The present disclosure relates to a control device for a vehicle. The vehicle includes an engine as a drive source, a motor generator as a drive source, a battery for storing electric power generated by the motor generator using an output of the engine, and an exhaust treatment device provided in an exhaust passage of the engine. The control device is configured to execute a temperature rise control that increases the output of the engine and raises a temperature of exhaust gas flowing into the exhaust treatment device.

A host vehicle includes an internal combustion engine, a turbocharger in fluid communication with the internal combustion engine, a communication system configured to transmit and receive a traffic-related message, and a controller in communication with the turbocharger and the communication system. The controller is programmed to: receive the traffic-related message via the communication system; and command the internal combustion engine to increase a power output to spool up the turbocharger in response to receiving the traffic-related message. The controller is programmed to determine a number of relevant vehicles. The number of relevant vehicles is a number of vehicles that are in front of the host vehicle and behind a traffic light and affect a movement of the host vehicle toward the traffic light. The traffic-related message is a one of a vehicle message from another vehicle and/or a traffic-light message from the traffic light.

Methods and systems are provided for operating a driveline of a hybrid vehicle during conditions when a temperature of a motor/generator is increasing. In one example, a method is provided that adjusts engine speed as a function of motor/generator temperature while maintaining engine power output when driver demand wheel power is constant.

A vehicle control device controls a hybrid vehicle including: an internal combustion engine having an EGR device; an electric drive device that drives the vehicle and performs an engine-based power generation; a power storage device; and a travel route acquisition device. The vehicle include an EV drive mode and an HV drive mode. The vehicle control device is configured to: where the vehicle is started under a cold condition, calculate, based on the travel route information, an average vehicle driving power in a vehicle running section under a warm condition after the start; and limit the amount of power generated by the engine-based power generation in the cold condition to be smaller when the calculated average vehicle driving power is high than when it is low, and, during the HV drive mode after a transition to the warm condition, execute the engine-based power generation accompanied by the EGR.

A method, apparatus, and system for modifying acceleration characteristics of an electric vehicle is disclosed. A persistent input throttle command signal that starts at a first time instant is received at a vehicle control system of a first vehicle that is a first type vehicle. A transformed throttle command signal is generated based on the persistent input throttle signal and a present time at the vehicle control system. An engine operation of the first vehicle is controlled based on the transformed throttle command signal at the vehicle control system. Controlling the engine operation of the first vehicle based on the transformed throttle command signal causes the engine power output of the first vehicle to be associated with a second acceleration performance curve that is associated with a second type vehicle.

A controls system for a range-extended electric vehicle comprising an overall system control unit, an engine control module configured to control a range extender of the range-extended electric vehicle, power electronics configured to control a generator of the range-extended electric vehicle, and a supervisory control module coupled between the overall system control unit and the engine control module and the power electronics, the supervisory control module configured to receive information from the overall system control unit and provide commands to the engine control module and the power electronics.

An apparatus of controlling an engine including an electric supercharger includes: an engine to combust fuel to generate power; a drive motor to assist the power of the engine and selectively operate as a generator to generate electrical energy; a battery configured to supply electrical energy to the drive motor and to be charged by the electrical energy generated from the drive motor; a plurality of electric superchargers respectively installed in a plurality of intake lines through which an ambient air flows to be supplied to a combustion chamber of the engine; and a controller that based on a determined driving tendency, adjusts a target speed of the electric superchargers of the plurality of electric superchargers, determine a driving mode of the electric superchargers, limits a maximum output of the engine, and variably adjusts a SOC electricity-generating region where the engine charges the battery.

An operating system for an automated vehicle includes a failure-detector and a controller. The failure-detector detects a component-failure on a host-vehicle. Examples of the component-failure include a flat-tire and engine trouble that reduces engine-power. The controller operates the host-vehicle based on a dynamic-model. The dynamic-model is varied based on the component-failure detected by the failure-detector.

A system for communication between a first electric vehicle, and a second electric vehicle following the first electric vehicle on a route comprises a controller communicatively coupled to a battery associated with the second electric vehicle. The controller is configured to receive a set of first operating parameters associated with the first electric vehicle. The controller determines whether to adjust a component operating parameter of at least one component of the second electric vehicle based on the set of first operating parameters. The controller generates an adjustment command configured to adjust a component operating parameter of the at least one component responsive to the determination. The adjustment of the component operating parameter is configured to manage a state of charge of the battery associated with the second electric vehicle.
