Abstract: A vehicle control system includes an accelerator sensor which detects an accelerator opening, and a processor which sets a target acceleration of a vehicle based on the detected accelerator opening, sets a target torque of a drive source based on the set target acceleration, and controls the drive source to generate the set target torque. In a case where the target acceleration at a time when the accelerator opening is increased is set as a depression-increasing target acceleration and the target acceleration at a time when the accelerator opening is decreased is set as a pedal-returning target acceleration, under the same condition of the accelerator opening, the processor sets the target acceleration such that the depression-increasing target acceleration and the pedal-returning target acceleration are different from each other in a predetermined range of an upper limit acceleration or less and a lower limit acceleration or greater.

Abstract: To provide a control device for a vehicle capable of controlling the torque of a drive source so as to appropriately balance the suppression of body vibrations and the securing of a transient response during acceleration or deceleration. This control device for a vehicle includes an accelerator position sensor that detects the accelerator opening, a torque adjustment mechanism such as a throttle valve that adjusts the torque of an engine as the drive source of the vehicle, and a powertrain control module (PCM) that controls the torque adjustment mechanism based on the accelerator opening. The PCM sets the target acceleration of the vehicle based on the accelerator opening, sets the target torsion angle of the drive shaft based on the target acceleration, sets the target torque of the engine based on the target torsion, and controls the torque adjustment mechanism based on the target torque.

Abstract: A vehicle control system includes an accelerator sensor which detects an accelerator opening, a target acceleration setting unit which sets a target acceleration of a vehicle based on the detected accelerator opening, a target torque setting unit which sets a target torque of a drive source based on the set target acceleration, and a drive source controller which controls the drive source to generate the set target torque. In a case where the target acceleration at a time when the accelerator opening is increased is set as a depression-increasing target acceleration and the target acceleration at a time when the accelerator opening is decreased is set as a pedal-returning target acceleration, under the same condition of the accelerator opening, the target acceleration setting unit sets the target acceleration such that the pedal-returning target acceleration becomes lower than the depression-increasing target acceleration.

Abstract: A driving force control device for a vehicle is provided, which includes a motor, an engine, and a controller. The controller sets a target torque of the vehicle corresponding to accelerator operation, distributes a target engine torque, based on the target torque, and outputs a control signal corresponding to the target engine torque. The controller estimates a future amount of intake air to a cylinder based on the target engine torque, and estimates an engine torque after a setup time from the present time based on the estimated future amount of intake air. The controller sets a target motor torque after the setup time based on the estimated engine torque after the setup time so that the target torque is achieved, and outputs a control signal corresponding to the target motor torque to synchronize a torque response of the engine with a torque response of the motor.
