A battery thermal management system (BTMS) controls battery temperature and keeps it stable across all cells. It uses air, liquid, or hybrid cooling methods, supported by […]

< Back to Vehicle Design & Engineering Automotive rendering is the process of turning 3D car models into realistic images or interactive scenes using materials, lighting, and rendering engines. It’s now a core part of how cars are designed, tested, and sold—often before a physical vehicle even exists. TL;DR Why this matters If you’ve ever

< Back to Performance Development Author: Johnny Liu, CEO at Dowway VehicleLast Updated: March 27, 2026Article Type: Cluster PagePrimary Keyword: electric motor thermal analysis Electric motor thermal analysis is the process of finding where heat comes from inside a motor, predicting how that heat moves, checking real temperatures through testing, and improving cooling so the

< Back to Performance Development EV cabin thermal systems matter because they directly affect: Without engine heat: In extreme cold, HVAC can use 20–40% of total energy. That’s why this system is now treated as a core engineering problem, not just a comfort feature. What Are the Core Components of an EV Cabin Thermal Management

< Back to Steer-by-Wire A steer-by-wire (SBW) system removes the mechanical link between the steering wheel and the wheels. Instead, it uses sensors, actuators, and redundant electronic control units (ECUs) to control steering through a closed-loop system that meets ASIL-D safety requirements. There’s a point in every SBW project where the conversation shifts. Not “how

< Back to Steer-by-Wire A rear wheel steering system (RWS) adjusts the rear wheel angle based on speed and driving conditions. At low speed, it helps the car turn tighter. At high speed, it keeps the vehicle stable. It’s now a key part of modern vehicle motion control systems. Why This Matters Now Let me

< Back to Intelligent Chassis Software Last Updated: March 24, 2026Author: Johnny Liu, CEO at Dowway Vehicle Direct Answer A Vehicle Motion Controller (VMC) is the central software system that controls steering, braking, suspension, and drive systems together. It takes driver or autonomous inputs, estimates vehicle state, and distributes commands across actuators in real time

< Back to Intelligent Chassis Software Brake-by-Wire (BBW) software development is the engineering process of converting driver braking input into electronically controlled braking force using sensors, ECU software, and actuators, replacing traditional mechanical or hydraulic transmission while ensuring real-time performance and fail-operational safety. There’s a moment during a brake-by-wire project when things feel different. You’re

< Back to Intelligent Chassis Software Active suspension control algorithms manage vehicle height, damping, and body motion in real time using sensor data and control logic. In steer-by-wire suspension systems, software directly controls how fast the system reacts, how stable the vehicle feels, and how safely it behaves under faults or extreme driving conditions. When

< Back to Steer-by-Wire Quick Answer Steer-by-wire software architecture replaces the mechanical steering column with a fully electronic system. It uses AUTOSAR-based layered software, real-time control algorithms like MPC and adaptive PID, and ASIL-D safety mechanisms to control steering through sensors, ECUs, and electric actuators while maintaining reliability through redundancy and fault-tolerant design.
