The invention relates to a method for controlling a work vehicle (2) to change the direction of travel between a forward travel and a reverse travel or vice versa, the work vehicle (2) has an electronically controllable hydrostatic travel drive (3), a motorized brake system (22) having at least one electronically controllable brake circuit (106), and an electronic brake control unit (40) for controlling the travel drive (3) and the at least one electronically controllable brake circuit (106) of the brake system (22), and in which the brake system (22) is electrically controlled by the brake control unit (40). During travel in a first travel direction (15), a change of the travel direction to a travel direction (17) opposite the first travel direction is triggered by switching (69) the hydrostatic travel drive (3) by means of an associated manual operating element (70). In order to reduce the mechanical load on components of the hydrostatic drive train (3.1) of the travel drive (3), it is provided that the deceleration of the work vehicle (2) is supported by an automatic actuation of brakes (113a, 113b) of an electronically controllable brake circuit (106) of the brake system (22) when the mentioned travel direction change is carried out, the actuation of the brake (113a, 113b) is triggered by a switch (69) of the actuating element (70) and the brake is released again at the latest when the vehicle rest state (vF = 0) is reached.
本发明涉及用于控制作业车辆(2)在前进行驶与倒退行驶之间或相反地变换行驶方向的方法,其中,作业车辆(2)具有:能电子控制的静液压行驶驱动器(3)、具有至少一个能电子控制的制动回路(106)的机动操纵的制动设施(22)、和用于控制行驶驱动器(3)以及制动设施(22)的至少一个能电子控制的制动回路(106)的电子的制动控制器(40),并且在其中,在朝第一行驶方向(15)行驶期间,通过借助配属的手动操作元件(70)对静液压行驶驱动器(3)进行切换(69)来触发将行驶方向变换至与第一行驶方向相反的行驶方向(17)。为了减少行驶驱动器(3)的静液压驱动系(3.1)的构件所受的机械负荷而设置的是,在执行所提及的行驶方向变换的情况下,通过对制动设施(22)的能电子控制的制动回路(106)的制动器(113a、113b)的自动操纵来支持作业车辆(2)的减速,其中,通过操作元件(70)的切换(69)来触发操纵制动器(113a、113b),并最迟在达到车辆静止状态(vF=0)时再次松开制动器。
