Autopilot

Abstract

The present invention provides an automobile automatic driving device, comprising a shift manipulator, a shift manipulator control module, an accelerator pedal mechanical leg, a brake pedal mechanical leg, a clutch pedal mechanical leg, a mechanical leg control module, a vehicle speed detection module, and an engine speed detection module and on-board computer control system. The invention can adapt to various car models, has simple structure, small volume, does not occupy the normal driving space of the driver, reduces the risk of auto-driving and automobile experiments, and reduces the transportation cost of automobile experiment transitions; the driving of mechanical legs and shifting manipulators The motors all use high-precision servo motors and high-precision motor state sensors, and communicate with the on-board computer control system in real time, which improves the control accuracy and stability; the space parallel four-bar linkage constitutes the shift device of the shift manipulator, which has multiple space The degree of freedom enables efficient shifting operations on the gearbox.

Description

technical field [0001] The invention relates to the technical field of automobile automatic driving devices and test vehicles, in particular to a mechanical device for coordinatingly controlling automobile clutch pedals, brake pedals, accelerator pedals and gearbox shifting devices, which can replace human drivers to complete automobile automatic driving work . Background technique [0002] The automatic driving device of the car can automatically control the clutch pedal, brake pedal, accelerator pedal and gearbox shifting mechanism of the car without modifying the structure of the car when the car is driving automatically or for testing. In the research of unmanned vehicles, the automatic driving device of the vehicle must be able to complete the command action issued by the control system of the unmanned vehicle, and control the vehicle to drive automatically; it must be able to adapt to different vehicle platforms and complete the automatic driving operation of different...

AI Technical Summary

Problems solved by technology

Since the tensile deformation of the steel wire rope is relatively large, and slippage may occur at the same time, it is difficult to improve the transmission accuracy

It is difficult to control the speed and position accuracy of the mechanical legs, which affects the stability and accuracy of automatic driving

The structure of the driving actuator is relatively complex and bulky, and it needs to be arranged on the driver's seat. During the transition test, it must be transported and hoisted by a wrecker trailer, which is very inconvenient and increases the test cost.
