The invention discloses a detection method and a detection device for vehicle acceleration weakness and a vehicle. The method comprises the following steps that working condition information of a vehicle and environment information of vehicle running are collected, the working condition information at least comprises the gear of the vehicle, the opening degree of an accelerator pedal, the vehicle speed and the actual acceleration a, and the environment information at least comprises the road slope angle and the altitude; determining a plurality of target accelerations based on the working condition information and the environment information; the multiple target accelerations are corrected, and the expected acceleration a'of the vehicle is obtained; and under the condition that the actual acceleration a and the expected acceleration a'meet preset conditions, it is determined that the vehicle is in an acceleration powerless state. According to the invention, the technical problem of inaccurate and untimely evaluation of vehicle acceleration weakness in the prior art is solved.
本发明公开了一种车辆加速无力的检测方法和检测装置、车辆。其中,该方法包括以下步骤:采集车辆的工况信息和车辆行驶的环境信息,工况信息至少包括车辆的挡位、加速踏板的开度、车速、实际加速度a,环境信息至少包括道路坡角和海拔高度;基于工况信息、环境信息确定多个目标加速度;对多个目标加速度进行修正,获得车辆的期望加速度a′;在实际加速度a和期望加速度a′满足预设条件的情况下,确定车辆处于加速无力状态。本发明解决了相关技术的车辆加速无力评价不准确、不及时的技术问题。
