A vehicle controlling apparatus includes an engine processor, an electric motor, an electric power storage, an SOC detector, an internal resistance detector, and a resistance threshold setting unit. The engine processor is configured to stop an engine of a vehicle on the basis of a stop condition, and start the engine on the basis of a start condition. The engine processor is configured to prohibit a stop of the engine based on the stop condition based on determining that an internal resistance of the electric power storage detected by the internal resistance detector is equal to or greater than a resistance threshold set by the resistance threshold setting unit on the basis of a state of charge of the electric power storage, and permit the stop of the engine based on determining that the internal resistance is less than the resistance threshold.

Vehicles may be composed of a relatively few number of “modules” that are assembled together during a final assembly process. An example vehicle may include a body module, a first drive module coupled to a first end of the body module, and a second drive module coupled to a second end of the body module. One or both of the drive modules may include a pair of wheels, a battery, an electric drive motor, and/or a heating ventilation and air conditioning (HVAC) system. One or both of the drive modules may also include a crash structure to absorb impacts. If a component of a drive module fails or is damaged, the drive module can be quickly and easily replaced with a new drive module, minimizing vehicle down time.

An apparatus for controlling a driving mode of a hybrid vehicle and a method thereof are provided in which a specific cell, which constitutes a battery, is prevented from being overdischarged by adjusting a switching time point of a driving mode (an electric vehicle (EV) mode or a hybrid electric vehicle (HEV) mode) based on a cell voltage change of the battery mounted in the hybrid electric vehicle. The apparatus for controlling the driving mode of the hybrid vehicle includes a battery including a plurality of cells, a voltage sensor to measure voltages of the cells in the battery, and a controller to control a switching time point from the EV mode to the HEV mode based on the voltages of the cells in the battery, as measured by the voltage sensor.

The present invention discloses an integrated power system and method for energy management for an electric vehicle. The system comprises a plurality of supercapacitor power packs coupled together in series and/or in parallel. The supercapacitor power packs may be integrated with an electric motor. A charge management database is configured to store data related to the charging capacity, energy requirements related to the supercapacitor power packs, and the charge cycle of each of the supercapacitor power packs with respect to consumption. A processor and a memory are coupled to the charge management database to retrieve the performance of the supercapacitor power packs. The memory comprises a plurality of modules to perform charging and/or discharging of the supercapacitor power packs. Further, a display interface displays a status of charging and/or discharging of the electric vehicle based on charge on the supercapacitor power packs.

A vehicle master device is configured to acquire update data from outside and distribute the acquired update data to a rewrite target electronic control unit (ECU). The vehicle master device includes a distribution frequency specifying unit that is configured to specify a distribution frequency of the update data to the rewrite target ECU based on a correspondence relationship between a predetermined vehicle power supply state and transmission restriction information related to distribution of the update data and a vehicle power supply state during updating, and a distribution control unit that is configured to control distribution of the update data according to the distribution frequency specified by the distribution frequency specifying unit.

A method for planning an activation action for an engine of a vehicle is disclosed. The method includes planning, according to a model, an activation action of an engine of a vehicle, and activating the engine according to the activation action. The model includes a state space comprising a current charge level of the battery and whether the engine is currently on or off. The activation action is selected from a set comprising a first action to turn on the engine to charge the battery and a second action to turn off the engine.

A method of heating an aftertreatment system includes fulfilling a vehicle drive load of a vehicle via an electrical drivetrain of a vehicle hybrid powertrain, wherein the vehicle hybrid powertrain comprises the electrical drivetrain and an internal combustion engine; while the electrical drivetrain is fulfilling the vehicle drive load, operating the internal combustion engine to generate airflow for transport of heat through the aftertreatment system; and directing a heat source to raise a temperature through a selective catalytic reduction (SCR) device of the aftertreatment system.

Systems and methods for operating a vehicle that includes an engine and an integrated starter/generator are described. In one example, torque generated via the engine is based on a requested driveline torque and a torque of an electric machine when degradation of an engine sensor is present. The torque generated via the engine may be adjusted responsive to a requested engine torque and a feedback engine torque that is based on output of an engine airflow sensor.

A vehicle controlling apparatus includes an engine processor, an electric motor, an electric power storage, an SOC detector, an internal resistance detector, and a resistance threshold setting unit. The engine processor is configured to stop an engine of a vehicle on the basis of a stop condition, and start the engine on the basis of a start condition. The engine processor is configured to prohibit a stop of the engine based on the stop condition based on determining that an internal resistance of the electric power storage detected by the internal resistance detector is equal to or greater than a resistance threshold set by the resistance threshold setting unit on the basis of a state of charge of the electric power storage, and permit the stop of the engine based on determining that the internal resistance is less than the resistance threshold.

A control system of a vehicle includes a network, a first control module, and a second control module. The first control module measures a voltage of a battery of the vehicle and supplies power from the battery to an actuator of the vehicle based on commands received via the network. The second control module is external to the first control module, transmits the commands to the first control module via the network, and, in response to diagnosing a loss of communication with the first control module, controls an alternator of the vehicle to increase the voltage of the battery. In response to diagnosing a loss of communication with the second control module, the first control module supplies power to the actuator based on predetermined data stored in the first control module.
