Embodiment Construction

[0044] As mentioned above, when other vehicles cut into the front of the vehicle in the current lane of the vehicle, the existing adaptive cruise control system has certain limitations, which is mainly manifested in: the vehicle suddenly decelerates during the crossing process , causing interference to the surrounding normal driving vehicles and thus easily causing traffic accidents, and secondly, the sudden deceleration of the vehicle makes the driver feel uncomfortable.

[0045] In view of the above problems, an embodiment of the present invention provides a vehicle adaptive cruise control method. The method detects that the vehicle to be cut into the adjacent lane sends a signal to cut into the current lane, and according to the motion information of the vehicle to be cut into Calculate the second acceleration of the vehicle, and calculate the updated acceleration of the vehicle according to the current acceleration of the vehicle and the second acceleration, so as to gradua...

Abstract

The invention relates to a vehicle adaptive cruise controller, a method and a system; the method comprises the following steps: monitoring a wait-to-cut in vehicle on an adjacent lane to send a signal of cutting into the present lane; calculating a second acceleration speed of the self vehicle according to the motion information of the wait-to-cut in vehicle; calculating an updated acceleration speed of the self vehicle according to the present acceleration speed and the second acceleration speed; adjusting the self vehicle speed according to the calculated updated acceleration speed. The method allows the self vehicle to gradually adjust the speed in a process in which the wait-to-cut in vehicle cuts into the present lane, thus preventing self vehicle from suddenly changing speed, reducing traffic accidents caused by sudden changes of the speed, and removing driver discomfort.

Description

technical field [0001] The invention relates to the technical field of vehicle safety, in particular to a vehicle adaptive cruise controller, method and system. Background technique [0002] Adaptive cruise control (Adaptive Cruise Control, ACC) is a car function that allows the vehicle cruise control system to adapt to traffic conditions by adjusting the speed. It is mainly used to improve driving safety. The control technology of adaptive cruise control system is getting more and more attention. [0003] In the prior art, the adaptive cruise control system mainly detects whether there is a vehicle on the road ahead of the vehicle, and actively decelerates to control the reasonable distance between the vehicle and the vehicle in front when there is a vehicle ahead. Drive at the speed set by the driver. However, the existing adaptive cruise control system has certain limitations when other vehicles cut into the road ahead of the vehicle. Interference thus easily causes tra...
