Vehicle Braking Control Software Wireless Flashing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current braking system control software is not adaptable to changes in vehicle type during production, leading to inefficiencies and increased inventory complexity, as it is typically fixed at the time of production and not updatable without workshop visits.
Innovation Solution
A method for managing control software in vehicle braking systems involves downloading and flashing vehicle-adapted software via a wireless interface, allowing for precise parameter establishment and updating, enabling the same hydraulic system to be used across different vehicle types, with a boot manager controlling the process and enabling over-the-air updates.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If control software is fixed at production time, then system reliability is ensured, but adaptability to vehicle type changes deteriorates
Solution Approach 1:
The control software transitions from a static state (fixed at production) to a dynamic state (updatable via wireless interface). The system allows the control software to be updated after production through a wireless download and flashing process, enabling adaptation to different vehicle types while maintaining system reliability through controlled update mechanisms.
Solution Approach 2:
The system changes the parameter of software updateability from false (fixed) to true (updatable). By implementing a wireless download interface and flashing mechanism, the control software can be modified after production, allowing the same hydraulic system to be adapted to different vehicle types without requiring physical reconfiguration.
2Reliability
If control software is updated in workshop visits, then software can be kept up-to-date, but productivity and customer convenience deteriorate
Solution Approach 1:
The braking system performs self-updating by automatically downloading and installing control software updates via a wireless interface. The control unit receives update commands and executes flashing operations autonomously, eliminating the need for workshop visits and allowing the system to maintain itself independently.
Solution Approach 2:
The manual update process (requiring workshop visits and physical intervention) is replaced by an automated electronic process. The wireless interface and automated flashing mechanism substitute for manual software updating, enabling over-the-air updates that improve productivity and customer convenience.
3Adaptability or versatility
If different hydraulic systems are used for different vehicle types, then vehicle-specific requirements are met, but device complexity and inventory management deteriorate
Solution Approach 1:
A single hydraulic system design is made universal by pairing it with updatable control software. The same physical braking system can be adapted to different vehicle types through software updates, eliminating the need for multiple hardware variants and simplifying inventory management while maintaining vehicle-specific control capabilities.
Solution Approach 2:
The vehicle-specific control parameters are extracted from the hardware and placed in the software. By moving the adaptability requirements from the physical hydraulic system to the software layer, the same hardware platform can serve multiple vehicle types, reducing device complexity and inventory burden.
