EonMotors - EonMotors

The Vehicle Control Unit (VCU), the “brain” of new - energy vehicles, is the core control part. As the center of the vehicle control system, it manages vehicle control based on driver inputs, speed, motor RPM, SOC, coolant temp, etc. Developing a high - performance, low - cost VCU is crucial, but its development process has challenges. A great VCU control algorithm will be a key edge for companies.

EonMotors uses Model - Based Design for control algorithm software, following the “V” process and ISO standards. We offer an integrated VCU D2P solution for EVs. It covers requirements analysis, control design, safety, networking, prototyping, testing, calibration, and industrialization, solving VCU dev challenges.

Hardware development of automotive Vehicle Control Units (VCUs) faces multiple challenges. It involves complex function integration and coordination of multiple systems. High real-time response is required. VCUs must remain reliable and stable in harsh environments and meet EMC standards. Cost control is necessary while adapting to limited space. Scalability, compatibility, and compliance with functional safety standards are also needed to ensure driving safety.

The rapid prototype development platform streamlines the controller's journey from prototype to mass production. The hardware platform offers ample interfaces, modular firmware, and a strategy library. Engineers simply configure interfaces and variables per system needs. Once verified and calibrated on the dev version, the finalized code can be directly deployed to production - ready controllers, bridging R&D and manufacturing cost - effectively, cutting lead times and expenses. We offer a range of controller hardware with 64, 121, 154 pins, etc., for customers to use on vehicles.

New energy vehicles are booming. The Vehicle Control Unit (VCU), a key part like the car's "brain", controls and optimizes based on multiple parameters. Unreliable VCU software impacts vehicle functions and safety. HiL testing, crucial in the V - shaped process, boosts reliability, being comprehensive, safe, efficient, and cost - effective.

The VCU HiL test bench provides these key functions:

- Simulate hardware input signals (AI, DI, PWM IN, resistance) and capture output signals (DO, AO, PWM OUT). - Simulate VCU CAN - bus signals and support CAN communication testing. - Fully verify VCU vehicle control strategies and support fault - diagnosis testing. - Conduct standard (e.g., NEDC) and custom driving cycle tests.
