Electric equipment for a vehicle with an electropneumatic service brake device, in which at least one pneumatic brake control pressure is immediately and directly controlled to the electromagnetic backup valve, which is still being closed by a current, of at least one pressure regulating module in response to an assistance brake request signal regardless of a defect of an electric service brake circuit. For a failure of the electric service brake circuit, the electromagnetic backup valve, which is then in the currentless state, of the at least one pressure regulating module is automatically opened, and the brake pressure is immediately formed in the pressure regulating module based on the at least one pneumatic brake control pressure already present in the pressure regulating module. Thus, the reaction time of a pneumatic redundancy of the electropneumatic service brake device in response to electric defects is reduced.

Electropneumatic equipment for a vehicle with an autonomous brake circuit supplied with backup pressure as a precaution

A method for operating an anti-lock braking system control unit for a highly automated vehicle with at least one steering axle, including: reading in an activation signal, which represents an activated steering brake function of the vehicle and/or a deactivated electrically actuatable steering function of the vehicle; and transmitting a control signal using the activation signal, wherein the control signal is for setting a control mode for controlling an ABS function of the anti-lock braking system control unit for at least the steering axle of the vehicle. Also described are a related apparatus, anti-lock braking system control unit, and computer readable medium.

A method for defining at least one characteristic curve of a pressure-medium-actuated brake system of a vehicle, the curve representing a relationship between a brake pressure and a brake demand, and for operating a pressure-actuated brake system of a vehicle, in which at least one brake cylinder can be supplied with a pressurized medium under a braking pressure, and in which the braking pressure is formed based on at least one such characteristic curve, and to a pressure-actuated brake system of a vehicle in which at least one brake cylinder can be supplied with a pressurized medium under a braking pressure.

A method for defining at least one characteristic curve which, in a pressure-actuated brake system of a vehicle, represents a relationship between a brake pressure and a brake demand), and for operating a pressure-actuated brake system of a vehicle, in which at least one brake cylinder can be supplied with a pressurized medium under a brake pressure, and in which the brake pressure is formed based on at least one such characteristic curve, and to a pressure-actuated brake system of a vehicle in which at least one brake cylinder can be supplied with a pressurized medium under a brake pressure.

A steering control system for a commercial vehicle having braking and steering systems. The braking system brakes dissymetrically side wheels of the vehicle. The steering system steers the vehicle based on a steering signal. The steering control system includes selection and control modules. The selection module switches between first and second steering modes. The first mode indicates steering of the vehicle by turning vehicle wheels. The second mode indicates steering of the vehicle by generating a braking signal for at least one wheel providing a yaw moment applied to the vehicle. The control module generates the first signal indicating a steering demand in the first mode and a second signal indicating a steering demand in the second mode. The control module provides the first signal to the steering system and the second signal to the braking system to brake the vehicle dissymetrically to steer the vehicle with the yaw moment.

Steering control system and a method for controlling steering

A method for preventing a rollover of a vehicle or a tractor-trailer combination in curves, by counteracting a rollover risk of the vehicle by independent regulating interventions, performed without action by a vehicle driver, in a regulation system that actuates the drive and/or the brakes of the vehicle, the method including: capturing the current driving situation and the current load of the vehicle or the tractor-trailer combination as to the current driving position of the vehicle or the tractor-trailer combination, ascertaining a maximum admissible transverse acceleration at the current driving position, at which maximum admissible transverse acceleration the vehicle or the tractor-trailer combination just does not roll over, as to the current driving situation and the current load of the vehicle or the tractor-trailer combination. Also described is a related apparatus for preventing a rollover of a vehicle or a tractor-trailer combination in curves.
