Problems solved by technology

On a downhill slope, the movement is forward, so it is not a big problem, but on an uphill slope, the movement is backward, so sometimes it makes the driver feel uneasy

Embodiment

[0039] figure 1 It is a schematic diagram generally showing a control device for a vehicle according to an embodiment of the present invention.

[0040] exist figure 1 In , reference numeral 10 denotes an engine (internal combustion engine). The engine 10 is mounted in a vehicle 14 (the vehicle 14 is partially shown by the drive wheels 12 and the like) having drive wheels (front wheels) 12 .

[0041] The throttle valve 16 arranged in the air intake system of the engine 10 is not mechanically connected to the accelerator pedal 18 arranged on the floor of the driver's seat of the vehicle, but is connected to a DBW (Drive By Wire) composed of an actuator such as an electric motor. The mechanism 20 is connected, and the opening and closing are performed by the DBW mechanism 20.

[0042] The intake air adjusted by the throttle valve 16 flows through the intake manifold (not shown), and is mixed with the fuel injected from the injector (not shown) near the intake port of each cyl...

Abstract

Provided is a control device for a vehicle. The control device is capable of effectively performing idling stop in the case that the time of deceleration is added to the permissive condition and idling stop is allowed. The control device, allowing idling stop (stop I / S) of the vehicle when a first permissive condition comprising the stop of the vehicle is satisfied, is used for determining whether a second permissive condition that the vehicle can decelerate at below the specified vehicle speed is satisfied or not. When the second permissive condition is satisfied, an engine is allowed to perform idling stop (deceleration I / S). Furthermore, when the second permissive condition and the first permissive condition are satisfied by determination, moving determinations of the vehicle based on forward side pulse / retreating side pulse are enabled to made. For instance, at I / S of stopping, a determination is made by means of pulse at forward side pulse / retreating side. At I / S of deceleration, the determination is not made by means of retreating side pulse until the vehicle is stopped. (S300 to S310).

Description

technical field [0001] The present invention relates to a control device for a vehicle, and more specifically, to a control device for a vehicle that stops an engine from idling when waiting for a traffic light or the like. Background technique [0002] When the engine is idling stopped while waiting for a traffic light, etc., the driver may loosen the brakes and move the vehicle when the vehicle is stopped on a slope. On a downslope, the movement is forward, so there is no problem. However, on an upslope, the movement is backwards, which may give the driver a sense of uneasiness. [0003] Therefore, in the technology described in the following Patent Document 1, it is proposed that when a predetermined permission condition including that the vehicle is stopped is established and the idling stop is permitted, it is determined whether the engine is stopped, and the When the rotational speed sensor outputs more than a predetermined number of pulses (the number of pulses corre...
