The system includes: a sensor component configured to collect sensed information on an environment where a semitrailer is located; and a braking controller configured to determine whether there is a risk of collision for the semitrailer based on the sensed information, and if so, calculate a maximum adhesive force that can be provided by a road surface the semitrailer is currently on, determine a first braking pressure corresponding to each wheel based on the maximum adhesive force and axle load information, and transmit to a braking system a first braking instruction carrying the first braking pressure for each wheel.

An operating method for an electrified motor vehicle having an electric drive while being coupled to a towing vehicle by a connecting device in such a manner that the pulling forces and pushing forces between the vehicles are transmitted. The towing vehicle may communicate data to the motor vehicle used to control the motor vehicle to provide a controlled force exerted on the towing vehicle by the motor vehicle during towing. The controlled force exerted on the towing vehicle may vary based on the prevailing force direction between the vehicles, acceleration, and battery state of charge (SOC) of the motor vehicle. The controlled force may include a driving force or a braking force. The braking force may be provided by regenerative braking of the motor vehicle and/or by friction braking of the motor vehicle.

An electric system of a vehicle including an electronically controlled braking system. The electric system has a steering angle sensor unit, at least one control module, at least one first inertia sensor and an electronic braking system central control unit EBS ECU. The at least one control module is external to the steering angle sensor unit. The at least one control module is also external to the EBS ECU. At least one of the at least one control module has mounted within it one of the at least one first inertia sensor.

An electropneumatic brake system, for a commercial vehicle which is provided for pulling a trailer, includes at least one service brake circuit configured to activate service brake actuators, a parking brake circuit having parking brake actuators on at least one axle, a trailer brake circuit configured to provide a trailer brake pressure at a trailer brake pressure port, and a manually actuatable operating unit in a driver's cab. The manually actuatable operating unit has a first operating element and a second operating element. In the case of actuation of the first operating element when the vehicle is driving, the parking brake actuators are activated and a trailer brake pressure is output at the trailer brake pressure port. In the case of actuation of the second operating element when the vehicle is driving, only a trailer brake pressure is output.

Methods, apparatus, systems and articles of manufacture are disclosed for automatic calibration of electronic trailer brake gain. An example apparatus includes a trailer brake gain calibration module programmed to compare a calculated trailer brake torque to at least one of a first or second threshold, adjust a gain value based upon satisfaction of at least one of the first or second threshold, and apply a pressure to a trailer brake based on the gain value.

A system and method of controlling individual trailer brakes on a towed trailer supporting numerous fault tolerant behaviors including activating each operational brake when a brake is shorted. System operates in multiple modes where it operates with traditional brake controllers, operates in a degraded braking mode without a brake controller and in the preferred mode it retrieves vehicle information from tow vehicle and then communicates with a brake actuator controller over the trailer brake wire. When braking system includes wheel sensors traditional antilock releases are provided and unlike other braking systems this brake actuator controller can maintain wheel speeds below the trailer speed reducing or eliminating periodic wheel releases. System also diagnoses the mechanical operation of the trailer brakes including; identifying when brake adjustment is required, when brake friction surfaces are degrading, as well as diagnosing sensors, braking signals and brake actuator interfaces.

A method and device for stabilizing a tractor vehicle-trailer combination during travel, in which tractor vehicle and trailer are connected via at least one pivot joint, including: ascertaining a setpoint buckling angle for a driving-stable setpoint movement of the combination, and/or a setpoint buckling angle velocity for a driving-stable setpoint movement of the combination, between the combination or between two trailers; ascertaining an actual buckling angle for the effective actual movement of the combination, and/or an actual buckling angle velocity for the effective actual movement of the combination, between the tractor vehicle and trailer or between multiple trailers; ascertaining a deviation between the setpoint and actual buckling angles and/or between the setpoint and actual buckling angle velocities, and if the deviation exceeds a threshold value, generating a control signal to activate at least one vehicle component to control movement of the combination in a direction toward a driving-stable movement state.

An agricultural implement is provided. The agricultural implement includes a braking system configured to slow or stop the agricultural implement. The agricultural implement also includes a hitch configured to couple the agricultural implement to a towing vehicle. The agricultural implement further includes an electronic sensor disposed on the hitch and configured to sense tension and compression forces. The agricultural implement further includes a controller configured to automatically actuate or disengage the braking system in response to a signal indicating a presence of compression or tension forces from the electronic sensor.

Disclosed is a method for automatically controlling brakes in a trailer vehicle having antilock control, wherein wheel rotational speeds are continuously monitored and evaluated at wheels having antilock control. According to the method, lateral acceleration and longitudinal acceleration of the trailer vehicle are determined. If a predefined, critical lateral acceleration is exceeded, an automatic braking process occurs. A control unit and trailer vehicle are also disclosed in connection with the inventive method.
