Standards Development
This document specifies the test method and performance indicators to evaluate the behaviour of a vehicle equipped with a rear cross traffic alerting system. The overall test method for the rear cross traffic alerting system includes the specifications of the test objects, the accuracy of the test equipment measurements, the test environment requirements, and types of test scenarios. This document applies to M1 category vehicles. The requirements of rear cross traffic alerting system are not in the scope of this document.
A significant amount of traffic accident data indicates that drivers often fail to observe the traffic situation behind their vehicle while reversing, which can easily lead to accidents. This not only poses a threat to the safety of the drivers themselves but also endangers the safety of pedestrians and other vehicles on the road. The rear traffic warning system for passenger cars is an advanced driving assistance technology that enhances active safety. When the driver is reversing in a crowded area, if the running route of the moving vehicle behind the car is crossed, the prompt information is sent to the driver in time, effectively reducing the occurrence of collision accidents and improving the safety of reversing. However, there is currently no international standard for testing the effectiveness of rear traffic crossing warning systems in passenger vehicles, and there is also a lack of standardized test scenarios for these systems. The global automotive industry cannot rely on a uniform test method for testing and validation. Therefore, we propose establishing a standardized RCTA test method to improve the active safety performance of vehicles and enhance road traffic safety. The purpose and benefits of this project will be: - To tackle the challenges that OEMs face during development due to the absence of a unified test methodology. - To solve the problem that the RCTA system cannot be tested and verified through unified scenarios and test methods. - To establish a fundamental agreement on the definition of terms and testing methods related to the RCTA system, in order to create a basis for knowledge sharing and technical collaboration among countries.
