    摘要： [Object]
    It is to provide a travel controlling device of an electric vehicle capable of preventing, when an accelerator opening decreases, a vehicle speed from rapidly decreasing contrary to a driver's intention, allowing a driver to drive a vehicle without deteriorating an operability.
    [Solution]
    An ECU causes a traction motor to generate a non-one-pedal drive braking torque with which a vehicle speed gradually decreases (step S9), if a change rate of an accelerator opening is smaller than a predetermined rate ("YES" at step S5) when the vehicle speed is higher than a predetermined speed. The ECU includes driving and braking ranges to generate one-pedal and non-one-pedal drive braking torques respectively when the accelerator opening decreases, and causes the traction motor to generate the non-one-pedal drive braking torque if the accelerator opening within the driving range decreases with the vehicle speed higher than the predetermined speed and the change rate of the accelerator opening smaller than the predetermined rate.

    摘要： The invention relates to a method for reliably controlling a braking torque of a drive system (1). In order to be able to reliably control the braking torque, it is proposed that the drive system (1) has a synchronous machine (2) and a changeover apparatus (3), wherein the synchronous machine (2) has phase connections (20), wherein the changeover apparatus (3), in a first state, connects the phase connections (20) to one another in such a way that a first braking torque (M
    Br1 ) is produced at the synchronous machine (2) and, in a second state, connects the phase connections (20) to one another in such a way that a second braking torque (M
    Br2 ) is produced at the synchronous machine (2), wherein the changeover apparatus (3) changes over between the states in such a way that a prespecifiable braking torque (M*) is produced at the synchronous machine (2) on average over time, wherein, in order to produce the first braking torque (M
    Br1 ), the phase connections (20) of the synchronous machine (2) are short-circuited, and wherein, in order to produce the second braking torque (M
    Br2 ), the phase connections (20) of the synchronous machine (2) are connected to at least one resistor (4). The invention further relates to a drive system (1) for carrying out the method, and also to a vehicle, in particular to a rail vehicle, comprising a drive system (1) of this kind.

    摘要： Um ein sicheres Abbremsen einer Transporteinheit eines Langstatorlinearmotors (1) zu ermöglichen, wobei eine Mehrzahl (m) Antriebspulen (Sm) des Langstatorlinearmotors (1) in einem Normalbetrieb derart bestromt wird, dass ein mit einer Transporteinheit (2) gekoppeltes Magnetfeld entlang einer Bewegungsrichtung (x) bewegt wird um die Transporteinheit (2) entlang der Bewegungsrichtung (x) zu bewegen, wird erfindungsgemäß beim Bremsvorgang der Transporteinheit (2) in einen geregelten Kurzschlussmodus (M) geschaltet, in welchem zumindest ein Teil der Antriebspulen (Sm) zumindest über einen ersten Zeitabschnitt in einem Kurzschluss betrieben wird.
