Drive assisting apparatus

摘要

Provided is a drive assisting apparatus which assists follow-up travelling to a forward vehicle including an inter-vehicle information acquisition unit 10 that acquires a distance between a host vehicle and a forward vehicle, a deceleration unit 12 that performs a deceleration control based on the inter-vehicle distance, and a steering information acquisition unit 14 that detects steering by a driver, and the deceleration unit 12 stops the deceleration control, when the steering is detected. Therefore, it is possible to appropriately understand the will of a driver and perform a deceleration control based on the will of the driver.

主权项

1. A drive assisting apparatus which assists drive comprising:
a sensor that detects an object present in a vicinity of a host vehicle; an inter-vehicle information acquisition unit that acquires a first inter-vehicle distance between the host vehicle and a forward vehicle preceding the host vehicle in a travel lane in which the host vehicle travels; a steering angle detection unit that detects a steering angle; an operation information acquisition unit that acquires operation information relating to an operation of a direction indicator by a driver; a driver intention determination unit that determines whether the direction indicator is operated, based on the operation information relating to the operation of the direction indicator that is acquired by the operation information acquisition unit, and that determines whether the steering angle detected by the steering angle detection unit is equal to a predetermined threshold value or more; a vehicle presence information acquisition unit that acquires information as to whether a vehicle is present in a passing lane next to the travel lane based on an output of the sensor; and a deceleration unit that performs a deceleration control based on a determination of the driver intention determination unit and an output of the vehicle presence information acquisition unit, wherein the deceleration unit performs the deceleration control on the basis of the first inter-vehicle distance acquired from the inter-vehicle information acquisition unit if the driver intention determination unit determines that the direction indicator is not operated, the deceleration unit suppresses the deceleration control on the basis of the first inter-vehicle distance acquired from the inter-vehicle information acquisition unit, if the driver intention determination unit determines that the direction indicator is operated and the driver intention determination unit determines that the steering angle is not equal to the predetermined threshold value or more, until: (i) the driver intention determination unit determines that the direction indicator is not operated after determining that the direction indicator is operated, or (ii) the driver intention determination unit determines that the steering angle is equal to the predetermined threshold value or more after determining that the steering angle is not equal to the predetermined threshold value or more, and the deceleration unit stops the deceleration control if the driver intention determination unit determines that the direction indicator is operated, the driver intention determination unit determines that the steering angle is equal to the predetermined threshold value or more, and the vehicle presence information acquisition unit acquires information that a vehicle is not present in the passing lane based on the output of the sensor.
