The invention relates to an exhaust gas mixed heating system and method for a solid SCR system, and discloses a system and method for controlling a gaseous reducing agent aftertreatment system of a vehicle, a storage medium and a computing platform. The control is performed on one or more controllers. Exemplary embodiments includes the steps that the exhaust gas temperature is determined; the determined temperature is compared with a threshold value temperature; when the determined temperature is below the threshold value temperature, the exhaust gas is heated; the situation that the temperature of the heated exhaust gas is at or above the threshold value temperature is determined; and after the determination, a reducing agent delivery valve is opened. 本申请涉及用于固体SCR系统的废气混合加热的系统和方法。公开了用于控制交通工具的气态还原剂后处理系统的系统、方法、存储介质和计算平台，所述控制在一个或更多个控制器上执行。示例性实施方式可以：确定废气温度；将所确定的温度与阈值温度进行比较；当所确定的温度低于阈值温度时，加热废气；确定所加热的废气温度处于或高于阈值温度；并且在该确定之后打开还原剂输送阀。
