Embodiment Construction

[0033] In the following, reference will be made to Figure 1A with Figure 1B to Figure 5 Exemplary embodiments in the present disclosure are described in detail.

[0034] Figure 1A with Figure 1B is a flowchart of an engine control method for preventing an engine stall of a vehicle on a slope road according to an exemplary embodiment.

[0035] refer to Figure 1A with Figure 1B with Figure 5 , the ECU (Engine Control Unit) 40 may initially determine whether the shift lever is switched to the N range through the shift signal of the clutch 30 (S10).

[0036] When the vehicle is stopped on a sloped road and the shift lever is shifted to N, the vehicle may be pushed backward, and then when shifted to D, a load due to the acceleration of the vehicle being pushed backward is applied to the engine. Therefore, to correspond to this, the slope angle of the sloped road may be measured using the gyro sensor 51 installed at the TCU (Transmission Control Unit) 50, and the speed ...

Abstract

The present application discloses an engine control method for preventing an engine stall of a vehicle on a sloped road, which includes the steps of: detecting whether a shift lever is in a neutral stage (N gear); measuring the vehicle speed and the slope angle of the slope road, and calculating the effect on the The load of the vehicle body on the slope road; the first acceleration of the engine to increase the engine RPM so that the engine torque is greater than the load; and the second acceleration of the engine to move the vehicle when the shift lever is moved into the drive gear stage (D range).

Description

[0001] Citations to related applications [0002] This application claims the benefit of Korean Patent Application No. 10-2015-0178047 filed with the Korean Intellectual Property Office on December 14, 2015, the entire contents of which are hereby incorporated by reference. technical field [0003] The present disclosure relates to an engine control method for preventing an engine of a vehicle from stalling on a slope, and more particularly, to an engine control method for preventing an engine of a vehicle from stalling on a slope capable of preventing a vehicle from stalling on a slope. Engine stall occurs when a vehicle parked or stopped on a slope begins to drive. [0004] In particular, the present disclosure relates to an engine control method for preventing an engine when a driver mistakenly switches a gear to neutral and then switches a gear to a driving gear when a driver maintains a braking stop state on a slope road A stall of the vehicle's engine occurs as a result...
