Embodiment Construction

[0028] Hereinafter, modes for implementing the invention will be described with reference to the drawings.

[0029] First, refer to figure 1 , 2 To carry vehicle control device 10 (refer to image 3 ) configuration of the vehicle 12 will be described.

[0030] figure 1 It is a configuration diagram showing an example of the configuration of the vehicle 12 . in addition, figure 2 It is a configuration diagram showing an example of the configuration of the brake system 16 mounted on the vehicle 12 .

[0031] Such as figure 1 As shown, vehicle 12 includes an engine 14 , a braking system 16 , and the like.

[0032] The engine 14 is an internal combustion engine that generates power by burning fuel such as gasoline or light oil. Power of the engine 14 is transmitted to drive wheels 20 via a transmission 18 . Among them, the transmission 18 is an automatic transmission with a torque converter capable of causing torque (creep torque) generated by a creep phenomenon to act o...

Abstract

The invention relates to a vehicle control apparatus. It is possible to suppress the downward movement of the vehicle on the uphill road when the engine is automatically stopped based on the idling stop control and the braking operation is released and the engine is restarted. The vehicle control apparatus includes a vehicle speed detection part, an idle stopping control part for making the engine automatically stop if the engine stopping condition including braking operation and a vehicle speed being less than or equal to a first speed is satisfied and making the engine automatically start if a condition is satisfied, including a condition that, after the engine is automatically stopped, a braking stopping operation is performed; and an uphill road determination part determining that the vehicle is on an upslope; and a brake control part automatically generating a braking force if it is determined that the vehicle is on an upslope, during a period from when the engine starting condition is satisfied to the engine starting is completed as a result of the braking stopping operation before the vehicle is stopped after the engine is automatically stopped.

Description

technical field [0001] The present invention relates to a vehicle control device mounted on a vehicle capable of executing idling stop control. Background technique [0002] Conventionally, there is known an idle stop control that automatically stops the engine of a vehicle when a predetermined engine stop condition is satisfied, and then automatically restarts the engine when a predetermined engine start condition is satisfied (for example, refer to Patent Document 1). [0003] Patent Document 1: Japanese Patent Laid-Open No. 2012-77650 [0004] However, for example, in idling stop control that stops the engine during deceleration before the vehicle stops (hereinafter referred to as deceleration idling stop control), there may be cases where the brake operation is released after the engine stops but before the vehicle stops when the vehicle is decelerated. And the case of engine restart. [0005] Here, the vehicle does not generate creep torque during the period from when...
