Abstract: A method for estimation of a vehicle tire force includes: receiving, by a controller of a vehicle, a measured vehicle acceleration of the vehicle; receiving, by the controller, a measured wheel speed and a measured yaw rate of the vehicle; forming, by the controller, inertia matrices based on an inertia of rotating components of the vehicle; calculating torques at corners of the vehicle using the inertia matrices; estimating tire forces of the vehicle based on the measured vehicle acceleration, the measured wheel speed, and the inertia matrices; and controlling, by the controller, the vehicle, based on the plurality of estimated longitudinal and lateral tire forces.

Abstract: A vehicle, and a method and system for operating the vehicle. The system includes a processor. The processor receives a driver input at the vehicle, determines a current lateral force on a tire of the vehicle for the driver input, determines a desired yaw rate and lateral velocity for the vehicle based on the current lateral force on the tire that operates the vehicle at a maximum yaw moment, and operates the vehicle at the desired yaw rate and lateral velocity.

Abstract: A method for dynamically determining a mass of a vehicle including a propulsion system coupled to a drive wheel is described, and includes monitoring vehicle operating conditions, executing an event-based estimation method based upon the vehicle operating conditions to determine a first vehicle mass state, and executing a recursive estimation method based upon the vehicle operating conditions to determine a second vehicle mass state. A final vehicle mass is determined based upon the first and second vehicle mass states.

Abstract: A vehicle, system and a method of driving a performance vehicle. The system includes a sensor for detecting a value of driver input to the vehicle, and a processor. The processor is configured to compare the value of the driver input to a threshold value for the driver input, switch to a performance mode operation for the vehicle when the value of the driver input is greater than the threshold value, generate a command at the vehicle based on the value of the driver input using a performance model of the vehicle activated in the performance mode, and activate a performance actuator of the vehicle to generate a dynamic parameter at the vehicle from the command.
