A tire pressure control device of an off-road vehicle is configured for changing tire pressures of vehicle wheels of at least one vehicle axle. Each pneumatic tire has a pressure-controlled wheel valve which is pneumatically connected to a control pressure line and to a supply pressure line. The control pressure lines and the supply pressure lines are pneumatically connected to a compressed air supply device and controlled by an electronic control unit. The actuation of the wheel valves takes place axle by axle via control valves, and the compressed air supply of the vehicle wheels is carried out by side via supply valves.

A method for braking a vehicle, including checking whether a trigger criterion for braking the vehicle is present, and if the trigger criterion is satisfied, causing a conditioning braking pulse through brief pulsed braking such that passengers experience brief braking of the vehicle, and immediately thereafter initiating a braking phase in which the vehicle is braked in at least two partial braking regions by an actual ego deceleration that varies with respect to time, wherein each partial braking region is extended over a partial braking interval and merge into one another without the actual ego deceleration changing abruptly, and the actual ego deceleration in at least one of the partial braking regions is changed continuously over the respective partial braking interval such that a different actual jerk is obtained in each partial braking region, and wherein the actual jerk behaves degressively over at least some partial braking regions.

A working vehicle () for use in agriculture is configured for mounting a laterally protruding implement on the vehicle front or vehicle rear. The vehicle has an electronically controllable drive motor (), an electronically controllable brake system (), a sensor arrangement () for measuring rotational movements or rotational oscillations about at least one of three reference axes, and an electronic control device () for evaluating sensor data and for activating the drive motor () or the brake system (). A data storage () stores threshold values for the sensor data. The control device determines characteristic values for the respective rotational movement or rotational oscillation and decides whether a reduction in travel speed is required in view of the threshold values. If true, the travel speed is reduced until the characteristic value reaches or falls below the threshold value.
