    Abstract: A control device for a vehicle includes: an engine (10); an engine torque adjustment mechanism; and a PCM (50) configured to execute vehicle attitude control for, upon satisfaction of a vehicle attitude control executing condition that the vehicle is traveling and a steering angle-related value is increasing, reducing the engine torque to thereby generate deceleration of the vehicle. The PCM (50) is configured, upon satisfaction of a given terminating condition for terminating the vehicle attitude control, to control the engine torque adjustment mechanism to restore the reduced engine torque to an original state before the execution of the vehicle attitude control. The PCM (50) sets a rate of change in the engine output torque being restored, such that it becomes larger as the number of times of combustion per unit time becomes smaller, and restores the engine torque according to the rate of change set in the above manner.

    Abstract: A vehicle system comprises an engine 1, a motor-generator 114 and a controller 60. The engine 1 has a combustion mode in which a part of an air-fuel mixture is combusted by spark ignition, and then the remaining air-fuel mixture is combusted by self-ignition. The controller 60 sets a target additional deceleration based on a steering angle, when a steering wheel 105 is turned, and sets an air-fuel ratio of the air-fuel mixture to either one of a first air-fuel ratio and a second air-fuel ratio which is on a lean side, based on an operating state, when the engine 1 performs the combustion mode. The controller 60 controls an ignition timing so as to generate the target additional deceleration in the first air-fuel ratio, and controls a regenerative electric power generation of the motor-generator 114 so as to generate the target additional deceleration in the second air-fuel ratio.

    Abstract: A control device for a vehicle includes: an engine (10); an engine torque adjustment mechanism for adjusting an output torque of the engine; and a PCM (50) configured, upon satisfaction of a condition that the vehicle is traveling, and that a steering angle-related value pertaining to a steering angle of a steering system is increasing, to control the engine torque adjustment mechanism to reduce the engine torque to thereby generate deceleration of the vehicle so as to control vehicle attitude. The PCM (50) is configured to set a time period from the satisfaction of the condition through until start of reduction in the engine torque, such that it becomes longer, as the number of times of combustion per unit time in the engine becomes larger, and to control the engine torque adjustment mechanism to start to reduce the engine torque when the set time period has elapsed.

    Abstract: Disclosed is a vehicle control device which is applied to a vehicle equipped with an engine (10) and an engine torque adjustment mechanism for adjusting an engine torque. The control device comprises a PCM (50) configured, upon satisfaction of a condition that the vehicle is traveling and a steering angle-related value relevant to a steering angle of a steering device is increasing, to control the engine torque adjustment mechanism to reduce the engine torque, so as to execute a vehicle attitude control for generating vehicle deceleration. The PCM (50) is configured, upon satisfaction of a vehicle attitude control-terminating condition for terminating the vehicle attitude control, to control the engine torque adjustment mechanism to restore the engine torque to an original level of torque before the execution of the vehicle attitude control. The PCM (50) is further configured to gradually ease the vehicle attitude control-terminating condition, as the number of times of combustion per unit time in the engine (10) becomes smaller.
