Automatic transmission automobile motion pattern adjusting device and method

Abstract

The invention discloses an automatic transmission automobile motion pattern adjusting device and method, and relates to the field of automobile motion pattern designing. The device comprises a manual adjustment device body and a controller, wherein the manual adjustment device body stays in the corresponding control states through manual adjustment of a driver, the controller is used for storing different transmission shifting moment control charts and selecting the transmission shifting moment control charts corresponding to the control states to serve as the transmission shifting moment control charts when an automobile is in the motion pattern. The transmission shifting moment control charts are used for providing the engine speed under different accelerator openings when different transmission shifting motions are executed. According to the automatic transmission automobile motion pattern adjusting device, the motion patterns can be flexibly adjusted, and therefore the driver can give consideration to both the automobile dynamic property and the fuel consumption performance.

Description

technical field [0001] The invention relates to the field of automobile motion mode design, in particular to a device and method for adjusting the motion mode of an automatic transmission automobile. Background technique [0002] At present, automatic transmission cars generally have a sports mode. When the driver switches the shift lever to the S position, the sports mode starts, at this time, the timing of the shift is delayed, the engine torque output increases, and the power of the engine improves. [0003] In normal mode, the controller stores the universal characteristic curve of the engine (see figure 1 ) and the pedal-torque table (see Table 1). [0004] [0005] Table 1 [0006] exist figure 1 Among them, the abscissa is the engine speed, the ordinate is the output torque (the left ordinate / Nm) and the fuel consumption rate (the number g / kW·h marked by the curve in the figure), indicating the fuel consumption of the engine at different speeds and torques . ...

AI Technical Summary

Problems solved by technology

[0018] Compared with the normal mode, the sports mode not only improves the power of the car, but also increases the fuel consumption, and sometimes the driver only needs the power of the car to be improved compared with the normal mode, and does not need to be improved to the extreme of the sports mode The degree of fuel consumption; however, under the existing technical conditions, the driver can only choose whether to use the sports mode, and cannot freely adjust the sports mode according to his needs
