    Abstract: A shield assembly is employed for a friction brake used to decelerate a road wheel of a vehicle. The vehicle has a body with a first body end configured to face an incident ambient airflow, a second body end opposite of the first body end, and an underbody section spanning a distance between the first and second ends. The shield assembly includes a first shield component arranged proximate the brake and rotationally fixed relative to the vehicle body. The shield assembly also includes a second shield component operatively connected to the first shield component for shifting relative thereto. The shield assembly additionally includes an actuator employing a shape memory alloy element to shift the second shield component relative to the first shield component in response to a temperature of the brake to thereby direct at least a portion of the airflow to the brake and control temperature thereof.

    Abstract: Systems and methods for reducing transient brake caliper drag in a motor vehicle are provided. The motor vehicle, for example, may include, but is not limited to, an axle, a rotor coupled to the axle, a brake caliper comprising a brake pad configured to engage the rotor, a brake pedal assembly communicatively coupled to the brake caliper, the brake pedal assembly configured to receive user input directing the brake pad to apply a force to the rotor and user input directing the brake pad to disengage the rotor, and a processor coupled to the brake caliper, wherein the processor is configured to determine, after the brake pedal assembly receives user input directing the brake pad to disengage the rotor, the force applied to the rotor, and command the brake caliper to retract the brake pad away from the rotor when the determined force exceeds a predetermined threshold.

    Abstract: A vehicle is disclosed. The vehicle includes a body. The body includes a forward end and a rearward end spaced from each other along a longitudinal axis. The forward end of the body defines an opening for allowing airflow into the body. The vehicle also includes a venturi brake duct assembly positioned relative to the opening to receive the airflow from the opening and to guide the airflow to a brake device for cooling the brake device.

    Abstract: An automotive vehicle includes a body having a passenger compartment and a pedal assembly disposed within the passenger compartment. The pedal assembly includes a brake pedal emulator housing and at least one pedal interface coupled to the housing. The vehicle also includes an actuator operably coupled to the brake pedal emulator housing. The actuator is configured to selectively move the housing and the pedal interface between a first position and a second position with respect to the passenger compartment. The vehicle further includes at least one controller in communication with the actuator. The controller is configured to, in response to satisfaction of a first operating condition, control the actuator to move the housing and the pedal interface to the first position, and, in response to satisfaction of a second operating condition, control the actuator to move the housing and the pedal interface to the second position.
