    Abstract: A hybrid vehicle and method of control include an internal combustion engine and at least one traction motor operated in an automatic mode such that the combined wheel torque is a function of accelerator pedal position and vehicle speed. In a select shift mode, wheel torque is also a function of a virtual gear number. The virtual gear number varies in response to driver activation of shift selectors or automatically in response to changes in vehicle speed. The vehicle transitions into select shift mode in response to driver activation of a downshift selector. When the transition occurs, an initial virtual gear number is selected to ensure that wheel torque increases.

    Abstract: A vehicle includes a powertrain having an engine and an electric machine, and a battery configured to power the electric machine. The vehicle further includes a controller programmed to operate the powertrain according to a forecasted torque allocation between the engine and the electric machine. The controller generates forecasted torque allocation for each of a plurality of predetermined route segments based on predicted driver demand. The forecasted torque allocation is confirmed for each of the route segments based on a target battery state of charge corresponding to an endpoint of the route segment while an actual state of charge is within a threshold value of the target battery state of charge.

    Abstract: A hybrid vehicle and method of control include an internal combustion engine and at least one traction motor operated such that engine speed is a function of vehicle speed and target engine power. Target engine power, in turn, is a function of target wheel torque, vehicle speed, and battery state of charge. Target wheel torque, in turn, is a function of vehicle speed and accelerator pedal position. In a select shift mode, these calculations are adjusted based on a virtual gear number which varies in response to driver activation of shift selectors. The adjustments result in decreased engine speed and decreased wheel torque when higher virtual gear number are selected for given accelerator pedal positions and vehicle speeds. The ratio of engine speed to vehicle speed is not necessarily constant when operating in select shift mode.

    Abstract translation: 混合动力车辆和控制方法包括内燃机和至少一个牵引电动机，使得发动机转速是车速和目标发动机功率的函数。 目标发动机功率又是目标车轮转矩，车速和电池充电状态的函数。 目标轮转矩又是车速和加速踏板位置的函数。 在选择换档模式中，这些计算是基于根据换档选择器的驾驶员激活而变化的虚拟齿轮数进行调整的。 当给定的加速器踏板位置和车辆速度选择较高的虚拟齿轮数时，调整会导致发动机转速下降和车轮转矩减小。 当以选择换挡模式运行时，发动机转速与车速的比率不一定是恒定的。
