Problems solved by technology

The PID controller is based on the feedback control method that takes the difference between the acceleration target value and the current acceleration value as an input, and there is a certain hysteresis; and the PID controller is mainly based on a linear proportional link, and the same set of parameters is difficult to adapt to different working conditions. Therefore, a large amount of parameter calibration and matching work is required.

Abstract

The invention discloses a vehicle driving control method and device, and equipment, and relates to the field of vehicle control, and the method comprises the steps: obtaining the current first driving state data of a vehicle and the second driving state data of a target vehicle; determining a current vehicle distance between the vehicle and the target vehicle and a target vehicle distance between the vehicle and the target vehicle; based on a preset acceleration planning model, determining an acceleration control strategy of the vehicle according to the first driving state data, the second driving state data, the current vehicle distance and the target vehicle distance, and determining the acceleration planning model based on a piecewise function; and controlling the driving state of the vehicle according to the acceleration control strategy. Acceleration planning results under different working conditions can be simply and quickly calculated, the calculation amount is small, the occupied calculation resources are few, implementation is easy, meanwhile, the acceleration planning results accord with human driving habits, and the comfort level of drivers and passengers can be effectively improved.

Description

technical field [0001] The present application relates to the field of vehicle control, in particular to a vehicle driving control method, device and equipment. Background technique [0002] In the intelligent driving system configured on the vehicle, for example: AEB (Autonomous Emergency Braking, autonomous emergency braking function) or ACC (Adaptive Cruise Control, adaptive cruise function) need to accurately control the acceleration of the vehicle to achieve precise control of the braking distance or The target of the following distance. [0003] In related technologies, a PID (proportional-integral-derivative) controller is used to plan and adjust the acceleration of the vehicle. The PID controller is based on the feedback control method that takes the difference between the acceleration target value and the current acceleration value as an input, and there is a certain hysteresis; and the PID controller is mainly based on a linear proportional link, and the same set ...
