Abstract
Disclosed is a number of variations that may include a method, system, or computer product useful in determining an intended yaw or yaw rate that a driver desires using a model, comparing the yaw or yaw rate with the actual vehicle yaw or yaw rate to determining a yaw error or yaw rate error, using the yaw error or yaw rate error in a model predictive control to determine the brake pressure required to minimize or reduced to zero the yaw error or the yaw rate error.
Claims15
A method comprising:
- determining an intended yaw or yaw rate that a driver desires using a model;
- comparing the intended yaw or yaw rate with the actual vehicle yaw or yaw rate to determine a yaw error or yaw rate error;
- using the determined yaw error or yaw rate error in a model predictive control module to determine the brake pressure to minimize or reduced to zero the yaw error or the yaw rate error.
A computer readable medium comprising non-transitory memory operable for machine instructions that are to be executed by an electronic processor, the instructions when executed by the electronic processor implement the following functions comprising:
- determining an intended yaw or yaw rate that a driver desires using a model;
- comparing the intended yaw or yaw rate with the actual vehicle yaw or yaw rate to determine a yaw error or yaw rate error;
- using the determined yaw error or yaw rate error in a model predictive control module to determine the brake pressure to minimize or reduced to zero the yaw error or the yaw rate error.
A system comprising:
- a predictive model control module, wherein the model predictive control model includes non-transitory memory with instruction stored thereon and executable by an electronic processor to carryout the acts of:
- receiving vehicle data and determining from the data an intended yaw or yaw rate that a driver desires using a model;
- comparing the intended yaw or yaw rate with the actual vehicle yaw or yaw rate to determine a yaw error or yaw rate error;
- using the determined yaw error or yaw rate error to determine the brake pressure to minimize or reduced to zero the yaw error or the yaw rate error.
