Engineering of the consequent kind. Market demand for electric vehicles and drive trains in all segments is steadily increasing, consequently engineered solutions are still rare though. With an engineering team combining both mechanical and electronic engineering expertise, eVision automotive is partner and service provider for those companies which strive for innovative, yet solid and functional electric vehicle and drive train solutions.

Mechanical engineering

With numerous commercial vehicles being designed and developed by eVision's mechanical engineering team, eVision can ensure an optimal integration of electric drive trains in on-road and off-road vehicles of all kinds.

electronic  engineering

Sound electronic engineering capacities, including software design and programming expertise, are essential in the development of functional and energy efficient drive train solutions for on-road and off-road vehicles.

Our core competences

Product Concept & Industrial Design

Ahead of the engineering process, the product requirements are analyzed together with the customers and/or user. A product and design concept is the result.

> Analysis of product, system or vehicle requirements from a technical and/or commercial viewpoint
> Concept and design of commercial vehicles incl. component pre-selection
> Layout and physical arrangement of components and systems into existing or newly designed chassis or vehicle structures
> Product design studies or proposals where required

Component Definition & Supplier Development

In communication with suppliers, the product and component concept is translated into detailed component definitions. A structured approach to supplier development is applied.

> Selection of proven components that fit application best; off the shelf, custom production or in-house production
> Benchmark capability based on reference products and past experiences
> Established network of suppliers
> Strategic partnerships with key component manufacturers (e.g. highly specialized battery technology)

Mechanical Engineering

Based on the selection of proper software tools and the definition of documentation structures and standards (e.g. structural BOM), the mechanical engineering process can be performed.

> Definition of structures, hierarchies, assemblies, etc.
> Creation and compilation of adjunctive 3D Models for components, peripherals and systems
> Generation of production drawings
> Preparation of documentation and guidelines for later serial manufacturing

Electronic Engineering

Component concept and functional requirements provide the basis for electric engineering.

> Development of electrical drive train systems, both high- and low-voltage
> Design of wiring diagrams and cable harnesses (incl. capability of later manufacturing)
> Conception of safe high-voltage component arrangements
> Build and assembly of test benches, proof of concept for system and high-voltage components
> Design, development and assembly of dedicated, purpose optimized battery packs


Embedded Systems Architecture & Vehicle Controls

Component concept and functional requirements provide the basis for electric engineering.

> Design model specific drive train systems based on vehicle use strategy, programming in C (embedded), compliant with MISRA and automotive safety standards
> Software design and development
> Calibration and setting of all necessary software parameters (proprietary or 3rd party systems and components)
> Hardware development (e.g. VMU – Vehicle Management Unit controllers)
> CAN bus interfaces and connectivity definition and designs, including CAN diagnostics integration
> Control and settings for all relevant functions and features, such as but not limited to traction control, torque vectoring and control, transmission control, speed limiter, creep control, deceleration control, torque vectoring, parking brakes, hill-hold, general shift strategies or behaviors
> Integration of latest battery technologies (incl. LTO), proven high-voltage – 650V - 800V – track record, capability to integrate different proprietary manufacturer BMS’ – Battery Management Systems

Prototyping and Small-series Production

The capacity to build prototypes and the possibility to set up small series production/assembly (“industrialization”) makes it possible to verify own engineering efforts.

> Prototype build and assembly
> Validation and verification of deployed systems and components, performance tests and verification by means of actual drivable chassis
> Technical convergence of concept, hardware, software and actual driver/user
> Performance optimization and fine adjustment of parameters
> Transformation from lab to real-life environment, including environmental impacts (e.g. weather & temperatures)

Homologation Support

Compliance with technical and legal standards is foreseen in the concept phase and throughout the engineering process. The organization of the homologation process can be parts of eVision’s services.

> Analysis of technical and legal requirements
> Preparation of a homologation schedule together with relevant service providers (test and certification companies or authorities)
> Execution of relevant tests with homologation authority
> Compilation of homologation documentation

Technical Support in the After-sales Phase

Engineered systems and software can be serviced and maintained.

> Remote phone or e-mail field service support
> Commissioning support and ongoing field service assistance
> Possibility for remote monitoring and support thru GSM based communication (embedded into VMU)
> On-site or remote (optional) software updates and/or performance tweaking
