An in-vehicle fanless computer is an industrial edge-computer designed to sustain the rigors of vehicular environments while monitoring, analyzing, and processing data from various sensors and devices required for Intelligent Transportation System (ITS) applications. These sensors transmit a continuous flow of information such as fuel temperature, engine speed, air flow, and more through an underlying CANbus network, providing vital analytics for fleet management. With added GPS and wireless data capabilities, in-vehicle computers are able to integrate IoT devices for advanced telematics and machine to machine communication. The in-vehicle computer utilizes a compact industrial product design with built-in power ignition management that controls power distribution for continuous operational stability. Taking advantage of an aluminum/steel chassis provides the in-vehicle computer with added protection and a longer service life that cuts down on maintenance costs. Its rugged fanless design offers high vibration/shock ratings and wide temperature variability for extreme operating conditions.
Power ignition Control
A fundamental design feature for in-vehicle computers that link the power supply to the engine ignition system and allows users to control the on/off delay time setting to ensure proper startup and prevent risk of losing data from sudden shut downs.
Power ProtectionUndervoltage and Overvoltage Protection
The over-voltage protection feature redirects electrical output when voltage exceeds a specific threshold to prevent circuit malfunctions or damage to electrical components. Under-voltage caused by fluctuating battery voltage or degradation can be automatically detected to safely shut down operations and protect data integrity.Reverse Polarity Protection
Reverse polarity protection is necessary in the case of incorrect battery installation or during an improper jump start to protect the in-vehicle computer from an electrical current surge.Overcurrent Protection
An overcurrent protection device that corrects an overcurrent caused by an overload, short circuit, or ground fault to safeguard electronic equipment that would otherwise overheat and destroy electronic circuits.
Rugged, Fanless, and Wide Temperature Design
Vibrations are one of the most common causes for computer system failures. Heavy oscillation can potentially knock a cable loose or damage sensitive electronic components, which is why Premio features a cableless and fanless solid state design to improve rigidity. Every Premio in-vehicle computer is validated and tested to sustain 50G shock and 5Grms vibration. Wide operating temperature ranging from -25C to 70C also ensures that the unit can run continuously 24/7 under any adverse condition.
In-Vehicle CAN Bus Protocol
The CAN bus is a message-based protocol that connects individual systems, sensors, and controllers within a network to enable smooth flow of communication. The CAN, controller network area, acts as a central nervous system connecting all parts of the body whereas the bus is the communication system that allows for data transfer between these individual components. This minimizes the workload on the controlling computer to allow for efficient data transfer and communication in a system disconnected from a central network hosting device.

In-vehicle computers are typically mounted on any open flat surface available in the vehicle. Due to the fanless and cableless design of the system, the orientation of the unit doesn’t matter. Depending on the vehicle’s cable connections, the unit can be mounted either vertically or horizontally to accommodate the vehicle’s cable layout. Some popular mounting locations for in-vehicle fanless computers can include both in the interior or exterior of the car and varies from each vehicle design to manage its sensors. The most popular mounting options for the car’s computer is under the hood or in the base of the trunk, in the passenger footwell, or even under the passage side seat.
E-Mark is an European mark required for all vehicles and electronic subassemblies. Products that are E-mark certified indicate they comply with local European laws and regulations for in-vehicle usage. Any electrical equipment that are designed to be fitted and operational in a vehicle are considered an Electronic Sub Assembly (ESA). These ESA must adhere to the EMC requirements for local automotive directives. The ACO series is E-mark certified ensuring all the external ports are EMC certified for in-vehicle usage and the system as whole will not cause any type of electromagnetic interference (EMI) with other ESA installed. The value of the E-mark certification may also extend beyond the European community, as many other countries outside of Europe also based their regulatory requirements on E-mark; some countries will also accept E-mark certification as proof of regulatory compliance.
EN50155 is an international certification covering computers used on rolling stock for railway applications. Designing computers for railway poses some unique challenges due to the harsh and constant vibrational environment with limited space availability. In order to address safety and reliability concerns for systems used on railways, the four critical elements of EN50155 are:
- Shock and vibration rating: For systems installed on trains, protection against shock and vibration is critical due to the constant vibrational stress generated by a moving train. EN50155 certification ensures all systems can meet or exceed this requirement.
- Electromagnetic compatibility rating: Due to the limited space availability on a train, multiple units may be installed that are very close to each other. In order to prevent electromagnetic interference (EMI) between all the system, the unit must be certified to meet strict EMC criteria. All external ports are tested and ensure they are EMC compliant.
- Operational temperature rating: The system must be operational over a wide range of temperature from -40C to 70C. This is to prevent the unit from overheating when installed into a confined space with limited or restricted ambient airflow.
- Power protection rating: Electronic equipment installed on railways must be protected against unexpected power surge or spike, directly or indirectly. With Over Current and Over Voltage Protection circuit, the system is well protected against sudden power spikes.

CAN Bus Transportation Protocol
CAN bus is an underlying nervous system of a vehicle that enables Electronic Control Units (ECU) to exchange data between each other with up to 6000 CAN messages per second. Each individual ECU controls a vital function of a vehicle which in turn generates valuable engine performance information over the control area network. Premio in-vehicle computers are able to directly tap into this data source for processing and provide real-time analytics for fleet management and IoT applications.
Industrial Reliability & Compact Design for in-vehicle deployment
RAID 5 for storage protection
By utilizing RAID 5, we can greatly reduce storage failures by splitting the data into multiple storage devices; so in the event of a single device failure, all the data will still be protected and intact and the system will continue to operate normally.
By eliminating fans as a mechanical point of failure, system reliability is much higher. In order to accommodate a fanless design, the material of the chassis is made of extruded aluminum with heavy duty metal. This ensure the entire unit is properly cooled with thermal dissipation, which will allow the unit to function reliability in a wide range temperature rating of -40C to 70C.
One of the most common point of failure is connection between cable, ranging from defective cable to improper latching between two points. With a cableless design, we can eliminate this possible failure mode. In addition, this will improve serviceability inside the unit as there is no cable clutter present.
Since there is limited space in a vehicle or railway, the system must be as compact as possible. The ACO with 16 PoE ports measures only 240 (W) x 261 (D) x 100 (H) mm. This small form factor allows the unit to control up to 16 security cameras in a bus or train application.
