An electronic parking brake system includes an electronic parking brake, including an electric motor, and a controller configured to control the electric motor to engage the electronic parking brake, and when a vehicle motion detection signal is received from a black box through a controller area network (CAN) bus in a state where an ignition is turned off and the electronic parking brake is engaged, the controller is configured to re-engage the electronic parking brake.

An electronic parking brake system includes an electronic parking brake (EPB) including a pair of brake pads disposed on both sides of a brake disc rotating with a rear wheel of a vehicle, a piston provided to press the pair of brake pads, a nut member provided to press the piston, a spindle member provided to move the nut member, and an electric motor configured to rotate the spindle member; a wheel speed sensor configured to detect a wheel speed of the rear wheel; a G sensor configured to detect a longitudinal acceleration of the vehicle; an accelerator pedal sensor configured to detect an operation of an accelerator pedal of the vehicle; an EPB switch configured to receive a parking apply command or a parking release command from a driver; and a controller configured to control the electric motor, wherein the controller is configured to determine whether a residual clamping force is present in the EPB based on a rear wheel speed or the longitudinal acceleration at a time of departure of the vehicle after parking is released, and when the residual clamping force is present, release the residual clamping force through an additional parking release control.

A control system may include a modulator device that may receive a control signal for changing a traction operation or a braking operation of a vehicle system formed from one or more vehicles. The modulator device may generate an electric modulator signal based on the control signal and may control an actuator using the modulator signal to create an acoustic signal for propagation within a conduit extending along the vehicle system. The system also may include a transducer device that may detect the acoustic signal propagated in the conduit and generate an electric transducer signal based on the acoustic signal. The system may include a demodulator device that may control one or more of a traction device or a braking device to implement the control signal based on the transducer signal that is received.

The present disclosure relates to a resource allocation procedure for allocating time-frequency radio resources by a scheduler in a mobile communication system. A plurality of numerology schemes are defined, each partitioning a plurality of radio resources of the mobile communication system into resource scheduling units in a different manner. A reference resource set is defined per numerology scheme, each being associated to a set of radio resources usable for being allocated according to the respective numerology scheme. The reference resource set of at least one numerology scheme overlaps with the reference resource set of at least another numerology scheme in the frequency and/or time domain. The resource allocation procedure is performed for allocating radio resources to one or more user terminals according to the numerology schemes. The resource allocation procedure is performed for each numerology scheme based on a scheduling time interval defined for the respective numerology scheme.

This helically toothed belt power transmitting device (1) has: a toothed belt (10) having a plurality of teeth (12) tilted relative to the width direction of the belt; a drive pulley; and a driven pulley.
