Cruise control test system based on automobile intelligent detection platform and test method thereof

Abstract

The invention discloses a cruise control test system based on an automobile intelligent detection platform, which comprises an HIL hardware platform and a controller system rack. The controller systemrack comprises a controller ECU, and an instrument panel, a steering wheel, an accelerator pedal, a brake pedal, a clutch pedal, a power supply, a brake switch, a clutch switch, a simulation vehiclespeed motor, a direct current motor, a Hall sensor and a position sensor which are connected with the controller ECU, and the controller ECU is connected with the HIL hardware platform. The Hall sensor is fixed above the simulated vehicle speed motor rotating shaft magnet and used for measuring the rotating speed of the simulated vehicle speed motor to replace the actual vehicle speed. The position sensor is used for detecting the position information of the throttle valve and transmitting a signal to the controller ECU; the controller ECU is used for receiving signals of the cruise control switch, the Hall sensor and the position sensor on the steering wheel and outputting control signals to drive the direct-current motor to adjust the opening degree of the throttle valve. The design is not only high in test precision, but also high in test automation degree.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a constant-speed cruise test system and a test method based on an automobile intelligent detection platform, which are mainly suitable for improving test accuracy and test automation. Background technique [0002] With the development of the automobile industry, customers' pursuit of vehicle comfort and safety is getting higher and higher. The development of electronic appliances accounts for an increasing proportion of automobiles, and the corresponding proportion of electrical failure problems is also increasing. , cruise control system has become one of the research directions of intelligent transportation. The performance of the control system of cruise control needs to be tested and verified. The traditional test method uses multimeter, signal generator, oscilloscope, etc. to test, and some functions can be measured A single control system, but it cannot accurately guara...
