Brake Control Device for Commercial Vehicle Load Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Commercial vehicles face safety risks due to insufficiently secured loads and improperly positioned vehicle parts, which can lead to unstable driving conditions, and existing solutions either require human intervention or are costly.
Innovation Solution
A fully automatic brake system control device integrated with a monitoring sensor that recognizes unsafe conditions and initiates light braking pulses or real braking to warn the driver and ensure safe conditions, without the need for separate manual valves, using existing sensors where possible.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a separate valve controlled by hand is used to activate the vehicle's brake, then the braking function can be activated, but the device complexity and human intervention requirements increase
Solution Approach 1:
The patent merges the monitoring function and braking activation function into a single integrated control device. The control device receives signals from monitoring sensors and automatically activates brakes without requiring separate manual valves or additional control components, thus reducing device complexity while achieving full automation.
Solution Approach 2:
The brake system is designed to self-activate based on sensor inputs. When the monitoring sensor detects an unsafe condition, the control device automatically triggers the braking mechanism without human intervention, making the system self-serving and fully automated.
2Reliability
If a monitoring sensor and control device extension are added to the brake system, then automatic recognition of unsafe conditions is achieved, but the apparatus cost increases
Solution Approach 1:
The control device is designed with multi-functionality, serving both as the existing brake control unit and as an unsafe condition recognition system. By integrating the monitoring and control functions into the same device, the patent avoids the need for entirely separate sensor systems and control units, thereby reducing apparatus complexity while maintaining high reliability.
3Ease of operation
If light braking pulses are used as a warning signal, then the driver is alerted without significant deceleration, but the braking effectiveness is reduced
Solution Approach 1:
The patent employs periodic braking pulses instead of continuous braking. These pulsed brake applications serve as warning signals to alert the driver through intermittent deceleration events, allowing the driver to maintain awareness of the unsafe condition while avoiding continuous strong braking that would cause significant deceleration and potentially disrupt normal driving operations.

AI summary
The invention relates to a method for controlling a compressed-air-controlled brake system of a utility vehicle (3, 4), wherein a monitoring sensor (S) monitors whether the means for securing or positioning a vehicle part of the utility vehicle (3, 4), a cargo (6) of the utility vehicle (3, 4) or a cargo carrier (7, 10) which accommodates a cargo (6) of the utility vehicle (3, 4), which are provided in order to ensure a safe driving state of the utility vehicle (3, 4), are present and wherein the brakes (B) of the utility vehicle (3, 4) are actuated automatically if the monitoring sensor (S) detects that the means for securing or positioning the vehicle part, the cargo (6) or the cargo carrier (7, 10), which are provided in order to ensure a safe driving state of the utility vehicle (3, 4), are not present. The invention also relates to a system composed of a brake system control device for such a brake system and a monitoring sensor as well as a brake system control device for this purpose.
