Vehicle Tachograph Wireless Remote Control Segmentation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current vehicle information systems and digital tachographs require fixed operator control elements and user guidance, limiting flexibility in installation location and customization, with user guidance frozen at production and not easily adaptable post-delivery.
Innovation Solution
A system comprising a digital tachograph with a detachable receiver module and wireless remote control for independent control, allowing customizable operator control and user guidance, enabling control from any location and design changes post-installation, using Bluetooth interface for wireless data transmission and multiple remote controls for sector-specific operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If operator control elements are integrated directly into the tachograph, then control reliability is improved, but installation location flexibility deteriorates
Solution Approach 1:
The system separates the tachograph into two independent parts: the permanently installed tachograph unit and a detachable remote control unit. The remote control can be placed at any location in the vehicle cockpit, while the tachograph remains fixed, resolving the contradiction between reliable integrated control and installation flexibility.
Solution Approach 2:
A wireless communication interface acts as an intermediary between the remote control and the tachograph. This mediator transmits control signals and data between the two units, enabling reliable control functionality to be accessed from any location without physical integration.
2Stability of the object's composition
If user guidance is frozen at production, then system stability is improved, but post-delivery adaptability deteriorates
Solution Approach 1:
The user guidance system transitions from a static, frozen state to a dynamic, configurable state. Multiple user guidance versions can be stored in the tachograph's memory, and the appropriate version can be selected and activated based on the specific vehicle or operator needs, allowing post-delivery adaptation while maintaining system stability.
3Adaptability or versatility
If multiple remote controls with different inputs are provided, then user-specific customization is improved, but device complexity deteriorates
Solution Approach 1:
The remote control is designed as a universal device that can be configured for different users and functions. Rather than creating multiple specialized remote controls, a single multi-functional remote control unit is provided that can be programmed with different user guidance versions and input mappings, reducing overall system complexity while maintaining customization capabilities.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables flexible and customizable operator control of tachographs, allowing user-specific guidance and control of multiple appliances without requiring redesign of vehicle architecture, facilitating post-delivery modifications and enhanced user experience.
Implementation Method 1
The remote control (3, 4) is set up for wireless data transmission with the receiver module (2)
Data Source
AI summary
A system for collecting operating data of a vehicle, including a digital tachograph that can be installed rigidly in the vehicle, and a receiver module for receiving data for controlling the tachograph. The module is removalby connected to the tachograph by way of an interface prescribed by the tachograph. At least one remote control is equipped with a transmitter for operating the tachograph the remote control being adapted to wirelessly transfer data using the receiver module.
