Embodiment 1

[0028] Such as figure 1 As shown, a scene test method for a smart car based on ADAS function, including the following steps: select the first lane for the smart car to run, and a lane adjacent to the first lane and in the same direction for the mobile target car to run The second lane, demarcate the only smart car and divide the first lane and the second lane into acceleration section, steady speed section, test section and deceleration section; adopt control device to control the smart car and the moving target The starting time point and driving state of the car, given the trigger signal that the smart car turns to the second lane during the test section, determine whether the smart car collides with the moving target car, if not, record, save and Upload test data and environment variables to the host computer, repeat the test to generate a test curve; if so, intervene in the brakes and restart the test.

Embodiment 2

[0033] Such as Figure 1 to Figure 2 As shown, a scene test method for a smart car based on ADAS function, including the following steps: select the first lane for the smart car to run, and a lane adjacent to the first lane and in the same direction for the mobile target car to run The second lane, demarcate the only smart car and divide the first lane and the second lane into acceleration section, steady speed section, test section and deceleration section; adopt control device to control the smart car and the moving target The starting time point and driving state of the car, given the trigger signal that the smart car turns to the second lane during the test section, determine whether the smart car collides with the moving target car, if not, record, save and Upload test data and environment variables to the host computer, repeat the test to generate a test curve; if so, intervene in the brakes and restart the test. Described smart car keeps course angle 0 ° when described...

Embodiment 3

[0036] The present invention adopts the following props during implementation: a moving target vehicle, a test prop used to replace a real bicycle in a test. The soft target target vehicle is used here, which can avoid damage to the mobile target vehicle in the event of a collision, and can restore the visual and radar characteristics of the real vehicle; the guardrail, the support structure of the guardrail is replaced by plastic material, and the exterior is wrapped with a metal layer to restore the real Visual and radar characteristics of metal barriers; control devices (such as Figure 4 shown).

[0037] In the implementation process of the present invention, the test parameters of the control device are first set, and then the corresponding test section is selected. In the test section, the corresponding acceleration section, steady speed section, test section and deceleration section are matched with different colors for each stage. The cone is used as a distinction to ...

Abstract

The invention provides a scene test method for an intelligent vehicle based on an ADAS function and relates to the field of intelligent vehicle testing. The method comprises steps of: selecting a first lane for driving the intelligent vehicle, and a second lane adjacent to the first lane in the same direction and for driving a mobile target vehicle; calibrating the unique intelligent vehicle and dividing the first lane and the second lane successively into acceleration sections, steady speed sections, test sections and deceleration sections; controlling, by a control device, the start time points and the driving states of the intelligent vehicle and the mobile target vehicle, giving the intelligent vehicle with a trigger signal for turning the intelligent vehicle to the second lane when inthe test section, determining whether the intelligent vehicle collides with the mobile target vehicle; if not, recording, saving and uploading test data and environment variables to a host computer,repeating the test to generate a test curve chart; if so, braking the intelligent vehicle and restarting the test. The scene test method has high scene construction efficiency and high scene restoration degree, can be repeatedly executed and has a good test effect.

Description

technical field [0001] The invention belongs to the field of smart car testing, and in particular relates to a scene testing method for smart cars based on ADAS functions. Background technique [0002] Advanced Driver Assistance System (ADAS), referred to as ADAS, is to use various sensors installed on the car to collect environmental data inside and outside the car in the first time, and carry out identification, detection and monitoring of static and dynamic objects. Tracking and other technical processing, so that the driver can detect possible dangers in the fastest time, so as to attract attention and improve safety. Active safety technology. The sensors used in ADAS mainly include cameras, radars, lasers and ultrasonics, etc., which can detect light, heat, pressure or other variables used to monitor the state of the car. They are usually located in the front and rear bumpers, side mirrors, inside the steering column or windshield of the vehicle. on the glass. Early A...
