AI Technical Summary

Problems solved by technology

However, no consideration is given to the control to be performed when the vehicle accelerates suddenly
Therefore, even if the control disclosed in JPH07-139380A and JP2009-085139A is adopted, sufficient acceleration performance cannot be obtained in the case of sudden acceleration of the vehicle

Embodiment Construction

[0036] Next, an embodiment of the valve timing control device will be described with reference to the drawings. figure 1 The shown cross-sectional view schematically illustrates a configuration example of the valve timing control device according to the present embodiment. figure 2 Shown is the valve timing control along the figure 1 Sectional view of midline II-II. also, figure 2 The cross-sectional view in is a plan view schematically illustrating the state of the phase shifting mechanism 1 in one operating state. The phase conversion mechanism 1 includes a driven-side rotating member 11 and a driving-side rotating member 12 . The drive side rotary member 12 rotates synchronously with the crankshaft C of the engine E (internal combustion engine). The driven-side rotating member 11 is coaxially arranged with respect to the driving-side rotating member 12 . Further, the driven side rotating member 11 rotates in synchronization with the camshaft 10 for opening and closin...

Abstract

A valve timing control apparatus includes a driving-side rotating member (12), a driven-side rotating member (11), a fluid pressure chamber (2) defined by the driving-side rotating member and the driven-side rotating member and divided into a retarded angle chamber and an advanced angle chamber by a parting portion (13), an angle detecting portion (94, 95) detecting a relative angle of the driven-side rotating member relative to the driving-side rotating member, a fluid control mechanism (74) controlling a supply and a discharge of an operation fluid to and from the fluid pressure chamber, an acceleration operation quantity detecting mechanism detecting an acceleration operation quantity, and a control portion (8) setting either a normal drive mode or an acceleration drive mode as a control mode relative to the fluid control mechanism based on the acceleration operation quantity, and controlling the fluid control mechanism so that the relative angle corresponds to a target angle determined based on the set control mode.

Description

technical field [0001] The invention relates to a valve timing control device. Background technique [0002] Generally, the valve timing control device is configured to control the fluid control mechanism to change the amount of operating fluid in the retard chamber and the advance chamber, and in this way, change the relative angle of the driven side rotating member. According to this, the valve opening and closing timing is adjusted, so that an air amount suitable for the driving state can be supplied / discharged to the internal combustion engine. [0003] For example, a valve timing control device disclosed in JPH07-139380A includes: a variable valve timing mechanism, a driving state detecting device, a valve timing determining device, a driving control device, and a driving speed status determining device. A variable valve timing mechanism is rotationally driven to continuously vary the opening and closing timing of at least one of an intake valve and an exhaust valve. ...
