Abstract: A product may include a steering tube that may have a first component, and a second component. A hinge may be connected to enable the first and second components to fold relative to one another so that the steering tube is foldable. A latch may secure the first and second components in an unfolded position. The first and second components may be locked in a folded position. The latch may include a lever that has a latch hook. The first and second components may be secured through engagement of the latch hook with a striker.

Abstract: A method for performing a data validity assessment for a brake pad wear estimation includes providing an electric park brake assembly including a motor and a battery management sensor, receiving motor current data from the motor of the electric park brake assembly, receiving battery current data from the battery management sensor, determining a margin of current from the motor current data and the battery current data, receiving historical motor position data and instant motor position data of the motor, calculating the brake pad wear estimation using the motor current data, comparing the historical motor position data and the instant motor position data against an expected range of motor positions, determining an electromagnetic interference level from the margin of current, the historical and instant motor position data, and the calculated brake pad wear estimation, and discarding the motor current data when the electromagnetic interference level is above a predetermined threshold.

Abstract: A product may include a pair of handles that may be foldable. A wedge may be engaged between the pair of handles and may lock the pair of handles in a first position. A release mechanism may be connected to the wedge. Operation of the release mechanism may move the wedge to disengage from and to unlock the handles and may enable moving the pair of handles to a folded position.

Abstract: An exemplary method for performing a brake pad life determination includes providing a brake assembly, including a brake pad position sensor, providing a control system comprising a controller electronically connected to the brake assembly, receiving sensor position data from the brake pad position sensor, determining whether the sensor position data satisfies a first acceptance criterion, if the sensor position data satisfies the first acceptance criterion, performing statistical analysis of the sensor position data to determine a standard deviation and a mean of the sensor position data, determining whether the sensor position data satisfies a second acceptance criterion, and if the sensor position data satisfies the second acceptance criterion, determining a brake pad life estimate.
