Vehicle braking control device
11511714 · 2022-11-29 · ·

This vehicle braking control device executes automatic braking control to adjust a braking torque on the basis of a vehicle target deceleration value corresponding to a distance between the vehicle and an object in front of the vehicle, and executes anti-skid control to suppress excessive wheel slip by adjusting the braking torque on the basis of a wheel speed. The braking control device calculates an actual deceleration value corresponding to the target deceleration value, and executes feedback control on the basis of the target deceleration value and the actual deceleration value such that the actual deceleration value approaches the target deceleration value. The configuration is such that a control gain of the feedback control is reduced when anti-skid control is executed. Further, the configuration may be such that execution of feedback control is prohibited when anti-skid control is executed.

BRAKE SYSTEM FOR A MOTOR VEHICLE

A brake system for a motor vehicle has electromechanical wheel brakes, a brake operating unit and a central brake control unit. The wheel brakes each have a local brake control unit. The central brake control unit is connected to the brake operating unit and the local brake control units via a first data connection. The brake operating unit is connected to the local brake control unit of at least one wheel brake via a second data connection. In a normal operating mode the central brake control unit determines at least one brake demand from first operating information, received via the first data connection and transmits control signals corresponding to the brake demand to the local brake control units. In a fallback operating mode the local brake control units actuate the respective wheel brakes basis on second operating information, received via the second data connection.

Dynamic resource allocation among different OFDM numerology schemes

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.
