Embodiment Construction

[0025] Hereinafter, a vehicle start control device and a start control method according to the present embodiment will be described based on the drawings. The same reference numerals are attached to the same components, and their names and functions are also the same. Therefore, detailed descriptions for them will not be repeated.

[0026] figure 1 It is a schematic overall configuration diagram of the vehicle 1 according to the present embodiment.

[0027] The vehicle 1 is equipped with an engine 10 as an example of a driving force source. In the engine 10, an injector 1 for directly injecting fuel into the cylinder is provided. An input shaft 42 of a transmission 40 is detachably connected to the crankshaft 11 of the engine 10 via a clutch device 20 . A propeller shaft 46 is connected to the output shaft 43 of the transmission 40 . Left and right drive wheels 49L, 49R are respectively connected to the propeller shaft 46 via a differential gear unit 47 and left and right...

Abstract

This staring control device of a vehicle 1 in which torque of a driving force source 10 is transmitted to driving wheels 49L, 49R via a clutch device 20 is provided with: a required torque acquisition unit 120 that acquires required torque of the driving force source 10; an engagement degree acquisition unit 130 that acquires the clutch engagement degree of the clutch device 20; and a starting assistance control unit 140 that, at the time of starting the vehicle 1 when the clutch device 20 is switched from a disengaged state where transmission of the torque is cut off to an engaged state where the torque is transmitted, sets the target output rotation speed of the driving force source 10 on the basis of the acquired torque required and the clutch engagement degree, and carries out starting assistance for increasing the output rotation speed of the driving force source 10 to the target output rotation speed.

Description

technical field [0001] The present disclosure relates to a vehicle start control device and a start control method. Background technique [0002] In a vehicle equipped with a manual transmission, when starting the vehicle from a stopped state, a clutch operation of gradually releasing the clutch pedal to engage the clutch is required. Therefore, when a load is applied to the engine side as the clutch is engaged, the engine stall may be caused by a decrease in the engine speed. [0003] In order to cope with such an engine stall, for example, in Patent Documents 1 and 2, a technology is disclosed that performs a start assist control based on switching from "ON" to "OFF" when the clutch pedal is released. The signal of the clutch switch is used to increase the engine speed.
