Steer-by-Wire

Dowway Steer-by-Wire System is a fully electronic control solution without a mechanical steering column, replacing traditional mechanical connections with electrical signals to achieve decoupling between the steering wheel and steering wheels. It features millisecond-level response, variable steering ratio, and multiple safety redundancies, meeting the highest ASIL-D safety level and perfectly compatible with L2-L4 autonomous driving.

Core Advantages:

1, Elimination of steering column significantly enhances collision safety.
2, Lightweight and agile at low speeds, stable and precise at high speeds.
3, Supports steering wheel folding and stowage, expanding cabin space design possibilities.
4, Dual ECU + dual power supply redundancy enables fail-safe operation with safe degradation in case of failure.

Suspension-By-Wire

Enabling millisecond-level adjustment of suspension damping and height to balance handling stability and ride comfort

Vehicle Motion Control

VMC Chassis Domain Controller serves as the core control brain of the intelligent X-by-Wire chassis, leveraging a safety, real-time platform

EMB

Using in-wheel motors to directly drive brake calipers, it achieves fully electronic control of the braking system

Core Advantages:

1, Reduced body roll improved comfort.
2, Adjustable height to adapt to different road.
3, Integrate steering & braking to entire domain
4, Suit for on-road and off-road vehicles.

Core Advantages:

1, Chassis control with faster response precision.
2, Meets ASIL-D safety level with redundancy.
3, Eliminates distributed controllers, simplifyed.
4, Compatible with intelligent driving systems.

Core Advantages:

1, Response speed far exceeds traditional brake.
2, Elimination of brake fluid and hydraulic lines.
3, Deep integration with regenerative braking.
4, Supports intelligent driving, ABS/ESP,parking
