Abstract

Method for monitoring the permissible speed and the permissible distance between motor vehicles in road traffic by radio transmission of data for identifying the vehicles and their speed to a receiving station, characterized in that the data for describing the identity and speed of the motor vehicles to be monitored originate from a measuring system with a coupled transmitting device installed in each of the motor vehicles to be monitored, wherein the measuring system is the online on-board system (OBD system) for all motor vehicles with combustion and/or electric motors, and wherein the data for identifying the motor vehicles by the respective vehicle identification number (VIN) and the respective vehicle speed are taken from the OBD system installed in each motor vehicle.

Description

The road traffic regulations stipulate, in essence, that motor vehicles must travel at appropriate speeds in public road traffic. This includes, in particular, compliance with the locally permitted maximum speed. To ensure this can be done objectively, all motor vehicles are equipped with speedometers and speed displays. Motor vehicle drivers often unconsciously and frequently also consciously ignore the maximum speed limits indicated by traffic signs and the general permissible speed limits, which can lead to hazards, accidents and traffic obstructions. Driving too fast and following too closely together results in traffic accidents, leading to significant intangible and material damage. Autonomous and semi-autonomous vehicles are programmed to avoid risks and thus accidents. If individual vehicles approach, merge into, or move within the flow of traffic too quickly, the autonomous vehicles are more likely to reduce their speed or brake suddenly to minimize the risk of a collision than to wait under a higher risk of collision and hope that "nothing happens." The consequence of these expected characteristics of autonomous vehicles in a mix of conventional vehicles and individual "reckless" drivers is undesirable traffic jams. In autonomous road vehicles, their driving behavior depends on the surrounding stationary objects, such as the road layout and markings, moving and stationary vehicles, traffic signs, and all other moving objects, such as pedestrians and animals. The autonomous vehicle continuously calculates the vectorial velocities of all these objects and, using its own velocity vectors, determines the probability of a collision. Based on these values, it then makes possible corrections to its driving behavior to minimize the risk of a collision. This means that in the coming decades, traffic will consist of a mix of autonomous and human-driven vehicles. This situation requires a high degree of discipline, which, based on experience, many people will not submit to voluntarily. A significant increase in monitoring measures would improve overall road safety discipline and greatly simplify, if not enable, the desired diverse use of autonomous vehicles. Even though autonomous vehicles already exist, they will never account for 100% of all traffic in the near future because people like to be active. Not everyone uses trains and buses today either. Since discipline is a prerequisite for smooth and accident-free coexistence in road traffic, an educational steering force must be generated. This steering force is significantly enhanced by the present invention through technical innovations. Another aspect to consider when thinking about autonomous vehicles in a swarm of conventional vehicles is the distance between them. It can be observed that in heavy traffic, the distances between vehicles are significantly smaller than the recommended safety distances. Chain-reaction collisions demonstrate that drivers are undisciplined and inattentive. Therefore, autonomous vehicles will maintain a greater distance from the vehicle in front of them in a swarm of conventional vehicles and will consequently be slower. In this sense, autonomous vehicles act as disruptors in the undisciplined flow of traffic. Ideally, drivers of conventional vehicles should be educated to maintain sufficient distances from the vehicle in front, in order to achieve a smooth flow of traffic with fewer risks of rear-end collisions. Current solutions to the problem To determine the speed of motor vehicles for police monitoring, a measuring device is generally required. There are various measuring devices, e.g., compressed air hoses. Speed cameras are used on the roadway, light barriers beside the roadway, and mobile and permanently installed radar systems with lasers or radio beams positioned in front of or behind vehicles, beside or above the roadway. These radar systems are often equipped with cameras to identify drivers and license plates. In the utility model specification DE 20 2016 004 211 U1 It is proposed that the license plate numbers of motor vehicles be transmitted to a police station via a general radio device in the vehicle when a speeding violation is detected by conventional speed measurement and a radio command for transmission is triggered by the measuring station. This would enable the monitoring of cars, trucks, and motorcycles from the front. In the disclosure document DE 10 2007 050 677 A1 It is proposed that vehicles, based on a GPS navigation principle and suitable software, should detect violations of the road traffic regulations and report the violation directly, at least to a government agency, so that the violation can be punished. In the disclosure document DE 10 2018 210 852 A1 A procedure for detecting unlawful driving behavior is described in which the vehicle's environment is recorded by vehicle sensors, an environment model is created based on the sensor data, unlawful behavior is recognized from the environment
