1Object-generated harmful factors
If hard-material coated brake discs and special pads are used to reduce brake emissions, then brake wear emissions are reduced, but vehicle hardware costs increase
Solution Approach 1:
The patent replaces mechanical/physical brake emission reduction solutions (hard-material coatings, special pads) with a software-based navigation system that predicts and optimizes routes to minimize braking actions. The controller uses forecast models and traffic data to select alternative routes, thereby reducing brake wear emissions without any physical modifications to the brake system, eliminating additional hardware costs.
2Object-generated harmful factors
If a software-based prediction system is implemented to optimize brake wear emissions, then emission reduction effectiveness is improved, but system complexity increases
Solution Approach 1:
The patent integrates the brake emission prediction and optimization functions into the existing navigation system of the vehicle. The controller utilizes already-available traffic data, route information, and vehicle parameters to perform brake action predictions. This multi-functional approach allows the system to serve both navigation and emission optimization purposes without requiring completely separate hardware or software components, thereby managing complexity while achieving emission reduction.
