VEHICLE CRUISE CONTROL DEVICE

摘要

A vehicle cruise control device is provided that sets a traveling road that the vehicle is to travel from then based on acquired information of surroundings, and executes normal cruise control for causing the vehicle to travel along the set traveling road (S300), and when normally acquiring information of surroundings becomes impossible, the vehicle cruise control device executes interim cruise control for causing the vehicle to travel along the set traveling road (S500). The vehicle cruise control device estimates an interim travel time from when the interim cruise control starts until the vehicle completes the traveling along the set traveling road, sets a target deceleration variably so that, when the interim travel time is short, the target deceleration is higher as compared to where the interim travel time is long, and decelerates the vehicle so that a deceleration of the vehicle coincides with the target deceleration (S600).

主权项

1. A vehicle cruise control device that acquires information of surroundings of a vehicle, sets a traveling road that the vehicle is to travel from then based on the acquired information of the surroundings, and executes cruise control for causing the vehicle to travel along the set traveling road, wherein when normally acquiring information of surroundings becomes impossible, the vehicle cruise control device executes interim cruise control for causing the vehicle to travel along the set traveling road, while causing a vehicle speed to decrease,
wherein the vehicle cruise control device estimates an interim travel time from when the interim cruise control starts until the vehicle completes the traveling along the set traveling road, sets a target deceleration variably according to the interim travel time so that, when the interim travel time is short, the target deceleration is higher as compared to where the interim travel time is long, and decelerates the vehicle so that a deceleration of the vehicle coincides with the target deceleration.
