A trailer brake system that generates load-dependent braking forces. Variable trailer load information is used to generate load-dependent control signals which serve to control an electrically-controlled proportional valve. A load sensing valve serves to modify brake command signals in dependence on a control pressure that is regulated by the proportional valve.

A vehicle weight sensing system particularly useful for trailers. An axle tube is mounted to the vehicle or trailer through its suspension members that may be leaf springs. A mounting block is affixed to the axle tube for mounting a strain gauge. The mounting block is fixed to the axle tube between the suspension members connected to the axle tube. The mounting block has a mounting surface opposite to the mating surface and a notch extends from the mating surface toward the mounting surface. The notch terminates between the mating surface and the mounting surface. The notch separates rigidified sections of the mounting block and the rigidified sections straddle the notch. The stain gauge measures strain in the axle and thereby generates a signal proportional to the weight on the trailer. The signal can be used to properly proportion a brake system on the trailer.

A braking force control system for an agricultural system includes a controller including a memory and a processor. The controller is configured to receive a first signal indicative of a first input braking force of a towable implement brake system of a towable implement of the agricultural system, receive a second signal indicative of a first weight of an agricultural product within the towable implement at a first time, determine a first target braking force of the towable implement brake system based at least in part on the first signal and the second signal, determine whether a first current braking force of the towable implement brake system corresponds to the first target braking force of the towable implement brake system, and output to the towable implement brake system, in response to determining that the first current braking force of the towable implement brake system does not correspond to the first target braking force of the towable implement brake system, a third signal indicative of the first target braking force of the towable implement brake system.

A control device is for a vehicle and a method is for improving the measuring accuracy of an on-board vehicle axle load measurement system during a loading or unloading process and/or during the levelling of a stationary vehicle, wherein a wheel brake is assigned to each vehicle wheel, and wherein each wheel brake is actuatable via an on-board vehicle electronic braking system. The control device is configured to control the electronic braking system such that the latter, by the repeated engagement and/or release of at least one or more of the wheel brakes, reduces mechanical stresses within the vehicle body which impair the accuracy of the axle load measurement system. A method is for operating this control device.

A trailering system of a vehicle includes: a trailer hitch configured to receive a ball, the ball configured to be coupled to trailers for towing; a force sensor configured to measure at least one of: a first force on the trailer hitch in a longitudinal direction of the vehicle; a second force on the trailer hitch in a latitudinal direction of the vehicle; and a third force on the trailer hitch in a vertical direction; and a display module configured to selectively indicate a present condition of a trailer that is coupled to the trailer hitch based on the at least one of the first force, the second force, and the third force.

A method for operating an electromechanical brake booster. A pedal force is ascertained, a brake pressure is ascertained from the pedal force by an actuator, and the brake pressure applied to frictional brakes is set, thereby producing a vehicle deceleration. The actuator has a standard configuration wherein, in response to the pedal force, a brake pressure is ascertained that produces a specified standard deceleration of the motor vehicle if a specified disturbance variable has a specified standard value. The influence of the disturbance variable on the vehicle deceleration is compensated. The actuator has at least one control parameter for setting a compensation configuration, an actual value of the disturbance variable is detected, and the compensation configuration is set based on the respective difference between the ascertained actual value and the standard value.

A weight profile determination system may be provided that includes a sensor and a controller. The sensor may be disposed along a route and configured to generate a plurality of force measurements of a vehicle system moving on the route relative to the sensor. The force measurements may be obtained at different times and correspond to different locations along a length of the vehicle system. The controller may determine a weight profile for the vehicle system based on the force measurements generated by the sensor. The weight profile can represent a distribution of weight along the length of the vehicle system. The controller may communicate the weight profile to one or more of the vehicle system or an offboard device for controlling movement of the vehicle system based on the weight profile.

A method for determining a trailer brake magnitude for a trailer brake system of a trailer being towed by a vehicle includes determining connection of a trailer to a vehicle, determining at least one trailer parameter relating to a size, shape or a weight of the trailer, and determining a trailer braking magnitude as a function of the at least one trailer parameter.
