A car cruise control method, device, system and vehicle

Abstract

The invention discloses an automobile cruise control method, an automobile cruise control device, an automobile cruise control system and an automobile, relating to the technical field of automobile electronic control and solving the problem that the automobile cruise driving has poor safety. The automobile cruise control method comprises the steps of acquiring the constant time of cruising speed, when the constant time of the cruising speed is longer than or equal to the first setting time, determining that the automobile enters a single cruising speed state and running at single cruising speed; acquiring single cruising speed duration when the automobile is in the single cruising speed state; when the single cruising speed duration is longer than or equal to the second setting time, outputting a control signal enabling the automobile to exit the cruising status, so as to enable the automobile to exit the cruising status, and giving a sound alarm to remind a driver that the automobile exits the cruising status. The automobile cruise control device and the automobile cruise control system comprise the control method provided by the technical scheme; the automobile cruise control method, the automobile cruise control device and the automobile cruise control system are used for improving the automobile cruising driving safety.

Description

technical field [0001] The invention relates to the technical field of automobile electronic control, in particular to an automobile cruise control method, device, system and vehicle. Background technique [0002] With the continuous development of automobile electronic control technology, cruise control system has been widely used in automobile driving system. Most of the existing cruise control systems are constant speed cruise systems. During the driving process of the car, the driver sets the cruise speed by adjusting the switch, and the vehicle enters the cruise state or exits the cruise state through the cruise switch. When the car is set to In the cruising state, the fuel supply of the engine is controlled by the electronic control unit (hereinafter referred to as ECU), so that the car can run at a constant speed, reducing unnecessary speed changes, thereby saving fuel consumption and improving driving comfort. [0003] However, the inventors of the present applicati...

AI Technical Summary

Problems solved by technology

[0003] However, the inventors of the present application have found that a large amount of actual vehicle driving tests are statistically summarized, because the vehicle exits the cruising state and is realized by the driver, when the vehicle is cruising for a long time with a single speed (constant speed), because the driver does not need to When operating and controlling the vehicle, it is easy for the driver to lose concentration or fall asleep, which is prone to traffic accidents and affects the safety of cruising driving

Although currently some cars are equipped with a driving reminder system to remind the driver, the risk of traffic accidents will also increase due to the fast cruising speed and untimely exit from the cruising state; Potential safety hazards, affecting the safety performance of vehicle cruise driving
