The embodiment of the invention provides a fusion security demand generation method, electronic equipment and a storage medium. According to the method, in the development process of the automatic transverse control function of the heavy vehicle, transverse control function related items including an implementation function and an expected function are defined, hazard events of the transverse control function related items are obtained through danger and operability analysis, and the risk of the transverse control function related items is analyzed through a hazard and risk analysis method. The method comprises the steps of obtaining a safety target of a hazardous event, a vehicle safety integrity level and residual risk acceptance, obtaining a target risk level in a risk level table according to the vehicle safety integrity level and the residual risk acceptance, establishing a functional safety architecture according to the target risk level and the safety target, obtaining a safety constraint condition based on the functional safety architecture, and sending the safety constraint condition to a server. And the safety constraint body condition is converted into the target safety requirement to analyze the harm caused by the transverse control failure and the expected insufficient function, so that the development efficiency of the automatic transverse control function is improved, the development period is shortened, and the reliability and the safety are improved.
