Description

2.1. Technical field

[0001] The present invention relates to vehicle electronics and systems for the visual indication of dynamic vehicle parameters, in particular speed. It can be used in both external and internal lighting modules of cars, motorcycles and other means of transport. 2.2. State of the art

[0002] Various lighting systems for vehicles are known, including decorative ambient lighting in the interior, external LED modules, and devices that obtain speed data via GPS or the OBO-II interface. Such systems typically serve an aesthetic function or digitally display the speed and do not offer adaptive changes to the color, brightness, and / or geometric parameters of the light emission depending on the dynamic motion characteristics.

[0003] No solutions are known that simultaneously exhibit the following characteristics: - Functions both inside and outside the means of transport; - Use of data on speed, acceleration and deceleration from various sources (OBD-II, CAN, GPS, etc.); - Generation of an intuitive color indication that is perceived through peripheral vision; - Ensuring adaptive transitions of color, brightness and illuminated area in real time; - Feasibility in the form of internal modules (ColorSpeed ​​Inside) or external modules (ColorSpeed ​​Outside) in a single system. 2.3. Object of the invention

[0004] The object of the invention is to create a universal adaptive system for the light indication of dynamic vehicle parameters, which is intended for both internal and external placement and increases road safety through the immediate visual transmission of information about speed and other motion characteristics.

[0005] The system solves the following subtasks: 1. Internal modules (ColorSpeed ​​Inside): - Providing an intuitive color indication of speed for the driver, perceived through peripheral vision without having to look away from the instrument cluster; - Reduction of the likelihood of unintentional speeding, especially in 30-50 km / h zones; - Increased safety for older and novice drivers through simpler sensory input (color instead of numbers); - Reduced reaction time to speed changes through smooth color transitions and automatic brightness adjustment. 2. External modules (ColorSpeed ​​Outside): - Providing visual cues about the vehicle's dynamics (acceleration, deceleration, speed) to other road users; - Increased safety when overtaking, changing lanes and in poor visibility conditions (rain, twilight, fog); - Enabling pedestrians and other drivers to estimate the speed of an approaching vehicle; - Independent function of the standard headlights and taillights, without affecting their functions. 3. Universality and technical adaptability: - Approval of the use of various data sources: OBD-II, CAN bus, GPS, accelerometer, radar, etc.; - Automatic adjustment of color, brightness and geometry of the lighting depending on speed, acceleration, braking and environmental conditions; - Ensuring compatibility with various vehicle types (cars, motorcycles, scooters, etc.); - Enabling installation without altering the standard appearance. Key effect of the invention:

[0006] Increased road safety for drivers, pedestrians and the surroundings through fast, distraction-free, adaptive color indication of dynamic parameters, available both inside and outside the vehicle. 2.4. Solution to the task

[0007] The invention relates to an adaptive light display system for dynamic vehicle parameters, designed to display information about speed, acceleration, deceleration and other motion characteristics by changing the color, brightness and / or geometric parameters of the light emission.

[0008] The system includes: - a unit for capturing motion parameters that is capable of obtaining data from one or more sources, including OBD-II, CAN bus, GPS, accelerometers, ABS sensors, transmission speed sensors, radar, smartphone and other compatible sources; - a control unit designed for real-time data processing, generation of control signals, implementation of algorithms for adaptive color logic, automatic brightness control and software updates; - one or more light modules based on controllable lighting technology (RGB / RGBW, COB, LED, OLED, fiber optics, etc.), installed both inside and outside the vehicle and intended to provide information for the driver or other road users to perceive.

[0009] The system does not output any textual, graphic, or numerical elements, but transmits information exclusively through adaptive color indication, which is perceived through direct or peripheral vision. 2.5. Examples of Implementation

[0010] The internal version of the system (ColorSpeed ​​Inside) can be implemented as a narrow LED strip along the lower edge of the windshield or in the dashboard trim. The light module generates a continuous color gradient that indicates the speed (e.g., blue for low speed, green for the speed limit in urban traffic, and yellow / red for speeding). The external version (ColorSpeed ​​Outside) can be implemented as a ring-shaped LED element around the license plate holder and indicate the current vehicle dynamics (e.g., pulsating yellow during hard acceleration or a smooth transition to dark red during hard braking) to following traffic. 2.6. Commercial Applicability

[0011] The system is suitable for industrial applications because it can be manufactured using readily available electronic components (microcontrollers, RGBW LEDs, OBD-II interfaces). The product is suitable as an aftermarket retrofit solution for virtually all modern vehicles with an OBD-II connector. Its simple installation and the high demand for road safety solutions guarantee its commercial viability.
