Vehicle Utility Mode Control for Selective Function Powering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In electric vehicles, the utility mode causes unnecessary battery discharge as convenience devices remain in a standby state for extended periods, leading to increased battery drain.
Innovation Solution
A device and method for controlling a vehicle that allows only user-selected functions to operate in utility mode, and automatically selects functions based on vehicle location and environment, thereby turning off unselected functions to prevent battery discharge.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If all convenience devices are controlled to be in standby state in utility mode, then user convenience is improved, but battery discharge amount increases
Solution Approach 1:
The convenience devices are segmented into multiple groups (first group and second group) based on their operational characteristics and user selection patterns. The processor selectively controls power supply to different groups, allowing only the first group to operate in standby state while cutting power to the second group, thereby reducing overall battery discharge while maintaining essential user convenience functions.
Solution Approach 2:
Different power control strategies are applied to different device groups based on their specific characteristics. The first group of devices receives continuous power supply to maintain standby functionality for essential user needs, while the second group has power cut off to minimize energy consumption. This localized differentiation resolves the contradiction between maintaining user convenience and reducing battery discharge.
2Duration of action of moving object
If convenience devices remain in standby state for extended periods, then user accessibility is improved, but unnecessary battery discharge occurs
Solution Approach 1:
The power supply control strategy is made dynamic based on user selection. When the utility mode is activated, the processor dynamically determines which device groups should remain in standby and which should have power cut off. This dynamic adaptation allows the system to maintain device availability for essential functions while minimizing unnecessary energy consumption from non-essential devices.
Solution Approach 2:
The unnecessary power consumption is extracted by identifying and isolating the second group of convenience devices that do not require continuous operation. The processor extracts these devices from the power supply network while maintaining power to the first group, thereby eliminating unnecessary battery discharge while preserving essential device availability.
3Adaptability or versatility
If all functions are kept active in utility mode, then functional completeness is improved, but battery life decreases
Solution Approach 1:
The complete set of convenience device functions is segmented into two categories: essential functions (first group) and non-essential functions (second group). The processor maintains power supply to essential functions to preserve functional completeness while cutting power to non-essential functions to extend battery life, achieving a balanced operational state.
Solution Approach 2:
The power supply parameter is changed selectively for different device groups. The processor modifies the power state parameter from 'standby' to 'cut off' for the second group of devices while maintaining 'standby' for the first group. This parameter differentiation allows the system to maintain essential functionality while extending battery life by reducing overall power consumption.

AI summary
A device for controlling a vehicle includes an input device that receives an input of a user, and a processor that determines whether to supply power to a first controller for controlling a function selected based on a selection scheme and a second controller for controlling an unselected function when a utility mode is activated based on the input of the user and then the selection scheme for selecting a function to be used among functions controllable in the utility mode is set.
