Embodiment Construction

[0042] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0043] At present, hybrid electric vehicles have a variety of powertrain configurations, such as series, parallel, and hybrid configurations. After the configuration of the hybrid electric vehicle powertrain is determined, there are different vehicle energy management strategies. Therefore, in order to illustrate that the method for calibrating the vehicle controller of a hybrid electric vehicle described in the present invention has universal applicability, its application flow in a specific embodiment is specifically cited. What needs to be explained is that the change of the embodiment does not constitute a Innovations to the present invention.

[0044] Such as figure 1 As shown, in the embodiments of the present invention, the hybrid electric vehicle powertrain is a typica...

Abstract

The invention discloses a calibrating method of a whole-vehicle controller of a hybrid power vehicle. The method comprises the steps that step 1, a whole-vehicle controller calibrating system is established; step 2, one-dimensional calibrating parameters are extracted taking fuel consuming amount and electricity consuming amount as calibrating goals under the premise that the power performance ofthe whole vehicle is met and a feasible domain is determined; step 3, a longitudinal neural network is established as a calibrating system surrogate model, parameter sensitivity analysis is conductedto determine key influencing parameters, and parameters with weaker influences are set as constants; step 4, calibrating routes of each parameter are obtained based on main effect graphs of the influence on the calibrating goals on multiple levels of each parameter, and local confidence intervals of each parameter are obtained from the main effect graphs; step 5, an overall theoretical optimal calibrating parameter combination is obtained based on the calibrating system surrogate model, the calibrating routes of each parameter and local sensitivity confidence intervals of each parameter. By means of the calibrating method, the whole-vehicle controller of the hybrid power vehicle can be rapidly calibrated.

Description

technical field [0001] The present invention relates to the technical field of calibrating a vehicle controller of a hybrid electric vehicle, and more specifically, the present invention relates to a method for quickly calibrating a vehicle controller of a hybrid electric vehicle. Background technique [0002] Facing the challenges of global energy shortage and environmental pollution, the world's automotive technology innovation is getting faster and faster, and the current automotive technology is developing in the direction of low-carbon, intelligent, and informationalization. As one of the most important forms of energy-saving driving in the automotive industry, hybrid electric vehicles are the focus of research in the global industry. Among them, the vehicle control unit (Vehicle Control Unit, VCU) is one of the core components of the hybrid electric vehicle, and it is the basis of the vehicle energy management strategy. Its main function is to realize the vehicle energ...
