Abstract: A vehicle control apparatus configured to control a driving motor coupled to at least one wheel includes a motor controller, a vehicle speed calculator, and a vehicle speed setter. The motor controller controls the driving motor in a constant speed driving mode. The vehicle speed calculator calculates a first vehicle speed based on a rotation angle of the driving motor. The vehicle speed setter sets, as a driving speed in the constant speed driving mode, a second vehicle speed based on the first vehicle speed and a brake operation amount. The vehicle speed setter sets zero as the second vehicle speed when the brake operation amount exceeds its threshold and the first vehicle speed falls below its threshold, and sets the first vehicle speed as the second vehicle speed when the brake operation amount does not exceed its threshold r the first vehicle speed does not fall below its.

Abstract: A vehicle control device includes a controller configured to control operation of a driving motor that is to output a driving force for a vehicle. The controller is switchable between a normal mode of controlling acceleration/deceleration based on a driver's acceleration/deceleration operation, and a cruise control mode of maintaining the vehicle speed at a target speed without the acceleration/deceleration operation. The controller is configured to, during the cruise control mode, calculate a torque command value for the motor by using integral control based on an integrated value of a deviation between the vehicle speed and the target speed, and execute an integrated-value adjustment process if the controller determines that the vehicle entered a flat road or an uphill road from a downhill road or a downhill road from a flat road or an uphill road. The process adjusts the integrated value to reduce an absolute value of the integrated value.

Abstract: A driving force controller for vehicle includes a driving force calculator and a driving controller. The driving force calculator calculates an instructed driving force, and includes a first determination unit that determines whether or not a predicted driving force satisfies a first condition. The predicted driving force assumes that the instructed driving force calculated on a first control cycle is changed at a rate of change calculated on the first control cycle, until a second control cycle. The first condition includes that a range between the instructed driving force calculated on the first control cycle and the predicted driving force at least partly cover a first range including a zero driving force. The driving force calculator imposes limitation on the rate of change in the instructed driving force to be calculated in the second control cycle, on the condition that the first condition is satisfied.

Abstract: A vehicle control device includes a controller configured to control operation of a braking device and operation of a driving motor. The controller can switch between a normal mode of controlling acceleration/deceleration in accordance with a driver's acceleration/deceleration operation, and a cruise control mode of maintaining the vehicle speed at a target speed without being dependent on the acceleration/deceleration operation. The controller is configured to execute braking control, including braking by the braking device and regenerative braking by the driving motor, during the cruise control mode in accordance with a change in a vehicle traveling condition.

Abstract: A vehicle control apparatus includes a controller configured to perform creep traveling control in which a vehicle is caused to travel regardless of an accelerator operation. When one or both of front wheels or one or both of rear wheels of the vehicle are determined as having moved onto a step by the controller after the creep traveling control starts, the controller causes a target vehicle speed of the creep traveling control to be lower than a first target vehicle speed until the remaining wheels out of the front wheels and the rear wheels are determined as having moved onto the step. The first target vehicle speed is equal to the target vehicle speed having been set before a time when the one or both of the front wheels or the one or both of the rear wheels are determined as having moved onto the step.

Abstract: A vehicle control device includes a controller switching between normal and constant-speed control modes. The normal mode involves controlling a vehicle driving force in accordance with an acceleration-deceleration operation. The constant-speed control mode involves controlling the driving force regardless of the acceleration-deceleration operation to maintain a vehicle speed at a target vehicle speed.

Abstract: A vehicle control device includes an identifier identifying a vehicle speed of a vehicle having a driving motor, based on a rotation speed of a power transmission shaft, and a controller controlling operation of the driving motor. The controller can switch between a normal mode of controlling acceleration/deceleration in accordance with a driver's acceleration/deceleration operation, and a cruise control mode of maintaining the vehicle speed at a target speed without being dependent on the acceleration/deceleration operation. During the cruise control mode, the controller calculates a torque command value for the driving motor by using proportional control based on a deviation between the vehicle speed and the target speed. If a prediction indicates that torsion in the shaft is to be released, the controller adjusts the torque command value such that an absolute value of torque of a proportional-control component is smaller than when the torsion is not to be released.
