Embodiment
As shown in Figure 1, the embodiment provides a kind of accelerator control method, including：
Step 10：The first state value under current driving condition is obtained, which includes：Vehicle body acceleration value,
Suspension displacement value and suspension acceleration magnitude；
When driving, vehicle body acceleration value, suspension displacement value and suspension acceleration magnitude are obtained in real time as the first shape
State value；
Step 20：When the first state value is all higher than first predetermined value, guard mode is switched to；
Car body controller memory storage vehicle body acceleration value, suspension displacement value and suspension acceleration magnitude predetermined value as
One predetermined value, when the real-time vehicle body acceleration value got is less than the predetermined value of vehicle body acceleration value, exports A0, when getting
Real-time vehicle body acceleration value be equal to or more than vehicle body acceleration value predetermined value when, export A1；When the real-time suspension got
When shift value is less than the predetermined value of suspension displacement value, B0 is exported, when the suspension displacement value got in real time is equal to or more than suspension
During the predetermined value of shift value, B1 is exported；When the real-time suspension acceleration magnitude got is less than the predetermined value of suspension acceleration magnitude,
C0 is exported, when the real-time suspension acceleration magnitude got is equal to or more than the predetermined value of suspension acceleration magnitude, exports C1；When same
When export A1, B1 and C1 when, i.e., when first state value is all higher than first predetermined value, vehicle switches to guard mode；Collect
Vehicle body acceleration value include the cross stream component parallel with travel direction, and the longitudinal component perpendicular to travel direction；Hold sway
When road is uneven, vehicle traveling can be caused to jolt, the longitudinal component of the longitudinal vehicle body acceleration value at this moment collected is more than in advance
Definite value, exports A1；And suspension displacement value and suspension acceleration magnitude further illustrate the stable situation of the current driving of vehicle,
Vehicle traveling can just export B1 and C1 in the case of extremely jolting, and vehicle is thus switched to guard mode；
Step 30：The second state value under current driving condition is obtained, which includes：Pedal displacement value and step on
Plate acceleration magnitude；
When driving, pedal displacement value and pedal acceleration magnitude are obtained in real time as the second state value；
Step 40：When second state value is all higher than second predetermined value, fuel-economizing state is switched to；
The predetermined value of pedal displacement value and pedal acceleration magnitude is stored in car body controller as second predetermined value；When obtaining
When the real-time pedal displacement value got is less than the predetermined value of pedal displacement value, D0 is exported, when the real-time pedal displacement value got
Equal to or more than pedal displacement value predetermined value when, export D1；When the real-time pedal acceleration magnitude got accelerates less than pedal
During the predetermined value of angle value, E0 is exported, when the real-time pedal acceleration magnitude got is equal to or more than the predetermined of pedal acceleration magnitude
During value, E1 is exported；In the case where vehicle is in guard mode, when exporting D1 and E1 at the same time, and when the second state value is equal to or greatly
When second predetermined value, vehicle is switched to fuel-economizing state, under fuel-economizing state, the action dull of air throttle, and gas pedal
Pedal displacement value and pedal acceleration magnitude it is all very big in the case of, air throttle will not do the adjusting of corresponding aperture size,
But corresponding movement range can be reduced or directly ignore this trample action；Thus by the consequence stepped on by road injustice by mistake or
Loss is preferably minimized.
Wherein, vehicle can also directly acquire the open signal of guard mode, after this open signal is got, directly switch
To guard mode, without carrying out the judgement of A1, B1 and C1 again.
The embodiment of the present invention, additionally provides a kind of accelerator control device, including：First acquisition module, works as obtaining
