Example Embodiment

[0067] Please refer to the attached drawings. The present invention provides an electronic control device for an automatic transmission of an automobile. The central processing unit CPU1 is connected to the analog input channel 2, the pulse input channel 3, and the digital input channel 4. The central processing unit CPU1 is also connected to the analog input channel 2, the pulse input channel 3, and the digital input channel 4. Digital output channel 5 and pulse output channel 6 are connected. The central processing unit CPU1 is also connected to the power supply module 8 and the CAN bus communication module 7. The central processing unit CPU1 controls the input signal, obtains the state information of the car, and shifts according to the memory Regularly, the output signal controls the shifting of the car.

[0068] The input signal of the analog input channel 2 is the throttle opening signal 22 and the gearbox oil temperature signal 21.

[0069] The input signal of the pulse inp...

Abstract

The invention relates to an electric controller of vehicle automatic speed changer, wherein the central processor CPU is connected to the analogue input channel, the impulse input channel, the digit input channel, the digit output channel, the impulse output channel, the power source module, and the CAN bus communication module; the central processor CPU controls the input signal to obtain the state information of vehicle, and output signal to control the shift of vehicle, according to the speed and the throttle open degree of memory; the central processor uses new high-speed chip, with high calculation accuracy and large capacity. The inventive controller can accurately read the input signal of carrier, to output control signal to drive the circuit to control the shift electromagnetic valve.

Description

Technical field [0001] The invention relates to an electric control device, in particular to an electric control device of an automatic transmission of an automobile. Background technique [0002] Automobile automatic transmission is one of the core technologies of automobiles. The development of its electronic control unit (TCU) involves multi-disciplinary and multi-field research such as automobiles, electronics, computers, automatic control, and dynamics. At the same time, it is also related to the engine control system. Connection is a complex system engineering. At present, the development of my country's automatic transmission electronic control device is still in its infancy, but it is applied to actual vehicles in the form of products, and there is no relevant specific report. The present invention proposes the development of an electronic control device for an automatic transmission of an automobile. Through a large number of actual measurement and comparison experiments...
