AI Technical Summary

Problems solved by technology

However, after the automatic driving system is turned on, the driver's reaction time to the environment outside the car changes, and it is impossible to respond to external emergencies in a timely manner.
When an obstacle appears on the road surface and the driver needs to perform emergency braking, compared with when the automatic driving system is not turned on, the driver's reaction time becomes longer, and the vehicle cannot be braked through the brake pedal in time

Abstract

The invention discloses a vehicle braking method, system and equipment and a medium. The vehicle braking method comprises the following steps: receiving a starting signal sent by an automatic drivingsystem; responding to the starting signal, and collecting a speed change rate and a stroke of a brake pedal through a pedal stroke sensor; obtaining an initial brake pressure corresponding to the stroke of the brake pedal based on the fact that the speed change rate is greater than a preset first threshold value; increasing the initial brake pressure to obtain an actual brake pressure; braking thevehicle according to the actual brake pressure. According to the method, the speed change rate of the brake pedal can be detected in real time, and when the speed change rate is larger than the threshold value, the brake pressure is increased, so that rapid braking is achieved; three brake pressure curves are adopted to obtain different initial brake pressures, that is, different brake pressure curves are obtained before and after the automatic driving system is started, so that the actual brake pressure can be changed along with different road conditions and vehicle conditions, and a drivercan brake the vehicle in time.

Description

technical field [0001] The present invention relates to a technology in the field of vehicle control, and more specifically, relates to a vehicle braking method, system, equipment and medium. Background technique [0002] Self-driving vehicles, also known as driverless cars, are intelligent cars that realize driverless driving through computer systems. However, after the automatic driving system is turned on, the driver's reaction time to the environment outside the vehicle changes, and he cannot respond to external emergencies in a timely manner. When an obstacle appears on the road and the driver needs to perform emergency braking, compared with when the automatic driving system is not turned on, the driver's reaction time becomes longer, and the vehicle cannot be braked through the brake pedal in time. Contents of the invention [0003] In view of the problems existing in the prior art, the object of the present invention is to provide a vehicle braking method, system,...
