The invention provides a vehicle air-fuel ratio adjusting method and device, electronic equipment, a storage medium and a vehicle. The method comprises the steps that under the conditions that it is detected that the temperature corresponding to a lean-burn NOx trap is within a preset temperature range and the opening degree of an accelerator pedal is increased, the current engine torque and the charge state of a power battery are obtained, determining a power target torque; if the state of charge is larger than the preset threshold value, the difference value between the power target torque and the current engine torque serves as the target output torque, and power is supplied to the motor through the power battery so that the motor can output the target output torque; and if the charge state is not larger than the preset threshold value, the fuel injection quantity of the engine is increased, the engine is controlled to be increased to the power target torque from the current engine torque, the engine is controlled to charge a power battery, and the air-fuel ratio of the engine is reduced to the second air-fuel ratio from the first air-fuel ratio. By means of the technical scheme, nitrous oxide emission is reduced when the vehicle is accelerated, and pollution to the environment is reduced.

    本申请提供一种车辆空燃比调整方法、装置、电子设备、存储介质及车辆,该方法包括:在检测到稀燃NOx捕集器对应的温度处于预设温度范围且检测到油门踏板开度增加的情况下,获取当前发动机扭矩以及动力电池的荷电状态,并确定动力目标扭矩;若荷电状态大于预设阈值,则将动力目标扭矩与当前发动机扭矩的差值作为目标输出扭矩,并通过动力电池为电动机供电以使电动机输出目标输出扭矩;若荷电状态不大于预设阈值,则增加发动机的喷油量,控制发动机由当前发动机扭矩增加至动力目标扭矩,并且控制发动机向动力电池充电,使发动机的空燃比由第一空燃比降至第二空燃比。通过本申请的技术方案,实现了在车辆加速时减少氧化亚氮排放,降低对环境的污染。
