A method for controlling a braking torque of a drive system and for braking a vehicle includes in a first state connecting phase connections of a synchronous machine to one another by a changeover apparatus and short circuiting the phase connections such that a first braking torque develops at the synchronous machine. In a second state the phase connections are connected to one another by the changeover apparatus and to a resistance, such that a second braking torque develops at the synchronous machine. The changeover apparatus periodically switches between the first and second states at a switching frequency of 10 Hz or higher to produce a pre-settable braking torque at the synchronous machine, with the changeover between the first state and the second state being controlled by a timing element in an unregulated manner.

In a vehicle control device provided in a vehicle including a motor configured to apply a regenerative braking force to a wheel, a braking force controlling portion controls torque of the motor such that the motor generates a regenerative braking force corresponding to a requested braking force requested to the vehicle. When the wheel locks during braking, the braking force controlling portion executes an antilock control in which the torque of the motor is controlled such that the lock of the wheel is restrained. An acquisition portion acquires the deceleration speed of the vehicle. A derivation portion derives an expected deceleration speed for the vehicle based on the requested braking force. In a case where the braking force controlling portion executes the antilock control, the braking force controlling portion controls vibration of the motor based on the difference between the expected deceleration speed and the deceleration speed.
