Abstract: In a hybrid vehicle, an ECU executes a forced charging control for forcibly charging a battery by using an engine and a vehicle driving device in a case where a remaining capacity of the battery is equal to or less than a predetermined value. In a case where an evaluation value shows a degree of deterioration of the battery attributable to excessive charging, the ECU uses a first electric power as an electric charging power for charging the battery when an absolute value of the evaluation value is equal to or lower than a first threshold, and uses a second electric power falling short of the first electric power as the electric charging power for charging the battery when the absolute value of the evaluation value is higher than the first threshold in a case where the forced charging control is executed while the hybrid vehicle is stopped.

Abstract: In a hybrid vehicle, each of an engine and an MG1 is mechanically coupled to a drive wheel with a planetary gear being interposed. The planetary gear and an MG2 are configured such that motive power output from the planetary gear and motive power output from the MG2 are transmitted to the drive wheel as being combined. A controller makes WGV diagnosis for diagnosing whether or not a waste gate valve is normally controllable by issuing an instruction to a WGV actuator while the controller stops combustion in the engine and controls the MG1 and the MG2 in coordination to perform motoring of the engine during traveling of the hybrid vehicle.

Abstract: The hybrid vehicle includes an engine, a motor connected to the engine, and an electronic control unit configured to control the motor to execute motoring to rotate a crankshaft of the engine. The electronic control unit is configured to execute speed-drop offset control when a rotation speed of the engine falls below a first rotation speed that is lower than a self-sustaining rotation speed of the engine while the engine is operated in a self-sustaining manner at the self-sustaining rotation speed.

Abstract: A control system for vehicles that controls drive force and acceleration smoothly without causing a shock, in response to an operation of an accelerator pedal. A hysteresis is set between an input value and an output value of angle of the accelerator pedal. The hysteresis includes a deadband and an asymptotic range. The output value is not changed significantly with respect to a change in the input value if an angle of the accelerator pedal is changed within the deadband, and the output value is changed continuously with respect to a change in the input value based on a predetermined function if an angle of the accelerator pedal is changed within the asymptotic range.

Abstract: A hybrid vehicle includes: an internal combustion engine; a rotating electric machine; a planetary gear mechanism to which the internal combustion engine, the rotating electric machine and an output shaft are connected; a catalyst that purifies exhaust gas of the internal combustion engine; and a controller that controls the internal combustion engine and the rotating electric machine. The controller controls the internal combustion engine and the rotating electric machine to perform catalyst temperature control to shift an operating point on a map representing a relationship between rotation speed of the internal combustion engine and torque generated by the internal combustion engine so that the catalyst has a temperature within an appropriate temperature range. Degradation of the catalyst can be suppressed without deteriorating the function of the catalyst.

Abstract: An HV-ECU performs processing including calculating requested system power, calculating requested engine power when an engine activation request has been issued, setting an operating point on a predetermined operating line, setting an upper limit value of magnitude of an amount of lowering in engine rotation speed to a first value when a vehicle is in a sport running state and when the previous operating point is within a forced induction range, setting the upper limit value to a second value when the vehicle is not in the sport running state or when the previous operating point is not within the forced induction range, correcting the operating point, and outputting an engine operation state command, a first MG torque command, and a second MG torque command.

Abstract: In a hybrid vehicle, each of an engine and an MG1 is mechanically coupled to a drive wheel with a planetary gear being interposed. The planetary gear and an MG2 are configured such that motive power output from the planetary gear and motive power output from the MG2 are transmitted to the drive wheel as being combined. When a first condition is satisfied during traveling of the vehicle, a controller stops combustion in the engine and performs motoring by the MG1 such that the planetary gear outputs deceleration torque. When a second condition in addition to the first condition is satisfied (YES in S20) during deceleration of the hybrid vehicle with deceleration torque, the controller performs motoring with throttle opening being set to first opening or larger and WGV opening being set to second opening or smaller.

Abstract: An HV-ECU calculates requested output torque Tec based on requested power and compares the requested output torque with controlled upper limit torque Teth. When requested output torque Tec has attained to controlled upper limit torque Teth, the HV-ECU restricts output torque of engine to controlled upper limit torque Teth and calculates actual output torque Ter at that time. Then, the HV-ECU calculates a difference (differential torque ΔTe) between controlled upper limit torque Teth and actual output torque Ter. The HV-ECU learns controlled upper limit torque Teth based on differential torque ΔTe.

Abstract: When a catalyst temperature is lower than a predetermined temperature on a second or subsequent start of an engine since system activation of a vehicle, a catalyst warm-up request is output for the purpose of warming up a catalyst in a catalytic converter. An output limit Wout of a battery is not increased in response to a second or subsequent output of the catalyst warm-up request, while being increased in response to a first output of the catalyst warm-up request. Accordingly, the catalyst warm-up in response to the second or subsequent output of the catalyst warm-up request since the system activation suppresses excessive output of electric power from the battery and thereby suppresses deterioration of the battery. Catalyst warm-up is performed in response to the second or subsequent output of the catalyst warm-up request. This suppresses deterioration of emission. As a result, this configuration satisfies both (balances) suppression of deterioration of the battery and suppression of deterioration of emission.

Abstract: A controller for a hybrid electric vehicle including an internal combustion engine is provided. The internal combustion engine includes a filter arranged in an exhaust passage collect particulate matter from exhaust gas. The controller executes a first deceleration control process, a second deceleration control process, and a selection process. The first deceleration control process uses a fuel cutoff process when deceleration of the hybrid electric vehicle is required. The second deceleration control process does not use the fuel cutoff process when deceleration of the hybrid electric vehicle is required. The selection process selects execution of the second deceleration control process when a PM deposition amount is greater than or equal to a threshold value and selects execution of the first deceleration control process when the PM deposition amount is less than the threshold value.
