Embodiment Construction
[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0030] The core of the present invention is to provide a constant speed cruise control method and control device. The control method and control device can quickly and stably adjust the vehicle speed to reach the cruise target vehicle speed when the vehicle cruise target speed is inconsistent with the actual vehicle speed.
[0031] Another core of the present invention is to provide a vehicle including the above constant speed cruise control device.

The invention discloses a control method and control device of cruise control. The control method comprises acquiring a current actual speed of a vehicle and a cruise target speed set currently, determining whether the current actual speed is greater than the cruise target speed, and sending a braking signal to a braking system and allowing the braking system to make a braking operation according to the braking signal if the current actual speed is greater than the cruise target speed. The control method controls the braking system for braking by controlling program logic and enables the braking in a cruise control process to be achieved automatically. The braking process is actively achieved through the braking system, so as to realize the deceleration in a cruise control state, and the braking process is more efficient and stable and does not damage the program logic of the cruise control. The invention also discloses the vehicle comprising the control device of the cruise control. The vehicle can quickly and stably perform a brake control operation in the cruise control state and can keep the cruise control state.
Description
technical field [0001] The present invention relates to the technical field of vehicle control, and more specifically, to a constant speed cruise control method and control device. In addition, the present invention also relates to a vehicle comprising the above constant speed cruise control device. Background technique [0002] With the development of automobile electronic control, the cruise system has become one of the more common technologies in the automatic control of vehicles. Among them, constant speed cruise and adaptive cruise are methods for controlling vehicles to run at a constant speed. [0003] In the current cruise control function, when the cruise target vehicle speed is lower than the actual vehicle speed, the vehicle control can only rely on the two measures of engine oil cut-off and torque converter lock-up to make the vehicle reverse the engine for slow braking. However, the braking speed of these two measures is relatively slow, and the vehicle speed c...
