Reliable assessment methods of driver acceptance are needed due to increased interest in high levels of autonomous driving systems. Subjective evaluation methods have mostly been utilized to assess the acceptance of newly developed advanced driver assistance systems because acceptance varies depending on the individual. In this paper, an objective evaluation methodology of driver acceptance for an autonomous driving system was proposed based on objective measurable parameters in the case of automatic lane change situations. To this end, a massive driver–vehicle interaction database was utilized, constructed by a specially designed experimental program. The experiment was carried out with 19 selected drivers (9 experts and 10 novices), supposed as an autonomous driving system. The database consisted of not only various measurable parameters on control commands, vehicle behaviors, and relations with other vehicles but also subjective acceptances. To interpret the driver acceptance, objective parameter sets were derived by two different methods: a statistical significance test and an acceptance sensitivity analysis. Then, a modeling method based on stochastic estimation to evaluate driver acceptance was suggested as an objective evaluation method for the driver acceptance of an automatic lane change system. The data set of the expert drivers was only used for the acceptance evaluation modeling; the other data sets of the novice drivers were used for verifications for the suggested model. The estimation accuracies of the two different models using a significance test and sensitivity analysis were 90.2% and 99.5%, respectively. This objective method for acceptance evaluation can not only be expanded to other functions of an autonomous driving system but also to an entirely autonomous driving vehicle.

“…where 𝜎 is given by𝜎 = 4Δ𝜓 l 2 [26]. To characterise the relationship between the two curvature peak scalars, the parameter c is defined as c = 𝜅 s1 max 𝜅 s2 max (13) where 𝜅 s1 max is the first curvature peak scalar and 𝜅 s2 max is the second curvature peak scalar. Here, c not only represents the relationship between the two curvature peak scalars, but also determines the shape of the planned path.…”

“…And the lane-changing paths should also be personalised [7,8], safety, collision avoidance, and stabilisation [9][10][11]. The acceptance of the driver has also to be considered [12][13][14]. Therefore, it is very important to predict the entire lane-changing path [15].…”

Lane-changing manoeuvres are essential for daily driving tasks. Safety and comfort are the primary issues to be considered during the lane-changing manoeuvres of autonomous vehicles. However, because the traffic environment is complicated and changeable, executing fixed lane-changing manoeuvres cannot guarantee safety and comfort. Thus, it is important to find a flexible method that can plan and re-plan a lane-changing path according to the traffic environment in real time. But that remains smooth to ensure the vehicle occupants stay comfortable. Therefore, this paper proposes a method for planning a flexible and smooth lane-changing path in real time. The proposed method uses the bi-elementary paths to ensure comfort, and clothoid and arc curves are superimposed on the bi-elementary paths to add re-planning flexibility. Additionally, lookup tables and reasonable approximations are employed to quickly generate and evaluate lane-changing paths. The results of the simulations demonstrate that the proposed method is able to plan and re-plan a smooth lane-changing path. Then, the results of vehicle experiments performed based on the embedded controller platform show that the proposed method guarantees real-time performance, that the planned path is easy to follow, and that the planned paths make autonomous vehicle lane-changing manoeuvres safe and comfortable.

With the continuous expansion of the scale of modern power grid and the upgrading of equipment management requirements, monitoring specialty is facing greater challenges. Substation automation system acceptance workload is also gradually expanding. When a large number of signals need to be checked and accepted, the workload of checking signals will naturally increase. When the substation data monitored by the dispatching control center increases, there are too many signals to be checked and accepted. This leads to some problems in the normal monitoring of power grid. The signal in the acceptance is analyzed, and the signal is identified according to the frequency of transmission of the signal and the relevant grid time. Substation automation is based on the user terminal project, and the acceptance requirements will be based on the operation, coordination, scheduling, measurement and maintenance. To cut the passage of the old automation system to the new automation system, care must be taken to prevent data jumps and channel interruptions during the cutting process. The automation system operation technology is constantly developing, and the demand for automation personnel is constantly improving.
