According to the announcement of the State Intellectual Property Office, Alter Automotive Technology Co., Ltd. *** hereinafter referred to as "Alter") has applied for a patent entitled "A Power Domain Controller for Electric Vehicles and Motor Torque Control Method", with publication number CN117124870A and an application date of August 2023. The application for this patent marks IAT's continuous innovation and development in the field of electric vehicle technology.
According to Xuan Qiwu, the patent mainly relates to a power domain controller of an electric vehicle and a motor torque control method. This controller collects vehicle information and generates information related to the vehicle and the battery. In this way, the controller is able to generate demand torque information based on vehicle information and information related to the traction battery. Based on this information and the required torque information, the MCU function module then generates a torque control signal to control the motor to perform the required torque.
This method of power domain controller and motor torque control has many advantages. First of all, it avoids various problems that may arise during the use of CAN bus for transmission, such as increased CAN bus load rate and electromagnetic interference, which can lead to low fault tolerance and low accuracy of CAN bus. In this way, the technology significantly increases the accuracy of the relevant signals for torque calculation or torque control during transmission, which in turn increases the safety of the entire vehicle.
As a leading enterprise in the field of automotive design and development in China, IAT has been committed to promoting the development and innovation of China's leading enterprises. This patent application is a concrete embodiment of IAT's insistence on scientific and technological innovation, respect for talents, and customer service. Xuan Qiwu revealed that IAT will continue to provide a wide range of technical support and services for domestic and foreign automobile manufacturers in the fields of automobile design and development, engine and powertrain design and development, prototype car manufacturing, vehicle and parts testing, and production line improvement.
Xuan Qiwu said that the application for this patent is a major breakthrough in the field of electric vehicle technology, which not only improves the safety of electric vehicles, but also further promotes the development of China's electric vehicle industry. In the future, IAT will continue to introduce more innovative and practical technologies to make greater contributions to the development of the global automotive industry.
