Problems solved by technology

Sometimes, only changing the speed of the vehicle cannot achieve the purpose of ensuring the driving safety of the vehicle. For example, when a vehicle behind the vehicle suddenly approaches, overtakes or changes lanes to overtake, whether the vehicle needs to actively change lanes to avoid and which side to change lanes Avoidance, etc., the existing automotive active safety system cannot give clear instructions, so it cannot effectively guarantee driving safety
In short, the existing technology cannot guide the driver to a safe driving path based on the real-time tracking of the surrounding conditions.

Embodiment 1

[0036] This embodiment provides an automobile active safety system, see figure 1 , the system is as follows:

[0037] The detection module 101 is used to detect the distance and relative speed between the vehicle and surrounding objects;

[0038] An analysis module 102, configured to compare the value detected by the detection module with a preset value, and analyze to obtain a driving strategy, wherein the driving strategy includes a predicted driving speed and driving direction;

[0039] The execution module 103 is configured to control the operation of multiple control devices on the vehicle according to the driving strategy.

[0040] The system provided in this embodiment, by detecting the distance and relative speed between the vehicle and the surrounding objects, compares the value detected by the detection module with the preset value, analyzes and obtains the driving strategy, and the driving strategy includes the predicted driving speed and driving speed. Direction,...

Embodiment 2

[0042] This embodiment provides an automobile active safety system, see figure 2 , the system is as follows:

[0043] A detection module 201, configured to detect the distance and relative speed between the vehicle and surrounding objects;

[0044] Wherein, the detection module 201 includes a plurality of on-board sensors for detecting distances and relative speeds between the vehicle and surrounding objects in front, rear, left, and right directions of the vehicle. The surrounding objects include stationary objects and moving objects around the vehicle. The detection module 201 in the embodiment of the present invention includes six vehicle-mounted sensors, which are respectively located at the front, rear, left front, left rear, right front and right rear of the vehicle. Of course, the user can also install more sensors for real-time tracking of the surrounding conditions of the vehicle, and the embodiment of the present invention does not limit the number and installation...

Embodiment 3

[0063] This embodiment provides an automobile active safety method. see Figure 4 , the method flow provided by this embodiment is specifically as follows:

[0064] 301: Detect the distance and relative speed between the vehicle and surrounding objects;

[0065] Specifically, the distance and relative speed between the object and the vehicle in the front, rear, left, and right directions of the vehicle are detected. For example, six on-board sensors can be installed at the front, rear, left front, left rear, right front and right rear of the vehicle to detect the distance and relative speed between the vehicle and surrounding objects. Of course, the user can also install more sensors for real-time tracking of the surrounding conditions of the vehicle, and the embodiment of the present invention does not limit the number of sensors.

[0066] Wherein, the vehicle-mounted sensor specifically includes: a vehicle-mounted radar device, a vehicle-mounted laser radar device, an inf...

Abstract

The invention discloses an active safety system and an active safety method of a vehicle and belongs to the field of vehicle safety. The system comprises a detection module, an analysis module and an execution module, wherein the detection module is used for detecting a distance between the vehicle and a surrounding object, and a relative speed; the analysis module is used for comparing a detected value of the detection module with a preset safety distance value and analyzing to obtain a traveling policy; the traveling policy comprises a pre-determined traveling speed and pre-determined traveling direction; and the execution module is used for controlling a plurality of control devices on the vehicle to operate according to the traveling policy. The method comprises the following steps of: detecting the distance between the vehicle and the surrounding object, and the relative speed; comparing the detected value with the preset value and analyzing to obtain the traveling policy, wherein the traveling policy comprises the pre-determined traveling speed and the pre-determined traveling direction; and controlling the plurality of control devices on the vehicle to operate according to the traveling policy. The invention has the advantage that: by guiding a user to a safe traveling road, the driving safety of the user is improved.

Description

technical field [0001] The invention relates to the field of automobile safety, in particular to an automobile active safety system and method. Background technique [0002] With the development of society, the production of automobiles has increased year by year, but with the increase in the number of automobiles, the safety problems of automobiles have become more and more prominent. In the prior art, the driving safety of the vehicle is mainly controlled by the active safety system of the vehicle, which mainly ensures the driving safety by braking, decelerating or accelerating in the driving direction. [0003] In the process of realizing the present invention, the inventor finds that the prior art has at least the following disadvantages: [0004] The existing technology only ensures the driving safety of the vehicle by changing the speed of the vehicle in the driving direction, such as outputting control commands to an ECU (Electronic Control Unit, electronic control u...
