Embodiment Construction

[0041] Hereinafter, embodiments of the present invention will be described with reference to the drawings. Figure 1 ~ Figure 4 It is a figure explaining the control apparatus of the vehicle which concerns on one Embodiment of this invention.

[0042] exist figure 1 In this example, a vehicle 100 runs with an internal combustion engine 110 as a driving force source. The engine 110 transmits rotational power to a continuously variable transmission (CVT: Continuously Variable Transmission) 130 through a clutch 120 disposed on one end side of an output shaft 111 to rotate the drive wheels 101 .

[0043] Engine 110 is collectively controlled by engine ECU 150 executing a control program. The engine ECU 150 is connected to a crank angle detection unit 161 , an engine rotation speed detection unit 162 , and a transmission rotation speed detection unit 163 to acquire various detection information. The crank angle detection unit 161 detects the crank angle of the engine 110 and tr...

Abstract

The present invention provides a vehicle control device which can avoid that the rotating speed of a driving force source changes greatly due to the driving of an auxiliary device at begining without needing to add a special control part, and the impact to the passengers is reduced. An engine ECU 150 controls the auxiliary device 10 carried on a vehicle 100, the auxiliary device 10 is driven by the rotation power transmitted by an engine 110, and the engine ECU 150 is equipped with a vibration detection part 153 which detects the rotating speed of the engine; and an auxiliary device turn-on determination part 153 which determines that a turn-on response signal is sent to drive the starting time of the auxiliary device when the change amount of the rotating speed of the engine detected by the vibration detection part is greater than a specified value.

Description

technical field [0001] The present invention relates to a vehicle control device that controls the drive of vehicle-mounted auxiliary equipment. Background technique [0002] A vehicle equipped with an engine as a driving force source may be equipped with auxiliary equipment such as an air conditioner and an alternator that commonly use the engine. In such a vehicle, a process of increasing or decreasing the engine torque is performed in order to suppress the influence of the load increase or decrease due to the driving of the auxiliary equipment. [0003] However, when fuel injection is stopped during deceleration or the like, the torque cannot be increased or decreased, and the load generated by the drive of the auxiliary equipment affects the rotational speed of the engine momentarily and is transmitted to the occupants as a shock. [0004] Here, Patent Document 1 proposes to control the lock-up clutch according to the rotational speed of the engine to adjust the amount ...
