Hybrid vehicle control method and device, storage medium and vehicle

Abstract

The invention relates to a hybrid vehicle control method and device, a storage medium and a vehicle. The method comprises the steps that a road section with the vehicle average demand power not lower than first preset power in target route information is determined as a first road section, and a road section with the vehicle average demand power not higher than second preset power in the target route information is determined as a second road section; when the first road section is connected with the second road section and the first road section is in front of the second road section, determining the first road section and the second road section as target road sections; and determining the target electric quantity required for pure electric driving of the vehicle in the second road section in the target road sections, and controlling the driving mode of the vehicle in the first road section in the target road sections according to the target electric quantity, so that pure electric driving can be performed in the second road section with relatively low average required power of the vehicle, the fuel consumption is reduced, and the driving cost is saved. The requirement for starting the engine in the second road section with the low average vehicle demand power is reduced, the starting and stopping frequency of the engine is reduced, and the service life of the engine is prolonged.

Description

technical field [0001] The present disclosure relates to vehicles, and in particular, relates to a hybrid vehicle control method, device, storage medium and vehicle. Background technique [0002] A common energy management strategy for hybrid electric vehicles is to use the energy of the power battery first, that is, when the SOC (State of charge, state of charge) of the power battery is high, pure electricity is given priority, and when the SOC of the power battery is low, the hybrid drive requires only Just ensure that the SOC of the power battery is not lower than the preset minimum threshold. [0003] However, for hybrid electric vehicles, in order to reduce fuel consumption and maximize the use of electric drive energy, it is best to use pure electric drive under low power demand conditions, but according to the energy management strategy in the prior art , it does not guarantee that the battery SOC can meet the pure jog drive when the vehicle has a low power demand, s...
