Abstract

Provided is a technique for controlling a vehicle according to a group type for a target group moving object. Provided are: a group detection unit 102 that detects a group based on signals from sensors 101; an environment information collection unit 105 that collects information on a surrounding environment of a host vehicle; a group type determination unit 103 that determines a group type based on a feature of the group detected by the group detection unit 102 and environment information collected by the environment information collection unit 105; and a risk level determination unit 104 that determines a risk level based on the group type determined by the group type determination unit 103, a speed of the host vehicle and a distance to a group moving object. A warning or vehicle control is performed based on the risk level determined by the risk level determination unit 104.

First claim

The invention claimed is:

1. A vehicle control system that controls a host vehicle based on signals from sensors, comprising:
the sensors;
a memory;
a network; and
a processor communicatively coupled to the sensors and the memory via the network, and the processor is configured to:
detect a group moving object based on the signals from the sensors;
collect information on a surrounding environment of the host vehicle;
determine a group type based on a feature of the group moving object and the environment information;
determines a risk level based on the group type, a speed of the host vehicle, and a distance to the group moving object; and

perform vehicle control of the host vehicle based on the risk level and the group type.

2. The vehicle control system according to claim 1 ,
wherein the processor determines the group type according to a width, a height, a movement, and a speed of the group moving object.

3. The vehicle control system according to claim 1 , wherein
the sensors are cameras or radars.

4. The vehicle control system according to claim 2 , further comprising
a stereo camera device,
wherein the stereo camera device includes the sensors, and the processor.

5. The vehicle control system according to claim 1 , wherein
the processor is further configured to perform a warning, and
the warning is performed using at least one of a voice, a warning sound, a warning display, and a vibration to a steering.

6. The vehicle control system according to claim 1 , wherein
the vehicle control includes at least one of braking and steering control.

7. The vehicle control system according to claim 1 , wherein
the sensors are cameras, and
the processor acquires sign information based on information from the cameras.

8. The vehicle control system according to claim 1 , wherein
a camera and a radar are used together as the sensors.

9. The vehicle control system according to claim 1 , further comprising
a vehicle communication system that performs communication between the group moving object and the host vehicle,
wherein the processor acquires information for the vehicle communication system.
