Embodiment Construction

[0016] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0017] like figure 1 As shown, the car cruise control system includes a central processing unit, an accelerator pedal, a brake pedal, a clutch pedal and a throttle. The central processing unit is connected with the throttle and the engine at the same time. Controllable valve, mixed with gasoline after entering the intake pipe. The central processing unit can control the opening degree of the throttle valve and can time the duration of the throttle valve being kept at a certain opening degree, and the central processing unit can also constantly detect the output power of the engine.

[0018] When the car is running stably at a certain speed, the opening of the throttle remains unchanged, and the central processing unit will time...

Abstract

The invention provides an auto cruise control system, which belongs to the technical field of cruise control and solves the problem that the traditional auto cruise control function is required to be started manually. The auto cruise control system disclosed by the invention comprises a central processing unit, an interrupting device and a feedback device, wherein the feedback device can reflect the speed state of an automobile; the central processing unit is connected with the feedback device and an engine throttle and can control the opening size of the throttle; the feedback device feeds the feedback information indicating the speed of the automobile back to the central processing unit; after detecting that the speed of the automobile is in a stable state according to the feedback information, the central processing unit enters a cruise control state and controls the throttle to keep the opening size; and the automobile can be interrupted by the interrupting device after entering the cruise control state. The auto cruise control system provided by the invention has the advantages of automatically entering a cruise control state according to the stability of the speed of the automobile, thereby simplifying the operation of a driver, reduce driving fatigue, reducing unnecessary speed change, and saving fuel.

Description

technical field [0001] The invention belongs to the technical field of cruise control and relates to a cruise control system for automobiles. Background technique [0002] Cruise control system (CRUISE CONTROL SYSTEM) is abbreviated as CCS, also known as cruise control device, speed control system, automatic driving system, etc. Its function is: after the switch is closed according to the speed required by the driver, the speed of the vehicle will be automatically maintained without stepping on the accelerator pedal, so that the vehicle can run at a fixed speed. Then go to control the accelerator pedal, reduce driving fatigue, reduce unnecessary speed changes at the same time, can save fuel. [0003] The speed control of the car is realized by the driver constantly stepping on or relaxing the accelerator pedal, adjusting the opening of the throttle valve, and controlling the output power of the engine while the car is running. Once the car is set to cruise, the fuel supply...
