Vehicle Driving Time Optimization via Delayed Startup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current driver assistance systems fail to optimize driving times effectively within the constraints of tachograph regulations, particularly in traffic jams, leading to unnecessary accumulation of driving time due to the inability to accurately monitor and manage short driving maneuvers.
Innovation Solution
A method that utilizes sensors to compare driving time within a recording interval to a maximum permissible time, delaying startup to ensure the interval ends within the permissible limit, and providing signals to the driver for optimal starting, allowing for autonomous or immediate start-up based on predefined conditions, thereby optimizing driving time without exceeding regulatory limits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If the vehicle starts immediately when traffic moves, then the vehicle can maintain flow and reduce waiting time, but the driving time accumulates and may exceed maximum permissible limits
Solution Approach 1:
The system performs preliminary analysis of the traffic situation and driving time accumulation before the driver needs to make a decision. It calculates in advance whether starting the vehicle would cause the driving time to exceed maximum permissible limits, and provides advance warning to the driver, enabling proactive rather than reactive time management
Solution Approach 2:
The system continuously monitors the actual driving time against maximum permissible limits and provides real-time feedback to the driver through warnings or signals. This closed-loop feedback mechanism allows the driver to adjust behavior based on current status, preventing driving time violations while optimizing vehicle operation timing
2Duration of action of moving object
If the vehicle delays startup to comply with driving time limits, then driving time is optimized, but the vehicle may impede traffic flow or fail to respond to urgent situations
Solution Approach 1:
The system dynamically adjusts the optimal startup timing based on real-time conditions including traffic flow, driving time accumulation, and environmental factors. Rather than applying a fixed delay rule, the system continuously optimizes the startup moment to balance driving time compliance with traffic flow maintenance, adapting to changing conditions
3Reliability
If the driver manually monitors driving time, then compliance can be achieved, but the complexity of monitoring narrowly defined specifications increases and savings are left to chance
Solution Approach 1:
The system performs self-monitoring of driving time parameters, automatically calculating actual driving time, comparing it against maximum permissible limits, and generating warnings without requiring driver intervention. The tachograph and control unit work autonomously to ensure compliance, reducing the cognitive burden on the driver while maintaining high reliability
4Duration of action of moving object
If autonomous braking is used to manage driving time, then driving time can be controlled, but the system can only be activated during pause mode and may endanger following traffic
Solution Approach 1:
The system is designed to function across multiple operational modes including both pause mode and active driving mode. Rather than being limited to pause mode only, the driving time optimization and warning functions operate continuously regardless of vehicle state, making the system universally applicable to all driving scenarios while maintaining safety
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
This approach minimizes registered driving time by allowing vehicles to wait within permissible limits during traffic jams, providing drivers with reliable information on remaining driving time and enabling adaptive management of driving times, thus optimizing vehicle operation within legal frameworks.
Implementation Method 1
The core of the driver assistance systems described above are radar sensors, the task of which is to detect objects and to determine their speed and position
Implementation Method 2
The relative speed and distance of an object to the vehicle carrying the radar sensor is determined using the so-called Doppler effect, ie the frequency shift between the transmitted and the received signal

AI summary
The invention relates to a method for optimizing driving time in vehicles, wherein the driving time is recorded within a time recording interval and compared with a maximum permissible driving time within that interval, and wherein, if the maximum permissible driving time is adhered to, the time recording interval is not registered as driving time. According to the invention, it is provided that, when a vehicle is stationary, the driving time accrued within a time recording interval is compared with a maximum permissible driving time within that interval, and that, if a permissible remaining driving time is detected, the vehicle delays starting to move for such a period that, after starting to move again, the end of the maximum permissible driving time coincides with the end of the time recording interval, and that means are provided to signal readiness to start moving while adhering to the maximum permissible driving time.Furthermore, a suitable device is proposed for carrying out a procedure.
