A fire fighting vehicle includes a front axle, a rear axle, an engine, an energy storage device, an electromechanical transmission, a fluid tank configured to store a fluid, a pump configured to provide the fluid from the fluid tank to a fluid outlet, and a power divider positioned between the engine, the pump, and the electromechanical transmission. The power divider includes a first interface coupled to the engine, a second interface coupled to the pump, and a third interface coupled to the electromechanical transmission. The electromechanical transmission is (i) selectively mechanically coupled to the engine by the power divider and (ii) electrically coupled to the energy storage device to facilitate driving at least one of the front axle or the rear axle. The pump is selectively mechanically coupled to the engine by the power divider to facilitate pumping the fluid to the fluid outlet.

A fire fighting vehicle includes a powertrain, an accessory drive, and a controller. The powertrain includes an engine, an energy storage device, and an electromechanical transmission (i) electrically coupled to the energy storage device and (ii) selectively mechanically coupled to the engine. The electromechanical transmission is configured to (a) selectively drive a front axle and/or a rear axle and (b) selectively generate energy for storage in the energy storage device as stored energy. The accessory drive is positioned to receive a mechanical input from the engine and the electromechanical transmission. The controller is configured to selectively operate the powertrain in (i) a standby mode by operating the electromechanical transmission using the stored energy to drive the accessory drive with the engine off and (ii) a rollout mode by operating the electromechanical transmission using the stored energy to drive the front axle and/or the rear axle with the engine off.

A method for controlling a motor vehicle having at least one park lock. A drive train of the motor vehicle has a drive motor, wheel, and a transmission. An operating element actuates the park lock, which can assume a blocking position, in which the park lock blocks the drive train and/or a part of the drive train, and a release position. After actuation of the operating element, the park lock is switched from the release position into the blocking position (or vice versa). Here, the speed of the motor vehicle is determined. After actuation of the operating element and if the park lock assumes the release position beforehand, it is checked whether the speed is greater than a predefined first threshold value. If this check was successful, a first warning signal is produced; and the switching of the park lock into the blocking position is performed.

A method for controlling a parked vehicle includes receiving vehicle identification information from a first terminal, specifying a target vehicle to be controlled based on the vehicle identification information, waking up the target vehicle to be controlled and transitioning the target vehicle to be controlled to a movable state, and transmitting a moving direction to the target vehicle to be controlled.

An electrified fire fighting vehicle includes a chassis, a cab coupled to the chassis, a body coupled to the chassis, a front axle coupled to the chassis, a rear axle coupled to the chassis, a water tank supported by the chassis, an energy storage system coupled to the chassis, a water pump supported by the chassis, and an electromagnetic device electrically coupled to the energy storage system. The electromagnetic device is coupled to the water pump and at least one of the front axle or the rear axle. The electromagnetic device is configured to receive stored energy from the energy storage system and provide a mechanical output to selectively drive the water pump and the at least one of the front axle or the rear axle.

A fire fighting vehicle includes a chassis, a front axle, a rear axle, a powertrain, an accessory drive, and a controller. The powertrain includes an engine, a battery system, and an electromechanical transmission coupled to the battery system, the engine, and at least one of the front axle or the rear axle. The accessory drive is positioned to receive a mechanical input from the engine and the electromechanical transmission. The controller is configured to selectively operate the powertrain in a plurality of operational modes including a standby mode and a hybrid mode. According to the standby mode, the controller is configured to operate the electromechanical transmission using stored energy stored in the battery system to drive the accessory drive with the engine off. According to the hybrid mode, the controller is configured to operate both the engine and the electromechanical transmission.

A system for securing the parking of an automobile vehicle parked on a parking area (Z), the vehicle including two steering wheels, and a actuator to modify the orientation of the steering wheels without the action of the driver, the system including a control unit (UC), a system for detecting a parked state of the automobile vehicle, a sensor for detecting the slope of the parking area, sensor for determining the orientation of the steering wheels with respect to the axis of the vehicle, the control unit (UC) being configured to determine the orientation of the steering wheels to put the vehicle in a decreased danger configuration in case of an unwanted movement of the vehicle, and to sending an instruction to the actuator to orientate the steering wheels according to the orientation determined by the control unit (UC).

A method for operating a motor vehicle. The motor vehicle has an electric traction machine. In a first kind of operation of the motor vehicle, before or during a release of a parking brake of the motor vehicle when the motor vehicle is at a standstill, a desired rotational speed for a rotational speed regulation of the traction machine is set to a value corresponding to the standstill of the motor vehicle, and an actual rotational speed of the traction machine is adjusted to the desired rotational speed.

A method for operating a vehicle that includes: generating, by at least one processor, a start trigger signal based on first driving situation information; in response to the start trigger signal, performing, by the at least one processor, a storage operation that stores in at least one memory (i) driving manipulation data that is generated based on user input from a user of the vehicle, and (ii) navigation data that is generated corresponding to the driving manipulation data; generating, by the at least one processor, an end trigger signal based on second driving situation information; and in response to the end trigger signal, stopping, by the at least one processor, the storage operation that stores the driving manipulation data and the navigation data is disclosed.

Roll-off is considered to be any unwanted vehicle movement after a parking brake is engaged. Roll-off is prevented or reduced by a method and apparatus that adjusts hydraulic brake pressure applied to vehicle wheel brakes if unintended motion is detected when the parking brake is engaged and the vehicle's transmission is not in the park position.
