The application discloses a vehicle load testing device, which includes a connection interface unit, a power supply input unit, a power supply output unit and a signal test unit; the connection interface unit is connected to the power supply output unit and the signal test unit, and the power supply input unit, the power supply output unit and the signal test unit The test units are connected in sequence; the connection interface unit is connected to the vehicle load controller, and the first preset number of amplifying interfaces is selected according to its connection line to amplify; the power supply input unit is connected to the external power supply to obtain external power supply; the power supply output unit is converted to the vehicle Power supply; the signal test unit is connected to at least one amplifying interface, and tests the control signal corresponding to the output of at least one amplifying interface according to the intelligent driving function requirements. The device has multiple amplifying interfaces, which can be connected to the vehicle load controller to amplify its multi-channel connection lines to meet the test work of complex signals of multi-channel connection lines, speed up the research and development progress, and shorten the development cycle.
Description
technical field [0001] The present application relates to the technical field of vehicle testing, and in particular, to a vehicle load testing device. Background technique [0002] With the rapid development of science and technology, vehicle intelligent driving technology is becoming more and more mature, and the realization of vehicle intelligent driving does not only rely on the general purpose input / output (English: General Purpose Input Output, GPIO), controller area network required by traditional vehicle functions. Bus (English: Controller Area Network, referred to as: CAN) and automotive serial communication network (English: Local Interconnect Network, referred to: LIN) and other communication protocol lines, but also highly integrated video sensors, radar, inertial navigation and global positioning system GPS (Global Positioning System) and a large number of sensors and signal processors are collectively referred to as vehicle loads. [0003] In order to realize h...
