A drive control system for preventing damage from a power distribution device under a motor mode and for improving fuel efficiency. A time duration from termination of the first operating mode where a torque of the first motor is applied to the power distribution device while halting a carrier (at step S4), and a temperature of the power distribution device is estimated based on the calculated time duration (at step S13). The first operating mode is enabled if the estimated temperature is lower than a predetermined allowable temperature (at step S15), and inhibited if the estimated temperature is higher than the allowable temperature (at step S10).

Systems, apparatus and methods implemented in algorithms, hardware, software, firmware, logic, or circuitry may be configured to process data and sensory input to determine whether an object external to an autonomous vehicle (e.g., another vehicle, a pedestrian, road debris, a bicyclist, etc.) may be a potential collision threat to the autonomous vehicle. The autonomous vehicle may be configured to implement interior active safety systems to protect passengers of the autonomous vehicle during a collision with an object or during evasive maneuvers by the autonomous vehicle, for example. The interior active safety systems may be configured to provide passengers with notice of an impending collision and/or emergency maneuvers by the vehicle by tensioning seat belts prior to executing an evasive maneuver and/or prior to a predicted point of collision.

A power generation control device is provided for a hybrid vehicle that prevents discomfort to an occupant in a traveling scenario in which stops and starts are repeated. The power generation control device includes a power generation controller that selectively carries out series power generation and idle power generation. In series power generation, a first motor/generator is used as the drive source and electric power is generated in a second motor/generator by an internal combustion engine. In idle power generation, electric power is generated in the second motor/generator by the internal combustion engine while the vehicle is stopped. The power generation controller sets a series power generation start threshold of the battery at which series power generation is started, and an idle power generation start threshold of the battery at which idle power generation is started. The series and idle power generation start thresholds are the same value.

A hybrid electric vehicle system comprises an internal combustion (IC) engine and an electric engine providing power to a drive shaft of the vehicle. The IC engine receives a fuel from a fuel tank. Exhaust gases from the IC engine are treated at an exhaust treatment apparatus including a reagent tank containing a reagent. A controller monitors a quality of the fuel in the fuel tank and the reagent in the reagent tank and if needed, initiates fuel degradation reduction event or a reagent degradation reduction event. These events can include running the IC engine even if a battery supplying power to the motor is not discharged. The fuel degradation reduction event includes dosing the fuel tank with an antioxidant to reduce the rate of degradation of the fuel.

A controller for a vehicle is provided. The vehicle includes an engine, a rotary machine, at least one driving wheel, a first clutch disposed between a power transmission member and the rotary machine, the power transmission member being disposed between the engine and the driving wheel, the first clutch being configured to be switched to an engaged state or a disengaged state, and a second clutch disposed in parallel with the first clutch, the second clutch being a one-way clutch. The controller includes an electronic control unit. The electronic control unit is configured to control at least one of the rotary machine or the first clutch so as to reduce inertia of the power transmission member based on a torsional load acting on the power transmission member.

A method for operating a motor vehicle. At least one electric engine designed for driving the motor vehicle is used to recuperate electric energy. In this case, a travel of the motor vehicle during a period of time lying ahead is taken into account. During the use of at least one electric engine for recuperating the electric energy, it is taken into account whether during a thermal load of the at least one electric engine in the period lying ahead, a reduction of the power that can be output by at least one electric engine is to be expected. The at least one electric engine then recuperates an amount of electric energy during the deceleration of the motor vehicle which is smaller than the amount of electric energy that can be recuperated during the deceleration by the at least one electric engine. The invention relates in addition also to a motor vehicle.

A hybrid vehicle has a drive comprising an internal combustion engine, has an energy converter comprising an electric machine that can be operated for recuperation purposes, and has a control unit that is operatively connected to an operating element, to the drive and to the energy converter. The hybrid vehicle glides when the drive is not in the propulsion mode of operation and with an electric motor operated in a recuperation intensity stage in a first drive state. Based on the control unit having made the determination that the operating element was actuated, the determination is made in the control unit as to whether a condition is present, whereby the duration of the actuation of the operating element is determined and it is determined in a comparison that the duration is below the time threshold value. If the condition is present, a changeover is made from the first drive state to a second drive state in which the hybrid vehicle is then operated.

An ECU performs control processing including setting an inverter to a gate blocking state when an abnormal condition of the inverter occurs, activating a converter, driving an engine, carrying out first suppression control when an abnormal condition of a resolver occurs and when an MG2 rotation speed immediately before occurrence of the abnormal condition is equal to or smaller than a first speed threshold value, and carrying out second suppression control when the MG2 rotation speed immediately before occurrence of the abnormal condition is greater than the first speed threshold value and when there is no record of stop.

Systems, apparatus and methods may be configured to implement actively-controlled light emission from a robotic vehicle. A light emitter(s) of the robotic vehicle may be configurable to indicate a direction of travel of the robotic vehicle and/or display information (e.g., a greeting, a notice, a message, a graphic, passenger/customer/client content, vehicle livery, customized livery) using one or more colors of emitted light (e.g., orange for a first direction and purple for a second direction), one or more sequences of emitted light (e.g., a moving image/graphic), or positions of light emitter(s) on the robotic vehicle (e.g., symmetrically positioned light emitters). The robotic vehicle may not have a front or a back (e.g., a trunk/a hood) and may be configured to travel bi-directionally, in a first direction or a second direction (e.g., opposite the first direction), with the direction of travel being indicated by one or more of the light emitters.

Some embodiments of the present invention provide a control system configured to control a driveline of a motor vehicle to operate in a selected one of a plurality of configurations, the system being configured to receive a brake signal responsive to the application of a braking system, the system being configured to cause the driveline to operate in a second configuration and not a first configuration in dependence at least in part on the brake signal, wherein the first configuration a first group of one or more wheels and in addition a second group of one or more wheels are arranged to be driven by the driveline and in the second configuration the first group of one or more wheels and not the second group are arranged to be driven by the driveline.
