METHOD AND APPARATUS FOR CONTROLLING TORQUE VECTORING OF xEV - A simplified explanation of the abstract

This abstract first appeared for US patent application 17984619 titled 'METHOD AND APPARATUS FOR CONTROLLING TORQUE VECTORING OF xEV

Simplified Explanation

The patent application describes a method for controlling torque vectoring in an xEV (electric vehicle) using speed sensors and steering angle detection. Here are the key points:

  • The method involves detecting vehicle speed information using speed sensors mounted in the xEV.
  • The detected vehicle speed information is used to estimate the vehicle speed of the xEV during driving.
  • Based on the estimated vehicle speed, the state of the xEV is set.
  • An intervention request is determined based on the set state of the xEV.
  • If the intervention request is rejected, the method detects the steering angle of the xEV.
  • If the detected steering angle is within a predetermined reference angle range, the xEV is determined to be in a first slip state where it slips in a longitudinal direction.
  • To reset the vehicle speed of the xEV, a torque vectoring (TV) motor mounted in the xEV is used to output torque.

Potential applications of this technology:

  • Electric vehicles (xEVs) can benefit from this method to improve torque vectoring control, enhancing their overall performance and handling.
  • Automotive manufacturers and suppliers can incorporate this method into their xEVs to provide better control and stability during driving.

Problems solved by this technology:

  • This method addresses the challenge of effectively controlling torque vectoring in xEVs, particularly in situations where intervention requests are rejected.
  • By detecting the steering angle and determining the slip state, the method helps reset the vehicle speed and maintain stability in the xEV.

Benefits of this technology:

  • Improved control: The method allows for more precise control of torque vectoring in xEVs, leading to enhanced handling and performance.
  • Increased stability: By resetting the vehicle speed and addressing slip states, the method helps maintain stability during driving, especially in challenging conditions.
  • Enhanced safety: The improved control and stability provided by this method contribute to safer driving experiences in xEVs.


Original Abstract Submitted

A method for controlling torque vectoring of an xEV includes detecting vehicle speed information using speed sensors mounted in the xEV, and estimating a vehicle speed of the xEV in driving based on the detected vehicle speed information, setting a state of the xEV based on the estimated vehicle speed, determining whether there is an intervention request based on the set state of the xEV, detecting a steering angle of the xEV when the intervention request is rejected, and when the detected steering angle of the xEV is within a predetermined reference angle range, determining the xEV as being in a first slip state in which the xEV slips in a longitudinal direction, and resetting the vehicle speed of the xEV through output of a torque vectoring (TV) motor mounted in the xEV.
