Abstract: Provided is a work vehicle capable of satisfying a user's demand to brake performance in a flexible manner. A wheel loader 1 comprises a controller 5 storing a plurality of control characteristics each of which is set such that a brake valve control pressure Pi of a solenoid proportional valve 45 increases as a pedal angle θ of a brake pedal 43 increases, and under the condition where a pedal angle θ is equal to or less than a predetermined pedal angle θ, an increase rate of the brake valve control pressure Pi with respect to the pedal angle θ varies. In a case where the pedal angle θ detected by a potentiometer 33 is equal to or less than the predetermined pedal angle θth, the controller 5, calculates the brake valve control pressure Pi based on the selected one control characteristic.

Abstract: A vehicle pedal stroke detection apparatus acquires a first value based on a physical amount regarding a magnetic flux of a magnet that is output from a stroke sensor. The first value is a physical amount regarding a magnitude of a magnetic flux density of the magnet with respect to a displacement of a push rod. Then, the vehicle pedal stroke detection apparatus compares the first value and a second value. The second value is a preset physical amount regarding the magnitude of the magnetic flux density of the magnet with respect to the displacement of the push rod.

Abstract: A device for a hydraulic braking system of a vehicle. The device includes a processing unit, which is programmed to determine at least one brake characteristic value of the hydraulic braking system, the processing unit being programmed to determine the at least one brake characteristic value as a vehicle axle-specific brake characteristic value, which in each case corresponds to a ratio between a brake pressure in all wheel brake cylinders assigned to a shared vehicle axle of the vehicle and a vehicle axle braking torque exerted on the shared vehicle axle with the aid of the wheel brake cylinders. A method for determining at least one brake characteristic value of a hydraulic braking system of a vehicle, and a method for decelerating a vehicle with a hydraulic braking system and an electric motor usable as a generator, are also described.
