Abstract

The invention provides a device for realizing the coordination and matching of interaction between an automatic mechanical transmission (AMT) system of automobile electronics and an electronic control engine by an electronic throttle splitting line. The coordination and matching of interaction between the control unit of the existing electronic automatic transmission system (DCU) and the controller of the electronic control engine (ECU) is implemented through CAN bus communication or other ways of communication, and the operation of the finished automobile is controlled and coordinated by the electronic control engine side according to the running state of the electronic automatic transmission side and the request, thus realizing the unified control of the power assembly. The invention has the beneficial effects of effectively realizing the effective coordination and matching control of the AMT to the ECU of the engine, realizing the control of the power assembly in an AMT initiative mode in which the AMT is taken as the main part, ensuring the initiative of the AMT on the matching to various electronic control engines, accelerating the expansion of development space of the AMT, and simultaneously effectively achieving the reset function of power failure, and ensuring the safety of each part due to the adoption of the electronic throttle splitting line.

Description

A kind of electronic throttle splitting line

Technical field

The present invention is that mechanical type automotive electronics automatic speed-changing system (is called for short: AMT), realize the device that the dialogue coordination is mated with electric-control motor by electronic throttle splitting line.

Background technique

(be called for short: DCU), and the controller of electric-control motor (is called for short: the dialogue coordination coupling ECU) control unit of present electronic automatic speed system.Be to be undertaken by CAN bus communication or other communication way, control to the car load operation is coordinated according to the running state and the request control of electronic automatic transmission side by electric-control motor side, realize the unified control of power assembly, in case motor side will not cooperate, automatic transmission side can't with Engine Matching, this is maximum technology barriers concerning a side who does not grasp the engine core technology.

Summary of the invention

In order to make the initiative of motor to electronic automatic speed system coordination coupling, forward to by the electronic automatic speed system and directly motor relevant matches parameter is controlled coordination, realize the control of whole power assembly.The present invention adopts and passes through electronic throttle splitting line, requirement with the electronic automatic speed system, cutting signal by gearbox DCU output, driving pulse 1, pulse 2 deciphering cutting contacts, analog amount cutting contact, the coherent signal cutting of efp is arrived in the gearbox DCU treated analog quantity channel and the pulse passage of delivering to Engine ECU by the cutting contact; After handling from the signal cutting of E-Gas to AMT ECU (Electrical Control Unit) DCU, by signal cutting contact, cut off the contact of efp analog amount and pulse 1 and pulse 2 output terminals simultaneously to Engine ECU, deciphering electric-control motor throttle channel, deliver to engine electric-controlled unit ECU by the electricity-controlling throttle passage again, realize motor is coordinated the control of coupling; The control unit DCU of AMT control two-way relay, the one tunnel is responsible for cutting, promptly directly connects Engine ECU from E-Gas, and cutting sends to the DCU of AMT to E-Gas, send Engine ECU after the processing again; One the tunnel is responsible for deciphering, decipher the pulse signal that control end sends by gearbox DCU, control deciphering relay goes to drive the deciphering contact, by pulse passage Engine ECU is sent decrypted signal, for the control unit DCU of AMT coordinates to clear away passage to the control of control unit of engine ECU, the positive and negative electrode of cutting simultaneously, by 0V current potential cutting contact and 5V cutting contact and 0V shielding wire, contacting directly mutually of the power supply of switching gearbox DCU and Engine ECU, effectively the power supply to Engine ECU and speed changer DCU carries out isolation processing.

The invention has the beneficial effects as follows, because after adopting electronic throttle splitting line, effectively realized of the effective coordination coupling control of AMT part to Engine ECU, realize the AMT active mode of the control of power assembly based on the AMT aspect, guaranteed the initiative of AMT, accelerated to have enlarged the development space of AMT, effectively Engine ECU and speed changer DCU have been carried out isolated from power simultaneously various electric-control motor couplings, effectively realize the power-off restoration function simultaneously, guaranteed Security separately.
