Vehicle Controller Input Signal Routing for Call Response
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Low-cost vehicles often lack a dedicated operation device to respond to call signals from portable terminals, compromising driving safety as drivers must manually operate the terminal, which can distract from driving.
Innovation Solution
An apparatus and method that includes a communication device, sensors to detect driving and surrounding states, and a controller generating a second control signal to manage input device functions differently based on these states, allowing response to call signals without manual terminal operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a dedicated operation device is provided in the vehicle to respond to call signals, then driving safety is improved, but manufacturing cost increases
Solution Approach 1:
The input device is designed with multi-functionality, serving both as a general vehicle control input device and as a call signal response device. When a call signal is received and the vehicle is in a driving state, the controller generates a second control signal in response to operations on the input device, enabling call response without requiring a separate dedicated button or device. This eliminates the need for additional hardware while maintaining safety functionality.
Solution Approach 2:
The existing input device and controller system serve themselves by extending their functionality to handle call signal responses. The controller, already present for vehicle control, is configured to recognize call signal contexts and generate appropriate control signals based on input device operations, eliminating the need for separate dedicated response mechanisms.
2Device complexity
If the driver operates the portable terminal manually to respond to call signals, then device complexity is reduced, but driving safety deteriorates
Solution Approach 1:
The controller acts as an intermediary between the input device and the portable terminal. When the controller detects that a call signal is received and the vehicle is in a driving state, it intercepts operations on the input device and generates second control signals to respond to the call signal, preventing the driver from needing to manually operate the portable terminal during driving.
3Device complexity
If the input device is used for both preset functions and call signal response, then device complexity is reduced, but ease of operation deteriorates
Solution Approach 1:
The function of the input device is made dynamic rather than static. The controller dynamically determines whether to generate a first control signal (for preset functions) or a second control signal (for call signal response) based on real-time conditions such as whether a call signal is received and whether the vehicle is in a driving state. This dynamic adaptation allows the same input device to serve different purposes contextually without confusing the driver.
Solution Approach 2:
The system uses feedback from the communication device about call signal reception status and from sensors about vehicle driving state to dynamically adjust the function of the input device. This feedback mechanism ensures that the input device responds appropriately to different operational contexts, maintaining ease of use while enabling multiple functions.

AI summary
An apparatus of controlling a vehicle includes a communication device that communicates with a portable terminal, a sensor that detects a driving state and a surrounding state of the vehicle, and a controller that generates a second control signal different from a first control signal when the first control signal is not generated corresponding to the driving state, the surrounding state and an operation of an input device when a call signal is received at the portable terminal, the vehicle is in a driving state, and the input device is operated. Accordingly, even if a vehicle is not separately provided with an operation device for responding to the call signal received by the mobile terminal, the apparatus may respond to the call signal received by the portable terminal and be applied to low-cost vehicles, improving customer satisfaction and driving performance.
