The hybrid vehicle includes an engine having a throttle valve and a forced induction device, a second MG (a motor generator), a drive wheel connected to the engine and the second MG, and a controller(an HV-ECU). While the forced induction device performs boosting, the controller performs a reduction rate restricting process for restricting a target engine torque reduction rate in magnitude to beless than an upper limit rate to prevent a throttle opening degree from rapidly decreasing. Further, the controller performs MG regenerative control for controlling the second MG so that regenerativebraking by the second MG compensates for engine brake reduced by the reduction rate restricting process.
本发明涉及混合动力车辆和控制混合动力车辆的方法。混合动力车辆包括:发动机,该发动机具有节气门和增压进气装置;第二MG(电动发电机);驱动轮,所述驱动轮被连接至发动机和第二MG;以及控制器(HV‑ECU)。在增压进气装置进行增压时,控制器执行减小速率限制处理,用于将目标发动机扭矩减小速率的大小限制为小于上限速率,以防止节气门开度迅速减小。此外,控制器执行MG再生控制,用于控制第二MG,使得通过第二MG的再生制动补偿由减小速率限制处理减小的发动机制动。
