Abstract

The present invention provides a driving assistance device for a vehicle, which can appropriately improve the judgment accuracy of traffic flow, so as to perform effective driving control to avoid or eliminate traffic jams. The driving assistance device of the vehicle of the present invention includes: a judging mechanism, which judges the state of the traffic flow on the driving route on which the own vehicle is traveling according to the acceleration of the own vehicle and the inter-vehicle distance between the own vehicle and other vehicles around it; the driving control mechanism , which controls the running of the own vehicle, and can switch the driving control mode according to the judgment result of the judging mechanism. The travel control means switches the travel control mode when the determination result indicates that the state of the traffic flow is a critical state existing during transition from the state of free flow to the state of mixed flow. Among them, the free flow state is a state in which traffic jams are less likely to occur, and the mixed flow state is a state in which both the braking state and the accelerating state of the vehicle are combined.

Description

technical field [0001] The present invention relates to a driving assistance device (driving assistance control device) for a vehicle. Specifically, the driving assistance device has the function of judging the traffic speed based on the acceleration of the own vehicle and the inter-vehicle distance between the own vehicle and other vehicles. According to the state of the flow, the driving control (mode) of the vehicle is switched according to the judgment result. Background technique [0002] In the prior art, there is a driving control device for suppressing or avoiding traffic jams. For example, the following content is described in Patent Document 1: that is, the driving control device acquires the traffic state including the traffic density on the road on which the vehicle travels, and performs driving control on the vehicle according to the acquired traffic state, and the traffic density on the road The closer to the critical density, the less likely the inter-vehicle...
