The invention discloses a vehicle target acceleration monitoring method and device. The method comprises the following steps: firstly, acquiring a reference whole vehicle target acceleration of a vehicle and a longitudinal acceleration expected by a driver; wherein the reference whole vehicle target acceleration of the vehicle is an accurate value of the expected longitudinal acceleration. And determining the difference value between the expected longitudinal acceleration and the reference whole vehicle target acceleration as the unexpected longitudinal acceleration of the vehicle. The accelerator pedal opening degree of the vehicle is obtained to obtain the acceleration intention of a driver; and when the unexpected longitudinal acceleration of the vehicle and the opening degree of the accelerator pedal of the vehicle meet preset conditions, it is determined that the obtained target acceleration of the vehicle is abnormal. It can be known that when whether the target acceleration of the vehicle is abnormal or not is considered, the comparison between the target acceleration and the accurate value is considered, the acceleration intention of the driver is determined through the accelerator pedal opening degree of the vehicle, and whether the target acceleration is abnormal or not is comprehensively judged by combining the unexpected longitudinal acceleration and the acceleration intention of the driver; and the monitoring result is more accurate.

    本申请公开了一种车辆目标加速度监控方法及装置,先获取车辆的基准整车目标加速度以及驾驶员期望的纵向加速度。其中,车辆的基准整车目标加速度为期望的纵向加速度的准确值。将期望的纵向加速度和基准整车目标加速度的差值确定为车辆的非期望纵向加速度。获取车辆的油门踏板开度,以获取驾驶员的加速意图。当车辆的非期望纵向加速度和车辆的油门踏板开度满足预设条件时,确定获取的车辆的目标加速度异常。可知,本申请在考虑车辆的目标加速度是否异常时,不仅考虑了其与准确值的比对,还通过车辆的油门踏板开度确定了驾驶员的加速意图,以结合非期望纵向加速度与驾驶员的加速意图,来综合判断目标加速度是否异常,使得监控的结果更加准确。
