Vehicle speed control method and device in automatic driving mode, equipment and medium

Abstract

The embodiment of the invention discloses a vehicle speed control method and device in an automatic driving mode, equipment and a medium. The method comprises the steps of acquiring a basic vehicle speed control instruction output by a target vehicle central controller in real time; generating an ideal speed parameter matched with the basic vehicle speed control instruction according to preset processing time delay; according to the difference between the ideal speed parameter and the real-time speed parameter of the target vehicle, generating an additional vehicle speed control instruction tocontrol the vehicle speed of the target vehicle; and returning to execute the operation of generating the ideal speed parameter matched with the basic vehicle speed control instruction according to the preset processing time delay until the real-time speed parameter of the target vehicle tends to be consistent with the ideal speed parameter. According to the technical scheme, the vehicle speed ofan automatic driving vehicle can be accurately and timely controlled, and the production time and the production labor force of the automatic driving vehicle are saved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of signal control, and in particular to a vehicle speed control method, device, equipment and medium in an automatic driving mode. Background technique [0002] As self-driving vehicles are approaching practicality, how to accurately and effectively control the speed of self-driving vehicles has become a common concern. [0003] In the existing automatic driving technology, the vehicle's pedals (acceleration pedal and brake pedal) are controlled by sending control commands through the inherent vehicle speed control system integrated in the vehicle's central controller, so as to achieve the purpose of adjusting the vehicle's running speed . [0004] However, the driving environment, vehicle body weight, changes in vehicle internal sensor settings, wheel wear, and different calibration levels of the pedals will all affect the operating speed of the self-driving vehicle, making it impossi...

Problems solved by technology

[0004]However, driving conditions, vehicle weight, changes in vehicle interior sensor settings, wheel wear, and varying degrees of pedal calibration all affect how quickly an autonomous vehicle can operate, making Simply relying on the control instructions sent by the vehicle central controller cannot achieve the purpose of accurately and timely controlling the running speed of the vehicle, and due to the slight differences in the internal hardware structure of the same type of vehicle during the production process (for example, pedal mechanical installation error), in order to ensure the uniformity of vehicle speed control, the pedals of each vehicle must be calibrated before the vehicle leaves the factory, which consumes a lot of time and labor.
