摘要： Systems and methods for starting an internal combustion engine of a hybrid vehicle are presented. In one example, the internal combustion is started via closing a driveline disconnect clutch and limiting a torque output rate of an electric machine so that vehicle speed may increase continuously without decreasing during engine cranking and run-up periods.

摘要： A vehicle start-stop system includes an engine and a controller. The controller is programmed to operate the system in a first mode when a first input is selected, and in a second mode when a second input is selected. The controller is further programmed to inhibit engine stop in response to being in the first mode and an evaporator temperature having a first value, and stop the engine in response to being in the second mode and the evaporator temperature having the first value.

摘要： A vehicle includes an engine and a controller. The controller starts the engine in response to a brake status before and during a change in vehicle operating mode achieving predetermined states, and expiration of a timer initiated upon completion of the change and having a duration based upon a learned mean mode-specific shift time window. The change is initiated in response to a request to change vehicle operating mode while the engine is off.

摘要： The criteria used to determine whether to initiate an auto stop of an engine may be altered based on a number of previous auto stops of the engine, a total auto stop off time of the engine, or a total throughput of a battery. Altering the criteria may influence a frequency with which the engine is auto stopped.

摘要： An engine start using an electric motor during a vehicle travel is performed by increasing an output torque of the electric motor in a slip state where a second frictional engagement element 3 connecting the electric motor 1 and a driving wheel slips. A controller determines a requested acceleration amount from a depression amount of an accelerator pedal. When the requested acceleration amount is significant, a different torque increment characteristic is applied, compared to a case where the requested acceleration amount is not significant. Thus, the internal combustion engine starts in a high response depending on the requested acceleration amount input by the driver, thereby improving a vehicle acceleration response.

摘要： A method and a device for automatically starting an internal combustion engine having a brake pressure monitoring system and an arrangement evaluating the brake pressure with respect to its profile over time. The brake pressure gradient is evaluated when the brake pedal is released before the vehicle is restarted. If the absolute value of the negative brake pressure gradient when the brakes are released exceeds a threshold value, this upward transgression of the threshold value causes an electronic control system in the motor vehicle to restart the internal combustion engine in conjunction with a start/stop function. The main advantage which is achieved in this way is that the brake pressure gradient precedes the point at which the brake pressure reaches its position of rest so that a vehicle driver can sense the restarting of the internal combustion engine to be more spontaneous than in the prior art. With the solution according to the invention for restarting the internal combustion engine a longer period of time is available than with previously known solutions.
