  • Publication number: 20240134000
    Abstract: A radar system, a radar device, and an interference avoidance method are obtained that can utilize frequency effectively even in three or more radar devices. A radar system includes three or more radar devices and a schedule management controller. Schedule management controller predicts an interference time period that is a time period during which the overlapping scanning/radiation range is generated, determines a first interference avoidance measure that is a measure to cause radar devices to use respective different use frequencies while keeping a restriction on the number of frequency channels, in the predicted interference time period, and determines a second interference avoidance measure to be performed by a radar device that is unable to avoid interference by the first interference avoidance measure.

  • Publication number: 20180056987
    Abstract: An object of the present invention is to provide a vehicle control apparatus and a vehicle control method capable of improving traceability when a speed reduction torque is applied. A vehicle control apparatus according to the present invention is configured to calculate the speed reduction torque to be generated on a vehicle based on an accelerator operation state and a front wheel slip angle. More specifically, when being brought into a turning state while a coasting torque is applied, the vehicle control apparatus makes a correction so as to reduce an absolute value of the coasting torque, thereby improving the traceability and the drivability.

  • Patent number: 8892281
    Abstract: A control system for an electric vehicle has a vehicle speed calculation section that calculates a speed of the electric vehicle and a control unit that controls an inverter of an electric motor to provide road wheels with a predetermined reference torque in accordance with a manipulated value of an accelerator pedal, wherein the unit has a reference torque correction section that changes the reference torque from an original value and then returns the changed reference torque to the original value when a calculated speed of the electric vehicle is in a given speed range.

  • Patent number: 7000998
    Abstract: A brake control apparatus includes a vehicle sensor to sense a vehicle condition, and a control unit to start a hill hold control to hold a vehicle in a stop state by a braking force produced by a brake actuator even after an end of the driver's braking operation, in accordance with a hill hold control start adjustment parameter determined from the sensed vehicle condition. The parameter may be a variable indicative of a gradient of a road.
