Barrier.
Illustratively,
Step S204：Judge that accelerator open degree maintains whether the time within a preset range is more than in advance by accelerator opening amount signal
If the time.
It should be noted that the fluctuation maintenance of accelerator open degree shows that accelerator open degree is constant within a preset range, for example, throttle
Aperture fluctuates in the range of 5%, shows that accelerator open degree is constant.It should be noted that above-mentioned 5% only illustrates, in reality
In the application of border, this range can be set as the case may be.
Step S205：Judge speed whether in preset vehicle speed range by speed signal.
Illustratively, preset vehicle speed range can be (30-90) km/h.
Step S206：Judge engine speed whether in the preset range of speeds by engine rotational speed signal.
Illustratively, the preset range of speeds is (1000rpm- highest empty wagons rotating speed)
It should be noted that the present embodiment does not limit the sequence that performs of above-mentioned steps S201 to S206, aforementioned four step
Suddenly it can perform, can also be performed simultaneously in any order, as long as belonging to protection of the embodiment of the present invention comprising aforementioned four step
Range.
Step S205：If clutch pedal is not operated and without clutch failure, also, brake pedal is not operated and without brake
Failure, also, accelerator open degree is more than preset value and without throttle failure, also, accelerator open degree maintains the time within a preset range
More than preset time, also, speed is in preset vehicle speed range, also, engine speed is in the preset range of speeds, then
It determines to be currently able to enter throttle automatic control mode.
Referring to Fig. 3, show another flow diagram of accelerator control method provided in an embodiment of the present invention, this method
Electronic control unit ECU is can be applied to, which can include：

Wherein, the signal of multiple characterization current vehicle conditions can include：Clutch signal, brake signal, speed signal and
One or more of engine rotational speed signal.
Step S302：Whether can currently enter by multiple echo signals and for the condition judgment that each signal is set
Throttle automatic control mode.
It is automatic by the way that whether multiple echo signals and the condition judgment set for each signal currently can enter throttle
The specific implementation process of control model can be found in above-described embodiment, and therefore not to repeat here.
Step S303：If being currently able to enter throttle automatic control mode, into throttle automatic control mode, control oil
The aperture of door is maintained at accelerator open degree corresponding with current accelerator opening amount signal.
Step S304：Into after throttle automatic control mode, throttle is sent to instrumentation by communication bus and is run
Status information, so that instrument shows the throttle information.
In the present embodiment, the message of throttle running state information, instrument can be included to instrumentation transmission by CAN bus
After table equipment receives message, throttle running state information is parsed from message and is shown, driver is set by instrument
It is standby to understand that its vehicle driven enters throttle automatic control module, door can be stepped on, also, driver passes through instrument without foot at this time
Equipment also would know that the operating status of throttle.
Step S305：Judge currently whether to need to exit throttle based on multiple echo signals for obtaining in real time and automatically control mould
Formula.
Step S306：If currently needing to exit throttle automatic control mode, throttle automatic control mode is exited, by default
Regulative mode, accelerator open degree is adjusted to target aperture.
After exiting throttle automatic control mode, it is meant that the control of throttle delivers driver, exits throttle and controls automatically
After molding formula, controllable accelerator open degree is adjusted to target aperture, specifically, can be reduced or be increased with per second 25% aperture slope
To target aperture.

In enclosing；And/or determine whether other control modes of engine are activated by engine rotational speed signal；If clutch pedal quilt
It steps on, alternatively, clutch failure occurs, alternatively, brake pedal is operated, alternatively, brake failure occurs, alternatively, gas pedal quilt
It steps on, alternatively, throttle failure occurs, alternatively, speed is not within a preset range, alternatively, the other control modes of engine are activated,
It then determines to need to exit throttle automatic control mode.
By the above process it is found that once clutch pedal is operated, clutch failure occurs, brake pedal is operated, is stopped
Vehicle failure, gas pedal be operated, throttle failure, speed occurs not within a preset range, the other control modes of engine are swashed
Any one happens in work, that is, exits throttle automatic control mode.
