Abstract
A number of variations may include a method that may include modifying, in real-time, at least one brake or powertrain torque or force to one or more roadwheels of a vehicle to increase lateral stability during Brake-to-Steer functionality.
Claims28
A product comprising a non-transitory computer readable medium having instructions thereon executable by an electronic processor to implement functionality comprising:
- receiving vehicle dynamics data input;
- receiving or calculating one or more stability indicators and thresholds;
- using stability indicator duration and magnitude to determine when an instability event is occurring;
- when an instability event is occurring, using at least one of a first learned Mu estimate, current learned brake-to-steer modifications, or previously stored stability memory data to calculate a first brake-to-steer modification.
