Problems solved by technology

From the perspective of market demand and the development trend of safety, environmental protection and energy-saving products, the development of AMT technology, especially the development of core technology controllers, is very realistic for improving the technical content of automotive products and strengthening their competitiveness. However, the current domestic AMT system in China Most of the controllers are imported from abroad, the cost is high, and the structure is relatively complicated. At the same time, the controller of the domestic AMT system mainly controls the valve, and the controlled object is the motor. It is still immature or still in the research stage.

Abstract

The invention belongs to the vehicle control unit field. The vehicle control unit comprises a central processor; the central processor is connected with a power source module, an analog quantity acquisition module, a switching quantity acquisition module, a frequency quantity acquisition module, a low-end driving module, a motor control module, a motor current-detection module and a CAN communication module through signal lines respectively. According to the vehicle control unit, acquired signals are processed through the analog quantity acquisition module, the switching quantity acquisition module and the frequency quantity acquisition module; processed signals are transmitted to the central processor; the central processor communicates with a vehicle CAN communication module through the CAN communication module; the electric loads of relays work according to requirements under the control of the central processor; the motor control module can realize gear selection and gear shift under the control of the central processor; and therefore, the vehicle control unit can obtain the running state of a vehicle at any time in a driving process and accurately acquire the operating information of a driver, and analyzes the operating conditions of various components of the vehicle, so as to coordinate the actions of various mechanisms. The vehicle control unit has the advantages of simple structure, safety and reliability, and can assist in reducing cost.

Description

technical field [0001] The invention relates to the field of vehicle control technology in vehicle electronic control technology, in particular to a vehicle controller. Background technique [0002] At present, there are three main types of automobile automatic transmissions that are most used in the world: the first is hydraulic automatic transmission, referred to as AT; the second is electronically controlled mechanical automatic transmission, referred to as AMT; the third is mechanical stepless automatic transmission. Transmission, referred to as CVT; Among them, AMT has been welcomed by major automobile manufacturers since the 1980s due to its high transmission efficiency, compact mechanical structure, and reliable operation, and its research is also gradually heating up. The core of the AMT development technology is the software and hardware development of the gearbox controller to achieve strong consistency, high flexibility, and comfort for passenger cars, and take in...
