摘要： A controller is configured to control a vehicle that includes an internal combustion engine and an automatic transmission. The controller is configured to execute a shifting process that switches a gear ratio of the automatic transmission and a lean operation process that operates the internal combustion engine with an air-fuel ratio of the air-fuel mixture in a cylinder leaner than a stoichiometric air-fuel ratio. The controller is further configured to, when executing the shifting process during execution of the lean operation process, set an air-fuel ratio in a case in which the shifting process is being executed to a value closer to the stoichiometric air-fuel ratio than an air-fuel ratio in a case in which the shifting process is not being executed.

摘要： A damping control device for a hybrid vehicle is provided that make it possible to suppress behavior that differs from a request of a driver. The damping control device includes a controller that calculates an amount of change in a target driving torque, and calculates an amount of change in a target motor torque. The damping control device also includes a damping rate variation unit that sets the damping of a feed forward control unit to a first damping rate when the target driving torque change amount and the target motor torque change amount both are positive or negative, and to a second damping rate, which is smaller than the first damping rate, when the target driving torque change amount and the target motor torque change amount have opposite positivity or negativity.

摘要： Misfire detection techniques for a hybrid electric vehicle (HEV) including an internal combustion engine and an electric motor involve utilizing a crankshaft speed sensor configured to generate a crankshaft speed signal indicative of a rotational speed of a crankshaft of the engine that is coupled to the electric motor via a flywheel. The techniques also utilize a controller configured to control the electric motor to provide a vibrational response to dampen disturbances to the crankshaft, receive the crankshaft speed signal, selectively modify the crankshaft speed signal to obtain a modified crankshaft speed signal, and detect a misfire of the engine based on the modified crankshaft speed signal and a set of thresholds including at least one of a negative misfire threshold and a positive vibrational response threshold.

The method includes comparing a battery state of charge (SOC) with a predetermined SOC when a regenerative braking of the electric vehicle is required and calculating a size of vibration component of the electric vehicle when the battery SOC is less than the predetermined SOC. Further, the size of vibration component is compared with a first predetermined value and a vibration reduction torque of a driving direction is limited when the size of vibration component is less than the first predetermined value.
