Vehicle control apparatus

摘要

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.

主权项

1. A vehicle control apparatus for a vehicle provided with a power source, an accelerator pedal, and a brake pedal, the vehicle control apparatus comprising:
an accelerator opening degree detection unit that detects a depression amount of the accelerator pedal as an actual accelerator opening degree; a brake detection unit that detects a depression of the brake pedal; a power transmission interruption unit that interrupts a power transmission to be transmitted from the power source to driving wheels; a permission condition determination unit that determines a control permission condition being established when the depression of the accelerator pedal is detected by the accelerator opening degree detection unit, and the depression of the brake pedal is detected by the brake detection unit; an output control unit that executes a reduction control to reduce a driving force to be outputted by the power source by converting the actual accelerator opening degree detected by the accelerator opening degree detection unit to a control accelerator opening degree at a rate of conversion corresponding to the actual accelerator opening degree while the control permission condition established is determined by the permission condition determination unit; and a power transmission interruption prohibition unit that prohibits interrupting the power transmission to be transmitted from the power source to the driving wheels by the power transmission interruption unit while the control permission condition is established, in which the power source has an engine, the power transmission interruption unit is operative to interrupt the power transmission by having the engine automatically stopped when the control accelerator opening degree is not more than an idle determination value preliminary set, and the power transmission interruption prohibition unit is operative to allow the control accelerator opening degree to be converted by the output control unit to have a value equal to or larger than accelerator lower limit value that is larger than the idle determination value, so as to prohibit the power transmission interruption unit from having the engine automatically stopped when the reduction control is executed by the output control unit.
