Problems solved by technology

[0004] First of all, the sample size of the control parameters obtained in this way is small and cannot cover everyone's driving behavior and driving habits;
[0005] Secondly, during the development process of ACC / AEB, the developers calibrate the comfort and safety according to the acceleration, deceleration and braking force and other parameters of the test. Such parameters with a small sample size are completely unsuitable for every driver. driving habits;
[0006] Finally, a set of control parameters covers all driving behaviors, resulting in rough acceleration, deceleration and braking processes, resulting in uncomfortable and unpleasant driving. It is not suitable for everyone's driving habits and cannot achieve anthropomorphic driving.

Embodiment 1

[0088] refer to figure 1 , image 3 , the concrete scheme that the present invention adopts single sensor is:

[0089] The environmental perception module includes machine vision sensors (monocular camera, binocular camera and 3D camera), 77GHz millimeter-wave radar, lidar and car networking V2X.

[0090] If the system has only one of the above-mentioned sensors as a sensing device, the data collected by a single sensor is filtered, identified, tracked and identified as a dangerous target, and the speed, relative distance, acceleration, deceleration, azimuth and other related parameters of the dangerous target are sent to the Anthropomorphic driving module; the anthropomorphic driving module combines the target motion parameters, driver's driving behavior parameters, and the vehicle's own operating parameters into the enhanced artificial neural network, through the driver's long-term driving process. Carry out training rate and learning, obtain the weights between each neuro...

Embodiment 2

[0094] refer to figure 2 , Figure 4 , the present invention adopts the multi-sensor fusion scheme as:

[0095] The environmental perception module includes machine vision sensors (monocular camera, binocular camera and 3D camera), 77GHz millimeter-wave radar, lidar and car networking V2X.

[0096] The system fuses two or more sensors, and sends relevant parameters such as the speed, relative distance, acceleration, deceleration, and azimuth angle of the dangerous target to the humanoid driving module; the humanoid driving module combines the target motion parameters with the driver's driving Behavioral parameters and the vehicle's own operating parameters are sent to the enhanced artificial neural network, and the driver continuously trains and learns between the layers of the neural network and the neurons during the long-term driving process to obtain To obtain the optimal driving behavior parameters of the driver during the driving process, such as headway distance, bra...

Abstract

The invention discloses an ACC/AEB system based on human-imitating driving. The system comprises an environment sensing module, a data fusion module, a decision control module, a human-imitating driving module and an execution module. By means of the technical scheme, an enhanced neural network is utilized, the learning of driving behavior parameters of a driver can be achieved in the driving process, the driving behavior parameters are compared with the parameters obtained through the calculation of the decision control module and corrected, the situation that in the decision control process,acceleration, deceleration, braking force, acceleration rate and deceleration rate are over high or over low, and accordingly the comfort and the safety of the driving are affected is avoided, so that the ACC/AEB system is more suitable for the driving characteristics of the driver, the drive is made to have the same feeling as his/her own driving, the human-imitating driving in the ACC/AEB process is achieved, and the system better meets the driving requirements of the driver.

Description

technical field [0001] The invention belongs to the technical field of advanced driving assistance. More specifically, the present invention relates to an ACC / AEB system based on anthropomorphic driving. In addition, the invention also relates to a vehicle using the system. Background technique [0002] In recent years, with the gradual popularization of Advanced Driver Assistance Systems (ADAS), the ACC / AEB system has been used as an active safety system as an NCAP scoring item, and countries around the world have mandatory installation of this system to reduce driver fatigue and reduce The occurrence of traffic collision rear-end accident. [0003] However, at present, the ACC / AEB system generally adopts the research on the driver's driving behavior parameters in the development process, and then obtains the driving behavior parameters of a sample driver as the main parameters of the driver's ACC / AEB control. Its existing problems are: [0004] First of all, the sample...
