  • Patent number: 10935973
    Abstract: Methods, apparatuses, systems, and non-transitory computer readable storage media for generating solution data for autonomous vehicles to negotiate problem situations have been disclosed. The disclosed technology generates state data associated with a vehicle using sensor data received from the vehicle and from external objects within a vicinity of the vehicle. The state data includes any of a location of the vehicle, a destination of the vehicle, an operational status of the vehicle, and information associated with a vehicle environment. In response to determining that the state data satisfies a state criterion, a determination of solution profile data that matches the state data is made on the basis of a comparison of the state data to the solution profile data. Solution data is generated using the matching solution profile data to transmit the solution data to the vehicle for execution.

  • Publication number: 20210054794
    Abstract: During a transient period, the opening degree of a throttle valve (throttle opening degree) is varied from a steady-period target throttle opening degree in a region A1 toward a valve closing side by a predetermined amount ?P, and is thereafter controlled so as to become a steady-period target throttle opening degree in the region A1. The transient period is a transient period in which the operation state is shifted from a region B2 in which an air-fuel ratio in a supercharged state becomes a predetermined lean air-fuel ratio to a region A1 in which the air-fuel ratio in a non-supercharged state becomes a predetermined rich air-fuel ratio richer than the lean air-fuel ratio. In this transient period, by reducing the air amount in a cylinder, the combustion torque of an internal combustion engine is suppressed, and consequently; a torque overshoot can be suppressed.

  • Publication number: 20210053560
    Abstract: A method detects a risk of collision between a motor vehicle and a secondary object located in traffic lanes adjacent to the main traffic lane of the vehicle, in the event of a lane change by the vehicle, which involves detecting objects in a predetermined danger zone, and estimating a time-to-collision between the vehicle and a detected object. Detecting objects in a danger zone involves: calculating the actual distance between the vehicle and each object detected by the radar, the actual distance corresponding to the length of an arc between two points; determining a danger zone as a function of lines of the main traffic lane and a width of the main traffic line; and checking, for each object detected by the radar, whether its coordinates are inside the predetermined danger zone.

    Abstract: A boost converter control method in one aspect of the present invention is the control method of the boost converter that boosts a voltage input from a power supply and supplies a boosted voltage to a load-side. The control method of the boost converter is securing an output electric power required according to an operation point of a motor connected to the load-side, calculating a lower limit voltage value at which the output voltage of the boost converter does not oscillate, setting a target output voltage of the boost converter to a value equal to or higher than the lower limit voltage, and controlling the boost converter so as to output a voltage according to the target output voltage.
