Gas electric hybrid type driving robot for automobile test

Abstract

The mixed pneumatic and electric driving robot is used in replacing test person in automobile experiment. It has shifting manipulator control box set on the driver's seat in the test automobile, mechanical throttle leg connected to the throttle pedal, mechanical braking leg connected to the brake pedal, mechanical clutch leg connected to the clutch pedal, shifting manipulator connected to the automobile shifting lever, steering wheel fixer used in locking the steering wheel, and angle sensors on the mechanical legs and manipulator to obtain their positions. The driving robot has high automobile speed tracing precision, high repeatability, reliable contrast test datan and other advantages, and may be used in replacing person to complete various automobile experiments.

Description

technical field [0001] The invention relates to a gas-electric hybrid driving robot device capable of replacing human test personnel for automobile tests on a chassis dynamometer, and belongs to the technical field of automatic driving devices for automobile tests. Background technique [0002] The driving robot for automobile test is a device that replaces the test personnel in the automobile test on the chassis dynamometer. The performance of the car needs to improve the design with the help of a large number of tests, the car performance test, reliability test and environmental test carried out on the indoor chassis dynamometer (or called the drum test bench), the exhaust gas emitted by the car, the equipment emitted Noise, changes in ambient temperature, and long-term boring driving will cause some damage to the driver, so it is more suitable for robots to operate. In addition, the rapid increase in the number of automobiles has made the poll...

AI Technical Summary

Problems solved by technology

The disadvantage of the hydraulic drive method is that it requires high oil tightness and complicated mechanism; although the air source is easy to obtain and the mechanism is simple in the pneumatic drive method, due to the high positioning accuracy of the throttle mechanical leg, if all the pneumatic drive methods are used, the actuator And the detection and control system is complex;

[0004] The electric method is generally driven by a DC or AC servo motor, which requires additional transmission mechanisms such as a reducer and a worm gear, which is costly. In addition, the design of the actuator is very complicated to realize the fast separation and fast and slow engagement of the clutch.

At present, there is no self-driving robot device for automobile testing in China, and foreign technologies are kept as company secrets and are not disclosed to the public.
