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.

A traction saddle disposed on a tractor for connection with a traction pin of a trailer, is provided. The traction saddle includes a base, a gear set, and a damper. A gear carrier of the gear set fixes planetary gears of the gear set, the planetary gears are meshed with an inner ring gear of the gear set, and the inner ring gear is fixed to the base. The gear carrier is used for fixing the traction pin to rotate with the traction pin. The planetary gears are meshed with a sun gear of the gear set to drive the sun gear to rotate, and the damper is connected to the sun gear to apply resistance. In addition, a traction pin, a tractor, a trailer, and a truck are also provided.

A vehicle combination comprising a tractor vehicle and a trailer vehicle, each vehicle including wheels on different sides of the vehicle and wheel brakes associated with the wheels. A method for controlling the vehicle combination includes determining a yaw rate difference between a yaw rate of the tractor vehicle and a yaw rate of the trailer vehicle; determining, on the basis of the yaw rate difference, that an orientation of one of the vehicles deviates from an intended travel direction of the vehicle combination; and activating a wheel brake of the vehicle on only one side of the vehicle in order to counter the orientation deviation of the vehicle relative to the intended travel direction.

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.

A dolly stabilizer is mounted onto a rear end of a trailer and has a stabilizer plate, a stabilizer pin, and a control box. The stabilizer plate is mounted to a chassis having at least one pair wheels. The stabilizer plate may comprise a plurality of mounting holes. It includes a dolly tongue stabilizer pin hole that receives the stabilizer pin. The stabilizer plate includes an internal piston that is selectively driven into a recess or opening in the stabilizer pin to straighten a position of a subsequent trailer or dolly relative to a preceding one. The control box includes a pneumatic input for receiving pressurized air and a pneumatic output to brakes on the dolly. A speed sensor may be coupled to the control box for allowing speed control of the dolly wheels. Electrical connections accept power for operating lights and other electrical devices on the dolly.

Systems and methods are described for monitoring movement of a trailer relative to the towing vehicle and providing driver-assistance information to the driver of the towing vehicle. The system determines a velocity vector for the host vehicle at a location near a rear of the host vehicle at a defined lateral distance from a trailer hitch installed on the host vehicle. The system also determines a velocity vector for the trailer at a corresponding location on the trailerthat is a location on the front of the trailer at approximately the same defined lateral distance from the trailer hitch. The system compares the velocity vector for the host vehicle to the velocity vector for the trailer and determines, based on the comparison, whether a jack-knife condition is likely to occur. If a jack-knife condition is likely to occur, the system generates a warning signal.

A trailer includes a battery and an axle or a tandem axle with wheels driven by way of electric motors. The battery supplies electricity to the electric motors during trailer travel, and a sensor detects forces on a coupling of the trailer in at least one of the following directions: longitudinal direction of the trailer and/or transverse direction of the trailer and/or perpendicular direction, and a controller controls the electric motors, so that a minimum and/or a maximum limit value is adhered to.

A trailer oscillation and stability control device including an accelerometer and an angular rate sensor. An oscillation detection discriminator detects oscillatory lateral trailer motion in response to trailer displacement data derived from inputs from the angular rate sensor and acceleration signals received from the accelerometer, and then generates corresponding oscillatory event data. A brake controller generates a braking control signal in response to oscillatory event data received from the oscillation detection discriminator.

Embodiments are presented herein for trailer sway detection and mitigation using a camera mirror system. In one embodiment, a vehicle controller is provided comprising: one or more processors; a non-transitory computer-readable medium; and program instructions stored on the non-transitory computer-readable medium. When executed by the one or more processors, the program instructions cause the one or more processors to: monitor images captured by at least one image capture device to detect sway of a trailer being towed by a tractor; and in response to detecting sway of the trailer, cause a braking system to apply a brake to attempt to reduce to the sway of the trailer.

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.
