Abstract: A vehicle braking control system includes a vehicle microphone, two front wheels and two rear wheels of a vehicle, two front brakes and two rear brakes, and an electronic brake pressure control module configured to selectively control an amount of brake pressure applied to the front brakes and the rear brakes. The vehicle control module is configured to detect, via the at least one vehicle microphone, a brake noise value in response to brake pressure applied to the front brakes and the rear brakes, determine whether the brake noise value exceeds a specified brake noise threshold, identify which of the front brakes and the rear brakes are generating a greater noise value in response to the brake noise value exceeding the specified brake noise threshold, and reduce brake pressure applied to the identified one of the front brakes and the rear brakes.

IPC: A61G3/06
Abstract: A cargo lift system for a vehicle includes a frame system, a deck system, and a cargo hook. The frame system is configured to be attached to the vehicle. The deck system includes a deck frame having a plurality of deck frame segments. The deck system is operable to translate along the frame system in (i) a first deployment mode where the deck frame segments cooperate to define a rigid support platform and (ii) a second deployment mode where the deck frame segments articulate to a lift position adjacent to a ground surface associated with the vehicle The cargo hook is attached to the deck system and operable to move between an extended state and a retracted state.

Abstract: Methods and systems are provided for controlling braking to avoid groan noise in a braking system. The system has a brake actuator configured to apply a friction force to a moving member, a conduit system coupled with the brake actuator, an inlet valve in the conduit system configured to control fluid pressure delivered to the brake actuator, and an outlet valve in the conduit system configured to control fluid pressure released from the brake actuator. The system includes a controller to monitor for an upper target pressure condition in the braking system, wherein the upper target pressure condition is associated with a noise zone; and operate, when the upper target pressure is detected and in a noise zone avoidance mode, the inlet valve and the outlet valve to avoid brake pressures that generate a brake noise from the friction force.
