Problems solved by technology

Conventional adaptive cruise control can only achieve longitudinal control of the vehicle, but in terms of lateral control, the driver still needs to control the vehicle for steering operations
In the process of changing lanes, if the driver does not observe the surrounding vehicle environment carefully enough, accidents such as vehicle collisions may occur, resulting in low driving safety of the vehicle, and at the same time reducing the driving experience of the driver, which is not conducive to the above-mentioned adaptive cruise system on the vehicle. promotion and application of

Embodiment

[0017] Example: such as figure 1 As shown, a calculation method for car intelligent assisted driving lane change warning, the adaptive cruise system is activated when the car is moving, which frees the user's hands and feet while enhancing the user's experience. The above-mentioned car intelligent assisted driving lane change warning The calculation method includes the following steps:

[0018] Step a, first set a safe distance in the adaptive cruise system, that is, a safe distance between the front vehicle and the rear vehicle suitable for the main vehicle to change lanes;

[0019] Step b. When the main vehicle is changing lanes or is about to change lanes, respectively estimate the distance between the front vehicle and the rear vehicle on the target lane, and the target lane is the lane where the main vehicle is about to change lanes;

[0020] Step c. When the estimated distance between the front vehicle and the rear vehicle on the target lane is less than the set safety ...

Abstract

The invention relates to a calculation method for intelligent auxiliary driving lane changing early warning of an automobile. The calculation method comprises the following steps: a, setting a preset safety distance in an automobile intelligent auxiliary driving lane changing system; b, when the main vehicle changes the lane or is about to change the lane, estimating the distance between the front vehicle and the rear vehicle on the target lane; and c, when the distance between the front vehicle and the rear vehicle on the estimated target lane is smaller than the preset safe distance, sending out warning information, and meanwhile forbidding lane changing operation; and when the distance between the front vehicle and the rear vehicle on the estimated target lane is greater than a set safety distance, carrying out lane changing operation. According to the calculation method for intelligent auxiliary driving lane changing early warning of the automobile, occupied calculation resources are low, it can be guaranteed that data are updated in real time in the automobile speed changing process, safety can be improved, real-time performance can be guaranteed, meanwhile the calculation method can be combined with other intelligent auxiliary driving technologies to form a more intelligent and effective function, and user experience is enhanced.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a calculation method for lane-changing warnings for intelligent assisted driving of automobiles. Background technique [0002] Adaptive cruise can also be called active cruise, similar to traditional cruise control, the system includes radar sensors, digital signal processors and control modules. In the adaptive cruise system, the system uses low-power radar or infrared beams to obtain the exact position of the vehicle in front. If it finds that the vehicle in front slows down or detects a new target, the system will send an execution signal to the engine or braking system to reduce the speed of the vehicle, thereby Keep a safe driving distance between the vehicle and the vehicle in front. When the obstacles on the road ahead are cleared, it will accelerate back to the set speed, and the radar system will automatically monitor the next target. The active cruise control syst...
