Problems solved by technology

[0005] In the testing process of the existing technology, usually only one device under test can be tested at the same time, and the test efficiency is low. For example, in the test scenario of at least 3 samples, in order to simulate multiple standby and wake-ups that may occur during the product’s service life , it may take several months, and abnormal conditions cannot be monitored in real time during the test process, which affects test efficiency and test accuracy

Embodiment Construction

[0048] The present invention will be further described below in conjunction with specific embodiments and accompanying drawings, but the protection scope of the present invention should not be limited thereby.

[0049] figure 1 Shows the overall structural block diagram of the sleep wake-up test device of the vehicle-mounted system of the present embodiment, including: a control module 11, which generates corresponding control signals according to preset control instructions; one or more automatic test channels connected to the control module 11 12. Under the control of the control signal, switch the working / standby state of the on-board system 13 under test connected to the automatic test channel 12, and detect the working current and standby current of the on-board system 13 under test. In addition, the sleep-wake test device of this embodiment may further include a power supply module (not shown in the figure) for generating a power supply signal provided to the vehicle sys...

Abstract

The invention provides a sleep wake-up test device of a vehicle-mounted system. The sleep wake-up test device of the vehicle-mounted system comprises a control module and one or more automatic test passages connected with the control module, wherein the control module generates corresponding control signals according to a preset control command, and under the control of the control signals, the automatic test passages are switched to and connected to a work / stand-by state of the vehicle-mounted system to be tested and detect the work current and the stand-by current of the vehicle-mounted system to be tested. The sleep wake-up test device of the vehicle-mounted system can improve the test efficiency of the vehicle-mounted system, shortens the testing time, and improves test accuracy.

Description

technical field [0001] The invention relates to the testing technology of the vehicle system, in particular to a sleep wake-up test device of the vehicle system. Background technique [0002] At present, the application of in-vehicle systems is becoming more and more extensive, and the product functions are becoming more and more complex. With the continuous expansion of the scope of use of automobiles, the corresponding use environments are becoming more and more complex. Therefore, customers' quality requirements for automobiles and in-vehicle systems are also increasing. Higher and higher. [0003] In the prior art, the on-board system is usually connected to the on-board power supply of the car, and is always in the power supply state, but is controlled by the corresponding work / standby control signal (ACC ON / OFF) when the car starts / stops. Due to the complexity of the product and the influence of the environment, when the car starts / stops, the on-board system may not b...
