A traction application executing on a vehicle control module receives a traction speed control input to control a traction wheel of the vehicle. Based on the traction speed control input, the traction application determines a first setpoint value of a control attribute related to the traction wheel. A first diagnostic supervisor receives a measured value of the control attribute related to the traction wheel, and the first setpoint value from the traction application. The first diagnostic supervisor comprises a first model of a traction system of the vehicle. Based on the first setpoint value and the first model, the first diagnostic supervisor calculates a first virtual value of the control attribute related to the traction wheel. Based on the first virtual value and the measured value of the control attribute, the first diagnostic supervisor determines a first operating condition of the traction system of the vehicle.

A steering application executing on a vehicle control module receives a steering control input to control a steered wheel of a vehicle. Based on the steering control input, the steering application determines a traction threshold value associated with a traction control attribute related to a traction wheel of the vehicle. A first diagnostic supervisor executing on the vehicle control module receives a measured value of the traction control attribute and the traction threshold value. When the measured value of the traction control attribute exceeds the traction threshold value, the first diagnostic supervisor repeatedly calculates a respective difference between the traction threshold value and the measured value of the traction control attribute to generate a set comprising a plurality of the respective differences. Based on the plurality of respective differences, the first diagnostic supervisor determines a first operating condition of a traction system of the vehicle.

A work vehicle includes a variable displacement hydraulic pump driven by an engine, a hydraulic motor forming a closed circuit with the pump and driven by hydraulic fluid discharged from the pump, wheels driven by the motor to allow the work vehicle to travel, a selector detecting an operating state of a switch switching the traveling of the work vehicle between forward and backward, and a controller. When the selector detects a reversal operation of the switch to reverse the traveling direction when the work vehicle travels, the controller sets relationship between the vehicle speed of the work vehicle and the upper limit of the rotational speed of the engine such that the upper limit increases as the absolute value of the vehicle speed approaches zero. The controller obtains an upper limit of the rotational speed from the relationship and a vehicle speed of the work vehicle.

A method is disclosed for controlling a change in the direction of travel of a working vehicle between forward travel and rearward travel or vice versa. The working vehicle has an electronically controllable hydrostatic travel drive, a power-operated brake system with at least one electronically controllable brake circuit, and an electronic brake-control unit for controlling the travel drive and the brake circuit. While the vehicle is traveling in a first direction, a change in the direction of travel is triggered by a switchover of the hydrostatic travel drive by means of an assigned manual operating element. To reduce the mechanical loading, the deceleration of the working vehicle can be assisted by automatically actuating the brakes of the electronically controllable brake circuit, where these brakes are actuated by being triggered by the switchover of the operating element and are released by the time the vehicle comes to a standstill.
