Discussion Overview

The discussion revolves around the design of a steer-by-wire system, focusing on the calculation of motor torque and the selection of an appropriate Electronic Control Unit (ECU). Participants explore parameters relevant to the system's operation, including the role of data from the on-board data port and the types of motors needed for the application.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested
  • Homework-related

Main Points Raised

  • One participant inquires about a formula to calculate motor torque for a steer-by-wire system and seeks guidance on selecting a proper ECU.
  • Another participant suggests checking the parameters available via the on-board data port, implying this data could assist in determining torque.
  • There are repeated mentions of the need for clarity regarding the type of motor being referred to, whether it pertains to the car's engine or the steering system.
  • A participant expresses confusion about the parameters needed for the steer-by-wire system and indicates a lack of familiarity with the necessary components and simulation processes.
  • One participant mentions the need to select two DC motors: one for the steering reaction force actuator and another for the steering actuator, along with an ECU to control them.
  • There is a request for recommendations on resources or forums for further information, particularly from a participant who is not familiar with the US context.

Areas of Agreement / Disagreement

Participants express varying levels of understanding regarding the parameters and components necessary for the steer-by-wire system. There is no consensus on the best approach to selecting the ECU or calculating motor torque, indicating multiple competing views and unresolved questions.

Contextual Notes

Participants highlight limitations in their understanding of the system's requirements and the available data from the ECU. There is also uncertainty regarding the specific types of motors needed and the overall design process for the steer-by-wire system.

I plan to design a steer by wire system,is there a formula to caculate the motor torque?and how can i select a proper ECU.
regards.

Have you looked at what parameters are available via the on-board data port?

oh,i am sorry that i can't understand your implement exactly,i plan to do a steer by wire system include it's controller.I am also puzzled with the parameter.my purpose is realize the steer .

You asked about motor torque. Are you aware that a car's Engine Control Unit provides data that you can read and may help find torque? Have you looked at what data is available?

[edit] Reading your question again, it isn't clear to me what "motor" you are referring to...car or steering system...

My work is select two motors(most of them are dc motor).one is the Steering reaction force actuator.the other is Steering actuator .And select a ecu to control these two motors to realize the steer work.I'm not familiar these works and puzzled for the whole work,especially the simulation.
I'm not transform a car from mechanism to steer-by-wire.I am designing a simple model for a electric car.So, i can't get the available from the ECU.
I'm not familiar with the US,could you recommend me some information(the web or forum).
I'm very grateful for your help.
