The invention provides a vehicle single pedal driving gradient compensation system. A vehicle includes: a gear selector configured to select between a driving gear and a reverse gear, where the selected gear defines a driving direction; and a controller configured to activate a single pedal driving system in response to a user input and, in response to detecting that the vehicle rolls back beyond a predefined period of time, a feed-forward road grade compensation torque opposite the direction of travel and having a magnitude greater than a feed-forward threshold, the feedback data noise compensation torque in the direction of travel has a magnitude greater than a feedback threshold, and the maximum magnitude of the feed-forward road grade compensation torque is reduced to a predefined value throughout a current key cycle of the vehicle.
本公开提供了“车辆单踏板驾驶坡度补偿系统”。一种车辆,其包括:挡位选择器,所述挡位选择器被配置为在行驶挡和倒车挡之间进行选择,其中所选择的挡位限定行驶方向;和控制器,所述控制器被配置为响应于用户输入,激活单踏板驾驶系统,并且响应于检测到所述车辆回滚超过预定义时间段,前馈道路坡度补偿扭矩与所述行驶方向相反并具有大于前馈阈值的量值,并且在所述行驶方向上的反馈数据噪声补偿扭矩具有大于反馈阈值的量值,在所述车辆的整个当前钥匙循环内将所述前馈道路坡度补偿扭矩的所述最大量值减小到预定义值。
