Problems solved by technology

The on-board navigation module includes hardware equipment and corresponding navigation software. In the routine navigation test process, in order to obtain actual GPS signals, tests such as traffic light reminders, route error correction, speeding reminders, and route re-planning are performed to confirm the navigation module. Safety, stability, reliability, etc., generally need to be tested on the road by actual driving, and then observe whether the navigation software gives various reminders according to the road test. This method often requires real vehicle resources, and requires the driver to drive the vehicle. Drive test, time-consuming and expensive, and high cost

Embodiment Construction

[0020] The specific implementation manner of the present invention will be described in further detail below by describing the best embodiment with reference to the accompanying drawings.

[0021] This application sends the coordinates of a desired route to the navigation software at a certain speed to observe and test whether the navigation software can broadcast correspondingly, so as to test the navigation equipment. For navigation software, it is equivalent to driving on the actual road. Realized that it is possible to simulate driving anywhere in the office, saving money and improving the navigation test cycle. The specific plan is as follows:

[0022] A vehicle navigation module simulation drive test system includes a signal generating device for simulating and generating GPS signals. The signal generating device sends simulated GPS signals and is received by a GPS antenna of a navigation device. Different analog GPS signals can make the navigation software produce dif...

Abstract

The invention discloses a vehicle-mounted navigation module simulation drive test system, which comprises a signal generation device for simulating and generating a GPS signal, and is characterized inthat the signal generation device sends the simulated GPS signal and the simulated GPS signal is received by a GPS antenna of navigation equipment. The system and method have the advantages that theGPS signal is generated in an analog simulation mode and received by the navigation equipment, so that the navigation software equipment can be tested without road test, the method is simple and convenient, the cost is low, the efficiency is high, the start time is saved, and the navigation development period is shortened.

Description

technical field [0001] The invention relates to the field of vehicle testing, in particular to a vehicle navigation module simulation road testing system and method. Background technique [0002] As the necessary equipment of the vehicle, the vehicle navigation module can navigate by obtaining GPS signals to assist driving. The on-board navigation module includes hardware equipment and corresponding navigation software. In the routine navigation test process, in order to obtain actual GPS signals, tests such as traffic light reminders, route error correction, speeding reminders, and route re-planning are performed to confirm the navigation module. Safety, stability, reliability, etc., generally need to be tested on the road by actual driving, and then observe whether the navigation software gives various reminders according to the road test. This method often requires real vehicle resources, and requires the driver to drive the vehicle. Drive testing is time-consuming, expe...
