  • Patent number: 7966127
    Abstract: The invention provides a vehicle motion control device capable of realizing optimum avoidance control in the case of an emergency. The vehicle motion control device includes an external environment detection unit for detecting external environment, and a travel state detection unit for detecting a travel state of a driver's vehicle. An obstruction is detected based on the external environment detected by the external environment detection unit, and an environment map indicating obstructions is created. A control device estimates a plurality of possible avoidance actions for avoiding an obstruction based on the environment map and the travel state of the driver's vehicle detected by the travel state detection unit. The control device estimates collision damage according to each avoidance action estimated by the avoidance action estimation unit, and selects an appropriate avoidance action based on the estimated collision damage.

  • Patent number: 4860209
    Abstract: In a running command system for an unmanned vehicle, path information is stored, a current running state is compared with running command instruction data, an end of an operation corresponding to the running command instruction data is detected, and new running command instruction data corresponding to the next operation is generated upon detection of the end of the operation. The optimal running command instruction data can be set to cause the unmanned vehicle to travel along a running path whose information is stored in a running course memory, thereby accurately guiding the unmanned vehicle to a destination.

  • Patent number: 4809178
    Abstract: An obstacle data processing system for an unmanned self-controlled vehicle, capable of enabling the vehicle to automatically avert any obstacle which lies in the course of running of the vehicle. The system has obstacle position memory device capable of accumulating position data concerning specific obstacles and, hence, forming data concerning the distribution of the obstacles. The vehicle therefore can conduct appropriate averting operation in accordance with the distribution of a plurality of obstacles.

  • Patent number: 4700302
    Abstract: An automatic guidance system for an unmanned vehicle causes the unmanned vehicle to move to a destination by a combination of traveling along a preset course, and turning and stopping at predetermined positions. A running control unit is provided to determine optimal control values in such a manner that a running state of the unmanned vehicle after a predetermined period of time is predicted by changing control values set in a drive unit in accordance with state values (e.g., position information and heading angle information) representing the current running state, and that the running state after the predetermined period of time matches with the directed operation of the unmanned vehicle, thereby accurately guiding the unmanned vehicle along the preset path.
