Driving control device, driving control method, and vehicle

Abstract

This technology provides a way to reduce the driver's discomfort with the stopping distance when a control system is implemented to start the vehicle ahead in response to the vehicle ahead starting, thereby preventing the vehicle from getting too close to the preceding vehicle. [Solution] The driving control device performs follow control in which the vehicle follows the preceding vehicle, and stops the vehicle when the preceding vehicle stops during the execution of follow control. If there is no vehicle two vehicles ahead, the vehicle stops so that the distance to the preceding vehicle becomes a first interval distance. If there is a vehicle two vehicles ahead, the vehicle stops so that the distance to the preceding vehicle becomes a second interval distance. The first interval distance and the second interval distance are different from each other. If there is a vehicle two vehicles ahead, the vehicle starts moving when the vehicle two vehicles starts moving, and after starting the vehicle, the behavior of the vehicle changes based on the behavior of the preceding vehicle.

Claims

1. A driving control device that performs follow control in which the vehicle follows a preceding vehicle, and stops the vehicle if the preceding vehicle stops during the execution of the follow control, If there is no vehicle ahead, the vehicle shall be stopped so that the distance to the preceding vehicle becomes the first interval distance. If there is a vehicle two vehicles ahead, stop your own vehicle so that the distance to the preceding vehicle becomes the second distance between vehicles. The first distance between vehicles and the second distance between vehicles are different from each other. A driving control device characterized in that, when the preceding vehicle is present, it starts its own vehicle when the preceding vehicle starts, and after starting its own vehicle, it changes the behavior of its own vehicle based on the behavior of the preceding vehicle.

2. The second distance between vehicles is longer than the first distance between vehicles. The driving control device according to claim 1, characterized in that when the distance between the vehicle and the preceding vehicle becomes less than or equal to the first distance after the preceding vehicle has started moving and the vehicle itself has started moving, the vehicle itself is decelerated.

3. The second distance between vehicles is longer than the first distance between vehicles. The driving control device according to claim 1, characterized in that, after the preceding vehicle starts moving and the self-vehicle starts moving, if the distance between the self-vehicle and the preceding vehicle becomes less than or equal to the first distance between vehicles, the self-vehicle is stopped at a third distance between vehicles that is shorter than the first distance between vehicles.

4. The driving control device according to claim 1, characterized in that, after the preceding vehicle starts moving and the vehicle in question starts moving, until the preceding vehicle starts moving, the vehicle in question is driven at a predetermined low speed.

5. The driving control device according to claim 4, characterized in that the predetermined low vehicle speed is set to 10 kilometers per hour or less.

6. A driving control method in which each step is performed in the driving control device of the vehicle itself, the vehicle itself performs follow control to follow a preceding vehicle, and the vehicle itself stops if the preceding vehicle stops during the execution of the follow control, If there is no vehicle ahead, the vehicle is stopped so that the distance to the preceding vehicle becomes the first distance between vehicles. If there is a vehicle ahead, the step is to stop the vehicle so that the distance to the preceding vehicle becomes the second distance between vehicles, If there is a vehicle ahead, the vehicle ahead starts moving when the vehicle ahead starts moving, and after starting the vehicle, the vehicle's behavior is changed based on the behavior of the preceding vehicle, including the steps of: A driving control method characterized in that the first inter-vehicle distance and the second inter-vehicle distance are different from each other.

7. A vehicle capable of performing follow control in which the vehicle follows a preceding vehicle, and performing control to stop the vehicle if the preceding vehicle stops during the execution of the follow control, Equipped with a driving control system, The aforementioned driving control device stops the vehicle so that the distance to the preceding vehicle becomes a first interval distance if there is no vehicle ahead, and stops the vehicle so that the distance to the preceding vehicle becomes a second interval distance if there is a vehicle ahead. The first distance between vehicles and the second distance between vehicles are different from each other. The aforementioned driving control device is characterized in that, when there is a vehicle ahead, it starts the vehicle when the vehicle ahead starts, and after starting the vehicle, it changes the behavior of the vehicle based on the behavior of the preceding vehicle.
