Communication interface for start-stop systems and methods
Systems and methods for implementing a start-stop feature on a vehicle powered at least in part by an internal combustion engine include receiving, at an electronic control unit (ECU) of the vehicle, an indication that the vehicle is in line at a drive-thru; determining, by the ECU, a number of startstop events anticipated during the drive-thru; determining, by the ECU, an approximate stop time for each of the number of start-stop events; determining, by the ECU, that a battery of the vehicle has enough remaining charge to power a plurality of vehicle components during implementation of the start-stop feature; implementing, by the ECU, the start-stop feature in which the internal combustion engine is turned off for at least a portion of the time when the vehicle is stopped
Control apparatus for power supply system
In a control apparatus mounted in a vehicle supporting start-stop control, for controlling a power supply system, a target charge level setter variably sets a target charge level of a second rechargeable battery when an internal-combustion engine of the vehicle is operating. The target charge level setter sets the target charge level to a higher level as load current increases, and when setting the target charge level, performs at least one of subtracting a first load quantity indicative of a current that is supplied to first electrical loads from a detected value of the load current and adding a second load quantity indicative of a current that is supplied to second electrical loads to the detected value of the load current. The first electrical loads operate when the internal-combustion engine is operating, and the second electrical loads operate when the engine is not operating.
Heating element operation and engine start-stop availability
A vehicle includes a rear visibility component having a heating element. The vehicle further includes an engine and at least one controller programmed to auto-start and auto-stop the engine. The at least one controller is programmed to inhibit the auto-stop of the engine in response to receiving an auto-stop request while the engine is on and the heating element has been operating less than a predetermined time. In some configurations, the at least one controller is programmed to auto-start the engine and operate the heating element at a full power level in response to expiration of a time period that began with an auto-stop of the engine that occurred after the engine auto-stop was inhibited.
COMMUNICATION INTERFACE FOR START-STOP SYSTEMS AND METHODS
you and a Systems and methods for implementing a start-stop feature on a vehicle powered at least in party by an internal combustion engine are described. The method includes receiving, at an electronic control unit (ECU) of the vehicle, an indication that the vehicle is in line at a drive-thru. The method further includes determining, by the ECU, a number of start-stop events anticipated during the drive-thru. The method includes determining, by the ECU, an approximate stop time for each of the number of start-stop events. The method further includes determining, by the ECU, that a battery of the vehicle has enough remaining charge to power a plurality of vehicle components during implementation of the start-stop feature. The method includes implementing, by the ECU, the start-stop feature in which the internal combustion engine is turned off for at least a portion of the time when the vehicle is stopped.
Fuel control apparatus for vehicle and fuel control method for vehicle
A fuel control apparatus for a vehicle, having an electric pump configured to have electric power supplied, to supply fuel from a fuel tank to an injector of an internal combustion engine through a fuel pipe, and a control unit configured to have the internal combustion engine stop automatically when a first predetermined condition is satisfied, and after having the internal combustion engine stop automatically, start automatically when a second predetermined condition is satisfied, includes an operation unit configured, when the control unit has the internal combustion engine stop automatically, to supply electric power from a predetermined electric power supply apparatus to the electric pump, to have the electric pump operate.
Power transmission apparatus
The power transmission apparatus may include a battery, a motor generator that is switchable between a driving state and a power generation state, at least a load, an inverter to switch the motor generator to any of the driving state and the power generation state, a charging state detecting means to detect a charged amount C of the battery, an absorbing horsepower detecting means to detect the absorbing horsepower Lp of the load, and a control device to switch the motor generator to any of the power generation state and the driving state by means of the inverter, based on the absorbing horsepower Lp detected by the absorbing horsepower detecting means and the charged amount C of the battery that is detected by the charging state detecting means.
