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 for an automobile automatic transmission. Background technique [0002] Automobile automatic transmission is one of the core technologies of automobiles. The development of its electronic control unit (TCU) involves research in multiple disciplines and fields such as automobiles, electronics, computers, automatic control and dynamics. Contact is a complex system engineering. At present, the development of electronic control devices for automatic transmissions in my country is still in its infancy, but it is applied to actual vehicles in the form of products, and there are no relevant specific reports so far. The 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 tests, the results show that the electronic control device of the automa...
