Published on June 15, 2026 | By Johnny Liu (CEO at Dowway Vehicle, Former Chassis Calibration Engineer) Meet the Author As the CEO of Dowway Vehicle and a former chassis tuning engineer, I have spent years on frozen lakes and wet, low-grip test tracks. I often hear drivers simplify wet-road accidents down to a single […]

Executive Summary As the global electric vehicle (EV) sector moves away from chaotic price wars and enters a phase of mature structural consolidation, automakers are forced to rethink their supply chain architectures. On June 11, 2026, Nio’s mass-market sub-brand officially launched its updated 2026 Onvo L60 (新乐道L60), priced from 192,800 RMB (and as low as

By Johnny Liu, CEO at Dowway Vehicle Quick Takeaway Hazard Analysis and Risk Assessment (HARA) is the starting point of the ISO 26262-3 Concept Phase. It spots hazards caused by system failures and rates their risk using three metrics: Severity (S), Exposure (E), and Controllability (C). These scores combine to give you an Automotive Safety

By Johnny Liu, CEO at Dowway Vehicle Published on June 12, 2026 Quick Summary Here is a quick lookup of our key simulation settings and findings: Bearings: Simple Parts, Huge Risks Bearings are simple but highly critical parts of rotating machinery. Almost any machine with rotating parts needs bearings, including electric motors, high-speed machine spindles,

Weight Reduction: A Real-World Automotive View With electric vehicles growing fast and performance needs rising, making parts lighter is no longer optional. It is a must. At Dowway Vehicle, we push our engineering teams to strip weight from chassis parts without losing stiffness or lowering safety factors. One of the best ways to do this

Introduction: Removing the Hydraulic Safety Net In the current era of electric vehicles and automated driving, the Electro-Mechanical Brake (EMB) is widely seen as the ultimate execution unit

1. Executive Summary / TL;DR Modern drive-by-wire chassis control demands a clean balance between low-speed agility (such as tight urban maneuvers) and high-speed stability (such as highway lane changes). While Four-Wheel Steering (4WS) systems offer the theoretical capability to satisfy both requirements by switching between counter-phase (opposite steering) and same-phase (identical steering) modes, traditional control

Technical Summary What is the stability envelope ($S_c$) of a 4WS vehicle? The stability envelope$S_c$is a closed region in the Sideslip Angle ($\beta$) vs. Yaw Rate ($r$) plane. It is bounded by six limits: two yaw rate bounds ($L_1, L_2$) defined by peak road adhesion, and four sideslip angle bounds ($L_3, L_4, L_5, L_6$) calculated
