According to HORIBA MIRA, with physical vehicle testing becoming increasingly time-consuming, resource heavy and expensive, scenario-based testing is vital to improve the efficiency and cost of verifying and validating CAVs. It is often cited that billions of miles are required to demonstrate confidence in CAV systems, (Source – RAND Report) which is seen as non-viable for vehicle manufacturers with multiple product types and model variants, and for technology companies with short development and product lifecycles.
This approach is already being supported by several government-supported initiatives in which HORIBA MIRA have played a key role, including the SAVVY and HumanDrive projects.
As part of both projects, HORIBA MIRA has developed unique processes to evolve vehicle and regulatory requirements into a comprehensive set of testable scenarios, that will validate and verify the performance of the CAV systems. The range of test scenarios developed will ensure that CAVs can perform functionally and safely both in normal operation and in unexpected situations.
As these projects develop, HORIBA MIRA has said it is essential that a ‘quality over quantity’ approach is taken when it comes to evaluating the number of miles completed during the development of CAV systems – and the use of scenario-based testing is becoming essential in demonstrating vehicle safety.
