The vehicle control device is capable of: a front car follow-up travel mode, in which a driving force and a transmission ratio are controlled based on a first accelerator position (AP1) for an inter-vehicle distance to a preceding vehicle to be a target inter-vehicle distance; and an override mode, in which the driving force and the transmission ratio are controlled based on a second accelerator position (AP2) determined by an operation of an accelerator operator performed by a driver. Compared with a second transmission characteristic selected in the override mode, in a first transmission characteristic selected in the front car follow-up travel mode, a threshold of the accelerator position at which at least downshift of a transmission (TM) occurs is set to a higher value or an amount of change of the transmission ratio along with the downshift of the transmission (TM) is set to a lower value.

MODE TRANSITION CONTROL TECHNIQUES FOR AN ELECTRICALLY ALL-WHEEL DRIVE HYBRID VEHICLE
20200031216 · 2020-01-30 ·

Control techniques for an electrically all-wheel drive (eAWD) hybrid vehicle involve determining whether to transition from an electric-only mode to a parallel mode based on a driver torque request or a state of charge (SOC) of a battery system. During the electric-only mode, the electric motor is operated such that a torque reserve is maintained. When the driver torque request exceeds a maximum drive torque that the electric motor is capable of generating, the electric-only to parallel mode transition is performed. This involves the electric motor depleting the torque reserve to provide an expected acceleration feel for the driver while engine and transmission speeds are synchronized. When the SOC of the battery system falls below an SOC threshold, the drive torque of the electric motor is decreased to zero upon engine/transmission speed synchronization such that the battery system can be recharged.

Control apparatus for vehicle

The control apparatus for a vehicle includes a determination unit that determines whether or not a start condition is established, the start condition including when a torque converter is in a lockup state, and when the vehicle is in an accelerating state; and a display control unit that causes an acting number of rotations to be displayed on a tachometer instead of an actual number of rotations when it is determined by the determination unit that the start condition is established. The display control unit calculates the acting number of rotations based on a target value of an input number of rotations of a continuously variable transmission, and varies the acting number of rotations with a rate of change having an absolute value that is greater than an absolute value of a rate of change of the actual number of rotations upon an abrupt change in the target value.

A control method for an electric vehicle controls braking force when the accelerator operation amount is less than a prescribed value and controls drive force when the accelerator operation amount is at least a prescribed value. The electric vehicle control method estimates disturbance torque that acts on the motor as a resistance component relating to gradient; and executes correction whereby the braking force or the drive force is increased/decreased on the basis of the disturbance torque estimated value, such that the resistance component is negated. A determination is made regarding whether or not the accelerator operation amount is a partial equivalent amount and, if at least either the accelerator operation amount on a downhill road is greater than the partial equivalent amount or the accelerator operation amount on an uphill road is less than the partial equivalent amount, the correction amount is reduced.
