Fuel saving device and fuel saving method applied to adaptive cruise system

Abstract

The invention provides a fuel saving device and a fuel saving method applied to an adaptive cruise system, belonging to the technical field of vehicles. The device comprises a navigation system, a camera, an image processing unit and an adaptive cruise system control unit, wherein the navigation system is used for providing route information and intersection location information for adaptive cruise of a vehicle; the camera is used for collecting image information of intersection traffic lights; the image processing unit is used for processing the image information so as to judge the information of the intersection traffic lights; and the adaptive cruise system control unit is used for collecting the route information, the intersection location information, the information of the intersection traffic lights and vehicle information, and judging a power output requirement of the vehicle according to the route information, the intersection location information, the information of the intersection traffic lights and the vehicle information so as to control the vehicle to pass through the intersection. The fuel saving device and the fuel saving method provided by the invention make use of dragging of an engine to the utmost extent to reduce the speed and reduce brake intervention as far as possible, can also improve comfort for passengers, and can effectively reduce the fuel consumption of the vehicle using the adaptive cruise system in urban areas.

Description

technical field [0001] The invention relates to the technical field of vehicles, in particular to a fuel-saving device and method for an adaptive cruise system. Background technique [0002] The adaptive cruise system is an intelligent automatic control system, which is developed on the constant speed cruise control system. During the driving process of the vehicle, the vehicle distance sensor (radar) installed in the front of the vehicle continuously scans the road conditions in front of the vehicle. If there is a target vehicle in front and the vehicle speed is lower than the cruise speed set by the own vehicle, the adaptive cruise system will combine the information of the vehicle ahead detected by the radar with the vehicle speed signal provided by the wheel speed sensor to calculate the time required for collision with the front vehicle, if the calculated value is less than When the system sets the threshold, the adaptive cruise control unit will reduce the torque thro...

Problems solved by technology

However, because adaptive cruise control involves frequent acceleration and braking when used in urban areas, it will cause increased fuel consumption, which is contrary to the current energy crisis and environmental protection concepts, which limits the promotion of adaptive cruise systems
