A vehicle includes a powerplant, such as an engine, configured to power front and rear wheels, and a controller. The controller is programmed to, brake a first of the front wheels and a first of the rear wheels while powering a second of the front wheels and a second of the rear wheels to warm those tires, and subsequently brake the second front wheel and the second rear wheel while powering the first front wheel and the first rear wheel to warm those tires.

A system and method for disabling the travel of a vacuum truck is provided in which a vacuum boom initiates an interlock signal when positioned back into a travel cradle. An additional positional tank bed further includes an interlock signal when the bed is in a secured in a travel position. The vacuum truck is prevented from having its brakes released or prevented from being put into a travel gear if either the truck bed or vacuum boom are not in secure travel positions. The present system and method utilize pneumatic operating signals available from the vehicles power take off and blower mode switch.

A method for operating a parking brake system includes establishing a parking brake request for a first automated parking brake constructed on a first wheel located on a first side of an axle of a motor vehicle, producing a braking force at the first wheel by activating, in response to the establishing of the parking brake request, the first automated parking brake, and activating a compensation device connecting the first wheel and a second wheel located on a second side of the axle to apply a braking force to the second wheel via the first wheel.

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.

A method for monitoring the release behavior of an electromechanical wheel brake of a vehicle, the wheel brake having at least one electrically controllable force actuator configured to apply a brake-application force to friction partners of the wheel brake. comprises activating the force actuator in accordance with a defined control pattern which is dependent on a present operating state of the wheel brake, a present operating state of further wheel brakes of the vehicle, and/or a present operating state of the vehicle. The activation of the force actuator is interrupted at a defined point in time. The operating parameters of the wheel brake are monitored for a defined period of time after the interruption of the activation. The release behavior of the wheel brake is determined by ascertaining a reaction of the force actuator to the interruption of the activation on the basis of the ascertained operating parameters.

An emergency braking system according to an embodiment of the present invention, which performs emergency braking and brake release according to a position of an object detected while a vehicle moves backward, comprises a processor deriving a position of the object by processing data detected by a sensor, and a controller controlling emergency braking and brake release using the derived position of the object, wherein the controller releases a brake through different operation according to an area in which the position of the object is included after emergency braking of a plurality of areas into which a detecting area of the sensor is divided.

A method for controlling a vehicle includes monitoring the vehicle speed for a first threshold in conjunction with a driver request for negative torque, after which the method comprises increasing a friction braking ratio. The method further comprises monitoring the speed of the vehicle for a second threshold, wherein the second threshold is lower than the first, after which the method comprises solely using the friction braking for braking holding torque.

A vehicle includes friction brakes, an electronic park brake system, and controllers. The controllers, responsive to the vehicle coming to a stop, and the vehicle being on plug, a driver door of the vehicle being open, or a driver seatbelt being unbuckled, issue a standstill friction brake request for the friction brakes and an electronic park brake request for the electronic park brake system. The controllers also, responsive to engagement of the electronic park brake system, discontinue the issue of the standstill friction brake request.
