The invention relates to a method for emergency braking of a commercial vehicle (1), preferably an autonomous commercial vehicle (2), the commercial vehicle (1) having a pneumatic brake system (4) with a main service brake system (10) and a parking brake system (14), the main service brake system (10) having a main electronic service brake control unit (14) for controlling the main service brake system (10) and service brake actuators (16a, 16b, 16c, 16d), and the parking brake system (14) having a parking brake actuator (16a, 16b, 16c, 16d). The parking brake system (12) has an electronic parking brake control unit (18) for controlling the parking brake system (12) and the parking brake actuators on the at least one axle (HA). The pneumatic brake system (4) is configured to receive an emergency brake signal (SN). The method comprises the steps of: receiving an emergency brake signal on the main electronic service brake control unit (14); braking the commercial vehicle (1) by means of the main service brake system (10); according to the invention, the commercial vehicle speed (VF) is determined and the parking brake actuator (42a, 42b) is actuated by the parking brake system (12) when a predetermined speed threshold value is below and/or after a predetermined emergency braking time.

    本发明涉及用于使商用车(1)、优选自主式商用车(2)紧急刹停的方法,其中,商用车(1)具有配备了主行车制动系统(10)和驻车制动系统(14)的气动制动系统(4),其中,主行车制动系统(10)具有用于控制主行车制动系统(10)和行车制动执行器(16a、16b、16c、16d)的主电子行车制动控制单元(14),并且驻车制动系统(12)具有用于控制驻车制动系统(12)和至少一个车桥(HA)上的驻车制动执行器的电子驻车制动控制单元(18)。气动制动系统(4)被构造成用于接收紧急刹停信号(SN)。方法包括步骤:在主电子行车制动控制单元(14)上接收紧急刹停信号;通过主行车制动系统(10)使商用车(1)制动;获知商用车速度(VF)并且在低于预定的速度阈值时和/或在预定的紧急刹停时间之后,通过驻车制动系统(12)操纵驻车制动执行器(42a、42b)。
