The invention discloses a method for controlling the working state of a vehicle, and the method comprises the steps: determining the oil pressure fault level of the to-be-controlled vehicle based on the working condition of the to-be-controlled vehicle according to a preset oil pressure reasonable range, and a main oil pressure a and a clutch oil pressure b which are obtained in real time; whereina is greater than or equal to 0 bar, and b is greater than or equal to 0 bar; sending the oil pressure fault level to a vehicle control unit, so that the vehicle control unit determines a target working state of the to-be-controlled vehicle according to a preset corresponding relation and controls the to-be-controlled vehicle to enter the target working state; wherein the preset corresponding relation is the corresponding relation between the oil pressure fault level and the target working state. Correspondingly, the invention further provides a device for controlling the working state of thevehicle. By adopting the embodiment of the invention, when the hydraulic system of the hybrid electric vehicle fails, the processing efficiency of the system failure can be effectively improved, so that the efficiency of controlling the vehicle to enter a working state is improved, and the drivability of the vehicle is improved.
本发明公开了一种控制车辆工作状态的方法,包括步骤:基于待控制车辆所处的工况,根据预设的油压合理范围、实时获取到的主油压a和离合器油压b,确定所述待控制车辆的油压故障等级;其中,a≥0bar,b≥0bar;发送所述油压故障等级至整车控制器,使得所述整车控制器根据预置对应关系确定所述待控制车辆的目标工作状态,并控制所述待控制车辆进入所述目标工作状态;其中,所述预置对应关系为所述油压故障等级和所述目标工作状态的对应关系。相应地,本发明还提供一种控制车辆工作状态的装置。采用本发明实施例,能在混合动力汽车的液压系统出现故障时,有效提高系统故障的处理效率,从而提高控制车辆进入工作状态的效率,提高车辆的驾驶性能。
