Control device for internal combustion engine

Номер: US20120010801A1
Автор: Kaoru Ohtsuka, Kiyonori Takahashi, Naoto Kato, Shinichi Soejima
Принадлежит: Toyota Motor Corp

In a control device which uses a specific physical quantity as a control variable of an internal combustion engine, and controls the internal combustion engine by manipulation of one or a plurality of actuators, switching of setting of a manipulation variable based on a required value of a physical quantity and setting of the manipulation variables by direct instruction to individual actuators is performed without generating discontinuity in a realized value of the physical quantity. When a manipulation variable instruction value directly designating a manipulation variable of an actuator is present, the manipulation variable instruction value is converted into a value of a physical quantity which is realized in the internal combustion engine by the operation quantity instruction value. When a deviation between a physical quantity conversion value converted from the manipulation variable instruction value and the physical quantity required value is within a predetermined range, switch of information for use in setting of the manipulation variable of each of the actuators is permitted.

Precise operation of an accelerator operating member ( 7 ) is more difficult to perform in a reversing operation of a vehicle ( 1 ) as compared with an advancing operation. Therefore, behavior of the vehicle ( 1 ) is not smooth and thus tends to be unnatural. In the reversing operation of the vehicle ( 1 ), driving force output from an internal combustion engine ( 2 ) is limited in accordance with vehicle acceleration (D). At this time, it is possible to regulate the driving force of the vehicle ( 1 ) in conformity to the actual operation of the accelerator operating member ( 7 ) by the driver. In addition, limitation of the driving force is not executed in the advancing operation of the vehicle ( 1 ). At this time, the vehicle ( 1 ) can be driven in a state in which the driving force is comparatively small. Therefore, it is possible to prevent the behavior of the vehicle ( 1 ) from being unnatural. Accordingly, limitation of the driving force output from the internal combustion engine ( 2 ) can be properly carried out in accordance with the moving direction of the vehicle ( 1 ).

An output signal line connects a connection point of the signal lines and an output terminal. A first comparator circuit outputs a signal “1” when a current flowing in the line between the power supply and the connection point is larger than a normal current flowing into the ground from the power supply in a normal state. A second comparator circuit outputs a signal “1” when a current flowing in the line between the connection point and the ground is larger than the normal current. When the signal “1” is output from the first comparator circuit or the second comparator circuit, a cutoff circuit turns off a switch disposed in the output signal line.

An operator-controllable valve opens or closes an idle air bypass passage in a motorcycle, allowing an operator astride the motorcycle to set an idle position manually. A handle permits a first adjustment by the operator without use of a screwdriver or other hand tool. An additional interface enables a wider range of adjustment using a hand tool. Both interfaces vary depth of an air mixture screw of the valve within an idle air bypass passage of a throttle body. Dual cylindrical members of the valve rotate relative to one another and relative to a base of the valve, each cylindrical member driven by one of the interfaces. Locking the cylindrical members together such that both rotate in tandem upon the operator moving the handle is accomplished by either tightening the handle or tightening a nut coupling the handle to the valve. A handlebar adjustment lever may couple with the handle. 1.

A variety of skip fire engine controllers and control methods are described that utilize look-up tables, state machines, or other data structures to determine the sequence or ordering of skip-fire firings. In one aspect, a skip fire engine controller utilizes a look-up table to determine when firings are appropriate to deliver a desired engine output. In some embodiments, a firing timing controller tracks a value indicative of the portion of a firing that has been requested, but not yet directed and such information is utilized in the determination of the timing of the firings. The accumulator value is particularly useful when transitioning between different requested firing fractions.

A brake override system (BOS) ( 1 ) prioritizes braking when both an accelerator and a brake are operated simultaneously by reducing the required accelerator operation amount value that is used to control drive force so that it is lower than the actual accelerator operation amount. The BOS ( 1 ) thus achieves a balance between hill-start performance after operation by the BOS ( 1 ) is cancelled and stopping performance during operation of the BOS ( 1 ) by increasing the required accelerator operation amount value at the time at which the return of the required accelerator operation amount value to the actual accelerator operation amount is initiated when the simultaneous operation of the accelerator and the brake ends.

In response to decrease of a requested torque to a reference value or smaller, a value of a virtual air-fuel ratio that is used in calculation of a target air amount for achieving the requested torque is changed from a first air-fuel ratio to a second air-fuel ratio that is leaner than the first air-fuel ratio. The target air amount is calculated backwards from the requested torque by using the virtual air-fuel ratio. After the value of the virtual air-fuel ratio is changed from the first air-fuel ratio to the second air-fuel ratio, the target air-fuel ratio is switched from the first air-fuel ratio to the second air-fuel ratio. A target EGR rate is calculated by using the virtual air-fuel ratio. The target EGR rate is preferably determined by minimum value selection between a first target value of an EGR rate that is calculated by using the virtual air-fuel ratio, and a second target value of the EGR rate that is calculated by using the target air-fuel ratio.
