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.

The present disclosure includes a system, method, and device related to controlling brakes of a towed vehicle. A brake controller system includes a brake controller that controls the brakes of a towed vehicle based on acceleration. The brake controller is in communication with a speed sensor. The speed sensor determines the speed of a towing vehicle or a towed vehicle. The brake controller automatically sets a gain or boost based on the speed and acceleration.

A trailer electronic braking system comprising a braking device capable of generating a braking force on a wheel on the trailer. The braking force is applied to the brake cylinders and is controllable by a braking ECU, which braking ECU is connected to a standards compliant communication bus on the trailer. The ECU is adapted to receive data inputs from sensors on the trailer. The system further includes an arrangement to interface to trailer electronics and a communications interface. In use, the arrangement transmits a request to the device for a driver to apply a predetermined condition to the trailer to enable control functions to be actuated from a remote device.

A method for electronically controlling a vehicle deceleration of a brake slip-controlled vehicle comprising a pneumatic braking system includes detecting that at least one wheel of the vehicle has a brake slip that exceeds a setpoint brake slip; in response to detecting that at least one of the wheels of the vehicle has a brake slip that exceeds the setpoint brake slip, brake slip-controlling the at least one wheel in order to prevent a lockup of the at least one wheel; determining a braking effect caused by wheel brakes on the wheels of the vehicle; and adjusting brake pressures output at the wheel brakes of one or more non-brake slip-controlled wheels in order to adjust the induced braking effect. The brake pressures at the wheel brakes of all non-brake slip-controlled wheels are adjusted.

A system and method for braking a flat-towed vehicle based upon a braking pressure of a braking fluid in a braking circuit in the towing vehicle, the method includes measuring a piezoresistor voltage drop across a piezoresistor positioned within the braking circuit such that the piezoresistor voltage drop changes in response to the braking pressure within the braking circuit. Based upon the measured piezoresistor voltage drop, a motor frame duration is retrieved. A clutch engages the motor output shaft to initiate a clutch frame. Upon expiration of a programmed clutch delay, a motor frame initiates by supplying power to a motor. Upon expiration of the motor frame duration, power to the motor is interrupted. The clutch continues to be engaged for the duration of the clutch frame. The clutch releases allowing a capstan attached to the clutch to spin freely relative to the motor output shaft.

An assembly for an induction sensing tone ring is provided. A brake rotor includes a circular pocket. A tone ring is received in the circular pocket of the brake rotor. The brake rotor has a plurality of locating tabs, with each locating tab having a slope surface. The tone ring has a plurality of retaining tabs, with each retaining tab being received between two locating tabs of the brake rotor. A retaining ring is fitted in each locating tab slope surface of the brake rotor to press fit against the retaining tabs of the tone ring.

A low cost brake control system adapted to provide roll stability control on a trailer. The system comprises a brake control unit having a load, exhaust and backup valve. This control unit is adapted to control pneumatically and electrically first and second ABS relay valves, each of the ABS relay valves being assigned to a single brake channel adapted to control the braking pressure on the trailer. This enables accurate control of the brakes during a roll stability event.

In a method for stabilizing the driving behavior of a tractor-trailer combination, a tilting inclination variable is obtained and a tilting limit is determined on the basis of the tilting inclination variable and is prescribed to a vehicle movement dynamics control system. A vehicle movement dynamics control device carries out the method. In order to improve the stabilization of the driving behavior of tractor-trailer combinations with different loads of the individual vehicles, the respective tilting inclination variable is determined at a plurality of vehicles of the tractor-trailer combination, and the value of the tilting inclination variable for the determination of the tilting limit which is decisive for the determination of the tilting limit is obtained from the tilting inclination variables.

In a method for controlling an electronic braking system for vehicles, in particular for trailer vehicles, signals of wheel-speed sensors are processed. At least signals of one or more sensors that are not wheel-speed sensors are processed for a detection of motion and/or standstill.

A brake control unit includes a processor, a first high side driver and a second high side driver. The processor sends signals to the first high side driver and the second high side driver. The first and second high side drivers process the signals independent of each other. The processor diagnoses faults and locations of faults based on feedback from the high side drivers. The first high side driver controls the braking of a first trailer brake. The second high side driver controls the braking of a second trailer brake.
