    摘要： A vehicular vibration damping control apparatus calculates a correction torque to suppress vehicle body sprung vibration. In outputting a correction torque command to a driving/braking torque producing device, the control apparatus outputs a hunting time correction torque command smaller than a normal time correction toque command when a state in which amplitude of the correction torque is greater than or equal to a predetermined amplitude continues for a predetermined time length, and thereafter to return an output of the correction torque command from the hunting time correction torque command to the normal time correction torque command if a state in which the amplitude of the correction torque is smaller than or equal to the predetermined amplitude continues for a first predetermined time length. The frequency of performing the vibration damping control is increased by suppressing occurrence of hunting at the time of return to the normal vibration damping control.

    摘要： The drive torque of a motor for driving a vehicle wheel, as shown in (a), during the period between the start of steering t1 and an instant t2 when a prescribed interval TM1s has passed, is controlled so as to be a value which is temporarily increased from the intended motor torque by just the amount indicated by the solid line waveform in (a); and during the period between t2 and an instant t4 when a prescribed interval TM2s has passed, the drive torque of a motor for driving a vehicle wheel is controlled so as to be a value which is temporarily decreased from the intended motor torque by just the amount indicated by the solid line waveform in (a). In the t1 - t2 interval (initial stage) of (c), the turning moment becomes large according to the difference between the turning moment of the turning direction of the outer wheel Mout and the turning moment (restoring moment) of the turning direction of the inner wheel Min. The increment in the yaw rate promptly rises in the initial stage of the instant t1 - t2 as indicated by a solid line in (b), in accordance with the increase in the apparent lateral force caused by the increase in the turning moment, thus the yaw rate is caused to rise without delay, and thereby it is possible to greatly improve the steering response (initial turning characteristics) of the vehicle.

    摘要： The vehicle control device (1) sets a region including a stationary object on a road defined within a predetermined distance from the stationary object along an extending direction of the road, calculates a passing position at which a host vehicle and an oncoming vehicle pass each other in accordance with a velocity of the host vehicle and a position and a velocity of the oncoming vehicle, calculates a first score that is a larger value as the velocity of the oncoming vehicle is greater, calculates a second score that is a larger value as an acceleration rate of the oncoming vehicle is greater, integrates the first score with the second score so as to calculate an integration score, and causes the host vehicle to decelerate when the integration score is greater than or equal to a predetermined value or causing the host vehicle to keep the velocity or accelerate when the integration score is smaller than the predetermined value in a case in which the passing position is present within the region.

    摘要： A correction torque command is outputted to a driving/braking torque producing means, in accordance with a correction torque to suppress a vehicle body sprung vibration. When the amplitude of the correction torque is continuing to be greater than or equal to a predetermined amplitude continues for a predetermined time length, a control apparatus outputs a hunting time correction torque command smaller than a normal time correction toque command. Thereafter, when a state of the amplitude of the correction torque being smaller than or equal to the predetermined amplitude continues for a first predetermined time length, the control apparatus returns the output of the correction torque command from the hunting time correction torque command to the normal time correction torque command. Furthermore, the control apparatus continues the output of the hunting time correction torque command if the state in which the amplitude of the correction torque exceeds the predetermined amplitude continues for the predetermined time length, before the expiration of the first time period. The apparatus can restrain the hunting at the time of return to the normal damping control and thereby improve the frequency of carrying out the damping control.

    摘要： Risk and/or control are presented in such a way that the vehicle driver can easily comprehend the fact. Upon detecting risk during driving a vehicle, the vehicle is controlled and information of at least one of the risk and the status of the vehicle being controlled is presented in visual form. In addition, the driver's initiative (D) in the vehicle is calculated (step 52), and the visual form, in which the information is presented, is altered depending on the calculated driver's initiative (step S3). When, for example, a lane departure prevention control works, the status of restraining lane departure is presented by auow(s) in an anti-lane-departure direction opposite to the direction of lane departure, The size (including the length and the width) and color of the arrow(s) are altered depending on the initiative (D). Here, When the initiative (D) is at a low level, the arrow(s) is set in color, for example, 'red' and increased in size because the risk that the tendency of lane departure may increase becomes high.
