Integrated Driving Technology for Electric Vehicles

By Jinyue Tian PhD

Integrated Driving Technology for Electric Vehicles reviews and provides analysis of the integrated power transmission technology of electric vehicles. Based on the external characteristics of the motor, the parameters and performance design requirements of the vehicle, the driving form of the motor integrated transmission is selected, and the power, torque, speed of the driving motor and the gear number and speed ratio of the transmission are matched and calculated.

The content of this book includes parameter matching between the drive motor and transmission, motor selection and design, transmission design, powertrain coupling control method, braking method for powertrain gear integration control shifting schedule, requirements and optimization techniques for shifting process, etc. The book argues that on the basis of ensuring the power performance requirements of automobiles, the energy utilization efficiency of electric vehicles can be improved through preliminary parameter matching of motors, transmission systems, and power batteries. Integrated control of electric vehicle power transmission system refers to the application of electronic technology, with electronic control unit (ECU) as the core, to achieve automatic operation of vehicle starting and shifting by controlling the actuator and controlling the power transmission system through electronic devices. The book shows readers to understand the basic working principles of integrated transmission control of electric vehicles, together with the basic theories and methods of integrated transmission control of electric vehicles. The concepts of "power system" and "power transmission system" appear in this book, and their connotations need to be explained here. The so-called "powertrain" includes three assemblies: drive motor, controller, and power converter. The 'power transmission system' consists of components such as the drive motor, gearbox, and differential.

The book introduces two concepts: the "integrated" drive system for electric vehicles and the "integrated" drive system for electric vehicles. The so-called "integrated" drive system for electric vehicles refers to the integrated electric drive system (IEDS), which assembles the electric motor, gear transmission device, and drive axle together to reduce redundant components in traditional automotive power transmission systems, forming an integrated drive component that completes the power transmission system of electric vehicles for starting, driving, and braking. The highly "integrated" electric vehicle power system constitutes a highly integrated electric drive system (HIEDS), which integrates the controller, power converter, and cooling device of the motor drive system into the integrated power transmission system. By using the reasonable matching technology between the drive motor and the transmission system, the optimal control of the electric vehicle is achieved, making the function of the drive transmission system more excellent and the structure more compact.
