Vehicle Powertrain Control via Wireless User Interface
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing powertrain control systems in vehicles cannot dynamically adjust to customer preferences regarding fuel economy, torque, and power output, as the default settings may not match individual user needs, which can change over time or depending on usage scenarios.
Innovation Solution
A system comprising a communication module and a control module that allows users to adjust powertrain operation, noise levels, and display settings via a user interface device, with remote server-enabled wireless communication to update powertrain control parameters, enabling customizable fuel economy, torque, and power output based on user preferences and scheduled periods.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If default powertrain control settings are used, then the system operates with fixed parameters, but it cannot adapt to individual user preferences or changing usage scenarios
Solution Approach 1:
The patent implements dynamic adjustability of powertrain control parameters by allowing users to select between different operational modes (e.g., fuel economy, sport, flat terrain, hill climb) that modify throttle response, transmission shift points, and engine mapping in real-time, transforming a static system into one that adapts to varying user needs and driving conditions
Solution Approach 2:
The system enables parameter changes by allowing users to modify key powertrain control parameters such as throttle body positioning, transmission gear selection, engine torque curves, and fuel injection timing through a user interface, thereby changing the operational characteristics of the powertrain to match individual preferences without altering the physical hardware
2Ease of operation
If fixed powertrain control parameters are used, then the system is simple to operate, but it cannot provide customized performance for different user needs
Solution Approach 1:
The patent segments the powertrain control system into distinct operational modes (fuel economy mode, sport mode, flat terrain mode, hill climb mode), each with pre-configured parameter sets that optimize performance for specific driving scenarios, allowing users to easily select the appropriate mode without needing to understand complex individual parameter adjustments
3Adaptability or versatility
If multiple user profiles and adjustable parameters are implemented, then user satisfaction improves, but the communication and control system becomes more complex
Solution Approach 1:
The communication module is designed with multi-functionality to handle diverse communication protocols and data formats, enabling it to interface with various user devices (smartphones, tablets, key fobs) and process different types of commands (parameter adjustments, profile selections, mode changes) through a single integrated system that can adapt to multiple communication standards

AI summary
A system according to the principles of the present disclosure includes a communication module and a control module. The communication module transmits a first wireless signal indicating a request from a user of a vehicle to adjust operation of a powertrain in the vehicle, a display in the vehicle, and/or a noise actuator in the vehicle. The communication module receives a second wireless signal enabling operation of the powertrain, the display, and/or the noise actuator to be adjusted according to the request. The control module controls the powertrain, the display, and/or the noise actuator based on a first set of values for a control parameter before the second wireless signal is received. The control module controls the powertrain, the display, and/or the noise actuator based on a second set of values for the control parameter after the second wireless signal is received.
