METHOD FOR CONTROLLING BRAKE FORCES OF A WORKING MACHINE
A method is disclosed for controlling brake forces of a working machine, the working machine including a frame and two front wheels and two rear wheels mounted to the frame, the working machine further including a front wheel brake arranged to brake at least one of the front wheels, and a rear wheel brake arranged to brake at least one of the rear wheels, the front wheel brake being controllable independently of the rear wheel brake, and vice versa, the working machine further including an implement connected to the frame so as to be movable in relation to the frame. The method includes determining a position of the implement in relation to the frame, and distributing the brake forces between the front and rear wheel brakes at least partly based on the determined implement position.

METHOD FOR ADJUSTING BRAKE PRESSURES, BRAKE SYSTEM OF A MOTOR VEHICLE FOR CARRYING OUT SUCH METHOD, AND MOTOR VEHICLE COMPRISING SUCH A BRAKE SYSTEM
A method for adjusting brake pressures on wheel brakes of a motor vehicle includes adjusting, in a normal braking mode as a function of a driver's braking demand determined by a driver of the motor vehicle, the brake pressures on the wheel brakes. The method further includes carrying out, by a brake control unit in a pressure control mode, adjustment of the brake pressures on the wheel brakes to implement at least a drive stability function and/or external braking demands. Furthermore, the method includes determining, by the brake control unit, the brake pressures on the wheel brakes at least when implementing external braking demands while controlling an ideal pressure distribution ratio of the brake pressures at wheel brakes of the front axle to the brake pressures at wheel brakes of a rear axle of the motor vehicle, wherein the control function takes into account a pressure distribution ratio.
Method for Controlling a Brake System for Adjusting a Total Brake Torque Distribution Between a First and a Second Axle of a Motor Vehicle and a Brake System to Carry Out the Procedure
The invention relates to a method for controlling a braking system for setting a total braking torque distribution between a first and a second axle of a motor vehicle. The braking system includes a friction braking device and a recuperative braking device. The braking system has a total braking torque composed of a friction braking torque portion and a recuperative braking torque portion. The method include determining, for one axle, a minimal recuperation torque, which is set on that axle, and remains set on that axle for all driving situations as a recuperative braking torque portion.
ELECTRO-HYDRAULIC BRAKE SYSTEM AND METHOD
An electro-hydraulic brake system includes a first brake input that generates a first brake input signal and a second brake input that generates a second brake input signal. The system also includes a first valve that releases hydraulic fluid to control a first brake and a second valve that releases the hydraulic fluid to control a second brake. The system includes a speed sensor that generates a speed signal indicative of a speed of a work vehicle. A controller receives the speed signal, the first brake input signal, and the second brake input signal, determines the speed of the work vehicle based on the speed signal, and compares the speed of the work vehicle to a threshold speed. The controller synchronizes actuation of the first and second valves in response to the speed being in excess of the threshold speed to control the first and second valves.

Vehicle braking system brake bias adjuster having a visible brake bias ratio indicator and method and apparatus for retrofitting a vehicle with a vehicle braking system brake bias adjustment knob assembly having a visible brake bias ratio indicator
A vehicle braking system bias adjuster which includes a brake bias adjustment knob assembly which enables the driver of the vehicle to quickly and easily set, adjust, and visually and quickly determine the relative front to rear (or right front to left front) brake bias or brake bias setting of the vehicle before and while driving the vehicle. The brake bias adjustment knob assembly visually indicates the exact amount of brake bias, or if there is no bias at all. The ratio is expressed in numbers to enable the driver to reset the brake bias to a known value of ratio as needed for track conditions and vehicle weight changes. The value in numbers is reproducible. The present disclosure also provides a method and apparatus for retrofitting an existing vehicle with a brake bias adjustment knob assembly which enables the driver of the vehicle to quickly and easily set, adjust, and visually determine the relative brake bias or brake bias setting (i.e., the ratio of front to rear brake biasing or the ratio of side to side brake biasing) of the vehicle before and while driving the vehicle.

Brake control device for vehicle
A brake control device is applied to a brake device that controls a front-wheel braking force and a rear-wheel braking force. The brake control device includes a ratio calculation circuit that calculates a target front and rear braking force distribution ratio based on a target pitch angle, and a brake control circuit that performs a stability control by operating the brake device based on the target front and rear braking force distribution ratio during braking.
ELECTRONICALLY CONTROLLABLE PNEUMATIC BRAKING SYSTEM WITH FAILSAFE BRAKING APPLICATION FOR AUTONOMOUS DRIVING, HAVING ONLY ONE SHUTTLE VALVE
An electronically controllable pneumatic braking system for a vehicle includes a first control unit for a primary system and a second control unit for a first fallback level, and a monostable fail-safety valve unit which pneumatically connects a main port, which provides a first pressure, and a failure brake port. The fail-safety valve unit is connected to both control units and in a fault situation, power failure and/or diagnostic situation of the control units, provides the failure brake pressure for triggering a failure braking operation. The failure brake port is connected to the primary system and/or to the first fallback level upstream of a functional pneumatic unit of the primary system and/or the first fallback level, in such a way that both front axle service brake actuators and rear axle service brake actuators have a brake pressure applied thereto in order to implement the failure braking operation.
