Problems solved by technology

However, the existing gear decision-making system based on the optimal shift schedule of a single performance index cannot take into account power, economy, and The performance of the three types of emissions can obtain the comprehensive optimal gear; the shift schedule formulated by a certain combination of power and economy can seek a certain compromise between the two, but it is difficult to adapt to the individual needs of different drivers; and Although the gear decision system based on the shift rules extracted from the driver's operating experience can better realize the learning of the driver's operating experience, it is difficult to ensure that its performance is also optimal.

Embodiment Construction

[0082] The present invention will be further described below in conjunction with the accompanying drawings, taking a 5-speed mechanical automatic transmission (AMT) multi-performance comprehensive optimal gear decision-making system as a specific embodiment.

[0083]The 5-speed AMT multi-performance comprehensive optimal gear decision system consists of a shift schedule optimization module, a signal acquisition module, a driving intention recognition module, a target gear decision module, a shift execution module, a vehicle driving state database, and a shift schedule database. , whose structure is as figure 1 shown. The multi-performance comprehensive optimal shift schedule under different driving intentions represented by the shift performance expectation value is obtained by offline optimization calculation of the shift schedule optimization module, and these shift schedules are stored in the shift schedule database of the TCU. During the running of the vehicle, the signal...

Abstract

An automobile stepped automatic transmission multi-property comprehensive optimal shift decision making system is disclosed. A shift rule optimizing module off-line-calculates multi-property comprehensive optimal shift rules in different driving intentions, and stores the multi-property comprehensive optimal shift rules in a shift rule database; a signal acquisition module acquires automobile state information and driver operation information in a running process of the automobile in real time, and stores the automobile state information and the driver operation information in an automobile driving state database; a driving intention recognition module online-recognizes a shift property expectation of a driver, and quantizes the shift property expectation; a target shift decision making module selects or construct a shift rule on the basis of the shift rule database according to the shift property expectation quantized value, and determines a target shift; and a shift execution module completes a shift operation according to the target shift. The automobile stepped automatic transmission multi-property comprehensive optimal shift decision making system can optimize the power property, the fuel economy and the emission property of the automobile on the premise of embodying the driver shift property demand.

Description

technical field [0001] The invention relates to the electronic control technology of an automatic transmission for automobiles, in particular to a multi-performance comprehensive optimal gear decision system for a stepped automatic transmission for automobiles. Background technique [0002] Automotive stepped automatic transmissions include hydraulic automatic transmissions (AT), electromechanical automatic transmissions (AMT) and dual-clutch automatic transmissions (DCT) with a fixed number of gears. The gear decision system is used to determine the target gear of the stepped automatic transmission, and it is one of the key subsystems of the stepped automatic transmission control system. The existing gear decision-making system generally takes the accelerator opening and vehicle speed as the shift control parameters, and usually sets the shift schedule with the goal of optimizing a single performance index (such as the best power or the best economy), or uses the power The...
