What Is An Intelligent Chassis?

Intelligent chassis is based on By wire technology, which replaces traditional mechanical connections with electronic signals to achieve precise control of vehicle lateral and longitudinal movements.

Its core system includes wire controlled throttle, wire controlled braking, wire controlled steering, and integrates sensor networks, high-performance controllers, and intelligent actuators to form an integrated digital control platform.

Intelligent chassis is not only an innovation of traditional mechanical structures, but also the core driving force for the intelligent transformation of automobiles.

With the maturity of technology and the coordinated development of the industry chain, it will continue to reshape safe, efficient, and sustainable travel experiences.

1、 How does an intelligent chassis work?

The working mode of intelligent chassis is very similar to our body, mainly composed of three parts working together:

1. Perception (sensors): Various sensors scattered throughout the chassis, like the "eyes" and "ears" of a car, collect real-time data on vehicle speed, steering, tire pressure, road bumps, and even perceive the surrounding environment.

2. Decision making (brain): A powerful "brain" - the electronic control unit (ECU) - analyzes massive amounts of data sent by sensors and makes instant decisions, such as "smoother suspension is needed now" or "immediate light braking to maintain stability".

3. Execution (hands and feet): After receiving instructions from the "brain", actuators (such as electric steering motors, electronic brakes, etc.) will immediately take action to accurately adjust the vehicle's state.

The process of perception decision execution repeats in an instant, ensuring that the vehicle is always in optimal driving condition.

2、 What are its outstanding advantages compared to traditional chassis?

The advantages of intelligent chassis are directly related to the personal experience of every car owner and passenger:

• Safer: It can predict risks in advance.

For example, during sharp turns, the system will actively adjust the body posture to prevent skidding;

In case of emergency, its response speed far exceeds that of humans, and it can automatically brake faster, becoming a "safety guard".

By real-time monitoring of vehicle status and environmental data through multiple sensors, the intelligent chassis can actively adjust suspension damping, brake pressure, and steering assistance. Combined with multiple systems such as electronic stability control (ESC) and anti lock braking system (ABS), it greatly improves handling stability under extreme road conditions.

Based on road conditions and driving modes, the chassis parameters are adaptively adjusted to achieve seamless switching between comfortable, sporty, and economical modes, as well as obstacle detection and automatic emergency braking functions, further enhancing active safety protection capabilities.

• More comfortable: Facing bumpy roads, the intelligent chassis can actively adjust the suspension softness and hardness, effectively filtering out vibrations, like putting on "smart air cushion shoes" for the vehicle, making the riding experience in the car smoother and quieter.

Millisecond level response capability, significantly improving steering and braking accuracy.

• More energy-efficient: By optimizing power output and efficiently recovering the energy generated during braking, the intelligent chassis can effectively improve energy utilization efficiency, help electric vehicles extend their range, and make your travel more economical and environmentally friendly.

Lightweight design and simplification of mechanical structure effectively reduce vehicle weight and energy loss.

• More intelligent: It is the cornerstone for achieving advanced driver assistance (ADAS) and autonomous driving.

The modular architecture supports the rapid integration with ADAS and auto drive system, and provides the underlying support for intelligent navigation, automatic parking and other functions.

Support OTA remote upgrade and data interconnection to achieve continuous iteration and remote diagnosis and maintenance of the chassis system.

Whether it's automatic parking or adaptive cruise control, an intelligent chassis is needed to accurately execute various commands, allowing technology to truly serve people.

The intelligent chassis provides a reliable execution foundation for autonomous driving technology through closed-loop control of "perception decision execution".

In short, intelligent chassis has evolved cars from traditional means of transportation to intelligent companions who understand what people think and need.

It is an inevitable trend for the future development of automobiles to comprehensively improve the safety, comfort, energy efficiency, and intelligence level of vehicles through technological integration.
