Innovation Solution
A method and device for controlling ADAS by calculating vehicle load and slope, comparing required vs. actual acceleration times, providing overload warnings, and adjusting ACC responsiveness and alarm timings to prevent accidents.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the ACC system uses fixed acceleration parameters, then the system is simple to implement, but it cannot adapt to overload conditions or slope variations leading to reduced safety
Solution Approach 1:
The ACC system dynamically adjusts acceleration parameters based on real-time detection of vehicle load conditions and slope information. The control device modifies the target acceleration values and alarm timings according to detected overload states and road gradients, transforming a static system into an adaptive one that responds to changing operational conditions.
Solution Approach 2:
The system implements feedback mechanisms by detecting actual acceleration performance and comparing it with expected values. When the vehicle fails to achieve expected acceleration due to overload or slope, the system receives feedback about this performance gap and adjusts control parameters accordingly, creating a closed-loop control system that continuously optimizes safety.
2Reliability
If the ACC alarm timings are fixed, then the control logic is simple, but it cannot provide adequate warning in overload or slope conditions leading to potential accidents
Solution Approach 1:
The alarm timing mechanism transitions from fixed to dynamic by adjusting warning intervals based on detected load conditions and slope. In overload conditions or when ascending slopes are detected, the system extends alarm timings to provide earlier warnings, allowing the driver more time to respond to potential safety issues.
3Measurement precision
If the system detects overload by comparing acceleration timing, then it can identify overload conditions, but it requires additional processing time affecting responsiveness
Solution Approach 1:
The system performs preliminary detection of load conditions by monitoring acceleration patterns from the start of vehicle movement. By establishing baseline acceleration expectations before full driving conditions are established, the system can quickly identify deviations indicating overload without requiring extended observation periods.

AI summary
The present disclosure relates to a method and a device for controlling an advanced driver-assistance system (ADAS) based on the load and the slope of a driving vehicle. The method may include calculating information on the load of the driving vehicle; transmitting a required acceleration while controlling an adaptive cruise control of the driving vehicle; comparing the time required to reach the required acceleration with the time required to reach an actual acceleration of the driving vehicle; transmitting a warning signal about overload to a driver based on the reaching time; calculating information on the slope on which the driving vehicle is traveling; and controlling the adaptive cruise control based on the information on the slope of the driving vehicle.
