混合动力车辆
摘要：
本发明涉及混合动力车辆。在能够基于本车位置信息而选择性地应用CD模式及CS模式的混合动力车辆中，实现CD模式下的特别的行驶，并减轻伴随于CD模式与CS模式之间的模式切换而给使用者造成的不适感。ECU(26)以如下方式根据模式切换来变更驱动力特性：在CD模式中，与CS模式中相比，相对于同一车速及同一加速器开度的车辆驱动转矩增大。ECU(26)在根据模式切换来变更驱动力特性的情况下，执行车辆驱动转矩随着时间的经过从模式切换前的值向模式切换后的值接近的缓变处理。在该缓变处理中，在基于本车位置信息进行模式切换时，与根据模式开关(28)的操作进行模式切换时相比，使缓变处理中的车辆驱动转矩的变化速度的限制变严。
摘要（英）：

An ECU (26) changes driving force characteristics in accordance with a changeover in mode, such that the vehicle driving torque for the same vehicle speed and the same accelerator opening degree becomes larger during a CD mode than during a CS mode. In changing the driving force characteristics in accordance with the changeover in mode, the ECU (26) executes a slow change process such that the vehicle driving torque approaches a value after the changeover in mode from a value before the changeover in mode as time passes. In this slow change process, the speed of change in the vehicle driving torque in the slow change process is more strictly limited when the changeover in mode is made based on host vehicle position information than when the changeover in mode is made in accordance with the operation of a mode switch (28).
