Wireless Driving Pattern Selection via Smartphone Terminal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle driving pattern selection methods, such as physical switches, are inconvenient for updating or adding new modes, limiting user flexibility and convenience.
Innovation Solution
A vehicle driving control system that uses a terminal, like a smartphone or navigation, to select and transmit driving pattern modes and control information to a vehicle controller via a transceiver, allowing for adaptable and updateable driving patterns, including eco and sports modes, using communication protocols like Bluetooth, Zigbee, or NFC.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a physical selection switch is installed in the vehicle for choosing driving pattern modes, then the driver can directly select driving patterns, but the system becomes difficult to update when additional modes are generated or corrections are needed
Solution Approach 1:
The patent replaces the mechanical selection switch with a software-based system using a terminal device (smartphone, tablet, or in-vehicle infotainment system). The terminal communicates with the vehicle controller through wireless or wired connections, allowing driving pattern selection to be controlled via software interface rather than physical switch. This substitution enables remote updates and additions of driving patterns without hardware modifications.
Solution Approach 2:
The terminal device serves multiple functions: it acts as the selection interface for driving patterns, provides communication bridge between user and vehicle controller, and enables updates to the driving pattern database. The vehicle controller also performs multiple roles by receiving commands from the terminal, processing driving pattern selections, and controlling various vehicle subsystems (engine, transmission, brakes) according to selected patterns.
2Ease of operation
If a selection switch is installed within the vehicle for determining driving pattern mode, then direct control is available, but the device complexity increases and convenience is reduced
Solution Approach 1:
The patent extracts the driving pattern selection function from the vehicle's internal hardware and relocates it to an external terminal device. The terminal handles the user interface and selection logic, while the vehicle controller focuses on executing the selected pattern. This separation reduces the complexity of the vehicle's control system by removing the need for dedicated physical switches and associated wiring.
Solution Approach 2:
The terminal device acts as an intermediary between the user and the vehicle controller. Instead of the user directly manipulating vehicle-mounted switches, the terminal provides a more convenient interface (touchscreen, buttons, or voice recognition) and transmits the selection to the vehicle controller through communication protocols. This intermediary layer simplifies the overall system architecture while enhancing user convenience.

AI summary
A vehicle driving control system and method for selecting a driving pattern using a predetermined program (or application) and for operating vehicle driving via a terminal that provides driving information of the selected driving pattern. The vehicle driving control system may include a terminal configured to transmit a selected driving pattern mode and driving pattern control information on the selected driving pattern mode to a vehicle controller when a predetermined vehicle driving pattern control program is executed. A vehicle controller is configured to operate an object of a vehicle related to driving based on the driving pattern mode and the driving pattern control information transmitted by the terminal. A transceiver is configured to transmit and receive signals between the terminal and the vehicle controller.
