Abstract

The present application provides a method and device for distributing the torque of a hybrid vehicle, and an intelligent networked vehicle system, wherein the method for distributing the torque of a hybrid vehicle proposed in the present application acquires The speed information of driving on the preset road section makes the obtained speed information high in real time, and uses the preset algorithm to iteratively optimize the preset parameter value based on the speed information and slope information to obtain the optimized parameter value, so that The optimized parameter value obtained after iterative optimization matches the vehicle to be tested, so that the torque information obtained by the target vehicle based on the optimized parameter value and driving information is more suitable for the target vehicle, and then the target vehicle is assigned After the corresponding torque, the fuel consumption of the target vehicle can be better reduced, the effect of reducing the fuel consumption of the vehicle is improved, and the optimization of the vehicle energy control method is realized.

Description

technical field [0001] The present application relates to the field of vehicle technology, in particular to a method and device for allocating torque of a hybrid vehicle, and an intelligent networked vehicle system. Background technique [0002] In the vehicle industry, it is necessary to optimize the method of controlling vehicle energy. For example, if the vehicle is a hybrid vehicle, the motor torque and engine torque of the hybrid vehicle can be adjusted according to the required torque information corresponding to the hybrid vehicle. The torque is distributed to achieve the purpose of reducing the fuel consumption of the vehicle under the premise of ensuring the normal driving of the vehicle. [0003] In the prior art, the vehicle's fuel consumption is reduced by acquiring the historical vehicle speed data of the vehicle traveling on a preset road section, determining the corresponding torque information of the vehicle based on the historical vehicle speed data, and the...
