Device and method for controlling automobile throttle

Abstract

The invention relates to a device and method for controlling an automobile throttle. The device and method are applied to control over a throttle of an urban low-speed automobile. The device comprisesa camera, millimeter-wave radar, a vehicle control unit, a throttle pedal, an electronic brake system and a drive motor. Both the camera and the millimeter-wave radar are mounted in the front of theautomobile, the input end of the vehicle control unit is connected with the camera, the millimeter-wave radar and the throttle pedal, and the output end of the vehicle control unit is connected with the electronic brake system and the drive motor. The camera, the millimeter-wave radar and an ultrasonic sensor are combined, judgment on obstacles in front of the automobile is added, the stroke amount of the throttle pedal is judged, serious consequences caused by mistaken treading or violent treading of the throttle can be effectively avoided, and good earlier-stage control is also achieved forautomobile collisions.

Description

technical field [0001] The invention relates to the technical field of automobile control, in particular to an automobile throttle control device and method applied to urban low-speed automobiles. Background technique [0002] In recent years, with the popularization of automobiles, automobiles have begun to come to everyone's side, but it is accompanied by more and more traffic accidents, and more and more people sacrifice their precious lives because of automobiles. A large part of this is caused by the driver's underestimation of the braking distance. Generally, the driver thinks that he will continue to accelerate at a safe distance until he thinks it is time to slow down. This often results in rear-end collisions or other more serious accidents. In addition, in the existing vehicle anti-collision or vehicle control systems, the vehicle not only cannot judge the obstacles around the vehicle, but also cannot distinguish the state of the accelerator pedal being accidentall...

AI Technical Summary

Problems solved by technology

A large part of this is caused by the driver's underestimation of the braking distance. Generally, the driver thinks that he will continue to accelerate at a safe distance until he thinks it is time to slow down, which often results in rear-end collisions or other more serious accidents.

In addition, in the existing vehicle collision avoidance or vehicle control system, the vehicle not only cannot judge the obstacles around the vehicle, but also cannot distinguish the state of the accelerator pedal being accidentally stepped on or overstepped.
