Motor controller software architecture based on AUTOSAR

Abstract

The invention discloses an AUTOSAR-based motor controller software architecture, which comprises an application software layer, an operation environment layer, a basic software layer and a microcontroller and hardware layer, and is characterized in that the application software layer is located at the topmost layer and is used for carrying out vehicle information interaction, operation control algorithm, fault diagnosis algorithm and logic operation design according to the requirements of a motor controller; the operation environment layer is located between the application software layer and the basic software layer and used for bidirectionally transmitting data and information between the two layers through a preset interface function according to the requirement of a motor controller and managing data and information in the two layers. The basic software layer provides storage service and diagnosis service required by motor control for the application software layer, performs unified packaging on the microcontroller and the hardware layer, and simultaneously undertakes and completes a task required by high real-time performance in the motor controller. According to the framework, the portability of overall upper-layer software of the motor controller, the high decoupling performance of bottom-layer hardware and software and the high safety of the overall framework are improved.

Description

technical field [0001] The invention relates to the technical field of automobile software architecture and electric vehicle drive motor controller, in particular to an AUTOSAR-based motor controller software architecture. Background technique [0002] In recent years, the degree of electrification and electronics of automobiles has been continuously improved, the number of controllers and software functions has increased sharply, and the hardware platforms have become diversified, resulting in low software reusability and increased development costs. In order to solve these problems, in 2003, nine giants in the automotive industry worked together to propose an open and standardized software architecture for the automotive industry, namely the automotive open system architecture AUTOSAR. At present, it has become the main trend for automobile enterprises to use the AUTOSAR standard architecture to define control software. Many Chinese manufacturers have also become members ...

AI Technical Summary

Problems solved by technology

In the field of electric vehicle drive motors, with the gradual advancement of intelligent control trends, the number of functional modules of motor controllers continues to increase, and the software becomes more and more complex. Developers also have a variety of choices, while traditional motor controllers have serious coupling between software and hardware. , does not have the portability and reusability of either end, resulting in low development efficiency, so decoupling software architecture design is an inevitable trend

[0003] In the existing AUTOSAR research on the software architecture of the motor controller, it is mainly aimed at a specific functional requirement in the motor, such as the field-oriented vector control of the motor. The further priority relationship between the software, the interaction between the controller software and the hardware does not make full use of the resources of the other layers in the AUTOSAR architecture other than the application layer, and there is no special design for the high real-time requirements of the motor operation.
