Prototype controller used for automatic speed-change control and complete power distribution

Abstract

The invention discloses a prototype controller used for automatic speed-change control and complete power distribution, which is characterized by comprising a main control chip, a power supply module, a switch value processing module, an analog value processing module, a Hall signal processing module, a magneto-electric signal processing module, a communication module, a constant-current low-end switch driving module, a high-end switch driving module, a relay low-end switch driving module and a low-end switch driving module. The main control chip is connected with the power supply module, the switch value processing module, the analog value processing module, the Hall signal processing module, the magneto-electric signal processing module, the communication module, the constant-current low-end switch driving module, the high-end switch driving module, the relay low-end switch driving module and the low-end switch driving module respectively. The prototype controller utilizes the product-level main control chip and has common driving capacity, and the load capacity of the finished product controller to the control algorithm can be focused and checked at the prototype control stage.

Description

technical field [0001] The invention relates to the field of automobile control, in particular to a prototype controller for automatic speed change control and vehicle power distribution. Background technique [0002] On the one hand, with the improvement of people's requirements for car comfort, the equipment rate of automatic transmissions in automobiles is also increasing, especially when automatic transmissions are gradually able to take into account the handling. The types of automatic transmissions include AT (hydraulic automatic transmission), CVT (continuously variable transmission), DCT (dual clutch transmission), AMT (automatic mechanical transmission), and the like. The technology of automatic transmission has become a competitive weapon among manufacturers, and domestic automakers and research institutes are paying more and more attention to the development of automatic transmission control devices. [0003] On the other hand, with the global energy crisis and t...

AI Technical Summary

Problems solved by technology

[0005] The prototype controller in the prior art has a powerful micro control unit (Micro Control Unit, MCU) and very rich hardware interface resources, which can meet the needs of most controllers in the automotive field, but its disadvantage is that the prototype The controller does not have signal conditioning and power drive capabilities, and must be used together with the supporting drive device, which is expensive, bulky, and inconvenient to use

Not only that, the main frequency of the prototype controller MCU reaches 800MHz, which is quite different from the processing capability of the MCU used in general automotive controllers (the performance is much higher than the actual automotive controller MCU), so the prototype controller is used to verify the algorithm There is no way to assess the load capacity and real-time performance of the final product controller for these control algorithms
