Abstract: A control apparatus for a vehicle that includes an engine as a drive power source, a rotating machine as an electric power generator, and an electric storage device. The control apparatus executes an automatic drive control for automatically controlling a torque of the drive power source in accordance with a requested drive torque without requiring an acceleration/deceleration operation by a driver of the vehicle. During an engine running of the vehicle, the rotating machine is rotated by the engine to generate an electric power, and a charging amount, by which the electric storage device is to be charged, is controlled by controlling the electric power generated by the rotating machine. The control apparatus is configured, during an automatic driving of the vehicle, to set the charging amount such that the charging amount is smaller when the requested drive torque is small than when the requested drive torque is large.

Abstract: An upper limit charging rate is limited when a speed position of an automatic transmission is high as compared to when the speed position is low, so an engine is hard to enter a high torque state even when the speed position is high. Thus, it is possible to suppress vibrations and noise that tend to occur at the time when the engine is driven at a low rotation speed and high torque. On the other hand, the upper limit charging rate increases when the speed position is low as compared to when the speed position is high, with the result that a charging rate increases, so it is possible to keep a state of charge of a battery within an appropriate range.

Abstract translation: 与速度位置较低相比，当自动变速器的速度位置高时，上限充气率受到限制，因此即使速度位置较高，发动机难以进入高扭矩状态。 因此，可以抑制发动机以低转速和高扭矩驱动时容易发生的振动和噪声。 另一方面，与速度位置较高时相比，当速度位置较低时，上限充电率增加，结果充电率增加，因此可以将电池的充电状态保持在 适当的范围。

Abstract: A controller for a vehicle including a continuously variable transmission mechanism, a mechanical stepped transmission mechanism, and a drive wheel is provided. The controller includes an electronic control unit. The electronic control unit is configured to execute gear change control of the mechanical stepped transmission mechanism so as to establish any simulated gear stage of a plurality of simulated gear stages and to change a gear ratio of the continuously variable transmission mechanism stepwise. When determining that the mechanical stepped transmission mechanism has failed, the electronic control unit is configured to fix the mechanical stepped transmission mechanism at a limp-home mode mechanical gear stage, prohibit a stepped gear change of the continuously variable transmission mechanism, and change the gear ratio of the continuously variable transmission mechanism in a stepless manner on the basis of a vehicle state.

Abstract: A plurality of virtual gear positions are established by an electric continuously variable transmission, and the number of speeds of the virtual gear positions is equal to or larger than the number of speeds of mechanical gear positions of a mechanical stepwise variable transmission. One or two or more virtual gear positions is/are assigned to each mechanical gear position, and shifts among the mechanical gear positions are performed in the same timing as the shift timing of the virtual gear positions. Thus, shifting of the mechanical stepwise variable transmission is accompanied by change of the engine speed Ne, and the driver is less likely to feel uncomfortable even if shift shock occurs during shifting of the mechanical stepwise variable transmission.
