A control apparatus for performing travel control of a vehicle comprises a sensor configured to detect a state around the vehicle, and a travel controller configured to perform travel control for automated driving based on a detection result of the sensor. The travel controller is configured to, in a case where a predetermined condition is satisfied, select a target stop position located in a latitudinal direction with respect to a direction in which the vehicle moves, according to selection criteria, and to stop the vehicle at the target stop position. The selection criteria include a comparison between a speed of the vehicle and a threshold speed.

Vehicle, apparatus for controlling same, and control method therefor

An external-world recognition system includes: a satellite positioning device that measures the position of a vehicle by receiving radio waves transmitted from artificial satellites; a yaw rate sensor that detects or estimates the movement of the vehicle; a camera that acquires external-world information about the surroundings of the vehicle; and an external-world recognition device that recognizes external-world information considering a reference direction as the center. The external-world recognition device corrects a detection value from the yaw rate sensor on the basis of time-series positions of the vehicle as measured by the satellite positioning device and corrects the reference direction on the basis of the corrected detection value.

External-world recognition system

The present invention provides a vehicle control apparatus for controlling traveling of a vehicle, the apparatus comprising: a stop control unit configured to move the vehicle in a vehicle width direction and stop the vehicle in a traveling state; a notification unit configured to make a notification of the stop of the vehicle; and a change unit configured to change a notification method by the notification unit in accordance with a stop mode of the vehicle stopped by the stop control unit.

Vehicle control apparatus, vehicle, and control method

A surroundings recognition unit recognizes the road environment and traffic participants around the host vehicle. A condition satisfaction determination unit determines whether or not first to fifth conditions are satisfied, on the basis of recognition results from the surroundings recognition unit. When causing the host vehicle to travel in a lane of a traveling road adjacent to the edge of the traveling road, a control unit changes travel control content and/or notification control content relating to automated driving, depending on whether or not the first to fifth conditions are satisfied.

Vehicle control device

This vehicle control device comprises an autonomous driving control unit which automatically controls the stopping of a vehicle. If it is determined by a crossing determination unit that there is no crossing, the autonomous driving control unit controls the stopping of the vehicle so that the vehicle is stopped at a standard target stop position corresponding to a stop line on the basis of the positional information of the stop line, whereas if it is determined by the crossing determination unit that there is a crossing, the autonomous driving control unit controls the stopping of the vehicle so that the vehicle is stopped at a position before the standard target stop position on the basis of the positional information of the stop line.

Vehicle control device and vehicle control method

Even in the case that a learning flag and an ACC permission flag are not set, if a power switch is in an ON state, a travel control of a second control state, which is capable of being executed in a setting in which an inter-vehicle distance setting is a short setting or a host vehicle velocity setting is a low setting, is carried out.

Vehicle control apparatus

A travel control apparatus for controlling travel of a vehicle, comprises: an acquisition unit configured to acquire external information using one of a first camera and a second camera; a specifying unit configured to specify a position of the vehicle; and a travel control unit configured to control the travel of the vehicle based on the external information acquired by the acquisition unit and the position of the vehicle specified by the specifying unit. If the acquisition unit acquires the external information using the second camera instead of the first camera, the travel control unit controls the travel of the vehicle so that participation of a driver in driving is higher than in a case in which the acquisition unit acquires the external information using the first camera.

Travel control apparatus, travel control method, and non-transitory computer-readable storage medium

A vehicle motion determining unit determines a value indicative of a motion of the vehicle that occurs in the vehicle transverse direction of a host vehicle, on the basis of a planned travel trajectory generated by a trajectory generating unit at a time of making a lane change. The grasping request unit outputs a grasping request to the notification control unit to request grasping of the steering wheel in the case that the value indicative of the vehicle motion is greater than or equal to a predetermined value.

A vehicle operation setting unit determines vehicle operations of a host vehicle. When a course change is performed, the vehicle operation setting unit sets values (at least one of target values for a velocity, an acceleration/deceleration, a curvature, a yaw rate, a steering angle, and a lateral G force) to be less than or equal to upper limit values thereof. The vehicle operation setting unit causes the upper limit values to differ between a case in which a preceding vehicle is recognized by an external environment recognition unit, and a case in which a preceding vehicle is not recognized by the external environment recognition unit.

An electric power steering device provides an appropriate power assist from the motor even when torque sensors have failed and the steering torque is no longer detected. If an error is detected in a torque sensor, the motor is driven based on the rotor rotation angle detected by a resolver and assist characteristics. When the absolute value of the rotor turning angle velocity calculated based on the rotor rotation angle falls to or below a prescribed value, a process is started for reducing the current driving the motor, and if the state in which the absolute value of the rotor turning angle velocity has fallen to or below the prescribed value continues over a prescribed length of time, the process for reducing the current is interrupted and, because an assist current was flowing at said time of interruption, an appropriate power assist can be given during a steering retention period.

Electric power steering device

Disclosed is an idle stop control device capable of relieving reaction force (kickback) of a handle occurring at idle stop controlled by the control of the idle stop control device. Specifically, an EPSECU () detects the rotational speed of an electric motor by detecting the rotational angle (&#x3b8;) of the electric motor using a resolver (), and at the same time, detects the steering torque using a torque sensor (). Subsequently, the EPSECU determines whether or not the rotational speed of the electric motor and the steering torque are inside an idle stop transition area (P) by referring to a table () stored in a memory () in advance. When either or both of the rotational speed of the electric motor and the steering torque are outside the idle stop transition area (P), a signal requesting the prohibition of idle stop transition is output to an idle stop control device () via a cable (). Upon receiving the signal requesting the prohibition of idle stop transition, the idle stop control device () prohibits the control of transition to idle stop even when conditions for idle stop are met.

Idle stop control device

Disclosed is an electric power steering device capable of applying a prescribed steering assist force to a steering assembly, even when a torque sensor is out of order and the electric power steering device is in a state of being unable to sense steering torque by the torque sensor. Using an angle of rotation of a rotating element, which is detected by a resolver that serves as a rotating element angle of rotation sensing unit of a motor, a steering angle and a steering angular velocity are estimated, and a prescribed steering assist force is applied to a steering assembly by the motor, on the basis of an estimated steering angle and/or an estimated steering angular velocity.

An electric power steering apparatus detects, as an abnormal phase, a phase other than a combination of phases whose interphase voltage is of nearly zero volts if a q-axis current is equal to or smaller than a first threshold value though a q-axis voltage is being applied. Alternatively, the electric power steering apparatus calculates a base electric angle at which the q-axis current is equal to or smaller than a third threshold value though the q-axis voltage is being applied, and determines an abnormal phase based on the base electric angle.

Electric power steering apparatus

An electric motor is driven with high output at the time of low-speed running, and a steering at a high resolution is enabled at the time of fast-speed running. An electric power steering device causes the electric motor to generate auxiliary torque in accordance with the largeness of steering wheel torque by the steering operation of a wheel made by a driver and reduces the steering wheel torque to the driver. A control device drives, based on a vehicle-speed signal (Vs) from a speed sensor, the electric motor with high output at the time of low-speed running, and enables steering at a high resolution at the time of fast-speed running without increasing an electric-motor output.

The rotation angle detection device detects the rotation angle of a rotary member by employing, at the least, either a sine wave signal or a cosine wave signal that is generated as the rotary member is rotated, and employs a change per unit time in the sine wave signal or cosine wave signal to determine whether an output abnormality has occurred in the rotation angle detection device. Further, this rotation angle device is employed to detect the motor angle of an electric power steering apparatus.
