Multi-working-condition working mode conversion method and system for heavy truck

Abstract

The invention provides a multi-working-condition working mode conversion method for a heavy truck. The method comprises: setting and storing the mapping relation between the working environment and working conditions of the heavy truck; setting and storing a corresponding relation between the working condition and the working mode of the heavy truck; obtaining a current working environment of theheavy truck, searching a corresponding working condition according to the current working environment, and starting a matching working mode of the corresponding working condition. meanwhile , the invention further provides a system based on the method, the problem that the working mode of an existing heavy truck is easy to control is solved, the requirement for multi-working-condition changes of the heavy truck is met, the requirement of a driver for controlling and processing the working conditions is met, meanwhile, control accuracy is guaranteed, and the driving automation degree is improved.

Description

technical field [0001] The invention belongs to the technical field of automobiles, and in particular relates to a method and system for switching working modes of heavy-duty trucks in multiple working conditions. Background technique [0002] With the rapid development of science and technology, the utilization rate of heavy-duty trucks is gradually increasing. In consideration of the precise control of driving and safety, people pay more attention to the multi-working mode of heavy-duty trucks. [0003] At present, most of the heavy-duty trucks realize the so-called multi-working mode by limiting the engine torque and power. Impact. [0004] The above-mentioned method does not control the heavy-duty truck according to the actual working conditions, that is, it does not take into account the loading situation, regional conditions and road conditions, so that the performance of the vehicle in terms of power and fuel economy is average; there is only a distinction between po...

Problems solved by technology

[0004] The above-mentioned method does not control the heavy-duty truck according to the actual working conditions, that is, it does not take into account the loading situation, regional conditions and road conditions, so that the performance of the vehicle in terms of power and fuel economy is average; there is only a distinction between power modes and the economic model, the distinction method is too simple and cannot adapt to the complexity of vehicle conditions and the diversity of driver needs
