Automatic gear box control method and device

Abstract

The invention relates to a control method and a device of the automatic gear shifting of automobiles, which discloses an electric control device of self-changing gearbox. A control unit comprises a main controller and a subordinate controller which connect together, and the main controller and the subordinate controller receive signals of a sensor through a signal processor and input the signals through a switch signal input end. The main controller outputs the signals to a starting relay, a gear display, a buzzer and an external sensor through the signal processor, carries out data exchange with an electronic control unit through a bus module and is connected with the external equipment through a K line module. Signals output of the main controller and the subordinate controller are transferred to a signal output processor which is connected with a hydraulic operating system, and a clutch and a gear box are connected with the hydraulic operating system. The utility model has the advantage that under the circumstances of the failure of the main controller, the subordinate controller replaces the main controller, so that the traffic safety is ensured.

Description

technical field [0001] The invention relates to a method and a device for controlling an automatic transmission of an automobile, in particular to a method and a device for controlling an automatic transmission. Background technique [0002] With the original mechanical transmission and clutch unchanged, AMT replaces the manual operation of clutch separation, engagement, gear removal and suspension, and engine corresponding synchronous adjustment by installing an automatic control mechanism controlled by a microcomputer. Finally, the automation of the whole process of gear shifting is realized. [0003] At present, most of the electronic control units of automatic transmissions on the market are realized by a main controller. According to the change of the driving environment, the driver expresses the intention to the main control chip by operating the multi-functional lever gear selector, the accelerator pedal and the brake pedal (the clutch pedal is canceled) that reflect...

Problems solved by technology

However, the disadvantage of this method is that it is not safe. When there is a problem with the main control chip, the gear control signal and the clutch control signal will be confused, the gearbox is easily damaged, and even cause traffic accidents when driving.
