Abstract

An object of the vehicle control device according to the present invention is to provide a driver with acceleration/deceleration control of a vehicle with less discomfort even in a situation where correction of measurement of an inter-vehicle distance is required due to a temperature change or the like. The present invention is a vehicle control device 100 configured to perform acceleration/deceleration control of a vehicle according to a relative speed and an inter-vehicle distance with respect to a preceding vehicle obtained from a parallax image, in which the acceleration/deceleration control of the vehicle is performed with the inter-vehicle distance being less than a certain value, the vehicle control device 100 includes correction means 230 for, in a case where the parallax image is not acquired in a correct state due to distortion due to a temperature change or an incorrect mounting position, correcting the distortion or the incorrect mounting position by the acquired parallax image, and a start timing of the acceleration/deceleration control of the vehicle is changed during a correction operation by the correction means 230.

Claims (22)

1. A vehicle control device configured to control acceleration/deceleration of a vehicle according to a relative speed and an inter-vehicle distance with respect to a preceding vehicle obtained from a parallax image,

wherein the vehicle control device is configured to control acceleration/deceleration of the vehicle with the inter-vehicle distance being less than a certain value,

wherein the vehicle control device includes a processor configured to:

in a case where the parallax image is not acquired in a correct state due to distortion due to a temperature change or an incorrect mounting position, perform a correction operation to correct the distortion or the incorrect mounting position by the acquired parallax image, and

change a start timing of the acceleration/deceleration of the vehicle during the correction operation, and

advance a deceleration start timing of the acceleration/deceleration for the vehicle during the correction operation.

2. The vehicle control device according to claim 1 ,

wherein the processor is configured to correct a measurement error in the inter-vehicle distance due to a change in direction or distortion due to a temperature change of a plurality of imaging units.

3. The vehicle control device according to claim 1 ,

wherein the acceleration/deceleration of the vehicle is switched by performing communication of the fact that a condition for permitting the correction operation by the processor is not established for a predetermined time and the correction operation is not completed in a car area network.

4. A vehicle control device configured to control acceleration/deceleration of a vehicle according to a relative speed and an inter-vehicle distance with respect to a preceding vehicle obtained from a parallax image,

wherein the vehicle control device is configured to control acceleration/deceleration of the vehicle with the inter-vehicle distance being less than a certain value,

wherein the vehicle control device includes a processor, the processor configured to:

in a case where the parallax image is not acquired in a correct state due to distortion due to a temperature change or an incorrect mounting position, perform a correction operation to correct the distortion or the incorrect mounting position by the acquired parallax image, and

change a start timing of the acceleration/deceleration of the vehicle during the correction operation by the processor,

wherein the processor is configured to obtain the parallax image by processing images obtained from a plurality of imaging units.

5. A vehicle control device configured to control acceleration/deceleration of a vehicle according to a relative speed and an inter-vehicle distance with respect to a preceding vehicle obtained from a parallax image,

wherein the vehicle control device is configured to control acceleration/deceleration of the vehicle with the inter-vehicle distance being less than a certain value,

wherein the vehicle control device includes a processor, the processor configured to:

in a case where the parallax image is not acquired in a correct state due to distortion due to a temperature change or an incorrect mounting position, perform a correction operation to correct the distortion or the incorrect mounting position by the acquired parallax image, and

change a start timing of the acceleration/deceleration of the vehicle during the correction operation by the processor,

wherein communication of a fact that the processor is performing the correction operation is performed in a car area network.
