Abstract: A control method controls a series hybrid vehicle in which a drive motor and an internal combustion engine are supported in a vehicle body via a plurality of mount members in an integrated state. The control method using a controller generates electric power using an electric power generation motor, and drives the electric power generation motor using motive power of the internal combustion engine. The control method drives a drive wheel with the drive motor using the generated electric power, and causes the drive motor to generate regenerative torque during deceleration. In the control method, the regenerative torque is generated by the drive motor such that an upper limit of the regenerative torque is restricted to a magnitude at which an engine rotational speed where resonance occurs on the vehicle body floor.

Abstract: A vehicle regenerative braking control device is provided for a vehicle, which comprises wheels and a motor that brakes and drives the wheels. In this way, the vehicle travels by the motor driving the wheels, and brakes by applying a braking force to the wheels with a regenerative braking force of the motor. The vehicle regenerative braking control device comprises a vehicle controller configured to control the motor such that the regenerative braking force is to be decreased at a steady rate during a predetermined time before a state-of-charge of a battery used as a power source of the motor decreases to a level at which the regenerative braking force can no longer be generated as predetermined.

Abstract: An electric vehicle control method for braking of an electric vehicle applies a front braking torque to a front drive motor that drives a front wheel and applies a rear braking torque to a rear drive motor that drives a rear wheel. The method includes: during the braking, executing a torque limiting process (process B, process C, front braking torque control) that reduces the front braking torque and the rear braking torque when a slip of the front wheel is detected; and executing a distribution torque changing process that increases the front braking torque while maintaining a sum of the front braking torque and the rear braking torque when a slip of the rear wheel is detected.

Abstract: When an accelerator pedal operation amount is large enough to generate a driving force after switching from a stopping range to a starting range is performed, in order to prevent a sudden starting immediately after the range switching, an upper limit of the driving force of a driving source is limited to a driving force larger than a holding threshold value for releasing holding of a stopping state of a vehicle and smaller than a required driving force based on the accelerator pedal operation amount.

Abstract: At the time of starting a vehicle, if the vehicle is stopped even without an operation of braking the vehicle, a drive force to be generated before an actual start of the vehicle is limited to or below a predetermined maximum drive force.

Abstract: A vehicle control device controls a vehicle including a drive motor connected to a rotation shaft of wheels, a battery that supplies electricity to the drive motor, and an internal combustion engine connected to the drive motor. The vehicle is equipped with, as traveling modes, a normal mode, and an eco-mode having a larger regenerative braking force than the normal mode obtained such that rotational energy of the wheels is converted into electrical energy. A controller stops the internal combustion engine and switches from the normal mode to the eco-mode when detecting at least an abnormality in the internal combustion engine during traveling of the vehicle.

Abstract: A drive force control part 5 controls a drive force such that a force caused by a change in the drive force to rearwardly tilt a drive source 1 and push a mount member is made smaller than an external force threshold value. In a first region in which the drive force is equal to or above a predetermined lower limit value, the drive force control part 5 limits a change rate per unit time of the drive force to or below a predetermined maximum rate, and in a second region in which the drive force is smaller than the lower limit value, does not limit the change rate per unit time of the drive force to or below the maximum rate.
