Problems solved by technology

In Patent Document 1, there is no consideration at all whether the state of the engine is "rotating" (second coasting) or "stopped" (first coasting) from the viewpoint of battery power consumption during coasting. The conditions for ending coasting are not complete from the point of view of fuel efficiency or from the point of view of power consumption

Embodiment

[0040] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0041] figure 1 It is a schematic configuration diagram showing a main part of a control system together with a schematic diagram of a vehicle drive device 10 to which the present invention is appropriately applied. The vehicle driving device 10 includes an internal combustion engine such as a gasoline engine or a diesel engine that generates power by fuel combustion, that is, an engine 12 as a driving force source. transfer. Between the engine 12 and the automatic transmission 16, a power transmission device such as a vibration damper and a torque converter is provided, but a motor generator functioning as a driving force source may also be provided.

[0042] An alternator 22 is connected to the engine 12 via a belt or the like, and generates electricity by rotating along with the rotation of the engine 12 to charge the battery 24 . In addition, the vehicl...

Abstract

The invention relates to a driving control device of a vehicle. The upper limit of the steering angle (X) ( Judgment value α, β) setting difference, compared with the situation of ending the above-mentioned inertial travel uniformly with a certain steering angle (X), it can be compared with the power consumption generated by the action of the electric power steering system (26) Regardless of the quantity, battery (24) deterioration is suppressed and the range of steering angle (X) for performing coasting is expanded to improve fuel efficiency.

Description

technical field [0001] The present invention relates to a travel control device for a vehicle, and more particularly to a technology that enables a vehicle to perform coasting running in a state in which engine braking force is reduced compared to engine braking running, suppressing battery deterioration and further improving fuel efficiency to drive. Background technique [0002] Compared with the engine-braking running that connects the engine and the wheels, using the driven rotation of the engine to effectively drive the engine brake, in order to improve fuel efficiency by extending the driving distance, it is considered to reduce the engine braking force compared with the engine-braking running To carry out the inertia driving of driving. The device described in Patent Document 1 is an example thereof, and proposes two types of (a) first inertial travel in which the engine is stopped and (b) second inertial travel in which the engine is rotated. control mode. Specifi...
