Abstract
A following distance control device includes a vehicle speed detecting device that detects the vehicle speed VSPD of an own vehicle and outputs a vehicle speed equal to or less than a predetermined speed as zero, a following distance detecting device that detects a following distance between a preceding vehicle and the own vehicle, a first requested acceleration computing device that computes a requested acceleration GBASE from the vehicle speed and the following distance, and a stop determining device that determines the stop of the own vehicle, on the basis of a requested acceleration Greq_pre_0 kph at a time point when the output value of the vehicle speed detecting device becomes zero.
Claims9
A following distance control device comprising:
- a vehicle speed detecting device that detects a vehicle speed of an own vehicle, and outputs a vehicle speed equal to or less than a predetermined speed as zero;
- a following distance detecting device that detects a following distance between a preceding vehicle and the own vehicle;
- a first requested acceleration computing device that computes a requested acceleration from vehicle information including at least the following distance;
- a control device that controls the following distance to the preceding vehicle on the basis of the requested acceleration, and performs a stop control as the preceding vehicle stops;
- and
- a stop determining device that determines a stop of the own vehicle on the basis of a first requested acceleration at a first time point when an output value of the vehicle speed detecting device becomes zero,
- wherein the stop of the own vehicle is determined at a second time point when a time obtained by dividing a real vehicle speed at the first time point by the first requested acceleration has elapsed since the first time point.
A following distance control method comprising:
- detecting a vehicle speed of an own vehicle by using a vehicle speed detecting device that outputs a vehicle speed equal to or less than a predetermined speed as zero;
- detecting a following distance between a preceding vehicle and the own vehicle;
- computing a requested acceleration from vehicle information including at least the following distance;
- controlling the following distance to the preceding vehicle on the basis of the requested acceleration, and performing a stop control when the preceding vehicle stops;
- determining a stop of the own vehicle on the basis of a first requested acceleration at a first time point when an output value of the vehicle speed detecting device becomes zero;
- determining the stop of the own vehicle when a time obtained by dividing a real vehicle speed at the first time point by the first requested acceleration has elapsed since the first time point.
