A dual-motor mixed-hybrid powertrain system of the disclosure, by performing pulse modulation control, i.e., series-hybrid intelligent start-stop control (iSS) or parallel-hybrid intelligent power switching control (iPS), on the instantaneous power time-varying functions of an engine and a battery pack, can convert the complex surface working condition of an analog electric control (AEC) engine in the prior art into a simpler line working condition of a digital pulse control (DPC) engine, either a pre-determined high-state line working condition in the high-efficiency combustion area or a pre-determined non-combustion low-state line working condition with zero fuel consumption and zero pollutant emissions multiplexed in time; The traditional fixed one-to-one bidirectional mapping relationship between an engine working condition and a vehicle working condition is converted into a dynamically adjustable many-to-many bidirectional mapping relationship to achieve the full coverage of any overall vehicle working condition. Achieving decoupling between a DPC engine working condition and the overall vehicle working condition and decoupling between software and hardware of a hybrid powertrain. By means of software defining and over-the-air upgrading, the vehicle power management strategy (PMS) can be customized quickly for each vehicle or each vehicle application scenario, to achieve online real-time global energy saving and emission reduction simultaneous optimization under the premise of industry leading vehicle power and braking performance and a thousand vehicle and a thousand face. An automatedconnected-electrified (ACE) heavy truck equipped with the software defined mixed hybrid powertrain can leverage the intelligent cruise control (iCC) technology to convert the technical problem of a long-haul ACE truck energy saving and emission reduction optimization into the equivalent Al problem of computer playing Go; using fuel saving big data, fuel saving machine learning algorithm, vehicle-cloud computation collaboration, an ACE truck operating under the iCC, can achieve real world fuel consumption better than that by a human driver; ensure that the real driving environment (RDE) exhaust NOx emission value to meet the emission standard reliably long term under the premise of fuel consumption minimization; The disclosure provides a technology solution, with high performance-to-price ratio and production ready, to meet both the 2027 US federal GHG-II regulation on CO2 and the California ultra-low NOx emission Omnibus regulations by 2025.
