Vehicle control device, and vehicle control system
A vehicle control device that autonomously controls a vehicle so as not to cause rapid deceleration that leads to a deterioration in ride quality. The vehicle control device controls first and second deceleration, means that reduce a speed at a deceleration rate large than a deceleration rate of the first deceleration means. The vehicle control device includes a blind spot area detecting unit that detects a blind spot area of a sensor that recognizes an external environment, and a blind spot object estimating unit that estimates a blind spot object that is a virtual moving body hidden in the blind spot area. When a vehicle approaches the blind spot area at a speed reduced by the first deceleration means, the vehicle is decelerated by the second deceleration means when a type of a moving body detected by the sensor is different from a type of the blind spot object.
1. A control device for a vehicle comprising:
a memory;
a communication interface that is communicatively coupled to a sensor; and
a processor that is communicatively coupled to the memory, wherein the processor is configured to:
detect a blind spot area of the sensor, wherein the sensor recognizes an external environment; and
estimate a blind spot object that is a virtual moving body hidden in the blind spot area, and
when the vehicle approaches the blind spot area:
transmit a first command to a brake control device to decelerate the vehicle at a first rate, and
transmit, in response to a moving body detected by the sensor being different from a type of the blind spot object, a second command to the brake control device to decelerate the vehicle at a second rate, wherein the second rate is faster than the first rate.
2. The control device according to claim 1 , wherein the brake control device includes at least one of an engine brake a regenerative brake, or a mechanical brake.
3. The control device according to claim 1 , wherein the processor is further configured to:
estimate a type and an action of the blind spot object, based on a feature amount extracted from surrounding environment information or map information.
4. The control device according to claim 2 , wherein the processor is further configured to:
estimate a type and an action of the blind spot object, based on a feature amount extracted from surrounding environment information or map information.
5. A control system for a vehicle comprising:
a sensor that recognizes an external environment; and
a processor that is communicatively coupled to the sensor, wherein the processor is configured to:
detect a moving body near the vehicle based on an output from the sensor;
detect a blind spot area that cannot be detected by the sensor, based on output from the sensor;
estimate a blind spot object that is a virtual moving body hidden in a blind spot area adjacent to the vehicle;
generate a blind-spot-passing speed that is a speed with which the vehicle passes through vicinity of the blind spot area; and
transmit an acceleration instruction to an acceleration control device or a brake instruction to a brake control device based on the blind-spot-passing speed, and
when a type of the moving body detected by the sensor is identical with a type of the blind spot object estimated, transmit an additional instruction to the brake control device that causes the vehicle to decelerate from the blind-spot-passing speed in response to a type of the moving body detected being different from a type of the blind spot object estimated.
6. The vehicle control system according to claim 5 , wherein the processor is further configured to:
change the blind-spot-passing speed according to a type of the blind spot object estimated.
7. The vehicle control system according to claim 6 , wherein
a deceleration rate in a case of further decelerating from the blind-spot-passing speed is less than, 0.2 G.
