Abstract

The invention discloses an IMU signal simulation method applied to an IMU signal simulation system, the IMU signal simulation system comprises a simulation module and a video injection module, the IMU signal simulation method comprises the following steps: the simulation module obtains vehicle pose information and sends the vehicle pose information to the video injection module, the vehicle pose information comprises speed information and acceleration information of the vehicle in six degree-of-freedom directions; and the video injection module converts the received vehicle pose information into an IMU signal of a preset video protocol, and sends the IMU signal of the preset video protocol to the intelligent driving controller to be tested. The invention further discloses an IMU signal simulation system, IMU signal simulation equipment and a computer readable storage medium. According to the invention, the simulation of the IMU signal of the video protocol in the hardware-in-the-loop test or the real vehicle-in-the-loop test is realized.

Description

Technical field [0001] The present invention relates to the field of smart driving, particularly to a IMU signal emulation method, system, apparatus, and computer-readable storage medium. Background technique [0002] With the rapid development of intelligent drive technology, ADAS (Advanced Driver Assistance System, advanced driver assistance systems) are also increasingly popular. Domestic and foreign car manufacturers mainstream in the product development process were developed using a V-shaped pattern, the entire development process comprising the steps of: functional design and off-line simulation; rapid control prototyping; code generation; hardware in the loop simulation (Hardware-in-the -Loop, HIL); integration testing and calibration. And using the hardware emulation system ECU (Electronic Control Unit, Electronic Control Unit) HILS physical testing method of combining loop simulation testing, it is an important step in the product development process. Currently IMU (Ine...
