A method and system for converting working modes of heavy-duty trucks under multiple working conditions

Abstract

The invention provides a method for switching working modes of heavy-duty trucks under multiple working conditions, the method comprising: setting and storing the mapping relationship between the working environment and working conditions of heavy-duty trucks; setting and storing the working conditions and working modes of heavy-duty trucks The corresponding relationship; obtain the current working environment of the heavy-duty truck, and search for the corresponding working condition according to the current working environment, and start the matching working mode of the corresponding working condition; at the same time, the present invention also provides a system based on the above method to solve It solves the problem of simple control of the working mode of the existing heavy-duty trucks, adapts to the changing requirements of multiple working conditions of heavy-duty trucks, satisfies the driver's control of the working conditions, and at the same time ensures the accuracy of the control and improves the degree of driving automation.

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
