A vehicle power supply apparatus includes a first power supply system, a second power supply system, a switch, a switch controller, and an assistance controller. The first power supply system includes a first electrical energy accumulator and an electric device coupled thereto. The second power supply system includes an electric motor coupled to an engine, and a second electrical energy accumulator able to be coupled to the electric motor. The switch controller controls the switch to an electrically conductive state on the condition that a motor assistance control is about to be executed. The assistance controller inhibits the motor assistance control on the condition that a charge state and a discharge state of the first electrical energy accumulator become ungraspable.

Systems and methods provide a drive system control architecture that comprises a seamless interface between original equipment manufacturer (OEM) vehicle systems or components (e.g., accelerator pedal, brake pedal, accessory components, etc.) and third-party (or non-OEM) vehicle systems or components (e.g., motor/generator (MG) and inverter systems, fuel cell and battery systems, transmission, etc.). A universal interface implemented in a vehicle may receive a request for a specified amount of torque from one or more components of a first set of vehicle components, and may determine a balance between one or more components of a second set of vehicle components for delivering the specified amount of torque. The universal interface may then instruct the one or more components of the second set of vehicle components to deliver a commensurate portion of the specified amount of torque.

A control apparatus of a hybrid vehicle which, when a travel mode is switched from an EV mode (second mode) to a series mode (first mode), can warm an exhaust purification catalyst appropriately to suppress deterioration of an exhaust gas, is provided, and configured as follows: If the temperature of the exhaust purification catalyst is equal to or higher than a predetermined temperature, the first mode (series mode) is selected when a required output is equal to or higher than a first determination threshold value; or the second mode (EV mode) is selected when the required output is lower than the first determination threshold value. If the temperature of the exhaust purification catalyst is lower than the predetermined temperature, the first mode is selected when the required output is equal to or higher than the first determination threshold value; the second mode is selected when the required output is equal to or lower than a second determination threshold value; or a specific mode (warm-up mode) is selected when the required output is lower than the first determination threshold value and higher than the second determination threshold value.

Method for operating a driver assistance system in a motor vehicle wherein an action plan comprising at least one measure for the targeted deceleration of the motor vehicle is determined, as well as predictive route data describing the distance to the coasting destination is determined when the driver ends the activation of the gas pedal and at least one potential coasting destination, which requires deceleration of the motor vehicle, is determined, and said measure is used for the longitudinal guidance of the motor vehicle, whereby the measures are selected from the measure group of at least one operation in a free-run operating mode and one operation in a coasting operating mode, whereby a stopping position is determined as the coasting destination and the action plan is determined for the deceleration of the motor vehicle to a complete stop at the stopping position.

Systems and methods for improving operation of a hybrid vehicle are presented. In one example, compensation is provided for a dual mass flywheel positioned in a vehicle driveline. The approaches may reduce driveline torque disturbances.

The present disclosure relates to a method and device for warning a user of a vehicle with an energy storage unit against an energy shortage. According to the present disclosure, an energy quantity is determined that is stored in the energy storage unit at a branching point of a path driven on by the vehicle, and a direction option of the vehicle at the branching point is selected. Further, the one route is determined that is associated with the direction option and starts at the branching point, on which the vehicle is able to reach with the lowest expected energy requirement an energy charging location at which the energy storage unit can be charged. The energy requirement is compared with the energy quantity, and a warning indication is outputted with which the user is warned against the direction option if the energy requirement is greater than the energy quantity.

Method and apparatus are disclosed for lead vehicle monitoring for adaptive cruise control. An example vehicle includes a communication module for V2V communication, a camera, a sensor, and an adaptive cruise control unit. The adaptive cruise control unit is to determine an acceleration oscillation value of a lead vehicle based upon measurements collected via at least one of the camera and the sensor and send, via the communication module, an instruction to the lead vehicle to activate cruise control responsive to determining the acceleration oscillation value exceeds a threshold.

The present invention relates to a method of determining at least one area (ZON) of a road network reachable by a vehicle driving on the road network. The method is based on the use of a dynamic model (MOD) of the vehicle depending on the vehicle speed and acceleration, the construction of a line graph (GA) and a shortest path algorithm (ALG).

A hybrid vehicle having a rear-mounted internal combustion engine, an electric energy accumulator, and at least one electric machine which is provided as a generator for charging the electric energy accumulator during an energy recovery phase and respectively as at least an additional drive to the internal combustion engine during a drive phase, wherein the internal combustion engine drives the rear axle of the hybrid vehicle, and wherein the electric machine, or each electric machine is provided at a distance from the rear axle, in particular in the region of the front axle.

Methods and systems are provided for managing torque arbitration for a hybrid powertrain. In one example, a method may include operating the hybrid powertrain over a predetermined route with a torque arbitration, and updating the torque arbitration based on a vehicle mass.
