Commercial Vehicle Navigation Device with Weight-Dependent Driving Ban Avoidance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Commercial vehicle navigation devices do not adequately account for date- and vehicle weight-dependent driving bans, leading to potential penalties and fines for drivers who unknowingly violate these restrictions.
Innovation Solution
A navigation device with a control device connected to an information device storing date- and vehicle weight-dependent driving ban information, allowing for optimized route determination and display of relevant bans, along with alternative routes that comply with these restrictions, enabling drivers to avoid prohibited sections and plan detours effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the navigation device displays information on date- and vehicle-weight-dependent driving bans, then driver compliance and penalty avoidance improve, but device complexity increases
Solution Approach 1:
The patent combines multiple functions (route optimization, driving ban information storage, date/vehicle weight data management, and alternative route calculation) into a single integrated navigation device. This merging approach improves reliability by ensuring all parameters work together cohesively while managing complexity through unified system architecture rather than separate components.
Solution Approach 2:
The navigation device is designed as a multi-functional system that not only provides route optimization but also stores and processes driving ban information, vehicle weight data, and date information. This universal approach allows the device to handle multiple tasks (compliance checking, route planning, information display) within a single system, improving driver compliance without proportionally increasing complexity.
2Reliability
If alternative routes complying with driving bans are provided, then penalty avoidance improves, but calculation time increases
Solution Approach 1:
The navigation device performs preliminary calculations by pre-identifying and storing alternative routes that comply with driving bans before the driver needs them. When a driving ban is detected on the current route, the system can immediately present pre-calculated alternative routes, reducing the time penalty while ensuring compliance.
Solution Approach 2:
The system dynamically adjusts route calculations based on real-time parameters such as current date, vehicle weight, and detected driving bans. Rather than calculating all possible routes statically, the system dynamically generates alternatives only when needed and optimizes them based on current constraints, balancing calculation time with compliance reliability.

AI summary
The invention relates to a method for assisting the driver of a vehicle, in particular a commercial vehicle, wherein a navigation device (7) is provided by means of which a route optimized with respect to at least one optimization parameter is determined and displayed to the driver. According to the invention, when determining the optimized route, date- and vehicle-dependent, in particular date- and vehicle-weight-dependent, driving bans on defined sections of the route are taken into account. Alternatively and/or additionally, the navigation device (7) displays information to the driver regarding relevant date- and vehicle-dependent, in particular date- and vehicle-weight-dependent, driving bans on the determined route.
