Certain driver-assist features of a vehicle require incredibly precise longitudinal control of the vehicle. Achieving the precise control requires up-to-date knowledge of performance parameters of a brake system of the vehicle, which may vary extensively based on a wide set of influences outside the control of the brake system. The present disclosure proposes techniques to determine these parameters, for example, by stopping the vehicle early in maneuvering in order to study the brake performance, so that precise longitudinal control of the vehicle may be realized.

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 computer includes a processor and a memory storing instructions executable by the processor to determine at least one of a vehicle pitch or a longitudinal center of gravity from data measured while deactivating a first brake for a first axle and applying a second brake for a second axle, and operate the vehicle based on the at least one of vehicle pitch or longitudinal center of gravity. The instructions may further include to determine a vehicle weight from the data, and operate the vehicle based on the vehicle weight.

A vehicle includes a user-actuatable switch and a controller. When the switch is actuated, the controller is adapted to effect a regenerative braking command to actuate a regenerative brake system when a vehicle speed is above a threshold speed, and to effect a parking brake command to actuate an electric park brake when the vehicle speed is less than or equal to the threshold speed.

Vehicles and methods are disclosed for enabling vehicle occupants to maximize their time inside a vehicle during a remote parking operation, so as to limit exposure to adverse weather. An example vehicle includes a door, a sensor, and a processor. The processor is configured to determine a minimum open door angle for an occupant to exit, determine a vehicle path for execution of a remote parking operation, and, responsive to determining via the sensor during execution of the remote parking operation that the door is prevented from opening to the minimum door angle, pause execution of the remote parking operation.

This travel control device includes: a road determining unit which determines whether a road including a downward slope along which a vehicle is traveling includes a first curved road and a second curved road; and a travel control unit which, if the road determining unit has determined that the road contains the first curved road and the second curved road, causes the vehicle, when being caused to travel in such a way as to maintain a target speed, to decelerate at a curved road entry side of the first curved road and to coast from a curved road exit side of the first curved road, such that the vehicle can pass through the first curved road.

When an ON operation of an electric parking brake apparatus is performed when a vehicle is moving, a vehicle brake control apparatus executes an EPB stop process in order to stop the vehicle by braking force generated by a hydraulic brake apparatus. If a hydraulic brake malfunction wheel, at which the hydraulic brake apparatus cannot generate braking force properly, is detected during a time period from the beginning of the EPB stop process to the stop of said vehicle, the vehicle brake control apparatus makes the hydraulic brake apparatus stop generating braking force at wheels including the hydraulic brake malfunction wheel. Meanwhile, the vehicle brake control apparatus makes the electric parking brake apparatus start generating braking force at a rear wheel. Subsequently, the vehicle brake control apparatus makes the electric parking brake apparatus start generating braking force to the other rear wheel.

An intelligent ultrasonic system may include: a camera sensor unit configured to take an image of a road ahead of a driving vehicle; an ultrasonic signal input unit configured to receive an ultrasonic signal sensed through one or more ultrasonic sensors mounted on the vehicle; a feature extraction unit configured to extract a feature of the received ultrasonic signal; a data collision unit configured to collect one or more data related to a surrounding situation of the road on which the vehicle is driven; and a control unit configured to divide the surrounding situation into two or more classes based on the one or more data collected through the data collection unit, and change or reset an existing parameter to a parameter corresponding to any one class of the classes when the surrounding situation corresponds to the one class or is changed to the one class.

Provided are a vehicle, an electronic parking brake system and a control method thereof. The control method includes: controlling, when the electronic parking brake system is started, an electronic parking clamping force to be equal to a first preset value to perform parking braking on the vehicle; detecting the electronic parking clamping force and a current state of the vehicle; and when detecting that the vehicle moves, adjusting the electronic parking clamping force according to a magnitude relationship between the electronic parking clamping force and the first preset value to perform the parking braking on the vehicle again.

Disclosed are an EPB compatible with an autohold function, a starting method and a vehicle. According to the EPB, during starting, by converting the vehicle from a brake state where the EPB acts into a brake state where an autohold function acts and enabling the vehicle to start from the brake state where the autohold function acts, the vehicle is started stably, the starting noise of the vehicle is reduced and the driving experience is improved.
