摘要: An angular velocity sensor wherein an internal temperature of the sensor body is sensed by a temperature sensor and adjusted to be equal to a preset value; an offset value is obtained from an output of the angular velocity sensor at the preset internal temperature with no angular velocity acting thereon and an angular velocity signal at the preset internal temperature is compensated for by the obtained offset value; and also an angular velocity detection signal obtained before the internal temperature reaches the preset value is compensated for by an offset value determined on the base of a value readout from a memory table storing therein characteristic offset values varying with the internal temperature of the sensor body.

摘要: An automatic travel guiding device is a combination of a navigation control unit and automatic travel control unit that judges the position of a vehicle on a travelling road on the basis of sensed circumstances of the road extending ahead of the vehicle and correcting a current position of the vehicle to a corresponding position on the road map. The device includes means for correcting road circumstances on the basis of road data read from map-information storage medium according to the current position of the vehicle to correlatively increase both the current position accuracy and the travel control accuracy according to travel guiding instruction for following a target course preset on a road map by sensing actual road conditions and to realize automatic travel control at an increased accuracy.

摘要: An automatically driven motor vehicle is controlled to travel automatically along a predetermined running path on a road while successively detecting magnetic sources positioned along the running path with a sensor on the motor vehicle. A position of the motor vehicle on the running path is recognized based on detection of the magnetic sources with the magnetic sensor while the motor vehicle is running along the running path. A present position of the motor vehicle on the running path is estimated based on map information of the running path, which is stored on the motor vehicle, and positional information of the motor vehicle produced upon the detection of the magnetic sources before the sensor becomes unable to detect the magnetic sources, when the motor vehicle deviates from the running path and the sensor is unable to detect the magnetic sources. A steering control quantity for the motor vehicle is corrected based on a positional relationship between the present position and the running path, for thereby automatically returning the motor vehicle to the running path.

摘要: An automatically driven motor vehicle is controlled to automatically follow a front motor vehicle while controlling an intervehicular distance up to the front motor vehicle. A speed of the motor vehicle and an intervehicular distance up to the front motor vehicle are recognized, and acceleration/deceleration correcting data for the motor vehicle to adjust the recognized intervehicular distance depending on the recognized speed of the motor vehicle are generated. The acceleration/deceleration correcting data are generated based on a first correlation determined between the speed of the motor vehicle and the intervehicular distance such that the intervehicular distance increases as the speed of the motor vehicle increases when the speed of the following motor vehicle is greater than a predetermined speed. The acceleration/deceleration correcting data are generated based on a second correlation determined between the speed of the following motor vehicle and the intervehicular distance such that the intervehicular distance increases at a rate smaller than the first correlation as the speed of the following motor vehicle increases when the speed of the following motor vehicle is smaller than the predetermined speed. Acceleration and deceleration of the motor vehicle are controlled depending on the acceleration/deceleration correcting data.
