Solve Your Network Challenges With ATEC

Are you facing up to these challenges?
ATEC will take the best course of action to achieve a prompt resolution.

Vehicle CAN communication occasionally stops, making it impossible to communicate

We perform bus load reproduction with CANoe, communication waveform analysis, communication timing analysis, and other tasks to isolate the cause.

Inconsistent communication specifications between multiple ECUs

We use tools to centrally manage communication specifications, with a particular focus on checking and managing version consistency.

Design support for new communications systems for next-generation vehicles

We support new ECU development based on the latest design information, covering everything from hardware design to software aspects including protocols.

ATEC’s Automotive Network Design Solutions

Communication network manager (bus manager)

Our experienced automotive network design engineers perform CAN communication management, facilitating the exchange of various types of information between automotive ECUs.
Serving as the “command center for communication,” it supports efficient and reliable communication by managing network startup and shutdown, coordinating communication timing, monitoring communication status between ECUs, and handling errors.

Design of an automotive network relay ECU (gateway ECU)

The gateway ECU plays a crucial role in connecting different in-vehicle networks (such as CAN and LIN) and efficiently relaying data transmission between multiple automotive ECUs.
Experienced engineers efficiently and securely manage communication across the entire automotive system, acting as a bridge while maintaining the independence of each network.

Cybersecurity assessment

A process for evaluating and analyzing cybersecurity risks and vulnerabilities in automotive systems.
More specifically, by identifying potential attacks and vulnerabilities and confirming the necessity and priority of countermeasures, we support the effective planning and implementation of security measures.
This is an “evaluation process to check security” for safeguarding against cyberattacks.
