Problems solved by technology
[0002] Due to the impact of the ambient temperature or the vehicle is affected by some reasons (low battery or battery pack itself), the charging or discharging power of the battery pack is limited, and the vehicle will face poor drivability. If the vehicle energy management strategy is not properly controlled, It will lead to high fuel consumption of the vehicle, what's more, the vehicle may have overvoltage and overcharge failures, which reduces the safety of the vehicle

The embodiment of the invention provides a vehicle generation power control method and device, a storage medium and computer equipment. The method comprises the following steps: generating power generation demand power based on a driver model according to acquired road information, pedal opening information and vehicle state information; according to the deviation power between the power generation demand power and the actual consumed power of the vehicle and the change rate of the deviation power, generating the optimal power generation demand power based on the optimal parameter of a fuzzy PID controller; inputting the optimal power generation demand power into a whole vehicle dynamic model to generate vehicle power generation power; and sending the vehicle generated power to a range extender, so that the range extender works according to the vehicle generated power. In the method provided by the embodiment of the invention, the range extender works according to the vehicle generation power calculated by the vehicle dynamics model, so that the vehicle can be ensured not to have the fault problem of overcharge and overvoltage, and the safety of the vehicle is improved.
Description
【Technical field】 [0001] The present invention relates to the technical field of vehicles, in particular to a method, device, storage medium and computer equipment for controlling power generated by a vehicle. 【Background technique】 [0002] Due to the impact of the ambient temperature or the vehicle is affected by some reasons (low battery or battery pack itself), the charging or discharging power of the battery pack is limited, and the vehicle will face poor drivability. If the vehicle energy management strategy is not properly controlled, It will lead to excessive fuel consumption of the vehicle, what's more, the vehicle may have overvoltage and overcharge failures, which reduces the safety of the vehicle. 【Content of invention】 [0003] In view of this, embodiments of the present invention provide a method, device, storage medium and computer equipment for controlling power generated by a vehicle, so as to improve the safety of the vehicle. [0004] In one aspect, an ...
