Several embodiments of the present invention are shown in the accompanying drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein.

[0057] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0058] Embodiment 1

[0059] See also Figure 1 The first embodiment of the present invention provides an ADAS driving evaluation method, the method comprising steps S11 to S15:

[0060] Step S11, when the intelligent driving function of the vehicle is turned on, the vehicle is controlled to perform automatic driving according to the training route corresponding to the parking driving subject, and the first driving data is output accordingly;

[0061] In this embodiment, the vehicle is a smart car equipped with intelligent assisted driving, and the vehicle is equipped with a driving training system, that is, the driving training system is used in the process of driving the vehicle, which can assist the user to improve the vehicle driving level to a certain extent. Among them, the user can be a driver with a short driving experience or a college participating in driving training, which requires the driving training school to introduce the driving training system or use the smart car shown in this embodiment for training and teaching.

[0062] Specifically, when a user drives a vehicle and wants to improve his driving skills through driving training, after the vehicle's intelligent driving function is turned on, the vehicle will first be controlled to drive automatically according to the training route corresponding to the preset parking driving subject, and the corresponding first driving data, that is, the automatic driving data, will be output. It can record data including steering wheel angle, throttle opening, braking force, etc., for use as benchmark data for ADAS driving evaluation.

[0063] The training route for parking driving requires vertical reverse parking, horizontal reverse parking and S-curve driving, which corresponds to driving level training subject 2. It should be noted that the training route can be determined by the user or by scanning the vehicle, and the training route is usually in a closed area, which can have good continuity and can also be composed of multiple sub-routes, such as vertical reverse parking in area A, horizontal reverse parking in area B, and S-curve driving in area C.

[0064] It should be noted that the intelligent driving sensors relied on to control the vehicle to drive automatically according to the training route corresponding to the parking driving subject are conventional visual sensors and radar sensors, and the vehicle is usually completed based on the knowledge points of driver training and / or historical experience, requiring the driving process to be smooth and continuous, so as to have good reference.

[0065] Step S12, obtaining second driving data of the user driving the vehicle manually according to the training route.

[0066] In this embodiment, after the vehicle automatically drives according to the training route and outputs the first driving data, the driving right is returned to the user, and the user is prompted to drive manually according to the above-mentioned training route. After the user drives, the second driving data of the user driving according to the training route is obtained.

[0067] Similarly, the second driving data also records data such as steering wheel angle, throttle opening, and braking force, so that it can be used to compare with the first driving data used as the benchmark data to achieve driving evaluation.

[0068] It should be noted here that the driving order of automatic driving and manual driving can also be swapped, that is, the generation of the first driving data and the second driving data can be swapped, which does not affect the data acquisition in the two driving processes.

[0069] Step S13, comparing the steering wheel angle, throttle opening and braking force corresponding to the first driving data and the second driving data, and outputting steering wheel angle difference data, throttle opening difference data and braking force difference data.

[0070] In this embodiment, the steps of comparing the steering wheel angle, throttle opening, and braking force corresponding to the first driving data and the second driving data, and outputting steering wheel angle difference data, throttle opening difference data, and braking force difference data include:

[0071] The first driving data is screened according to a preset data identifier, and first steering wheel angle data, first throttle opening data, and first braking force data are respectively screened out from the first driving data;

[0072] According to the preset data identifier, the second driving data is screened to respectively screen out the second steering wheel angle data, the second throttle opening data and the second braking force data in the second driving data;

[0073] The first steering wheel angle data is compared with the second steering wheel angle data, the first throttle opening data is compared with the second throttle opening data, and the first braking force data is compared with the second braking force data, and steering wheel angle difference data, throttle opening difference data and braking force difference data are output respectively.

[0074] The steps of respectively comparing the first steering wheel angle data with the second steering wheel angle data, the first throttle opening data with the second throttle opening data, and the first braking force data with the second braking force data, and respectively outputting steering wheel angle difference data, throttle opening difference data, and braking force difference data include:

[0075] Extracting first steering wheel angle values ​​and second steering wheel angle values ​​corresponding to the vehicle being located in a plurality of target areas, respectively, according to the first steering wheel angle data and the second steering wheel angle data;

[0076] Outputting a plurality of steering wheel angle difference values ​​according to the first steering wheel angle value and the second steering wheel angle value corresponding to each target area to obtain steering wheel angle difference data;

[0077] Extracting first throttle opening values ​​and second throttle opening values ​​corresponding to the vehicle being located in a plurality of the target areas respectively according to the first throttle opening data and the second throttle opening data;

[0078] Outputting a plurality of throttle opening difference values ​​according to the first throttle opening value and the second throttle opening value corresponding to each target area to obtain throttle opening difference data;

[0079] Extracting first braking force values ​​and second braking force values ​​corresponding to the vehicle being located in a plurality of target areas, respectively, according to the first braking force data and the second braking force data;

[0080] A plurality of braking force difference values ​​are output according to the first braking force value and the second braking force value corresponding to each target area to obtain braking force difference data.

