The invention relates to a method (100) for operating a vehicle (1) having an electric drive train (2), the electric drive train (2) being fed via a DC voltage source (3) and a converter (4) for converting a DC voltage into a single-phase or multi-phase AC voltage, comprising the following steps: determining (110) that the vehicle (1) is parked; checking (120), by means of at least one predefined criterion (10), whether the vehicle (1) is predicted to be parked only momentarily; -in response to the prediction of the vehicle (1) to be parked only briefly, placing (130) the vehicle (1) from a ready-to-travel state into a locked state in which the vehicle (1) is protected against unauthorized use, however, the converter (4) continues to be supplied with a DC voltage from the DC voltage source (3), and-in response to the prediction of the vehicle (1) to be parked only briefly, placing (130) the vehicle (1) from the ready-to-travel state into a locked state in which the vehicle (1) is protected against unauthorized use, while the converter (4) continues to be supplied with a DC voltage from the DC voltage source (3); in response to a prediction that the vehicle (1) is not only parked momentarily, at least one functional check of the electric drive train (2) is carried out (140), said functional check being provided for shutting down the electric drive train (2), and the vehicle (1) is brought into a shut-off state (150) after the functional check has ended; in the switched-off state, the vehicle (1) is protected against unauthorized use and the supply of the converter (4) from the DC voltage source (3) is interrupted.

    一种用于运行具有电驱动系(2)的车辆(1)的方法(100),其中,所述电驱动系(2)经由直流电压源(3)和用于将直流电压转换成单相或多相的交流电压的转换器(4)馈电,所述方法具有以下步骤,‑确定(110)所述车辆(1)停放;‑借助至少一个预先给定的标准(10)检查(120)所述车辆(1)是否预测仅短暂地停放;‑对所述车辆(1)预测仅短暂地停放进行响应,将所述车辆(1)从准备行驶的状态置于(130)锁止状态中,其中,在所述锁止状态中保护所述车辆(1)以防未经授权的使用,然而所述转换器(4)继续保持被供给以来自所述直流电压源(3)的直流电压;‑对所述车辆(1)预测不是仅仅短暂地停放进行响应,执行(140)所述电驱动系(2)的至少一个设置用于关机所述电驱动系(2)的功能检查,并且在所述功能检查结束之后将所述车辆(1)置于关断状态中(150),在所述关断状态中保护所述车辆(1)以防未经授权的使用并且中断来自所述直流电压源(3)的对所述转换器(4)的供给。
