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 abstract describes a method for controlling torque vectoring in an xEV (electric vehicle) by detecting vehicle speed information, estimating the vehicle speed based on the detected information, setting the state of the xEV based on the estimated speed, and determining if there is an intervention request. If the intervention request is rejected, the method detects the steering angle of the xEV and determines if it is within a predetermined range. If it is, the xEV is considered to be in a slip state and the vehicle speed is reset through the output of a torque vectoring motor.
- Detect vehicle speed information using speed sensors mounted in the xEV
- Estimate the vehicle speed based on the detected information
- Set the state of the xEV based on the estimated speed
- Determine if there is an intervention request based on the set state of the xEV
- Detect the steering angle of the xEV when the intervention request is rejected
- Determine if the detected steering angle is within a predetermined range
- If the steering angle is within the range, consider the xEV to be in a slip state
- Reset the vehicle speed through the output of a torque vectoring motor

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.
