Alerting predicted accidents between driverless cars

An anti-accident device for operation onboard a host motor-vehicle, the anti-accident device comprising:

• a. a prediction-engine for processing factual input data about a plurality of motor-vehicles and computationally predicting future occurrences of motor-vehicle accidents as well as one or more parameters of the motor-vehicle accidents that are predicted to occur;
• b. a wireless transmitter for wirelessly transmitting non-visual electromagnetic (EM) signals;
• c. a wireless receiver for wirelessly receiving non-visual EM signals;
• and
• d. a device controller for sending control signals to onboard vehicle controls of the host motor-vehicle where the anti-accident device resides, wherein the anti-accident onboard device provides the following features:
• i. in response to a computed prediction by the prediction-engine that a first motor-vehicle accident will occur, where the host motor-vehicle will be hit from behind by a first external motor-vehicle, the device controller transmits an outgoing accident alert via the wireless transmitter where the outgoing accident alert comprises:
• A. the prediction that the first motor-vehicle accident will occur as computed by the prediction-engine;
• and
• B. one or more computationally predicted parameters of the first motor-vehicle accident that is predicted to occur as computed by the prediction-engine;
• and
• ii. in response to an incoming accident alert that:
• A. is received via the wireless receiver;
• B. is received from a second external motor-vehicle that is behind of the host motor-vehicle;
• C. indicates that a second motor-vehicle accident will occur behind the host motor-vehicle where the second external motor-vehicle is hit from behind by a third external motor-vehicle;
• and
• D. includes one or more parameters of the second motor-vehicle accident,
• the device controller sends control signals to one or more onboard vehicle controls of the host motor-vehicle to perform at least one vehicle control action so as to attempt at least one of the following:
• A. avoiding the host motor-vehicle being hit from behind by the second external motor-vehicle;
• and
• B. reducing damage inflicted upon the host motor-vehicle resulting from being hit from behind by the second external motor-vehicle.

An anti-accident system comprising:

• a plurality of anti-accident devices, each given anti-accident device of the plurality respectively comprising:
• a. a respective prediction-engine for processing factual input data about a plurality of motor-vehicles and computationally predicting future occurrences of motor-vehicle accidents as well as one or more parameters of the motor-vehicle accidents that are predicted to occur;
• b. a respective wireless transmitter for wirelessly transmitting non-visual electromagnetic (EM) signals;
• c. a respective wireless receiver for wirelessly receiving non-visual EM signals;
• and
• d. a respective device controller for sending control signals to onboard vehicle controls of a respective host motor-vehicle where the given anti-accident device resides,
• wherein the plurality of anti-accident devices comprises first and second anti-accident devices such that, when:
• i. first, second and third motor-vehicles are arranged relative to each other so that the second motor-vehicle is behind the first motor-vehicle and the first motor-vehicle is behind the third motor-vehicle;
• and
• ii. the first anti-accident device resides in the first motor-vehicle and the second anti-accident device resides in the third motor-vehicle,
• the first and second anti-accident devices perform the following operations:
• A. in response to a prediction-engine of the first anti-accident device computationally predicting that a specific motor-vehicle accident will occur where the first motor-vehicle will be hit from behind by the second motor-vehicle along with one or more parameters of the specific motor-vehicle accident that is predicted to occur, a wireless transmitter of the first anti-accident device wirelessly transmits, by non-visual EM radiation and from the first motor-vehicle, an accident alert comprising the prediction that the specific motor-vehicle accident will occur and the predicted one or more parameters of the specific motor-vehicle accident;
• and
• B. in response to a wireless receiving of the accident alert by the second anti-accident device on the third motor-vehicle which is in front of the first motor-vehicle, the second anti-accident device performs at least one vehicle control action at the third motor-vehicle so as to attempt at least one of the following (i) avoiding being hit from behind by the first motor-vehicle and (ii) reducing damage inflicted upon the third motor-vehicle resulting from being hit from behind by the first motor-vehicle.
