Embodiment Construction

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0031] Some of the existing in-vehicle temperature sensors are assembled on the panel of the air-conditioning controller, and the in-vehicle temperature sensor can also be tested separately when the air-conditioning controller is tested. Since the temperature sensor in the car will be affected by the ambient temperature during the test process in the production workshop, the test results will be unstable and the production efficiency will be affected.

Abstract

The invention relates to the technical field of automotive electronics and in particular to a device for testing an in-vehicle temperature sensor. The device comprises a plurality of to-be-tested modules for holding a to-be-tested product, and a master control module connected to test modules. The to-be-tested module includes a to-be-tested product fixing module, a communication interface, and a function input / output interface. The master control module includes a data acquisition module, a constant current source module, and DIO modules the number of which corresponds to that of the test modules, a bus communication module, and a signal generation module. An object of the present invention is to provide a device for testing an in-vehicle temperature sensor. The device can provide a constant hardware test condition for testing the in-vehicle temperature sensor, and achieves batch testing before assembly by using an asynchronous parallel test method.

Description

technical field [0001] The invention relates to the technical field of automotive electronics, in particular to a testing device for a temperature sensor inside a vehicle. Background technique [0002] With the rapid development of electronic technology, the technical content of automotive electronic products is increasing day by day, which makes its test content and test items continue to expand. At the same time, customers have increasingly stringent requirements on product quality, ranging from the quality of the vehicle structure to the interior The quality of the modules. Among them, the temperature detection in the car is also a very important module, which is closely related to the air conditioning controller. [0003] Some of the existing in-vehicle temperature sensors are assembled on the panel of the air-conditioning controller, and the in-vehicle temperature sensor can also be tested separately when the air-conditioning controller is tested. Since the temperatur...
