Embodiment 1

[0050] figure 2 It is a structural block diagram of the cruise control device provided by the embodiment of the present invention, please refer to figure 2 , the cruise control device provided in this embodiment includes the following modules:

[0051] The constant speed cruise module 1 is used to receive and adjust the constant speed cruise target vehicle speed according to the operation signal input by the user;

[0052] The speed acquisition module 2 is configured to continuously acquire the actual vehicle speed and the cruise control target vehicle speed of the vehicle at predetermined time intervals, so as to ensure the timeliness of acquiring the actual vehicle speed and the target vehicle speed.

[0053] Difference calculation module 3, used to calculate the difference between the actual vehicle speed and the target vehicle speed;

[0054] a strategy determination module 4, configured to compare the magnitude of the difference with the first preset threshold and the s...

Abstract

The invention discloses a constant speed cruising device, comprising a constant speed cruising module, which is used for receiving and adjusting a constant speed cruising target vehicle speed according to an operation signal inputted by a user; A speed acquisition module configured to continuously acquire the actual vehicle speed and the constant speed cruise target vehicle speed of the vehicle atpredetermined time intervals; A difference calculation module, configured to calculate a difference between the actual vehicle speed and the target vehicle speed; A strategy determination module, configured to compare a difference value with a first preset threshold value and a magnitude of a second preset threshold value, and determine a display strategy for displaying a vehicle speed accordingto the comparison result; The display module is configured to display the display vehicle speed according to the display strategy determined by the policy determination module. The invention also discloses a vehicle. The invention solves the phenomenon of display vehicle speed jitter caused by bump or road condition of uphill and downhill under the constant speed cruising state, and also avoids the phenomenon of display vehicle speed drop when the constant speed cruising target vehicle speed is continuously and quickly set. The invention also solves the problem of display vehicle speed jittercaused by road condition of uphill and downhill.

Description

technical field [0001] The invention relates to the technical field of intelligent driving, in particular to a cruise control device and a vehicle. Background technique [0002] In the constant speed cruise state, the vehicle will automatically maintain a fixed speed at the set target speed, and the speed of the vehicle will be displayed to the driver through the speedometer. Normally, the displayed speed of the instrument is the same as the actual speed of the vehicle, but when the vehicle encounters bumps or uphill or downhill road conditions, due to the vehicle's own weight, it is impossible for the vehicle to maintain a constant speed. The speed of the vehicle will change accordingly, which is manifested as pointer jitter (pointer instrument) or digital beating (digital instrument). The driver will feel that the speed displayed by the speedometer is inconsistent with the set target speed, which will bring poor driving experience to the user. experience. In order to sol...
