Embodiment 1

[0051] figure 1 It is a schematic flowchart of a testing method for a vehicle collision warning system according to an embodiment of the present invention.

[0052] Such as figure 1As shown, the test method for vehicle collision warning system includes the following steps:

[0053] Step S100, obtain the estimated collision time between the tested vehicle and the target obstacle in the collision test; the target obstacle here can be regarded as a vehicle, and the estimated collision time is based on the distance between the tested vehicle and the target obstacle, the The speed of the test vehicle and the speed between the target obstacles are calculated.

[0054] Step S200, comparing the estimated collision time with the preset collision time, and sending an alarm signal when the estimated collision time is less than the preset collision time;

[0055] Step S300, converting the alarm signal into a voltage signal;

[0056] Step S400, select a preset table from a plurality of...

Embodiment 2

[0081] The difference between embodiment 2 and embodiment 1 only lies in:

[0082] image 3 It is a schematic flowchart of a testing method for a vehicle collision warning system according to another embodiment of the present invention. Such as image 3 As shown, before step S400, it also includes:

[0083] Step S310, arranging the plurality of preset tables in the order of increasing or decreasing in size of the braking time points in the preset tables. Step S310 and steps S100 , S200 , and S300 are in no particular order.

[0084] After step S310, also include:

[0085] Step S400', select a preset table in the middle of multiple preset tables, brake the vehicle according to the corresponding braking conditions in the preset table, and judge the distance between the tested vehicle and the target obstacle after braking Whether it is within the preset distance range;

[0086] Step S420', if the distance is within the preset distance range, the corresponding braking condit...

Embodiment 3

[0089] The difference between embodiment 3 and embodiment 1 only lies in:

[0090] Before step S400, it also includes:

[0091] Step S310, arranging the plurality of preset tables in the order of increasing or decreasing in size of the braking time points in the preset tables.

[0092] After step S310, the following steps are also included:

[0093] Select the preset tables in sequence from the first preset table, and brake the vehicle according to the corresponding braking conditions in the preset table until the vehicle is braked according to the corresponding braking conditions in the Nth table. The distance between the tested vehicle and the target obstacle is within the preset distance range, and the vehicle is braked according to the corresponding braking conditions in the N-1th table, and the distance between the tested vehicle and the target obstacle is satisfied. The test is stopped when the distance is within the preset distance range, so as to determine all target...

Abstract

The invention provides a test method and a test system for a vehicle collision warning system, and relates to the field of vehicle intelligent driving. The present invention converts the alarm signal sent by the vehicle system into a voltage signal during the collision test of the vehicle, and controls the vehicle to brake according to the voltage signal, thereby avoiding being affected by the reaction time of the tester during the test and improving the The accuracy of the test results is improved, while the test time is saved and the test efficiency is improved.

Description

technical field [0001] The invention relates to the field of vehicle intelligent driving, in particular to a test method and a test system for a vehicle collision warning system. Background technique [0002] The Forward Collision Warning System (FCW) is one of the functions of the Advanced Driver Assistance System (ADAS). It can monitor the vehicle in front at all times through radar and other systems, and judge the distance, orientation and relative speed between the vehicle and the vehicle in front. When there is a potential collision Warning to the driver in case of danger, reminding the driver to take measures such as braking to avoid collision. During the development of the system, a lot of experimental verifications need to be done to solve the related problems of software, hardware and system. [0003] At present, when conducting the front collision warning system (FCW) test, the target vehicle equipped with communication equipment drives in front of the test vehicl...
