A work vehicle is provided with a body and ground engaging means configured to allow motion of the body on ground, and braking means for locking ground engaging means, and an operative element carried by said body and configured to execute a specific working operation. The work vehicle further includes a first and a second joystick configured to respectively control the operation of ground engaging means and operative element based on movement of joystick and first and second input means configured respectively to control the activation/deactivation of parking brake functionality of the work vehicle and the activation/deactivation of hydraulic systems of work vehicle. Furthermore, the work vehicle includes a control system configured to receive second and first control signals derived from first and second input means respectively and each configured to assume a respective activation value and a respective deactivation value and inhibit the operation of the joystick linked to the operation of ground engaging means if both control signals are in activation state.

A line-locking brake system consists of a brake pressure generator which, in conjunction with a brake fluid solenoid isolates the front brake circuit from the master cylinder while maintaining a precise brake pressure in the front brake hydraulic system. The brake pressure generator consists of a pressure amplifier having a high pressure chamber located in the flow path from the master cylinder to the front brake cylinders and a low pressure chamber in fluid communication with a regulated gas pressure source. When activated, the brake pressure generator applies a pressure to the front brake circuit that is directly proportional to the pressure of the regulated gas and therefore is precisely controllable irrespective of wear on parts, driver fatigue or other variables.

Systems and methods for controlling a vehicle. One example system includes a deceleration actuator coupled to a first wheel of the vehicle and an electronic processor communicatively coupled to the deceleration actuator. The electronic processor is configured to receive a vehicle park command. The electronic processor is configured to, responsive to receiving the vehicle park command, determine a maximum holding pressure threshold. The electronic processor is configured to determine a requested braking pressure for the deceleration actuator. The electronic processor is configured to determine whether the requested braking pressure exceeds the maximum holding pressure threshold. The electronic processor is configured to, responsive to determining that the requested braking pressure does not exceed the maximum holding pressure threshold, control the deceleration actuator to apply, to the first wheel during a hold time, a holding braking pressure equivalent to the requested braking pressure.

The present relates to a method for operating a vehicle brake system which comprises a vehicle brake having a brake piston, an electrohydraulic service brake device, and an electromotive parking brake device having a spindle drive driven by an electric motor, wherein the electrohydraulic service brake device and/or the electromotive parking brake device act on the brake piston. The method determines an additional brake fluid volume to be delivered by the electrohydraulic service brake device in order to ensure a target clamping force (Fz-Soll) for a brake pad of the parking brake on application of the parking brake device.
