摘要： The embodiment of the invention provides a predictive power control system for hybrid vehicles. The system is mainly specific to the application scenarios of long-distance freight heavy trucks. Based on the vehicle configuration parameters and the current operating conditions, and with the aid of a vehicle-mounted expressway electronic navigation three-dimensional map, the system can be used to accurately and real-timely predict the dynamic road load power time-space function within the range of tens of kilometers of the electronic horizon in front of the vehicle; an electric power shunt device is commanded through a vehicle controller, and the flow direction and amplitude of 100-kilowatt level electric power can be accurately and continuously adjusted among an engine-driven generator set, a battery pack and a driving motor within tens of milliseconds of system response time so that an engine works stably in the high efficiency area of the engine for a long time; and the road load transient power balance required by a vehicle dynamic equation can be met through hundreds of kilowatts of fast charging and discharging of the battery pack in real time. Compared with traditional diesel heavy trucks, the hybrid heavy truck has the advantage that the overall fuel consumption and emissions in real world operation are reduced greatly on the premise of ensuring the vehicle power, freight timeliness and driving safety.

摘要： An ACE heavy truck fuel saving system provided by the present disclosure is based on a double-motor mixed hybrid powertrain system architecture, especially an electrical power split device. Under the condition that no new hardware device is added, the transmission path, direction and amplitude of hundred-kilowatt-level mechanical or electric power flow among all vehicle-mounted power subsystems are dynamically regulated and controlled through software definition or remote iteration updating, new functions of vehicle longitudinal driving control and electromechanical energy management are flexibly established or the existing functions are timely improved, the SAE L1-level automatic driving function is achieved, therefore, the power performance, fuel consumption, pollutant emission and active safety of the complete vehicle can be optimized at the same time, and the actual energy-saving and emission-reducing effect of ACE heavy truck operation is basically decoupled from the performance of a vehicle engine and the driving level of a driver. A cloud-end and vehicle-end collaborative fuel saving data set is combined with a machine learning fuel saving algorithm, so that the fuel saving system has the capabilities of automatic learning and autonomous evolution in the life cycle of the vehicle, and energy saving and emission reduction of the vehicle can be continuously optimized.

摘要： A power supply module for a vehicle comprises a battery system (13) including a first output terminal (Out 1) and a second output terminal (Out 2), wherein the battery system (13) is connected with a AC/DC converter (12) of the vehicle, the AC/DC converter (12) includes a DC terminal (DC) and an AC terminal (AC), the DC terminal (DC) is connected with the first output terminal (Out 1) of the battery system (13) and the AC terminal (AC) is connected to a motor generator (11) of the vehicle cooperating with the power supply module (10), so as to form a first output (i1), wherein the second output terminal (Out 2) is connected to a power supply distribution center (17) of the vehicle, so as to form a second output (i2), and wherein the battery system (13) includes a lead-carbon battery. There are also provided a power supply system comprising the power supply module for a vehicle, a vehicle comprising the power supply system for a vehicle, and a method of arranging a power supply module for a vehicle. The lithium ion battery and the battery management system in the prior art are replaced with the lead-carbon battery. As the working environment temperature has little influence on the lead-carbon battery, the freedom for the arrangement position of the lead-carbon battery is increased. It is no longer necessary to arrange the lead-carbon battery away from the engine, or additionally take heat preservation factors into account. The lead-carbon battery may be arranged under the engine hood or next to the engine. As a result, the length of the cable required for connection will be greatly shortened, which effectively lowers the manufacturing cost.
