Embodiment 1

[0051] figure 1 It is a schematic flow chart of a cruise control method provided in Embodiment 1 of the present invention. This method is applicable to the situation where cruise control is performed during vehicle driving. Cruise control is entered when it is judged according to the vehicle driving information that the current cruise entry condition is met, and in According to the vehicle information, it is judged that when the current cruise exit conditions are met, the cruise exit can be achieved to achieve the effect of automatic cruise, and the problem of low safety and high cost caused by manually pressing the cruise switch to enter or exit the cruise can be solved. The method can be executed by a cruise control device, which can be implemented by software and / or hardware, and is generally integrated on a terminal, which can be an intelligent terminal with processing functions, such as a driving computer, a vehicle computer, and the like.

Abstract

The embodiment of the invention discloses a cruise control method, device, terminal and vehicle system. The cruise control method includes: according to the vehicle running information within a preset time period, judging whether the current cruise entry condition is met; wherein, the vehicle running information includes the accelerator pedal opening and the vehicle speed; if so, entering the cruise control; according to the current vehicle information, Judging whether the cruise exit condition is currently satisfied; wherein, the vehicle information includes vehicle driving information, brake pedal information, and clutch pedal information; if so, exit the cruise control. The technical solution provided by the embodiment of the present invention can automatically enter or exit the cruise without depending on the cruise control switch, which improves the driving safety and saves the cost at the same time.

Description

technical field [0001] The embodiments of the present invention relate to the technical field of cruise control, in particular to a cruise control method, device, terminal and vehicle system. Background technique [0002] Cruise control system (cruising control system) referred to as CCS. Using electronic technology, within a certain speed range, the driver does not need to control the accelerator pedal, but an electronic control device that can ensure that the car runs stably at a set speed. When a car equipped with this device is driving on the highway, it can save the driver's frequent stepping on the accelerator and automatically maintain the preset speed, thereby greatly reducing the driver's fatigue and improving driving stability. performance, safety, comfort and fuel economy. [0003] At present, a cruise switch is usually provided on the vehicle. When the driver presses the cruise switch, he can enter the cruise control, and when he presses the cruise switch again...
