Benefits of technology

[0050]The vehicle control apparatus according to the present invention can prohibit the shutoff of the power transmission caused by the execution of reduction control performed to lower the driving force outputted from the power source, thereby preventing the vehicle from being stopped unnecessarily even when the driving force is lowered, thereby making it possible to prevent the drivability from being deteriorated.

Problems solved by technology

Therefore, there are some cases in which the simultaneous depressions of the accelerator pedal and the brake pedal as previously mentioned are apt to lead to deterioration in drivability.

first embodiment

[0061]First, the construction of a vehicle having a control apparatus according to the first embodiment of the present invention will be described with reference to the schematic block diagram of the vehicle shown in FIG. 1 and the schematic block diagram of the vehicle control shown in FIG. 2.

[0062]As shown in FIG. 1, a vehicle 10 according to the present embodiment comprises an engine 12 serving as a power source, an automatic transmission 13 that transmits a torque generated by the engine 12 and forms transmission stages corresponding to the travel conditions of the vehicle 10, a front differential mechanism 14 that distributes the torque transmitted from the automatic transmission 13 to left and right front drive shafts 22L, 22R, a rear differential mechanism 15 that distributes the torque transmitted by a propeller shaft 21 to left and right rear drive shafts 23L, 23R, a transfer 16 that distributes the torque transmitted by the automatic transmission 13 to front wheels 17L, 17...

second embodiment

[0195]Next, the following explanation will be directed hereinafter to a vehicle control apparatus according to a second embodiment of the invention. The construction of the vehicle in the present embodiment is the same as that of the vehicle 10 in the first embodiment, and thus the constituent elements of the present embodiment the same as those of the first embodiment bear the reference numerals of the present embodiment the same as those of the first embodiment in the drawings. Accordingly, the detailed explanations about the constituent elements of the present embodiment the same as those of the first embodiment will be omitted hereinafter.

[0196]The characteristic construction of the ECU 100 mounted on the vehicle 10 in the present embodiment of the invention will be described hereinafter.

[0197]The ECU 100 is operative to prohibit the automatic stopping of the engine 12 when the ECU 100 determines that the control permission conditions are established. It is therefore to be noted...

third embodiment

[0206]Next, the following explanation will be directed hereinafter to a vehicle control apparatus according to a third embodiment of the invention. The construction of the vehicle in the present embodiment is the same as that of the vehicle 10 in the first embodiment, and thus the constituent elements of the present embodiment the same as those of the first embodiment bear the reference numerals of the present embodiment the same as those of the first embodiment in the drawings. Accordingly, the detailed explanations about the constituent elements of the present embodiment the same as those of the first embodiment will be omitted hereinafter.

[0207]The characteristic construction of the ECU 100 mounted on the vehicle 10 in the present embodiment of the invention will be described hereinafter. The ECU 100 is operative to determine as an idle state the state in which the control accelerator opening degree is equal to or smaller than the idle determination value. It is therefore to be n...

Abstract

Disclosed is a vehicle control apparatus which can prevent the deterioration of drivability. The ECU can set a control accelerator opening degree to be converted when a control permission condition is established. The control accelerator opening degree is equal to or larger than an accelerator lower limit which is larger than an idle determination value for determining an automatic stopping of an engine by an eco-run. The control accelerator opening degree thus set can prevent the drivability from being deteriorated without the automatic stopping of the engine being caused even if the accelerator opening degree is converted to reduce the torque of the engine with the establishment of the control permission condition.

Description

TECHNICAL FIELD[0001]The present invention relates to a vehicle control apparatus, and more particularly to a vehicle control apparatus that controls the output of a power source.BACKGROUND ART[0002]In general, a vehicle has three fundamentally necessary abilities including a “driving force” as an ability of “advancing”, a “steering force” as an ability of “turning”, and a “braking force” as an ability of “stopping”.[0003]The “driving force” is a power, i.e., a torque generated by a power source of an internal combustion engine (hereinafter simply referred to as “engine”) in response to such an amount of depression of an accelerator pedal and transmitted through a transmission to driving wheels to be obtained as a frictional reaction force of the driving wheels and a road surface allowing the driving wheels to travel thereon. The “steering force” is obtained by a steering device capable of changing the advancing direction of, for example, front wheels in response to the operation am...
