Provided is an acceleration control system for an electric vehicle. A vehicle includes an electric machine, a battery, an accelerator pedal, a battery cooling system, and a controller. The electric machine is configured to propel the vehicle. The battery is configured to provide electrical power to the electric machine. The battery cooling system is configured to cool the battery in a plurality of cooling modes. A transition between cooling modes of the battery cooling system corresponds to either an increase or a decrease in battery power being utilized to cool the battery. The controller is programmed to truncate an acceleration request under certain conditions to prevent an increase in battery power output in order to reduce a rate at which the battery temperature increases and to prevent a transition to a cooling mode that requires an increase in battery power output.

    本公开提供“用于电动车辆的加速度控制系统”。一种车辆包括电机、电池、加速踏板、电池冷却系统和控制器。所述电机被配置为推进所述车辆。所述电池被配置为向所述电机提供电力。所述电池冷却系统被配置为以多种冷却模式冷却所述电池。所述电池冷却系统的冷却模式之间的转换对应于用于冷却所述电池的电池功率的增加或减小。所述控制器被编程为在某些条件下截断加速度请求以防止电池功率输出的增加,以便降低所述电池温度增加的速率并防止转换到需要增加电池功率输出的冷却模式。
