Interactive Automated Driving System with Dynamic Target Ranges
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current automated driving systems lack the ability to adapt to individual driver preferences and behaviors, leading to potential inefficiencies and safety concerns, especially in dynamic traffic conditions like stop-and-go traffic, where drivers may want to adjust vehicle spacing.
Innovation Solution
An interactive automated driving system that uses sensors and a computing device to determine a current vehicle state, generate target vehicle state ranges based on driver inputs, and adjust vehicle operations within safe limits, allowing drivers to modify behavior while ensuring safety by maintaining or changing vehicle states within predefined ranges.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the automated driving system operates with fixed target values for vehicle control, then safety and consistency are maintained, but adaptability to individual driver preferences and dynamic traffic conditions deteriorates
Solution Approach 1:
The system implements dynamic target values that can be adjusted in real-time based on driver inputs and traffic conditions. The automated driving system transitions from static, pre-programmed target values to dynamic values that adapt within safe operating ranges, allowing the vehicle to respond to driver preferences while maintaining safety boundaries.
Solution Approach 2:
The system changes operational parameters by introducing ranges of target values instead of fixed values. These parameter ranges allow flexibility in vehicle operation (such as spacing in stop-and-go traffic) while maintaining safety through defined boundaries. The system can adjust parameters like following distance, acceleration, and deceleration within acceptable ranges based on driver behavior.
2Ease of operation
If the system allows driver inputs to modify vehicle operation, then driver satisfaction and personalization improve, but system complexity and control difficulty increase
Solution Approach 1:
The system incorporates feedback mechanisms where driver inputs are continuously monitored and processed. The automated driving system receives feedback from driver actions (such as manual steering, acceleration, or braking inputs) and adjusts its control parameters accordingly, creating a closed-loop system that responds to driver behavior while maintaining overall safety.
Solution Approach 2:
The system achieves multi-functionality by combining automated control with driver input handling in a unified framework. The same control system manages both autonomous operation and driver-requested modifications, eliminating the need for separate systems and reducing overall complexity despite the enhanced capabilities.
3Speed
If the system maintains strict target values for vehicle control, then safety and predictability are ensured, but responsiveness to dynamic traffic conditions and driver needs deteriorates
Solution Approach 1:
The system employs dynamic target values that can adapt to changing traffic conditions while maintaining defined safety ranges. This allows the vehicle to respond quickly to dynamic situations (such as changing spacing in stop-and-go traffic) while ensuring that all adjustments remain within predictable and safe boundaries.

AI summary
A system, device, and methods of interactive automated driving are disclosed. One example method includes receiving a current value from one or more sensors disposed on a vehicle and determining a current vehicle state based on the current value. The method also includes generating a target vehicle state based on the current vehicle state and including a range of target values and generating a desired vehicle state. The desired vehicle state includes a desired value based on one or more driver inputs received at one or more vehicle interfaces. If the desired value falls inside the range of target values, the method also includes sending a command to one or more vehicle systems to change the vehicle state from the target vehicle state to the desired vehicle state.
