Create a block diagram for the instrument cluster.
- Define the layout, visual elements, and information to be displayed.
- Consider required parameters such as readability, aesthetics, and user interaction.
- Develop the hardware components required for the vehicle.
- Consider sensors, actuators, displays, and communication interfaces.
- Simulate different scenarios using hardware simulation tools.
- Connect the instrument cluster hardware to other vehicle systems.
- Ensure proper communication and compatibility.
- Validate input/output interactions.
- Design the software based on requirements.
- Implement required features such as speedometer, fuel gauge, warning lights, etc.
- Consider real-time processing, fault tolerance, and user interfaces.
- Develop a validation plan to verify the functionality of the instrument cluster.
- Test under various conditions (temperature, vibration, etc.).
- Ensure compliance with safety standards.
- Gather all necessary information for mass production.
- Design testers, fixtures, and assembly line processes for the production line.
- Optimize for cost, efficiency, and quality.
- Start the process of mass production.
- Assemble and integrate the final product into the vehicle.
- Conduct final testing and quality assurance processes.
