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

Abstract

A constant speed cruise test system based on an automobile intelligent detection platform, including an HIL hardware platform and a controller system platform, the controller system platform includes a controller ECU and an instrument panel connected thereto, a steering wheel, an accelerator pedal, a brake pedal, Clutch pedal, power supply, brake switch, clutch switch, simulated speed motor, DC motor, Hall sensor, position sensor are connected, the controller ECU is connected to the HIL hardware platform, and the Hall sensor is fixed above the magnet of the simulated speed motor shaft for Measure the rotational speed of the simulated vehicle speed motor instead of the actual vehicle speed; the position sensor is used to detect the throttle position information and transmit the signal to the controller ECU; the controller ECU is used to receive the signals from the cruise control switch on the steering wheel, Hall sensor and position sensor , and output a control signal to drive the DC motor to adjust the throttle opening. This design not only has high test precision, but also has high test automation.

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...
