The disclosure relates to a vehicle system for a vehicle, in particular a commercial vehicle, that includes an electronically controllable pneumatic braking system, and an electronically controllable steering device. The electronically controllable pneumatic braking system has a redundant control unit, which controls the brake circuits in the event of a failure of an electronic stability control of the braking system during travel. In the event of the failure of the electronic stability control during travel, the redundant control unit performs axle-wise control of the front axle with a front axle redundancy brake pressure and/or of the rear axle with a rear axle redundancy brake pressure and the electronically controllable steering device carries out laterally stabilizing steering interventions in order to keep the vehicle in a tolerance corridor of a predefined target trajectory of the vehicle. The disclosure also relates to a vehicle and a method.

Vehicle system having an esc-fault-tolerant braking system

A method for displaying an environment of a vehicle on a display includes: recording the environment with at least two cameras, each having a different field of view, wherein fields of view of adjacent cameras overlap; creating a panoramic image from at least two images taken by differing cameras, the images being projected into a reference plane for creating the panoramic image; ascertaining depth information pertaining to an object in the environment by triangulation from at least two differing individual images taken by the same camera; and generating an overlay structure as a function of the ascertained depth information, the overlay structure having been uniquely assigned to an imaged object; and, representing the created panoramic image, containing the at least one object, and the at least one generated overlay structure on the display such that the overlay structure is displayed on, and/or adjacent to, the assigned object.

Method for displaying the surroundings of a vehicle on a display device, processing unit and vehicle

A method for determining a coefficient-of-friction, the method including braking a first wheel of a vehicle such that a slip between the first wheel and a roadway is less than a slip between a second wheel of the vehicle and the roadway, and determining a coefficient-of-friction between the first wheel and the roadway based on the behavior of the first wheel during the braking. The method optionally including hazard braking the vehicle.

Coefficient-of-friction estimator

A brake pressure modulator () of an electronic braking system of a utility vehicle includes pressure control circuits () respectively associated with a braking circuit of a vehicle axle, each pressure control circuit () comprises a compressed air supply system (), at least one redundancy control pressure path (), at least one ventilation path () and a common electronic control unit (). Said pressure control circuits () can be controlled independently from each other by the electronic control unit (). Each pressure control circuit () has an independent ventilation path () and at least one of the pressure control circuits () has an independent redundancy control pressure path () and at least one other of the pressure control circuits () comprises a device () for forced venting in the event of a failure by means of the associated ventilation path ().

Brake pressure modulator of an electronic braking system of a utility vehicle

A vehicle braking unit comprises an operating braking pressure inlet which receives an inlet braking pressure built up by a braking cylinder, and at least one operating brake pressure outlet at which an outlet braking pressure is provided for an operating brake modulator, which is upstream of the operating brake and provides anti-lock functionality. At least one connecting channel hydraulically connects the operating brake pressure inlet to the outlet. Brake fluid is supplied from a storage unit through the brake cylinder, the connecting channel and the operating brake modulator. The braking unit has a brake fluid inlet, through which the brake fluid is received from the storage unit, a brake fluid pump, by which the brake fluid is suctioned through the brake fluid inlet and a supply pressure is built up, and a valve unit that controls the outlet braking pressure and/or a parking brake release pressure by the supply pressure.

Vehicle braking unit and method

A braking device for a vehicle comprises a main brake cylinder, which provides, in response to the actuation thereof, an operating brake pressure in at least one operating brake circuit for the actuation of an operating brake. A hydraulic fluid pressure intake is connected to a hydraulic circuit, which contains a hydraulic fluid having a built-up hydraulic circuit pressure. Through the hydraulic fluid pressure intake, the hydraulic fluid is provided at the hydraulic circuit pressure. The braking device further comprises a valve device, which actively controls a main brake cylinder actuation pressure and/or a parking brake release pressure by means of the hydraulic fluid that is provided. The main brake cylinder is actuated by means of the main brake cylinder actuation pressure for an active brake engagement. Alternatively or additionally, a parking brake is hydraulically released by means of the parking brake release pressure.
