摘要： An electric control apparatus (ECU) permits an automatic stop of an engine if there is vehicle speed historical data after the start of the engine when a predetermined automatic stop condition is satisfied. Even if there is no vehicle speed historical data, the ECU permits the automatic stop of the engine when the shift position of an automatic transmission is the parking position. Therefore, the frequency of the automatic stop of the engine is increased, which improves fuel efficiency.
摘要翻译：如果满足预定的自动停止条件，如果在发动机起动之后存在车速历史数据，则电气控制装置（ECU）允许发动机的自动停止。即使没有车速历史数据，当自动变速器的换档位置为停车位置时，ECU允许发动机自动停止。因此，发动机的自动停止的频率增加，这提高了燃料效率。

摘要： A hybrid vehicle control apparatus is provided which can improve fuel consumption. There is provided: a cylinder cut-off determination section for determining whether all cylinders should be cut off; a cylinder cut-off cancellation determination section for determining whether cylinder cut-off cancellation conditions have been satisfied; a cylinder cut-off execution section for operating a spool valve when the cylinder cut-off determination section determines that cylinder cut-off is possible; and a cylinder cut-off control section for cutting off the cylinders of the engine based on the operating conditions of the cylinder cut-off determination section, the cylinder cut-off cancellation determination section and the cylinder cut-off execution section. When the voltage of an auxiliary battery, being the drive source of the spool valve, is at or greater than a predetermined voltage, and the oil temperature is within a predetermined range, the cylinder cut-off determination section determines that cylinder cut-off is possible.

摘要： A control system for a direct injection spark ignition engine connected to an automatic transmission that modifies engine power in accordance with a selected one of shift programs (a normal mode for improved fuel economy and a power mode for improved performance). A torque required by the engine is determined based on the detected engine speed and the engine load in accordance with characteristics corresponding to the selected shift program. And, an engine operation mode is determined to one of three modes including a stoichiometric air/fuel ratio operation mode in which a desired air/fuel ratio is set to a stoichiometric air/fuel ratio and two lean-bum operations mode in which the desired air/fuel ratio is set to be leaner than the stoichiometric air/fuel ratio. The desired air/fuel ratio is used to correct the fuel injection amount to be supplied to the engine. With this, it becomes possible to produce the acceleration as expected by the vehicle operator throughout the operating conditions with less degradation of fuel economy, when the shift program is switched to the power mode.

摘要： A method for controlling a transmission of an engine-driven vehicle having a plurality of gears, the vehicle including a service module actuable by a driver of the vehicle to select a desired gear, the service module being connected to a transmission control system which automatically changes gears in response to actuation of the service module, the vehicle further including an engine braking system connected to the transmission control system which is actuable to brake the vehicle engine during a gear change, the method comprising: monitoring the transmission input rotational speed (NE) and the transmission output rotational speed (NA); calculating a synchronous rotational speed (NE) of the desired gear; actuating the engine braking system to reduce the rotational input speed (NE) and synchronize it with the synchronous rotational speed (NS) so that the desired gear change can be effected; and disabling the engine braking system when a predetermined switch-off threshold is reached at a point in time before an expected synchronization of the rotational speeds (NE) and (NS) occurs. In one preferred embodiment, the engine braking system is disabled when the difference (DA) between rotational speeds (NE) and (NS) becomes equal to or less than a predetermined rotational differential value (DA). In another preferred embodiment, the engine braking system is disabled at a point in time which precedes the expected time of synchronization by fixed delay time (TA) which is typical for the engine braking system. By disabling the engine braking system before synchronization of the rotational speeds (NE) and (NS) actually occurs, the method accounts for hysteresis effects and the process of changing gears is speeded up.

摘要： A controller (9) estimates (calculates) an engine revolution speed of after shifting to a target gear position, based on vehicle speed and a gear ratio of an automatic transmission (3) at the target gear position. Then, the controller (9) changes the target gear position to a higher one when the calculated engine revolution speed is not less than a preset value. The controller changes the target gear position by one or more gears. Since the target gear position is raised, an engine does not overrun upon shifting down. If the target gear position is lower than a current gear position by one gear, and an engine overrun is expected, no shifting down is admitted.

摘要： A method of controlling engine torque in a motor vehicle having an internal combustion engine and multi-ratio transmission when launched from a neutral idle rest condition. At neutral idle, the transmission is controlled such that the input and output members are decoupled. During vehicle launch, two different strategies may be employed to control engine torque. One preferred method is to determine an engine brake torque limit as a function of time. Another preferred method to determine the engine brake torque limit is to estimate the torque capacity of the forward clutch at any given time using a mathematical model and a calibrated offset of turbine torque. Irrespective of the particular method used, the determined engine brake torque limit is compared to the corresponding engine torque amount that is requested by the vehicle operator. As a result, the actual engine torque output is optimized at all times to provide approximately the maximum amount of requested torque without exceeding the capacity of the transmission's forward clutch.

摘要： A system is disclosed for implementing a technique for managing torque of a drivetrain. The drivetrain includes an air intake passage having a throttle valve, an internal combustion engine having an output shaft, a transmission having an output shaft, and a rotational propulsion member operatively coupled to the transmission by a propeller shaft and a drive axle. The system includes a throttle valve sensor, an engine speed sensor, a transmission speed sensor, a vehicle speed sensor, a transmission controller, and an engine controller. The throttle position sensor provides a throttle position signal that is indicative of a rotational position of the throttle valve. The engine speed sensor provides an engine speed signal that is indicative of a rotational speed of the engine output shaft. The transmission speed sensor provides a transmission speed signal that is indicative of a rotational speed of the transmission output shaft. The vehicle speed sensor provides a vehicle speed signal indicative of a rotational speed of the rotating propulsion member. The transmission controller provides a transmission operation signal that is indicative of an operating state of the transmission. The engine controller is response to all of the signals to provide a fueling meter signal to a fueling system that is indicative of a level of fuel to be supplied to the engine. The engine output shaft generates a torque in response to the fueling meter signal that is within the torque capacity of each component of the drivetrain.
