An engine idle reduction control apparatus includes a first data acquiring unit, a detecting unit, a first determining unit, a control unit, and a second determining unit. The detecting unit is configured to detect a traffic circle, on the basis of traveling environment data acquired by the first data acquiring unit. The control unit is configured to execute an idle reduction, in a case where the first determining unit determines that a control condition for a pre-stop idle reduction control is satisfied. The second determining unit is configured to determine whether a prohibition condition for the pre-stop idle reduction control is satisfied, in a case where the traffic circle is detected. The control unit is configured to prohibit the idle reduction even in a case where the control condition is determined to be satisfied, on a condition that the prohibition condition is determined to be satisfied.

The present application disclosed a a method and a device for controlling start-stop of a vehicle, a vehicle and an electronic apparatus. The method includes steps of: acquiring a first start-stop instruction, and determining a first start-stop type of the vehicle according to the first start-stop instruction; acquiring a second start-stop instruction, and determining a second start-stop type of the vehicle according to the second start-stop instruction; and performing start-stop controlling on an engine according to priorities of the first start-stop type and the second start-stop type. Therefore, the method can actively control the start-stop of the engine according to the priority of the start-stop type, which can well respond to the driving intention of the driver, the driving experience is improved, the start-stop time of the engine is saved, and the fuel consumption of the vehicle is greatly reduced, and the driving safety of the vehicle and the personal safety of the driver and passengers are guaranteed.

Methods and systems are provided for a start/stop feature. In one example, a method includes adjusting start/stop conditions in response to a vehicle operator customizing start/stop conditions. The vehicle operator customizes start/stop conditions for a plurality of different driving conditions.

A vehicle (1) is a hybrid vehicle including a traveling mode to travel only with the driving force of a drive motor (5). Vehicle (1) is mounted with an internal combustion engine (10) capable of being operated at an air-fuel ratio leaner than the theoretical air-fuel ratio. The operation of internal combustion engine (10) is controlled by a control unit (41). Control unit (41) is configured to determine whether to stop internal combustion engine (10) in an operation state, in consideration of the NOx adsorption ratio of a downstream-side exhaust purification catalyst (33) provided in an exhaust passage (31) of internal combustion engine (10).

A controller includes an engine controlling section and a motor-generator controlling section. The controller is configured to use the engine controlling section and the motor-generator controlling section to execute an intermittent stop control, a temperature increase control, an intermittent stop prohibition control, and a motoring control. The intermittent stop control automatically stops and restarts operation of an internal combustion engine. The temperature increase control increases the temperature of a filter in the exhaust passage to a temperature at which PM can be burned. The intermittent stop prohibition control prohibits stop of the operation of the internal combustion engine by the intermittent stop control until the temperature increase control is completed. The motoring control drives the output shaft of the internal combustion engine by the motor-generator, thereby forcibly rotating the internal combustion engine.

Systems and methods to control operation of a system based on aftertreatment interaction include a controller structured to receive one or more parameters associated with an exhaust aftertreatment system of an electric vehicle, where the one or more parameters are associated with an aftertreatment event associated with the aftertreatment system, determine an operation state of the system based on the one or more parameters, and generate a command structured to adjust operation of the system responsive to the determination of the operation state.

A method for detecting leakage of a high pressure fuel pump of a vehicle includes: turning off starting of an engine; after the starting of the engine is turned off, determining whether restarting of the engine occurs by a fuel rail pressure condition in which internal fuel pressure of a fuel rail connected between the high pressure fuel pump and an injector of the engine is less than or equal to a reference pressure; when the restarting of the engine occurs by the fuel rail pressure condition, determining whether a reference pressure reach time of the internal fuel pressure of the fuel rail is less than or equal to a reference time; and when the reference pressure reach time of the internal fuel pressure of the fuel rail is less than or equal to the reference time, storing a number of times of restarting of the engine.

Methods and systems for operating an engine with an electrically heated catalyst and an electrically driven compressor are described. In one example, the electrically driven compressor and the electrically heated catalyst are activated before an engine start so that vehicle emissions may be reduced more efficiently at engine starting and thereafter.

Methods and systems are provided for a start/stop feature. In one example, a method includes adjusting start/stop conditions in response to a vehicle operator customizing start/stop conditions. The vehicle operator customizes start/stop conditions for a plurality of different driving conditions.

Methods and systems are provided for increasing a catalyst temperature prior to entering a vehicle mode where combustion is temporarily discontinued. In one example, a method for increasing a temperature of an emission control device before a transient fuel shut-off (TFSO) event of an engine via a spark timing adjustment and an exhaust valve opening timing adjustments. Adjustments of the spark timing and the exhaust valve opening timing may change depending on whether a transient fuel shut off event of an auto-stop event occurs.
