Embodiment Construction

[0025] The specific implementation manners of the present invention will be further described below with reference to the accompanying drawings.

[0026] A distributed drive electric passenger car adaptive cruise control method, the control method includes the following specific steps:

[0027] Step 1: Lock and follow the target vehicle. When the vehicle is driving normally without failure, start the adaptive cruise function, and lock the vehicle in front of the lane as the following target vehicle;

[0028] Step 2: Perception of target movement and attitude. The vehicle fusion sensor module receives camera video and millimeter wave radar information for data fusion, integrates target screening algorithm, and completes the detection of the state of the vehicle in front and lane line information;

[0029] Step 3: Curve area detection: After the vehicle in front starts to enter the curve, the vehicle fusion sensor module detects the deviation angle θ information, and the vehicle...

Abstract

The invention discloses a control method for adaptive cruising curves of a distributed drive electric passenger car. The control method includes the following specific steps: locking and following the target vehicle -> perception of the target's motion posture -> detection of the curve area -> determination of the curvature of the curve Estimation -> Estimation of yaw rate -> Judgment of vehicle control rights -> Adaptive cruise control of vehicle curves. The present invention has obvious advances and innovations in terms of target recognition accuracy and curve driving safety, and proposes a new control method for the loss and locking of cruise targets and vehicle body sideslip control during curves. It effectively solves the deficiencies and defects of the previous adaptive cruise system and improves driving safety.

Description

technical field [0001] The invention relates to the technical field of self-adaptive control of new energy buses, and more specifically relates to a control method for adaptive cruising curves of distributed drive electric buses. Background technique [0002] Adaptive cruise control (ACC), as a research hotspot in automotive active safety and intelligent transportation systems, can effectively reduce the driver's operating burden during driving, increase road traffic flow, and improve vehicle driving comfort. However, the current adaptive cruise system for electric buses has deficiencies and defects in the design, especially in curved road conditions, it will lose the target to follow after entering the curve, and may misjudge the vehicle in the adjacent lane as the vehicle in this lane. target, or make a misjudgment of the curvature of the curve without decelerating in advance, or directly exit the adaptive cruise function when the curve is turned, which will bring safety h...
