New Energy Platform Development

Dowway Vehicle can provide customers with new energy platform solutions, including:

● Chassis system

● Three electronic system

● E&E Architecture

描述
Chassis system

Provide the whole process of chassis engineering services, including: chassis platform planning, chassis layout, system selection and design, chassis dynamic performance development, durability and lightweight performance development, chassis electronic control system development, module and platform design, chassis prototype trial, prototype test verification and debugging, supply chain development support.

platform and modular planning of Chassis system

Based on the chassis development objectives (performance, cost, function, weight, mass and other multi-dimensional objectives), the selection of chassis suspension, steering, braking and other system solutions and the overall platform planning.
