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 output torque (engine torque) of the engine (10). The vehicle 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 generate vehicle deceleration to control vehicle attitude. The PCM (50) is further configured to gradually ease the condition, as the number of times of combustion per unit time in the engine (10) becomes smaller.

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 vehicle attitude control executing condition that the vehicle is traveling and a steering angle-related value 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 further configured to set a rate of change in the engine output torque being reduced, such that the rate of change becomes larger as the number of times of combustion per unit time in the engine (10) becomes smaller, and to control the engine torque adjustment mechanism to reduce the engine output torque according to the rate of change set by the torque reduction change rate-setting part.

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.

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: A control device for a vehicle includes: an engine (10); an engine torque adjustment mechanism; and a PCM (50) configured, upon satisfaction of a condition that the vehicle is traveling and a steering angle-related value is increasing, to control the engine torque adjustment mechanism to reduce the engine torque to thereby execute a vehicle attitude control for generating deceleration of the vehicle, and, upon satisfaction of a given terminating condition for terminating the vehicle attitude control, to restore the reduced engine output torque to an original state before the execution of the vehicle attitude control. The PCM (50) sets a time period from the satisfaction of the terminating condition through until start of restoration of the engine torque, such that it becomes longer as the number of times of combustion per unit time becomes larger, and starts to restore the engine torque when the set time period has elapsed.
