A vehicle controller is configured to execute a duty cycle control process of alternately repeating an electric power generation execution period and an electric power generation stop period of an electric generator and controlling a duty cycle, which is a ratio of the electric power generation execution period to a single cycle of repeated cycles, when determining that an anomaly has occurred in a driving circuit. The duty cycle control process includes at least one of two processes, a process of setting the duty cycle to be larger when a member in an overheatable region, in which overheating is possibly performed by the heater, has a low temperature than when the member has a high temperature and a process of setting the duty cycle to be larger when an internal combustion engine has a large intake air amount than when the engine has a small intake air amount.

A controller for a hybrid electric vehicle. The hybrid electric vehicle includes an engine, a motor generator, a clutch arranged between a crankshaft and the motor generator, and a catalyst arranged in an exhaust passage. The controller includes first processing circuitry that executes a catalyst warming process that warms the catalyst under a situation in which the hybrid electric vehicle is at a standstill and second processing circuitry configured to control the clutch and the motor generator. The first processing circuitry requests the second processing circuitry to prohibit disengagement of the clutch when the catalyst warming process is executed.

At least some embodiments of the present disclosure are directed to systems and methods for controlling a cylinder deactivation (CDA) operation for an electrified powertrain, the electrified powertrain comprising an engine and an additional power source, the engine having a plurality of cylinders. The method includes the step of operating the electrified powertrain in a CDA mode and deactivating one or more selected cylinders of the plurality of cylinders; receiving measurement data indicative of operating conditions of the electrified powertrain; analyzing the measurement data to determine whether a predetermined operating condition is met; and adjusting the CDA operation by adjusting the duration of the CDA operation or changing a number of deactivated cylinders.

A vehicle allocation device for allocating a vehicle in response to a vehicle allocation request from a terminal of a user includes a vehicle selection unit configured to select, from a plurality of vehicles learning a relationship between input parameters and an output parameter related to traveling, a vehicle having relatively large learning progress in the relationship between the input parameters and the output parameter, and output a vehicle allocation instruction to the selected vehicle in a case where the vehicle allocation request is received.

A vehicle system includes an engine, a transmission including a torque converter, a clutch configured to selectably couple and decouple the torque converter, and a gearset, a selective catalytic reduction (SCR) exhaust aftertreatment system. An electronic control system may be operatively coupled with the engine, the electronically controllable clutch, and the SCR exhaust aftertreatment system. The electronic control system is configured to evaluate whether an SCR catalyst temperature satisfies at least one minimum temperature criterion, in response to the SCR catalyst temperature satisfying the minimum temperature criterion, permit a neutral at stop operation wherein the electronically controllable clutch is controlled to selectably decouple the torque converter and the one or more gears at least in part in response to the vehicle system being in a stopped state, and in response to the SCR catalyst temperature not satisfying the minimum temperature criterion, prevent the neutral at stop operation.

Various embodiments include a control system for the regeneration of a particle filter in an exhaust gas flow of an internal combustion engine of a hybrid vehicle including an electric machine comprising: a particle filter; a temperature sensor measuring an actual temperature of the filter; a first heat source upstream of the filter; and a controller. The controller is programmed to: determine a temperature difference between a setpoint temperature for regeneration of the particle filter and the actual temperature of the particle filter; calculate a power output difference to be applied based at least in part on the temperature difference; and control the first heat source using the power output difference.

A vehicle includes: a motive power generating device that includes a multi-cylinder engine and outputs driving power to a wheel; an exhaust gas control apparatus including a catalyst that removes harmful components of exhaust gas from the multi-cylinder engine; and a controller. The controller is configured to, upon request for raising the temperature of the catalyst during load operation of the multi-cylinder engine, execute catalyst temperature raising control that involves stopping fuel supply to at least one of cylinders and supplying fuel to the other cylinders than the at least one cylinder, and to control the motive power generating device so as to cover a driving power shortage resulting from execution of the catalyst temperature raising control.

Systems and methods for controlling a hybrid system. For example, a computer-implemented method includes determining a system temperature zone of the aftertreatment system as being in: a first temperature zone below a first temperature threshold, a second temperature zone from the first temperature threshold to a second temperature threshold, or a third temperature zone above the second temperature threshold; determining a power demand corresponding to the operation of the hybrid system as being in: a first power demand zone if the power demand is below a power threshold, or a second power demand zone if the power demand is equal to or greater than the power threshold; and determining a control strategy based at least in part on the determined system temperature zone and the determined power demand.

A controller for a hybrid electric vehicle includes an engine ECU and a HEVECU. The engine ECU executes a partial cylinder fuel cut-off control that stops supply of fuel to one or more cylinders and supplies fuel to the remaining ones of the cylinders. Further, the engine ECU sends control information of the partial cylinder fuel cut-off control to the HEVECU. The HEVECU executes a driving force compensation control so as to compensate for, using driving force of a motor generator, a decrease in driving force of a multi-cylinder engine that results from the execution of the partial cylinder fuel cut-off control. The engine ECU prohibits the execution of the partial cylinder fuel cut-off control when an anomaly possibly occurs in the sending and receiving of the control information of the partial cylinder fuel cut-off control.

Embodiments provide a vehicle computer coupled to a vehicle. The vehicle computer may be configured to compute (e.g., generate) a first (e.g., regular, main) trajectory and a second (e.g., fail-safe, minimal risk maneuver) trajectory for the vehicle. Embodiments may provide techniques for incorporating sensor input into the response for managing a minimal risk maneuver. The low-resolution sensor data may be received from a low-resolution sensor having integrated object detection processing such as an automotive radar sensor. The safety processor may modify the second trajectory using the low-resolution sensor data to avoid any new hazards along the second trajectory. Embodiments may also provide, in addition to the low-resolution radar sensor data, pre-computed analysis of the low-resolution radar sensor data from the main processor to the safety processor to reduce the false positives (e.g., false positive object detections) along the second trajectory.
