Abstract: Technical solutions are described for autonomously monitoring health of a vehicle, such as a car, a truck and so on. An example computer-implemented method includes receiving sensor data of the vehicle. For example, the sensor data includes vibration data and microphone data. The vibration data measures vibration experienced by an occupant of the vehicle. The microphone data measures noises experienced by the occupant, including noises emanated by the vehicle. The method further includes accessing a predetermined performance data of the vehicle and determining a difference in the received sensor data and the predetermined performance data. The method further includes transmitting a notification of condition of the vehicle in response to the difference surpassing a predetermined threshold.

Abstract: A vehicle employing an active aerodynamic control system is described. A method for controlling the active aerodynamic control system includes determining a target acceleration downforce associated with an acceleration request and vehicle speed, determining a target braking downforce associated with a braking request and vehicle speed, and determining a target cornering downforce associated with a cornering request and vehicle speed. A maximum downforce request and a second greatest downforce request of the target acceleration downforce, the target braking downforce, and the target cornering downforce are determined. A preferred front/rear distribution of downforce is determined based upon the maximum downforce request and the second greatest downforce request. The active aerodynamic control system is controlled based upon the preferred front/rear distribution of downforce and the maximum downforce request.

Abstract: A system is disclosed for controlling an incident ambient airflow in a vehicle. The vehicle includes a vehicle body with a first vehicle body end configured to face the incident ambient airflow when the vehicle is in motion relative to a road surface. The system includes a duct providing a conduit for the incident airflow into the vehicle body. The system also includes a shutter assembly configured to control the airflow through the duct and thereby regulate a downforce acting on the first vehicle body end. The shutter assembly may include an adjustable louver, a mechanism configured to select the position for the louver between and inclusive of fully opened and fully closed, and a controller configured to regulate the mechanism. The vehicle may also have a heat-absorbing subassembly, and the duct can provide a conduit for the incident airflow to the heat-absorbing subassembly for cooling thereof.

Abstract: A system and method for generating steering commands to cancel out unwanted steering moments is disclosed. The method includes determining, by a controller of a vehicle, an amount of suspension displacement that is caused as a result of driving the vehicle on an uneven road. The suspension displacement induces an unwanted steering moment. The method also includes determining a steering angle command based at least on the amount of suspension displacement. The method also includes performing the steering angle command. Performing the steering angle command cancels out the unwanted steering moment.

Abstract: A splitter system for a vehicle having a vehicle body including a first vehicle body end configured to face oncoming ambient airflow when the vehicle is in motion includes first and second splitter portions. The first splitter portion is configured to be fixed to the vehicle body. The second splitter portion is mounted to the first splitter portion. The first and second splitter portions together are configured to generate an aerodynamic downforce on the vehicle body when the vehicle is in motion. The splitter system also includes a mechanism arranged between the first and second splitter portions. The mechanism is configured to vary position of the second splitter portion relative to the first splitter portion to thereby control movement of the oncoming ambient airflow relative to the vehicle body and vary a magnitude of the aerodynamic downforce.

Abstract: An exemplary method to detect a wear condition of a vehicle damper includes the steps of receiving tire condition data from a vehicle sensor, calculating an amplitude of the tire condition data as a function of frequency, monitoring the amplitude of the tire condition data within a predetermined frequency range, determining whether the amplitude of the tire condition data is greater than a predetermined threshold and, if the amplitude is greater than the predetermined threshold, increasing an oscillation count by one, and comparing the oscillation count to a predetermined count threshold.

Abstract: An adjustable aerodynamic assembly includes a support structure and a blocking member supported by the support structure. The blocking member is movable between an extended position in which the blocking member is disposed transverse to the support structure to interact with an airflow and a retracted position in which the blocking member retracts to minimize interaction with the airflow. The adjustable aerodynamic assembly also includes an actuator coupled to the blocking member and configured to move the blocking member to the extended and retracted positions, and a detection member coupled to the blocking member and configured to determine whether a surface of the blocking member is detected.A method of monitoring the adjustable aerodynamic assembly includes determining whether the surface of the blocking member is detected via the detection member. The method also includes selectively activating the actuator to move the blocking member to the extended and retracted positions.
