摘要： A control device performs braking using a regenerative brake based on power generation in a motor generator in motor-driven traveling and performs a battery protecting process of starting an engine to set up transmission of a driving force between the motor generator and the engine using a clutch and performing braking based on an engine brake when a state of charge of a battery is equal to or greater than a threshold value in the motor-driven traveling. The control device sets a fuel-cutoff-permission rotation speed to a second rotation speed lower than a first rotation speed when the engine is started through the battery protecting process.

摘要： A method for operating a motor vehicle, which includes a drive system, including an electric drive machine, a friction braking system and an actuating element. The actuating element is continuously movable between a first end state and a second end state, a position of the actuating element in the first end state corresponding to a percentage value of 0%, and the position of the actuating element in the second end state corresponding to a percentage value of 100%. An acceleration torque for the motor vehicle is predefined if the positon has a percentage value that is greater than a predefined threshold value, and a deceleration torque for the motor vehicle being predefined if the position has a percentage value that is less than the threshold value. The friction braking system is activated in such a way that the friction braking system generates at least partially the predefined deceleration torque.

摘要： A vehicle includes an engine, a generator, a drive motor, and a filter that collects particulate matter in exhaust gas of the engine. The generator is driven by the engine to generate power. The drive motor is driven with the power generated by the generator. A method for controlling the vehicle includes performing motoring by driving the engine in an operation stop state with the generator, thereby performing fuel cut of the engine and consuming power; prohibiting fuel cut of the engine based on a temperature of the filter; and when a discharge request is made while the fuel cut of the engine is prohibited, performing a power consumption operation in which a negative engine torque is generated in the engine by driving the engine with the generator while performing combustion in the engine.

摘要： A system for controlling a transmission state of a vehicle includes a controller connected to a first drive system and a first transmission including a gear system, a first clutch and a second clutch. The controller is configured to receive a request to change from an initial transmission state to a target transmission state when a propulsion torque is applied to the vehicle. The controller is configured to distribute the propulsion torque such that all of the propulsion torque is applied by a second drive system and the first drive system does not provide any propulsion torque to the vehicle, fully release an off-going clutch from the gear system, control a motor speed based on a rotational speed relation of the target transmission state to reduce a slip speed of the on-going clutch, and fully engage an on-coming clutch to put the first drive system in the target transmission state.

摘要： A method is disclosed for preventing a power reduction in an electric drive system of a vehicle (3) during a journey of the vehicle. The method includes a component-tempering process (P2) in which at least one component (4, 5, 6) of the electric drive system is tempered, such that the method comprises a power reduction prediction process (P1) in which it is checked whether a power reduction is to be expected during a journey. The component-tempering process (P2) is initiated as soon as the power reduction prediction process (P1) has recognized that a power reduction is to be expected during the journey.
