Abstract

The invention discloses a rapid detection method for a hardware circuit of a vehicle-mounted terminal, and the method comprises an upper computer, a vehicle-mounted terminal and a signal output system. The vehicle-mounted terminal comprises a CAN communication module and a main controller module, and the main controller module comprises a hardware module. The main controller module is used for processing collected information and then sending the information to the data receiving end according to a communication protocol, the upper computer obtains a measured value and an actual value sent bythe main controller module, and the upper computer compares the measured value with the actual value, and judges whether the connection of the hardware module of the main controller is normal or not according to a comparison result. The method has the advantages of quickly detecting the hardware fault of the vehicle-mounted terminal, improving the quality inspection efficiency, reducing the risk of vehicle loading communication errors and the like.

Description

technical field [0001] The invention relates to the field of testing internal components of new energy vehicles, in particular to a rapid detection method for a vehicle-mounted terminal hardware circuit. Background technique [0002] At present, the electric vehicle industry has entered a stage of rapid development, and the number of on-board electronic control components has increased. Previously, the vehicle controller was responsible for the communication of each component through the CAN bus network. Due to the different design schemes of the electronic control components, there are different CAN communication baud rates among the components. A single network architecture is difficult to meet the functional requirements of the vehicle, so the vehicle communication network is divided into several sub-networks. The sub-networks are interconnected through the vehicle bus gateway to form an efficient and convenient network channel, which also reduces the load rate of the C...
