Abstract

The invention discloses a self-adaptive cruise control system of a vehicle. The self-adaptive cruise control system comprises a self-adaptive cruise sensing and controlling device, and a FlexRay bus which is connected with the self-adaptive cruise sensing and controlling device, an engine management system, a transmission control unit, an electronic stability program unit and an instrument unit. The self-adaptive cruise control system disclosed by the invention can be used for enhancing the response speed of an ACC (adaptive cruise control) system, and improving the sensitivity and safety of cruise driving.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an adaptive cruise control system for vehicles. Background technique [0002] With the increasing electronic degree of automobiles, there are more and more wiring harnesses on automobiles. Due to the control of manufacturing costs by car manufacturers and the control of body quality, reducing wiring harnesses has become a problem that must be solved. There are many types of vehicle communication networks, and the most widely used are LIN (Local Interconnect Net-work, local interconnection network), CAN (Controller Area Network, controller area network), FlexRay, ASRB (Automotive Safety Restraints Bus, automatic safety restriction Bus), MOST (Media Oriented System Transport, Media Oriented System Transport) and so on. The Society of Automotive Engineers (SAE) divides automotive communication networks into three categories: A, B, and C according to the speed. Type A includes...
