Double-MCU automatic transmission control system with quick gear shifting mode

Abstract

The invention provides a double-MCU automatic transmission control system with a rapid gear shifting mode. A power supply module is respectively connected with a first MCU and a second MCU through a power supply management module, and the first MCU and the second MCU are connected through a serial bus; the two MCUs are combined into an automatic transmission control system, and when the dual-core MCU performs control in a serial bus mode, the auxiliary MCU can strengthen collection of various most critical analog signals and motor driving in the automobile driving process. Therefore, analog signals are prevented from being interfered, the motor is driven more accurately, and automobile driving is smoother and more comfortable. The vehicle automatic transmission is controlled through the double MCUs, signals are prevented from being interfered, the AMT transmission system does not have faults, each gear in the AMT transmission system corresponds to a gear shifting finger, the gear shifting time can be saved, and the pause feeling caused by gear shifting is avoided.

Description

technical field [0001] The present invention relates to a dual MCU automatic transmission control system with quick shifting mode. Background technique [0002] The existing vehicle AMT automatic transmission gear selection system and other control modules are controlled by a main control module. In many cases, the main control module needs to perform multiple information collection and processing actions of the transmission at the same time. Since it is completed by one controller, the controller It takes a certain amount of time to calculate, so there will be a short delay when the system processes and executes multiple task signals, and even the system may fail to cause the vehicle to lose control; [0003] In order to prevent the main control module from running under high pressure, many vehicle controllers use dual MCUs, such as a dual MCU electric vehicle controller with publication number CN108279610B, which is composed of two main and auxiliary MCUs, but it is aimed ...

Problems solved by technology

The steps of shifting gears can be summarized as retreating to neutral gear, the piston rod drives the sliding wall to select gears, the pull rod moves with the shift paddle, and the corresponding vertical shaft is pulled to shift gears. The operation steps are also three, although the other The accuracy of the hydraulic control piston is used to improve the accuracy of shifting, but there are too many transmission steps in the shifting process, the overall shifting process takes too long, the frustration still exists, and it is easy to cause the power of the vehicle during the shifting process. to interrupt
