Problems solved by technology

However, both the transmission process and the reaction of the braking equipment take time, resulting in a delay between the point in time when the control parameters are determined and the point in time when the braking equipment operates the vehicle
Due to this delay, it is difficult to accurately park the vehicle in the intended location

Abstract

The present application provides systems and methods for determining control parameters associated with a vehicle. The system can execute the method, determining a first reference acceleration at a first time point (610); determining a second reference acceleration at a second time point (620), wherein the first time point and the second time point are determined by a preset The time period is separated; the correction coefficient is obtained (630) by using a simulation model configured to simulate the operation of the vehicle; and determined at a second time point based on the first reference acceleration, the second reference acceleration and the correction coefficient Target Acceleration (640).

Description

technical field [0001] The present application generally relates to systems and methods for unmanned driving technology, and more particularly to systems and methods for controlling braking processes associated with unmanned vehicles. Background technique [0002] With the development of microelectronics and robotics, unmanned driving technology is developing rapidly today. For the control system of an unmanned vehicle, it is important to park the vehicle at a predetermined location precisely, automatically and accurately. Generally, a control system of a vehicle determines a control parameter (eg, acceleration) based on instantaneous driving information (eg, instantaneous speed) of the vehicle, and sends the control parameter to the braking device of the vehicle to control the braking process. However, both the transmission process and the reaction of the braking device require time, resulting in a delay between the point in time at which the control parameters are determi...
