  • Patent number: 11326691
    Abstract: A belt-type continuously variable transmission includes a primary pulley, a secondary pulley, and a belt wound around the primary pulley and the secondary pulley. A controller performs a process, when performing a low speed position return shift to shift a transmission ratio toward a lowermost speed position while a vehicle is decelerating. The process includes: calculating a primary pressure actual lower limit, at which the belt actually starts to slip, based on the transmission ratio and a deceleration of the vehicle; setting a lower limit of a setpoint of the primary pressure to the primary pressure actual lower limit; setting the primary pressure actual lower limit higher with a locking tendency of a vehicle wheel detected than that without the locking tendency detected; and setting the primary pressure actual lower limit with the locking tendency detected to increase as the transmission ratio varies toward the lowermost speed position.

  • Patent number: 11325600
    Abstract: The present invention provides a vehicle control method capable of suppressing an increase in the frequency of stopping and restarting of the engine when the braking device is activated at the self-driving mode. When the operation mode is set as self-driving, the braking device is activated in accordance with a system deceleration request to keep an actual vehicle-speed at a target vehicle-speed or change the actual vehicle-speed at the target vehicle-speed or lower depending on environment surrounding the vehicle. Further, a braking amount is estimated, the braking amount is a magnitude of a braking force generated from the activated braking device. When the braking amount is an engine-stopping enabling threshold or more, enabling stopping is allowed. When the braking amount is less than the engine-stopping enabling threshold, enabling stopping is not allowed.

  • Patent number: 11307585
    Abstract: A first method includes detecting, based on sensor data, an environment state; selecting an action based on the environment state; determining an autonomy level associated with the environment state and the action; and performing the action according to the autonomy level. The autonomy level can be selected based at least on an autonomy model and a feedback model. A second method includes calculating, by solving an extended Stochastic Shortest Path (SSP) problem, a policy for solving a task. The policy can map environment states and autonomy levels to actions and autonomy levels. Calculating the policy can include generating plans that operate across multiple levels of autonomy.

  • Patent number: 11305768
    Abstract: An acceleration rate is controlled so that a vehicle speed during autonomous driving is caused to approach a target vehicle speed. When a host vehicle has caught up with another vehicle traveling ahead of the host vehicle, the vehicle speed of the host vehicle is limited in accordance with a headway distance to the other vehicle. An acceleration rate is changed in accordance with a frequency with which the host vehicle catches up to a preceding vehicle, which is another vehicle immediately ahead of the host vehicle, and to another vehicle ahead of the preceding vehicle.

  • Patent number: 11305757
    Abstract: A method performs autonomous travel control of a subject vehicle to a target stop position on the basis of a remote operation command from a remote operation device. The subject vehicle has an autonomous travel control function and an automatic locking/unlocking function for a vehicle door. The autonomous travel control is executed under a precondition that a locking/unlocking device for the door is unlocked. The method includes prohibiting the automatic locking/unlocking function from locking the door while the vehicle is executing autonomous travel control; detecting a distance between the vehicle and the remote operation device when the vehicle stops at the target stop; setting a temporal interval from when the vehicle stops until the locking/unlocking device for the door is locked using the automatic locking/unlocking function to a temporal interval in accordance with the distance; and locking the door using the automatic locking/unlocking function when the temporal interval has elapsed.

  • Patent number: 11300065
    Abstract: A control unit (8) calculates a temperature difference (?Tg). The temperature difference (?Tg) is a value obtained by subtracting the temperature (Tg) of a GPF (22) from a target GPF temperature (Tgt). If the temperature difference (?Tg) is less than or equal to zero, the control unit (8) implements a fuel economy-oriented conventional control. If the temperature difference (?Tg) is greater than zero, the control unit (8) implements a filter temperature-increasing control. The filter temperature-increasing control causes the exhaust temperature to be increased so that the temperature (Tg) of the GPF (22) becomes greater than or equal to the target GPF temperature (Tgt).

  • Patent number: 11302197
    Abstract: A vehicle behavior prediction device includes an objection detection device for detecting a position of an object, with respect to a host vehicle, located on the front side or the lateral side of the host vehicle, and a moving object traveling further than the object from the host vehicle, and an behavior prediction unit. The behavior prediction unit calculates, based on the position detected by the objection detection device, a blind spot region from the host vehicle caused by the object in which the objection detection device cannot detect. The behavior prediction unit presumes a detection-available period from a point when the moving object is detected to a point when the moving object enters the blind spot region in a case in which the moving object travels in a predetermined course after being detected by the objection detection device.
