Abstract: A method for downforce control includes receiving vehicle inputs. The method includes determining a first normal-force request at the front axle and a second normal-force request at the rear axle using the purality of vehicle inputs and a prediction model. The prediction model is a combined state space model that integrates a half-car state space model and an actuator state space model, the half-car state space model is developed using a half-car model, and the actuator state space model is developed using a neural network model. The method further includes determining a first position of the first aerodynamic body relative to the vehicle body and a second position of the second aerodynamic body relative to the vehicle body based on the first normal-force request and the second normal-force request, respectively.

Abstract: A fault remediation system for a vehicle includes one or more controllers in electronic communication with one or more consumed interfaces and one or more provided interfaces. The one or more controllers execute instructions to receive, from the one or more consumed interfaces, a consumed signal and perform fault detection upon the consumed signal to determine the presence of an active fault within the consumed signal. In response to detecting an active fault with the consumed signal, the one or more controllers select a remediation state from a group of two or more prospective remediation states based on a significance analysis of the consumed signal. The one or more controllers evaluate a relevant subfunction that corresponds to the consumed signal that the remediation state addresses for the presence of remediation tolerance and generates arbitration instructions based on the remediation tolerance.

Abstract: A method for powerhop identification and mitigation includes receiving sensor data of a vehicle, such as wheel speed; determining a wheel jerk characteristics of the vehicle based on the wheel speed; determining a ride height of the vehicle; determining whether the vehicle is experiencing powerhop based on the wheel jerk characteristics and the ride height of the vehicle; and in response to determining that the vehicle is experiencing powerhop, adjusting a torque of the vehicle to mitigate the powerhop.

Abstract: A system to map control system configurations for vehicle torque actuators includes a control unit of a vehicle. A first torque actuator of a first power unit delivers torque to rear wheels of the vehicle, and a second torque actuator of a second power unit delivers torque to front wheels of the vehicle. Multiple input items are received by the control unit, including: multiple configurations; one or more operating points; multiple configuration classifications including: a torque constraint; a torque reference; and an enabling condition; and identification of one or more priority assignments. The priority assignments are applied to the configurations, the operating points and the configuration classifications to determine a control action as sensed vehicle operating conditions change. Individual ones of the configurations are mapped to a normalized torque split ratio.

Abstract: A system comprises a computer including a processor and a memory. The memory includes instructions such that the processor is programmed to: determine an occurrence of intentional drift event, and in response to determining the occurrence of the intentional drift event, determine a front torque target and a rear torque target.
