A travel control device is configured to make an autonomous driving vehicle travel in such a way that the autonomous driving vehicle arrives at a specified position specified by a user who intends to board the autonomous driving vehicle, when the autonomous driving vehicle has reached a predetermined range from the specified position, transmit an information sending request notifying the user terminal that the autonomous driving vehicle has reached a vicinity of the specified position and requesting sending of position identifying information for identifying a position at which the user intends to board the autonomous driving vehicle to the user terminal via a communication circuit, and when receiving the position identifying information via the communication circuit, change a position of the autonomous driving vehicle, based on the position identifying information in such a way that the autonomous driving vehicle comes close to the user.

An on-board sensor system includes: a first sensor configured to detect a situation around a vehicle; a second sensor having a higher angular resolution than the first sensor; an acquisition unit configured to acquire a detection result of the first sensor; and a range decision unit configured to decide, based on the detection result, an observation range to be observed by the second sensor around the vehicle.

On-board sensor system

Through differentiation of input signal Vw from a sensor the angular frequency &ohgr; becomes included in the amplitude component. Through a plurality of differential operations the amplitude including the angular frequency &ohgr; varies, but the time-dependent term becomes equal. Since the amplitude of the signal Vw outputted from the revolution speed sensor is approximately constant, the angular frequency &ohgr; proportional to the revolution speed can be extracted by determining a ratio thereof.

Revolution speed detecting apparatus for extracting signal corresponding to revolution speed

An automatic steering system which reduces formation of a wheel track by changing a relative position of a vehicle with respect to a road. A reference line is provided along a road so that a vehicle moves along the reference line. The vehicle moves on the road while an amount of shift from the reference line is controlled to be equal to a target amount of shift. The amount of shift is a distance between a predetermined position of the vehicle and the reference line. A moving line of the vehicle is fluctuated with respect to time in a direction substantially perpendicular to an extending direction of the reference line. Alternatively, the reference line may be shifted in a direction substantially perpendicular to the extending direction of the reference line.

An apparatus for controlling an attitude of a motor vehicle, including a longitudinal force control device for controlling a torque of a wheel of the motor vehicle to thereby control a longitudinal force which acts in a longitudinal direction of the vehicle between the wheel and a road surface, and a tire slip angle control portion for controlling a tire slip angle of the wheel such that an absolute value of the tire slip angle is smaller when the longitudinal force control device is in operation than when the longitudinal force control device is not in operation.

Vehicle attitude control apparatus wherein tire slip angle and wheel

A system for controlling a steering angle of a vehicle, such as a steering angle of a rear steering wheel, the system having a yaw rate sensor for detecting a yaw rate of the vehicle, an actuator electrically controlled to change the steering angle of the vehicle, and a controller for controlling the actuator to control the steering angle on the basis of an input which includes at least a component derived from the detected yaw rate. The controller includes a detector for detecting an abnormality of a value of the yaw rate detected by the yaw rate sensor, and a limiter for limiting an amount of change in the steering angle to within a predetermined tolerable range when the abnormality is detected.
