Air-conditioning pump motor control unit of electric vehicle

Abstract

The invention relates to an air-conditioning pump motor control unit of an electric vehicle. The air-conditioning pump motor control unit is characterized in that a strong-light detector is connected with a motor controller, a Hall sensor is connected with a direction system steering controller, a photosensitive detector is connected with an ambient light intensity regulator, a closing regulator is connected with an illumination light source, signals which are respectively outputted by the motor controller, the direction system steering controller, the ambient light intensity regulator and the illumination light source are transmitted to a driving amplifier via an A / D (analog / digital) input interface, a microcomputer and a D / A (digital / analog) output interface, and the driving amplifier is in control connection with high and low-beam lamps, a special steering lamp, a position lamp and a reflector. The air-conditioning pump motor control unit has the advantages that the microcomputer controls on-off and switching of the warning position lamp, the high and low-beam lamps and the steering lamp of the vehicle in real time on the basis of a combination of input of ambient light intensity, meeting, overtaking and road strong-light signals of the vehicle and input of detection signals of a steering system turning angle and an illumination angle of the illumination light source, dynamic follow-up integral lamp light control is implemented, and the air-conditioning pump motor control unit is high in vehicle lamp light automatic control degree and intelligent precision and quick in electronic response.

Description

technical field [0001] The invention relates to a motor control unit of an electric car air conditioner pump. Background technique [0002] At the beginning of this century, Japan's Denso Corporation took the lead in applying advanced electronics, computers, sensing and software control technologies to launch the DHL lighting follow-up controller, which is applied to high-end cars and commercial vehicles, which not only significantly improves the safety performance of vehicle lighting systems, but also enables Vehicle engineering technology presents the development trend of electronization, intelligence and automation. [0003] At present, the application scale of automotive lighting follow-up control systems in developed countries has increased from more than 1 million sets in 2002 to more than 32 million sets in 2010. Control System. With the increasingly severe situation of global automobile traffic safety, countries all over the world have increased the promotion and a...

AI Technical Summary

Problems solved by technology

The technical status of the industry has the following defects: 1. Lamp manufacturers and automobile manufacturers have not yet formed an integrated development framework, and it is difficult to form an overall competitive advantage in the lighting dynamic follow-up system for independent operation; 2. The lighting system for automobiles alone, The quality level is low, there are defects such as low precision, poor reliability, easy loosening, light switching, switching, and angle adjustment are all manual, and complicated operation and control, which weakens the safety performance and core competitiveness of domestic vehicles.
