  • Patent number: 11987177
    Abstract: A travel controller recognizes an action of a driver of a vehicle from image data of the driver. The travel controller obtains information indicating that determination of whether autonomous driving of the vehicle is permissible cannot be given. When the information indicating that determination of whether the autonomous driving of the vehicle is permissible cannot be given is obtained, the travel controller operates a human interface to request the driver for an instruction to drive the vehicle. The travel controller determines whether the driver is giving an instruction to drive the vehicle from an action of the driver recognized in response to the request for an instruction to drive the vehicle. When determined in the determination process that the driver is giving an instruction to drive the vehicle, the travel controller operates a drive system of the vehicle to permit autonomous driving of the vehicle.

  • Patent number: 9796410
    Abstract: A motor controller has an assist controller that generates an assist instruction AC to generate an assist torque for lightening a steering load based on a detected value of a steering torque, and a follow controller obtaining a target value of a physical quantity regarding a steering operation and generating a follow instruction TC of a follow control. Further, an intervention detector in the motor controller detects an intervention of a driver or of a system, and a restrictor restricts an internal value that is used by the assist controller or by the follow controller, so that a ratio of the assist torque against the automatic steering torque is changed, which makes it possible to switch a control to the driver or to a system without a causing a wrong feeling to the driver.

  • 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: 8694209
    Abstract: A vehicle motion controlling apparatus has an allocating unit for selecting steering or braking control mainly performed in cooperative control, receiving a desired value of vehicle turning motion, allocating steering and braking controls for the motion, determining main yaw rate from vehicle conditions, and determining a non-main yaw rate from difference between the desired value and the main yaw rate. Setting units set assist torque corresponding to the main yaw rate and braking torque corresponding to the non-main yaw rate when the steering control is selected and set braking torque corresponding to the main yaw rate and assist torque corresponding to the non-main yaw rate when the braking control is selected. The assist torque is generated for assisting a change of steering angle of vehicle in steering control. The braking torque is generated for applying braking force to wheel of vehicle in braking control.

  • Patent number: 8666563
    Abstract: A determination apparatus is provided which is installed in a vehicle. A longitudinal acceleration calculation unit obtains acceleration applied in the longitudinal direction of the vehicle, removes an acceleration component corresponding to gravity from the acceleration, and regards the resultant value as longitudinal acceleration. A selection unit selects criteria data, when considering a first case where the absolute value of the longitudinal acceleration is a first value and a second case where the absolute value is a second value larger than the first value, so that a range of accelerator-opening variation by which occurrence of an erroneous application of the accelerator is determined or a range of accelerator-opening by which the occurrence is determined in the second case becomes larger than that in the first case. A determination unit determines the occurrence by applying the current variation in the accelerator-opening or the current accelerator-opening to the selected criteria data.

  • Publication number: 20130231812
    Abstract: When it is determined that a negative pressure is insufficient, an EGR-close control is executed so that an EGR valve is driven toward a close position to increase the negative pressure in an intake passage. After that, it is determined whether the negative pressure detected by a pressure sensor is restored to a specified target negative pressure. When the negative pressure is not restored to the target negative pressure even when a specified time period has elapsed after it is determined that the negative pressure is insufficient, an automatic brake unit executes a braking-force assist control to assist a braking force of a brake. A shortage of the braking force due to an insufficient negative pressure is compensated by the braking force generated by the automatic brake unit.
