TH44688A - Engine shutdown control / automatic engine start - Google Patents

Abstract

DC60 to provide an automatic engine shutdown / start-up control system that can prevent Not to be knocked up not only in acceleration from the medium engine speed range only. But it is also in the acceleration to start the engine as well. Under "engine start and idle mode", if the engine speed Ne is in the range of 1500 rpm < Ne < 3000 rpm. , There is an acceleration by the driver And water temperature Greater than the specific value There will be a set point where the ignition is set from normal to 7 degrees under the "engine stop and start mode" if the engine speed Ne is in the range of 700 rpm < Ne < 3500. The rpm, acceleration is performed by the driver and the water temperature is greater than the specified value, the ignition setting point is further delayed from the used value while the "idle and engine ignition". It starts at 0 degrees to provide an automatic engine shutdown / start-up control system that can prevent knocking from occurring not only in acceleration from the medium engine speed range but also to accelerate to start the engine. If the engine speed Ne is in the range of 1500 rpm < Ne < 3000 rpm there is an acceleration by the driver and The water temperature is greater than the specific value. If the engine speed Ne is in the range of 700 rpm < Ne < 3500 The rpm is accelerated by the driver and the water temperature is greater than the specified value. There will be a further delay in the ignition point. From the values used at the moment "Engine start form and switch to diatomite" to start at 0 ํ

Claims (3)

1. An automatic engine shutdown / start-up device, which consists of a standard ignition-setting method that determines the engine's standard ignition point, with at least a function of the number of revolutions. Of the engine, the trajectory corrects the set point when the ignition is accelerated.For the delay, the ignition is set while the acceleration is slower than the set point, the standard ignition is set by the trajectory. The way to set the point set for such standard ignition And trajectory control points set to the ignition for performing the ignition according to the specified or modified ignition point For stopping the engine in response to a predetermined stopping condition when driving. And re-start the engine in response to a scheduled start-off operation after the engine shutdown, which has a characteristic that Trajectory corrected to the point where the ignition is set upon such acceleration will cause the amount of delay when accelerating the engine to go away from the engine stop state is greater than the amount of delay during normal acceleration. From the speed of the condition in which the engine is running When an accelerating condition is detected to delay the ignition set, the trajectory of the said ignition point, the ignition is performed to the ignition position corresponding to the amount of delay at Can be calculated by means of correcting the aforementioned ignition points And then return the engine to ignition at the ignition position calculated by the trajectory set point to such ignition. 2.Automatic shutdown / ignition control device, which consists of a standardized ignition-point trajectory that defines the engine's standard ignition point, with at least a function of the number of revolutions of engine Modified trajectory is set to ignite when acceleration is set to dampen the ignition while accelerating is slower than the standard ignition point that is defined by the set point. Provide such standard ignition And a standard ignition control method for performing the ignition on a specified or revised ignition point. For stopping the engine in response to a predetermined stopping condition when driving. And re-installed the engine In response to a predetermined driving-off reaction after the engine shutdown Which has the characteristics that Way to adjust the point set to the ignition When this acceleration is triggered, it will delay the ignition set during acceleration from the engine stop state at the point where the engine rotational speed is greater than the crankshaft speed. 3. The automatic stop / start control device as specified in Clause 1 or 2, which is unique to the kite device includes a water temperature sensor used to detect the engine coolant temperature. Where the path to fix the ignition point when there is such acceleration will adjust the ignition set point When the car is accelerated by setting the water temperature detected by the water temperature sensor. Above the temperature is determined as a condition for its operation.
