Direct interface device for whole vehicle controller

Abstract

The invention relates to the technical field of automobile control, specifically a direct interface device for a whole vehicle controller, wherein the device is complete in function, is reasonable in structure, and is reliable in work. The device is characterized in that the device is provided with a digital interface circuit, an analog interface circuit and a relay interface circuit, wherein the digital interface circuit, the analog interface circuit and the relay interface circuit are respectively connected with the whole vehicle controller; the digital interface circuit is connected with a vehicle key position detection circuit, a gearbox position detection circuit and a circuit for detecting whether a brake is put into use or not. The analog interface circuit is connected with the whole vehicle controller through a power amplifier circuit. The analog interface circuit is connected with an accelerator pedal control circuit and a brake pedal control circuit. A relay connected with the relay interface circuit is an optical relay. Compared with the prior art, the device is reasonable in structure, is stable in operation, is long in service life, and is low in energy consumption.

Description

technical field [0001] The invention relates to the technical field of automobile control, in particular to a direct interface device for a complete vehicle controller with perfect functions, reasonable structure and reliable operation. Background technique [0002] Electric vehicles are made up of numerous electrical subsystems. It is the vehicle controller (VCU) that plays a leading and coordinating role. Information needs to be exchanged between the vehicle controller and each subsystem, and the information is divided into two categories: instructions and data states. There are two ways of exchange, one is direct and the other is indirect. The so-called direct way is the direct docking of information through the port; the so-called indirect way is the transmission of information through communication. The former is convenient, accurate, and highly reliable, but there are many interface wire harnesses, which are difficult to arrange and consume a lot of manpower and hour...

But its disadvantages are also obvious

First, the designer is not making enough fuss about the content, but is unconventional in the irrelevant form; second, the discreteness of accessories in the industry is accelerating, it is difficult to form a pillar industry, and the price is not easy to reduce; third, the quality of accessories is lacking. power
