  • Patent number: 8914208
    Abstract: When the vehicle decelerates on the ascending slope, a required brake axle torque is calculated in accordance with vehicle deceleration, so that the swinging back is suppressed. At start timing after that, initial and final values of the required brake axle torque and a correction duration are determined. During the correction duration from the start timing, the required brake axle torque is decreased from the initial value to the final value. Then, based on change in a detected vehicular speed at or before a time which is a last moment of a period in which the detected vehicular speed detected based on detection signals of the wheel speed sensors are equal to or larger than a minimum detectable vehicular speed, a stop time at which an actual vehicle speed becomes zero is estimated, a period from the start time to the stop time is identified as the correction duration.

  • Patent number: 8401757
    Abstract: A running control apparatus calculates a target driving or braking torque in a calculating block to control the vehicle driven or braked by this torque at a target speed against a running resistance changed with running circumstances of the vehicle. In a control block, when a driver-required braking torque based on the braking operation of the driver is smaller than the target braking torque, the running control for the vehicle is performed to brake the vehicle by the target braking torque. When the driver-required braking torque becomes higher than the target braking torque, the running control is stopped, and the driver manually brakes the vehicle by the driver-required braking torque. When the driver-required braking torque is decreased to be lower than the target braking torque or a predetermined braking torque corresponding to the release of the braking operation, the running control is restarted.

  • Patent number: 8370042
    Abstract: A vehicle speed control device calculates a desired axle torque for maintaining a speed of a vehicle to a set speed, and conducts cruise control. Specifically, the vehicle speed control device calculates a drive force including a feedforward component corresponding to the set speed and a travel resistance against the travel of the vehicle, and a feedback component corresponding to a deviation of the set speed from the actual speed of the vehicle as a desired axle torque. The vehicle speed control device interrupts the cruise control when a requested drive axle torque requested by an accelerator operation during the cruise control exceeds the desired axle torque, and restarts the cruise control when the requested drive axle torque becomes lower than the desired axle torque.

  • Patent number: 8364368
    Abstract: A reliability for a power-train feed-forward torque may be decreased when a degree of reliability for an estimated braking torque is decreased due to disturbance factors. A power-train feedback torque is corrected based on a degree of reliability for a power-train torque, for which a reliability for a braking condition is taken into account. In a similar manner, a brake feedback torque is corrected based on a degree of reliability for a braking torque, for which a reliability for a power-train condition is taken into account. Accordingly, it is possible to compensate the decrease of reliability for the power-train feed-forward torque or brake feed-forward torque by the correction for the power-train feedback torque or the brake feedback torque.

  • Patent number: 8335626
    Abstract: An apparatus is provided for controlling acceleration of a vehicle to a target acceleration. In the apparatus, a target acceleration calculator calculates the target acceleration. A provisional acceleration setting unit sets a provisional target acceleration such that a change rate of the provisional target acceleration is limited to a target limitation value. The provisional target acceleration is used during a step during which the acceleration of the vehicle is changed to the target acceleration. A drive power calculator calculates a drive power to obtain the provisional target acceleration. In the provisional acceleration setting unit, an initial value of the provisional target acceleration depends on a running state of the vehicle.

  • Patent number: 8332117
    Abstract: An object of the invention is to provide an acceleration control apparatus, according to which accuracy for feed-forward torque may not be decreased even when a calculating accuracy for an estimated-slope torque would be decreased. Reliability of estimated slope is calculated and feedback torque is corrected, in such a manner that a gain for a feedback control portion is increased when the reliability of the estimated slope becomes lower. It is, therefore, possible to compensate a possible decrease of the accuracy of the feed-forward torque by correcting the feedback torque in accordance with the reliability of the estimated slope.

  • Patent number: 8292784
    Abstract: In a vehicle control device, a brake feedback control unit calculates a brake feedback torque Tfb-BK using a PID control model when a current state is a brake feedback use state. The brake feedback control unit stops the calculation of the brake feedback torque Tfb-BK when the current state is a brake feedback limitation state, and stores as an output value the brake feedback torque Tfb-BK that is output at a brake limitation start timing. At a brake limitation release timing, the brake feedback control unit restarts the feedback control using the stored brake feedback torque Tfb-BK as an initial value. The brake mechanism can thereby generate a predetermined brake torque of not more than 0 [N·m] immediately after the brake limitation release timing.

  • Patent number: 8214124
    Abstract: In a cruise control system for a vehicle, a cruise ECU calculates a cornering resistance applied to the vehicle based upon a steering angle, when a vehicle turns. The cruise ECU calculates a speed reduction amount as a correction vehicle speed based upon the cornering resistance. The cruise ECU subtracts the correction vehicle speed from a set vehicle speed to set a target vehicle speed so that the vehicle speed becomes lower as the cornering resistance is larger. The cruise ECU controls the vehicle speed to be within a permissible speed range of the target vehicle speed.

  • Patent number: 8204660
    Abstract: An apparatus controls automatic travel of a vehicle equipped with a motive power generator. In the apparatus, information indicating a road surface on which a vehicle is present currently is acquired. It is determined whether or not a command for shifting the vehicle from its stopped state to its traveling state is issued. When the command is issued, automatic shift of the vehicle is made from its stopped state to its traveling state by controlling drive of the motive power generator based on the acquired information. It is further determined whether or not, of a component of gravity applied to the vehicle, there is a force component applied in a direction opposite to a travel direction of the vehicle. When there is the force component, the operation applied to the motive power generator is continued even if the brake pedal is pressed by the driver.
