Abstract
The invention relates to a logic control method for improving the starting performance of a vehicle, which comprises the following steps of: judging whether the vehicle is in a starting process at present or not by a starting-assisting function module according to a vehicle-speed signal, an engine rotating-speed signal, a speed-changer gear signal, an electronic accelerator-pedal opening signal and a braking signal; if so, calculating and outputting a starting-target idling-speed increment to an idle-speed control function module according to a current engine water-temperature signal, and controlling an engine by the idle-speed control function module to increase the starting-target idling-speed increment part to be used as a target idle speed in the starting process by the engine on the basis of an original target idle speed; and after the starting process of the vehicle is judged to be finished by the starting-assisting function module according to the vehicle-speed signal, the speed-changer gear signal, the electronic accelerator-pedal opening signal or the braking signal, quitting a starting-assisting function to enable the engine to be restored at the original target idle speed to normally operate. Through the control method, the engine can have a lower idling speed in an idle-speed state, and the vehicle has a higher idling speed in the starting process.
Description
Technical field
The present invention relates to a kind of logic control method that is used to improve the vehicle start performance.
Background technique
In the car load exploitation; In order to satisfy the index request of NVH performance and oil consumption; Usually can the Parking idling speed setting of motor is lower, and the power performance of motor under low idling speed is relatively poor, thus cause the vehicle start poor performance; Motor stops working easily during vehicle start, and the problem that especially the motor appearance is stopped working when uphill starting is more outstanding.
Summary of the invention
The purpose of this invention is to provide a kind of logic control method that improves the vehicle start performance, make motor when idling mode, have lower idling speed, and in the vehicle start process, have higher idling speed.
The logic control method of raising vehicle start performance according to the invention is: whether starting miscellaneous function module is judged according to GES, engine rotational speed signal, TR signal, efp aperture signal and brake signal that vehicle is current and is in the starting-up process; If; Then calculate and export a starting target idling speed increment that is used to improve starting performance to the idle speed control function module according to the present engine water temperature signal; Idle speed control function module control motor; Make motor on original target idling basis, increase the target idling of starting target idling incremental portion as starting-up process; After starting miscellaneous function module is according to GES or TR signal or efp aperture signal or the completion of brake signal judgement vehicle start process; Then withdraw from the starting miscellaneous function, make motor return to original target idling and normally move.
When following condition all satisfied, starting miscellaneous function module judged that promptly current vehicle is in the starting state:
(1) speed of a motor vehicle is less than speed of a motor vehicle limit value V
0, 0km/h≤V wherein
0≤10km/h;
(2) engine speed is greater than engine speed limit value N
0, 0rpm≤N wherein
0≤3000rpm;
(3) the TR signal is T
0, T wherein
0The expression TR is at shelves;
(4) efp aperture signal is P
0, P wherein
0The expression gas pedal is not operated;
(5) brake signal is B
0, B wherein
0The expression braking pedal is not operated.
When one of following condition satisfied, starting miscellaneous function module was promptly judged the completion of vehicle start process:
(1) speed of a motor vehicle is greater than speed of a motor vehicle limit value V
1, 5km/h≤V wherein
1≤20km/h;
(2) the TR signal is T
1, T wherein
1The expression TR is at neutral gear;
(3) efp aperture signal is P
