  • Publication number: 20240101084
    Abstract: A motion manager mounted on a vehicle includes a processor. The processor receives, from an application that has determined that another object will collide with the vehicle, a motion request indicating that an additional braking force is needed, when the vehicle is stopped. The processor generates an instruction value for causing a brake device to generate a greater braking force than before the motion request is received, when the motion request indicating that the additional braking force is needed is received.

  • Patent number: 11285809
    Abstract: Disclosed is a travel control apparatus for a four-wheel drive vehicle in which the states of engagements between a drive output part for secondary drive wheels and left and right secondary drive wheel axles are each changed to a torque transmission state or a torque transmission interruption state. The ratio of rotational speed of the drive output part to the average of rotational speeds of primary drive wheels is greater than 1. When the engagement states corresponding to the secondary drive wheels on the outer and inner sides of a turning locus have been set to the torque transmission state and the torque transmission interruption state, respectively, the engagement state having been set to the torque transmission state is changed to the torque transmission interruption state upon determination that an accelerator pedal is not operated and the magnitude of lateral acceleration is equal to or greater than a predetermined threshold.

  • Patent number: 11155162
    Abstract: Disclosed is a travel control apparatus applied to a vehicle which includes two coupling apparatuses individually changing coupling torques between a drive output part for secondary drive wheels and left and right secondary drive wheel axles and in which the ratio of rotational speed of the drive output part to the average of rotational speeds of primary drive wheels is greater than 1. The apparatus generates a yaw moment in a turning direction by using driving force. When a demand of further increasing the yaw moment arises, the control apparatus renders the braking force of the primary drive wheel on the turning locus inner side coincident with a target braking force changing with the travel state of the vehicle and decreases the coupling torque of the coupling apparatus corresponding to the secondary drive wheel on the turning locus outer side. As a result, generation of an anti-spin moment is avoided.

  • Patent number: 10086669
    Abstract: Left and right stabilizer bars are provided between left and right wheels of a vehicle. A control unit controls an actuator to control a rotation angle of the right stabilizer bar with respect to the left stabilizer bar. The control unit determines whether the vehicle is moving, whether a vehicle speed is less than a first threshold value, and whether a vehicle state is in transition from a moving state to a stopped state. A detection unit detects a control amount of the actuator. When the vehicle is moving, the vehicle speed is less than the first threshold value, the vehicle state is in transition from the moving state to the stopped state, and the control amount of the actuator is greater than zero, the control unit decreases the control amount of the actuator such that the control amount of the actuator becomes zero before the vehicle speed becomes zero.