[0081] Specifically, in this embodiment, after respectively obtaining the first driving data corresponding to the automatic driving and the second driving data corresponding to the manual driving, the first steering wheel angle data, the first throttle opening data and the first braking force data in the first driving data are screened out according to the preset data identifier, and in the same way, the second steering wheel angle data, the second throttle opening data and the second braking force data in the second driving data are screened out.

[0082] Then, based on the first steering wheel angle data and the second steering wheel angle data, the first steering wheel angle value and the second steering wheel angle value corresponding to the vehicle in multiple target areas are extracted respectively, and then multiple steering wheel angle difference values ​​are output according to the first steering wheel angle value and the second steering wheel angle value corresponding to each target area, so as to obtain the final steering wheel angle difference data.

[0083] The target area is any area in the vertical parking area and its adjacent area, the horizontal parking area and its adjacent area, and the curved driving area in the training route. For example, in the vertical parking area and its adjacent area corresponding to reverse parking, the target area is the point often mentioned by the instructor during driving training. By comparing the first steering wheel angle value and the second steering wheel angle value corresponding to the vehicle in multiple target areas, it is equivalent to conducting a steering wheel angle assessment at multiple points, thereby outputting steering wheel angle difference data.

[0084] Similarly, in this embodiment, the first throttle opening data and the second throttle opening data corresponding to the above-mentioned multiple target areas are obtained, the corresponding first throttle opening value and the second throttle opening value are extracted, and the throttle opening difference data is output according to the comparison of the first throttle opening value and the second throttle opening value corresponding to each target area. And in the same way, the braking force difference data is output.

[0085] It should be noted here that the above-mentioned target area is a characteristic area marked when the vehicle travels to a certain position, and is specifically marked during the process of the vehicle performing automatic driving according to the training route corresponding to the parking driving subject.

[0086] For example, during the process of autonomous driving, when a vehicle drives to an area adjacent to a vertical parking area and parks smoothly in the future, the vehicle's steering wheel is turned one circle toward the parking space in advance in the adjacent area, and then the vehicle is reversed into the parking space. The adjacent area is marked as a target area corresponding to the above-mentioned point. Then, when the vehicle is manually driven, when the vehicle drives to the target area, the steering wheel angle of the vehicle in the target area is automatically recorded. After that, the steering wheel angle can be compared, and the throttle opening and braking force can be compared based on the same logic, thereby realizing data comparison.

[0087] Step S14, evaluating the driving condition of the user's manual driving of the vehicle according to the steering wheel angle difference data, the throttle opening difference data and the braking force difference data, obtaining a driving score, and outputting a trajectory comparison video of the first driving data and the second driving data.

[0088] In this embodiment, the step of evaluating the driving condition of the vehicle manually driven by the user according to the steering wheel angle difference data, the throttle opening difference data and the braking force difference data to obtain a driving score, and the step of outputting a trajectory comparison video of the first driving data and the second driving data, the step of obtaining the driving score includes:

[0089] Performing a first average weighted processing on a plurality of steering wheel angle difference values ​​corresponding to a plurality of target areas in the steering wheel angle difference data to obtain a first score;

[0090] Performing a second average weighted processing according to a plurality of throttle opening difference values ​​corresponding to a plurality of target areas in the throttle opening difference data to obtain a second score;

[0091] performing a third weighted average processing on a plurality of braking force difference values ​​corresponding to a plurality of target areas in the braking force difference data to obtain a third score;

[0092] A fourth weighted average process is performed on the first score, the second score, and the third score to obtain a driving score.

