[0002] The vehicle controller is an electronic device used to manage and control various systems and components of a car. It receives signals from sensors and other input devices, and then processes and analyzes these signals according to predetermined programs and algorithms, thereby achieving precise control of the acceleration, braking, steering and other operations of the car. As a type of vehicle controller, the vehicle controller is the core of the vehicle, responsible for processing the data collected by the sensors and making decisions based on the preset algorithms. The actuator performs corresponding operations according to the instructions of the control unit, including adjusting the acceleration, braking, steering and other functions of the vehicle. The vehicle communication system enables efficient information sharing between various modules, which plays an important role in realizing the intelligent coordination of vehicles. The vehicle controller is a key component of the electronic architecture of modern vehicles. It involves multiple technologies and applications, including powertrain, body electronics, infotainment, intelligent driving, etc. With the development of electric vehicles and autonomous driving technology, the functions and complexity of vehicle control systems are also constantly improving.

[0003] Existing vehicle controllers use real-time operating systems in large quantities. The controller algorithm is mounted on the controller thread using the default configuration, and cannot be adjusted as needed during the vehicle test process. As the vehicle algorithm becomes more and more complex, the controller algorithm may take a long time to run. Traditional real-time operating systems and measurement tools can only test the running time of tasks, but not the running time of controller algorithms. The controller algorithm running cycle uses the default configuration and cannot be changed, so the running time of the controller algorithm cannot be tested. Summary of the invention
