The invention relates to the technical field of fire fighting trucks, and in particular relates to an electric control system of a chassis special for a series hybrid airport fire fighting truck. Thesystem comprises the steps that S1 a main driving motor and an auxiliary driving motor are started to jointly drive a chassis to run; and S2 the main driving motor is started to drive the chassis anda water pump motor to work; if the electric quantity SOC of a power battery is higher than the upper limit threshold value, an extended-range motor auxiliary power battery supplies power to the main driving motor; if the electric quantity SOC of the power battery is lower than the lower limit threshold value, an engine drives the extended-range motor to generate power, and the extended-range motorcharges the power battery and supplies power to the main driving motor; if the electric quantity SOC of the power battery is greater than the lower limit threshold and less than the upper limit threshold, the engine drives the extended-range motor to supply power to the main driving motor, and the power battery assists the extended-range motor in supplying power to the main driving motor. The problems that a traditional chassis is single in power source, waste gas is discharged when a vehicle enters and exits a garage, water pump work is affected by the work state of the engine, and the vehicle cannot run when the engine breaks down or a single motor breaks down are solved.
本发明涉及消防车技术领域,具体是一种串联混动机场消防车专用底盘的电控系统,S1:启动主驱动电机和辅驱动电机共同驱动底盘行驶,S2:启动主驱动电机驱动底盘,水泵电机工作;若动力电池电量SOC高于上限阈值,增程电机辅助动力电池为主驱动电机供电;若动力电池电量SOC低于下限阈值,发动机带动增程电机发电,增程电机对动力电池充电和对主驱动电机供电;若下限阈值<动力电池电量SOC<上限阈值时,发动机带动增程电机为主驱动电机供电,动力电池辅助增程电机给主驱动电机供电,本发明解决传统底盘动力源单一、车辆出入库排放废气问题、水泵工作受发动机工作状态影响问题、发动机故障或者单个电机故障时无法行驶的问题。