[0093] Specifically, a first weighted average is performed based on the multiple steering wheel angle difference values ​​in the steering wheel angle difference data to output a first score, a second weighted average is performed based on the multiple throttle opening difference values ​​in the throttle opening difference data to output a second score, and a third weighted average is performed based on the multiple braking force difference values ​​in the braking force difference data to output a third score, and then the first score, the second score and the third score are fourthly weighted averaged to obtain a final driving score. The driving score is usually a percentage system, for example, the driving score corresponding to this manual driving is 80 points, and the corresponding improvement strategy can be output.

[0094] Step S15, data transmission of the trajectory comparison video, driving score, steering wheel angle difference data, throttle opening difference data and braking force difference data is performed to control a preset terminal device for display.

[0095] In this embodiment, a trajectory comparison video is generated based on the first driving data and the second driving data, and then the trajectory comparison video and the above-mentioned driving score, steering wheel angle difference data, throttle opening difference data and braking force difference data are data transmitted, so that the preset terminal device displays the above information, thereby facilitating the user to understand the driving evaluation of this parking driving.

[0096] Among them, the preset terminal devices include vehicle-mounted terminals, VI instruments, or mobile phones and tablet computers held by users.

[0097] In summary, compared with the prior art, the ADAS driving evaluation method shown in this embodiment has the following beneficial effects:

[0098] When the intelligent driving function of the vehicle is turned on, the vehicle is controlled to perform automatic driving according to the training route corresponding to the parking driving subject, and the first driving data is output accordingly, and the second driving data of the user driving the vehicle according to the training route is obtained, and the steering wheel angle, throttle opening and braking force corresponding to the first driving data and the second driving data are compared, and the steering wheel angle difference data, throttle opening difference data and braking force difference data are output, and the driving condition of the user's manually driven vehicle is evaluated according to the steering wheel angle difference data, throttle opening difference data and braking force difference data to obtain a driving score, and a trajectory comparison video of the first driving data and the second driving data is output, and the trajectory comparison video, driving score, steering wheel angle difference data, throttle opening difference data and braking force difference data are transmitted to control the preset terminal device for display. Then the method shown in this embodiment can be based on the current driving and parking sensors and controllers of the whole vehicle, and a new training mode is added to the software algorithm without increasing the hardware cost, which can quickly improve the driver's proficiency in manual driving and improve the driving level.

[0099] Embodiment 2

[0100] See also Figure 2 The second embodiment of the present invention also provides an ADAS driving evaluation method, the method comprising steps S21 to S25:

[0101] Step S21, when the user manually drives the vehicle according to the training route corresponding to the driving subject, the corresponding driving data is obtained;

[0102] Step S22, extracting the steering wheel angle, throttle opening, braking force and lateral and longitudinal acceleration from the driving data;

[0103] Step S23, comparing the steering wheel angle, throttle opening, braking force and lateral and longitudinal acceleration in the driving data with the steering wheel angle, throttle opening, braking force and lateral and longitudinal acceleration in the pre-collected driving experience data, and outputting steering wheel angle difference data, throttle opening difference data, braking force difference data and lateral and longitudinal acceleration difference data;

[0104] Step S24, evaluating the driving condition of the vehicle manually driven by the user according to the steering wheel angle difference data, the throttle opening difference data, the braking force difference data and the lateral and longitudinal acceleration difference data to obtain a driving score;

[0105] Step S25, transmitting the driving score, steering wheel angle difference data, throttle opening difference data, braking force difference data and lateral and longitudinal acceleration difference data to control a preset terminal device for display.

[0106] The ADAS driving evaluation method shown in this embodiment is basically similar to the ADAS driving evaluation method shown in the first embodiment, except that:

[0107] In this embodiment, there is no need to perform automatic driving of the vehicle. After the driving training system on the vehicle is turned on, manual driving can be performed directly to obtain the corresponding driving data. Then, the steering wheel angle, throttle opening, braking force and lateral and longitudinal acceleration in the driving data are extracted, and compared with the steering wheel angle, throttle opening, braking force and lateral and longitudinal acceleration in the driving experience data obtained in advance, and the steering wheel angle difference data, throttle opening difference data, braking force difference data and lateral and longitudinal acceleration difference data are output. Finally, an evaluation is performed based on the above difference data to obtain a driving score, and the driving score, steering wheel angle difference data, throttle opening difference data, braking force difference data and lateral and longitudinal acceleration difference are data transmitted, so that the preset terminal device displays the above information, thereby facilitating the user to understand the driving evaluation of this driving.
